Chlorphenesin

Chlorphenesin (CAS 104-29-0) is a chlorinated glycerol ether active used as an antimicrobial and skin conditioner in cosmetic and pharmaceutical formulations. It is sold under trade names including Mycil and Adermykon, and also referenced as Clorfenesina in Spanish-language regulatory documentation. It carries no assigned E-code.

In personal care formulations, chlorphenesin functions by disrupting microbial cell membrane integrity, providing broad-spectrum activity against bacteria and fungi at low use concentrations. It is commonly incorporated into leave-on and rinse-off cosmetics as a preservative booster, often paired with other actives to extend the preservation system. In pharmaceutical topical preparations, it serves as an antifungal active ingredient.

Chlorphenesin is supplied as a solid and is subject to REACH registration requirements within the EU. Procurement teams should verify compliance with Cosmetics Regulation (EC) No 1223/2009, which restricts its use to a maximum of 0.3% in finished cosmetic products.
