In a field where safety of the products should be one of the key factors to put a formula on the market, we are assisting what experts have defined preservation crisis: a decrease of available preservative choice and a restricted number of molecules used to preserve a much bigger variety of cosmetic formulas. It is evident that ingredients as much important and fundamental as preservatives are constantly under attack, this poses serious question on the safety of finished formulas too.
The article offers interesting food for thoughts about “the perfect preservative system”: safe, effective and economically sustainable. It is possible to select a preservative solution that, at the same time, gives a broad spectrum of antimicrobial protection, does not pose any risk to the end user and is sustainable from an economic point of view.
The goal can be reached by focusing on the quality of the ingredients and on the synergistic effects between molecules, not forgetting that preservative dosage has to been evaluated according to experimental evidence of efficacy.
