Abstract
A novel foaming agent in dentifrice compositions, e.g., tooth pastes, is proposed which is an at least partially, with a basic compound, neutralized salt of a glycerin diester compound represented by the general formula EQU R.sup.1 --CO--O--CH.sub.2 --CHOH--CH.sub.2 --O--CO--R.sup.2, in which R.sup. 1 --CO--is a residue of a monobasic carboxylic acid having 8 to 18 carbon atoms in a molecule, e.g., lauric acid, and R.sup.2 is a residue of a polybasic carboxylic acid, e.g., succinic acid, from which one of the carboxyl groups is eliminated of which is a 1% by weight aqueous solution has a pH value in the range from 4 to 10 at 25.degree. C. The dentifrice composition compounded with 0.1-10% by weight of the above defined foaming agent has outstandingly high foamability and is advantageous in respect of the little adverse influences on the stability of enzymes contained in the dentrifrices composition.
