Abstract
A stable moulding material and spinning material containing cellulose, a tertiary amine-oxide, particularly N-methylmorpholine-N-oxide and optionally water, as well as a stabiliser, characterized in that as said stabiliser a mixture of glucosides of gallic acid and m-digallic acid is provided. The stabiliser employed according to the invention is superior to gallic acid propyl ester in the longterm-stabilisation of cellulose dissolved in a tertiary amine-oxide.
