     FIELD OF THE INVENTION 
     The present invention relates to compositions comprising one or more polymeric suds volume and suds duration enhances which are mild on the users skin. The polymeric suds enhances are suitable for use in methods which in use as compositions light duty liquid, LDL compositions, hand dishwashing compositions, laundry bars, personal cleansing compositions and the like. 
     BACKGROUND OF THE INVENTION 
     In formulating detergent compositions which will foreseeable contact the users skin, such as Light-duty liquid or gel dishwashing detergent compositions laundry bars, personal cleansing compositions (such as shampoos and body washes) and the like the problem of mildness is of major concern. Furthermore, the formulator must also produce a composition which provides adequate cleaning for the desired end use. However, it is well know that the best cleaning surfactants, such as the anionic surfactants, for example LAS, AS etc., irritate the users skin.

     DETAILED DESCRIPTION OF THE INVENTION 
     The present invention relates to methods which in addition to providing increased suds volume and increase suds duration, are mild. The methods of the present invention comprise suds boosting polymers selected from (1) polymers comprising at least one monomeric unit; (2) proteinaceous suds stabilizer; (3) zwitterionic polymeric suds stabilizer; and (4) polymers comprising units capable of having a cationic charge. Suitable polymeric suds stabilizers, include be a homopolymers, as well as copolymers, terpolymers, and higher multimers. Mixtures of the polymeric suds stabilizers are also within the scope of the invention. 
     In addition, the polymers of the present invention act together with surfactants and other adjunct ingredients to provide for efficient grease cutting and anti-redepositon of grease. 
     It is believed, while not wanting to be limited by theory, that the suds boosting polymers functions primarily by providing a desquamatory action to the composition. It is believed that the suds boosting polymers remove damaged (e.g. dry) skin cells on the surface of the skin, thereby reducing the rough feel associated therewith. The suds boosting polymers removes the effect of prior damage to the skin, giving the skin a fresher, more youthful appearance and feel. When the suds boosting polymers is combined with a detergent surfactant the overall effect is to promote the health of the skin and to provide the consumer with a perceived mildness or skin feel/appearance advantage over other similar compositions which do not contain the suds boosting polymers while still maintaining good cleaning performance. 
     Alternatively, the polymeric suds stabilizers may, again while not wanting to be limited by theory, just improve the overall feel of the composition to the user.

     In one aspect of the present invention the polymeric suds stabilizers comprise at least one monomeric unit of the formula: 
                         
wherein each of R 1 , R 2  and R 3  are independently selected from the group consisting of hydrogen, C 1  to C 6  alkyl, and mixtures thereof, preferably hydrogen, C 1  to C 3  alkyl, more preferably, hydrogen or methyl. L is selected from the group consisting of a bond, O, NR 6 , SR 7 R 5  and mixtures thereof, preferably, O, NR 6 , wherein R 6  is selected from the group consisting of hydrogen, C 1  to C 8  alkyl and mixtures thereof, preferably, hydrogen, C 1  to C 3 , and mixtures thereof, more preferably hydrogen, methyl; each of R 7  and R 8  are independently hydrogen, O, C 1  to C 8  alkyl and mixtures thereof, preferably, hydrogen, C 1  to C 3 , and mixtures thereof, more preferably hydrogen or methyl.

wherein R and R 1  are independently hydrogen or a moiety as describe herein above preferably R 1  is hydrogen and at least from about  10 % to about 40% of R units comprise a moiety having a positive charge at a pH of from about 7 to about 11.5.

The aforementioned amino acids are typically referred to as the “primary a-amino acids”, however, the proteinaceous suds stabilizers of the present invention may comprise any amino acid having an R unit which together with the aforementioned amino acids serves to adjust the isoelectric point of the proteinaceous suds stabilizers to a range of from about 7 to about 11.5. For example, further non-limiting examples of amino acids include homoserine, hydroxyproline, norleucine, norvaline, ornithine, penicillamine, and phenylglycine, preferably ornithine. R units preferably comprise moieties which are capable of a cationic or anionic charges within the range of pH from about 7 to about 11.5. Non-limiting examples of preferred amino acids having anionic R units include glutamic acid, aspartic acid, and g-carboxyglutamic acid. 
     For the purposes of the present invention, both optical isomers of any amino acid having a chiral center serve equally well for inclusion into the backbone of the peptide, polypeptide, or amino acid copolymers. Racemic mixtures of one amino acid may be suitably combined with a single optical isomer of one or more other amino acids depending upon the desired properties of the final proteinaceous suds stabilizer. The same applies to amino acids capable of forming diasteriomeric pairs, for example, threonine. 
     Polyamino Acid Proteinaceous Suds Stabilizer—One type of suitable proteinaceous suds stabilizer according to the present invention is comprised entirely of the amino acids described herein above. Said polyamino acid compounds may be naturally occurring peptides, polypeptides, enzymes, and the like, provided said compounds have an isoelectric point of from about 7 to about 11.5 and a molecular weight greater than or equal to about 1500 daltons. Preferably the proteinaceous suds stabilizers of the present invention which are comprised entirely of amino acids, comprise from about 10% to about 40% by weight, of amino acids which are capable of being protonated at a pH of from about 7 to about 11.5. An example of a polyamino acid which is suitable as a proteinaceous suds stabilizer according to the present invention is the enzyme lysozyme. 
     An exception may, from time to time, occur in the case where naturally occurring enzymes, proteins, and peptides are chosen as proteinaceous suds stabilizers. Without wishing to be limited by theory, the unique secondary, tertiary, or quaternary structure of said naturally occurring polypeptides may permit their use even though the amount of protonatable amino acids within the pH range of from about 7 to about 11.5 is outside the range of from about 10% to about 40% by weight. For example an enzyme having an isoelectric point in the range of from about 7 to about 11.5 which only comprises 5% by weight amino acids having R units which are protonated at a pH of from about 7 to about 11.5 may suitably serve as an effective proteinaceous suds stabilizer according to the present invention. 
     Another class of suitable polyamino acid compound is the synthetic peptide having a molecular weight of at least about 1500 daltons and further comprising from about 10% to about 40% by weight of amino acids capable of being protonated at a pH of form about 7 to about 11.5. In addition, said polyamino acid peptides must have an isoelectric point of form 7 to about 11.5, preferably from about 8.5 to about 11.5, more preferably form about 9.5 to about 11. An example of a polyamino acid synthetic peptide suitable for use as a proteinaceous suds stabilizer according to the present invention is the copolymer of the amino acids lysine, alanine, glutamic acid, and tyrosine having an average molecular weight of 52,000 daltons and a ratio of lys:ala:glu:tyr of approximately 5:6:2:1. 
     Without wishing to be limited by theory, the presence of one or more cationic amino acids, for example, histidine, ornithine, lysine and the like, is required to insure increased suds stabilization and suds volume. However, the relative amount of cationic amino acid present, as well as the resulting isoelectric point of the polyamino acid, are key to the effectiveness of the resulting material. For example, poly L-lysine having a molecular weight of approximately 18,000 daltons comprises 100% amino acids which have the capacity to possess a positive charge in the pH range of from about 7 to about 11.5, with the result that this material is ineffective as a suds extender and as a greasy soil removing agent. 
     Peptide Copolymers—Another class of materials suitable for use as proteinaceous suds stabilizers according to the present invention are peptide copolymers. For the purposes of the present invention “peptide copolymers” are defined as “polymeric materials with a molecular weight greater than or equal to about 1500 daltons having an isoelectric point of from about 7 to about 11.5 wherein at least about 10% by weight of said polymeric material comprises one or more amino acids”. 
     Peptide copolymers suitable for use as proteinaceous suds stabilizers may include segments of polyethylene oxide which are linked to segments of peptide or polypeptide to form a material which has increased suds retention as well as formulatability. 
     Nonlimiting examples of amino acid copolymer classes include the following. 
     A. Polyalkyleneimine Copolymers. 
     Polyalkyleneimine copolymers comprise random segments of polyalkyleneimine, preferably polyethyleneimine, together with segments of amino acid residues. For example, tetraethylenepentamine is reacted together with polyglutamic acid and polyalanine to form a copolymer having the formula: 
                         
wherein m is equal to 3, n is equal to 0, i is equal to 3, j is equal to 5, x is equal to 3, y is equal to 4, and z is equal to 7.
 
     However, the formulator may substitute other polyamines for polyalkyleneimines, for example, polyvinyl amines, or other suitable polyamine which provides for a source of cationic charge at a pH of from 7 to abut 11.5 and which results in a copolymer having an isoelectric point of from about 7 to about 11.5. 
     The formulator may combine non-amine polymers with protonatable as well as non-protonatable amino acids. For example, a carboxylate-containing homo-polymer may be reacted with one or more amino acids, for example, histidine and glycine, to form an amino acid containing amido copolymer having the formula: 
                         
wherein said copolymer has a molecular weight of at least 1500 daltons and a ratio of x:y:z of approximately 2:3:6.
 
     The proteinaceous polymeric suds stabilizers when used in the methods of the present invention are present at an effective amount of one or more proteinaceous suds stabilizers described herein, preferably from about 0.3% to about 5%, more preferably from about 0.4% to about 4%, most preferably from about 0.5% to about 3% by weight, of said composition. What is meant herein by “an effective amount of proteinaceous suds stabilizer” is that the suds produced by the presently described compositions are sustained for an increased amount of time relative to a composition which does not comprise a proteinaceous suds stabilizer described herein. 
     These and other suitable polymeric suds stabilizers and methods for preparing them, can be found in PCT/US98/24707 filed Nov. 20, 1998.

     For illustrative purposes only, a polypeptide comprising 10 units of the amino acid lysine has a molecular weight of approximately 1028 daltons, wherein there are 11 —NH 2  units. If at a specific pH within the range of from about 4 to about 12, 2 of the —NH 2  units are protonated in the form of —NH 3   + , then the cationic charge density is 2 cationic charge units÷by 1028 daltons molecular weight=approximately 0.002 units of cationic charge per 100 daltons. This would, therefore, have sufficient cationic charge to suffice the cationic charge density of the present invention, but insufficient molecular weight to be a suitable suds enhancer. 
     Polymers have been shown to be effective for delivering sudsing benefits provided the polymer contains a cationic moiety, either permanent via a quaternary nitrogen or temporary via protonation. Without being limited by theory, it is believed that the cationic charge must be sufficient to attract the polymer to negatively charged soils but not so large as to cause negative interactions with available anionic surfactants. Herewithin the term cationic charge density is defined as the amount of cationic charge on a given polymer, either by permanent cationic groups or via protonated groups, as a weight percent of the total polymer at the desired wash pH. For example, with poly(-DMAM), we have experimentally determined the pKa, see hereinafter as to how pKa is measured, of this polymer to be 7.0. Thus, if the wash pH is 7.0, then half of the available nitrogens will be protonated (and count as cationic) and the other half will not be protonated (and not be counted in the “cationic charge density”). Thus, since the Nitrogen has a molecular weight of approximately 14 grams/mole, and the DMAM monomer has a molecular weight of approximately 157 grams/mole, the can be calculated:
 
Cationic Charge Density=(14/157)*50%=0.0446 or 4.46%.
 
Thus, 4.46% of the polymer contains cationic charges. As another example, one could make a copolymer of DMAM with DMA, where the ratio of monomers is 1 mole of DMAM for 3 moles of DMA. The DMA monomer has a molecular weight of 99 grams/mole. In this case the pKa has been measured to be 7.6. Thus, if the wash pH is 5.0, all of the available nitrogens will be protonated. The cationic charge density is then calculated:
 
Cationic Charge Density=14/(157+99+99+99)*100%=0.0103, or 1.03%.
 
Notice that in this example, the minimum repeating unit is considered 1 DMAM monomer plus 3 DMA monomers.
 
     A key aspect of this calculation is the pKa measurement for any protonatable species which will result in a cationic charge on the heteroatom. Since the pKa is dependent on the polymer structure and various monomers present, this must be measure to determine the percentage of protonatable sites to count as a function of the desired wash pH. This is an easy exercise for one skilled in the art. 
     Based on this calculation, the percent of cationic charge is independent of polymer molecular weight. 
     The pKa of a polymeric suds booster is determined in the following manner. Make at least 50 mls of a 5% polymer solution, such as a polymer prepared according to any of Examples 1 to 5 as described hereinafter, in ultra pure water (i.e. no added salt). At 25° C., take initial pH of the 5% polymer solution with a pH meter and record when a steady reading is achieved. Maintain temperature throughout the test at 25° C. with a water bath and stir continuously. Raise pH of 50 mls of the aqueous polymer solution to 12 using NaOH (1N, 12.5M). Titrate 5 mls of 0.1N HCl into the polymer solution. Record pH when steady reading is achieved. Repeat steps 4 and 5 until pH is below 3. The pKa was determined from a plot of pH vs. volume of titrant using the standard procedure as disclosed in Quantitative Chemical Analysis, Daniel C. Harris, W.H. Freeman &amp; Chapman, San Francisco, USA 1982.

