The powder composition for paper manufacturing of the invention contains a hydrophobic organic compound (A), an emulsifying and dispersing agent (B), and optionally water-soluble saccharides (C) added based on necessity and has an average particle diameter of 0.1 to 2,000 &#x3bc;m.

Powder composition for paper manufacturing

A high-density detergent composition comprises 10 to 60% by weight of a surfactant composition having a weight ratio of an anionic surfactant to a nonionic surfactant of 4:10 or more and 10:0 or less, wherein the high-density detergent composition has a bulk density of from 600 to 1200 g/L, and has a total summation of a product of a mass base frequency Wi and a dissolving rate Vi of each group of classified granules obtained by classifying detergent granules by using a classifier, which satisfies the following formula: &#x3a3;(Wi&#xb7;Vi)&#x2267;95(%), and wherein a mass base frequency of the classified granules having a size of less than 125 &#x3bc;m is 0.1 or less, wherein the classifier comprises sieves each having a sieve-opening 2000 &#x3bc;m, 1410 &#x3bc;m, 1000 &#x3bc;m, 710 &#x3bc;m, 500 &#x3bc;m, 355 &#x3bc;m, 250 &#x3bc;m, 180 &#x3bc;m, and 125 &#x3bc;m, and a receiver.
