Abstract
A rinse agent composition containing: (a) a gemini surfactant corresponding to formula I: R—CHOH—CH2—[OCH2CH2]x—O—CH2—CHOH—R (I) 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: R1O[CH2(CH3)CHO]q(CH2CH2O)rH (II) 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.
