This webinar will provide an introduction to Chemical Substances of Unknown or Variable Composition, Complex Reaction Products and Biological Materials (UVCB) using refined oil products as an example. Due to their complex and variable composition these products are hard to define chemically which leads to challenges in their regulation under Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) the main chemicals regulatory legislation for EU members. Currently the oil refinery industry categorises these products according to the process used in their manufacture and by chemical composition. While chemicals of known hazard (e.g. benzene and polycyclic hydrocarbons) are removed prior to sale that still leaves a lot of chemicals, little or untested for toxicity, contained in a complex mixture. Other examples of UVCB products are products perhaps not immediately apparent as being in this category such as kitchen cooking oils and perfumes. Together they define about 21% of the registered products under REACH. In this seminar we will look at some of the challenges these products pose for regulation and in brief one project that is exploring alternative options to facilitate regulation without causing under testing needs or burden. The webinar is aimed at anyone with an interest in chemicals, toxicity testing methods and chemical regulation.
