Conditioning shampoo compositions

A hair conditioning shampoo composition is disclosed that contains (a) a surfactant component that can contain anionic surfactants and/or amphoteric surfactants (optionally including zwitterionic and nonionic surfactants), (b) a dispersed, insoluble, nonionic silicone hair conditioning agent, (c) a water soluble, organic, ampholytic polymer hair conditioning agent; and (d) an aqueous carrier. The conditioning shampoo composition optionally contains an organic, water insoluble, liquid.

FIELD OF THE INVENTION
 The present invention relates to shampoo compositions containing surfactant
 and conditioning ingredients. The present invention also relates to
 methods for treating hair.
 BACKGROUND OF THE INVENTION
 Clean human hair quickly returns to its "dirty" condition due to contact
 with the environment and due to the buildup of the sebum-secreted by the
 head. Within a short time (one day to a few days) hair begins to look and
 feel "dirty". In modern cultures, this look and feel is considered
 unacceptable requiring the wearer to shampoo their hair frequently. In
 some countries, the daily shampooing of hair is considered a normal
 requirement for proper hygiene, whether or not the hair has actually
 become "dirty".
 Shampooing cleans the hair by the removal of environmental contaminants
 along with the sebum. However, shampooing removes the natural oils and
 other moisturizing materials. If the hair is of significant length, the
 hair can be tangled and becomes unmanageable. Once dry, the hair has lost
 its shine and luster and can be dry and frizzy. Hair can also maintain a
 static charge when dry that results in "fly-away hair".
 As this problem has surfaced in the modern era, solutions have been
 developed to correct or to minimize the problem from frequent shampooing.
 The first acceptable solutions entailed the post-shampoo application of
 hair conditioners and hair rinses, generally while the hair is still wet
 immediately after shampooing. These conditioners and rinses were left on
 the hair for a period of time to allow sufficient treatment and then
 removed by rinsing with water. These solutions have, as late, been deemed
 inconvenient and time consuming. The solution to this problem has been the
 incorporation of conditioners into the shampoo itself, thus the advent of
 "conditioning shampoo".
 Shampoos that contain conditioners or conditioning agents have not been
 completely satisfactory for various reasons. Hair is composed of keratin,
 a sulfur-containing fibrous protein. The isoelectric point of keratin, and
 more specifically of hair, is generally in the pH range of 3.24.0.
 Therefore, at the pH of a typical shampoo (about 5.5-6.5), hair carries a
 net negative charge. Consequently, cationic polymers due to their positive
 charge have long been used as conditioners in shampoo formulations, or as
 a separate treatment, in order to improve the wet and dry combability of
 the hair. The substantivity of the cationic polymers for negatively
 charged hair along with film formation facilitates detangling during wet
 hair combing and a reduction in static flyaway during dry hair combing.
 Cationic polymers generally also impart softness and suppleness to hair.
 When cationic polymers are added to shampoos containing good cleaning
 anionic surfactants, formation of highly surface active association
 complexes generally takes place, which imparts improved foam stability to
 the shampoo but provides poor conditioning. Maximum surface activity and
 foam stability, or lather, are achieved at near stoichiometric ratios of
 anionic surfactant: cationic polymer, where the complex is least water
 soluble. However, cationic conditioners exhibit some incompatibility at
 these ratios. Compatibility gives a commercially more desirable clear
 formulation, while incompatibility leads to a haze or precipitation, which
 is aesthetically less desirable in some formulations. Additionally when
 cationic surfactants are added as an ingredient in the shampoo, they do
 not provide optimal overall conditioning to the hair in the area of
 softness and tend to build up on the hair resulting in an unclean feel.
 Nonionic silicones have also been disclosed in patents as a shampoo
 additive to increase the softness of hair. These patents include U.S. Pat.
