Abstract
The present invention relates to a composition for use in treating paper, comprising a specific amide polyether group-containing polyorganosiloxane. The present invention can impart superior texture in view of softness, smoothness and the like to wipe paper such as tissue paper, toilet paper or the like, wherein the color of the wipe paper does not change, and water absorbability is not inhibited.
