The exposure scenarios (where appropriate the use and exposure categories), exposure assessment and risk characterisation shall address all identified uses of the registrant. 5. The chemical safety report need not include consideration of the risks to human health from the following end uses: (a) in food contact materials within the scope of Regulation (EC) No 1935/2004 of the European Parliament and of the Council of 27 October 2004 on materials and articles intended to come into contact with foodOJ L 338, 13.11.2004, p. 4.; (b) in cosmetic products within the scope of Directive 76/768/EEC. 6.