 Nos. 2,826,551, 3,964,500, 4,364,837, and U.K. Patent No. 849,433. Shampoo
 compositions that contain insoluble silicone conditioners are disclosed in
 U.S. Pat. Nos. 4,741,855 and 4,788,066. Shampoo compositions containing
 anionic surfactants dispersed in soluble silicone (along with a cationic
 polymer with a cationic charge density of 3 meq/k or less and an oily
 liquid conditioning agent) are disclosed in WO93/08787 and in U.S. Pat.
 No. 5,573,709.
 Other publications disclosing the use of silicone conditioning agents
 include Japanese Patent Application No. 5672095, Laid Open Jun. 16, 1981,
 published EPO Application 413 416 and 413 417, both published Feb. 20,
 1991.
 Oily components have been added to shampoo formulations to improve the
 luster and shine of hair as disclosed in Japanese Patent Application
 Abstracts 53[1978]-35902, (54129135) and 62[1987]-327266 (168612).
 In spite of these attempts to provide optimal combinations of cleaning
 ability and hair conditioning, it remains desirable to provide further
 improved hair conditioning shampoo compositions. For instance, it remains
 desirable to improve overall conditioning, and especially shine and
 luster, wet and dry combing, and dry hair feel, of hair treated with
 shampoo containing silicone and cationic material. For shampoos containing
 oily materials in combination with cationic materials, it remains
 desirable to improve overall conditioning:, especially wet combing and
 detangling, dry combing, and dry hair feel. However merely increasing the
 level of one or both conditioning ingredients can result in adverse
 effects such as greasy hair feel and loss of fullness. It is desirable to
 improve conditioning without suffering from these drawbacks.
 It is desirable to provide shampoo compositions and methods for cleaning
 and conditioning hair which can provide excellent cleaning performance and
 improved levels of conditioning while minimizing any adverse side effects
 associated with build-up due to the use of excess conditioning agent.
 SUMMARY OF THE INVENTION
 The hair conditioning shampoo composition of the present invention
 comprises:
 (a) about 5% to about 50%, by weight, of a surfactant component selected
 from the group consisting of anionic surfactants and amphoteric
 surfactants;
 (b) about 0.05% to about 10%, by weight, of a dispersed, insoluble,
 nonvolatile, nonionic silicone hair conditioning agent;
 (c) about 0.05% to about 10%, by weight, of a water soluble, organic,
 ampholytic polymer hair conditioning agent; and
 (d) an aqueous carrier.
 The method for treating hair according to the present invention comprises
 contacting the hair with the composition above.
 DETAILED DESCRIPTION OF THE INVENTION
 This invention provides anionic and/or amphoteric detersive surfactant
 containing liquid shampoo compositions that can provide both excellent
 cleaning performance and hair conditioning benefits to a wide variety of
 hair types. This is attained by forming a hair conditioning system shampoo
 composition that includes the surfactant, an aqueous carrier, a dispersed
 insoluble, nonionic, silicone hair conditioning agent, a water soluble,
 organic ampholytic polymer hair conditioning agent, and optionally, an
 organic, water insoluble oily liquid.
 It has now been unexpectedly found that improved overall conditioning can
 be found by combining surfactant in a shampoo with dispersed, insoluble,
 and nonionic silicone, a soluble organic ampholytic polymer hair
 conditioning agent. Conditioning is also improved with the addition of a
 preferred optional organic water insoluble liquid component.
 These compositions can provide improved conditioning while reducing the
 level of undesirable side effects that can result from increasing the
 level of conditioning agent in prior known conditioning systems. As
 discussed previously, a conditioning agent system containing too much of a
 particular component can cause buildup. Too much silicone can result in
 silicone build up on the hair over repeated usage and a loss of fullness
 of the hair. Too much organic liquid (oil) results in an oily feel and a
 loss of fullness of the hair. Too much conditioning agent results in a
 slick, oily feel of the hair. Now it has been found that combining these
 specific types of ingredients--surfactant, insoluble nonionic silicones,
 ampholytic polymers, and the optional oily organic liquids--can provide
 improved overall conditioning while minimizing the adverse effects of
 conditioning agent build-up that otherwise can be incurred upon increasing
 the levels of individual components in prior known conditioning systems.
 Furthermore, the use of ampholytic polymer in the compositions hereof can
 improve performance relative to similar systems with cationic polymers in
 combination with silicone and oily liquid conditioning agents.
 The present invention provides hair conditioning shampoo compositions
 comprising: about 5% to about 50%, by weight, of component (a), about
 0.05%. to about 10%, by weight, of component (b); about 0.05% to about
 10%, by weight, of component (c); and an aqueous carrier (d). The hair
 conditioning shampoo compositions preferably contain about 0.05% to about
 5%, by weight, of an organic, water insoluble, liquid that is more
 preferably selected from the group consisting of hydrocarbon oils, fatty
 esters having 10 or more carbon atoms, and mixtures thereof. The hair
 conditioning shampoo compositions can also contain from 0% to about 10%,
 by weight, of a zwitterionic surfactant component.
 A specific preferred composition according to the present invention
 comprises; (a) containing about 15 weight % anionic surfactant and about 1
 to 2 weight % nonionic surfactant, (b) containing about 0.5 to 1.5%
 silicone, and (c) containing about 0.2 to 0.4 weight percent of said
 ampholytic polymer hair conditioning agent.
 The optional organic water insoluble liquid is an oily liquid conditioning
 agent and is preferably intermixed in, and is distributed throughout, the
 composition. The organic water insoluble liquid is generally selected from
 the group consisting of hydrocarbon oils and fatty esters. As used herein,
 "fatty ester" means esters having 10 or more carbon atoms.
 The insoluble silicone conditioning agent is dispersed throughout the
 composition in the form of droplets or particles. Preferably, a suitable
 suspending agent is utilized to facilitate stability of the dispersed
 silicone.
 As used herein, the terms "soluble" and "insoluble" used in reference to
 particular ingredients of the shampoo compositions refer to solubility or
 insolubility, respectively, of that ingredient in the shampoo composition,
 unless otherwise specifically indicated. For example the terms "water
 soluble" and "water insoluble", as used herein, refer to solubility of the
 particular ingredient in water, as opposed to solubility in the shampoo
 composition.
 All percentages are calculated by weight of the total composition unless
 otherwise specifically indicated. All ratios are weight ratios unless
 otherwise specifically indicated.
 Ampholytic Polymer Hair Conditioning Agent
 The shampoo composition of the present invention comprises a water soluble,
 ampholytic organic polymer hair conditioning agent as an essential
 element. The polymeric ampholytic hair conditioning agent hereof will
 generally be present at levels of from about 0.05% to about 10% by weight
 preferably about 0.05% to about 5%, more preferably from about 0.1% to
 about 4%, with about 0.2% to about 3%, by weight, of the shampoo
 composition being most preferred. By "water soluble" ampholytic organic
 polymer, what is meant is a polymer which is sufficiently soluble in water
 to form a substantially clear solution to the naked eye at a concentration
 of 0.1% in water (distilled or equivalent) at 25.degree. C. Preferably,
 the polymer will be sufficiently soluble to form a substantially clear
 solution at 0.5% concentration, more preferably at 1.0% concentration.
 The ampholytic organic polymers useful in the hair conditioning agent
 hereof are organic polymers that can provide conditioning benefits to hair
 and that are soluble in the shampoo composition. Any ampholytic polymers
 which can provide these benefits can be used regardless of the cationic
 charge density of the polymer.