     These and other suitable polymeric suds stabilizers and methods of preparing them, can be found in PCT/US98/24852 filed Nov. 20, 1998 (Docket No. 6944).

     Also proteases described in our co-pending application U.S. Ser. No. 08/136,797 can be included in the detergent composition of the invention. 
     Another preferred protease, referred to as “Protease D”, is a carbonyl hydrolase variant described in WO 95/10615 published Apr. 20, 1995 by Genencor International (A. Baeck et al. entitled “Protease-Containing Cleaning Compositions” having U.S. Ser. No. 08/322,676, filed Oct. 13, 1994). 
     Useful proteases are also described in PCT publications: WO 95/30010 published Nov. 9, 1995 by The Procter &amp; Gamble Company; WO 95/30011 published Nov. 9, 1995 by The Procter &amp; Gamble Company; WO 95/29979 published Nov. 9, 1995 by The Procter &amp; Gamble Company.

     Amylase enzymes also include those described in WO95/26397 and in co-pending application by Novo Nordisk PCT/DK96/00056. Other specific amylase enzymes for use in the detergent compositions of the present invention therefore include: 
     α-amylases characterised by having a specific activity at least 25% higher than the specific activity of Termamyl® at a temperature range of 25° C. to 55° C. and at a pH value in the range of 8 to 10, measured by the Phadebas® α-amylase activity assay. as described at pages 9–10, WO95/26397; and variants of amylase as described. in the patent application PCT/DK96/00056. 
     Other amylases suitable herein include, for example, α-amylases described in GB 1,296,839 to Novo; RAPIDASE®, International Bio-Synthetics, Inc. and TERMAMYL®, Novo. FUNGAMYL® from Novo is especially useful. Engineering of enzymes for improved stability, e.g., oxidative stability, is known. See, for example J. Biological Chem., Vol. 260, No. 11, June 1985, pp. 6518–6521. Certain preferred embodiments of the present compositions can make use of amylases having improved stability in detergents such as automatic dishwashing types, especially improved oxidative stability as measured against a reference-point of TERMAMYL® in commercial use in 1993. These preferred amylases herein share the characteristic of being “stability-enhanced” amylases, characterized, at a minimum, by a measurable improvement in one or more of: oxidative stability, e.g., to hydrogen peroxide/tetraacetylethylenediamine in buffered solution at pH 9–10; thermal stability, e.g., at common wash temperatures such as about 60° C.; or alkaline stability, e.g., at a pH from about 8 to about 11, measured versus the above-identified reference-point amylase. Stability can be measured using any of the art-disclosed technical tests. See, for example, references disclosed in WO 9402597. Stability-enhanced amylases can be obtained from Novo or from Genencor International. One class of highly preferred amylases herein have the commonality of being derived using site-directed mutagenesis from one or more of the  Bacillus  amylases, especially the  Bacillus  α-amylases, regardless of whether one, two or multiple amylase strains are the immediate precursors. Oxidative stability-enhanced amylases vs. the above-identified reference amylase are preferred for use, especially in bleaching, more preferably oxygen bleaching, as distinct from chlorine bleaching, detergent compositions herein. Such preferred amylases include (a) an amylase according to the hereinbefore incorporated WO 9402597, Novo, Feb. 3, 1994, as further illustrated by a mutant in which substitution is made, using alanine or threonine, preferably threonine, of the methionine residue located in position 197 of the  B. licheniformis  alpha-amylase, known as TERMAMYL®, or the homologous position variation of a similar parent amylase, such as  B. amyloliquefaciens, B. subtilis , or  B. stearothermophilus ; (b) stability-enhanced amylases as described by Genencor International in a paper entitled “Oxidatively Resistant alpha-Amylases” presented at the 207th American Chemical Society National Meeting, Mar. 13–17, 1994, by C. Mitchinson. Therein it was noted that bleaches in automatic dishwashing detergents inactivate alpha-amylases but that improved oxidative stability amylases have been made by Genencor from  B. licheniformis  NCIB8061. Methionine (Met) was identified as the most likely residue to be modified. Met was substituted, one at a time, in positions 8, 15, 197, 256, 304, 366 and 438 leading to specific mutants, particularly important being M197L and M197T with the M197T variant being the most stable expressed variant. Stability was measured in CASCADE® and SUNLIGHT®; (c) particularly preferred amylases herein include amylase variants having additional modification in the immediate parent as described in WO 9510603 A and are available from the assignee, Novo, as DURAMYL®. Other particularly preferred oxidative stability enhanced amylase include those described in WO 9418314 to Genencor International and WO 9402597 to Novo. Any other oxidative stability-enhanced amylase can be used, for example as derived by site-directed mutagenesis from known chimeric, hybrid or simple mutant parent forms of available amylases. Other preferred enzyme modifications are accessible. See WO 9509909 A to Novo.

Nos. 5,041,236, 5,395,541, 5,238,843 and 5,356,803 the disclosures of which are herein incorporated by reference. Of course, other enzymes having antimicrobial activity may be employed as well including peroxidases, oxidases and various other enzymes.

Carriers such as diethylphthalate can be used in the finished perfume compositions. 
     Chelating Agents—The detergent compositions used in the methods herein may also optionally contain one or more iron and/or manganese chelating agents. Such chelating agents can be selected from the group consisting of amino carboxylates, amino phosphonates, polyfunctionally-substituted aromatic chelating agents and mixtures therein, all as hereinafter defined. Without intending to be bound by theory, it is believed that the benefit of these materials is due in part to their exceptional ability to remove iron and manganese ions from washing solutions by formation of soluble chelates. 
     Amino carboxylates useful as optional chelating agents include ethylenediaminetetrace-tates, N-hydroxyethylethylenediaminetriacetates, nitrilo-tri-acetates, ethylenediamine tetrapro-prionates, triethylenetetraaminehexacetates, diethylenetriaminepentaacetates, and ethanoldi-glycines, alkali metal, ammonium, and substituted ammonium salts therein and mixtures therein. 
     Amino phosphonates are also suitable for use as chelating agents in the compositions of the invention when at lease low levels of total phosphorus are permitted in detergent compositions, and include ethylenediaminetetrakis (methylenephosphonates) as DEQUEST. Preferred, these amino phosphonates to not contain alkyl or alkenyl groups with more than about 6 carbon atoms. 
     Polyfunctionally-substituted aromatic chelating agents are also useful in the compositions herein. See U.S. Pat. No. 3,812,044, issued May 21, 1974, to Connor et al. Preferred compounds of this type in acid form are dihydroxydisulfobenzenes such as 1,2-dihydroxy-3,5-disulfobenzene. 
     A preferred biodegradable chelator for use herein is ethylenediamine disuccinate (“EDDS”), especially the [S,S] isomer as described in U.S. Pat. No. 4,704,233, Nov. 3, 1987, to Hartman and Perkins. 
     The compositions herein may also contain water-soluble methyl glycine diacetic acid (MGDA) salts (or acid form) as a chelant or co-builder. Similarly, the so called “weak” builders such as citrate can also be used as chelating agents. 
     If utilized, these chelating agents will generally comprise from about 0.1% to about 15% by weight of the detergent compositions herein. More preferably, if utilized, the chelating agents will comprise from about 0.1% to about 3.0% by weight of such compositions. 
     Composition pH—The compositions used in the methods of the invention will be subjected to acidic stresses created by soils, such as food, when put to use, i.e., diluted and applied to soiled dishes. If a composition with a pH greater than 7 is to be more effective, it preferably should contain a buffering agent capable of providing a generally more alkaline pH in the composition and in dilute solutions, i.e., about 0.1% to 0.4% by weight aqueous solution, of the composition. The pK a  value of this buffering agent should be about 0.5 to 1.0 pH units below the desired pH value of the composition (determined as described above). Preferably, the pK a  of the buffering agent should be from about 7 to about 10. Under these conditions the buffering agent most effectively controls the pH while using the least amount thereof. 
     The buffering agent may be an active detergent in its own right, or it may be a low molecular weight, organic or inorganic material that is used in this composition solely for maintaining an alkaline pH. Preferred buffering agents for compositions of this invention are nitrogen-containing materials. Some examples are amino acids such as lysine or lower alcohol amines like mono-, di-, and tri-ethanolamine. Other preferred nitrogen-containing buffering agents are Tri(hydroxymethyl)amino methane (HOCH 2 ) 3 CNH 3  (TRIS), 2-amino-2-ethyl-1,3-propanediol, 2-amino-2-methyl-propanol, 2-amino-2-methyl-1,3-propanol, disodium glutamate, N-methyl diethanolamide, 1,3-diamino-propanol N,N′-tetra-methyl-1,3-diamino-2-propanol, N,N-bis(2-hydroxyethyl)glycine (bicine) and N-tris (hydroxymethyl)methyl glycine (tricine). Mixtures of any of the above are also acceptable. Useful inorganic buffers/alkalinity sources include the alkali metal carbonates and alkali metal phosphates, e.g., sodium carbonate, sodium polyphosphate. For additional buffers see McCutcheon&#39;s EMULSIFIERS AND DETERGENTS, North American Edition, 1997, McCutcheon Division, MC Publishing Company Kirk and WO 95/07971 both of which are incorporated herein by reference. 
     The buffering agent, if used, is present in the compositions of the invention herein at a level of from about 0.1% to 15%, preferably from about 1% to 10%, most preferably from about 2% to 8%, by weight of the composition. 
     Calcium and/or Magnesium Ions—For LDL compositions the presence of calcium and/or magnesium (divalent) ions improves the cleaning of greasy soils for various compositions, i.e., compositions containing alkyl ethoxy sulfates and/or polyhydroxy fatty acid amides. This is especially true when the compositions are used in softened water that contains few divalent ions. It is believed that calcium and/or magnesium ions increase the packing of the surfactants at the oil/water interface, thereby reducing interfacial tension and improving grease cleaning. 
     Compositions used in the methods of the invention herein containing magnesium and/or calcium ions exhibit good grease removal, manifest mildness to the skin, and provide good storage stability. These ions may be optionally present in the compositions herein at an active level of from about 0.1% to 4%, preferably from about 0.3% to 3.5%, more preferably from about 0.5% to 1%, by weight. 
     Preferably, the magnesium or calcium ions are added as a hydroxide, chloride, acetate, formate, oxide or nitrate salt to the compositions of the present invention. Calcium ions may also be added as salts of the hydrotrope. 
     The amount of calcium or magnesium ions present in compositions of the invention will be dependent upon the amount of total surfactant present therein. When calcium ions are present in the compositions of this invention, the molar ratio of calcium ions to total anionic surfactant should be from about 0.25:1 to about 2:1. 
     Formulating such divalent ion-containing compositions in alkaline pH matrices may be difficult due to the incompatibility of the divalent ions, particularly magnesium, with hydroxide ions. When both divalent ions and alkaline pH are combined with the surfactant mixture of this invention, grease cleaning is achieved that is superior to that obtained by either alkaline pH or divalent ions alone. Yet, during storage, the stability of these compositions becomes poor due to the formation of hydroxide precipitates. Therefore, chelating agents discussed hereinbefore may also be necessary. 
     Other Ingredients—The detergent compositions used in the methods of the present invention may further preferably comprise one or more detersive adjuncts selected from the following: soil release polymers, polymeric dispersants, polysaccharides, abrasives, bactericides, tarnish inhibitors, builders, enzymes, opacifiers, dyes, buffers, antifungal or mildew control agents, insect repellents, perfumes, hydrotropes, thickeners, processing aids, suds boosters, brighteners, anti-corrosive aids, stabilizers antioxidants and chelants. A wide variety of other ingredients useful in detergent compositions can be included in the compositions herein, including other active ingredients, carriers, hydrotropes, antioxidants, processing aids, dyes or pigments, solvents for liquid formulations, solid fillers for bar compositions, etc. If high sudsing is desired, suds boosters such as the C 10 –C 16  alkanolamides can be incorporated into the compositions, typically at 1%–10% levels. The C 10 –C 14  monoethanol and diethanol amides illustrate a typical class of such suds boosters. Use of such suds boosters with high sudsing adjunct surfactants such as the amine oxides, betaines and sultaines noted above is also advantageous. 
     An antioxidant can be optionally added to the detergent compositions of the present invention. They can be any conventional antioxidant used in detergent compositions, such as 2,6-di-tert-butyl-4-methylphenol (BHT), carbamate, ascorbate, thiosulfate, monoethanolamine (MEA), diethanolamine, triethanolamine, etc. It is preferred that the antioxidant, when present, be present in the composition from about 0.001% to about 5% by weight. 
     Various detersive ingredients employed in the present compositions optionally can be further stabilized by absorbing said ingredients onto a porous hydrophobic substrate, then coating said substrate with a hydrophobic coating. Preferably, the detersive ingredient is admixed with a surfactant before being absorbed into the porous substrate. In use, the detersive ingredient is released from the substrate into the aqueous washing liquor, where it performs its intended detersive function. 
     To illustrate this technique in more detail, a porous hydrophobic silica (trademark SIPERNAT D10, DeGussa) is admixed with a proteolytic enzyme solution containing 3%–5% of C 13-15  ethoxylated alcohol (EO 7) nonionic surfactant. Typically, the enzyme/surfactant solution is 2.5× the weight of silica. The resulting powder is dispersed with stirring in silicone oil (various silicone oil viscosities in the range of 500–12,500 can be used). The resulting silicone oil dispersion is emulsified or otherwise added to the final detergent matrix. By this means, ingredients such as the aforementioned enzymes, bleaches, bleach activators, bleach catalysts, photoactivators, dyes, fluorescers, fabric conditioners and hydrolyzable surfactants can be “protected” for use in detergents, including liquid laundry detergent compositions. 
     Further, these hand dishwashing detergent embodiments preferably further comprises a hydrotrope. Suitable hydrotropes include sodium, potassium, ammonium or water-soluble substituted ammonium salts of toluene sulfonic acid, naphthalene sulfonic acid, cumene sulfonic acid, xylene sulfonic acid. 
     The detergent compositions of this invention can be in any form, including granular, paste, gel or liquid. Highly preferred embodiments are in liquid or gel form. Liquid detergent compositions can contain water and other solvents as carriers. Low molecular weight primary or secondary alcohols exemplified by methanol, ethanol, propanol, and isopropanol are suitable. Monohydric alcohols are preferred for solubilizing surfactant, but polyols such as those containing from 2 to about 6 carbon atoms and from 2 to about 6 hydroxy groups (e.g., 1,3-propanediol, ethylene glycol, glycerine, and 1,2-propanediol) can also be used. The compositions may contain from 5% to 90%, typically 10% to 50% of such carriers. 
     An example of the procedure for making granules of the detergent compositions herein is as follows:—Linear aklylbenzenesulfonate, citric acid, sodium silicate, sodium sulfate perfume, diamine and water are added to, heated and mixed via a crutcher. The resulting slurry is spray dried into a granular form. 
     An example of the procedure for making liquid detergent compositions herein is as follows:—To the free water and citrate are added and dissolved. To this solution amine oxide, betaine, ethanol, hydrotrope and nonionic surfactant are added. If free water isn&#39;t available, the citrate are added to the above mix then stirred until dissolved. At this point, an acid is added to neutralize the formulation. It is preferred that the acid be chosen from organic acids such as maleic and citric, however, inorganic mineral acids may be employed as well. In preferred embodiments these acids are added to the formulation followed by diamine addition. AExS is added last.

