Abstract
A compound of the formula ##STR1## wherein R is alkyl of 8-22 carbon atoms in the alkyl chain or hydroxyalkyl of 2-22 carbon atoms; and R' and R" each independently is hydrogen or C.sub.1 -C.sub.20 -alkyl provided that R' and R" are not simultaneously hydrogen, and R' and R" in total have 8-20 carbon atoms; and in I, x is 0.5-5 and y is 5-50; and in II, z is freely selectable with the proviso that the sum total of all x for a given z is 0.5-5 and the sum total of all y for a given z is 5-50; and m is 1 or 2.
Claims18
A biodegradable and low-foaming tenside of the formula (I) or (II) ##STR9## wherein when m is 2, R is C.sub.8-22 -divalent alkyl, or when m is 1, R is C.sub.8-22 alkyl or C.sub.2-22 hydroxyalkyl;
- and R' and R" each independently is hydrogen or C.sub.1 -C.sub.20 -alkyl provided that R' and R" are not simultaneously hydrogen, and R' and R" in total have 8-20 carbon atoms;
- x is 0.5-5 and y is 5-50;
- "---" indicates that the individual x units and the individual y units may be attached to the other x and y units in any order;
- and
- m is 1 or 2 for formula (I) and m is 1 for formula (II).
