Shower gel compositions in the form of a liquid or gel comprising 5-50% wt. of a detergent comprising 30-100% wt. (on total detergent) of a fatty acyl isethionate and 0-70% wt (on total detergent) of other detergent, 0.01-5% on product of cationic polymer and 0.5-15% wt. by weight of silicone. The compositions show enhanced silicone deposition as compared with composition employing other surfactants.

Detergent composition

This invention involves a method for determining silicone deposition enhancing cationic polymers to be formulated into silicone-containing formulations which comprises the steps of preparing a composition having an anionic surfactant, an amphoteric surfactant, silicone, and a cationic polymer, diluting that composition, and making a positive determination if flocculation occurs within three days.