     The personal cleansing compositions used in the methods of the present invention comprise from about 0.005% to about 20%, preferably from about 0.01% to about 10%, more preferably from about 0.1% to about 5%, and even more preferably from about 0.5% to about 3% of dispersed particles of a nonvolatile hair or skin conditioning agent. Suitable hair or skin conditioning agents include nonvolatile silicone conditioning agents, nonvolatile hydrocarbon conditioning agents, and mixtures thereof. 
     As used herein, average particle size of the conditioning agent particles may be measured within the personal cleansing compositions by light scattering methods well known in the art for determining average particle size for emulsified liquids. One such method involves the use of a Horiba LA-910 particle size analyzer. 
     For more information and additional examples of conditioning agents see copending U.S. patent application Ser. No. 08/733,046, Attorney docket No 6303 filed on Oct. 16, 1996 and U.S. patent application Ser. No. 08/738,156, Attorney docket No 6331 filed on Oct. 25, 1996. See also U.S Pat. No. 4,741,855. All three of these references are incorporated herein by reference. 
     1) Nonvolatile Silicone Conditioning Agents—Preferred conditioning agents useful herein include nonvolatile, dispersed silicone conditioning agents. By nonvolatile is meant that the silicone conditioning agent exhibits very low or no significant vapor pressure at ambient conditions, e.g., 1 atmosphere at 25° C. The nonvolatile silicone conditioning agent preferably has a boiling point at ambient pressure of above about 250° C., preferably of above about 260° C., and more preferably of above about 275° C. By dispersed is meant that the conditioning agent forms a separate, discontinuous phase from the aqueous carrier such as in the form of an emulsion or a suspension of droplets. 
     The nonvolatile silicone hair conditioning agents suitable for use herein preferably have a viscosity of from about 1,000 to about 2,000,000 centistokes at 25° C., more preferably from about 10,000 to about 1,800,000, and even more preferably from about 100,000 to about 1,500,000. The viscosity can be measured by means of a glass capillary viscometer as set forth in Dow Corning Corporate Test Method CTM0004, Jul. 20, 1970, which is incorporated by reference herein in its entirety. Suitable silicone fluids include polyalkyl siloxanes, polyaryl siloxanes, polyalkylaryl siloxanes, polyether siloxane copolymers, and mixtures thereof. Other nonvolatile silicones having hair conditioning properties can also be used. 
     The silicones herein also include polyalkyl or polyaryl siloxanes with the following structure: 
                         
wherein R is alkyl or aryl, and x is an integer from about 7 to about 8,000. “A” represents groups which block the ends of the silicone chains. The alkyl or aryl groups substituted on the siloxane chain (R) or at the ends of the siloxane chains (A) can have any structure as long as the resulting silicone remains fluid at room temperature, is dispersible, is neither irritating, toxic nor otherwise harmful when applied to the hair, is compatible with the other components of the composition, is chemically stable under normal use and storage conditions, and is capable of being deposited on and conditions the hair. Suitable A groups include hydroxy, methyl, methoxy, ethoxy, propoxy, and aryloxy. The two R groups on the silicon atom may represent the same group or different groups. Preferably, the two R groups represent the same group. Suitable R groups include methyl, ethyl, propyl, phenyl, methylphenyl and phenylmethyl. The preferred silicones are polydimethyl siloxane, polydiethylsiloxane, and polymethylphenylsiloxane. Polydimethylsiloxane, which is also known as dimethicone, is especially preferred. The polyalkylsiloxanes that can be used include, for example, polydimethylsiloxanes. These silicones are available, for example, from the General Electric Company in their ViscasilR and SF 96 series, and from Dow Corning in their Dow Corning 200 series.
 
     Polyalkylaryl siloxane fluids can also be used and include, for example, polymethylphenylsiloxanes. These siloxanes are available, for example, from the General Electric Company as SF 1075 methyl phenyl fluid or from Dow Corning as 556 Cosmetic Grade Fluid. 
     Especially preferred, for enhancing the shine characteristics of hair, are highly arylated silicones, such as highly phenylated polyethyl silicone having refractive indices of about 1.46 or higher, especially about 1.52 or higher. When these high refractive index silicones are used, they should be mixed with a spreading agent, such as a surfactant or a silicone resin, as described below to decrease the surface tension and enhance the film forming ability of the material. 
     The silicones that can be used include, for example, a polypropylene oxide modified polydimethylsiloxane although ethylene oxide or mixtures of ethylene oxide and propylene oxide can also be used. The ethylene oxide and polypropylene oxide level should be sufficiently low so as not to interfere with the dispersibility characteristics of the silicone. These material are also known as dimethicone copolyols. 
     Other silicones include amino substituted materials. Suitable alkylamino substituted silicones include those represented by the following structure (II) 
                         
wherein x and y are integers which depend on the molecular weight, the average molecular weight being approximately between 5,000 and 10,000. This polymer is also known as “amodimethicone”.
 
     Suitable cationic silicone fluids include those represented by the formula (III) (R 1 ) a G 3-a -Si—(—OSiG 2 ) n -(—OSiG b (R 1 ) 2-b)m —O—SiG 3-a (R 1 ) a  in which G is chosen from the group consisting of hydrogen, phenyl, OH, C 1 –C 8  alkyl and preferably methyl; a denotes 0 or an integer from 1 to 3, and preferably equals 0; b denotes 0 or 1 and preferably equals 1; the sum n+m is a number from 1 to 2,000 and preferably from 50 to 150, n being able to denote a number from 0 to 1,999 and preferably from 49 to 149 and m being able to denote an integer from 1 to 2,000 and preferably from 1 to 10; R 1  is a monovalent radical of formula C q H 2q L in which q is an integer from 2 to 8 and L is chosen from the groups
 
—N(R 2 )CH 2 —CH 2 —N(R 2 ) 2 
 
—N(R 2 ) 2 
 
—N(R 2 ) 3 A − 
 
—N(R 2 )CH 2 —CH 2 —NR 2 H 2 A − 
 
in which R 2  is chosen from the group consisting of hydrogen, phenyl, benzyl, a saturated hydrocarbon radical, preferably an alkyl radical containing from 1 to 20 carbon atoms, and A −  denotes a halide ion.
 
     An especially preferred cationic silicone corresponding to formula (III) is the polymer known as “trimethylsilylamodimethicone”, of formula (IV): 
     
       
         
         
             
             
         
       
     
     In this formula n and m are selected depending on the exact molecular weight of the compound desired. 
     Other silicone cationic polymers which can be used in the personal cleansing compositions are represented by the formula (V): 
                         
where R 3  denotes a monovalent hydrocarbon radical having from 1 to 18 carbon atoms, preferably an alkyl or alkenyl radical such as methyl; R 4  denotes a hydrocarbon radical, preferably a C 1 –C 18  alkylene radical or a C 1 –C 18 , and more preferably C 1 –C 8 , alkyleneoxy radical; Q −  is a halide ion, preferably chloride; r denotes an average statistical value from 2 to 20, preferably from 2 to 8; s denotes an average statistical value from 20 to 200, and preferably from 20 to 50. A preferred polymer of this class is available from Union Carbide under the name “UCAR SILICONE ALE 56.”

No. 4,364,837, to Pader; and British Patent No. 849,433, to Woolston, all of which are incorporated herein by reference in their entirety. Also incorporated herein by reference in its entirety is “Silicon Compounds” distributed by Petrarch Systems, Inc., 1984. This reference provides an extensive, though not exclusive, listing of suitable silicones. 
     Another silicone hair conditioning material that can be especially useful is a silicone gum. The term “silicone gum”, as used herein, means a polyorganosiloxane material having a viscosity at 25° C. of greater than or equal to 1,000,000 centistokes. It is recognized that the silicone gums described herein can also have some overlap with the above-disclosed silicones. This overlap is not intended as a limitation on any of these materials. Silicone gums are described by Petrarch, Id., and others including U.S. Pat. No. 4,152,416, to Spitzer et al., issued May 1, 1979 and Noll, Walter,  Chemistry and Technology of Silicones , New York: Academic Press 1968. Also describing silicone gums are General Electric Silicone Rubber Product Data Sheets SE 30, SE 33, SE 54 and SE 76. All of these described references are incorporated herein by reference in their entirety. The “silicone gums” will typically have a mass molecular weight in excess of about 200,000, generally between about 200,000 and about 1,000,000. Specific examples include polydimethylsiloxane, (polydimethylsiloxane) (methylvinylsiloxane) copolymer, poly(dimethylsiloxane) (diphenyl siloxane)(methylvinylsiloxane) copolymer and mixtures thereof. 
     Also useful are silicone resins, which are highly crosslinked polymeric siloxane systems. The crosslinking is introduced through the incorporation of trifunctional and tetrafunctional silanes with monofunctional or difunctional, or both, silanes during manufacture of the silicone resin. As is well understood in the art, the degree of crosslinking that is required in order to result in a silicone resin will vary according to the specific silane units incorporated into the silicone resin. In general, silicone materials which have a sufficient level of trifunctional and tetrafunctional siloxane monomer units, and hence, a sufficient level of crosslinking, such that they dry down to a rigid, or hard, film are considered to be silicone resins. The ratio of oxygen atoms to silicon atoms is indicative of the level of crosslinking in a particular silicone material. Silicone materials which have at least about 1.1 oxygen atoms per silicon atom will generally be silicone resins herein. Preferably, the ratio of oxygen:silicon atoms is at least about 1.2:1.0. Silanes used in the manufacture of silicone resins include monomethyl-, dimethyl-, trimethyl-, monophenyl-, diphenyl-, methylphenyl-, monovinyl-, and methylvinyl-chlorosilanes, and tetrachlorosilane, with the methyl-substituted silanes being most commonly utilized. Preferred resins are offered by General Electric as GE SS4230 and SS4267. Commercially available silicone resins will generally be supplied in a dissolved form in a low viscosity volatile or nonvolatile silicone fluid. The silicone resins for use herein should be supplied and incorporated into the present compositions in such dissolved form, as will be readily apparent to those skilled in the art. Without being limited by theory, it is believed that the silicone resins can enhance deposition of other silicones on the hair and can enhance the glossiness of hair with high refractive index volumes. 
     Other useful silicone resins are silicone resin powders such as the material given the CTFA designation polymethylsilsequioxane, which is commercially available as Tospearl™ from Toshiba Silicones. 
     Background material on silicones, including sections discussing silicone fluids, gums, and resins, as well as the manufacture of silicones, can be found in Encyclopedia of Polymer Science and Engineering, Volume 15, Second Edition, pp 204–308, John Wiley &amp; Sons, Inc., 1989, which is incorporated herein by reference in its entirety. 
     Silicone materials and silicone resins in particular, can conveniently be identified according to a shorthand nomenclature system well known to those skilled in the art as the “MDTQ” nomenclature. Under this system, the silicone is described according to the presence of various siloxane monomer units which make up the silicone. Briefly, the symbol M denotes the monofunctional unit (CH 3 ) 3 SiO 0.5 ; D denotes the difunctional unit (CH 3 ) 2 SiO; T denotes the trifunctional unit (CH 3 )SiO 1.5 ; and Q denotes the quadri- or tetra-functional unit SiO 2 . Primes of the unit symbols, e.g., M′, D′, T′, and Q′ denote substituents other than methyl, and must be specifically defined for each occurrence. Typical alternate substituents include groups such as vinyl, phenyl, amino, hydroxyl, etc. The molar ratios of the various units, either in terms of subscripts to the symbols indicating the total number of each type of unit in the silicone, or an average thereof, or as specifically indicated ratios in combination with molecular weight, complete the description of the silicone material under the MDTQ system. Higher relative molar amounts of T, Q, T′ and/or Q′ to D, D′, M and/or or M′ in a silicone resin is indicative of higher levels of crosslinking. As discussed before, however, the overall level of crosslinking can also be indicated by the oxygen to silicon ratio. 
     The silicone resins for use herein which are preferred are MQ, MT, MTQ, MQ and MDTQ resins. Thus, the preferred silicone substituent is methyl. Especially preferred are MQ resins wherein the M:Q ratio is from about 0.5:1.0 to about 1.5:1.0 and the average molecular weight of the resin is from about 1000 to about 10,000. 
     2) Nonvolatile Hydrocarbon Conditioning Agents—Other suitable hair conditioning agents suitable for use in the personal cleansing composition include nonvolatile organic conditioning agents. Suitable nonvolatile organic conditioning agents for use in the composition are those conditioning agents that are known or otherwise effective for use as hair or skin conditioning agent. 
     The nonvolatile hydrocarbons for use in the personal cleansing composition may be saturated or unsaturated, and may be straight, cyclic or branched chain. By nonvolatile is meant that the hydrocarbon conditioning agent exhibits very low or no significant vapor pressure at ambient conditions, e.g., 1 atmosphere at 25° C. The nonvolatile hydrocarbon agent preferably has a boiling point at ambient pressure of above about 250° C., preferably above about 260° C., and more preferably of above about 275° C. The nonvolatile hydrocarbons preferably have from about 12 to about 40 carbon atoms, more preferably from about 12 to about 30 carbon atoms, and most preferably from about 12 to about 22 carbon atoms. Also encompassed herein are polymeric hydrocarbons of alkenyl monomers, such as polymers of C 2 –C 12  alkenyl monomers, including 1-alkenyl monomers such as polyalphaolefin monomers. These polymers can be straight or branched chain polymers. The straight chain polymers will typically be relatively short in length, having a total number of carbon atoms as described above in this paragraph. The branched chain polymers can have substantially higher chain lengths. Also useful herein are the various grades of mineral oils. Mineral oils are liquid mixtures of hydrocarbons that are obtained from petroleum. 
     Specific examples of suitable nonvolatile hydrocarbons include, but are not limited to, paraffin oil, mineral oil, dodecane, isododecane, hexadecane, isohexadecane, eicosene, isoeicosene, tridecane, triglyceride oils, tetradecane, polyoctene, polydecene, polydodecene, products of polymerization of mixtures of C 2-12  monomers, for example the polymer produced by the polymerization of polyoctene, polydecene and polydodecene, and mixtures thereof. Isododecane, isohexadeance, and isoeicosene are commercially available as Permethyl 99A, Permethyl 101A, and Permethyl 1082, from Presperse, South Plainfield, N.J. A copolymer of isobutene and normal butene is commercially available as Indopol H-100 from Amoco Chemicals. Preferred among these hydrocarbons are mineral oil, isododecane, isohexadecane, polybutene, polyisobutene, and mixtures thereof. 
     Optional Suspending Agent—The personal cleansing compositions used in the methods of the present invention may further comprise a suspending agent at concentrations effective for suspending the optional conditioning agent, or other water-insoluble material, in dispersed form in the personal cleansing compositions. Such concentrations range from about 0.1% to about 10%, preferably from about 0.5% to about 5.0%, by weight of the personal cleansing compositions. 
     Optional suspending agents include crystalline suspending agents that can be categorized as acyl derivatives, long chain amine oxides, or combinations thereof, concentrations of which range from about 0.3% to about 5.0%, preferably from about 0.5% to about 3.0%, by weight of the personal cleansing compositions. When used in the personal cleansing compositions, these suspending agents are present in crystalline form. These suspending agents are described in U.S. Pat. No. 4,741,855, which description is incorporated herein by reference. These preferred suspending agents include ethylene glycol esters of fatty acids preferably having from about 16 to about 22 carbon atoms. More preferred are the ethylene glycol stearates, both mono and distearate, but particularly the distearate containing less than about 7% of the mono stearate. Other suitable suspending agents include alkanol amides of fatty acids, preferably having from about 16 to about 22 carbon atoms, more preferably about 16 to 18 carbon atoms, preferred examples of which include stearic monoethanolamide, stearic diethanolamide, stearic monoisopropanolamide and stearic monoethanolamide stearate.

Long chain acyl derivatives, ethylene glycol esters of long chain carboxylic acids, long chain amine oxides, and alkanol amides of long chain carboxylic acids in addition to the preferred materials listed above may be used as suspending agents. For example, it is contemplated that suspending agents with long chain hydrocarbyls having C 8 –C 22  chains may be used. 
     Other long chain acyl derivatives suitable for use as suspending agents include N,N-dihydrocarbyl amido benzoic acid and soluble salts thereof (e.g., Na, K), particularly N,N-di(hydrogenated) C 16 , C 18  and tallow amido benzoic acid species of this family, which are commercially available from Stepan Company (Northfield, Ill., USA). 
     Examples of suitable long chain amine oxides for use as suspending agents include alkyl (C 16 –C 22 ) dimethyl amine oxides, e.g., stearyl dimethyl amine oxide 
     Other suitable suspending agents include xanthan gum at concentrations ranging from about 0.3% to about 3%, preferably from about 0.4% to about 1.2%, by weight of the personal cleansing compositions. The use of xanthan gum as a suspending agent in silicone containing personal cleansing compositions is described, for example, in U.S. Pat. No. 4,788,006, which description is incorporated herein by reference. Combinations of long chain acyl derivatives and xanthan gum may also be used as a suspending agent in the personal cleansing compositions. Such combinations are described in U.S. Pat. No. 4,704,272, which description is incorporated herein by reference. 
     Other suitable suspending agents include carboxyvinyl polymers. Preferred among these polymers are the copolymers of acrylic acid crosslinked with polyallylsucrose as described in U.S. Pat. No. 2,798,053, which description is incorporated herein by reference. Examples of these polymers include Carbopol 934, 940, 941, and 956, available from B. F. Goodrich Company. 
     Other suitable suspending agents include primary amines having a fatty alkyl moiety having at least about 16 carbon atoms, examples of which include palmitamine or stearamine, and secondary amines having two fatty alkyl moieties each having at least about 12 carbon atoms, examples of which include dipalmitoylamine or di(hydrogenated tallow)amine. Still other suitable suspending agents include di(hydrogenated tallow)phthalic acid amide, and crosslinked maleic anhydride-methyl vinyl ether copolymer. 
     Other suitable suspending agents may be used in the personal cleansing compositions, including those that can impart a gel-like viscosity to the composition, such as water soluble or colloidally water soluble polymers like cellulose ethers (e.g., methylcellulose, hydroxybutyl methylcellulose, hyroxypropylcellulose, hydroxypropyl methylcellulose, hydroxyethyl ethylcellulose and hydorxethylcellulose), guar gum, polyvinyl alcohol, polyvinyl pyrrolidone, hydroxypropyl guar gum, starch and starch derivatives, and other thickeners, viscosity modifiers, gelling agents, etc. Mixtures of these materials can also be used.

Suitable conventional personal care polymers include:
         i) deposition polymers;   ii) styling polymers and solvent;   iii) dispersed phase polymers; and   iv) mixtures thereof.
 
i) Deposition Polymer—The personal cleansing compositions used in the methods of the present invention can additionally comprise an organic deposition polymer as a deposition aid. It can be present at levels of from about 0.01 to about 5%, preferably from about 0.05 to about 1%, more preferably from about 0.08% to about 0.5% by weight. The polymer may be a homopolymer or be formed from two or more types of monomers. The molecular weight of the polymer will generally be between about 25,000 and about 10,000,000, preferably between about 100,000 and about 5,000,000, more preferably in the range between about 300,000 to about 3,000,000 and most preferably from about 500,000 to about 2,000,000.

It is preferred that when the deposition polymer is present there is additionally present in the composition a hair conditioning agent, antidandruff agent, styling polymer or mixtures thereof, all of which are defined hereafter. Alternatively the deposition polymer can be used independantly, that is on its own, in the personal cleansing composition.
       

     See copending U.S. patent application Ser. Nos. 07/960,473, Ser. No. 08/738,156, filed on Oct. 25, 1996, 60/053,319, filed on Jul. 21, 1997, all of which are incorporated herein by reference, for exemplification of deposition polymers.

     Any anionic counterions can be use in association with the cationic polymers so long as the polymers remain soluble in water, in the personal cleansing composition, or in a coacervate phase of the personal cleansing composition, and so long as the counterions are physically and chemically compatible with the essential components of the personal cleansing composition or do not otherwise unduly impair product performance, stability or aesthetics. Non limiting examples of such counterions include halides (e.g., chlorine, fluorine, bromine, iodine), sulfate and methylsulfate. 
     The cationic nitrogen-containing moiety of the cationic polymer is generally present as a substituent on all, or more typically on some, of the monomer units thereof. Thus, the cationic polymer for use in the personal cleansing composition includes homopolymers, copolymers, terpolymers, and so forth, of quaternary ammonium or cationic amine-substituted monomer units, optionally in combination with non-cationic monomers referred to herein as spacer monomers. Non limiting examples of such polymers are described in the  CTFA Cosmetic Ingredient Dictionary,  3rd edition, edited by Estrin, Crosley, and Haynes, (The Cosmetic, Toiletry, and Fragrance Association, Inc., Washington, D.C. (1982)), which description is incorporated herein by reference. 
     Suitable cationic polymers include, for example, copolymers of vinyl monomers having cationic amine or quaternary ammonium functionalities with water soluble spacer monomers such as (meth)acrylamide, alkyl and dialkyl (meth)acrylamides, alkyl (meth)acrylate, vinyl caprolactone and vinyl pyrrolidine.

Other suitable spacers include vinyl esters, vinyl alcohol, maleic anhydride, propylene glycol and ethylene glycol. 
     The cationic amines can be primary, secondary or tertiary amines, depending upon the particular species and the pH of the personal cleansing. In general secondary and tertiary amines, especially tertiary, are preferred.

No. 4,009,256, incorporated herein by reference. 
     Other cationic polymers that can be used include polysaccharide polymers, such as cationic cellulose derivatives and cationic starch derivatives. Cationic polysaccharide polymer materials suitable for use herein include those of the formula: 
                         
wherein: A is an anhydroglucose residual group, such as starch or cellulose anhydroglucose residual, R is an alkylene oxyalklene, polyoxyalkylene, or hydroxyalkylene group, or combination thereof, R 1 , R 2  and R 3  independently are alkyl, aryl, alkylaryl, arylalkyl, alkoxyalkyl, or alkoxyaryl groups, each group containing up to about 18 carbon atoms, and the total number of carbon atoms for each cationic moiety (i.e., the sum of carbon atoms in R 1 , R 2  and R 3 ) preferably being about 20 or less, and X is an anionic counterion, as previously described.
 
     Cationic cellulose is available from Amerchol Corp. (Edison, N.J., USA) in their Polymer JR (trademark) and LR (trade mark) series of polymers, as salts of hydroxyethyl cellulose reacted with trimethyl ammonium substituted epoxide, referred to in the industry (CTFA) as Polyquaternium 10. Another type of cationic cellulose includes the polymeric quaternary ammonium salts of hydroxyethyl cellulose reacted with lauryl dimethyl ammonium-substituted epoxide, referred to in the industry (CTFA) as Polyquaternium 24. These materials are available from Amerchol Corp. (Edison, N.J., USA) under the tradename Polymer LM-200. 
     Other cationic polymers that can be used include cationic guar gum derivatives, such as guar hydroxypropyltrimonium chloride (commercially available from Celanese Corp. in their Jaguar trade mark series).

