What is AMMONIUM ACRYLOYLDIMETHYLTAURATE/BEHENETH-25 METHACRYLATE CROSSPOLYMER used for?

Viscosity controlling: Provides efficient thickening in aqueous and hydroalcoholic systems. Frequently used in gels, serums, and light creams.
Emulsion stabilizing: Offers excellent stability in the presence of electrolytes and active ingredients. Ideal for sunscreens, mineral-based products, and high-active formulas.
Film forming & texture enhancer: Improves spreadability and creates a soft, velvet-like after-feel. Common in primers, foundations, and long-wear cosmetics.

Origin

Ammonium Acryloyldimethyltaurate/Beheneth-25 Methacrylate Crosspolymer is produced synthetically through the polymerization of acryloyldimethyltaurate and beheneth-25 methacrylate monomers, then neutralized with ammonia. The long behenyl chain enhances compatibility with oils and electrolytes. It is typically supplied as a white to off-white powder that swells and thickens upon dispersion in water.
