FIELD: medicine.
SUBSTANCE: present invention refers to cosmetology, more specifically concerns a polymeric ingredient consisting of one polymer or of a number of various polymers, and containing at least one polyurethane; said polymer or at least one of said polymers contain acid groups which are neutralised at least by 40 % at least with one inorganic base and at least by 1 % with triethanolamine. Besides, the invention refers to a cosmetic agent which contains such polymeric ingredients, and also to a method of modification of mechanical properties of the polymeric ingredient by acid group neutralisation at least by 40 % at least with one inorganic base and at least by 1 % with triethanolamine.
EFFECT: invention provides the polymeric ingredients appropriate for making cosmetic agents exhibiting good film-forming properties, and also enables adjusting their mechanical properties, particularly elasticity, and especially a hardness to elasticity relation, to the intended application.
