The potential dermo-irritative properties of bicomponent polymer systems based on a hydrophilized unsaturated polyester resin were clinically and experimentally investigated. For that purpose, forecasting tests for both irritation and allergization effect of cosmetic products and raw materials on volunteers' skin were used. Polymer compositions possessing a definite complex of properties such as low toxicity, small relative mass and high-strength parameters in combination with good appearance were considered appropriate. To this end, polymer composites which had already demonstrated in previous investigations a low toxicity after peroral and intraperitoneal introduction in animals and possessed appropriate deformation-strength behaviour as established in the present paper were selected. The analyzed polymer systems did not demonstrate any potential irritative and human-skin contactsensibilizing properties at all.
