The smaller molecules are used in Cosmetics and food, and as industrial Solvent s. Some of the larger molecules are important as Biofuel s.
Due to their Amphipathic nature, fatty alcohols behave as nonionic Surfactant s. They find use as Emulsifier s, Emollient s and Thickener s in Cosmetics and Food Industry .
Fatty alcohols are a common component of Wax es, mostly as Ester s with Fatty Acid s but also as alcohols themselves.
Those with common names include:
- Capryl Alcohol (1-octanol) -- 8 carbon atoms
