POLY ISO BUTENE

POLY ISO BUTENE About

Polyisobutene is a synthetic polymer widely used in cosmetic and personal care formulations as an emollient, film-forming agent, binder, viscosity modifier, and texture enhancer. It is available in different molecular-weight grades, ranging from low-viscosity liquids to more viscous materials, allowing formulators to select the appropriate grade for specific applications. Polyisobutene provides excellent lubricity and gives formulations a smooth, silky, non-tacky feel. It forms a flexible protective film on the skin that helps reduce moisture loss and leaves the skin feeling soft and conditioned. It is particularly useful in color cosmetics because of its ability to improve pigment dispersion, adhesion, gloss, and product spreadability. Polyisobutene is commonly used in lipsticks, lip glosses, lip balms, foundations, mascaras, creams, lotions, sunscreens, and anhydrous formulations. It also improves the texture and consistency of products while contributing to water resistance and long-lasting performance. The ingredient is compatible with many oils, waxes, esters, pigments, and other cosmetic raw materials, making it highly versatile in formulation development.
