Use of healing mud when making a fermented cosmetic mask

The current concern in the cosmetic industry is preparing of cosmetics products from aggressive preservatives-free natural, environmentally friendly ingredients, which would protect skin from external disturbance. The purpose of our work is to develop a biotechnological method for obtaining a cosmetic mask based on fermented curd whey in the presence of therapeutic mud. We used standard methods for determining microbiological and physicochemical parameters. The optimal concentration of therapeutic mud for fermentation was determined by quantitative estimation method of cells in the HMS nutrient medium after fermentation in pasteurized curd whey with the addition of different amounts of therapeutic mud. The result of the study is development of a cosmetic mask based on fermented whey mixture adding 10% of therapeutic mud of nutrient medium volume. The addition of therapeutic mud in an amount of 10% of nutrient medium volume contributed to increase of biomass of propionic acid bacteria up to 82×108 units and to the regulation of the pH of medium. Control of the finished mixture for microbiological, physical-chemical, organoleptic indicators showed the absence of pathogenic microflora and the content of propionic acid bacteria 1·108 units. The results of the study allow to characterize the ready mix as a product that combines biologically active substances, microelements, therapeutic mud hormones and metabolites of propionic acid bacteria, which can form the basis for the preparation of any cosmetics. The paper also proposes a method for preparing a cosmetic mask from fermented curd whey with propionic acid bacteria in the presence of therapeutic mud and a recipe for their manufacture with the addition of bentonite clay to stabilize the system. Prototypes of the obtained mask show skin elasticity and complexion improvement and smoothing of fine wrinkles.
