Chlorinated Paraffin

Chlorinated paraffin is a synthetic hydrocarbon derived from mineral oil that has been chemically treated with chlorine. It functions primarily as a skin conditioning and protective agent in cosmetic formulations, helping to maintain moisture and create a protective barrier on the skin's surface.In skincare products, it serves multiple roles: it conditions the skin, provides a protective film, acts as a solvent to help dissolve other ingredients, and adjusts the thickness and flow of formulations. It is a common ingredient found across a range of skincare products, from lightweight serums t…

Chlorinated paraffin works by depositing a thin, occlusive film on the skin's surface. This film helps to trap moisture within the skin and protect against external irritants, much like other occlusive ingredients. The synthetic nature of the ingredient means it doesn't penetrate deeply; instead, it remains on the outer layers where it can condition and protect.Its ability to control viscosity also makes it useful in formulation — it helps adjust the thickness of products so they spread evenly and feel pleasant on application.

Chlorinated paraffin is typically used as a background ingredient in formulations rather than an active treatment. It works best when applied to clean, slightly damp skin to help seal in hydration. Because it creates an occlusive film, it may feel heavy on very oily skin or in warm climates; in these cases, use sparingly or reserve for evening application or drier areas only.

Chlorinated paraffin is generally well-tolerated in cosmetic concentrations and is approved for use in skincare products across major regulatory bodies. It is not known to be a common irritant or allergen, though individual sensitivity is always possible.
