| 摘要 |
The invention relates to the use of an alkaline aqueous composition comprising a) an amine oxide b) a nonionic surfactant, not being an amine oxide, and c) a cationic hydrotrope having the formula (I), where R=C6-C22 hydrocarbyl, R1 and R2 are independently C1-C4 alkyl, n is at least 12, and at most 25, and X- is an anion, e.g. halide or methylsulphate; for removal of dirt from hard surfaces. In particular the composition significantly reduces the amount of traffic film remaining on the surface after brushless vehicle cleaning as compared to presently applied formulation concepts. Further, the invention relates to certain such compositions and intermediates to make these.
