Mixtures of gemini surfactants and fatty alcohol alkoxylates in rinse agents

摘要

A rinse agent composition containing: (a) a gemini surfactant corresponding to formula I:; $PTEXTPDATR\—CHOH\—CH/PDATHILSBPDAT2/PDAT/SB/HILPDAT\—\[OCH/PDATHILSBPDAT2/PDAT/SB/HILPDATCH/PDATHILSBPDAT2/PDAT/SB/HILPDAT\]/PDATHILSBPDATx/PDAT/SB/HILPDAT\—O\—CH/PDATHILSBPDAT2/PDAT/SB/HILPDAT\—CHOH\—R\ \ (I)/PDAT/PTEXT$ ;wherein R is a linear or branched alkyl and/or alkenyl radical having from about 4 to 22 carbon atoms, and x is a number from about 5 to 90; and (b) a fatty alcohol alkoxylate corresponding to formula II:; $PTEXTPDATR/PDATHILSPPDAT1/PDAT/SP/HILPDATO\[CH/PDATHILSBPDAT2/PDAT/SB/HILPDAT(CH/PDATHILSBPDAT3/PDAT/SB/HILPDAT)CHO\]/PDATHILSBPDATq/PDAT/SB/HILPDAT(CH/PDATHILSBPDAT2/PDAT/SB/HILPDATCH/PDATHILSBPDAT2/PDAT/SB/HILPDATO)/PDATHILSBPDATr/PDAT/SB/HILPDATH\ \ (II)/PDAT/PTEXT$ ;wherein R¹ is a linear or branched alkyl and/or alkenyl group having from about 4 to 22 carbon atoms, and q is a number up to about 10, and r is a number from about 1 to 50, and wherein (a) and (b) are present in the composition in a ratio by weight of from about 1:1 to 4:1.
