FIELD: personal hygiene.
SUBSTANCE: invention relates to personal hygiene. The composition for personal hygiene comprises an aqueous solution of an acidic polymer which is the copolymer of simple methyl vinyl ether and maleic anhydride in the amount of 1-3 wt. %, with some or all of the anhydride fragments being hydrolyzed to provide free carboxyl groups; non-ionogenic polymer selected from polyethylene glycols, polypropylene glycols, poloxamers, statistical copolymers of ethylene glycol and propylene glycol and their mixtures; the effective quantity of the active cation agent selected from one or more of the surface active substances on the basis of quaternary ammonium, bisguanides, cation amino acids, metal cations and their combinations; the polyamine which is lysine, in loose form or in the form of salt in a quantity of 1-5 wt. %; where the solution contains two separate aqueous phases characterized by different composition and density, where the polyamine compound interacts with the acidic polymer to form a single aqueous phase, with the non-ionogenic polymer beind separated in such a way that a second water phase is formed.

EFFECT: invention enables delivery of cation antibacterial agents in combination with anionic polymers.
