Sodium ethanesulfonate

Sodium ethanesulfonate (CAS 5324-47-0, EC 226-194-9), also known as sodium ethylsulfonate or sodium ethanesulphonate, is an aliphatic sulfonate salt supplied as a dry powder. It carries no assigned E-code and is classified under HS code 2904.10.5000. No common abbreviation is established in trade.

In plastics and polymer processing, sodium ethanesulfonate functions as a dispersing and wetting agent, reducing interfacial tension to stabilize emulsion polymerization systems and improve pigment distribution. In textile and leather finishing, it modifies fiber surface chemistry to promote uniform dye uptake and enhance substrate wettability during wet processing stages.

Sodium ethanesulfonate is available in technical and high-purity grades as a free-flowing powder. It falls under REACH registration requirements for supply within the European Economic Area. Packaging formats typically include multi-layer bags and fiber drums; buyers should confirm grade specifications and documentation requirements directly with our technical sales team.
