IMPROVED RINSE-AID COMPOSITION COMPRISING A BLEND OF NONIONIC SURFACTANTS

摘要

An aqueous rinse-aid composition for kitchen utensils is provided wherein an anionic hydrotrope and a blend of two specifically defined nonionic surfacta nts are utilized which has been shown through empirical research to surprisingly yie ld improved results. One of the nonionic surfactants is an alcohol alkoxylate (as define d) and the other nonionic surfactant is a block copolymer of ethylene oxide and propyle ne oxide (as defined). The composition is suitable for use at a temperature of up to at l east 180.degree.F. in the absence of excessive foaming, spotting and film formation. The component s of the composition exhibit good compatibility during storage even if elevated tempe ratures are experienced thereby maintaining reliable performance upon usage. Rapid high velocity rinsing at a high temperature is made possible in the absence of deleterious foam generation to yield dishes and tableware that can be readily dried without t he need for the time consuming hand removal of deleterious spots and/or film.
