[0010] Conditioning Gel Phase The compositions of the present invention comprise a conditioning gel phase, which comprises (a) a cationic surfactant and (b) a fatty alcohol.

[0011] Preferably, the cationic surfactant is of the formula N + (R 1 )(R 2 )(R 3 )(R 4 ) and R 1 , R 2 , R 3 and R 4 are independently (C1~C 30 ) alkyl or benzyl.

[0012] Preferably, R 1 , R 2 , R 3 and R 4 One, two or three of the following may be independently selected from (C4 to C 30 ) alkyl, and other R 1 , R 2 , R 3 and R 4 The group is (C1-C6) alkyl or benzyl.

[0013] More preferably, R 1 , R 2 , R 3 and R 4 One or two of the following may be independently selected from (C6 to C 30 ) alkyl, and other R 1 , R 2 , R 3 and R 4The group is a (C1-C6) alkyl or benzyl group. Optionally, the alkyl group can contain one or more ester (-OCO- or -COO-) and / or ether (-O-) linkages within the alkyl chain. The alkyl group can be substituted with one or more hydroxyl groups. The alkyl group can be linear or branched, and in the case of alkyl groups having three or more carbon atoms, can be cyclic. The alkyl group can be saturated or can contain one or more carbon-carbon double bonds (e.g., oleyl). The alkyl group can be ethoxylated with one or more ethyleneoxy groups on the alkyl chain.

[0014] Cationic surfactants suitable for use in the conditioner compositions of the present invention include cetyltrimethylammonium chloride, behenyltrimethylammonium chloride, cetylpyridinium chloride, tetramethylammonium chloride, tetraethylammonium chloride, octyltrimethylammonium chloride, dodecyltrimethylammonium chloride, hexadecyltrimethylammonium chloride, octyldimethylbenzylammonium chloride, decyldimethylbenzylammonium chloride, stearyldimethylbenzylammonium chloride, didodecyldimethylammonium chloride, dioctadecyldimethylammonium chloride, tallowtrimethylammonium chloride, dihydrogenated tallowdimethylammonium chloride (e.g., Arquad 2HT / 75 from AkzoNobel), cocotrimethylammonium chloride, PEG-2-oleammonium chloride, and their corresponding hydroxides. Further suitable cationic surfactants include materials having the CTFA designations Quaternium-5, Quaternium-31, and Quaternium-18. Mixtures of any of the foregoing materials may also be suitable. A particularly useful cationic surfactant for use in conditioners according to the invention is cetyltrimethylammonium chloride, commercially available, for example, as GENAMIN CTAC (e.g., Hoechst Celanese). Another particularly useful cationic surfactant for use in conditioners according to the invention is behenyltrimethylammonium chloride, commercially available, for example, as GENAMIN KDMP (e.g., Clariant). Preferably, the cationic surfactant is selected from cetyltrimethylammonium chloride, behenyltrimethylammonium chloride, and mixtures thereof.

[0015] Another example of a class of cationic conditioning surfactants suitable for use in the present invention includes the following (i) and (ii), either alone or in admixture with one or more other cationic conditioning surfactants: (i) General formula (I): [ka] (In the formula, R 1 is a hydrocarbyl chain having 10 or more carbon atoms, and R 2 and R 3 are independently selected from hydrocarbyl chains of 1 to 10 carbon atoms, and m is an integer from 1 to about 10; and (ii) Acid It is a combination of:

[0016] As used herein, the term hydrocarbyl chain means an alkyl chain or an alkenyl chain.

[0017] Preferred amidoamine compounds are R 1 is a hydrocarbyl residue having from about 11 to about 24 carbon atoms; R 2 and R 3 are each independently a hydrocarbyl residue, preferably an alkyl group, having from 1 to about 4 carbon atoms; It corresponds to formula (I) where m is an integer from 1 to about 4.

[0018] Preferably, R 2 and R 3 is a methyl group or an ethyl group.

[0019] Preferably, m is 2 or 3, ie, an ethylene or propylene group.

[0020] Preferred amidoamines useful herein include stearamidopropyl dimethylamine, stearamidopropyl diethylamine, stearamidoethyl diethylamine, stearamidoethyl dimethylamine, palmitamidopropyl dimethylamine, palmitamidopropyl diethylamine, palmitamidoethyl diethylamine, palmitamidoethyl dimethylamine, behenamidopropyl dimethylamine, behenamidopropyl diethylamine, behenamidoethyl diethylamine, behenamidoethyl dimethylamine, arachidamidopropyl dimethylamine, arachidamidopropyl diethylamine, arachidamidoethyl diethylamine, arachidamidoethyl dimethylamine and mixtures thereof.

