C13-15 Alkane, also known as hemisqualane is a mixture of alkanes, which are saturated hydrocarbons, and the number of carbon atoms is in the range of 13 to 15. It works as a solvent and emollient in cosmetics and also improves the texture of the cosmetic formulation. Hemisqualane is very similar to squalane, which also acts as an emollient however, hemisqualane has a lower molecular weight than squalane making it lighter.

What is C13-15 ALKANE used for?

C13-15 Alkane is mainly used as an emollient and solvent in cosmetics like skincare, body care, makeup, haircare, sun care, and other toiletry applications. It is non-comedogenic in nature. It is the perfect alternative for petroleum-based hydrocarbons like isohexadecane and low molecular weight silicone ingredients including cyclomethicone. Usage levels for this ingredient range from 1-60%.
  • Skin care: It enhances the texture of the cosmetic formulation, giving it a light-weight and non-greasy feel. It leaves the skin feeling soft and silky and is popular in sunscreens due to being compatible with ultraviolet (UV) filters. Its cleansing properties are beneficial for makeup removal, including long-wear formulas such waterproof mascara
  • Hair care: Due to a low molecular weight, it has good spreadability and does not weigh down the hair. It also reduces hair frizz


C13-15 Alkane is produced from the fermentation of sugar-based feedstock.
