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.

Where is Sodium epichlorohydrinsulfonate used?

• Personal care: humectant and conditioning agent that contributes to moisture retention in skin and hair care
• Pharmaceuticals: synthetic building block for active ingredients and excipient modification where controlled reactivity is required
• Preservation: biocidal activity in topical formulations compatible with ionic systems
• Polymer chemistry: sulfonating agent that introduces hydrophilic sulfonate groups onto substrates
• It combines a reactive chlorohydrin group with a sulfonate moiety, enabling covalent bonding in polymer and surface modification processes.

Commercial specifications

• Aqueous solution, concentration 40% to 60%
• Technical or high-purity grades for pharmaceutical and personal care applications
• Documentation supports regulatory submissions
• Bulk supply standard; smaller quantities for formulation development
