В статті проведено розробку основи емульсійного косметичного продукту. З використанням основних колоїдних закономірностей було визначено співвідношення поверхнево-активних речовин аніоногенної та неіоногенної природи, що стабілізували косметичну композицію, а також експериментальним шляхом визначено концентрацію фази масла. Проведені дослідження показали, що зразки основи косметичної емульсії стабільні з часом.
Ключові слова: аніоногенна поверхнево-активна речовини, неіоногенна поверхнево-активна речовина, емульсія, косметичний продукт.

Synthesis of new emulsion cosmetic products with given consumer characteristics depends on colloidal and chemical properties of both source components and finished products. In this case, particular attention is paid to the problems of the stability of cosmetic emulsions and the selection of effective emulsifier. Therefore, the development of a scientifically grounded approach to the creation of new formulations requires knowledge of the colloidal and chemical properties of both the source components and the final cosmetic emulsions. Practice shows that as stabilizers of cosmetic emulsions, surface-active substances and their mixtures are most often used to obtain ready-made compositions with given properties. At the same time, the recipes of emulsion cosmetics are based on numerous experimental data, which greatly complicates and costs cosmetic production. Establishment of the basic colloid-chemical laws of the synthesis of cosmetic emulsions and the identification of the relationship between the colloid-chemical properties of the initial components and the characteristics of the final composition. Selection of a stabilizer, consisting of a mixture of surfactants; determination of the main colloid-chemical properties of surfactants and their mixtures, as well as the behavior of individual surfactants and their mixtures at the interface between the phases of the liquid-liquid. Using the surface tension data, an oil phase is selected at the interface between oil and water phases. According to the method of weight-volume of the drop, the data of the optimal ratio of emulsion stabilizers are determined. The obtained emulsions were investigated for colloidal stability. Exhausted method for obtaining a direct emulsion stabilized by a mixture of surface-active substances. An optimal concentration of a mixture of surface-active substances has been established, which allows achieving the maximum stabilizing effect. It is determined that in order to obtain emulsions, stable for several months, the introduction of additional structural formulation, which will be the subject of our further research, is required.
Keywords: surface-active substance, adsorption equilibrium constant, emulsifier, cosmetic product, emulsion.
