Sodium acrylate

Sodium acrylate (CAS 7446-81-3, EC 231-209-7), also known as sodium propenoate and acrylic acid sodium salt, is the sodium salt of acrylic acid supplied in anhydrous solid form. It carries no E-code designation and is classified under HS code 29161100 within the monomers and building blocks category.

In superabsorbent polymer production, sodium acrylate undergoes free-radical polymerization to form crosslinked networks capable of absorbing several hundred times their weight in water, making it the backbone of hygiene and agricultural gel applications. In water treatment, it functions as a coagulation and flocculation aid, neutralizing charged particulates to accelerate settling.

This material is registered under REACH and available in anhydrous solid grades suitable for industrial polymerization and personal care formulation. Standard packaging formats for B2B supply include 25 kg bags and bulk quantities. Buyers should confirm grade specifications against application requirements prior to procurement.
