GRANULES FOR CARRYING SURFACTANT AND METHOD FOR PRODUCING THE SAME

摘要

method for producing granules for carrying a surfactant comprising a step of preparing a solution or a slurry containing a water-soluble polymer and a water-soluble salt to provide a first liquid preparation, a subsequent step of subjecting the first liquid preparation to a treatment for increasing the number of particles of the water-soluble salt, to thereby prepare a second liquid preparation having an increased number of particles as compared to the number of particles of the water-soluble salt in the first liquid preparation, and another step of subjecting the second liquid preparation to spray drying; granules for carrying a surfactant obtainable by using the method; high bulk density detergent particles using such granules for carrying a surfactant; and a method for producing such detergent particles. The method for producing granules can be employed for providing particles for carrying a surfactant which are excellent in carrying ability (carrying capacity/holding power) and particles for carrying a surfactant which are excellent in absorbing characteristics (carrying speed). Detergent particles having excellent detergency, good quality and the like can be produced with good efficiency, by carrying a liquid surfactant composition on the above particles for carrying a surfactant.
