Methods and formulations for enhancing the dissolution of a solid material in an aqueous solution incorporate an effervescent system into the material. Effervescent systems include (i) the combination of one or more enzymes and one or more substrates for said enzymes and (ii) a metal ion catalyst and a substrate for that metal ion catalyst. The combination of either (i) the enzyme and the substrate or (i) metal ion catalyst and substrate is capable of producing a gas when the material is in an aqueous solution. The effervescent system is particularly suited for incorporation into laundry detergents, dishwashing detergents, antacids, vitamins, contact lens cleaners, denture cleaners and other household products. It is believed that the gas produced by the interaction of the enzyme or metal ion catalyst and the approproate substrate enhances and facilitates dissolution of the material by increasing the surface area of the material that is in contact with the aqueous medium.

Procédés et formulations servant à amplifier la dissolution d'un matériau solide dans une solution aqueuse et consistant à introduire une substance effervescente dans ce matériau. Les systèmes effervescents sont composés (i) de la combinaison d'un ou de plusieurs enzymes et d'un ou de plusieurs substrats desdits enzymes et (ii) d'un catalyseur d'ion métal, ainsi que d'un substrat de ce catalyseur. La combinaison soit (i) de l'enzyme et du substrat, soit? ¿(i) du catalyseur d'ion métal et du substrat est capable de produire un gaz quand le matériau se trouve dans une solution aqueuse. Ce système effervescent est particulièrement conçu pour être incorporé dans des détergents de lavage de linge, des détergents de lavage de vaisselle, des antacides, des vitamines, des agents nettoyants de lentilles de contact, des agents d'hygiène buccale et d'autres produits ménagers. On pense que le gaz produit sous l'effet de l'interaction de l'enzyme ou du catalyseur d'ion métal et du substrat approprié amplifie et favorise la dissolution du matériau par augmentation de la surface dudit matériau, qui se trouve en contact avec le milieu aqueux.
