C12-14 Isoparaffin

C12-14 Isoparaffin is a hydrocarbon solvent derived from mineral oil. It belongs to a class of ingredients called isoparaffins, which are saturated hydrocarbons with 12 to 14 carbon atoms in their molecular chain. In skincare formulations, it functions primarily as a solvent—a substance that dissolves or disperses other ingredients to create a stable, homogeneous product.This ingredient is commonly used in oils, serums, and emulsions where uniform distribution of active compounds is important. Its low volatility means it remains in the formula rather than evaporating quickly, helping to mai…

C12-14 Isoparaffin works as a solvent by using its hydrocarbon structure to dissolve lipophilic (oil-loving) compounds that would otherwise remain separate or crystallised in a formulation. This allows active ingredients to be delivered evenly across the skin's surface.Because it is a hydrocarbon, it has mild occlusive properties—meaning it can form a light barrier on the skin surface—though this effect is typically minimal compared to heavier oils. It evaporates slowly, allowing time for the product to be applied and absorbed before it disperses.

C12-14 Isoparaffin is a background ingredient in finished products, so there are no specific application instructions. Use products containing this solvent according to the manufacturer's guidance. If you have oily or acne-prone skin and prefer to minimise occlusive ingredients, check the full ingredient list to understand the overall texture profile of the product rather than focusing on this single component.

C12-14 Isoparaffin is generally well-tolerated and recognised as safe in cosmetic use. Some individuals with very oily or fungal-acne-prone skin may find products formulated with hydrocarbon solvents less suitable, as these ingredients can create an occlusive layer that may not suit their skin barrier needs.
