<P>PROBLEM TO BE SOLVED: To provide a method for producing a perfume capsule particle which has high encapsulation efficiency when perfume is compounded at a high rate while using a spray-drying method with good productivity and an aroma composition and a detergent composition both having such particle compounded therein. <P>SOLUTION: The method for producing a perfume capsule particle comprises emulsifying perfume in a solution wherein a water-soluble matrix-forming agent is dispersed or dissolved and spray-drying the resultant, wherein the amount of perfume compounded X(-) in 1 g of the solid content, the average diameter d(μm) of emulsified oil droplets, and the average particle diameter D(μm) of perfume particles obtained by spray-drying satisfy formula (I): 5,000≥((D/X)/d)≥50. The aroma composition containing the perfume capsule particle produced by the method, and the detergent composition containing the aroma composition and a surfactant are provided. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
