Introduction. The range of household chemicals is constantly increasing, as a result of which the population is exposed to new detergents that can directly affect the health of the population, constantly in contact with chemicals in everyday life. These circumstances require sanitary and Toxicological study of household chemicals and the development of preventive measures aimed at protecting public health. Purpose of research. To assess the risk of using synthetic detergent based on anionic and nonionic surface active substance (SAS). Material and methods. To determine the average lethal dose (LD50), a sample of detergent was injected into the stomach of 6 male rats at a dose of 5000 mg per 1 kg of body weight. Irritant effect on the skin was determined with a single application of the working solution (1.25%) to 6 rats and 3 rabbits on the trimmed side section at an exposure of 4 h, followed by flushing and into the conjunctival eye bag to 6 Guinea pigs and 3 rabbits. The follow-up period was 14 days. A single skin-resorptive effect of the working solution was studied in 20 rats of two groups of 10 animals in the control group and 10 in the experimental group. Observation period - 14 days. Multiple resorptive action was studied in 20 rats in two groups (10 animals in the control group and 10 in the experimental group) to determine the peripheral blood of animals in the control and experimental groups. The sensitizing effect of the detergent sample was studied on 20 Guinea pigs in two groups (10 in the control group and 10 in the experimental group) by a combined method. Results. LD50 orally for male rats >5000 mg/kg b.w., with a single application to the skin of rats and rabbits and the mucous membrane of the eyes of guinea pigs and rabbits does not cause irritation, does not have skin-resorbtive action (rats), does not have an allergenic effect (guinea pigs). Discussion. According to the results of studies, in accordance with the classification according to the degree of exposure to harmful substances, the tested sample according to acute oral toxicity belongs to the 4th class of danger, irritating effect on the skin and mucous membranes of the eye - 0 points; clinical signs of intoxication with a single and multiple skin-resorptive action was not revealed; sensitizing effect - 0 points. Conclusions. The studied sample of a synthetic detergent according to the parameters of acute toxicity refers to low-risk compounds (LD50 > 5000 mg/kg b.w.), does not have an irritating effect on the skin and mucous membrane of the eye, sensitizing and skin-resorptive action, which allows us to conclude that there is no risk of using the studied sample, household chemicals for the population.
