Acrylates/C10-30 Alkyl Acrylate Crosspolymer

Acrylates/C10-30 Alkyl Acrylate Crosspolymer is a synthetic, crosslinked acrylic acid copolymer hydrophobically modified with long-chain (C10-30) alkyl groups, best known under Lubrizol's Pemulen TR-1 and TR-2 trade names. Its amphiphilic architecture allows it to simultaneously stabilize oil-in-water emulsions and build viscosity at remarkably low use levels (typically 0.1–0.5%), making it a dual-function emulsifier-rheology modifier that can replace traditional emulsifier blends. Formulators prize it for enabling lightweight, non-greasy fluid emulsions with high oil-phase tolerance (up to 25–30% oil) and excellent long-term stability, while its acid-swellable nature means the final texture and viscosity are precisely controlled through neutralization pH.
