Abstract
The use is claimed of aminoacetones or salts thereof of the general formulae (I) and (II) in which R1 and R2 are each independently hydrogen, C1-C22-alkyl, C2-C22-alkenyl, phenyl or C5-C8-cycloalkyl, or R1 and R2, together with the nitrogen atom, form a 5-, 6- or 7-membered ring system, X′ is anion, for example chloride, bromide, iodide, toluenesulfonate, benzenesulfonate, cumenesulfonate, mesitylsulfonate, sulfate, hydrogensulfate, acetate, fatty acid anion or anion of polycarboxylates, as a bleaching booster for inorganic peroxygen compounds in the pH range from 7 to 9.
Claims10
A process for boosting the effectiveness of inorganic peroxygen compounds comprising the step of adding at least one salt of at least one aminoacetone of the formula (I)
- wherein R1 and R2,independently of one another, are hydrogen, C1-C22-alkyl, C2-C22-alkenyl, phenyl or C5-C8-cycloalkyl, or R1 and R2, together with the nitrogen atom, form a 5, 6 or 7-membered ring system, to an aqueous bath in the pH range 7 to 9.
A bleaching system consisting essentially of at least one salt of at least one aminoacetone of the formula (I)
- wherein R1 and R2, independently of one another, are hydrogen, C1-C22-alkyl, C2-C22-alkenyl, phenyl or C5-C8-cycloalkyl, or R1 and R2, together with the nitrogen atom, form a 5, 6 or 7-membered ring system and an inorganic peroxygen compound.
A bleaching compound consisting essentially of a carrier material onto which at least one salt of at least one aminoacetone of the formula (I)
- wherein R1 and R2, independently of one another, are hydrogen, C1-C22-alkyl, C2-C22-alkenyl, phenyl or C5-C8-cycloalkyl, or R1 and R2, together with the nitrogen atom, form a 5, 6 or 7-membered ring system is applied.
A washing, bleaching or cleaning composition comprising at least one salt of at least one aminoacetone of the formula (I)
- wherein R1 and R2, independently of one another, are hydrogen, C1-C22-alkyl, C2-C22-alkenyl, phenyl or C5-C8-cycloalkyl, or R1 and R2, together with the nitrogen atom, form a 5, 6 or 7-membered ring system.
