Sodium epichlorohydrinsulfonate

Sodium epichlorohydrinsulfonate (CAS 126-83-0), also known as CHPS-Na, is a chlorinated sulfonate salt used as a reactive intermediate and functional additive in specialty chemical formulations.

It combines a reactive chlorohydrin group with a sulfonate moiety, enabling covalent bonding in polymer and surface modification processes. In personal care formulations, CHPS-Na functions as a humectant and conditioning agent.

This chemical contributes to moisture retention in skin and hair care products. Pharmaceutical manufacturers use it as a synthetic building block for active ingredients and excipient modification where controlled reactivity is required.

Its biocidal activity supports preservation applications in topical formulations where both antimicrobial efficacy and compatibility with ionic systems are needed. In polymer chemistry, it serves as a sulfonating agent.

This process introduces hydrophilic sulfonate groups onto substrates, improving surface wettability in specialty coatings. Sodium epichlorohydrinsulfonate is supplied as an aqueous solution with concentration ranging from 40% to 60%.

Pharmaceutical and personal care applications are generally sourced to technical or high-purity grades. Documentation is available to support regulatory submissions for various industrial and laboratory applications.

Bulk supply is standard for industrial users, with smaller quantities available for formulation development. This versatile intermediate ensures consistent performance across diverse chemical manufacturing sectors.
