Sodium cocoyl isethionate is the ester salt of coconut fatty acid and isethionic acid, a surface active agent and hair conditioner. It is present in the composition of very foaming solid shampoos. It is also highly recommended in the composition of solid soaps and make-up removers, especially if we are looking for mild formulations.

Sodium cocoyl isethionate is free of preservatives and sulfates, while being compatible with other anionic surfactants.
