ACRYLIC ACID/ETHYLTRIMONIUM CHLORIDE METHACRYLATE COPOLYMER
Description
Acrylic Acid/Ethyltrimonium Chloride Methacrylate Copolymer is a synthetic polymer used in various cosmetic and personal care formulations. This versatile ingredient functions primarily as a film-forming agent and hair fixative. Its unique chemical structure combines the properties of acrylic acid and quaternary ammonium compounds, resulting in a copolymer with both anionic and cationic characteristics.
In skincare products, this copolymer acts as a stabilizer and thickening agent, improving the texture and consistency of formulations. It also enhances the adherence of active ingredients to the skin, potentially increasing their efficacy. In hair care applications, it provides hold and style retention while imparting a smooth, non-sticky feel.
The ingredient demonstrates good compatibility with a wide range of cosmetic ingredients and is stable across various pH levels. It is particularly effective in water-based formulations and can contribute to the creation of clear gels and lotions. While generally considered safe for topical use, some individuals may experience mild irritation, particularly those with sensitive skin.
Formulators often utilize this copolymer in concentrations ranging from 0.5% to 5%, depending on the desired effect and product type. Its multifunctional nature makes it a valuable component in products such as styling gels, hair sprays, facial serums, and moisturizers.
