Water-free/anhydrous cream shampoo
View Patent ↗An anhydrous shampoo composition includes two surfactants selected from (a) sodium cocoyl isethionate, and (b) at least one of sodium lauroyl methyl isethionate and sodium cocoyl methyl isethionate; and propanediol. The compositions can further include glycerin, gaur and citric acid. The shampoos compositions are capable of foaming when combined with water during use for cleaning and conditioning keratinous fibers.
