The new restriction on 1,4-dichlorobenzene (DCB or PDCB) was published in the Official Journal of the European Union on 9 May 2014 as Regulation (EU) No 474/2014. The Regulation is an amendment to REACH, adding the new restriction to Annex XVII as entry 64.
From 1 June 2015, air fresheners or deodorisers in toilets, homes, offices or other indoor public areas cannot contain DCB equal to or greater than 1% by weight.
DCB can be found in air fresheners and toilet blocks which are designed to mask odours. These products may contain up to 99% DCB. However, DCB is classified as a category 2 carcinogen, an eye irritant that is also hazardous to the aquatic environment. Therefore, the new restriction will help towards reducing the health risks associated with the exposure of this substance by consumers at home as well as professional workers in public toilets.
