| 摘要 |
The disclosed invention relates to mixtures of at least two structurally different surface-active compounds, one surface-active compound a) being selected from an hydroxyl mixed ether compound of formula (I): <?in-line-formulae description="In-line Formulae" end="lead"?>R<SUP>1</SUP>O[CH<SUB>2</SUB>CH<SUB>2</SUB>O]<SUB>x</SUB>CH<SUB>2</SUB>CH(OM)R<SUP>2</SUP> (I) <?in-line-formulae description="In-line Formulae" end="tail"?> in which R<SUP>1 </SUP>is a linear or branched alkyl and/or alkenyl group containing 4 to 22 carbon atoms or an R<SUP>2</SUP>-CH(OH)CH<SUB>2 </SUB>group, where R<SUP>2 </SUP>is a linear or branched alkyl and/or alkenyl group containing 8 to 16 carbon atoms, x is a number from 40 to 80 and M is a hydrogen atom or a saturated alkyl group containing 1 to 18 carbon atoms. The second surface-active compound b) is preferably selected from a structurally different hydroxy mixed ether compound of formula (II): <?in-line-formulae description="In-line Formulae" end="lead"?>R<SUP>3</SUP>O[CH<SUB>2</SUB>CH<SUB>2</SUB>O]<SUB>y</SUB>[CH<SUB>2</SUB>CHCH<SUB>3</SUB>O]<SUB>z</SUB>CH<SUB>2</SUB>CH(OH)R<SUP>4</SUP> (II) <?in-line-formulae description="In-line Formulae" end="tail"?> These mixtures are capable of improving the drying of hard surfaces after washing and, at the same time, also positively influence clear-rinse performance.
