Quaternary ammonium salts and hydroxides; lecithins and other phosphoaminolipids, whether or not chemically defined
In plain English
This category covers quaternary ammonium salts and hydroxides, as well as lecithins and other phosphoaminolipids, regardless of whether they are chemically defined. Specific items include choline and its salts, tetraethylammonium perfluorooctane sulphonate, and didecyldimethylammonium perfluorooctane sulphonate. Other quaternary ammonium salts and hydroxides that do not fit into these specific descriptions are also included in this group.
