Abstract

Paper towels especially towels having wet strength derived from cationic wet-strength resins are useful for wiping glass surfaces such as windshields of motor vehicles and this usefulness is significantly improved by the incorporation onto the paper towel of a non-ionic surfactant especially ethoxylates of linear secondary alcohols. Preferably the linear alkyl hydrophobe portion of a mixture of secondary alcohols having 11 to 15 carbon atoms and the hydrophylic portion is a polyethylene oxide chain randomly attached to the linear aliphatic chain and having approximately 15 ethylene oxide units.

Claims

1. A WIPER FOR GLASS SURFACE CONSISTING ESSENTIALLY OF A WET-STRENGTHENED PAPER SHEET CONTAINING AN ACTIVE AMOUNT OF A NONIONIC DETERGENT SURFACTANT OF THE FOLLOWING GENERAL FORMULA:

2. The paper sheet of claim 1 wherein the activating amount of detergent surfactant is from about 0.01 to about 2.0%, based upon the dry weight of the paper.

3. A wiper for glass surfaces consisting essentially of wet-strengtened paper sheet containing an active amount of a non-ionic detergent surfactant wherein the non-ionic detergent surfactant is an ethoxylated secondary alcohol produced by ethoxylating a mixture of linear secondary alcohols containing from 11 carbon atoms to 15 carbon atoms with a hydrophylic moiety containing 15 ethylene oxide groups.
