Definitions
- the present invention relates to the use of a combination of water-soluble builder systems and certain acylhydrazones to improve stain removal, especially bleachable, hydrophilic stains such as red wine stains, tea stains, red fruit stains or beverages and foods thereof, or those containing corresponding dyes, from laundry detergents Washing textiles or cleaning hard surfaces, as well as detergents containing such a combination.
- acylhydrazones as bleach catalyst, as described in WO 2013/104631 A1, leads to improved removal of the abovementioned stains, even at low temperatures.
- the optimal effect depends on the interaction with other components of the formulation.
- the cleaning performance in formulations in which the bleach catalyst is used in combination with a water-soluble builder system is improved.
- a first subject of the invention is therefore the use of a combination of a water-soluble builder system with an acylhydrazone of the general formula (I),
