The paper presents the results of the study of the effects of conditioning agents on the basis of polyorganosiloxanes-cyclopentasiloxane, dimethicone, SilCare Silicone SEA, and their alternative substitute on the basis of coco caprylate Cetiol C5 on the rheological and organoleptic properties of the modeled cosmetic emulsion system. The influence of cosmetic emulsion on the basis of investigated compounds on the water-fat balance of the skin is determined. It has been established that in order to create a quality emulsion cosmetic product it is necessary to use conditioning agents on the basis of polyorganosiloxanes.

The study of the influence of physicochemical parameters of different sorts of soybean on the extraction of oil in soybean processing, as were as determining the quality of soybean products – petal, meal and oil. Soybean seed samples of three sorts were selected for the study: Mriya, Skelya and Ukrainka, of different humidity and degree of contamination. The Perten DA 7250 infrared analyzer and physicochemical methods in accordance with DSTU were used to determine the quality indicators of soybean seeds. Skelya sort was noted as more oily (20.36%), and Ukrainka sort as more protein (38.49%), the mass fraction of fiber in the samples is from 5.9 to 6.5%. The scheme of soybean processing by the method of forcing – extraction with hexane at the enterprise of «Tavria Agroinvest» was used. Soybean oil is extracted according to the technological regime of the enterprise. After the process of extraction and distillation of the solvent in the evaporator tank, unrefined soybean oil and soybean meal are obtained. According to the scheme of the extraction process, the quality of the final product will depend on the degree of grinding of raw materials and the quality of the petal. Organoleptic and physicochemical parameters of unrefined soybean oil and soybean meal obtained at «Tavria Agroinvest» from three sorts of soybean seeds were determined. It is shown that from moist materials (18.5%) is obtained oil with higher acid and peroxide numbers. The iodine number and cloud point of soybean oil of this sample are also higher than those obtained for dry seeds. The quality indicators of soybean meal for the studied soybean seed sorts were obtained. Mass fraction of crude protein in terms of absolute dry matter is the largest for the Skelya sort and is 46.2%. Soybean meal sort Mriya is less purified from moisture and crude fat, and its high acid number can shorten the shelf life.

Based on theoretical studies, the authors of this paper propose the use of cosmetic organosilicon polymers (commonly called silicones) for the extraction of a complex of biologically active substances contained in vegetable raw materials. It is important to note that the biological molecules do not interact with the organosilicones and, therefore, their properties are not altered after the extraction. In this work, we investigate the efficiency of several polyorganosiloxanes as extractants of vegetable raw materials (Calendula Officialis L. and Artemisia Absinthium L.) useful for the preparation of cosmetic emulsions. Specifically, the extraction studies were conducted by using polyorganosiloxanes with a single component (polydimethylsiloxane Silicone Oil 350 cSt, cyclopentasiloxane BRB CM 50, and phenyltrimethicone BRB PTM 20) as well as a mixture (PEG-12 polydimethylsiloxane BRB 526, a solution of dimethiconol in cyclopentasiloxane BRB 1834, and amodimethicone BRB 1288). Compared to water and ethyl alcohol, polyorganosiloxanes are more effective in the extraction of the biologically active substances that are contained in the raw plants. Interestingly, the combination of different polyorganosiloxanes improved the extraction efficiency. The attained knowledge can be helpful in the development of a novel protocol for the formulation of emulsions appealing for cosmetic applications.

Abstract. In this paper, the effect of cationic polymers on resistance of oleophobic finishing to washing and organic solvents action is investigated. It was established that the use of cationic polymer CP.2 increases resistance of the obtained protective finishing to 3-4 cycles of soap and soda treatments and significantly increases the resistance of oleophobic effect to the action of organic solvents.
