Abstract
An aqueous solution contains a nonionic surfactant, a alkyl phenoxy polyethoxy phosphate and an alkyl glucoside selected from a group consisting of alkyl glucosides characterized by the alkyl group having eight or fewer carbons and when the alkyl group has eight carbons it is a branched alkyl having a linear six carbon chain with a two carbon branch, where the aqueous solution is further characterized by containing less than 0.3 weight-percent cumene sulfonic acid or its alkali salt based on total aqueous solution weight and the alkyl glucoside is present at a concentration greater than alkyl glucosides having an alkyl group with more than eight carbons, as well as its uses for increasing the cloud point and decreasing the foaming properties.
