DEFINITION

Classification: 508/487

With organic nitrogen or phosphorus compound:

(under subclass 486) Compositions which contain, in addition to the specified carboxylic acid ester, an organic nitrogen compound or an organic phosphorus compound.

(1) Note. An organic nitrogen compound is one wherein nitrogen is attached directly or indirectly by nonionic bonding to carbon of an organic compound. Similar considerations apply to an organic phosphorus compound.
