[0162] (Discussion of Evaluation Results)

[0163] A process of the present invention of mixing the component (A) of hydrophilic nonionic surfactant as a monoether compound of a branched higher alcohol having 12 to 20 carbons and a polyoxyethylene group and the component (B) of water, and then mixing them with the component (C) of hydrophobic powder could provide dispersion liquids in which the hydrophobic powder flows uniformly. On the other hand, in Comparative Examples 5 to 11 in which the hydrophilic nonionic surfactant is used, all the hydrophobic powder could not be dispersed in water and became a clay-like substance on the way. Although Example 29 is a method in which a hydrophilic surfactant is mixed with a hydrophobic powder and then the mixture is added to the aqueous phase, a uniform dispersion liquid could be prepared. All of the comparative examples were non-fluid pastes and did not become uniform dispersion liquids.
