Sodium 3-chloro-2-hydroxypropanesulfonate

Sodium 3-chloro-2-hydroxypropanesulfonate, commonly abbreviated as CHPS-Na, is an organosulfonate salt registered under CAS 126-83-0 and EC 204-807-0. It carries no assigned E-code. The compound is commercially recognised under the shorthand CHPS-Na across personal care and pharmaceutical supply chains.

In cosmetic formulations, CHPS-Na functions as an antimicrobial agent by disrupting microbial cell membranes, extending product shelf life without relying on traditional preservative systems. It also acts as a skin conditioner and humectant, attracting and retaining moisture within the stratum corneum. Pharmaceutical manufacturers use it as an intermediate in synthesising active compounds requiring a chlorohydrin or sulfonate functional group.

CHPS-Na is supplied as a powder to crystalline solid and falls under HS code 29055900 for customs classification. Procurement should confirm REACH compliance documentation and supplier-specific certificates of analysis prior to purchase. Regulatory alignment with Ph.Eur. or FCC standards depends on intended application and should be verified with the supplying manufacturer.
