Isoparaffin ingredients most frequently found cosmetics and personal care products are C13-14 Isoparaffin, Isododecane and Isohexadecane. Isoparaffins are branched-chain aliphatic hydrocarbons. The C followed by the numbers in the ingredient name represents the number of carbons in the chain. For example, C13-14 Isoparaffin is a mixture of branched-chain aliphatic hydrocarbons with 13 or 14 carbons in the chain. Isoparaffin ingredients containing aliphatic hydrocarbons with predominantly a single carbon chain length have names that represent the number of carbons in the chain.
