Oral care hydrates help to mix and manage incompatible ingredients, for example, by adding a polyamine stabilizer, combined with an anti-corrosion and stain resistant polymer, effectively providing an antibacterial toxin toxin. Like lysine 2. Design and use method. Claim 18: the composition of any of the above requirements,Characteristics: (a) orally acceptable acid polymers include (a) 0.5% to 1.5% impurities and methyl vinyl copolymers and (b) 0.5% to 1.5% phosphate / acrylic copolymers；(b) Orally acceptable nonionic polymers include a polyol with a molecular weight of between KWD 5 and KWD 20, a content of between 0% and 3%, and a 407 polox of between 0% and 1%.(a) At a combined rate of 1% to 3%；(c) There is an effective amount of orally acceptable ionic activators, such as free-form or orally acceptable salts, which contain 0.1% to 0.2% oxides of chloride；(d) As a free-form or orally acceptable salt, the polyamine compound is lysine, which is a free-form or orally acceptable salt with the content between 0.5% and 3%；(e) The amount of water is 70% - 95%；Alternative ingredients also include not more than 1% sodium sulfate；All of these quantities are represented by the total weight of the components.Composiciones acuosas de cuidado oral que son útiles para combinar y administrar ingredientes poco compatibles, por ejemplo, para proveer niveles eficaces de agentes antibacterianos catiónicos en combinación con polímeros que protegen contra la erosión y las manchas, mediante la adición de una cantidad estabilizadora de una poliamina, por ejemplo, lisina. Métodos para elaborarlas y usarlas. Reivindicación 18: La composición de cualquiera de las reivindicaciones precedentes, caracterizada porque: (a) el polímero ácido oralmente aceptable comprende una mezcla de (a) un copolímero de anhídrido maleico y éter metilvinílico en una cantidad de entre 0,5% y 1,5% y (b) un copolímero fosfato / acrilato en una cantidad de entre 0,5% y 1,5%； (b) el polímero no iónico oralmente ace
