Piperonyl butoxide (PBO) is a biocidal active substance

The European Chemicals Agency (ECHA) has announced that piperonyl butoxide (PBO) is to be considered as a biocidal active substance and not merely as a synergist or co-formulant. All provisions applicable to a biocidal active substance will apply to PBO. As a consequence, from 1 September 2015, biocidal products containing PBO can only remain on the EU market if the PBO source is listed on ECHA’s Article 95 list. The decision on PBO was made at the meeting of representatives of Member State competent authorities for the implementation of the Biocidal Products Regulation in March 2015, following the conclusions of the Biocidal Products Committee in December 2014. A copy of the Article 95 list is available at: Article 95 list
