INCI: C15-19 Alkane
C15-19 Alkane is a mixture of straight-chain hydrocarbons with 15 to 19 carbon atoms. In modern cosmetic formulations it is typically derived from vegetable sources (sugarcane or coconut) rather than petroleum. It functions as a lightweight emollient and solvent, providing a fresh, gliding sensation on application with a powdery or soft after-feel. It is marketed as a natural, biodegradable silicone alternative.

Is C15-19 Alkane safe? Key considerations
Can C15-19 Alkane cause irritation?
Low RiskC15-19 Alkane is a stable, non-reacting hydrocarbon with low irritation potential. When derived from vegetable sources and fully refined, it is well tolerated. EU CosIng notes a restriction (II/875) regarding petroleum distillates — the full refining history must demonstrate the source material is non-carcinogenic. Vegetable-derived grades avoid this concern.
Does C15-19 Alkane increase sun sensitivity?
No RiskC15-19 Alkane does not increase photosensitivity. No sun protection precautions are required.
Is C15-19 Alkane safe during pregnancy?
SafeC15-19 Alkane is an inert hydrocarbon emollient with no systemic absorption concerns. No reproductive or developmental toxicity noted. Considered safe during pregnancy at cosmetic concentrations.
