  • Patent number: 6335313
    Abstract: In the detergent granules including 10% by weight or more of a nonionic surfactant and 1% by weight or more of a crystalline alkali metal silicate having an average particle size of from 1 to 60 &mgr;m, the detergent granules characterized in that a proportion of the nonionic surfactant to the crystalline alkali metal silicate is in a weight ratio of from 20/1 to 1/20, and that the iron content calculated as Fe in the crystalline alkali metal silicate is 140 ppm or less. The granular detergent composition characterized in that the granular detergent composition includes the detergent granules described above.

  • Patent number: 6239095
    Abstract: A process for the preparation of coated peroxygen compounds, in particular sodium percarbonate, by fluidized bed coating. By using a fluidized bed reactor with a radial inflow base, the passage openings of which allow the fluidized bed gas to emerge in the region of the opening at an angle of less than 35°, measured with respect to the horizontal, in the form of directed part streams, and in which are arranged spray nozzles, the pulse of which points in the same direction as the pulse of the fluidizing gas, it is possible to obtain products with an increased active oxygen stability. A circular reactor, the inflow base of which has lamellae overlapping like turbine blades and nozzles aligned in the direction of rotation of the fluidized bed is preferred.

  • Patent number: 6211138
    Abstract: A non-tower process for continuously preparing granular detergent compositions having a density of at least of about 600 g/l comprises the steps of (a) dispersing a surfactant, and coating the surfactant with fine powder having a diameter from 0.1 to 500 microns, while wetting the surfactant coated with the fine powder with finely atomized liquid, in a mixer, wherein first agglomerates are formed and (b) granulating the first agglomerates in one or more fluidizing apparatus.

  • Patent number: 6184193
    Abstract: A shrinkage prevention agent for water washing of clothing that would conventionally have been dry cleaned. The shrinkage prevention agent is compromised of a steam or vacuum dry-distilled liquid of two or more plants selected from sagebrush, beefsteak plant, tea, plantaginales, aloe, chrysanthemum, pine, cedar, cypress. The shrinkage prevention agent is used in a wet cleaning system that includes water washing.

  • Patent number: 6156719
    Abstract: A non-tower process for continuously preparing granular detergent composition having a low density, preferably about 300 g/l to about 600 g/l is provided. The process comprises the steps of (a) (i) dispersing an aqueous or non-aqueous surfactant, and (ii) coating the surfactant with fine powders having a diameter from 0.1 to 500 microns, in the mixer which is operated under certain conditions to obtain irregular shape granules and excessive fine powders and, (b) spraying on finely atomized liquid to the irregular shape granules and excessive fine powders from step (a), in a mixer which is operated under certain conditions to bind the excessive fine powders onto the irregular-shaped granules.
