## Abstract

A water-soluble surfactant composition is provided comprising (A) a glycidyl ether-capped acetylenic diol ethoxylate and (B) a polyoxyalkylene alkyl ether having an HLB of 8-18. When compounded in inks and paper coatings, the surfactant composition exerts improved foam controlling, dispersing, wetting and penetrating capabilities, is water soluble, and complies with high-speed printing and application conditions.

## Claims

### Claim 1

A water-soluble surfactant composition comprising
(A) 1 to 60% by weight of a glycidyl ether-capped acetylenic diol ethoxylate having the average compositional formula (1):
wherein R1 is independently hydrogen, a linear C1-C6 alkyl group or branched or cyclic C3-C6 alkyl group; R2 is independently a linear C1-C12 alkyl group or branched or cyclic C3-C12 alkyl group; R3 is —CH2OR4, R4 is independently a linear C2-C30 alkyl group, branched or cyclic C3-C30 alkyl group, C2-C30 alkenyl group, C6-C30 aryl group or C7-C30 aralkyl group; n, m, p and q are positive numbers, n+m has an average value from 1 to 100, and p+q has an average value from 0.5 to 5, and
(B) 40 to 99% by weight of a polyoxyalkylene alkyl ether having the average compositional formula (II):
