Total Claims: 11
Claim 1
Independent Claim
122 words
An oral paste composition, comprising: 0.01 to 5% by weight of an antiplasmin agent selected from the group consisting of tranexamic acid, ε-aminocaproic acid and their alkyl ester and aryl ester derivatives, 0.01 to 10% by weight of a flavor mixture, a surface-active agent and water characterized in that said flavor mixture comprises 0.05 to 90% by weight based on the total weight of the flavor mixture of a compatible aldehyde flavor selected from the group consisting of perillaldehyde, myrtenal, benzaldehyde, anisaldehyde, heliotropin, 3-methylbutanal, 2-methylbutanal, hexanal, 10-undecanal, decanal, citronellal, dodecanal, hydroxycitronellal, α-methylcinnamaldehyde and mixtures thereof wherein said oral paste composition is free of Schiff base discoloration caused by an antiplasmin agent amino group reacting with an aldehyde group of said aldehyde flavors.
