Abstract

An aqueous solution comprising a nonionic surfactant, an alkylphenoxypolyethoxyphosphate, and an alkylglucoside selected from the group consisting of alkylglucosides characterized in that: the The alkyl group has eight or fewer carbons, and when the alkyl group has eight carbons, it is a branched chain alkyl group having a linear six-carbon chain with two carbon branches, wherein the aqueous solution is characterized by Further in that it contains less than 0.3% by weight of the total aqueous solution of cumene sulfonic acid or an alkali metal salt thereof, and the alkyl glucoside is at a concentration greater than that of an alkyl glucoside having an alkyl group with more than eight carbons presence; and its use to increase the cloud point and reduce foaming characteristics.

Description

technical field [0001] The present invention relates to an aqueous solution containing a nonionic surfactant and a hydrotrope containing an alkylphenoxy polyethoxy phosphate and an alkyl glucoside. Background technique [0002] One challenge with aqueous cleaning formulations is to achieve formulation stability over a range of environments and temperatures while desirably minimizing foaming. Cleansing formulations often contain one or more nonionic surfactants and may further contain bases such as sodium or potassium hydroxide and other electrolytes. Electrolytes reduce the solubility of nonionic surfactants and destabilize formulations. Also, increasing the temperature tends to destabilize the formulation by reducing the solubility of the nonionic surfactant. Often, hydrotropes are included in formulations to enhance the solubility of nonionic surfactants and to increase formulation stability over the temperature and electrolyte concentration ranges of interest.
