Skin irritation, such as diaper rash, appearing when the skin is allowed to remain in contact with proteolytic enzymes found in feces is prevented by inactivating the fecal proteolytic enzymes by contact with organophilic clays. The organophilic clays are applied to the skin in areas likely to come into contact with feces or to garments such as diapers. A composition suitable for practicing the method of the invention comprises an amount of an organophilic clay effective to inactivate irritating fecal proteolytic enzymes dispersed in a pharmaceutically acceptable non-toxic dermatological vehicle. A fabric incorporating organophilic clay, preferably dispersed in a matrix of a superabsorbent polymer, is useful for preparing diapers for infants that can help to prevent skin irritation by fecal enzymes.

La présente invention concerne la prévention de l'irritation de la peau telle que l'érythème fessier du nourrisson qui se produit lorsque la peau doit rester en contact avec les enzymes protéolytiques des matières fécales. Le procédé consiste à inactiver ces enzymes protéolytiques par une mise en contact avec des argiles organophiliques. On applique ces argiles organophiliques sur des zones de la peau susceptibles d'entrer en contact avec les matières fécales ou sur des vêtements tels que des couches de bébés. L'invention concerne également une composition convenant particulièrement à la mise en oeuvre du procédé de l'invention. Cette composition, qui renferme une quantité d'une argile organophilique suffisante pour inactiver les enzymes protéolytiques, est dispersée dans un excipient dermatologique non toxique admis en pharmacie. L'invention concerne enfin un produit textile incorporant de l'argile organophilique dispersée de préférence dans une matrice d'un polymère superabsorbant, ce qui fait que ce produit textile convient particulièrement à la confection de couches pour bébés susceptibles de prévenir l'irritation de la peau par des enzymes fécales.
