• Comparative Examples 1 to 10 were powder detergents for clothing that were inferior in foaming and / or rinsing properties after soaking.
• the mass of the powder detergent composition for clothing remaining on the sieve was measured. Let this value be Xg.
• the mass of the powder detergent composition for clothing that passed through the sieve was measured. This value is Yg.
• the value of the sieve passing rate (%) is preferably 30% or more.
• the sieving passage rate (%) is more preferably closer to 100%.
• the powder detergent composition for clothing of Example 13 had a sieve passing rate of 100% and had good storage stability.
