PETROLEUM DISTILLATES

Description

Petroleum distillates are a group of hydrocarbon-based substances derived from the refining of crude oil. These versatile ingredients are commonly used in various skincare and cosmetic formulations due to their emollient and occlusive properties. The distillation process separates crude oil into different fractions, resulting in a range of petroleum-based materials with varying molecular weights and characteristics.

In skincare, petroleum distillates function primarily as moisturizing agents and barrier protectants. They form a thin, protective film on the skin's surface, helping to prevent transepidermal water loss and maintain skin hydration. This occlusive effect can be particularly beneficial for dry, sensitive, or compromised skin conditions.

Common types of petroleum distillates used in skincare include mineral oil, petrolatum, and paraffin. These ingredients are valued for their stability, low allergenicity, and ability to enhance the texture and spreadability of formulations. While generally considered safe for topical use, some concerns exist regarding potential contamination with polycyclic aromatic hydrocarbons (PAHs) during the refining process. High-quality, refined petroleum distillates used in cosmetics undergo rigorous purification to minimize these impurities and ensure safety for skin application.
