Abstract

The invention relates stable, low viscosity hair care compositions having high surfactant content comprising linear sulfates (with alkyl tail of C12 and above) and branched sulfates (with alkyl tail of C12 and above), a water-miscible solvent such as dipropylene glycol or glycerin. Suitable compositions have a ratio of (Linear anionic surfactant/Branched anionic surfactant)/Miscible solvent from about 0.2 to about 5 and a viscosity of less than about 500 cP at 26.5° C.