     The deposition polymer does not have to be soluble in the personal cleansing composition. Preferably, however, the cationic polymer is either soluble in the personal cleansing composition, or in a complex coacervate phase in the personal cleansing composition formed by the cationic polymer and anionic material. Complex coacervates of the cationic polymer can be formed with anionic surfactants or with anionic polymers that can optionally be added to the composition hereof (e.g., sodium polystyrene sulfonate). 
     Coacervate formation is dependent upon a variety of criteria such as molecular weight, concentration, and ratio of interacting ionic materials, ionic strength (including modification of ionic strength, for example, by addition of salts), charge density of the cationic and anionic species, pH, and temperature. Coacervate systems and the effect of these parameters have been described, for example, by J. Caelles, et al., “Anionic and Cationic Compounds in Mixed Systems”,  Cosmetics  &amp;  Toiletries , Vol. 106, April 1991, pp 49–54, C. J. van Oss, “Coacervation, Complex-Coacervation and Flocculation”,  J. Dispersion Science and Technology , Vol. 9 (5,6), 1988–89, pp 561–573, and D. J. Burgess, “Practical Analysis of Complex Coacervate Systems”,  J. of Colloid and Interface Science , Vol. 140, No. 1, November 1990, pp 227–238, which descriptions are incorporated herein by reference. 
     It is believe to be particularly advantageous for the cationic polymer to be present in the personal cleansing in a coacervate phase, or to form a coacervate phase upon application or rinsing of the personal cleansing to or from the hair. Complex coacervates are believed to more readily deposit on the hair. Thus, in general, it is preferred that the cationic polymer exist in the personal cleansing as a coacervate phase or form a coacervate phase upon dilution. If not already a coacervate in the personal cleansing, the cationic polymer will preferably exist in a complex coacervate form in the personal cleansing upon dilution with water to a water:personal cleansing composition rate ratio of about 20:1, more preferably at about 10:1, even more preferably at about 8:1. 
     Techniques for analysis of formation of complex coacervates are known in the art. For example, microscopic analyses of the personal cleansing compositions, at any chosen stage of dilution, can be utilized to identify whether a coacervate phase has formed. Such coacervate phase will be identifiable as an additional emulsified phase in the composition. The use of dyes can aid in distinguishing the coacervate phase from other insoluble phase dispersed in the composition. 
     Preferably the deposition polymer is selected from the group comprising cationic hydroxyalkyl cellulose ethers and cationic guar derivatives. Particularly preferred deposition polymers are Jaguar C13S, Jaguar C15, Jaguar C17 and Jaguar C16 and Jaguar C162. Other preferred cationic cellulose ethers include Polymer JR400, JR30M and JR125. 
     Surfactant soluble Conditioning Oil—The shampoo compositions used in the methods of the present invention may additionally comprise a low viscosity, surfactant soluble conditioning oil which is solubilized in the surfactant component as an additional hair conditioning agent for use in combination with the cationic hair conditioning polymer described hereinbefore. The concentration of the low viscosity, surfactant soluble oil ranges from about 0.05% to about 3%, preferably from about 0.08% to about 1.5%, more preferably from about 0.1% to about 1%, by weight of the shampoo composition. 
     The low viscosity, surfactant soluble, conditioning oils are water insoluble, water dispersible, liquids selected from the group consisting of hydrocarbon oils and fatty esters, or combinations thereof, wherein the surfactant soluble conditioning oil has a viscosity of from about 1 to about 300 centipoise, preferably from about 1 to about 150 centipoise, more preferably from about 2 to about 50 centipoise, as measured at 40° C. according to ASTM D-445. 
     It has been found that these low viscosity surfactant soluble conditioning oils provide the shampoo composition with improved conditioning performance when used in combination with the deposition polymers described herein. These surfactant soluble conditioning oils are believed to be solubilized in the surfactant micelles of the shampoo composition. It is also believed that this solubilization into the surfactant micelles contributes to the improved hair conditioning performance of the shampoo compositions herein. 
     Suitable surfactant soluble conditioning oils for use in the shampoo composition include hydrocarbon oils having at least about 10 carbon atoms, such as cyclic hydrocarbons, straight chain aliphatic hydrocarbons (saturated or unsaturated), and branched chain aliphatic hydrocarbons (saturated or unsaturated), including polymers thereof. Straight chain hydrocarbon oils preferably contain from about 12 to about 19 carbon atoms. Branched chain hydrocarbon oils, including hydrocarbon polymers, can and typically will contain more than 19 carbon atoms. Specific non limiting examples of these hydrocarbon oils include paraffin oil, mineral oil, saturated and unsaturated dodecane, saturated and unsaturated tridecane, saturated and unsaturated tetradecane, saturated and unsaturated pentadecane, saturated and unsaturated hexadecane, polybutene, polydecene, and combinations thereof. Branched-chain isomers of these compounds, as well as of higher chain length hydrocarbons, can also be used, examples of which include highly branched, saturated or unsaturated, alkanes such as the permethyl-substituted isomers, e.g., the permethyl-substituted isomers of hexadecane and eicosane, such as 2, 2, 4, 4, 6, 6, 8, 8-dimethyl-10-methylundecane and 2, 2, 4, 4, 6, 6-dimethyl-8-methylnonane, sold by Permethyl Corporation. Hydrocarbon polymers such as polybutene and polydecene, especially polybutene, can also be used. 
     Other surfactant soluble conditioning oils for use in the shampoo composition include a liquid polyolefin such as a liquid polyalphaolefin or a hydrogenated liquid polyalphaolefin. Polyolefins suitable for use in the shampoo composition herein are prepared by polymerization of olefenic monomers containing from about 4 to about 14 carbon atoms, preferably from about 6 to about 12 carbon atoms. Polyalphaolefins are preferred, and are prepared by polymerization of 1-alkene monomers having from about 4 to about 14 carbon atoms, preferably from about 6 to about 12 carbon atoms. 
     Non limiting examples of olefenic monomers for use in preparing the polyolefin liquids herein include ethylene, propylene, 1-butene, 1-pentene, 1-hexene, 1-octene, 1decene, 1-dodecene, 1-tetradecene, branched chain isomers such as 4-methyl-1-pentene, and combinations thereof. Also suitable for preparing the polyolefin liquids are olefin-containing refinery feedstocks or effluents. Preferred, however, are the hydrogenated alpha-olefin monomers having from about 4 to about 14 carbon atoms, or combinations thereof, examples of which include 1-hexene to 1-hexadecenes and combinations thereof, and preferably are 1-octene to 1-tetradecene or combinations thereof. 
     (ii) Styling polymer—The personal cleansing compositions used in the methods of the present invention may additionally contain a water-insoluble hair styling polymer, concentrations of which range from about 0.1% to about 10%, preferably from about 0.3% to about 7%, more preferably from about 0.5% to about 5%, by weight of the composition. These styling polymers provide the personal cleansing composition of the present invention with hair styling performance by providing a thin polymeric film on the hair after application from a personal cleansing composition. The polymeric film deposited on the hair has adhesive and cohesive strength, as is understood by those skilled in the art. It is essential that when a styling polymer is present in the personal cleansing compositions of the invention that a solvent, defined hereafter, is also present in the It is preferred that when a styling polymer is present a deposition polymer be also present. This combination improves deposition and retention of the styling polymer. Furthermore, it is preferd that when the personal cleansing composition contains a styling polymer it is preferred that a cationic spreading agent be present. 
     Many such polymers are known in the art, including water-insoluble organic polymers and water-insoluble silicone-grafted polymers, all of which are suitable for use in the personal cleansing composition herein provided that they also have the requisite features or characteristics described hereinafter. Such polymers can be made by conventional or otherwise known polymerization techniques well known in the art, an example of which includes free radical polymerization. 
     See copending U.S. patent application Ser. No. 08/738,211, filed on Oct. 25, 1996 and Ser. No. 60/053,319, filed on Oct. 25, 1996 both of which are incorporated herein by reference. 
     Examples of suitable organic and silicone grafted polymers for use in the personal cleansing composition of the present invention are described in greater detail hereinafter. 
     Organic styling polymer—The styling polymers suitable for use in the methods of the present invention include organic styling polymers well known in the art. The organic styling polymers may be homopolymers, copolymers, terpolymers or other higher polymers, but must comprise one or more polymerizable hydrophobic monomers to thus render the resulting styling polymer hydrophobic and water-insoluble as defined herein. The styling polymers may therefore further comprise other water soluble, hydrophilic monomers provided that the resulting styling polymers have the requisite hydrophobicity and water insolubility. 
     As used herein, the term “hydrophobic monomer” refers to polymerizable organic monomers that can form with like monomers a water-insoluble homopolymer, and the term “hydrophilic monomer” refers to polymerizable organic monomers that can form with like monomers a water-soluble homopolymer. 
     The organic styling polymers preferably have a weight average molecular weight of at least about 20,000, preferably greater than about 25,000, more preferably greater than about 30,000, most preferably greater than about 35,000. There is no upper limit for molecular weight except that which limits applicability of the invention for practical reasons, such as processing, aesthetic characteristics, formulateability, etc. In general, the weight average molecular weight will be less than about 10,000,000, more generally less than about 5,000,000, and typically less than about 2,000,000.

     The organic styling polymers also preferably have a glass transition temperature (Tg) or crystalline melting point (Tm) of at least about −20° C., preferably from about 20° C. to about 80° C., more preferably from about 20° C. to about 60° C. Styling polymers having these Tg or Tm values form styling films on hair that are not unduly sticky or tacky to the touch. As used herein, the abbreviation “Tg” refers to the glass transition temperature of the backbone of the polymer, and the abbreviation “Tm” refers to the crystalline melting point of the backbone, if such a transition exists for a given polymer. Preferably, both the Tg and the Tm, if any, are within the ranges recited hereinabove. 
     The organic styling polymers are carbon chains derived from polymerization of hydrophobic monomers such as ethylenically unsaturated monomers, cellulosic chains or other carbohydrate-derived polymeric chains. The backbone may comprise ether groups, ester groups, amide groups, urethanes, combinations thereof, and the like. 
     The organic styling polymers may further comprise one or more hydrophilic monomers in combination with the hydrophobic monomers described herein, provided that the resulting styling polymer has the requisite hydrophobic character and water-insolubility. Suitable hydrophilic monomers include, but are not limited to, acrylic acid, methacrylic acid, N,N-dimethylacrylamide, dimethyl aminoethyl methacrylate, quaternized dimethylaminoethyl methacrylate, methacrylamide, N-t-butyl acrylamide, maleic acid, maleic anhydride and its half esters, crotonic acid, itaconic acid, acrylamide, acrylate alcohols, hydroxyethyl methacrylate, diallyldimethyl ammonium chloride, vinyl pyrrolidone, vinyl ethers (such as methyl vinyl ether), maleimides, vinyl pyridine, vinyl imidazole, other polar vinyl heterocyclics, styrene sulfonate, allyl alcohol, vinyl alcohol (such as that produced by the hydrolysis of vinyl acetate after polymerization), salts of any acids and amines listed above, and mixtures thereof. Preferred hydrophilic monomers include acrylic acid, N,N-dimethyl acrylamide, dimethylaminoethyl methacrylate, quaternized dimethyl aminoethyl methacrylate, vinyl pyrrolidone, salts of acids and amines listed above, and combinations thereof. 
     Suitable hydrophobic monomers for use in the organic styling polymer include, but are not limited to, acrylic or methacrylic acid esters of C 1 –C 18  alcohols, such as methanol, ethanol, methoxy ethanol, 1-propanol, 2-propanol, 1-butanol, 2-methyl-1-propanol, 1-pentanol, 2-pentanol, 3-pentanol, 2-methyl-1-butanol, 1-methyl-1-butanol, 3-methyl-1-butanol, 1-methyl-1-pentanol, 2-methyl-1-pentanol, 3-methyl-1-pentanol, t-butanol(2-methyl-2-propanol), cyclohexanol, neodecanol, 2-ethyl-1-butanol, 3-heptanol, benzyl alcohol, 2-octanol, 6-methyl-1-heptanol, 2-ethyl-1-hexanol, 3,5-dimethyl-1-hexanol, 3,5,5-tri methyl-1-hexanol, 1-decanol, 1-dodecanol, 1-hexadecanol, 1-octa decanol, and the like, the alcohols having from about 1 to about 18 carbon atoms, preferably from about 1 to about 12 carbon atoms; styrene; polystyrene macromer; vinyl acetate; vinyl chloride; vinylidene chloride; vinyl propionate; alpha-methylstyrene; t-butylstyrene; butadiene; cyclohexadiene; ethylene; propylene; vinyl toluene; and mixtures thereof.

