Squalane is a lipid ingredient found in cosmetics under the INCI name Squalane. It is a saturated derivative of squalene, a naturally occurring compound. The difference in structure affects its stability, which is important when designing formulations and their storage.
Characteristics and context
In skin care, squalane is valued as an emollient, helping to achieve a soft, smooth skin feel without equating it with heavy fat. It may have different raw material origins, therefore the INCI name itself should not be automatically attributed to a plant or animal source. It is also not identical to squalene despite the similarity of names. The nature of the finished cream or serum is determined by its quantity and other ingredients, and information about its origin is confirmed by the manufacturer's specification.
Meaning and application
The saturation of the molecule distinguishes squalane from squalene and helps explain their differences in behavior. The similarity of names does not mean that they can be treated as one material. In the recipe, squalane can work with other emollients, waxes and the aqueous phase. A preparation containing this ingredient does not have to resemble another cosmetic with the same INCI name. What matters are the proportions and the whole idea of the formulation.
In practice
Source of origin requires information from the manufacturer of the raw material or product. It cannot be determined solely by the transparency of the liquid or the word Squalane in the composition. This is especially important when the user compares declarations regarding plant materials or purchasing preferences. It is also worth separating the feeling of lubrication and smoothing from the water provided by other ingredients. These functions may complement each other in care, but they are not the same technological task.
