The invention relates to co-granules containing a granule core and a sheath or coating layer surrounding the granule core. Said co-granules are characterized in that the granule core contains a) at least one bleach activator, a2) between 0 and 20 wt. % of the total quantity of at least one bleach catalyst contained in the co-granule, and c) at least one binding agent, and the sheath or coating layer contains d) between 80 and 100 wt. % of the total quantity of the at least one bleach catalyst contained in the co-granule, and e) at least one coating agent. The co-granules are advantageously suitable for producing cleaning products and detergents and especially products for washing crockery in a machine.

摘要:
The invention relates to washing and cleaning agents comprising a combination of chlorophyllase and a further hydrolase, preferably a lipase, particularly a galactolipase. The combination of chlorophyllase and galactolipase improves the cleaning power, particularly for chlorophyll-containing stains, compared to each of the two enzymes alone.
摘要:
The invention relates to a method for producing bifunctional ammonium nitriles by reacting a dihalogenalkyl compound or a dihalogenaryl compound with a dialkylaminoacetonitrile in a polar, aprotic solvent. Bifunctional ammonium nitriles may be used as bleach activators in detergents and cleaners.
