Description: HAIR CONDITIONING COMPOSITIONS TECHNICAL FIELD The present invention relates to hair conditioning compositions free of quaternary ammonium compounds. More specifically, the present invention relates to a hair conditioning composition comprising an amidoamine, an acid, a high melting point compound, an oily compound, and water. BACKGROUND Scalp and hair become soiled due to their contact with the surrounding environment and from sebum secreted from the hair follicles. The build-up of sebum and environmental soiling can cause the hair to have a dirty or greasy feel, and an unattractive appearance. In order to ameliorate these effects, it is necessary to shampoo the hair with regularity. Shampooing the hair removes excess sebum and other environmental soiling but has disadvantages in that the hair can be left in a wet, tangled, and relatively unmanageable state. Shampooing can also result in the hair becoming dry due to the removal of natural oils or other hair moisturizing materials. After shampooing, the hair can also suffer from a perceived loss of "softness." Frequent shampooing also contributes to the phenomena of "split ends," particularly for long hair. Split ends refers to a condition wherein the ends of the hair are split into two or more shafts, resulting in a frizzy appearance. A variety of approaches have been developed to condition the hair. These range from post-shampooing hair rinses, to leave-on hair conditioners, to the inclusion of hair conditioning components in shampoos. Although many consumers prefer the ease and convenience of a shampoo which includes conditioners, a substantial proportion of consumers prefer the more conventional conditioner formulations which are applied to the hair as a separate step from shampooing, usually subsequent to shampooing. These hair conditioners typically are formulated as a thickened product, such as a gel or cream, for ease of dispensing and application to the hair. Hair conditioning compositions have conventionally been based on the combination of a cationic surfactant, which is generally a quaternary ammonium compound such as ditallowdimethylammoniumchlo de, in combination with various conditioning agents such as amidoamines, fatty alcohols, or oily compounds. These combinations generally result in a gel-network structure which provides the compositions with a thick, creamy texture. However, quaternary ammonium compounds may cause harshness and irritation to scalp, hair and/or skin. Further, some of the quaternary ammonium compounds such as ditallowdimethylammonium chloride are not biodegradable, and consequently are not preferred in view of environmental requirements. In addition, consumers tend to prefer conditioners which provide certain feel to the wet hair such as ease of spreading and ease of rinsing, as well as to the dry hair such as hair smoothness and softness, lustery appearance, and easy combing. Use of amidoamines in conditioning compositions are known in the art, such as in Japanese Patent Laid-open No. H5-271035, H5-271036, and H7- 2629. Use of oily compounds in conditioning compositions such as low melting point fatty alcohols are also known in the art. Based on the foregoing, there is a need for a hair conditioning composition which is substantially free of quaternary ammonium compounds, while continuing to provide preferable conditioning benefits. None of the existing art provides all of the advantages and benefits of the present invention. SUMMARY The present invention is directed to a hair conditioning composition comprising by weight: (a) from about 0.4% to about 5.0% of an amidoamine; (b) from about 0.05% to about 2.0% of an acid; (c) from about 1% to about 15% of a high melting point compound having a melting point of at least about 25°C selected from the group consisting of fatty alcohols, fatty acids, fatty alcohol derivatives, fatty acid derivatives, hydrocarbons, steroids, and mixtures thereof; (d) from about 0.02% to about 2% of an oily compound having a melting point of not more than about 25°C selected from the group consisting of a first oily compound, a second oily compound, and mixtures thereof; and (e) water; wherein the molar ratio of the amidoamine to acid is from about 1 : 0.3 to about 1 : 1 , wherein the composition is substantially free of quaternary ammonium compounds. The present invention is further directed to a suitable process for providing the hair conditioning composition. These and other features, aspects, and advantages of the present invention will become evident to those skilled in the art from a reading of the present disclosure.

