摘要:
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.
摘要:
A process for preparing solid alkaline earth metal salts of secondary paraffinsulphonic acids is claimed. This process comprises converting an aqueous solution of a secondary paraffinsulphonic acid and an alkaline earth metal hydroxide into solid form by spray drying.
摘要:
What are claimed are synergistically active bleach activator mixtures consisting of a) a hydroxybenzoic acid derivative of the formula 1 in which R is C8-C11-alkyl, and b) tetraacetylethylenediamine and/or 1,5-diacetyl-2,4-dioxo-1,3,5-hexahydrotriazine.
摘要:
The invention relates to an improved bleach activator and bleach activator compositions in the form of granules for use in washing, cleaning and disinfectant compositions. More specifically, the invention relates to granular bleach-activating mixtures that consist substantially of a) a hydroxybenzoic acid derivative of formula (I) in which R is C8-C11-alkyl and b) tetraacetyl ethylene diamine and/or 1,5-diacetyl-2,4-dioxo-1,3,5-hexahydrotriazine, the granules being free of binding agents.
摘要:
Mixtures of bleaching agentsWhat are claimed are synergistically active bleach mixtures consisting ofa) a compound of the formula (1) in which n is 3, 4 or 5, andb) tetraacetylethylenediamine and/or 1,5-diacetyl-2,4-dioxo-1,3,5-hexa-hydrotriazine.
摘要:
Surfactant compounds are claimed which consists essentially of a) fatty alcohol alkoxylates, b) amorphous silica, c) a carrier material and optionally d) an assistant.
摘要:
Process for the preparation of bleach activator granules, which comprises extruding a mixture comprising bleach activator, anionic or nonionic surfactant and polyalkylene glycol at temperatures of from 60 to 80° C. and a pressure of from 10 to 30 bar, and granulating the resultant extrudates at a temperature of from 60 to 80° C. on a spheronizer.
摘要:
A process for producing coated bleach activator granules in which bleach activator base granules are coated with a coating substance and are simultaneously and/or subsequently thermally conditioned.
摘要:
The present invention relates to a process for the preparation of storage-stable granules essentially comprising a bleaching activator and an inorganic binder material, which comprises the process steps: a) mixing of a dry bleaching activator with a dry inorganic binder material, b) pressing of this mixture to give relatively large agglomerates and c) comminution of these agglomerates to the desired particle size. The invention furthermore relates to the use of the granules prepared by the processes in detergents, cleaning compositions, bleaching compositions and disinfectants.
