Gamma irradiation, rheological and microbiological analysis of cosmetic products.
In this study, we aimed to use gamma irradiation for decontamination of cosmetic product (gel) achieve the acceptable microbiological limits. Cosmetic product vials were irradiated (10-100 kGy) and physicochemical, microbiological and biological properties of these samples were evaluated in normal conditions. Decontamination dose for all samples was found to be about 10 kGy or below. A pseudoplastic feature was induced in the gel after irradiation suggesting a large applicability of gamma radiation to this purpose.
