Abstract

The oil-in-water emulsion contains, besides the usual components, xylitol and sorbitol to inhibit water staining. The inhibitor is fully effective even when 1000 parts by weight of the emulsion contain only 1-30 parts by weight each of xylitol and sorbitol. By making this addition of inhibitor the reaction of the water phase with the metal surface freshly created by rolling is to a large degree eliminated and with that also the elimination of the formation of undesirable water stains on the surface of the strip.
