What is Sodium cocoyl isethionate?
Chemical properties
Sodium cocoyl isethionate is the Sodium salt of the coconut fatty acid ester of Sisethionic acid which functions as a surfactant-cleansing agent (Nikitakis, 1988).
Sodium cocoyl isethionate is in the form of a fine white powder that consists of active ingredient plus minor impurities and has a mild odor (Estrin et al., 1982b). Sodium Cocoyl lsethionate i s stable at a pH of 6-8 and hydrolyzes outside of this pH range (Hunting, 1983).
The Uses of Sodium cocoyl isethionate
sodium cocoyl isethionate is a mild, high-foaming surfactant. It leaves the skin with a soft afterfeel, which is why it is sometimes referred to as "baby foam". This compound is a good sulfate-free alternative for people who want to avoid commonly known surfactants such as sodium lauryl sulfate (SLS).
What are the applications of Application
Sodium cocoyl isethionate is used as a surfactant-cleansing agent in cosmetic formulations. It is slightly to practically nontoxic, with an oral LD50 of 24.33 g/kg for rats. Dermal application of 1.0-36.0% w/w aqueous Sodium Cocoyl lsethionate to rats for 28 days did not produce any significant toxic effects.
Preparation
Sodium Cocoyl lsethionate is preparedvia the following reaction: sodium isethion- ate is reactedwith either the fatty acid mixture from coconut oil (Hoffmann, 1990)or the corresponding chlorides to form Sodium Cocoyl lsethionate (Hunting, 1983). The sodium isethionate was first prepared by adding 1 mole of ethylene oxide to sodium bisulfite.
Flammability and Explosibility
Non flammable
Safety
The Cosmetics Ingredient Review has deemed the ingredient safe for use in cosmetic products when formulated to be non irritating. Whole Foods has deemed the ingredient acceptable in its body care quality standards. Clinical research has shown that the ingredient is typically not a skin irritant or sensitizer.
