PROBLEM TO BE SOLVED: To provide a solid cleaning composition which is derived from amino acid and has good appearance and improved sense of use. SOLUTION: The solid cleaning composition includes a salt of N-acylamino acid as the main component. Counter ions to the N-acylamino acid include 30-60% of a counter ion consisting of ethanol amine, 5-25% of a counter ion selected from the group consisting of N-methyltaurine and hypotaurine, and 25-60% of a counter ion consisting of an alkali metal. The neutralization degree of the N-acylamino acid by the counter ions is 1.7-2.0. COPYRIGHT: (C)2011,JPO&INPIT
