This measure will amend Regulation (EC) No 1223/2009 ('the Cosmetic Regulation') as it applies in Great Britain to lower the threshold for labelling requirements for formaldehyde releasing substances and prohibit the use of 3-(4-Methylbenzylidene)-d1 camphor/Enzacamene (4-MBC) in cosmetic products. The measure will also prohibit 16 new substances that have been classified as carcinogenic, mutagenic and reprotoxic (CMR) substances under Regulation (EC) No 1272/2008 (the GB Classification, Labelling and Packaging (CLP) Regulation).
