Abstract

Clay gained great popularity after the discovery of its ability to restore tissues, absorb salts, toxins, gases, unpleasant odors, etc. To reveal antitoxic, antiseptic, bactericidal, conservation properties. The chemical and mineral composition and unique properties of clay make it an attractive raw material in a number of fields, including cosmetology. Objectives: Unexplored clays of different regions obtained in the territory of Georgia - blue clay - Lentekhi district, Chukuli village, Fishkhori river bank and red clay - Ozurgeti district, Gomi mountain should be conducted. Methods: Properties and composition of samples are determined by physical and chemical methods of research: gravimetric, photometric, volumetric and atomicabsorption methods. Results: A comparative study of the granulometric composition of particles, elemental composition, sorption properties, competition coefficient and colloidity was established. From the examined clays, the red clay of Gomi Mountain was chosen and based on it, the base hydrogel recipe was created. Some of their physicochemical properties have been studied: colloidability, thermostability, organoleptic parameters, pH has been determined and rheological research has been carried out. The percentage of red clay fraction (particle size < 0.16 mm) of Gomi mountain is almost 2.5 times higher than the same fraction of blue clay of Lentekhi region.The red clay of Gomi mountain is a good adsorbent with its physico-chemical properties, it is characterized by a high absorption coefficient and the ability to create hydrogels. It can be used in cosmetics both in its native, powdery form and in the form of hydrogel of various concentrations. Lentekhi blue clay contains up to 50% silt, so its use in cosmetics is complicated. Conclusion and Recommendation: Based on the obtained base hydrogel, a lotion recipe for the care of oily and problematic skin has been developed.
