Effervescent dual component toothpaste composition comprising an alkali metal bicarbonate, an acid and alkyl vanillyamide (capsaicin

摘要

A two component effervescent dentifrice composition comprises a first alkali metal bicarbonate containing dentifrice component and a second acid containing dentifrice component; the first and second component are separated prior to use wherein the effervescent signal generated upon the combination and mixing of the components is enhanced by the presence in the combined components of a naturally occurring alkyl vanillyamide. The presence of the alkyl vanillyamide provides a unique and consumer measurable sensation during brushing instilling in the consumer a perception of enhanced product cleaning performance. Preferably the alkyl vanillyamide is capsaicin, alkali metal bicarbonate is sodium bicarbonate and the second acid-containing dentifrice component contains phosphoric acid. Also described is a method for enhancing sensory signal from an effervescent dentifrice.
