PURPOSE: To obtain a mercerizing and/or causticizing wetting agent having low foamability, good alkali stability and high shrinkage wetting power by compounding an alkali metal and/or ammonium salt of 2-ethylhexylsulfate, a mixture of terminally blocked polyethers and, optionally, a trialkyl phosphate in specific amounts, respectively. CONSTITUTION: This mercerizing and/or causticizing wetting agent contains 15-30 wt.% of an alkali metal and/or ammonium salt of 2-ethylhexylsulfate, 1-10 wt.% of a terminally blocked polyether mixture comprising (A) a compound of formula I [R<1> and R<2> are each a 1-20C linear alkyl; R<3> is a 1-22C alkyl, alkenyl, cycloalkyl, aryl, arylalkyl or alkylaryl; (n) is 2, 3 or 4; (x) is 2-25] and (B) a compound of formula II [R<4> is an 8-22C alkyl or alkenyl; R<2> , (n) and (x) are each the same as above] in an A:B weight ratio of 0.1-10, preferably 0.9-1.1, and 0-5 wt.% of a 1-6C trialkyl phosphate. |
