CHOLINE CHLORIDE
Commonly Found In
Overview
Choline chloride is the chloride salt of choline, an essential nutrient found naturally in foods. It functions as a humectant and skin conditioning agent in cosmetics. It is banned in EU and UK cosmetics (Annex II/168), though choline itself is not harmful at nutritional levels. Permitted in Japan and the US.
Also known as: (2-hydroxyethyl)trimethylammonium chloride, choline salt, vitamin B4 (non-official designation)
Key Benefits
May help attract and retain moisture in the skin due to its humectant properties. Studies on topical choline chloride for skin benefit are limited; primary use is as a humectant.
