14 Claims

1. A hair composition comprising:

(i) one or more surfactants, wherein the surfactants are selected from the group consisting of anionic and amphoteric surfactants, and mixtures thereof; and

(ii) an oil-in-water emulsion having D₅₀particle size of less than 350 nm and comprising:

a silicone mixture comprising (i) a trialkylsilyl terminated dialkylpolysiloxane having a viscosity of from 51,000 to 70,000 mPa·s at 25° C. and (ii) an amino-silicone having a viscosity of from 1,000 to 15,000 mPa·s at 25° C. and an amine value of from 2 to 10 mg of KOH per gram of amino-silicone;

a mixture of emulsifiers comprising one or more nonionic emulsifiers, wherein the mixture of emulsifiers has a HLB value from 10 to 16; and

water,

wherein the oil-in-water emulsion is present in the hair composition in a quantity ranging of from 0.1% to 15% by weight with respect to the total weight of the hair composition, and

wherein the mixture of emulsifiers comprises one or more emulsifiers chosen from:
