C13-15 Alkanes (Hemisqualane) are a mixture of aliphatic hydrocarbons often used in the cosmetics industry as an ingredient in skin and hair care products. They are naturally derived from waxes and vegetable oils. C13-15 Alkanes act as an emollient, meaning they form a protective film on the skin that retains moisture, prevents transepidermal water loss, and provides hydration. Due to their soothing properties, C13-15 Alkanes help soothe skin irritations. C13-15 Alkanes also help other active ingredients penetrate the skin better. These alkanes are generally considered non-comedogenic, meaning they do not clog pores or cause blackheads, making them suitable for those with acne-prone skin. In hair care products, hemisqualane provides color protection, reduces frizz, protects against heat and damage, facilitates combing and leaves hair silky smooth and soft.
