Chemistry, Properties & Perfumer Guide

The Chemistry

Paraffin (C15-19 alkane) is a mixture of saturated hydrocarbons derived from petroleum refining. These straight-chain alkanes are chemically inert and non-polar. The C15-19 range is selected for its optimal melting point and viscosity for cosmetic applications. Synthetic paraffins are highly purified to remove aromatic compounds.