Suitable conditioning agents are cationic polymers, silicones, proteins, and mixtures thereof. Cationic Polymers Cationic polymers useful herein are those which are more or less water soluble. As used herein, the term "polymer" shall include materials whether made by polymerization of one type of monomer or made by two (i.e., copolymers) or more types of monomers. By "water soluble" cationic 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°C. The preferred polymer will be sufficiently soluble to form a substantially clear solution at 0.5% concentration, more preferably at 1.0% concentration. The cationic polymers hereof will generally have a weight average molecular weight which is at least about 5,000, typically at least about 10,000, and is less than about 10 million. Preferably, the molecular weight is from about 100,000 to about 2 million. The cationic polymers will generally have cationic nitrogen-containing moieties such as quaternary ammonium or cationic amino moieties, and mixtures thereof. The cationic charge density is preferably at least about 0.1 meq/gram, more preferably at least about 1.5 meq/gram, even more preferably at least about 1.1 meq/gram, still more preferably at least about 1.2 meq/gram. Cationic charge density of the cationic polymer can be determined according to the Kjeldahl Method. Those skilled in the art will recognize that the charge density of amino-containing polymers may vary depending upon pH and the isoelectric point of the amino groups. The charge density should be within the above limits at the pH of intended use. Any anionic counterions can be utilized for the cationic polymers so long as the water solubility criteria is met. Suitable counterions include halides (e.g., CI, Br, I, or F, preferably CI, Br, or I), sulfate, and methylsulfate. Others can also be used, as this list is not exclusive. The cationic nitrogen-containing moiety will be present generally as a substituent, on a fraction of the total monomer units of the cationic hair conditioning polymers. Thus, the cationic polymer can comprise copolymers, terpolymers, etc. of quaternary ammonium or cationic amine-substituted monomer units and other non-cationic units referred to herein as spacer monomer units. Such polymers are known in the art, and a variety can be found 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). Suitable cationic polymers include, for example, copolymers of vinyl monomers having cationic amine or quaternary ammonium functionalities with water soluble spacer monomers such as acrylamide, methacrylamide, alkyl and dialkyl acrylamides, alkyl and dialkyl methacrylamides, alkyl acrylate, alkyl methacrylate, vinyl caprolactone, and vinyl pyrrolidone. The alkyl and dialkyl substituted monomers preferably have C<| - C7 alkyl groups, more preferably C-| - C3 alkyl groups. Other suitable spacer monomers include vinyl esters, vinyl alcohol (made by hydrolysis of polyvinyl acetate), 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 composition. In general, secondary and tertiary amines, especially tertiary amines, are preferred. Amine-substituted vinyl monomers can be polymerized in the amine form, and then optionally can be converted to ammonium by a quatemization reaction. Amines can also be similarly quaternized subsequent to formation of the polymer. For example, tertiary amine functionalities can be quaternized by reaction with a salt of the formula R'X wherein R' is a short chain alkyl, preferably a C-j - C7 alkyl, more preferably a C^ - C3 alkyl, and X is an anion which forms a water soluble salt with the quaternized ammonium. Suitable cationic amino and quaternary ammonium monomers include, for example, vinyl compounds substituted with dialkylaminoalkyl acrylate, dialkylaminoalkyl methacrylate, monoalkylaminoalkyl acrylate, monoalkylaminoalkyl methacrylate, trialkyl methacryloxyalkyl ammonium salt, trialkyl acryioxyalkyl ammonium salt, diallyl quaternary ammonium salts, and vinyl quaternary ammonium monomers having cyclic cationic nitrogen-containing rings such as pyridinium, imidazolium, and quaternized pyrrolidone, e.g., alkyl vinyl imidazolium, alkyl vinyl pyridinium, alkyl vinyl pyrrolidone salts. The alkyl portions of these monomers are preferably lower alkyls such as the C-j - C3 alkyls, more preferably C-| and C 2 alkyls. Suitable amine-substituted vinyl monomers for use herein include dialkylaminoalkyl acrylate, dialkylaminoalkyl methacrylate, dialkylaminoalkyl acrylamide, and dialkylaminoalkyl methacrylamide, wherein the alkyl groups are preferably C^ - C7 hydrocarbyls, more preferably C-j - C3, alkyls.

