Preservation in cosmetics:
boosting preservative performance

The challenges of preservation in cosmetics

Consumers are increasingly demanding for healthier and more sustainable products. The importance of green claims is rising, and this market trend is also affecting preservatives as core ingredients of cosmetic formulations.


Established preservatives are more and more regulated and some are increasingly under public scrutiny. The concentration levels of synthetic preservatives are reduced, and a switch to natural alternatives often means a loss of performance. Last but not least, there’s a limited choice of preservatives to obtain COSMOS or NaTrue labels.
