Hydrogenated Polyisobutene
Hydrogenated Polyisobutene is a lightweight, silky emollient commonly used in UK skincare and makeup to give products a smooth, non-greasy feel. It helps soften skin and improve the spreadability of creams, serums, lipsticks and foundations. A synthetic ingredient derived from petroleum, it is valued for its ability to lock in moisture without feeling heavy.
How it works in skincare
In cosmetics and skincare, Hydrogenated Polyisobutene functions as an emollient and skin-conditioning agent. It forms a breathable film on the skin’s surface that helps reduce transepidermal water loss while giving formulas a luxurious, velvety texture. Because it is highly compatible with both oils and silicones, it is frequently used to improve the glide and finish of lip products, facial moisturisers, sunscreens and colour cosmetics without leaving a sticky or oily residue.

Hydrogenated Polyisobutene is a fully synthetic ingredient produced by the hydrogenation of polyisobutene, which itself is derived from the polymerization of isobutene obtained from petroleum refining.
