  • (a) aqueous medium,(b) at least a oxyalkylene derivative of following formula (I) expression,[changing 1]Z-{O(AO) l(EO) m-(BO) nH} a (I) (in the formula, Z represents to remove the residue that the hydroxyl of the chemical compound with 3~

    9 hydroxyls obtains;

    AO represents that carbon number is 3~

    4 oxyalkylene;

    EO represents the oxygen ethylidene;

    BO represents that carbon number is 4 oxyalkylene;
