The topic of preservation is always of importance to formulators and finished good marketers. Formulators are aware of the necessity to adequately preserve their products in order to ensure product safety and be in compliance with the respective legislations. This task is much more difficult when marketing requirements are added to factors influencing the preservative choice. Demands such as global approval, soft preservation, „free of“ …, etc. have limited the number of acceptable actives.
Increasing marketing pressure has resulted in an interest in reducing the amount of traditional preservatives in cosmetic formulations or in finding novel ways to keep cosmetic products microbiologically stable. It is now more important than ever that preservation or microbiological stability is an integral part of new formulation concepts. At an early stage of product development, formulators must consider all possible methods of enhancing the efficacy of traditional preservative actives, e.g. using chelating agents or multifunctional materials. There are some ingredients known in the market which can boost the efficacy of preservative actives without having an own antimicrobial effect.
