Abstract
Abstract Dentifrice formulations having improved stability against discoloration upon aging comprising an unsaturated aldehyde flavoring agent selected from the group consisting of cinnamic aldehyde and citral and about 0.1-5% of a terpene or sesquiterpene color stabilizer characterized by trisubstituted double bonds and preferably selected from the group consisting of limonene and essential oils rich in limonene such as citrus oils, ocimene, caryophyllene and clove sesquiterpenes, myrcene, terpene derivatives thereof such as citronellyl acetate, and mixtures thereof, in a dental vehicle free of oxidizing agents such as peracids and salts thereof and maintained at a pH below 8.5 and preferably acid to slightly alkaline (about 5-7.5).
