ORAL CARE COMPOSITIONS

摘要

The invention provides an oral care composition comprising an alkyl ester of gallic acid and a source of citrate ions; in which the amount of the source of citrate ions is at least 0.6% by weight (by total weight source of citrate ions based on the total weight of the oral care composition). The incorporation of the source of citrate ions into the composition suppresses the degradation and/or discoloration of the alkyl ester of gallic acid in the composition.
