Description
Sodium Chloroacetate (CAS 3926-62-3), also known as Sodium Monochloroacetate or SMCA, is the sodium salt of chloroacetic acid. It carries no assigned E-code and is commercially referenced under abbreviations including SMA. It is registered under EC number 223-498-3 and falls within HS code 29154000.
In personal care formulations, Sodium Chloroacetate functions as an antimicrobial agent by disrupting microbial enzyme activity, inhibiting microbial growth at low concentrations. It also serves as a skin conditioning agent in topical preparations. In pharmaceutical manufacturing, it acts as a reactive intermediate in synthesising active ingredients such as amino acids and carboxymethyl derivatives.
The material is supplied as a white crystalline powder meeting industrial and pharmaceutical-grade specifications, with compliance documentation available under REACH regulation. Procurement teams should confirm grade suitability against Ph.Eur. or in-house specifications. Standard packaging formats include fibre drums and multi-wall bags, with documentation including SDS and COA supplied on request.
