Isododecane
Isododecane is a lightweight, fast-drying emollient and solvent commonly used in UK beauty products such as mascaras, foundations, lipsticks and primers. It gives formulas a silky, non-greasy feel and helps them spread easily while improving wear time. Shoppers often see it in long-wear and waterproof cosmetics.
How it works in skincare
In cosmetics and skincare Isododecane acts as a volatile silicone alternative, evaporating quickly after application to leave behind a smooth, breathable film. It improves the spreadability of pigments and waxes, prevents settling in liquid formulas, and enhances the overall texture so products feel weightless on skin or lips while boosting their staying power.
