BETA-SITOSTERYL (OCTADECENE/MA) COPOLYMER
Description
Beta-sitosteryl (octadecene/MA) copolymer is a novel skincare ingredient that combines the benefits of plant-derived beta-sitosterol with a synthetic copolymer. This unique compound functions as an emollient and film-forming agent in various cosmetic formulations. The beta-sitosterol component, derived from plant sources, exhibits anti-inflammatory and antioxidant properties, potentially aiding in skin soothing and protection against environmental stressors.
The octadecene/maleic anhydride (MA) copolymer portion of the ingredient provides excellent film-forming capabilities, creating a smooth, non-greasy barrier on the skin's surface. This barrier helps to lock in moisture and protect against transepidermal water loss, promoting improved skin hydration and a more supple appearance.
Beta-sitosteryl (octadecene/MA) copolymer is particularly effective in leave-on skincare products such as moisturizers, serums, and sunscreens. Its film-forming properties may enhance the longevity and efficacy of other active ingredients in the formulation. Additionally, this ingredient can contribute to improved texture and spreadability of products, enhancing the overall user experience. While generally well-tolerated, as with any skincare ingredient, individual sensitivities may vary, and patch testing is recommended for those with sensitive skin.
