Vitamin E: Can we classify it as a preservative?

According to the European Regulation n°1223/2009 of the European Parliament and Council pertaining to cosmetic products, a preservative is defined as "a substance exclusively or primarily intended to inhibit the growth of microorganisms in the cosmetic product". From this definition, it is understood that a preservative must possess a certain antimicrobial activity. The preservatives authorized in cosmetic care are all listed in Annex V of this regulation, also specifying in which type of product they can be incorporated and in what quantity.

Indeed, most cosmetic formulations, due to their high water content, are products that can easily be degraded by microorganisms. Microbial contamination of cosmetics represents a significant risk to consumer health as it can lead to irritations, inflammations or allergies, particularly when they are applied to damaged skin, around the eyes or on the skin of babies. Hence the essential role that preservatives play. However, it should be noted that not all preservatives are equal and some may pose a risk to human health or the environment. That's why Typology has decided to exclude certain ones, as a precautionary principle, such as methylisothiazolinone and phenoxyethanol.

Note : Consumers also play a role in the proper preservation of their cosmetic product. Adhering to expiration dates, periods after opening, storing products in a cool, dry place away from light, and regularly checking their organoleptic properties (color, texture, smell...) are key behaviors to adopt.
