Abstract

A process for controlling the deposition of stickies from paper stock suspensions during papermaking by adding to the paper stock suspensions from 0.001% to 5.0% by weight based on the weight of fibrous paper stock, of alkoxylation products obtained by reaction of alkylene oxides with C.sub.10-22 carboxylic acid derivatives or C.sub.10-22 carboxylic acids containing functional groups with at least one OH group in the 9, 10, 13 or 14 position.
