Abstract
An adhesive cosmetic strip is provided which includes a flexible water-insoluble substrate, an adhesive composition deposited onto the substrate and an agent interactive with water present in a sufficient quantity to induce a change of temperature of the strip. When applied to the skin, the strip is warmed 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.
Claims13
An adhesive cosmetic strip for placement on skin comprising:
- (i) a flexible water-insoluble substrate;
- (ii) an adhesive composition deposited onto the substrate;
- and
- (iii) an agent interactive with water present in the adhesive composition in an amount from at least about 40% by weight of the adhesive composition and in a sufficient quantity to induce a change of temperature in the strip of at least about 2° C., the adhesive composition allowing the substrate to adhere to skin.
A method for cooling skin comprising applying to the skin an adhesive cosmetic strip for placement on skin comprising:
- (i) a flexible water-insoluble substrate;
- (ii) an adhesive composition deposited onto the substrate;
- and
- (iii) an agent interactive with water present in the adhesive composition in an amount from about 1 to about 80% by weight of the adhesive composition and in a sufficient quantity to induce a reduction in temperature in the strip of at least about 2° C., the adhesive composition allowing the substrate to adhere to skin.
