What is it?

Acrylates Copolymer is a synthetic polymer obtained by polymerizing acrylic monomers. In INCI: Acrylates Copolymer or Acrylates/C10-30 Alkyl Acrylate Crosspolymer (thickener-crosspolymer). It forms stable emulsions and gels over a wide pH range. The crosspolymer version (Carbomer alternative) is particularly effective at pH 5–7.

Thickener and stabilizer of emulsions in sunscreens (especially chemical UV-filter formulas), BB/CC creams, foundations, and fluid moisturizers. Provides smooth application and stay power in formulas with zinc oxide and titanium dioxide.

Key Benefits

✦

Stable texture in SPF formulas

Acrylates copolymer effectively suspends UV filters (zinc oxide, titanium dioxide) and prevents their settling. Ensures even application and stable SPF effect throughout the day.

◈

Smooth matte finish

The polymer film on the skin's surface minimizes the visibility of pores and imperfections — characteristic smooth, airbrushed effect in fluid foundation and tinted moisturizer. Moderate oil control without over-drying.

✧

Wide formulation compatibility

Stable in the presence of electrolytes, alcohols, and most actives — unlike carbomer, it does not lose viscosity when salts or acids are added. Allows for formulation over a wider pH range.
