The present invention provides a powdery plant vitalizer and a powdery plant vitalizer composition which are resistant to the oozing of effective components and from which effective components are easily dispersed when the vertilizer is in contact with water to give vitality to plants. Specifically, the present invention relates to a powdery plant vitalizer containing a particle containing at least one compound (A) selected from a specific monohydric or dihydric alcohol (A1), a specific ether compound (A2), a specific fatty acid or its ester compound (A3), a specific organic acid derivative (A4) and a glycerin derivative (A5), an emulsifying-dispersing agent (B) and water-soluble sugars (C) or a particle containing the component (A) and water-soluble sugars (C') having an emulsifying and dispersing function, the particle having a structure in which the component (A) is dispersed in the form of an oil droplet in the particle, to a method of producing the powdery fertilizer and to a powdery plant fertilizer composition containing at least one selected from these powdery plant fertilizers and a fertilizer component.

The powder composition for paper manufacturing of the invention contains a hydrophobic organic compound (A), an emulsifying and dispersing agent (B), and optionally water-soluble saccharides (C) added based on necessity and has an average particle diameter of 0.1 to 2,000 &#x3bc;m.

Powder composition for paper manufacturing

Enzyme granules are provided in which an enzyme is rapidly eluted, without insoluble remnants, and generation of powdery dust is suppressed, and which granules have a property such that classification phenomenon generated among the granules in a detergent composition is less likely to take place, in a case where the enzyme granules are formulated together with other components in a detergent. The enzyme granule comprise (A) water-insoluble substance and or a slightly water-soluble substance; (B) a water-soluble binder; and (C) an enzyme. A dye may also be present for coloring. The content of (A) component is 45% by weight or more, and the enzyme granules have an average particle size of from 150 to 500 &mgr;m and a bulk density of from 500 to 1,000 g/L, and have a structure such that more amount of (B) component is present near the surface of the enzyme granules than in the inner portion thereof. The enzyme granule may be aggregated to form an enzyme granule aggregate. A process is provided for preparing the enzyme granule by spray-drying a slurry containing (A), (B) and (C). The enzyme granule aggregate may be prepared by adding an aqueous binding solution to the granules and drying, or by adding molten thermoplastic binder to the granules and cooling.

A process for the production of an alkyl glycoside or an aqueous solution thereof is disclosed, comprising the steps of (1) reacting a sugar with alcohol to obtain an alkyl glycoside reaction product containing unreacted alcohol, (2) establishing a moving liquid film of the alkyl glycoside reaction product and (3) contacting the moving liquid film with steam or an inert gas at a temperature of from 50.degree. to 200.degree. C. The alkyl glycoside or aqueous solution thus obtained contains little unreacted alcohol and is excellent in hue and odor.
