About this ingredient
Sodium Polyacrylate Starch is a hybrid polymer of acrylate and starch with a very high ability to absorb water. INCI: Sodium Polyacrylate Starch. In a formula it works as a thickener, stabilizer, and water absorbent: it binds large amounts of water, gives gels and creams a springy smooth texture, and keeps components suspended. It is a functional rheology component, not a skincare active. Pregnancy safety. The polymer does not penetrate skin, is systemically negligible, and there is no evidence of harm. It can be used during pregnancy and lactation. Tolerance. Irritation and allergen potential are low, suitable for sensitive skin.
