Polyethylenimine mono-and difluorophosphates are obtained by the reaction of solutions of polyethylenimines with monofluorophosphoric acid or difluorophosphoric acid at low temperatures. The novel polyethylenimine salts have demonstrated valuable properties in the prevention of dental caries.

Anticaries agents

Novel alkylamine fluorophosphates of the formula: ##STR1## wherein R is a linear or branched alkyl group containing 1-20 carbon atoms; R.sub.1 is lower alkyl or hydrogen, R.sub.2 is alkyl or hydrogen; X is 1 or 2; Y is 1 when X=1; Y is 1 or 2 when X=2; m and n are positive whole integers whose sum is 3. When R, R.sub.1 and R.sub.2 are alkyl they can be substituted with an hydroxy group. The novel fluorophosphates have been found to be effective in reducing the acid solubility of tooth enamel.
