Claims (17)

1 . A cosmetic composition, comprising

about 0.3 mass % to about 0.8 mass % of isostearic acid; about 2 mass % to about 8 mass % Sodium Hydroxypropylsulfonate Laurylglucoside Crosspolymer; about 2.5 mass % to about 5 mass % of coco-glucoside; 1 mass % to 3 mass % of cocamidopropyl betaine and at least 40 mass % of water.

2 . The cosmetic composition of claim 1 , wherein a mass ratio between the Sodium Hydroxypropylsulfonate Laurylglucoside Crosspolymer and the isostearic acid is from 2.5 to 27.

3 . The cosmetic composition of claim 1 , further comprising a taurate surfactant.

4 . The cosmetic composition of claim 3 , wherein the taurate surfactant is Sodium Methyl Cocoyl Taurate.
