Poly(vinylsulfonic acid) sodium salt

Poly(vinylsulfonic acid) sodium salt (CAS 25053-27-4), also known as sodium poly(ethylenesulfonate), is a water-soluble anionic polyelectrolyte used across industrial processing and formulation.

It functions as a dispersant, scale inhibitor, and surface modifier in aqueous systems where charge-based stabilization is required. In water treatment, it inhibits scale formation and disperses particles.

The compound is highly effective in cooling water circuits and industrial effluent systems. Textile and paper manufacturers apply it as a surface modifier to improve wettability and dye uptake on substrates.

In leather processing, it aids tanning bath dispersion and controls the rheology of processing liquors. Home care and industrial cleaning formulations incorporate it to prevent soil redeposition.

The additive helps stabilize surfactant systems at varying pH levels. Poly(vinylsulfonic acid) sodium salt is supplied as an aqueous solution, with concentration typically ranging from 25% to 35% by weight.

Technical grade is the standard commercial offering, with molecular weight variants available to suit specific viscosity and charge density requirements for diverse industrial applications.

Packaging options generally include drums and intermediate bulk containers for industrial supply volumes. This ensures safe handling and efficient transport for large-scale manufacturing operations.
