On October 10, 2017, the regulatory news provider Chemical Watch informed about the outcome of the 22nd meeting of the European Chemicals Agency’s (ECHA) Biocidal Products Committee (BPC). The meeting took place on October 3-4, 2017, in Helsinki, Finland.

The BPC adopted ten opinions on application for approval of three active substances, namely chlorophene (CAS 120-32-1), azoxystrobin (CAS 131860-33-8), and polyhexamethylene biguanide hydrochloride with a mean number-average molecular weight of 1415 and a mean polydispersity of 4.7 (PHMB (1415; 4.7), CAS 32289-58-0).

According to a news article published by ECHA on October 5, 2015, PHMB (1415; 4.7) may be approved for product types 2 and 4, but not for 1 (human hygiene), 5 (drinking water), and 6 (preservatives for products during storage). Product type 2 includes disinfectants not intended for direct application to humans or animals, while product type 4 covers disinfectants that are used in the food and feed area.

Azoxystrobin may be approved for product types 7 (film preservatives), 9 (fibre, leather, rubber and polymerized materials preservatives), and 10 (construction materials preservatives).

Chlorophenone cannot be approved for product type 3 (veterinary hygiene). Products of type 2 containing chlorophenone meet the exclusion criteria of the Biocidal Products Regulation (BPR, EU 525/2012) and may only be approved, if the legally defined conditions for derogation are met.

Further information on the 22 biocidal product types is provided by ECHA.