 The water soluble, organic, hair conditioning agent of the ampholytic
 polymer hair conditioning shampoo composition according the present
 invention is preferably comprised of:
 (A) about 1 to about 99 mol % of at least one monomer selected from the
 group consisting of alkyl acrylamidopropyl-dimethyl ammonium halides,
 alkyl methacrylamidopropyldimethyl ammonium halides, alkyl
 acryloyloxyethyl dimethyl ammonium halides, alkyl methacryloyloxyethyl
 dimethyl ammonium halides, and dialkyl diallyl ammonium halides;
 (B) about 1 to about 99 mol % of at least one monomer selected from the
 group consisting of acrylic acid (AA), methacrylic acid (MAA),
 2-acrylamido-2-methylpropane sulfonic acid (AMPSA)
 2-methacrylamido-2-methylpropane sulfonic acid (MAMPSA),
 n-methacrylamidopropyl,n,n-dimethyl,amino acetic acid,
 n-acrylamidopropyl,n,n-dimethyl,amino acetic acid,
 n-methacryloyloxyethyl,n,n-dimethyl,amino acetic acid, and
 n-acryloyloxyethyl,n,n-dimethyl,amino acetic acid; and
 (C) about 0 to about 80 mol % of at least one monomer selected from the
 group consisting of C.sub.1 -C.sub.22 straight or branched chain alkyl
 acrylate or methacrylate, a C.sub.1 -C.sub.22 straight or branched chain
 n-alkyl acrylamide or methacrylamide, acrylamide methylacrylamide,
 n-vinylpyrrolidone, vinyl acetate or ethoxylated and propoxylated acrylate
 or methacrylate; with a weight average molecular weight of, as determined
 by viscometry, of at least about 50,000.
 The water soluble, organic, ampholytic polymer hair conditioning agents of
 the present invention are organic polymers which more preferably comprise:
 (A) acrylamidopropyltrimethyl ammonium chloride (APTAC),
 methacrylamidopropyltrimethyl ammonium chloride (MAPTAC), acryloyloxyethyl
 trimethyl ammonium chloride (AETAC), methacryloyloxyethyl methyl sulfate
 (METAMS), methacryloyloxyethyl trimethyl ammonium chloride (METAC), or
 dimethyl diallyl ammonium chloride (DMDAAC);
 (B) AA, MAA, AMPSA, and MAMPSA; and
 (C) optionally, a C.sub.1 -C.sub.22 straight or branched alkyl acrylate or
 methacrylate, such as methyl, ethyl, butyl, octyl, lauryl, and stearyl
 acrylate esters, and methacrylate esters; acrylamide;
 methacrylamide; a C.sub.1 -C.sub.22 straight or branched n-alkyl acrylamide
 or methacrylamide such as n-methyl, n-ethyl, n-butyl, n-octyl, t-octyl,
 n-lauryl, and n-stearyl acrylamides and methacrylamides.
 The shampoo composition has a pH preferably between about pH 3 and about pH
 9, more preferably from about pH 4 to about pH 8.
 Preferably, the mol ratio of (A):(B) in said ampholytic polymer ranges from
 about 20:80 to about 95:5, more preferably from about 25:75 to about
 75:25. Further, the weight average molecular weight of said polymer, as
 determined by viscometry, is preferably at least about 100,000, more
 preferably from about 100,000 to about 10,000,000, with a weight average
 molecular weight of about 200,000 to about 8,000,000 being most preferred.
 Alternatively, gel permeation chromatography (GPC) with light scattering
 detection can be used with approximately the same numbers.
 Optionally, but preferably, the instant polymers additionally contain, are
 further comprised of or are prepared using (C) up to about 80 mol percent,
 preferably at least about 0.1 mol percent, of a C.sub.1 -C.sub.22 straight
 or branched chain alkyl acrylate or methacrylate, preferably a C.sub.1
 -C.sub.4 alkyl acrylate and most preferably methyl acrylate, a C.sub.1
 -C.sub.22 straight or branched chain n-alkyl acrylamide or methacrylamide,
 preferably a C.sub.1 -C.sub.4 alkyl acrylamide and most preferably
 acrylamide, wherein the upper mol percent of (C) in the instant polymers
 is limited by solubility considerations.
