THE USE OF A QUATERNARY AMMONIUM COMPOUND AS A HYDROTROPE AND A COMPOSITION CONTAINING THE QUATERNARY AMMONIUM COMPOUND

摘要

The present invention relates to the use of an alkyl di(lower alkyl) mono(polyoxyethylene) quaternary ammonium compound as a hydrotrope in 5 aqueous solutions for a nonionic surfactant, preferably a C8-C18-alcohol alkoxylate containing 1-20 ethyleneoxy units and 0-5 propyleneoxy units. It also relates to a composition comprising said quaternary ammonium compound and said nonionic surfactant. The cationic surfactant has the formula 10 R2+R (1) N (CH2CH2O)n H X R1 wherein R=C6-C22 alkyl; R1 and R2 are independently a C1-C4 alkyl group; n=8-25; and X- is an anion. The compositions may be used for the cleaning of hard surfaces, for example for vehicle cleaning or machine dishwashing.
