Cetylpyridinium chloride

Cetylpyridinium Chloride (CPC, CAS 123-03-5) is a quaternary ammonium compound classified as a cationic surfactant. It is also known under trade names such as Aktivex and Acetoquat CPC. No E-code is assigned, and it carries EC number 204-593-9.

In pharmaceutical oral care formulations, CPC disrupts microbial cell membranes, making it effective as an antiseptic active in mouthwashes and throat lozenges. In personal care, it functions as a conditioning agent by adsorbing onto negatively charged hair and skin surfaces, reducing friction and improving texture. It also serves as a preservative booster in multi-component systems.

CPC is available as a white crystalline powder conforming to Ph.Eur. and USP/NF monograph standards. It falls under REACH registration requirements for EU supply. Standard packaging includes fibre drums and multi-wall bags, with documentation available to support regulatory submissions. HS code for import classification is 2933399990.
