Acrylates Copolymer is a class of synthetic copolymers composed of acrylic acid, methacrylic acid, and their esters, often presenting as a fine powder or beads suited for cosmetic formulation. In skincare, it excels as a film-forming agent that creates a smooth, soft barrier on the epidermis, lending a tactile “slip” while reducing transepidermal water loss. It also functions as a texture enhancer and thickener, improving the viscosity, spreadability, and stability of emulsions, gels, and sunscreens. Additionally, its film-forming capacity contributes water‑resistance, making it valuable in waterproof skincare and sun-protection formulas.
In haircare applications, Acrylates Copolymer serves as a film former and styling aid, imparting hold and shape while smoothing the hair shaft and aiding detangling. Its inherent barrier properties lend water-resistant durability, an asset in styling products like mousses, gels, and conditioners that must preserve structure even in humid or moist environments.
Quick Insights

Manufacturers crafting durable, high-performance skincare and haircare products — particularly those requiring texture appeal, water resistance, or smoothing finishes.
Also Known As:
Acrylates Copolymer (INCI), a synthetic polymer formed from acrylic and methacrylic acid monomers — even if trade names vary, this is the standardized cosmetic-listed name.
Safety Analysis
According to the Cosmetic Ingredient Review (CIR), Acrylates Copolymer is “safe for use in cosmetics when formulated to avoid irritation,” though the complete spectrum of irritation potential, especially in high concentrations, relies on robust formulation and context . While generally low-hazard per EWG, the ingredient raises contamination flags due to potential residual monomers such as acrylic acid, methacrylic acid, or benzene. This emphasizes the importance of sourcing high-purity grades and verifying regulatory compliance. Furthermore, CIR and regulatory bodies permit its use provided formulation controls and appropriate concentration levels are maintained . Patch testing and stability trials are recommended to ensure tolerance and safety.
