Abstract
Detergent compositions particularly useful in hard-surface cleaning comprise an alkanol ethoxylate component which consists essentially of a mixture of compounds of the formula R--O--CH.sub.2 CH.sub.2 O--.sub.x H, wherein R is an alkyl group of from 8 to 18 carbon atoms, said alkyl group having a linear carbon chain in at least about 50 percent of the ethoxylate molecules; wherein the --O--CH.sub.2 --CH.sub.2 --O--.sub.x H ether substituent is, in at least 40 percent of the molecules of the mixture, bound to R at a carbon atom which is neither a terminal carbon atom nor a carbon atom adjacent to a terminal carbon atom; and wherein x has an average value for all ethoxylate molecules of the mixture which is in the range from about 3 to 9; said ethoxylate component being further characterized as having a hydrophile-lipophile balance that is between about 10.4 and 12.0; and said composition being further characterized as containing less than about 2 percent by mole, calculated on moles of the mixture of ethoxylate compounds therein, of compounds having a C.sub.8 to C.sub.18 alkyl group substituted by multiple ether substituents.
