A light plant-derived hydrocarbon used as a fast-spreading, dry-feeling emollient and solvent.
What it does
Undecane is a light hydrocarbon, often plant-derived and paired with tridecane. It spreads quickly, leaves a dry, silky feel, and can dissolve oily ingredients, so it is used as a volatile emollient and plant-based alternative to light silicones. It is a texture ingredient rather than a skin active.
