Comedogenic Risk

None

Not typically evaluated for comedogenicity — no standardized rating available.

Is Ammonium Polyacryloyldimethyl Taurate a Good Ingredient?

Rated Good because it reliably builds viscosity and stabilizes emulsions at low use levels, improving slip and uniformity without adding heaviness. It is generally inert and low‑irritating in well‑formulated products.

Skin Benefits

Improves glide for a smoother application and a more even feel on skin. Helps formulas remain cohesive so textures stay consistent during wear.

Uses in Skincare & Cosmetics

Common in gel-cream moisturizers, sunscreens, and liquid foundations to create a structured, non-runny consistency. Also used in micellar cleansers to build soft gel networks.

Safety

Typically well tolerated and non-sensitizing; irritation is uncommon. As with most film-forming thickeners, very high levels may feel tight or dry on some skin types.
