New polyglycol compounds are provided which are amphoteric derivatives of polyglycol compounds containing (a) an aliphatic hydrocarbon residue containing 12 to 24 carbon atoms, which is bound to nitrogen, and (b) -(CH2-CH2-O-)k groups bound to nitrogen, where k is a whole positive number, the molecule containing in all 4 to 12 -CH2-CH2-O- groups, which polyglycol compounds are, on one hand, quaternated with organic halogen compounds and esterified with at least dibasic oxygen acids with formation of acid ester groups. The compounds of the present invention are especially useful as dyeing auxiliaries, and more particularly, as levelling agents for the dyeing of wool. |
