| abstract |
The invention relates to the use of N-methyl-N-acylglucamines in compositions for cleaning hard surfaces, having a pH value < 6, the proportion of the glucamines with C8-C14-acyl groups being at least 80 wt. % and the proportion of glucamines with C8-C10-acyl groups is more than 50 wt. %, respectively in relation to the total amount of glucamines. The invention also relates to corresponding compositions. |
