In pharmaceutical industry, various sterilization methods are used to obtain a sterile product.
- Steam heat sterilization(Steam and dry heat)
- Sterilization by filtration
- Sterilization by irradiation ( gamma irradiator and ebeam)
- Chemical sterilization ( Eto gas and formaldehyde)
- Sterilization by Irradiation Method: It is one of the alternative sterilization methods, which is very practical and becoming widespread. Gamma rays are of high energy photons. They remove an electron when they interact with substance and cause ionization. Drug manufacturers should take into consideration that free radicals forming as a result of such reactions may affect pharmaceuticals and package materials and should conduct physical, chemical and biological tests on the drug and package materials after irradiation.
STERILIZATION OF COSMETIC PRODUCTS
In terms of reproduction factors such as humidity, medium acidity and appropriate minerals, Cosmetic product formulations used in cosmetic industry are quite convenient media for the micro organisms to live and reproduce. Moreover, such substances as carbohydrates, proteins, amino acids, vitamins, steroids, peptides, fatty acids, sugar and fat alcohols are the substantial food sources which support the reproduction of micro organisms. When these factors are evaluated, the risk of micro organism contamination in cosmetic products is high and the presence of this risk affects human health significantly.
Gamma irradiation is a method used in cosmetic products to reduce the number of micro organisms. By means of this method, micro organism contamination is lowered below the specified levels.