The particular selection and combination of monomers for incorporation into the styling polymer will help determine its formulational properties. By appropriate selection and combination of, for example, hydrophilic and hydrophobic monomers, the styling polymer can be optimized for physical and chemical compatibility with the selected styling polymer solvent described hereinafter and other components of the personal cleansing composition. The selected monomer composition of the organic styling polymer must, however, render the styling polymer water-insoluble but may be soluble in the selected solvent described hereinafter. In this context, the organic styling polymer is soluble in the solvent if the organic polymer is solubilized in the solvent at 25° C. at the polymer and solvent concentrations of the personal cleansing formulation selected. However, a solution of the organic styling polymer and solvent may be heated to speed up solubility of the styling polymer in the solvent. Such styling polymer and solvent formulation, including the selection of monomers for use in the styling polymer, to achieve the desired solubility is well within the skill of one in the art.

No. 5,120,532, to Wells et al., issued Jun. 9, 1992; U.S. Pat. No. 5,104,642, to Wells et al., issued Apr. 14, 1992; U.S. Pat. No. 4,272,511, to Papantoniou et al., issued Jun. 9, 1981; U.S. Pat. No. 4,963,348, to Bolich et al., issued Oct. 16, 1990 and U.S. Pat. No. 4,196,190, to Gehman et al., issued Apr. 1, 1980, which descriptions are incorporated herein by reference. 
     Silicone-grafted styling polymer—Other suitable styling polymers for use in the methods of the present invention are silicone-grafted hair styling resins. These polymers may be used alone or in combination with the organic styling polymers described hereinbefore. Many such polymers suitable for use in the personal cleansing composition herein are known in the art. These polymers are characterized by polysiloxane moieties covalently bonded to and pendant from a polymeric carbon-based backbone. 
     The backbone of the silicone-grafted polymer is preferably a carbon chain derived from polymerization of ethylenically unsaturated monomers, but can also be cellulosic chains or other carbohydrate-derived polymeric chains to which polysiloxane moieties are pendant. The backbone can also include ether groups, ester groups, amide groups, urethane groups and the like. The polysiloxane moieties can be substituted on the polymer or can be made by co-polymerization of polysiloxane-containing polymerizable monomers (e.g. ethylenically unsaturated monomers, ethers, and/or epoxides) with non-polysiloxane-containing polymerizable monomers. 
     The silicone-grafted styling polymers for use in the personal cleansing composition comprise “silicone-containing” (or “polysiloxane-containing”) monomers, which form the silicone macromer pendant from the backbone, and non-silicone-containing monomers, which form the organic backbone of the polymer. That is a siloxane monomer grafted to the hair styling polymer. 
     Preferred silicone-grafted polymers comprise an organic backbone, preferably a carbon backbone derived from ethylenically unsaturated monomers, such as a vinyl polymeric backbone, and a polysiloxane macromer (especially preferred are polydialkylsiloxane, most preferably polydimethylsiloxane) grafted to the backbone. The polysiloxane macromer should have a weight average molecular weight of at least about 500, preferably from about 1,000 to about 100,000, more preferably from about 2,000 to about 50,000, most preferably about 5,000 to about 20,000. Organic backbones contemplated include those that are derived from polymerizable, ethylenically unsaturated monomers, including vinyl monomers, and other condensation monomers (e.g., those that polymerize to form polyamides and polyesters), ring-opening monomers (e.g., ethyl oxazoline and caprolactone), etc. Also contemplated are backbones based on cellulosic chains, ether-containing backbones, etc. 
     Preferred silicone grafted polymers for use in the personal cleansing composition comprise monomer units derived from: at least one free radically polymerizable ethylenically unsaturated monomer or monomers and at least one free radically polymerizable polysiloxane-containing ethylenically unsaturated monomer or monomers. 
     The silicone grafted polymers suitable for use in the personal cleansing composition generally comprise from about 1% to about 50%, by weight, of polysiloxane-containing monomer units and from about 50% to about 99% by weight, of non-polysiloxane-containing monomers. The non-polysiloxane-containing monomer units can be derived from the hydrophilic and/or hydrophobic monomer units described hereinbefore. 
     The styling polymer for use in the personal cleansing composition can therefore comprise combinations of the hydrophobic and/or polysiloxane-containing monomer units described herein, with or without hydrophilic comonomers as described herein, provided that the resulting styling polymer has the requisite characteristics as described herein. 
     Suitable polymerizable polysiloxane-containing monomers include, but are not limited to, those monomers that conform to the formula:

These polymerizable polysiloxane-containing monomers have a weight average molecular weight as described above.
 
     A preferred polysiloxane-containing monomer conforms to the formula:

wherein R 2  is hydrogen or —COOH (preferably R 2  is hydrogen); R 3  is hydrogen, methyl or —CH 2 COOH (preferably R 3  is methyl); Z conforms to the formula:
 
                         
wherein R 4 , R 5 , and R 6  independently are lower alkyl, alkoxy, alkylamino, aryl, arylalkyl, hydrogen or hydroxyl (preferably R 4 , R 5 , and R 6  are alkyls); and r is an integer of about 5 or higher, preferably about 10 to about 1500 (most preferably r is from about 100 to about 250). Most preferably, R 4 , R 5 , and R 6  are methyl, p=0, and q=3.
 
     Another preferred polysiloxane monomer conforms to either of the following formulas

     The silicone grafted styling polymers suitable for use in the personal cleansing composition preferably comprise from about 50% to about 99%, more preferably from about 60% to about 98%, most preferably from about 75% to about 95%, by weight of the polymer, of non-silicone macromer-containing monomer units, e.g. the total hydrophobic and hydrophilic monomer units described herein, and from about 1% to about 50%, preferably from about 2% to about 40%, more preferably from about 5% to about 25%, of silicone macromer-containing monomer units, e.g. the polysiloxane-containing monomer units described herein. The level of hydrophilic monomer units can be from about 0% to about 70%, preferably from about 0% to about 50%, more preferably from about 0% to about 30%, most preferably from about 0% to about 15%; the level of hydrophobic monomer units, can be from 30% to about 99%, preferably from about 50% to about 98%, more preferably from about 70% to about 95%, most preferably from about 85% to about 95%.

     Examples of other suitable silicone grafted polymers for use in the personal cleansing composition of the present invention are described in EPO Application 90307528.1, published as EPO Application 0 408 311 A2 on Jan. 11, 1991, Hayama, et al.; U.S. Pat. No. 5,061,481, issued Oct. 29, 1991, Suzuki et al.; U.S. Pat. No. 5,106,609, Bolich et al., issued Apr. 21, 1992; U.S. Pat. No. 5,100,658, Bolich et al., issued Mar. 31, 1992; U.S. Pat. No. 5,100,657, Ansher-Jackson, et al., issued Mar. 31, 1992; U.S. Pat. No. 5,104,646, Bolich et al., issued Apr. 14, 1992; U.S. Ser. No. 07/758,319, Bolich et al, filed Aug. 27, 1991, U.S. Ser. No. 07/758,320, Torgerson et al., filed Aug. 27, 1991, which descriptions are incorporated herein by reference. 
     Solvent—The personal cleansing composition used in the methods of the present invention must additionally comprise a volatile solvent for solubilizing the styling polymers, described hereinbefore, when such a styling polymer is present. The solvent helps disperse the styling polymer as water-insoluble fluid particles throughout the personal cleansing composition, wherein the dispersed particles comprise the styling polymer and the volatile solvent. Solvents suitable for this purpose include hydrocarbons, ethers, esters, amines, alkyl alcohols, volatile silicone derivatives and combinations thereof, many examples of which are well known in the art. 
     The volatile solvent must be water-insoluble or have a low water solubility. The selected styling polymer, however, must also be sufficiently soluble in the selected solvent to allow dispersion of the hair styling polymer and solvent combination as a separate, dispersed fluid phase in the personal cleansing composition. 
     The solvent suitable for use in the personal cleansing composition must also be a volatile material. In this context, the term volatile means that the solvent has a boiling point of less than about 300° C., preferably from about 90° C. to about 260° C., more preferably from about 100° C. to about 200° C. (at about one atmosphere of pressure). 
     The concentration of the volatile solvent in the personal cleansing composition must be sufficient to solubilize the hair styling polymer and disperse it as a separate fluid phase in the personal cleansing composition. Such concentrations generally range from about 0.10% to about 10%, preferably from about 0.5% to about 8%, most preferably from about 1% to about 6%, by weight of the personal cleansing composition, wherein the weight ratio of styling polymer to solvent is preferably from about 10:90 to about 70:30, more preferably from about 20:80 to about 65:35, even more preferably from about 30:70 to about 60:40. If the weight ratio of styling polymer to solvent is too low, the lathering performance of the personal cleansing composition is negatively affected. If the ratio of polymer to solvent is too high, the composition becomes too viscous and causes difficulty in the dispersion of the styling polymer. The hair styling agents should have an average particle diameter in the final personal cleansing product of from about 0.05 to about 100 microns, preferably from about 0.2 micron to about 25 microns. Particle size can be measured according to methods known in the art, including, for example optical microscopy. 
     Preferred volatile solvents for use in the personal cleansing composition are the hydrocarbon solvents, especially branched chain hydrocarbon solvents. The hydrocarbon solvents may be linear or branched, saturated or unsaturated, hydrocarbons having from about 8 to about 18 carbon atoms, preferably from about 10 to about 16 carbon atoms. Saturated hydrocarbons are preferred, as are branched hydrocarbons. Nonlimiting examples of some suitable linear hydrocarbons include decane, dodecane, decene, tridecene, and combinations thereof. Suitable branched hydrocarbons include isoparaffins, examples of which include commercially available isoparaffins from Exxon Chemical Company such as Isopar H and K (C 1 –C 12  isoparaffins), and Isopar L (C 11 –C 13  isoparaffins). Preferred branched hydrocarbons are isohexadecane, isododecane, 2,5-dimethyl decane, isotetradecane, and combinations thereof. Commercially available branched hydrocarbons include Permethyl 99A and 101A (available from Preperse, Inc., South Plainfield, N.J., USA). 
     Other suitable solvents include isopropanol, butyl alcohol, amyl alcohol, phenyl ethanol, benzyl alcohol, phenyl propanol, ethyl butyrate, isopropyl butyrate, diethyl phthalate, diethyl malonate, diethyl succinate, dimethyl malonate, dimethyl succinate, phenyl ethyl dimethyl carbinol, ethyl-6-acetoxyhexanoate, and methyl (2-pentanyl-3-oxy)cyclopentylacetate, and mixtures thereof. Preferred among such other suitable solvents are diethyl phthalate, diethyl malonate, diethyl succinate, dimethyl malonate, dimethyl succinate, phenylethyl dimethyl carbinol, ethyl-6-acetoxyhexanoate, and mixtures thereof.

The alcohols can be derived from fats, e.g., coconut oil or tallow, or can be synthetic. Lauryl alcohol and straight chain alcohols derived from coconut oil are preferred herein. Such alcohols are reacted with between about 0 and about 10, and especially about 3, molar proportions of ethylene oxide and the resulting mixture of molecular species having, for example, an average of 3 moles of ethylene oxide per mole of alcohol, is sulfated and neutralized. 
     Specific examples of alkyl ether sulfates which may be used in the personal cleansing compositions of the present invention are sodium and ammonium salts of coconut alkyl triethylene glycol ether sulfate; tallow alkyl triethylene glycol ether sulfate, and tallow alkyl hexaoxyethylene sulfate. Highly preferred alkyl ether sulfates are those comprising a mixture of individual compounds, said mixture having an average alkyl chain length of from about 10 to about 16 carbon atoms and an average degree of ethoxylation of from about 1 to about 4 moles of ethylene oxide. 
     Other suitable anionic co-surfactants are the water-soluble salts of organic, sulfuric acid reaction products of the general formula [R 1 —SO 3 -M] where R 1  is selected from the group consisting of a straight or branched chain, saturated aliphatic hydrocarbon radical having from about 8 to about 24, preferably about 10 to about 18, carbon atoms; and M is a cation, as previously described, subject to the same limitations regarding polyvalent metal cations as previously discussed. Examples of such co-surfactants are the salts of an organic sulfuric acid reaction product of a hydrocarbon of the methane series, including iso-, neo-, and n-paraffins, having about 8 to about 24 carbon atoms, preferably about 12 to about 18 carbon atoms and a sulfonating agent, e.g., SO 3 , H 2 SO 4 , obtained according to known sulfonation methods, including bleaching and hydrolysis.

The sulfur trioxide can be liquid or gaseous, and is usually, but not necessarily, diluted by inert diluents, for example by liquid SO 2 , chlorinated hydrocarbons, etc., when used in the liquid form, or by air, nitrogen, gaseous SO 2 , etc., when used in the gaseous form. 
     The alpha-olefins from which the olefin sulfonates are derived are mono-olefins having about 12 to about 24 carbon atoms, preferably about 14 to about 16 carbon atoms. Preferably, they are straight chain olefins. 
     In addition to the true alkene sulfonates and a proportion of hydroxy-alkanesulfonates, the olefin sulfonates can contain minor amounts of other materials, such as alkene disulfonates depending upon the reaction conditions, proportion of reactants, the nature of the starting olefins and impurities in the olefin stock and side reactions during the sulfonation process.

