Patent

CA 2247986

There is provided a composition comprising an admixture of a finely divided alginate (or a salt or derivative thereof) together with a finely divided carrier material. The composition overcomes the problems associated with applying gel-forming alginates to a body surface without formation of a clumpy paste that leads to local irritation. An admixture of sodium alginate and a water-soluble glass carrier material is preferred. Optionally, the alginate and carrier material each have a particle size of less than 150 µm diameter and are present in a weight ratio of 20:80 to 80:20. The presence of the carrier aids even gel formation and also promotes wound healing.

L'invention porte sur une composition consistant en un mélange additionnel d'un alginate finement divisé (ou leurs sels ou dérivés) et d'un support également finement divisé. Cette composition résout les problèmes liés à l'application d'alginates en gélifiants sur des surfaces corporelles en empêchant la formation d'une pâte compacte occasionnant des irritations locales. Un mélange d'alginate de sodium et d'un support de verre hydrosoluble a la préférence. Eventuellement, alginate et son support peuvent présenter une taille de particules de moins de 150 ?m de diamètre et être présents selon un rapport allant de 20:80 à 80:20. La présence du support contribue à la gélification et favorise la cicatrisation des plaies.
