Abstract:
A detergent or cleaner which comprises fatty acid alkyl ester alkoxylates having a narrow homolog distribution of fatty acid alkyl ester alkoxylates of the formula 1R1â€”COO(AO)nâ€”R2 where R1 is a straight-chain or branched alkyl or alkenyl group having from 8 to 18 carbon atoms, R2 is C1-C6-alkyl or C2-C6-alkenyl, AO is a C2-C4-alkylene oxide unit, and n is a number from 4 to 10 and the narrow homolog distribution of fatty acid alkyl ester alkoxylates contains less than 14% by weight of compounds with a content of not more than (aâˆ’3) â€”AO groups and less than 16% by weight of compounds with a content of not below (a+3) â€”AO groups where a is the number of â€”AO groups with a maximum frequency, whereby said detergent or cleaner exhibits an improved detergency as measured by delta reflectance.
