Abstract
Foamable dental fluoride compositions containing a water-soluble fluoride component in an amount sufficient to provide from about 0.5 to about 10% by weight available fluoride are disclosed. The compositions include an oil in water emulsion which is preferably dispensed in combination with an aerosol propellant to provide microcell-stable foam which exhibits enhanced foam retention properties. Methods of treating teeth with fluoride and methods of preparing the foam are also disclosed.
Claims26
A foamable dental fluoride composition for forming dental foams comprising
- (a) from about 0.5 to about 10 percent by weight available dental fluoride;
- (b) from about 1.0 to about 10 percent by weight of an emulsifier, said emulsifier selected from the group consisting of cetyl phosphate and stearic acid, indeceth carboxylic acid, acid forms of ethoxylated fatty alcohols, oleth 3, oleth 5, oleth 10, oleth 20, steareth-10, celeth-20, and mixtures thereof;
- (c) from about 0.5 to about 5 percent by weight of an emulsion stabilizer, said emulsion stabilizer being selected from the group consisting of oleth-3-phosphate, oleth-10 phosphate, cetyl phosphate, PPG-10 cetyl ether phosphate, cetostearyl alcohol, stearyl alcohol, olelyl alcohol and related fatty alcohols with linear carbon chains and wax-like materials having high molecular weights, behenic acid and mixtures thereof;
- (d) from about 0.5 to about 3.0 percent by weight of a anionic or nonionic surfactant which contributes to the emulsification of the emulsifier and emulsion stabilizer in the dental foam;
- and
- (e) from about 1.0% to about 10.0% by weight of polyethylene glycol (PEG).
