Nonionic powdery detergent composition and process for producing the same
 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).
