2. An additive according to claim 1, which is an amine.
3. An additive according to claim 1, which is an ammonium compound.
4. An additive according to any preceding claim, wherein the alkylene portions of the polyoxyalkylene nitrogen containing compound are the same.
5. An additive according to any preceding claim, wherein the alkylene portions of the polyoxyalkylene nitrogen containing compound are selected from ethylene and propylene groups.
6. An additive according to any preceding claim, wherein the alkylene portions of the polyoxyalkylene nitrogen containing compound are ethylene groups.
7. An additive according to any preceding claim, wherein the nitrogen portion of the polyoxyalkylene nitrogen containing compound is substituted by at least one polyoxyalkylene group and at least one optionally substituted alkyl group.
8. An additive according to any preceding claim, wherein the alkyl group is substituted by one or more hydroxy groups and/or halogen atoms.