 A more preferred molecular weight range for the instant polymers is from
 about 200,000 to about 8,000,000, as determined by viscosity or GPC. For
 example, reduced viscosity values can be used to approximate the weight
 average molecular weights of the instant polymers. Preferably, the mol
 ratio of (A):(B) ranges from 25:75 to about 75:25, and the preferred
 polymers contain at least about 0.1 up to about 20 mol % of the
 above-defined acrylates, methacrylates, acrylamides, methacrylamides,
 vinyl acetate, vinyl alcohol and/or n-vinyl pyrrolidone. More preferably,
 the instant polymers contain about 5 to about 15 mol % of the acrylate,
 methacrylate, acrylamide, methacrylamide, vinyl acetate, vinyl alcohol
 and/or n-vinyl pyrrolidone moiety. In the most preferred case, methyl
 acrylate and/or acrylamide.
 Specific preferred examples of the ampholytic polymer hair conditioning
 agent according to the present invention include (1) a polymer comprised
 of about 45 mol % MAPTAC, about 45 mol % acrylic acid, and about 10 mol %
 methylacrylate and (2) a polymer comprised of about 30 mol % DMDAAC, about
 35 mol % acrylic acid, and about 35 mol % acrylamide. These polymers are
 available from Calgon Corporation as MERQUAT 2001 and MERQUAT plus 3330,
 respectively.
 As discussed above, the ampholytic polymer hereof is water soluble. This
 does not mean, however. that it must be soluble in the shampoo
 composition. Preferably however, the ampholytic polymer is either soluble
 in the shampoo composition, or in a complex coacervate phase in the
 shampoo composition formed by the ampholytic polymer and other ionic
 materials. Complex coacervates of the ampholytic polymer can be formed
 with anionic surfactants, amphoteric surfactants, zwitterionic
 surfactants, cationic surfactants or with appropriately charged
 polyelectrolytes that can optionally be added to the compositions hereof.
 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
 has previously been studied. See, far example, J. Caelles, et al) "Anionic
 and Cationic Compounds in Mixed Systems", Cosmetics & 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.
 It is believed to be particularly advantageous for the ampholytic polymer
 to be present in the shampoo in a coacervate phase, or to form a
 coacervate phase upon application or rinsing of the shampoo to or from the
 hair. Complex coacervates are believed to more readily deposit on the
 hair. Thus, in general, it is preferred that the ampholytic polymer exist
 in the shampoo as a coacervate phase or form a coacervate phase upon
 dilution. If not already a coacervate in the shampoo, the ampholytic
 polymer will preferably exist in a complex coacervate form in the shampoo
 upon dilution with water to a water:shampoo composition weight 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 shampoo 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 phases
 dispersed in the composition.
 Exemplary complex coacervate shampoo compositions are shown in the
 examples.

 Silicone Hair Conditioning Agent
 An essential component of the present invention is a nonvolatile, nonionic
 silicone hair conditioning agent which is insoluble in the shampoo
 compositions hereof. The silicone hair conditioning agent is intermixed in
 the shampoo composition so as to be in the form of dispersed, insoluble
 particles, or droplets. The silicone hair conditioning agent comprises a
 nonvolatile, insoluble, silicone fluid and optionally comprises a silicone
 gum which is insoluble in the shampoo composition as a whole but is
 soluble in the, silicone fluid. The silicone hair conditioning agent can
 also comprise other ingredients, such as a silicone resin to enhance
 deposition efficiency.
 The silicone hair conditioning agent may comprise low levels of volatile
 silicone components; however, such volatile silicones will preferably
 exceed no more than about 0.5%, by weight, of the shampoo composition.
 Typically, if volatile silicones are present, it will be incidental to
 their use as a solvent or carrier far commercially available forms of
 other ingredients, such as silicone gums and resins The silicone hair
 conditioning agent for use herein will preferably have viscosity of from
 about 1,000 to about 2,000,000 centistokes at 25.degree. C., more
 preferably from about 10,000 to about 1,800,000, 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 Coming Corporate test
 method CTM0004, Jul. 20, 1970.
