Definitions
- the present invention relates to the use of certain cyclic Sugar ketones to enhance the bleaching effect of peroxygen compounds when bleaching colored stains both on textiles and on hard surfaces, as well as detergents and cleaning agents, which such contain cyclic sugar ketones.
- Inorganic peroxygen compounds especially hydrogen peroxide and solid peroxygen compounds, which dissolve in water to release hydrogen peroxide, such as sodium perborate and sodium carbonate perhydrate, have long been used as oxidizing agents for disinfection and bleaching purposes.
- the oxidizing effect of these substances in dilute solutions depends strongly on the temperature; For example, with H 2 O 2 or perborate in alkaline bleaching liquors, sufficiently quick bleaching of soiled textiles can only be achieved at temperatures above about 80 ° C.
- transition metal salts and their complexes e.g. in EP 0 392 592, EP 0 443 651, EP 0 458 397, EP 0 544 490 or EP 0 549 271 are described.
