FIELD: hygiene; pharmaceutics.

SUBSTANCE: invention relates to novel aqueous compositions for oral care. Described is an oral care composition containing: a) an acidic polymer acceptable for oral use, comprising a combination of: i) copolymers with ratio of 1:4 to 4:1, maleic anhydride or maleic acid with another ethylenically unsaturated monomer capable of polymerisation, for example copolymers of methyl vinyl ether and maleic anhydride, where some or all anhydride fragments are hydrolysed to provide free carboxyl groups; and ii) copolymerized products of a mixture of acrylic acid, methacrylic acid and 2-hydroxyethyl methacrylate phosphates of formula 1, , where n equals 0, 1 or 2; b) a non-ionogenic polymer acceptable for oral use, wherein the non-ionogenic polymer acceptable for oral use is selected from polyethylene glycols, polypropylene glycols, poloxamers and mixtures thereof; c) an effective amount of a cationic active acceptable for oral use, in a free form or form acceptable for use in the oral cavity of the salt, where the cationic active agent acceptable for oral use is selected from one or more quaternary ammonium surfactants, biguanides, cationic amino acids, metal cations, their combinations; d) a stabilizing amount of the compound, which is a polyamine, in a free form or a form acceptable for use in the oral cavity of the salt, where the polyamine is lysine; e) sodium lauryl sulphate and f) water.

EFFECT: technical result is creation of new compositions for oral care and methods, which can prevent coloration and/or formation of biofilm.
