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.degree. 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) 5 to 20% by weight of an amorphous oil-absorbing carrier containing at least 30% by weight of silicon (in terms of SiO.sub.2) 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.
