Patent

CA 2391936

The present invention provides an adhesive cosmetic strip which comprises a flexible water-insoluble substrate, an adhesive composition deposited onto the substrate and a sufficient quantity of an agent which is capable of interacting with water to induce a change in the temperature of the strip. When applied to the skin, the temperature of the strip is changed by a reaction between water and an exothermic or endothermic agent held within the strip.Moisture within the skin or externally applied water penetrates the strip and will react with the agent to cause an increase or decrease in temperature.

L'invention concerne un timbre cosmétique adhésif comprenant un substrat souple, insoluble dans l'eau, une composition adhésive déposée sur ce substrat, ainsi qu'une quantité suffisante d'un agent capable d'interagir avec l'eau pour induire un changement dans la température du timbre. Lorsque l'on applique le timbre sur la peau, la température de celui-ci change, par suite d'une réaction entre l'eau et un agent exothermique ou endothermique contenu dans le timbre. La vapeur d'eau contenue dans la peau, ou l'eau appliquée de manière extérieure, pénètre dans le timbre et réagit avec l'agent, cette réaction provoquant une augmentation ou une diminution de la température du timbre.
