Abstract: The present invention relates to coated particles in which vegetable wax is provided on the surface of starch particles. The coated particles have an average particle diameter d1 of 0.5 to 20 ?m and a maximum particle diameter d2 being less than 30 ?m and less than 4.0 times the average particle diameter d1. The vegetable wax is contained in an amount of 0.5 to 10.0 wt % in the coated particles. Accordingly, particles having excellent feel characteristics and water repellency can be achieved with a natural material having excellent biodegradability. A method for producing coated particles includes: a step of preparing a dispersion that contains 1 to 20 wt % of starch particles; a step of adding vegetable wax to the dispersion and heating and cooling the mixture to precipitate the vegetable wax on the surface of the starch particles; and a step of subjecting this dispersion to solid-liquid separation to obtain coated particles as a solid.

Abstract: A faujasite-type zeolite has an IR spectrum in which the IR spectrum has an absorption band 1 including surface silanol groups and having a local maximum in a range from 3730 cm?1 to 3760 cm?1, and an absorption band 2 including acidic hydroxyl groups and having a local maximum in a range from 3550 cm?1 to 3700 cm?1, a ratio (h1/h2) of a peak height (h1) of the absorption band 1 to a peak height (h2) of the absorption band 2 being less than 1.2.
