A polymer thickener. It builds gel texture and stabilizes the formula and does not affect skin.
Topical application
BLimited evidence. One RCT or several controlled studies with limitations.
A functional thickener. Safe.
Sodium Acrylic Acid/MA Copolymer (INCI: Sodium Acrylic Acid/MA Copolymer) is a synthetic polymer that works as a thickener and stabilizer. In a formula it creates a pleasant gel texture, keeps ingredients evenly dispersed and stops the product from separating. This is a functional component, not a skincare active. Its job is consistency and stability, not a direct effect on the skin, so judging it by cosmetic results does not apply. In pregnancy and breastfeeding it can be used without issue; the polymer stays on the surface and has no systemic relevance. Tolerance is good, with low irritation and allergy potential. It suits most skin types, sensitive skin included.

The Evigrade extension adds an evidence panel to iHerb, Sephora, Druni and 12 more stores. This ingredient and every other one in the product show evidence-tier, allergen risk and pregnancy/lactation flags at a glance.
Sodium Acrylic Acid/MA Copolymer is considered safe during pregnancy at typical cosmetic concentrations. Systemic absorption through the skin is minimal.
Sodium Acrylic Acid/MA Copolymer suits: normal, dry, combination, oily, sensitive.
