Hydrogenated Polybutene

What is Hydrogenated Polybutene?

Hydrogenated Polybutene is a synthetic, saturated hydrocarbon polymer created by hydrogenating polybutene, which derives from polymerized isobutylene monomers. Commonly found in lip care products, foundations, and glosses, it serves in makeup and skincare formulations. It functions by adhering particles together for cohesive structures in solids like powders and bars, while also thickening or thinning formulas to achieve ideal flow, spreadability, and suspension of other components. This enhances overall product integrity, prevents ingredient separation, and delivers a smooth, glossy finish without greasiness. Its stability resists oxidation, making it reliable in various textures from creams to sticks.
