Paraffinbase

Paraffinbase, or paraffin base, refers to a class of base formulations derived from paraffin hydrocarbons. In cosmetics and pharmaceuticals, paraffin base is a non-polar, occlusive carrier that helps reduce transepidermal water loss and provides a protective barrier on the skin. It is commonly used in ointments, salves, lip balms, and other semi-solid preparations. In candles and wax products, paraffin base denotes the paraffin wax component that forms the solid matrix of the product.

Composition and forms of paraffin base vary by application. A typical cosmetic base blends hard paraffin wax with soft paraffin (liquid paraffin or mineral oil) to achieve a semi-solid consistency. Some formulations include petrolatum (petrolatum) to increase occlusivity and reduce transepidymal water loss further. The exact ratios influence hardness, melting point, spreadability, and lubricity.

Production and sources. Paraffin hydrocarbons are produced during the refining of crude oil. The paraffin fraction is separated into waxes and liquids and refined to remove impurities such as sulfur and aromatics, yielding cosmetic-grade white waxes and oils suitable for basing formulations. The result is a stable, inert system compatible with a wide range of active ingredients.

Properties and limitations. Key characteristics are high hydrophobicity, chemical inertness, and variable melting behavior depending on formulation. Paraffin base is water-repellent and offers enduring emollience, but it is not water-soluble, which can limit certain delivery methods. It can feel waxy on the skin and may contribute to pore occlusion in sensitive individuals.

Safety and environmental notes. Paraffin base is generally regarded as safe for topical use when properly formulated, but overheating poses fire risk, and long-term occlusion can irritate sensitive skin in some people. Derived from petroleum, its use implicates considerations related to sustainability and sourcing. See also petrolatum-based bases and paraffin wax.
