The definition of a cosmetic preservative
First of all, it is essential to focus on the definition of cosmetic preservative: what do we mean by that? What is a preservative?
This is actually a definition given by Regulation 1223/2009 of the European Parliament and the Council.
During a gathering focused on cosmetics, they defined preservatives as “ substances which are exclusively or mainly intended to prevent the development of microorganisms in the cosmetic product”.
The idea is therefore simple: preservatives are integral ingredients in cosmetics . They simply serve to ensure that the product does not spoil, does not expire and maintains its quality in all circumstances.
Whether it's a change in temperature or a change in humidity : thanks to preservatives, your cosmetic products remain in very good condition.
The presence of preservatives in cosmetics is therefore a legal obligation, for a fairly simple reason. There are traces of water in all cosmetics.
However, water is an ingredient that creates an environment favorable to the development of microorganisms and bacteria.
In short: without preservatives, your creams , scrubs and oils would become breeding grounds for disease. Without forgetting that their once delicate scent could change very quickly.
What is the use of a preservative in cosmetics?
The use of preservatives in cosmetics is therefore essential to prevent them from being damaged over time.
No contamination, no development of bacteria during formulation , transport, storage: the cosmetic remains in perfect condition, in all circumstances.
Good to know :
In addition to preservatives, antioxidants are often used . They ensure that the cosmetic remains in good condition, despite coming into contact with oxygen after the product has been opened.
How is the preservative chosen in a cosmetic?
Preservatives are essential ingredients in cosmetics, that’s a fact.
But who chooses which preservative will be used in this or that cream?
The choice of preservative actually depends on the formulation used for the entire product. It also depends on the galenic developed, which corresponds to the type of product.
For example, the preservative will not be the same depending on whether you have a cream, an oil or an aqueous solution.
The preservative selection criteria are also based on the cosmetic manufacturing process and the target audience. Thus, the preservative will not be the same in a baby cream and in a facial scrub for adults.
