  • Publication number: 20100022437
    Abstract: Agglomerating carrier materials in the presence of a granulation liquid with a carbohydrate content and subsequent incorporation of a liquid, such as a perfume oil, yields fluid-containing particles that, even at an elevated liquid loading, exhibit very good powder properties and reliably retain the incorporated liquid even in aggressive solid matrices. These fluid-containing particles may be used, for example, for fragrancing purposes.

  • Publication number: 20080293609
    Abstract: A method to obtain particles which can absorb large quantities of perfume. The resulting particles are mechanically stable, flow freely, and have no tendency to stick together even when being charged with a great quantity of perfume. The perfume can be stabilized in the particles in such a way that the contained fragrances essentially do not decompose. Also disclosed are the aftertreatment of such particles as well as a detergent composition containing the inventive particles.

  • Publication number: 20070117737
    Abstract: Particles, particularly washing, cleaning and/or care product particles, particularly washing, cleaning and/or care product particles, having a bulk weight greater than 450 g/l, particularly 500 g/l to 1200 g/l, characterized in that the particles have a compound mixture and fine-particulate surfactant particles, which have a particle diameter d50 ranging from 0.05 mm to 0.6 mm, a dust value of =0% to a maximum of 0.1%, at least 1% by weight to a maximum of 30% by weight of a surfactant, and at least 10% by weight to a maximum of 40% by weight of sodium carbonate. The indicated weights refer to the total weight of the fine-particulate surfactant particles, comprise, at least in part, discrete surfactant particles, and have a dust value ranging from =0% to =0.2%.

  • Patent number: 6221824
    Abstract: The storage stability of bleach-activating acetonitrile derivatives in solid detergent compositions was to be improved. This was essentially achieved by the use of compounded compounds corresponding to formula R1R2R3NxCH2CN X−, in which R1, R2 and R3 independently of one another represent an alkyl, alkenyl or aryl group containing 1 to 18 carbon atoms, in addition to which the groups R2 and R3 may even be part of a heterocycle including the N atom and optionally other hetero atoms, and X is a charge-equalizing anion. “Compounds” of this type are produced by drying in vacuo, for which purpose a suspension of the acetonitrile derivative and a solid carrier material is introduced into a mixer and the resulting mixture is dried with superheated vapor. Dishwashing detergents, more particularly machine dishwashing detergents, contain about 1% by weight to 10% by weight of this bleach boosting compound.

  • Patent number: 6200498
    Abstract: A process for producing pourable foam regulator granules containing a defoamer combination of a paraffin wax and a bisamide derived from diamines and carboxylic acids and an inorganic, water-soluble or water-dispersible carrier salt by pelletizing in a granulation mixer with intensive mixing 50 to 100 parts by weight of the inorganic carrier salt optionally with up to 5 parts by weight of an anionic or nonionic cellulose ether, adding 1 to 10 parts by weight of an aqueous alkali metal silicate or polymeric polycarboxylate solution and then adding 10 parts by weight of the defoamer combination heated to a temperature of 70° C. to 180° C.

  • Patent number: 6034050
    Abstract: A process for producing an anionic surfactant-containing alkali metal silicate-alkali metal carbonate compound providing multiple wash cycle performance, wherein the compound contains 15% to 50% by weight of alkali metal silicate which is x-ray amorphous and has a molar M.sub.2 O to SiO.sub.2 ratio of 1:1.5 to 1:3.3 and M represents an alkali metal, 30% to 70% by weight of alkali metal carbonate, 1.5% to 15% by weight of anionic surfactant and 12% to 19% by weight of water, by providing a powder component selected from alkali metal carbonate, alkali metal silicate, or a mixture of alkali metal carbonate and alkali metal silicate, and agglomerating the powder component with an aqueous composition containing one or more anionic surfactants.
