Sodium Polyacrylate
Approved
Absorbent Polymer; Thickener; Film Former
Also Known As
Polyacrylic Acid Sodium Salt; Sodium Acrylate Polymer
CAS Number
9003-04-07
What It Does
Thickens formulas, absorbs water, and stabilizes emulsions.
Why Oh Daisey Rates It This Way
The high-molecular-weight polymer is unlikely to penetrate intact skin. Residual acrylic acid monomers may cause irritation if manufacturing purity is inadequate; environmental persistence is a separate concern.