 The silicone hair conditioning agent will be used in the shampoo
 compositions hereof at levels of from about 0.5% to about 10% by weight of
 the composition, preferably from about 0.1% to about 10%, more preferably
 from about 0.5% to about 8%, most preferably from about 0.5% to about 5%.
 Suitable insoluble, nonvolatile silicone fluids include polyalkyl
 siloxanes, polyaryl siloxanes, polyalkylaryl siloxanes, polyether siloxane
 copolymers, and mixtures thereof. Other insoluble, nonvolatile silicones
 fluids having hair conditioning properties can also be used. The term
 "nonvolatile" as used herein shall mean that the silicone material
 exhibits very low or no significant vapor pressure at ambient conditions,
 as is understood by those in the art. The term "silicone fluid" shall mean
 flowable silicone materials having a viscosity of less than 1,000,000
 centistokes at 25.degree. C. Generally, the viscosity of the fluid will be
 between about 5 and 1,000,000 centistokes at 25.degree. C., preferably
 between about 10 and about 100,000.
 The nonvolatile polyalkylsiloxane fluids that may be used include, for
 example, polydimethyl siloxanes. These siloxanes are available, for
 example, from the General Electric Company in their Viscasil.RTM. and SF
 96 series, and from Dow Corning in their Dow Coming 200 series.
 The polyalkylaryl siloxane fluids that may be used, also include, for
 example, polymethylphenylsiloxanes. These siloxanes are available, for
 example, from the General Electric Company as SF 1075 methyl phenyl fluid
 or from Dow Coming as 556 Cosmetic Grade Fluid.
 The polyether siloxane copolymers that may be used include, for example, a
 polypropylene oxide modified polydimethylsiloxane (e.g., Dow Corning
 DC-1248) although ethylene oxide or mixtures of ethylene oxide and
 propylene oxide may also be used. The ethylene oxide and polypropylene
 oxide level must be sufficiently low to prevent solubility in water and

 Also incorporated herein by reference is ,Silicon Compounds distributed by
 Petrarch Systems, Inc., 1984. This reference provides an extensive (though
 not exclusive) listing of suitable silicone fluids.
 Another silicone material that can be especially useful in the silicone
 conditioning agents is insoluble silicone gum. The term "silicone gum", as
 used herein, means polyorganosiloxane materials having a viscosity at
 25.degree. C. of greater than or equal to 1,000,000 centistokes. Silicone
 gums are described by Petrarch and others including U.S. Pat. No.
 4,152,416, 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. 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, (polydimethyl siloxane) (methylvinylsiloxane)
 copolymer, poly(dimethyl siloxane) (diphenyl
 siloxane)(methylvinylsiloxane) copolymer and mixtures thereof.
 Preferably the silicone hair conditioning agent comprises a mixture of a
 polydimethylsiloxane gum, having a viscosity greater than about 1,000,000
 centistokes and polydimethyl siloxane fluid having a viscosity of from
 about 10 centistokes to about 100,000 centistokes, wherein the ratio of
 gum to fluid is from about 30:70 to about 70:30, preferably from about
 40:60 to about 60:40.
 Another optional ingredient that can be included in the silicone
 conditioning agent is silicone resin. Silicone resins 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-, trimethy-, 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 silicones 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.
 Background material on silicones including sections discussing silicone
 fluids , gums, and resins, as well as manufacture of silicones, can be
 found in Encyclopedia of Polymer science and Engineering, Volume 15,
 Second Edition, pp.294-308, John Wiley & Sons, Inc., 1989, incorporated
 herein by reference.
