Aliphatic Hydrocarbon

Description

Aliphatic hydrocarbons are a class of organic compounds consisting solely of hydrogen and carbon atoms arranged in straight or branched chains. These versatile substances play a crucial role in skincare and cosmetic formulations, primarily as emollients and solvents. Derived from petroleum or plant sources, aliphatic hydrocarbons encompass a range of molecules, including mineral oil, paraffin, and various alkanes.

In skincare products, aliphatic hydrocarbons function as occlusive agents, forming a protective barrier on the skin's surface to prevent transepidermal water loss. This property makes them effective in moisturizers and lip balms. Their low molecular weight allows for easy spreadability and a smooth, non-greasy feel on the skin.

While generally considered safe for topical use, some concerns exist regarding potential contamination with polycyclic aromatic hydrocarbons (PAHs) in petroleum-derived versions. High-quality, purified aliphatic hydrocarbons are typically used in cosmetic formulations to mitigate this risk. These ingredients are chemically inert, hypoallergenic, and resistant to oxidation, contributing to product stability and extended shelf life.

Regulatory bodies, including the FDA and EU Cosmetics Regulation, have established guidelines for the use and purity of aliphatic hydrocarbons in cosmetic products to ensure consumer safety.
