Process for making a modified granule or powder comprising an alkali metal salt of an aminocarboxylate complexing agent (A), said process comprising the steps of

(a) providing a granule or powder comprising an alkali metal salt of an aminocarboxylate complexing agent (A),
(b) treating said granule or powder with the respective aminocarboxylate complexing agent (A) in which at least one amino group or carboxyl group per molecule is present in the acid form, in the presence or absence of water,
(c) performing a heat treatment at a temperature in the range of from 80 to 150 C.

The invention relates to solidification of liquid nonionic surfactants with a binder, carrier, or both binder and carrier to form a solidified surfactant composition. In particular, the invention relates to solidification of liquid nonionic surfactants utilizing drying device(s), wherein the feed composition contains at least one liquid nonionic surfactant and the binder, carrier, or binder and carrier to form a solidified surfactant composition. The solidified surfactant compositions can be useful in various cleaning compositions.

A process for making a particulate laundry detergent composition, the process includes the steps: (a) contacting water, starch, acid and perfume to form a concentrated aqueous acidic mixture, the concentrated acidic mixture includes: (i) from about 20 wt % to about 60 wt % starch; (ii) from about 10 wt % to about 50 wt % acid; (ii) from about 2 wt % to about 20 wt % perfume; (iv) from 10 wt % to less than about 45 wt % water; the concentrated acidic mixture has a pH of less than about 4.5; (b) subjecting the concentrated acidic mixture to a perfume emulsification step to emulsify the perfume to form an emulsified perfume mixture in fluid form; and (c) spraying the emulsified perfume mixture in fluid form onto base detergent particles so that the emulsified perfume mixture at least partially coats the base detergent particles to form the particulate laundry detergent composition, the base detergent particles include from about 4 wt % to about 60 wt % detersive surfactant.

A process for the preparation of a powder comprising one or more complexing agent salts of the general formula ##STR00001##
comprises atomizing an aqueous solution comprising the one or more complexing agent salts in the presence of a crystalline fine dust of the same complexing agent salts and a drying step, wherein the concentration of the one or more complexing agent salt is from 10 to 80% by weight, based on the total weight of the aqueous solution, with an upper limit for the average particle diameter of the crystalline fine dust which is lower by at least a factor of 2 than the lower limit of the average particle diameter of the powder obtained after the process, and the fraction of the crystalline fine dust is from 0.1 to 20% by weight, based on the weight of the powder obtained after the process.

A method for formulating a cleaning composition contains the step of coating a granular absorbent material with a coating agent to produce a coated absorbent material and mixing the coated absorbent material with a sanitation agent, wherein the coated absorbent material absorbs the sanitation agent to form the cleaning composition. The resulting cleaning composition may be used for cleaning up pathogens or hazardous materials. The cleaning composition may also functions as a liquefiable dry cleaning powder for public areas in response to bodily fluid incidents. A coating method of a non-toxic bio static film on a high surface area solid is disclosed.

A process for making a granule containing (A) at least one chelating agent selected from alkali metal salts of methyl glycine diacetic acid (MGDA) and of iminodisuccinic acid (IDS), and, optionally, (B) at least one homo- or copolymer of (meth) acrylic acid, partially or fully neutralized with alkali, the process including the steps of (a) providing an aqueous solution or slurry containing chelating agent (A) and, if applicable, (co) polymer (B), (b) removing most of the water by spray granulation in a fluidized bed, (c) treating the resultant granule in a vessel of which at least one part rotates around a horizontal axis and wherein the vessel is selected from paddle mixers, free-fall mixers and plough share mixers.

A dissolvable solid article which can include multiple layers of flexible, dissolvable, porous sheets, in which a coating composition including solid particles is present on at least one internal surface of at least one sheet in the solid articles and a process for making such solid articles.
