Preservatives – important aids for safe cosmetics

Cosmetic products made available on the market must be safe for human health under normal or reasonably foreseeable conditions of use. This is stipulated in Article 3 of Regulation (EC) No 1223/2009 on cosmetic products, also known as the EU Cosmetics Regulation.

Official cross check or duplicate samples must also be taken and handed to the manufacturer when sampling creams.

This regulation also includes microbiological safety. Therefore, corresponding limit values are specified in DIN EN ISO 17516. To ensure the microbiological safety of cosmetics, the sufficient use of preservatives is an important element. Their use is regulated under Annex V of the EU Cosmetics Regulation.

Daily practice shows that cosmetic safety is a prevailing topic, particularly regarding impurities or incorrect labelling. Based on our experts’ many years of experience, we know that preservatives that have not been taken into account, for example from the pre-preservation of raw materials, can lead to incorrect labelling (INCI, claims).

In addition to monitoring the concentrations used, these should also be checked regularly. A preservative screening that records all preservatives present in the product (for example, phenoxyethanol, sodium benzoate, or potassium sorbate) will provide the required safety. We will be happy to conduct the relevant tests for you in our laboratories and to thereby ensure the quality and safety of your care and decorative cosmetics.