 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 "MDTQ" nomenclature. Under this system, the
 silicone is described according to presence of various siloxane monomer
 units which make up the silicone . Briefly, the symbol M denotes the
 monofunctional unit (CH.sub.3).sub.3 SiO.sub.0.5 ; D denotes the
 difunctional unit (CH.sub.3).sub.2 SiO; T denotes the trifunctional unit
 (CH.sub.3)SiO.sub.1.5 ; and Q denotes the quadri- or tetra-functional unit
 SiO.sub.2. Primes of the unit symbols, 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, phenyls,
 amines, hydroxyls, 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 MDTP 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.
 The weight ratio of the nonvolatile silicone fluid component to the
 silicone resin component, when used, is from about 4:1 to about 400:1,
 preferably this ratio is from about 9:1 to about 200:1, more preferably
 from about 19:1 to about 100:1, particularly when the silicone fluid
 component is a polydimethyl siloxane fluid or a mixture of
 polydimethylsiloxane fluid and polydimethylslloxane gum as described
 above.
 Examples of the more preferred silicones used as component (b) include,
 dimethicone, cyclomethicone, trimethyl silyl amodimethicone, phenyl
 trimethicone, trimethyl siloxy silicate, polyorganosiloxane,
 polyalkylsiloxane, polyarylsiloxane, polyalkylarylsiloxane, and
 polyestersiloxane copolymers.
 It has been found that for compositions containing silicone and a
 conditioning oily liquid (as described below), ampholytic polymer
 conditioning agents having sufficiently high cationic charge density
 within the above range can provide enhanced conditioning performance and
 coacervate formation.

 Aqueous Carrier
 The shampoo compositions of the present invention are typically liquids
 which, preferably, are pourable at room temperature. The compositions
 hereof will comprise an aqueous carrier, i.e., water, which will generally
 be present at a level of about 20% to about 95% by weight of the
 composition, preferably from about 60% to about 85% for pourable, liquid
 formulations. The compositions of the present invention can also be in
 other forms, such as gels, mouse, etc. In such cases, appropriate.
 components known in the art such as gelling agents (e.g., hydroxyethyl
 cellulose), etc. can be included in the compositions. Gels will typically
 contain from about 20% to about 90% water. Mousses will be a low viscosity
 composition and will be packaged as a sprayable liquid according to
 techniques well known in the art, typically in an aerosol canister
 including a propellant or a means for generating an aerosol spray.
 Since the silicone conditioning agent used in the present compositions is
 an insoluble silicone dispersed in the compositions, it is preferred to
 utilize a suspending agent for the silicone. Suitable suspending agents
 are long chain acyl derivatives, long chain amine oxides, and mixtures
 thereof, wherein such suspending agents are present in the shampoo
 compositions in crystalline form. A variety of such suspending agents are
 described in U.S. Pat. No. 4,741,855, Grote et al., issued May 3, 1988.
 Especially preferred is ethylene glycol distearate.
 Also included among the long chain acyl derivatives useful as suspending
 agents are the N,N-di(hydrogenated) C.sub.8 -C.sub.22 (preferably C.sub.12
 -C.sub.22, more preferably C.sub.16 -C.sub.18) amido benzoic acid, or
 soluble salt (e.g., K, Na salts) thereof particularly
 N,N-di(hydrogenated)tallow amido benzoic acid which is commercially
 marketed by Stepan Company (Northfield, Ill., USA).
 Another useful suspending agent for the silicone conditioning agents of the
 present compositions is xanthan gum as described in U.S. Pat. No.
 4,788,006, Bolich et al., issued Jun. 5, 1984. The combination of long
 chain acyl derivatives and xanthan gum as a suspending system for silicone
 is described in U.S. Pat. No. 4,704,272, Oh et al., issued Nov. 3, 1987,
 and may also be used in the present compositions.
 Generally, the shampoo compositions will comprise from about 0.1% to about
 5.0%, preferably from about 0.5% to about 3.0%, of the suspending agent to
 suspend the silicone conditioning agent.
