Textile products are an integral part of people’s everyday life. In the process of exploitation of textile products, the human body directly contacts with textile materials throughout life, so the issue of their safety is especially important in the production of textiles and clothing. Creation of innovative formulae of washing compositions allows combining the high efficiency of the washing process with the treatment of textiles with special types of finishing. Studies aimed at the development of effective compositions with polyfunctional action based on surfactants (surface-active biodegradable substances) with the use of antimicrobial preparations are urgent and promising. They also contribute to the development of the market of chemical products, reduce the material consumption of technology and the cost of production and increase the ecological safety of the process. A complex evaluation of changes in the operational properties of textile materials after treatment with compositions of ecologically safe substances was carried out. The results of the study will contribute to reducing the ecological burden on the environment and human health. In addition, this ensures the preservation of the consumer properties of textile products during operation. The complex study of the influence of compositions of ecologically safe substances on the hygienic properties of textile products is presented. The analysis of the effectiveness of the compositions on the technological parameters (washing ability, anti-resorption capacity, composition concentration, treatment time) of the process of removal of contaminations from textile products made of cotton, polyester and their mixtures was carried out. The quantitative indices of capillarity of fabrics are determined, namely, the raising height of the composition of solutions (h, mm), which characterizes the quality of cleaning of pores of textile materials. Experimental data indicate that the treatment of fabrics made of cotton and polyester and mixtures thereof contributes to their hydrophilicity, which is expressed in improving their wettability with aqueous solutions and increasing capillarity from 131 mm to 152 mm due to the presence of adsorbed surfactants on materials. The influence of compositions of ecologically safe substances on the representative of the normal microflora of the human body P. freudenreichii was investigated. It was found that the culture was restored to 104–105 cells/ml after 48 hours of fabric sample exposure and in the P. freudenreichii sterility control environment. It was found that treatment of textile products at the concentration of compositions of ecologically safe substances of 2.5 g/l is technologically and ecologically expedient. As the high quality of cleaning of products is achieved (from 80 % to 88 %), the capillarity of textile materials increases, and the healthy microflora of human skin is preserved. The obtained research data allows us to recommend the use of compositions of ecologically safe substances for the treatment of special-purpose textile products (for military, athletes, etc.), as well as home textiles
