Summary

In this study, we aimed to use gamma irradiation for decontamination of cosmetic products in order to achieve the acceptable microbiological limits. Cosmetic products and raw materials were irradiated (5-7.5-10 kGy) and physicochemical, microbiological and biological properties of these samples were evaluated in normal and stress storage conditions. It was found that the physicochemical properties of samples tested were changed after irradiation. No change was observed in skin irritation properties of all samples tested. Decontamination dose for all samples, excluding starch, was found to be about 5 kGy or below.

Key Words :
Decontamination by gamma radiation, cosmetic products, cosmetic raw materials.
