Abstract

An environmentally friendly, granular, phosphate-free dishwashing agent for automatic dishwashers is proposed with alkali metal gluconate as phosphate substitute. It contains: 10 - 70% by weight of water-soluble alkali metal silicate with a ratio of silicon dioxide to alkali metal oxide greater than 1:1; 0 - 50% by weight of alkali metal carbonate; 2 - 15% by weight of polymeric sequestrants or dispersants, preferably of the polycarboxylate type, especially homopolymers of acrylic acid or copolymers with other organic acids or ethers which contain vinyl groups, especially maleic acid; 3 - 15% by weight of alkali metal salts of acids obtained from sugars by fermentation, especially of Glu acid or lactobionic acid; 2 - 15% by weight of an oxygen-based bleach from the group of peroxo compounds or peroxohydrates or mixtures thereof, which liberate hydrogen peroxide in water; 0 - 15% by weight of a bleach activator from the group of compounds which liberate reactive peracids, especially peracetic acid, on exposure to hydrogen peroxide; 0 - 2% by weight of an alkali metal salt of a phosphonic acid to stabilise the bleach during storage; 0 - 5% by weight of enzymes or enzyme mixtures from the group of hydrolases, especially proteases, amylases and lipases; 0.5 - 5% by weight of a low-foam nonionic surfactant. d
