    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

    Abstract: A nonionic powdery detergent composition which is free from bleeding of a nonionic surfactant, does not exhibit any deterioration in its solubility even after the passage of time and has an excellent detergency against a fatty acid soil, which comprises 12 to 50% by weight of (a) a nonionic surfactant having a melting point of 40 DEG C or below, 3 to 60% by weight of (b) a specified crystalline layer silicate, and 5 to 30% by weight of (c) a porous oil-absorbent carrier having an oil absorbability of 80 ml/100 g or more, and a process for producing the nonionic powdery detergent composition.

    Abstract: Disclosed is a powdery nonionic detergent product comprising a container and a powdery nonionic detergent composition packaged in the container, wherein the powdery nonionic detergent composition comprises a nonionic surfactant having a melting point of 40.degree.C or lower and an HLB value of 9.0 to 14.0, a crystalline aluminosilicate and a silica base oil-absorptive carrier containing at least 40% by weight of silicon in terms of SiO2 and having an oil absorbing capacity of at least 150 ml/100 mg in specified proportions, and at least a portion of the container's surface which is in contact with the powdery nonionic detergent composition for a long period of time is made of a polymer having a solubility parameter in the range of 7.5 to 11.5 ¢cal/cm3!1/2 and lower than the HLB value of the nonionic surfactant. The powdery nonionic detergent composition does not stick an inner wall surface of the container when the detergent product is stored for a long period of time.

    Abstract: Bleaching agents contg. Na percarbonate (I) coated with a borate-contg. compsn. (II) are claimed. Also claimed are bleaching detergent compsns. contg. 1-99wt.% of (I) coated with (II). (II) may contain 10-100wt.% borate, esp. Na metaborate, opt. together with a sequestering agent (esp. EDTA or NTA) and/or an alkali metal silicate or a Mg cpd. The amt. of (II) may be 0.1-30% of the wt. of (I). Coating (I) with (II) stabilises it against decompsn., esp. in detergent compsns. which have a low or zero phosphate content and/or contain aluminosilicates.

    Abstract: A stable sodium percarbonate having excellent stability when incorporated into a bleaching agent composition or a detergent composition, particularly a zeolite-containing detergent composition. The stable sodium percarbonate is produced by a process which comprises a step of treating sodium percarbonate on the surface with at least one coating agent selected from the group (A) consisting of boric acids, borates and alkali metal silicates and at least one coating agent selected from the group (B) consisting of carbonates, hydrogencarbonates and sulfates, and at least one coating agent selected from the group consisting of coating agents belonging to groups (A) and (B) being present in the form of an aqueous coating slurry thereof.

    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).