     The alkyl portion of said ABS or LAS surfactant preferably contains from 10 to 16 carbon atoms, more preferably from 10 to 14 carbon atoms. Most preferably, the alkylbenzene sulfonate surfactant is LAS. 
     The alkyl portion of the AS surfactant preferably contains from 10 to 18 carbon atoms, more preferably from 12 to 16 carbon atoms. The AS surfactant can comprise a mixture of a longer-chain AS, such as one having 16 to 18 carbons, and a shorter-chain alkyl such as one having 11–13 carbons.

These detergent builders can be, for example, water-soluble alkali-metal salts of phosphates, pyrophosphates, orthophosphates, tripolyphosphates, higher polyphosphates, and mixtures thereof. A preferred builder is a water-soluble alkali-metal salt of tripolyphosphate, and a mixture of tripolyphosphate and pyrophosphate. The builder can also be a non-phosphate detergent builder. Specific examples of a non-phosphorous, inorganic detergency builder include water-soluble inorganic carbonate and bicarbonate salts. The alkali metal (e.g., sodium and potassium) carbonates, bicarbonates, and silicates are particularly useful herein. Specific preferred examples of builders include sodium tripolyphosphates (STPP) and sodium pyrophosphates (TSPP), and mixtures thereof. Other specifically preferred examples of builders include zeolite and polycarboxylates. 
     Sodium carbonate is a particularly preferred ingredient in laundry bars, since in addition to its use as a builder, it can also provide alkalinity to the laundry bar for improved detergency, and also can serve as a neutralizing agent for acidic components added in the bar processing. Sodium carbonate is particularly preferred as a neutralizing inorganic salt for an acid precursor of an anionic surfactant used in such laundry bars, such as the alkyl sulfuric acid and alkyl benzene sulfonic acid. 
     Co-polymers of acrylic acid and maleic acid are preferred as auxiliary builders, since it has been observed that their use in combination with the fabric softening clay and the clay flocculating agent further stabilizes and improves the clay deposition and fabric softening performance.

Preferably, the hydrotrope, in either the acid form or the salt form, and being substantially anhydrous, is added to the linear alkyl benzene sulfonic acid prior to its neutralization. The hydrotrope will preferably be present at from about 0.5% to about 5% of the laundry detergent bar. 
     Fabric Softening Clay—The fabric softening clay is preferably a smectite-type clay. The smectite-type clays can be described as expandable, three-layer clays; i.e., alumino-silicates and magnesium silicates, having an ion exchange capacity of at least about 50 meq/100 g. of clay. Preferably the clay particles are of a size that they can not be perceived tactilely, so as not to have a gritty feel on the treated fabric of the clothes. The fabric softening clay can be added to the bar to provide about 1% to about 30% by weight of the bar, more preferably from about 5% to about 20%, and most preferably about 8% to 14%. 
     While any of the smectite-type clays described herein are useful in the present invention, certain clays are preferred. For example, Gelwhite GP is an extremely white form of smectite-type clay and is therefore preferred when formulating white granular detergent compositions. Volclay BC, which is a smectite-type clay mineral containing at least 3% iron (expressed as Fe 2 O 3 ) in the crystal lattice, and which has a very high ion exchange capacity, is one of the most efficient and effective clays for use in the instant compositions from the standpoint of product performance. On the other hand, certain smectite-type clays are sufficiently contaminated by other silicate minerals that their ion exchange capacities fall below the requisite range; such clays are of no use in the instant compositions. 
     Clay Flocculating Agent—It has been found that the use of a clay flocculating agent in a laundry bar containing softening clay provides surprisingly improved softening clay deposition onto the clothes and clothes softening performance, compared to that of laundry bars comprising softening clay alone. The polymeric clay flocculating agent is selected to provide improved deposition of the fabric softening clay. Typically such materials have a high molecular weight, greater than about 100,000. Examples of such materials can include long chain polymers and copolymers derived from monomers such as ethylene oxide, acrylamide, acrylic acid, dimethylamino ethyl methacrylate, vinyl alcohol, vinyl pyrrolidone, and ethylene imine. Gums, like guar gums, are suitable as well. The preferred clay flocculating agent is a poly(ethylene oxide) polymer.
 
Other Optional Ingredients—A particularly preferred optional component of the laundry bars used in the methods present invention is a detergent chelant. Such chelants are able to sequester and chelate alkali cations (such as sodium, lithium and potassium), alkali metal earth cations (such as magnesium and calcium), and most preferably, heavy metal cations such as iron, manganese, zinc and aluminum. Preferred cations include sodium, magnesium, zinc, and mixtures thereof. The detergent chelant is particularly beneficial for maintaining good cleaning performance and improved surfactant mileage, despite the presence of the softening clay and the clay flocculating agent.
 
     The detergent chelant is preferably a phosphonate chelant, particular one selected from the group consisting of diethylenetriamine penta(methylene phosphonic acid), ethylene diamine tetra(methylene phosphonic acid), and mixtures and salts and complexes thereof, and an acetate chelant, particularly one selected from the group consisting of diethylenetriamine penta(acetic acid), ethylene diamine tetra(acetic acid), and mixtures and salts and complexes thereof. Particularly preferred are sodium, zinc, magnesium, and aluminum salts and complexes of diethylenetriamine penta(methylene phosphonate) diethylenetriamine penta (acetate), and mixtures thereof. 
     Preferably such salts or complexes have a molar ratio of metal ion to chelant molecule of at least 1:1, preferably at least 2:1. 
     The detergent chelant can be included in the laundry bar at a level up to about 5%, preferably from about 0.1% to about 3%, more preferably from about 0.2% to about 2%, most preferably from about 0.5% to about 1.0%. Such detergent chelant component can be used beneficially to improve the surfactant mileage of the present laundry bar, meaning that for a given level of anionic surfactant and level of detergent chelant, equivalent sudsing and cleaning performance can be achieved compared to a similar bar containing a higher level of the anionic surfactant but without the detergent chelant. 
     Another preferred additional component of the laundry bar is fatty alcohol having an alkyl chain of 8 to 22 carbon atoms, more preferably from 12 to 18 carbon atoms. Fatty alcohol is effective at reducing the bar wear rate and smear (mushiness) of the present laundry bars. A preferred fatty alcohol has an alkyl chain predominantly containing from 16 to 18 carbon atoms, so-called “high-cut fatty alcohol,” which can exhibit less base odor of fatty alcohol relative to broad cut fatty alcohols. Typically fatty alcohol is contained in the laundry bar at up to a level of 10%, more preferably from about 0.75% to about 6%, most preferably from about 2% to about 5%. The fatty alcohol is generally added to the formulation of the present invention as free fatty alcohol. However, low levels of fatty alcohol can be introduced into the bars as impurities or as unreacted starting material. For example, laundry bars based on coconut fatty alkyl sulfate can contain, as unreacted starting material, from 0.1% to 3.5%, more typically from 2% to 3%, by weight of free coconut fatty alcohol on a coconut fatty alkyl sulfate basis. 
     Another preferred optional component in the laundry bar is a dye transfer inhibiting (DTI) ingredient to prevent diminishing of color fidelity and intensity in fabrics. A preferred DTI ingredient can include polymeric DTI materials capable of binding fugitives dyes to prevent them from depositing on the fabrics, and decolorization DTI materials capable of decolorizing the fugitives dye by oxidation. An example of a decolorization DTI is hydrogen peroxide or a source of hydrogen peroxide, such as percarbonate or perborate. Non-limiting examples of polymeric DTI materials include polyvinylpyrridine N-oxide, polyvinylpyrrolidone (PVP), PVP-polyvinylimidazole copolymer, and mixtures thereof. Copolymers of N-vinylpyrrolidone and N-vinylimidazole polymers (referred to as “PVPI”) are also preferred for use herein. 
     Another preferred optional component in the laundry bar is a secondary fabric softener component in addition to the softening clay. Such materials can be used at levels of about 0.1% to 5%, more preferably from 0.3% to 3%, and can include: amines of the formula R 4 R 5 R 6 N, wherein R 4  is C5 to C 22  hydrocarbyl, R 5  and R 6  are independently C 1  to C 10  hydrocarbyl. One preferred amine is ditallowmethyl amine; complexes of such amines with fatty acid of the formula R 7 COOH, wherein R 7  is C 9  to C 22  hydrocarbyl, as disclosed in EP No. 0,133,804; complexes of such amines with phosphate esters of the formula R 8 O—P(O)(OH)—OR 9  and HO—P(O)(OH)—OR 9 , wherein R 8  and R 9  are independently C 1  to C 20  alkyl of alkyl ethoxylate of the formula -alkyl-(OCH 2 CH 2 ); cyclic amines such as imidazolines of the general formula 1-(higher alkyl) amido (lower alkyl)-2-(higher alkyl)imidazoline, where higher alkyl is from 12 to 22 carbons and lower alkyl is from 1 to 4 carbons, such as described in UK Patent Application GB 2,173,827; and quaternary ammonium compounds of the formula R 10 R 11 R 12 R 13 N + X − , wherein R 10  is alkyl having 8 to 20 carbons, R 11  is alkyl having 1 to 10 carbons, R 12  and R 13  are alkyl having 1 to 4 carbons, preferably methyl, and X is an anion, preferably Cl −  or Br − , such as C 12-13  alkyl trimethyl ammonium chloride. 
     Yet another optional component in the laundry bar is a bleach component. The bleaching component can be a source of  − OOH group, such as sodium perborate monohydrate, sodium perborate tetrahydrate and sodium percarbonate. Sodium percarbonate (2Na 2 CO 3 .3H 2 O 2 ) is preferred since it has a dual function of both a source of HOOH and a source of sodium carbonate. 
     Another optional bleaching component is a peracid per se, such as a formula:
 
CH 3 (CH 2 ) w —NH—C(O)—(CH 2 ) z CO 3 H
 
wherein z is from 2 to 4 and w is from 4 to 10. (The compound of the latter formula where z is 4 and w is 8 is hereinafter referred to as NAPAA.) The bleaching component can contain, as a bleaching component stabilizer, a chelating agent of polyaminocarboxylic acids, polyaminocarboxylates such as ethylenediaminotetraacetic acid, diethylenetriaminopentaacetic acid, and ethylenediaminodisuccinic acid, and their salts with water-soluble alkali metals. The bleach components can be added to the bar at a level up to 20%, preferably from about 1% to about 10%, more preferably from about 2% to about 6%.
 
     Sodium sulfate is a well-known filler that is compatible with the compositions of this invention. It can be a by-product of the surfactant sulfation and sulfonation processes, or it can be added separately. 
     Calcium carbonate (also known as Calcarb) is also a well known and often used component of laundry bars. Such materials are typically used at levels up to 40%, preferably from about 5% to about 25%. 
     Binding agents for holding the bar together in a cohesive, soluble form can also be used, and include natural and synthetic starches, gums, thickeners, and mixtures thereof. 
     Soil suspending agents can be used. In the present invention, their use is balanced with the fabric softening clay/clay flocculating agent combination to provide optimum cleaning and fabric softening performance. Soil suspending agents can also include water-soluble salts of carboxymethylcellulose and carboxyhydroxymethylcellulose. A preferred soil suspending agent is an acrylic/maleic copolymer, commercially available as Sokolan®, from BASF Corp. Other soil suspending agents include polyethylene glycols having a molecular weight of about 400 to 10,000, and ethoxylated mono- and polyamines, and quaternary salts thereof. 
     Optical brighteners are also preferred optional ingredients in laundry bars of the present invention. Preferred optical brighteners are diamino stilbene, distyrilbiphenyl-type optical brighteners. Preferred as examples of such brighteners are 4,4′-bis{[4-anilino-6-bis(2-hydoxyethyl) amino-1,3,5-trizin-2-yl]amino} stilbene-2,2′-disulfonic acid disodium salt, 4-4′-bis(2-sulfostyryl) biphenyl and 4,4′-bis[(4-anilino-6-morpholino-1,3,5-triazin-2-yl) amino]stilbene-2,2′-disulfonic acid disodium salt. Such optical brighteners, or mixtures thereof, can be used at levels in the bar of from about 0.05%–1.0%. 
     Dyes, pigments, germicides, and perfumes can also be added to the bar composition. 
     Processing—The detergent laundry bars used in the methods of the present invention can be processed in conventional soap or detergent bar making equipment with some or all of the following key equipment: blender/mixer, mill or refining plodder, two-stage vacuum plodder, logo printer/cutter, cooling tunnel and wrapper. 
     In a typical process, the raw materials are mixed in the blender. Alkylbenzene sulfonic acid (when used) is added into a mixture of alkaline inorganic salts (preferably which includes sodium carbonate) and the resulting partially neutralized mixture is mechanically worked to effect homogeneity and complete neutralization of the mixture. Once the neutralization reaction is completed, the alkyl sulfate surfactant is added, followed by the remaining other ingredient materials. The mixing can take from 1 minute to 1 hour, with the usual mixing time being from 2 to 20 minutes. The blender mix is discharged to a surge tank. The product is conveyed from the surge tank to the mill or refining plodder via a multi-worn transfer conveyor. 
     The alkyl benzene sulfonic acid (HLAS) can be made by well-known processes, such as with SO 3  or oleum. It can be preferably to include excess inorganic sulfuric acid (H 2 SO 4 ) in the stock of HLAS, which, upon neutralization, helps to increase the temperature of the product due to the heat of neutralization of the inorganic sulfuric acid. 
     After milling or preliminary plodding, the product is then conveyed to a double stage vacuum plodder, operating at a high vacuum, e.g. 600 to 740 millimeters of mercury vacuum, so that entrapped air is removed. The product is extruded and cut to the desired bar length, and printed with the product brand name. The printed bar can be cooled, for example in a cooling tunnel, before it is wrapped, cased, and sent to storage.

