✦ Synopsis

Japan bans 2,6-ditertiary butyl phenol as UV absorber

Under the Chemical Substances Control Law, the Japanese Government has prohibited the manufacture and import of 2,6ditertiary butyl phenol, which had hitherto been widely used as an ultraviolet absorber. The chemical was often included in a formulation of synthetic resins for baths, flooring materials, domestic electrical appliances and paints, with the objective of minimising discoloration by sunlight and artificial (fluorescent) light. For the same reason, it was sometimes used in laminated wood products, waxes, adhesives and air fresheners. In fiscal 2004, Japan manufactured or imported 120 tonnes of 2,6-ditertiary butyl phenol.

A study jointly financed by the Environment Ministry, the Economy, Trade & Industry Ministry, and the Health, Labour & Welfare Ministry revealed that this chemical is bioaccumulative and toxic, particularly affecting the liver. It also quite a persistent hazardous chemical, which does not easily degrade or disintegrate in the natural environment.
