Amine-oxides of the general formula: ##STR1## wherein R.sub.1 and R.sub.2 are alkyl groups with 1 to 4 C-atoms, R.sub.3 is hydrogen, a hydroxyl group or an alkoxy group with 1 to 4 C-atoms and m and n are whole numbers which fulfil the conditions 1.ltoreq.m.ltoreq.8 and 0.ltoreq.n.ltoreq.4 respectively, with the proviso that n is not 0 if R.sub.3 is a hydroxyl group or an alkoxy group, can be used with advantage for the preparation of mouldable or spinnable cellulose solutions which have a reduced tendency to crystallise.
