6. The article according to claim 1 , wherein the support comprises at least two sheets, at least one of which comprises a fiber soluble in water at a temperature of 0-30° C.
7. The article according to claim 1 , wherein
the support comprises at least two sheets having a cavity between the at least two sheets, with at least one of the sheets comprising a fiber soluble in water at a temperature of 0-30° C.,
and
the cavity contains the composition comprising at least one compound which causes a temperature change due to an exothermic or endothermic reaction when contacted with water.
8. The article according to claim 7 , wherein the at least two sheets having a cavity are nonwovens.
9. The article according to claim 8 , wherein
one of the at least two sheets is a nonwoven, consisting of fibers soluble in water at a temperature of 0-30° C., and
the other of the at least two sheets is a nonwoven, consisting of water-insoluble fibers.

an amount of the at least one compound which causes a temperature change due to an exothermic or endothermic reaction when contacted with water ranges from 10 to 100 wt. % relative to the total weight of the composition.
14. The article according to claim 1 , wherein the at least one compound which causes a temperature change due to an exothermic or endothermic reaction when contacted with water is at least one exothermic compound selected from zeolites, exothermic inorganic salts, polyols having at least 2 hydroxyl groups and at least 3 carbon atoms, ethers of vanillyl alcohol, gingerol, capsaicin, eugenol, cinnamon oil, benzyl alcohol, and mixtures thereof.
15. The article according to claim 1 , wherein the at least one compound which causes a temperature change due to an exothermic or endothermic reaction when contacted with water is at least one endothermic compound selected from endothermic inorganic salts, mint, urea, and mixtures thereof.
16. The article according to claim 1 , wherein the at least one compound which causes a temperature change due to an exothermic or endothermic reaction when contacted with water or the composition containing the compound is a powder or paste.
17. The article according to claim 1 , wherein an amount of the composition carried by the support is between 10 and 1000 wt. % relative to the weight of the support.
18. The article according to claim 1 , wherein the composition carried by the support further comprises at least one compound selected from mousse-forming surfactants, water-soluble polymers, fats, oils, exfoliating agents, keratolytic agents, moisturizers, soothing agents, antimicrobials, and a mixture thereof.
19. The article according to claim 1 , wherein the article is a skin cleansing or make-up removal product, an exfoliator, a skin care product, a rinsing patch, a hair care product, or a make-up product.
20. The article according to claim 1 , wherein the support is one selected from the group consisting of a pad, a mask, a patch, a mobcap, a finger of a glove, a glove, a sheet for cutting out, a wipe, a disc, an oval and a rectangle.
