Abstract
The invention relates to rinse agents containing mixtures of gemini surfactants and fatty alcohol alkoxylates, optionally in conjunction with typical rinse agent ingredients, and to the use of these mixtures for improving wetting behavior in rinse agents.
Claims7
Rinse agents containing
- a. gemini surfactants corresponding to formula (I)
- R—CHOH—CH2—[OCH2CH2]x—O—CH2—CHOH—R (I)
- in which R is a linear or branched alkyl and/or alkenyl group containing 4 to 22 carbon atoms and x is a number of 5 to 90, and
- b. fatty alcohol alkoxylates corresponding to formula (II):
- R1O[CH2(CH3)CHO]q(CH2CH2O)rH (II)
- in which R1 is a linear or branched alkyl and/or alkenyl group containing 4 to 22 carbon atoms and q is 0 or a number of 1 to 10 and r is a number of 1 to 50,
- and optionally other ingredients typically present in rinse agents, characterized in that components a and b are present in a ratio of 1:1 to 4:1.
