In the formulation of cosmetic products, we can see that active substances are combined with neutral components, which do not confer preventive properties or benefits. This is the case, for example, with "C9-12 Alkane". But what is it doing there? What role does it play?

What is "C9-12 Alkane"?
The "C9-12 Alkane" is a linear and volatile organic hydrocarbon with 9 to 12 carbon atoms in their alkyl chain, whose volatility properties are similar to those of petroleum-derived isododecane and synthetic cyclomethicones.
In its raw form, the alkane C9-12 appears as a clear, colorless, and virtually odorless liquid. It is possible to produce alkanes in the C9-12 range from petrochemical raw materials or vegetable oils through a refining and fractionation process (hydrogenation).
Designed in France, the "C9-12 Alkane" used in our skincare products has a plant-based origin, derived from coconut oil .
"C9-12 Alkane": Why use it in formulations?
Hair masks, conditioners, foundations, sunscreens... the primary use of C9-12 alkane is to dissolve or dilute other ingredients in a formulation so they blend well to form a light, smooth, and fluid texture. This compound also enhances the product's spreadability and uniformity, and prevents oil-based and water-based ingredients from separating. In skincare, "C9-12 Alkane" helps to soften and smooth the skin by forming a layer on the surface due to its emollient properties, thereby giving it a feeling of freshness and suppleness.
Are there health risks associated with its topical use?
"C9-12 Alkane" is a safe ingredient and has no known side effects. It is suitable for all skin types and is non-comedogenic, meaning it does not clog pores and does not cause acne. However, it is always advisable to perform a skin test before applying it.
