A cosmetics product not made long-lasting could be used only for a few weeks because microorganisms would multiply very rapidly in the cream. This can become apparent by more skin problems and visible or smellable spoilage of the product. This is also a problem with self-made creams.
The European Cosmetics Regulation has a list of 54 substances classified as preservatives. As soon as a cosmetic product contains one of these 54 substances, the advertising statement 'Without (chemical) preservatives' may no longer be used.
On the other hand, this statement may be used as soon as the durability of a product is based on the content of other (chemical) substances which are not included as preservatives in the Cosmetics Regulations. There are several ways, as the following examples show:
High concentrations of chemical solvents like propylene glycol or butylene glycol can increase the durability of a product. With those low dosages needed as solvents, there is no objection to these substances.
Also high glycerine or alcohol concentrations (INCI: glycerine, alcohol or ethanol) have preserving properties. Their drawback is their strongly drying or irritating effect if these substances are highly dosed.
Furthermore, high perfume concentrations or irradiation or heating techniques can extend the durability of a product. The unanswered question is whether the effect is still the same, no recontamination with germs can take place after filling and the irradiation of a product will not have a harmful effect on the skin in the long term.
In this respect, the question arises whether it would not be more appropriate to preserve a product with small quantities of selected and well-tolerated preservatives, even if this means to dispense with the dubious advertising statement 'Without (chemical) preservatives'.
Belico products focus on sustainable care with maximum effect and very high tolerability. We preserve with minor quantities of selected and well tolerated substances. That is why we are happy to do without a highly questionable advertising statement.
To protect Belico preparations against germination, they are preserved with substances such as:
Moisturising active substance with anti-microbial properties.
Natural preservative, naturally occurring in blueberries and cranberries and even approved for food.
Natural preservative present in berries and bound in wine and also approved for food.
Nourishing active substance with antibacterial qualities.
