A gelling composition which comprises a polymeric ingredient and a gellant for causing the polymeric ingredient to gel and which undergoes at least two kinds of gelation, i.e., relatively fast gelation F and relatively slow gelation S. The difference between the time necessary for the gelation F (Tf) and the time necessary for the gelation S (Ts) is preferably about 30 minutes or longer. Due to the constitution, a satisfactory balance between short-term adhesion and long-term adhesion can be realized.
L'invention porte sur une composition gélifiante qui comprend un ingrédient polymère et un agent gélifiant destiné à gélifier l'ingrédient polymère qui subit au moins deux types de gélification : une gélification F relativement rapide et une gélification S relativement lente. La différence entre le temps nécessaire à la gélification F (Tf) et le temps nécessaire à la gélification S (Ts) est de préférence d'environ 30 minutes ou plus. Du fait de la constitution de cette composition, il est possible d'obtenir un équilibre satisfaisant entre l'adhésion à court terme et l'adhésion à long terme.