[0021] Particularly preferred amidoamines useful herein are stearamidopropyl dimethylamine, stearamidoethyl diethylamine, and mixtures thereof.

[0022] Commercially available amidoamines useful herein include stearamidopropyl dimethylamine available under the tradename LEXAMINES-13 from Inolex (Philadelphia, PA, USA) and AMIDOAMINE MSP from Nikko (Tokyo, Japan), stearamidoethyl diethylamine available under the tradename AMIDOAMINE S from Nikko, behenamidopropyl dimethylamine available under the tradename INCROMINE BB from Croda (North Humberside, UK), and various amidoamines under the tradename SCHERCODINE series available from Scher (Clifton, NJ, USA).

[0023] The acid (ii) may be any organic or mineral acid capable of protonating the amidoamine in the conditioner composition. Suitable acids useful herein include hydrochloric acid, acetic acid, tartaric acid, fumaric acid, lactic acid, malic acid, succinic acid, and mixtures thereof. Preferably, the acid is selected from the group consisting of acetic acid, tartaric acid, hydrochloric acid, fumaric acid, and mixtures thereof.

[0024] The primary role of the acid is to protonate the amidoamine in the hair treatment composition, thus generating a tertiary amine salt (TAS) in situ in the hair treatment composition. A TAS is actually a non-permanent quaternary ammonium or pseudo-quaternary ammonium cationic surfactant.

[0025] Preferably, the acid is included in an amount sufficient to protonate all of the amidoamine present, i.e., at a level that is at least equimolar to the amount of amidoamine present in the composition.

[0026] In conditioners for use in the present invention, the level of cationic conditioning surfactant will generally be in the range of from 0.01 to 10%, more preferably from 0.05 to 7.5%, and most preferably from 0.1 to 5% of the total weight of cationic conditioning surfactant based on the total weight of the composition.

[0027] The conditioners used in the present invention also incorporate fatty alcohols. The combined use of fatty alcohols and cationic surfactants in the conditioning composition is believed to be particularly advantageous because it results in the formation of a lamellar phase in which the cationic surfactant is dispersed.

[0028] Representative fatty alcohols contain 8 to 22 carbon atoms, more preferably 16 to 22 carbon atoms. Fatty alcohols are typically compounds containing a straight-chain alkyl group. Examples of suitable fatty alcohols include cetyl alcohol, stearyl alcohol, and mixtures thereof. The use of these materials is also advantageous in that they contribute to the overall conditioning properties of the compositions used in the present invention.

[0029] The level of fatty alcohol in conditioners for use in the present invention ranges from 0.01 to 10% by weight of the composition, preferably 0.1 to 8%, more preferably 0.2 to 7%, and most preferably 0.3 to 6%. The weight ratio of cationic surfactant to fatty alcohol is suitably 1:1 to 1:10, preferably 1:1.5 to 1:8, and optimally 1:2 to 1:5. If the weight ratio of cationic surfactant to fatty alcohol is too high, it may cause eye irritation from the composition. If it is too low, it may cause a squeaky feeling in the hair of some consumers.

[0030] Oil emulsion The composition of the present invention comprises an oil emulsion comprising (c) a mixture of triglyceride oils, (d) a cationic emulsifier, and (e) water.

[0031] The oil emulsion is within the overall gel phase emulsion, i.e. the oil emulsion and gel phase are separate emulsions.

[0032] (c) triglyceride oil mixture The compositions of the present invention include a mixture of triglyceride oils.

[0033] Suitable triglyceride oils are fatty acid esters characterized by having at least 8 carbon atoms, including esters with hydrocarbyl chains derived from fatty acids or alcohols. Monocarboxylic acid esters include esters of alcohols and / or acids of the formula R'COOR, where R' and R independently represent alkyl or alkenyl groups. Di- and tri-alkyl and alkenyl esters of carboxylic acids can also be used. Particularly preferred fatty acid esters are mono-, di-, and triglycerides, more specifically, mono-, di-, and triesters of glycerol and long-chain carboxylic acids.

[0034] The mixture of triglyceride oils is present in an amount of 0.1 to 5%, preferably 0.5 to 4%, more preferably 1 to 3% by weight of the total composition.

[0035] The mixture of triglyceride oils comprises: i) at least one first oil having an average chain length distribution of C8 to C14; and ii) at least one second oil having an average chain length distribution of C16 to C22.

