GENERAL DESCRIPTION AND APPLICATIONS
Squalene is a triterpene found in human sebum and in large quantities in shark liver oil. Terpene is a class of naturally occurring various unsaturated hydrocarbons whose carbon skeletons are composed exclusively of five-carbon isoprene unit. Isoprene units are assembled and modified in thousands of ways in all living things, and are the largest group of natural products. Squalene plays a role in the biosynthesis of sterols and polycyclic terpenes. It is used in biochemical research, as a bactericide and as an intermediate in the synthesis of pharmaceuticals. Squalane is the hydrogenated form squalene and gives good penetration, spreadability, lubricity and non-oily feel. It is used as an emollient in cosmetics and skin-care products. It is used as a fixative for perfumes.

GENERAL DESCRIPTION OF TERPENE
A class of naturally occurring compounds mainly in plants as constituents of essential oils whose carbon skeletons are composed exclusively of isoprene C5 units (CH2=C(CH3)-CH=CH2). Most terpenes are hydrocarbons having molecular formula (C5H8)n in a cyclic or acyclic, saturated or unsaturated structure, while the terpenoids are oxygen-containing analogues of the terpenes such as alcohols, aldehydes or ketones containing hydroxyl groups or carbonyl groups. Several vitamines, hormones, flavour and flagrances and latex are terpenoids. Terpenes containing 30 or more carbons are usually formed by the fusion of two terpene precursors in a regular pattern, usually head-to-tail appears to be violated. They are differ from one another not only in functional groups but also in their basic carbon skeletons. Terpenes are employed mainly the fragrance and flavour purpose, as well as in the pharmaceutical and chemical industries. They are classified by the number of isoprene units:
