Aqueous anionic maloaluminate complexes of the structure: ##STR1## at mildly alkaline pH are effective in reducing the incidence and severity of dental caries. These complexes may be advantageously incorporated in aqueous oral compositions, especially dentifrices, having pH values lying in the range of about 7.0 - 9.0.
Bathing preparations comprising a soluble aluminum carboxylate exhibit excellent dissolvability into bath water, and give a refreshing sensation to users during bathing and after bathing.
A process for the production of tris(hydroxymethyl)-aminomethan-lactate-dihydroxyaluminate by the reaction of equimolar quantities of lactic acid, tris aminomethane and aluminum isopropylate.
An effervescent tablet is produced by preparing a powdered tabletable composition containing stannous fluoride and malic acid and an alkali metal bicarbonate in a weight ratio of about 3:2 as the effervescent couple.
Improved anticariogenic oral preparations having a pH of about 2.5 to about 5.0 comprise an anticariogenically effective amount of a water-soluble aluminum salt in a surfactant-containing emulsion system suitable for use in the mouth.
An oral composition for preventing and remedying dentinal hypersensitivity which comprises containing therein aluminum and a carboxylate compound in solubilized state, with the molar ratio of the carboxylate compound to aluminum being lower than 6, and having a pH value higher than 5.
