Résumé :	The recent classification of some water soluble cobalt salts as category 2 carcinogens within the EU has prompted much speculation that cobalt carboxylates (such as cobalt 2―ethylhexanoate) traditionally used as the primary drier in alkyd coatings may ultimately be classified in the same way which would effectively end their use in decorative paint formulations. New data on an alternative class of cobalt driers ― cobalt boroacylates will be presented showing these compounds have significantly reduced water solubility compared to the traditional cobalt driers and it will be explained how this reduced solubility makes these compounds an excellent alternative to the traditional driers.
