Rheology Modifiers & Thickeners

Rheology modifiers adjust the viscosity, flow, and texture of cosmetic formulations. Synthetic thickeners include carbomers (cross-linked polyacrylic acid), acrylates copolymers, and polyurethanes. Natural thickeners include xanthan gum, carrageenan, guar gum, and cellulose derivatives (hydroxyethyl cellulose, hydroxypropyl cellulose). Regulatory scrutiny focuses on monomer residues in synthetic polymers and microplastic concerns under the EU Commission Regulation 2023/2055 (effective October 2023, with staggered compliance dates through 2035). This hub lists rheology modifier ingredients with their safety ratings and regulatory references.
