Selection of Preservatives

When selecting preservatives for wet tissues a number of factors have to be considered.
Legislation is an essential issue. Cosmetic wipes marketed in the European Union have to be in compliance with the Cosmetics Directive and the Cosmetic Products Regulation. Wet tissues claimed to cleanse hard surfaces have to be preserved according to the Biocidal Product Directive (BPD). The scope of the BPD is very wide and covers disinfectants for home and industrial use as well as preservatives for manufactured and natural products.


Further parameters to consider when choosing a preservative for wet tissues are for example quality of raw materials and substrate, formulation of the wet tissue liquid, 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.
