petrolatum

Description

Petrolatum, also known as petroleum jelly, is a semi-solid mixture of hydrocarbons derived from petroleum. This versatile ingredient has been a staple in skincare for over a century due to its exceptional occlusive properties. Petrolatum forms a protective barrier on the skin's surface, effectively reducing transepidermal water loss by up to 99%.

Its molecular structure consists of long hydrocarbon chains that create a water-repelling film, making it an excellent emollient and moisturizer. Petrolatum is non-comedogenic and hypoallergenic, making it suitable for most skin types, including sensitive and acne-prone skin. It is particularly effective in treating dry, chapped, or irritated skin conditions.

In skincare formulations, petrolatum is often used in concentrations ranging from 5% to 100%, depending on the desired effect. It can be found in various products, including lip balms, moisturizers, and ointments. Petrolatum's stability and inert nature make it an ideal base for delivering active ingredients to the skin. While some concerns have been raised about its petroleum origin, highly refined pharmaceutical-grade petrolatum is considered safe for topical use by regulatory agencies worldwide.
