C13-15 Alkane

C13-15 Alkane is a hydrocarbon-derived solvent composed of branched alkane chains. It is a colourless, odourless liquid derived from mineral oil fractions and refined to cosmetic-grade purity. In skincare formulations, it functions primarily as a solvent — a substance that dissolves other ingredients and helps them remain stable and dispersed throughout the product.This ingredient is particularly valued in formulations where water-based systems would be unsuitable or where oil-soluble actives need to be incorporated. It is volatile, meaning it can evaporate from the skin's surface, leaving …

C13-15 Alkane works by dissolving oil-soluble compounds that would not dissolve in water-based systems. This keeps these actives suspended and evenly distributed throughout the formulation. When applied to skin, the alkane evaporates, depositing the dissolved ingredients on the skin's surface in a controlled, even manner.Because it is volatile, it does not remain on the skin indefinitely; this contributes to a lightweight sensory profile and reduces the risk of occlusion or buildup with regular use.

C13-15 Alkane is used in formulations by manufacturers rather than as a standalone product consumers would use directly. If you are using a product containing this ingredient, apply it as directed by the product instructions. Its volatile nature means application should be on clean, dry skin to allow even distribution and evaporation.

C13-15 Alkane is generally well-tolerated and approved for cosmetic use in the EU and other major markets. It is considered non-irritating at typical use concentrations. Those with very sensitive skin or known hydrocarbon sensitivities may wish to patch-test first.
