Biocidal Products Regulations (BPR) and How Water Treatment Products Complies

BPRThe Biocidal Products Regulations (BPR) is a piece of European-wide legislation that has now replaced the Biocidal Products Directive (BPD). The aim of this newly implemented legislation is to simplify and streamline existing EU requirements without reducing the level of production to health and the environment set out under older legislation (BPD).

The new EU Biocides Regulation retains the basic structure of the BPD – a two-step procedure for approving active substances at EU level and authorising biocidal products in Member States.

In short, the BPR carries on the work of the BPD more efficiently and ensures biocidal products are assessed for their safety with regards to people, animals and the environment before they are placed on the market. The legislation also acts to stop “Free Riders” from supplying sub-standard products into the market.

The Aims of the BPR are as follows:

  • To provide a high level of protection for humans, animals and the environment from the use of biocidal products through risk assessment. The active biocidal substances each require the submission and evaluation of data relating to the chemistry, toxicity and environmental fate.
  • To harmonise the European market for biocidal products and their active substances such that product authorisation in one Member State is recognised by other Member states, this is the principle of mutual recognition.
  • To ensure that biocidal products on the market are sufficiently effective against the target species.


Biocidal products are defined as those active substances and preparations containing one or more active substances intended to destroy, deter, render harmless, prevent the action or otherwise exert a controlling effect on any harmful organism by chemical or biological means.

The BPR covers 23 different product types which includes disinfectants, preservatives, pest control and antifouling products. For example Liquid Cooling and processing systems are included in Product Type 11.


Biocidal products require product authorisation or product registration within two years of an active substance being formally included on to Annex 1 or 1A of the BPR. During the transition phase the biocidal products fall under national legislation.

Water Treatment Products only uses biocidal active substances which are supported for review in the appropriate product types under the BPR review program.

Water Treatment Products is committed to work with biocidal active suppliers and consortia that meet BPR criteria and obtains guidance from the Health and Safety Executive which is the UK Competent Authority for the EU Biocidal Products Directive (BPD) (98/8/EC) and is responsible in implementing the Biocidal Products Regulations 2001 (BPR).
