Policosanol is a mixture of primary long-chain aliphatic(non-ring) alcohols. The main ingredient in policosanol is octacosnaol, but as the name implies, Sometimes, a little amount of individual alcohol like Heptacossanol and Nonocosanol exists in waxes. But in general, effective components can be analyzed including Tetracosanol, Hexacosanol and Dotriacontanol.Policosanol is a group of active compounds composed of predominantly five higher primary aliphatic alcohols-tetracosanol, hexacosanol, octacosanol, triacontanol and dotriacontanol.
