The present invention relates to a solid enzyme cleaning composition in which the enzyme is stable in the presence of mixtures of carbonate and bicarbonate at alkaline pH, and methods employing this composition. The enzyme cleaning composition preferably employs weight ratios of carbonate and bicarbonate to stabilize one or more enzymes in a solid, a concentrate, and/or a use composition, and at temperatures higher than ambient.
La présente invention concerne une composition solide de nettoyage aux enzymes dans laquelle l'enzyme est stable en présence de mélanges de carbonate et de bicarbonate à pH alcalin ainsi que des procédés d'utilisation de ladite composition. Cette solution de nettoyage aux enzymes utilise de préférence certains rapports en poids de carbonate et de bicarbonate pour stabiliser une ou plusieurs enzymes dans un solide, un concentré et/ou une composition et à des températures supérieures à la température ambiante.