 Optional Components
 The present compositions may also comprise a variety non-essential,
 optional shampoo components suitable for rendering such compositions more
 cosmetically or aesthetically acceptable or to provide them with
 additional usage benefits. A variety of such to those skilled in the art,
 and these ingredients are well-known include without limiting the
 invention thereto: pearlescent aids, such as coated mica, ethylene glycol
 distearate; opacifiers, such as Tin,; preservatives, such as
 1,2-dibromo-2,4-dicyano butane (MERGUARD, Calgon Corporation, Pittsburgh,
 Pa., USA), benzyl alcohol, 1,3-bis(hydroxymethyl)-5,
 5-dimethyl-2,3-imidazolidinedione (e.g., GLYDANT, Glyco Inc., Greenwich,
 Conn., USA), methylchloroisothiazolinone (e.g., Kathon, Rohm & Haas Co.,
 Philadelphia, Pa., USA), methyl paraben, propyl paraben, and
 imidazolidinyl urea; fatty alcohols, such as cetearyl alcohol, cetyl
 alcohol, and stearyl alcohol; sodium chloride; amnonium chloride; sodium
 sulfate; ethyl alcohol; pH adjusting aids, such as citric acid, sodium
 citrate, succinic acid, phosphoric acid, monosodium phosphate, disodium
 phosphate, sodium hydroxide, and sodium carbonate; coloring agents or
 dyes; perfumes; and sequestering agents, such as disodium ethylenediamine
 tetra-acetate (EDTA).
 Another optional ingredient that can be advantageously used is an
 anti-static agent. The anti-static agent should not unduly interfere with
 the in-use performance and end-benefits of the shampoo; particularly, the
 anti-static agent should not interfere with the anionic detersive
 surfactant. Suitable anti-static agents include, for example, tricetyl
 methyl amnonium chloride.
 Typically, from about 0.1% to about 5%; of such anti-static agent is
 incorporated into the shampoo compositions.
 Though the silicone suspending agent component may act to thicken the
 present compositions to some degree, the present compositions may also
 optionally contain other thickeners and viscosity modifiers such as an
 ethanolamide of a long chain fatty acid, such as polyethylene (3) glycol
 lauramide and coconut monoethanolamide (cocamide MEA) and ammonium xylene
 sulfonate.
 These optional components generally are used individually in the
 compositions of the present invention at a level of from about 0.01% to
 about 10%, preferably from about 0.05% to about 5.0% of the shampoo
 composition.
 Method of Manufacture
 The compositions of the present invention, in general, can be made by
 mixing the materials together at elevated temperature, e.g., about
 72.degree. C. The silicones resin, if any, and silicone fluid component
 are first mixed together before being mixed with the other ingredients.
 The other ingredients are added and the complete mixture is mixed
 thoroughly at the elevated temperature and is then pumped through a high
 shear mill and then through a heat exchanger to cool it to ambient
 temperature. A portion of the liquid components or soluble components
 (including, for example, ampholytic polymer conditioning agent) can be
 added to the composition after cooling the mix of surfactants and solids.
 Method of Use
 The shampoo compositions of the present invention are utilized
 conventionally, i.e., the hair is shampooed by applying an effective
 amount of the shampoo composition to the scalp, and then rinsing it out
 with water. Application of the shampoo to the scalp in general,
 encompasses messaging or working the shampoo in the hair such that all or
 most of the hair on the scalp is contacted. The term an "effective amount"
 as used herein, is an amount which is effective in cleaning and
 conditioning the hair. Generally, from about 1 g to about 20 g of the
 composition is applied for cleaning and conditioning the hair. preferably,
 the shampoo is applied to hair in a wet or damp state.
 The compositions hereof can also be useful for cleaning and conditioning
 the skin. For such applications, the composition would be applied to the
 skin in a conventional manner, such as by rubbing or massaging the skin
 with the composition, optionally in the presence of water, and then
 rinsing it away with water.
