Definitions
- the invention relates to a new use of the lipases known per se in the context of low-alkaline agents for the automatic washing of dishes and as a means for supporting the bending systems for removing tea stains.
- Bleachable soiling is generally the case when washing dishes by machine at today's cleaning temperatures of approx. 55 ° to 65 ° C. easily removed. In the course of saving energy, dishwasher manufacturers are now starting to offer low-temperature cleaning programs with temperatures of around 40 ° C.
- Eliminate bleachable stains such as tea stains / tea deposits, coffee residues, dyes from vegetables, lipstick residues and the like.
- lipolytic enzymes in automatic dishwashing detergents is known per se. Those skilled in the art know that they are helpful in cleaving triglycerides and fatty ester contaminants.
- EP-B-271 155 teaches the use of lipases in dishwashing detergents and in rinse aids. It is stated there that the formation of films and stains is significantly reduced. The reduction in film formation here means the reduction in greasy films, not the reduction in tea deposits.
- European patent application 346 136 describes the reduction of stains and film formation by a special, genetically modified lipase.
- the present invention therefore relates to the use of esterases, preferably lipases, in or together with lower alkaline agents for automatic dishwashing, containing 15 to 70% by weight of a builder component, 0.5 to 20% by weight of an oxygen-based bleaching agent and, if desired Bleach activators, surfactants, corrosion inhibitors, hydrotropic substances, foam inhibitors and other components customary in machine dishwashing detergents, characterized in that 0.001 to 1.5% by weight of lipase, if desired in combination with 1 to 25% by weight of multifunctional, organic carboxylic acids, are used , whereby the lower alkaline agents are brought into effect simultaneously or after the esterases.
