title: Gamma irradiation, rheological and microbiological analysis of cosmetic products.
abstract: 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.
