Formulations for oral care and dental care, which contain tin (II) salts and water, are stabilized against hydrolysis of the tin salts by the addition of certain cationic surfactant diamine salts. The additive fully preserves, or even potentiates, the inhibiting action of tin salts on plaque formation an dental caries. The formulations advantageously also contain a non-ionic, water-soluble addition product of ethylene oxide which further improves the stability.

Process for stabilizing aqueous compositions containing tin salts

An oral composition for the care of the mouth and teeth which contains as an active ingredient, a compound of the formula: ##STR1## in which R.sup.1 and R.sup.2 in formulas I and II, may be the same or different and are selected from the group consisting of methyl, ethyl, chloroethyl, hydroxyethyl, aminoethyl, carbethoxymethyl, n-propyl, isopropyl, n-butyl, isobutyl, 1-methylpropyl, t-butyl, hexyl, cyclohexyl, methylcyclohexyl, benzyl, phenyl, chlorophenyl, methoxyphenyl, chloronitrophenyl or dimethylnitrophenyl.

Novel oral compositions for the care of the mouth and teeth

An oral composition for the care of the mouth and teeth which contains as an active ingredient, a compound of the formula: ##STR1## wherein R.sup.1 and R.sup.2, which may be the same or different, are hydrogen atoms, alkyl groups having 1 to 8 carbon atoms, cycloalkyl radicals, aralkyl radicals or aromatic or heterocyclic groups, whereby both R.sup.1 and R.sup.2 can be substituted. The compositions of the present invention inhibit plaque formation, paradentosis and to some extent caries.

Novel oral composition for the care of the mouth and teeth

Oral compositions for plaque and caries inhibition contain a salt of an oxo-acid (formerly called oxy-acid) of phosphorus or a mixed salt of an oxo-acid of phosphorus and hydrofluoric acid with an organic base.