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 index 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 nonvolatile dispersed 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 nonvolatile dispersed silicones include amino substituted materials. Suitable alkylamino substituted silicones include those represented by the following structure (II) CH3 R I I HO - [Si- O ] x - [Si - 0] y - H (II) I I CH3 (CH 2 )3 I NH I (CH2)2 I NH2 wherein R is CH3 or OH, 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 amino substituted silicones include those represented by the formula (III) (R 1 )a G 3-a- si -(-° siG 2)n-(-OSiG b (R 1 )2. b)m -0-SiG 3 . a (R 1 ) a (III) in which G is chosen from the group consisting of hydrogen, phenyl, OH, C-i-Ce 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 CqH 2 qL in which q is an integer from 2 to 8 and L is chosen from the groups -N(R2)CH 2 -CH 2 -N(R2) 2 -N(R2) 2 -N(R2) 3 A- -N(R2)CH 2 -CH 2 -NR2H 2 A " in which R2 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 amino substituted silicones corresponding to formula (III) is the polymer known as "trimethylsilylamodimethicone", of formula (IV): CH3 OH I I (CH3) 3Si- 0 [Si- 0]n- [Si- 0] m - Si(CH3)3 (IV) I I CH3 (CH 2 )3 I NH I (CH2)2 I H2 In this formula n and m are selected depending on the exact molecular weight of the compound desired. Other amino substituted silicones which can be used are represented by the formula (V): R4CH2-CH0H-CH2-N + (R3) 3Q " R3 (CH3)3Si- 0 - [Si- 0] r - [Si- 0] s - Si(CH3)3 (V) I I R3 R3 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-| - C-jβ alkylene radical or a C<| - C « |8. and more preferably C-| - Cβ, alkyleneoxy radical; Q is a halide, 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." References disclosing suitable nonvolatile dispersed silicones include U.S. Patent No. 2,826,551, to Geen; U.S. Patent No. 3,964,500, to Drakoff, issued June 22, 1976; U.S. Patent 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 nonvolatile dispersed silicones 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, and others including U.S. Patent 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, polydimethylsiloxane diphenylsiloxane methylvinylsiloxane) copolymer and mixtures thereof. Also useful are silicone resins, which are highly crosslinked polymeric siloxane systems. The crossiinking is introduced through the incorporation of tri- functional and tetra-functional silanes with mono-functional or di-functional, or both, silanes during manufacture of the silicone resin. As is well understood in the art, the degree of crossiinking 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 crossiinking, 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 crossiinking 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 methylvinylchlorosilanes, 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 bound 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 & 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 mono-functional unit (CH3)3SiO) 5; D denotes the difunctional unit (CH3) 2 SiO; T denotes the trifunctional unit (CH3)SiO-| 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, hydroxyi, 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 crossiinking. As discussed before, however, the overall level of crossiinking 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. Proteins Proteins useful herein include proteins derived from a natural source, and protein derivatives. Nonlimiting examples of proteins include hydrolysed collagen, hydrolysed keratin, and proteins. Commercially available proteins useful herein include: materials having tradenames CROTEIN series available from Croda, and PROMOIS series available from Seiwa Kasei. ADDITIONAL COMPONENTS A wide variety of other additional components can be formulated into the present composition. These additional components are selected by the artisan according to the desired characteristics of the final product. Additional components include nonionic surfactants, amphoteric surfactants, zwitterionic surfactants; aqueous solvents such as C1.5 alkyl monohydric alcohols and polyvinyl alcohol; oily solvents such as volatile and non-volatile silicone fluids of low molecular weight; thickening agents and suspending agents such as xanthan gum, guar gum, hydroxyethylcellulose, methylcellulose, starch and starch derivatives; viscosity modifiers such as methanolamides of long chain fatty acids such as cocomonoethanolamide; peariescent aids such as ethylene glycol distearate; preservatives such as benzyl alcohol, methyl paraben, propyl paraben, imidazolidinyl urea, methylchloroisothiazoline, and methylisothiazoline; pH adjusting agents, such as sodium citrate, phosphoric acid, sodium hydroxide, and sodium carbonate; salts, in general, such as potassium acetate and sodium chloride; coloring agents, such as any of the FD&C or D&C dyes; hair oxidizing (bleaching) agents, such as hydrogen peroxide, perborate and persulfate salts; hair reducing agents such as the thioglycolates; perfumes; sequestering agents such as ethylenediamine tetraacetate and its salts thereof; polymer plasticizing agents, such as glycerin, disobutyl adipate, butyl stearate, and propylene glycol; ultraviolet and infrared screening and absorbing agents such as octyl salicylate, antidandruff agents such as zinc pyridinethione, and propellants such as fluorohydrocarbons, dimethyl ether, carbon dioxide, nitrogen, and LPG gas. Such optional additional components generally are used individually at levels from about 0.01% to about 10.0%, preferably from about 0.05% to about 5.0% by weight of the composition. METHOD OF MAKING The hair conditioning compositions of the present invention are preferably made by a method comprising three steps. The first step comprises mixing water, the amidoamine, and a portion of the acid at a temperature of at least 70° C. The second step comprises addition of the high melting point compound to the obtained mixture while maintaining the temperature. Agitation usually accompanies the second step. The third step comprises cooling the obtained mixture to a temperature below 60°C, wherein the remaining acid, if any, is added. Then, the low melting point oily compound, and other components are added. It has been discovered that, by changing the amount of acid included in the first step, compositions of various characteristics can be made. When from about 80% to about 100%, preferably 100% of the acid is included in the first step, a conditioning composition which provides relatively more shear-thinning property is obtained. This rheology can be recognized by the consumer as good spreadability and good rinsability. When from about up to 80%, preferably from about 50% to about 75% of the acid is included in the first step and the remainder included in the third step, a conditioning composition which provides relatively less shear-thinning property is obtained. This rheology can be recognized by the consumer as richness, and creaminess. The amount of acid to include in the first step, therefore, is determined in view of the components used in the composition according to the desired benefits of the final product.