[0036] Preferred first oils are selected from palm kernel oil, macauba almond oil, and coconut oil, most preferably coconut oil.

[0037] Preferred second oils are selected from macauba pulp oil, safflower oil, soybean oil, sunflower oil, olive oil and moringa oil, most preferably moringa oil.

[0038] The mixture of oils preferably contains 2 to 10 oils, more preferably 2 to 5 oils, and most preferably 2 oils.

[0039] Preferably, the mixture of triglyceride oils contains only two oils: coconut oil and moringa oil.

[0040] The ratio of the first oil to the second oil is preferably 1:1 to 12:1, preferably 3:1 to 10:1, more preferably 5:1 to 10:1, and most preferably 8:1 to 10:1.

[0041] (b) Cationic emulsifier The cationic emulsifier may be any suitable cationic emulsifier.

[0042] Preferably, the cationic emulsifier is a cationic surfactant. When the cationic emulsifier is a cationic surfactant, it may be the same as or different from the cationic surfactant (a) (described above) in the conditioning gel phase. Preferably, it is the same.

[0043] The cationic emulsifiers may be protonated or non-protonated. Preferred examples of protonated cationic emulsifiers are amidoamines.

[0044] Preferred examples of non-protonated cationic emulsifiers include quaternary amine salts having 12 to 24 carbon atoms, preferably 16 to 22. Preferred quaternary ammonium salts are selected from behenyltrimethylammonium chloride (BTAC), behentrimonium methosulfate, cetyltrimethylammonium chloride, and mixtures thereof, most preferably behenyltrimethylammonium chloride (BTAC).

[0045] The compositions of the present invention are silicone-free. In the context of the present invention, "silicone-free" means that the silicone content is less than 0.4 wt. % based on the weight of the total composition, more preferably less than 0.25 wt. %, even more preferably less than 0.1 wt. %, even more preferably less than 0.05 wt. %, even more preferably less than 0.001 wt. %, even more preferably less than 0.0001 wt. %, and most preferably 0 wt. %.

[0052] Embodiments of the present invention are provided in the following examples, in which all percentages are quoted by total weight unless otherwise stated. [Example]

[0053] Example 1: Compositions 1 to 3 according to the present invention and comparative compositions A and B Five hair conditioner formulations were prepared, the compositions of which are shown in Table 1.

[0054] Table 1: Compositions of conditioners 1 to 3 according to the present invention and comparative compositions A and B [Table 1]

[0055] The formulation was made by adding the cationic surfactant to the fatty alcohol and stirring at 85°C. This mixture was slowly added to water, typically at 55°C, until the mixture reached a temperature of 60°C. This temperature was maintained with stirring for 30 minutes. More water was then added to cool the mixture to room temperature. The remaining ingredients (oil emulsified with emulsifier and water) were added and stirred, with external cooling if necessary.

[0056] Example 2: Treatment of hair with compositions 1 to 3 and comparative compositions A and B The hair used was dark brown European hair weighing 0.25 g and 5 cm in length.

[0057] Hair was treated with each composition as follows:

[0058] First, hair was treated with a cleansing shampoo using the following method.

[0059] The hair fibers were wetted and 0.1 mL of shampoo was applied per gram of hair and rubbed into the hair for 30 seconds. The hair was rinsed for 30 seconds and the shampooing step was repeated. It was then rinsed for 30 seconds.

[0060] Wet hair was then treated with conditioner 1-3, A, or B in the following manner.

[0061] The conditioner was applied to wet hair at a rate of 0.2 g per gram of hair and massaged in for 1 minute. The hair was rinsed for 1 minute to remove excess water. The hair was allowed to dry at room temperature overnight.

[0062] Five replicate hair switches were prepared for each conditioner.

[0063] Example 3: Conditioning properties of hair treated with compositions 1-3 and comparative compositions A and B The level of friction on the hair can be used as an indicator of the level of lubricity imparted by the conditioning treatment.

[0064] The friction of dry hair tresses was measured using a texture analyzer (Stable Microsystems Texture Analyser XT Plus, manufactured by Stable Micro Systems Ltd., Godalming, Surrey, UK). Experiments were carried out under controlled temperature and humidity (20°C, 50% relative humidity).

[0065] The results are shown in Table 2.

[0066] Table 2: Coefficient of friction (average of five) for hair treated with compositions 1-3 and comparative compositions A and B [Table 2]

[0067] The compositions according to the invention are found to provide low friction to the hair.
