摘要:
A process for preparation of co-granules including one or more bleach activators and one or more bleach agent compounds is described. The bleach component is mixed and coated with a binder selected from the group of fatty acids, fatty acid polyol esters, polyglycols and fatty alcohol oxalkylates. One or more bleach activators is added to this mixture followed by granulation or agglomeration in a mixer, resulting in a bleach co-granule composition including the bleach activator and peroxide components.
摘要:
The invention relates to co-granules containing a granule core and a sheath or coating layer surrounding the granule core. Said co-granules are characterised 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 additives in the form of non-ionic polyesters comprising terephthalic acid, ethylene glycol, polyethylene glycol, optionally propylene glycol, C—C-alkyl-polyalkene glycol ether, and a multifunctional cross-linked monomer. Said polyesters preferably have a flow factor ff of greater than 8, and preferably have a melting point of over 40° C. and molecular weights Mp of 4,000 to 15,000 g/mol. Said polyesters are suitable as soil release components in detergents and cleaning agents.

A process is claimed for preparing granulated acyloxybenzenesulfonates which consists in granulating a mixture composed essentially of acyloxybenzenesulfonate and optical brightener.
摘要:
The present invention relates to 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 invention relates to a comb polymer made of a polymer main chain and polyester side chains linked to said polymer main chain via ester groups, characterized in that (i) the polymer main chain is a polycarbolic acid or a copolymer polycarbolic acid (A), (ii) the polyester side chains comprises the components (B1) C8-dicarbolic acids, optionally sulfonated, (B2) dioles and/or polyolethers having 2 OH groups, and (C) non-ionic terminal groups of the formula -0-(AO)xR, where A means ethylene, propylene, or butylene, x is a number from 1 to 100, and R is a hydrocarbon radical having 1 to 30 C atoms; (iii) the total percent by mass of the polyester side chains B1+B2+C is 80 to 99.9%, relative to the total mass of the comb polymer; (iv) the polyester side chains are obtained from an esterification reaction of the components B1, B2, and C at a mass ratio B1+B2/C of 2:1 to 100:1.
