Hydrogenated Polyisobutene
Hydrogenated PolyisobuteneBarrier
A clean-feeling synthetic emollient that gives long-lasting slip and shine — often used where a silicone-like feel is wanted.
What it does
Hydrogenated polyisobutene is a synthetic emollient valued for a smooth, cushiony, long-wearing glide. It softens the skin surface, adds shine to lip and balm products, and resists oxidation. It is a stable, well-tolerated feel-and-texture ingredient, not a treatment active.
