This invention relates to hair care compositions containing a branched organopolysiloxane, 'oil in water' emulsion. Despite the prior art, there still exists the opportunity to increase the benefits delivered through conditioning hair care compositions. A particular need exists for hair care compositions which can deliver enhanced silicone deposition, especially to the damaged parts of the hair. It is therefore an object of the present invention to provide a hair care composition which can deliver enhanced silicone deposition onto the hair, in particular damaged hair. It has been found that this can be achieved by a hair care composition comprising a conditioning gel phase with an aqueous emulsion of a branched organopolysiloxane comprising an aqueous continuous phase of water and a cationic surfactant or a blend of non-ionic and cationic surfactants and a dispersed phase of the branched organopolysiloxane and a hydrocarbon oil, and the aqueous emulsion having a particle size of 5 to less than 12 microns Dv(50).

Hair conditioning composition

A hair care composition obtainable by blending a conditioning gel phase with an aqueous emulsion of a non-linear organopolysiloxane comprising monomer units of silsesquioxane having a formula (RSiO)where n=1, R is an alkyl group, preferably methyl, ethyl or propyl, and copolymer segments of polydialkylsiloxane; the conditioning gel phase being formed from a cationic surfactant, a high melting point (25&#xb0; C. or higher) fatty compound and an aqueous carrier; and the aqueous emulsion of the non-linear organopolysiloxane having an aqueous continuous phase consisting of water and a blend of non-ionic and cationic surfactants and a dispersed phase consisting of the non-linear organopolysiloxane and a hydrocarbon oil, wherein the weight ratio of the non-linear organopolysiloxane to the hydrocarbon oil is 40:60 to 65:35. Alternatively, the aqueous continuous phase consists of water and a cationic surfactant.

The invention provides a hair care composition obtainable by blending a conditioning gel phase with an aqueous polydimethylsiloxane polymer emulsion; the conditioning gel phase being formed from a cationic surfactant, a high melting point (25&#xb0; C. or higher) fatty compound and an aqueous carrier; and the aqueous polydimethylsiloxane polymer emulsion having an aqueous continuous phase consisting of water and a blend of nonionic and cationic surfactants and a dispersed phase consisting of a polydimethylsiloxane polymer and a hydrocarbon oil, wherein the polydimethylsiloxane polymer has a dynamic viscosity of 50,000 to 110,000 cP at 25&#xb0; C., and the hydrocarbon oil has a kinematic viscosity of 1 to 35 cSt at 40&#xb0; C. and a specific gravity of 0.76 to 0.87 at 25&#xb0; C., and the weight ratio of the polydimethylsiloxane polymer to the hydrocarbon oil is 45:55 to 70:30.

Hair care composition comprising polydimethylsiloxane polymer emulsion

A kit for cleansing hair comprising: &#x2022; a) a dry shampoo, in which the dry shampoo comprises a particulate material, preferably aluminum octenyl succinate starch or rice starch, preferably in the form of an aerosol; and &#x2022; b) a substrate, preferably a flexible sheet comprising a non-woven material, preferably comprising cellulose fiber or polyester fiber and mixtures thereof, the substrate comprising a surfactant selected from the group consisting of nonionic, anionic, amphoteric and mixtures thereof.

Hair cleaning kit

A method of treating hair comprising the step of applying to dry towel dried hair a hair care product comprising a non-surfactant esterified sugar which is non-crystalline at 20&#xb0; C.

Hair care method

A composition for personal, home, or laundry treatment comprising a polymer made up of one or more crosslinked rake or comb silicone copolymer segments. A process for making copolymers for use in such compositions involves hydrosilylation in the presence of a catalyst.
