C9-12 Alkane is a volatile short-chain hydrocarbon from plant or petroleum feedstock. INCI: C9-12 Alkane. In a formula it works as a light dry emollient and solvent: it gives a weightless slip, evaporates quickly, and helps spread other components. It is similar in character to isododecane and serves as a plant-based replacement for volatile silicones. It is a functional sensory component, not a skincare active. It appears in sunscreens, primers, and light textures. Pregnancy safety. It evaporates quickly after application, systemic absorption is low, and there is no evidence of harm. It can be used during pregnancy and lactation. Tolerance. Irritation and allergen potential are low, and it is non-comedogenic.
