DETERGENT PARTICLES, PROCESS FOR PREPARING THE SAME, AND DETERGENT COMPOSITION HAVING HIGH BULK DENSITY

摘要

Detergent particles comprising a non-soap, anionic surfactant and an inorganic salt not detected by X-ray diffractometry, wherein the molar ratio of the inorganic salt to the surfactant is (0.1 to 1.0):1; and a process for preparing detergent particles comprising the step of dry neutralizing a liquid acid precursor of a non-soap, anionic surfactant with a water-soluble solid alkaline inorganic material, wherein an inorganic acid is used in an amount of 0.1 to 1.0 mol per mol of the liquid acid precursor of the surfactant. The detergent particles are featured by having very low particle tackiness and more pores, and the use of the same results in the formation of a detergent composition with a small diameter and a high bulk density in a high yield.
