Water-soluble surfactant compositions
First Claim
1. A water-soluble surfactant composition comprising (A) 10 to 95% by weight of an acetylene glycol of the following formula (1):
-
and/or an acetylene glycol ethoxylate of the following formula (2);
wherein m and n are positive numbers and the sum of m+n is from 2 to 30, and (B) 5 to 90% by weight of at least one polymer selected from polyoxy(ethylene-propylene) block polymers of the following formula (3);
HO(C2H4O)w(C3H6O)x(C2H4O)yH
(3) wherein w, x and y are positive numbers, having a weight average molecular weight of 1,500 to 10,000, an ethylene oxide content of 35 to 90% by weight and a propylene oxide content of 10 to 65% by weight, the composition exhibiting a dynamic surface tension of up to 50 mN/m both at 1 Hz and 10 Hz in a 0.1 wt % aqueous solution thereof.

Abstract
Water-soluble surfactant compositions comprising (A) 2,5,8,11-tetramethyl-6-dodecyne-5,8-diol and/or ethoxylate thereof and (B) a polyoxy(ethylene-propylene) block polymer and exhibiting a dynamic surface tension of up to 50 mN/m both at 1 Hz and 10 Hz in a 0.1 wt % aqueous solution thereof have such surface tension-reducing effects that when added to inks and paper coatings, they provide a surface tension comparable to those of fluorochemical and silicone surfactants. Because of a low dynamic surface tension, the surfactant compositions develop excellent substrate wetting, substrate penetrating and anti-foaming capabilities to comply with high-speed printing and coating, and overcome the environmental problem.
