GRANULAR NONIONIC DETERGENT COMPOSITION AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To obtain a granular nonionic detergent composition having improved disintegration properties of detergent particles in washing by immersing and allowing in an immersed state or improved fluidity of detergent particles. SOLUTION: This granulation nonionic detergent composition comprises detergent particles in which granules containing (a) >=10 wt.% of a nonionic surfactant and (b) an aluminosilicate composed of >=50 wt.% P type zeolite are coated with a powdery coating agent having >=10μm average particle diameter and/or detergent particles in which the surfaces of granules containing (a) >=10 wt.% of the nonionic surfactant and (b) the P type zeolite are coated with a powdery coating agent having 0.15-1.3 ml/g oil absorption. The detergent particles have 0.3-5 mg/minute oozing rate of the nonionic surfactant from the granules and the rate of (the oozing rate of the nonionic surfactant from the granules)/(the oil absorption of the powdery coating agent) of 1.6-8.0 g2/ l.minute. The granular nonionic detergent composition is produced by grinding and granulating after kneading and extrusion of the granules or stirring and granulating the granules.
