Compatibility

Works well with:
Glycerin Niacinamide Hyaluronic Acid Propylene Glycol Phenoxyethanol Panthenol

Use caution with:
High concentrations of electrolytes Cationic surfactants

Acrylates Copolymer can be sensitive to high electrolyte concentrations, which may disrupt the polymer network and reduce viscosity or film integrity. Cationic ingredients such as quaternary ammonium compounds can cause precipitation or flocculation due to charge interactions. Formulators should evaluate compatibility when combining with salts, acids at high levels, or cationic actives.

Formulation notes

Acrylates Copolymer is a synthetic polymer used primarily as a film-former, thickener, and stabilizer in cosmetic formulations including sunscreens, foundations, serums, and hair care products. It forms a flexible, water-resistant film on skin or hair surfaces, improving wear, texture, and product aesthetics. It is generally considered safe for cosmetic use, but formulators should note that the CAS number may vary by specific monomer composition and supplier grade.
