Ceresin

Description

Ceresin is a refined mineral wax derived from ozokerite, a naturally occurring fossil wax. This white to pale yellow, odorless substance has a low melting point and exhibits excellent stability and water-repellent properties. In skincare formulations, ceresin functions as an emollient, thickener, and stabilizer, contributing to the texture and consistency of various products.

The molecular structure of ceresin consists primarily of long-chain hydrocarbons, which form a protective barrier on the skin's surface. This barrier helps to reduce transepidermal water loss, thereby improving skin hydration and softness. Ceresin's occlusive nature makes it particularly beneficial in lip balms, moisturizers, and protective ointments.

Ceresin is valued for its compatibility with a wide range of cosmetic ingredients and its resistance to oxidation, ensuring product stability and longevity. It is often used as an alternative to beeswax or paraffin in formulations where a vegan or petroleum-free option is desired. While generally considered safe for topical use, it is non-comedogenic and unlikely to clog pores. However, as with any ingredient, patch testing is recommended for individuals with sensitive skin or known allergies to ensure compatibility.
