ABSTRACT:
The method for producing nonionic detergent granules includes the steps of (I) blending the following (i) to (iii): (i) at least one of a nonionic surfactant and an aqueous nonionic surfactant solution; (ii) an acid precursor of an anionic surfactant capable of having a lamellar orientation; (iii) at least one of an alkali builder and an alkali, porous oil-absorbing carrier, to give a mixture of detergent starting materials containing the nonionic surfactant as a main surfactant component; and (II) heating the mixture obtained in step (I) at least up to a temperature capable of neutralizing the acid precursor of the anionic surfactant in an agitating mixer, and granulating while tumbling the agitating mixer thereby increasing a bulk density, to give nonionic detergent granules having a bulk density of from 0.6 to 1.2 g/ml.
