BEHENYL METHACRYLATE/T-BUTYL METHACRYLATE COPOLYMER
Description
Behenyl Methacrylate/t-Butyl Methacrylate Copolymer is a synthetic polymer used in cosmetic and skincare formulations. This ingredient functions primarily as a film-forming agent and viscosity controller. Its unique structure, combining long-chain behenyl groups with the rigidity of t-butyl components, provides both flexibility and durability to skincare products.
In cosmetic applications, this copolymer contributes to the formation of a smooth, even film on the skin's surface. This film helps to lock in moisture and other beneficial ingredients, potentially enhancing the efficacy of active components in the formulation. The t-butyl methacrylate portion of the polymer adds resistance to oil and water, improving the wear and longevity of the product.
As a viscosity controller, it helps stabilize emulsions and suspensions, ensuring consistent texture and preventing separation of ingredients. This property is particularly valuable in sunscreens, foundations, and other products requiring uniform application and extended wear time.
While generally considered safe for topical use, it's important to note that this ingredient is not penetrative and remains on the skin's surface. It is non-comedogenic and suitable for various skin types, including sensitive skin.
