When selecting preservatives for cosmetic products a number of factors have to be considered. Legislation is an essential issue. E.g. in the EC Regulation No 1223/2009 on cosmetic products the use of certain actives is restricted for leave-on products, deodorants/anti-perspirants, products applied on mucuous membranes, oral products, products for children under 3 years of age, and aerosol dispensers (sprays).
Further parameters to consider when choosing a preservative for cosmetic products are for example quality of raw materials, formulation, pH value, type of packaging, countries where the product is to be sold, company policy – to name a few.
The large number of possible microorganisms, different packaging, storage conditions and the enormous diversity of raw materials used impose demands that cannot be met by just one active ingredient used at an acceptable dosage.
schülke has developed a wide range of multi-component preservative systems. The optimum combination of different active substances offers broad spectrum efficacy, reduces the potential of adverse toxicological findings, gives handling advantages and last but not least offers cost savings.
