Abstract: Particles having excellent touch properties are achieved with a water-soluble material having excellent biodegradability. Particles according to the present invention contain a starch having an amylopectin content of 90% by weight or more. The average particle diameter d1 of the panicles is 0.5 to 20 ?m, and the maximum particle diameter d2 is less than 30 ?m while being within 3.0 times the average particle diameter.

Abstract: The present invention provides a compound represented by general formula (I): 1
