Analysis of parabens, thiazolinones, and other preservatives in cosmetics

The use of preservatives in cosmetic products is regulated in the positive list of the European Cosmetic Regulation EC No. 1223/2009. Only the preservatives listed there may be used for preservation purposes in the corresponding maximum quantities.

Time and again, small amounts of preservatives are detected in cosmetics, which often enter the product through pre-preserved raw materials. Even for small amounts, there is a declaration obligation in the context of the INCI list if detected in the product.

Regularly check the content of preservatives in your products as well as in the raw materials used. The BAV Institute, part of the international Tentamus laboratory group, tests for you for

• Parabens
• Phenoxyethanol
• Benzoic acid, Sorbic acid
• Thiazolinones (MIT, CIT)

In the context of a preservative screening, more than 20 substances can be detected using the latest measurement methods (HPLC/GC) in all matrices (finished product, raw materials, etc.).

Please feel free to contact us, we look forward to hearing from you.
