Isoparaffin is a type of branched-chain paraffin or alkane (acyclic saturated hydrocarbon), consists of only carbon and hydrogen atoms. The C followed by the numbers in the ingredient name represents the number of carbons in the chain. Thus, C13-14 isoparaffin is a mixture of branched-chain aliphatic hydrocarbons with 13 or 14 carbons in the chain. Since the hydrogen and carbon atoms are arranged in a tree structure, they are useful for attaching more active functional groups of biological molecules. Cosmetic products that contain C13-14 isoparaffin includes moisturizers, foundations, sun care products, lip products, deodorants and antiperspirants, makeup removers, and hair care products.
