CA 2500373

Liquid dentifrice compositions are provided which give improved cleaning performance and flavour display when used in the small amounts that can be dispensed onto a typical electric toothbrush head. The liquid dentifrice has a viscosity of less than about 500 Pa.s at 0.1 s-1 at 25~C. Representative compositions include greater than about 2 % by weight of a surfactant; greater than about 1. 2 % flavour and greater than 50 % liquid carrier materials, including controlled amounts of water and humectants, or alternatively polyoxyethylene thickeners.

L'invention concerne des compositions de dentifrice apportant une performance de nettoyage et une présentation de goût améliorées lorsqu'elles sont utilisées dans les faibles quantités qu'il est possible de distribuer sur une tête de brosse à dents électrique classique. Le dentifrice liquide possède une viscosité inférieure à environ 500 Pa.s à 0.1 s-1 à 25 ·C. Des compositions représentatives contiennent un peu plus de 2 % environ en poids d'un tensioactif, environ un peu plus de 1, 2 % d'arôme et un peu plus de 50 % de matériaux support liquides, y compris des quantités mesurées d'eau et d'humectants, ou, dans un autre mode de réalisation, d'épaississants à base de polyoxyéthylène.
