General information on use; Metilox is the addition product of 2,6-di(tert-butyl)phenol and methylacrylate. It is used as an intermediate in the synthesis of phenolic antioxidants mainly for polymers (ref. 38). This application accounts for 99.8% of the production volume. Other usages known are as an additive in motor oils, hydraulic fluids and as a lubricant. The use of Metilox in consumer products was reported in Denmark (>10% concentrations in not further specified products) and in Sweden (as a lubricant in motor oils). In Canada Metilox is also used in fragrances/perfumes/deodorisers/flavouring agents (ref. 43). The total production volume within OECD member states by the major producer (Ciba) amounted 23,500 tonnes in 1992. Known Metilox production sites are in Switzerland and in the U.S.
