SUMMARY
The stability of the antimicrobial foam cleanser for children developed in a polyethylene terephthalate container has been experimentally proven according to the following criteria: appearance, colour, odour, foam number, foam stability, pH value, the mass fraction of chlorides, microbiological purity, the mass content in the container. For a more objective and thorough analysis of behaviour of the product developed during its shelf-life, as well as for comparative estimation of the quality of its laboratory and pilot scale batches kinematic viscosity has been additionally evaluated. When developing a foam cleanser the methods for determining parameters and their characteristics (limit values) are used; they are regulated by the following normative documents – general specifications “Cosmetics for skin and hair cleaning”, specifications “Cosmetics for skin care and skin cleansers” and the research of microbiological contamination of the foam cleaning product developed. The requirements for microbiological safety of the foam cleanser gel with the complex antibacterial action have been determined according to the State Sanitary Regulations and Standards and specifications “Cosmetics for skin cleaning” developed by the scientists of NUPh. The modern formulation developed has been approved in the regional SES in Odessa and the hygienic conclusion for a new foam cleaning product for skin and hair cleaning for children has been received. The data obtained allow to set an optimum shelf-life of the product and it is 2 years at room temperature. Currently, the antimicrobial foam cleanser for children developed is produced by the pharmaceutical research centre “Beauty alliance”, Kyiv.