     Example 11 
     Preparation of LAS Powder for Use as a Structurant 
     Sodium C 12  linear alkyl benzene sulfonate (NaLAS) is processed into a powder containing two phases. One of these phases is soluble in the non-aqueous liquid detergent compositions herein and the other phase is insoluble. It is the insoluble fraction which serves to add structure and particle suspending capability to the non-aqueous phase of the compositions herein. 
     NaLAS powder is produced by taking a slurry of NaLAS in water (approximately 40–50% active) combined with dissolved sodium sulfate (3–15%) and hydrotrope, sodium sulfosuccinate (1–3%). The hydrotrope and sulfate are used to improve the characteristics of the dry powder. A drum dryer is used to dry the slurry into a flake. When the NaLAS is dried with the sodium sulfate, two distinct phases are created within the flake. The insoluble phase creates a network structure of aggregate small particles (0.4–2 um) which allows the finished non-aqueous detergent product to stably suspend solids. 
     The NaLAS powder prepared according to this example has the following makeup shown below.

The composition can provide excellent in-use hair cleaning and conditioning.
 
The example compositions hereof can be made by preparing a premix of the entire amount of silicone conditioning agent to be incorporated into the personal cleansing, along with sufficient ammonium sulfate and cetyl and stearyl alcohol such that the premix comprises about 30% silicone conditioning agent, about 69% surfactant, and about 1% of the alcohols. The premix ingredients are heated and stirred at 72° C. for about 10 minutes and the premix is then conventionally mixed with the remaining hot (72° C.) ingredients. The composition is then pumped through a high shear mixer and cooled.
 
     Example 29 
     The following examples, (L to Z), further describe and demonstrate embodiments within the scope of the present invention. The examples are given solely for the purpose of illustration and are not to be construed as limitations of the present invention, as many variations thereof are possible without departing from the spirit and scope of the invention. These exemplified embodiments of the shampoo compositions of the present invention provide cleansing of hair and improved hair conditioning performance. Ingredients are hereinafter identified by chemical, trade, or CTFA name. 
     Preparation The shampoo compositions of the present invention can be prepared by using conventional mixing and formulating techniques. The shampoo compositions illustrated hereinafter in Examples L to Z are prepared in the following manner. 
     About one-third to all of the total sulfate surfactant (added as a 25% solution) is added to a jacketed mix tank and heated to about 74° C. with slow agitation to form a surfactant solution. Cocamide MEA and fatty alcohol, as applicable, are added to the tank and allowed to disperse. Ethylene glycol distearate (EGDS), as applicable, is then added to the mixing vessel, and melted. After the EGDS is well dispersed (usually about 5 to 20 minutes) polyethylene glycol and the preservative, if used are added and mixed into the surfactant solution. This mixture is passed through a heat exchanger where it is cooled to about 35° C. and collected in a finishing tank. As a result of this cooling step, the ethylene glycol distearate crystallizes to form a crystalline network in the product. The remainder of the surfactant and other ingredients including the silicone emulsions are added to the finishing tank with ample agitation to insure a homogeneous mixture. A sufficient amount of the silicone emulsions are added to provide the desired level of dimethicone in the final product. Water dispersible polymers are typically dispersed in water as a 1% to 10% solution before addition to the final mix. Once all ingredients have been added, ammonium xylene sulfonate or additional sodium chloride can be added to the mixture to thin or thicken respectively to achieve a desired product viscosity. Preferred viscosities range from about 2500 to about 9000 cS at 25° C. (as measured by a Wells-Brookfield cone and plate viscometer at 15/s).

     In preparing each of the compositions described in Examples DD to TT, about one-third of the surfactant (added as 25 wt % solution) is added to a jacketed mix tank and heated to about 74° C. with slow agitation to form a surfactant solution. Salts (sodium chloride) and pH modifiers (disodium phosphate, monosodium phosphate) are added to the tank and allowed to disperse. Ethylene glycol distearate (EGDS) is added to the mixing vessel and allowed to melt. After the EGDS is melted and dispersed (e.g., after about 5–20 minutes), preservative and additional viscosity modifier are added to the surfactant solution. The resulting mixture is passed through a heat exchanger where it is cooled to about 35° C. and collected in a finishing tank. As a result of this cooling step, the EGDS crystallizes to form a crystalline network in the product. The remainder of the surfactant and other components are added to the finishing tank with agitation to ensure a homogeneous mixture. Cationic guar polymer is dispersed in water as a 0.5–2.5% aqueous solution before addition to the final mix. Once all components have been added, viscosity and pH modifiers are added to the mixture to adjust product viscosity and pH to the extent desired. 
     Each exemplified composition provides excellent hair cleansing, lathering, antimicrobial agent deposition on the scalp and dandruff control.

     In preparing each of the compositions described in (A to C), from 50% to 100% by weight of the detersive surfactants are added to a jacketed mix tank and heated to about 74° C. with slow agitation to form a surfactant solution. If used, pH modifiers (monosodium phosphate, disodium phosphate) are added to the tank and allowed to disperse. Ethylene glycol distearate (EGDS) and fatty alcohols (cetyl alcohol, stearyl alcohol) are then added to the mixing vessel and allowed to melt. After the EGDS is melted and dispersed (usually about 5–10 minutes), preservative (if used) is added and mixed into the surfactant solution. Additional viscosity modifier are added to the surfactant solution if necessary. The resulting mixture is passed through a heat exchanger where it is cooled to about 35° C. and collected in a finishing tank. As a result of this cooling step, the EGDS crystallizes to form a crystalline network in the product. Any remaining surfactant and other components are added to the finishing tank with agitation to ensure a homogeneous mixture. Cationic guar polymer is dispersed in water as a 0.5–2.5% aqueous solution before addition to the final mix. Once all components have been added, viscosity and pH modifiers are added to the mixture to adjust product viscosity and pH to the extent desired. 
     Each exemplified composition provides excellent hair cleansing, lathering, antimicrobial agent deposition on the scalp, and dandruff control.

     Example 34 
     The compositions of the present invention, in general, can be made by mixing together at elevated temperature, e.g., about 72° C. water and surfactants along with any solids (e.g., amphiphiles) that need to be melted, to speed mixing into the personal cleansing composition. Additional ingredients including the electrolytes can be added either to this hot premix or after cooling the premix. The nonionic or anionic polymers can be added as a water solution after cooling the premix. The ingredients are mixed thoroughly at the elevated temperature and then pumped through a high shear mill and then through a heat exchanger to cool them to ambient temperature. The silicone may be emulsified at room temperature in concentrated surfactant and then added to the cooled product. Alternately, for example, the silicone conditioning agent can be mixed with anionic surfactant and fatty alcohol, such as cetyl and stearyl alcohols, at elevated temperature, to form a premix containing dispersed silicone. The premix can then be added to and mixed with the remaining materials of the personal cleansing composition, pumped through a high shear mill, and cooled. 
     The personal cleansing compositions illustrated in Example XXII (JJJ to QQQ) illustrate specific embodiments of the personal cleansing compositions of the present invention, but are not intended to be limiting thereof. Other modifications can be undertaken by the skilled artisan without departing from the spirit and scope of this invention. These exemplified embodiments of the personal cleansing compositions of the present invention provide cleansing of hair and/or skin and improved conditioning. 
     All exemplified compositions can be prepared by conventional formulation and mixing techniques. Component amounts are listed as weight percents and exclude minor materials such as diluents, filler, and so forth. The listed formulations, therefore, comprise the listed components and any minor materials associated with such components.

         Prepare enzyme solution by making a 1–2 mg/ml solution (to give O.D. at 405 nm of 1.2–1.7 with a target of 1.5) of purified acid phosphatase (0.5–1.0 units of activity/mg at room temperature) in HPLC water and keep on ice. Make fresh prior to use.   Prepare citrate buffer at pH4.5 by combining 0.82 g citric acid, 2.25 g sodium citrate, and Q.S. to 100 ml with HPLC water.   Prepare substrate/buffer solution: 3.0 mM p-nitrophenylphosphatase (F.W.263) in 10 mM citrate buffer@pH 4.5 (add 8 mg PNPP in 10 ml citrate buffer.   Prepare development solution: 0.5N NaOH.   Make 7 gpg water: Add 0.6 ml of hardness concentrate to 1000 ml of HPLC water       

     Partitioning Followed by Extraction of Surfactants into Stratum Corneum
         Place the surfactant solution (300 g) at the desired water hardness in a 115F waterbath to get to temperature.   Cut and weigh the predried porcine stratum corneum to get approximately the same size by weight sample from the same piece of pigskin for the treatments to be tested and compared.   Place the pigskins in the appropriate solutions, making sure the pigskins stay at the bottom of beaker to insure all surface is exposed to solution, and let soak for 30 minutes at the 115 F temperature.   After the soak, the pigskin is rinsed (or placed) in fresh room temperature 0 gpg water for 30 seconds.   After the rinse the pigskin is placed in a clean 15 ml vial and HQW (12–14 ml) is added to the vial and aluminum foil is placed on the top of vial before lid is screwed on.   The vial is placed in the 115 F waterbath for 2 hours and during the 2 hours inverted every ½ hr.   After the extraction for 2 hrs the pigskin is removed and discarded and the extract is evaporated to dryness using dry N2(overnight drying).   Reconstitute the dried extract with 0.4 ml HQW and place back into waterbath set at 50–55 C to insure surfactant goes in solution—the solution should be clear.       

     Addition of Surfactants to Microtiter Wells
         Place empty microtiter plate on pre-heated plate warming block (115F). Place thermometer in plate and wait for temperature to reach @ 113 F.   Add 50 ul of the heated extracted surfactant solutions (400 ul) to designated wells. Add 50 ul of 115 F water (hardness in which soak was conducted) to control wells and the blanks. Generally, blanks are run as the first well in each row. (see Appendix II for template setup)   Add 25 ul of the enzyme solution to each well except blanks (the control will have enzyme, but no surfactant, and will show the highest enzyme activity) as quickly as possible (&lt;30 sec.). Add 25 ul of the 115 F water (hardness in which soak was conducted) to the blanks. Once enzyme added to first well set timer for five minutes.   Move microtiter plate to plate shaker. Shake for 30 seconds.   Return microtiter plate to plate warming block for the duration of the five minutes. After the five minutes remove from heating block.   Add 75 ul of the substrate/buffer solution to each well using the multi-channel pipette. This step activates the enzyme to liberate product, so the solution must be added as quickly and as accurately as possible (&lt;30 sec.). Activate wells of a single row first before adding solution to wells of the next row.   After 3 minutes, quickly add 100 ul of 0.5N NaOH to each well using the multi-channel pipette. This step stops the reaction and develops the color for the spectrophotometric measurement at 405 nm using the plate reader, so this solution must also be added as quickly and as accurately as possible (&lt;30 sec.). The color will be stable for up to 30 minutes if the plate is covered.   Obtain absorbance results using plate reader set at 405 nm.       

     Background Correction
         Some surfactants may interfere at 405 nm and background correction is required for these materials. The correction is made by simply redoing the above 8 steps with the exception of adding the enzyme solution. This is replaced with 25 ul of water. Read wells at 405 nm and subtract background absorbance values from absorbances (average) derived from corresponding reacted wells. A background subtraction should be performed for every surfactant and product tested.       

     Calculation
         Subtract blank absorbance value from control absorbance value to obtain the absorbance of the control wells (maximum enzyme introduced in the experiment). Subtract surfactant absorbance backgrounds from appropriate surfactant—acid phosphatase absorbances to obtain absorbance of surfactant wells.   Derive Ratio of Inhibition (or % enzyme deactivation) for each concentration as follows:
 
[1−(absorbance of surfactant/absorbance of control)]*100
       

     Reporting
         Report the % enzyme deactivation of the different formulae tested and compare to a control product. An increase in % deactivation corresponds to greater product harshness outside the standard deviation of test method (+/−4%).
