    Abstract: A nonionic powdery detergent composition which does not cause any deterioration in the solubility even after storage for a long period of time, comprising (a) 12 to 35% by weight of a nonionic surfactant having specified properties, (b) 5 to 60% by weight of a water-soluble chelating agent, (c) 5 to 20% by weight of an oil-absorbent carrier having specified properties and (d) 2 to 40% by weight of an alkali metal carbonate, and having a water-soluble alkali metal silicate content of less than 5% by weight. This nonionic powdery detergent composition is produced by adding the nonionic surfactant (a) to a mixture comprising the components (b), (c) and (d).

    Abstract: A process for producing nonionic detergent granules having a bulk density of from 0.6 to 1.2 g/ml is disclosed, which comprises the following steps (1) to (3): (1) mixing a detergent material comprising a nonionic surfactant; (2) granulating a mixture obtained in said step (1) by agitating in an agitating mixer provided at the center position thereof with a rotation shaft having an agitation impeller with a clearance between the agitation impeller and an inner wall of the mixer, wherein the agitation impeller agitates the mixture to form an adhesion layer of said mixture on said inner wall of said mixer so as to increase a bulk density of granules of the mixture; and (3) mixing the granules obtained in said step (2) with fine particles to thereby coat the surface of the granules with the fine particles. The nonionic detergent granules containing a nonionic surfactant in a high content and having high bulk density and excellent powder fluidity and non-caking property can be produced in the process of the present invention with less suffering from restriction in the composition.

    Abstract: To provide a nonionic powdery detergent free from oozing of a liquid nonionic surfactant at ambient temperature and having excellent powder fluidity and non-caking properties and a solubility which is not deteriorated with time. The nonionic powdery detergent composition comprises (a) 12 to 35% by weight of a nonionic surfactant having a melting point of not higher than 40 DEG C and an HLB in the range of 9.0 to 16.0, (b) 10 to 60% by weight of a crystalline aluminosilicate and (c) an oil-absorbing carrier containing at least 30% by weight of silicon (in terms of SiO2) versus the weight of said carrier in an anhydrous state and having an oil-absorbing capacity of at least 80 ml/100 g, said carrier giving a dispersion with a pH of at least 9 or being soluble in a 2% aqueous NaOH solution in an amount of 0.5 g or below. i
