Exponent’s Biocides team boasts a vast wealth of regulatory experience and expertise gained from working in government, industry, contract research organisations, and as independent regulatory consultants. We have a proven track record assisting clients to achieve positive active substance approvals/Annex I inclusions and product authorisations under the EU Biocidal Products Regulation (BPR) and Biocidal Products Directive (BPD). We evaluate and construct product family dossiers under the BPR, have experience analysing global biocide regulatory systems and have assisted clients to achieve authorisations under global national regulations in more than 18 non-EU countries. We also provide consultation on regulatory strategy, product stewardship, portfolio management, and Task Force/Consortia management/representation and training.

Regulatory Strategy

  • Regulatory Advice under BPR – Legislation; Transitional arrangements; Requirements for products; Requirements for treated articles; Requirements for Biocidal Product Families (BPF); Technical Equivalence; Regulatory options
  • Product Stewardship – Assistance in promoting best practices through responsible manufacturing, communication and use of their products throughout Europe and globally
  • Portfolio Management - A client-tailored service. Examples of these types of project range from acting as a local agent to support national registrations to developing and managing strategies for compounds in various stages of their regulatory lifecycle. For national registrations, we provide regulatory strategy and support to ensure that the product portfolio is maintained at the desired level in terms of investment in the compound/product and geographic reach of the registrations

  • Assisting in the design of efficacy testing programmes including test protocols, using relevant guidance/methodologies (i.e. TNsG, EN, ASTM, OPPTS, OECD) to fulfil data requirements and data reporting standards
  • Preparing efficacy testing programme, (including advising on study placement, study monitoring, reviewing reports, assessing and collating data)
  • Providing expert assistance in drafting product labels
  • Assisting with new regulatory requirements e.g. comparative assessment
  • Providing training on all aspects of biocide efficacy

Exposure Modelling and Risk Assessments

Exponent has a vast amount of experience in tiered and refined human health and environmental risk assessments to support active substance and product authorisations. Our expertise enables us to ascertain when exposure scenarios may be unsuitable for a particular application and to present alternatives to regulators with confidence. We have expert knowledge of a wide range of environmental, operator, professional and consumer exposure models used around the world.

  • EUSES (EU System for the Evaluation of Substances)
  • Emission Scenario Documents (ESDs, e.g. EU-ESDs, OECD ESDs)
  • ConsExpo
  • BEAT (Bayesian Exposure Assessment Tool)
  • ECHA Guidance for Human Health Risk Assessment, TNsG’s, HEEG Opinions (MOTA)
  • WHO Generic Risk Assessment Model for Indoor and Outdoor Space Spraying of Insecticides
  • EASE (Estimation & Assessment of Substance Exposure)
  • POEM/EUROPOEM (Predictive Operator Exposure Model)
  • AOEM/EFSA model
  • RiskOfDerm
  • WPEM (Wall Paint Exposure Model)
  • Stoffenmanager
  • EFSA (European Food Safety Authority Multi-Diet Spreadsheet Model)
  • FOCUS (FOrum for Co-ordination of pesticide fate models and their USe) 
    • Surface Water: STEPS1-2, SWASH, MACRO, PRZM_SW, TOXSWA 
    • Groundwater: MACRO, PEARL, PELMO, PRZM_GW
  • MAMPEC (Marine Antifoulant Model to Predict Environmental Concentrations)

In situ Generated Biocides

Exponent has been at the forefront of discussions with ECHA, the EU Commission and Member States with regard to the methodology and interpretation of the regulations regarding in situ biocides, in particular where the precursors cannot be authorised. Having successfully achieved completeness for in situ active substance dossiers we are now working with the Member States to establish practical solutions to regulatory data requirements that make business sense, meet the requirements of the BPR and permit successful authorisation of in situ-generated products and biocidal product families. For active substances that are generated from precursors (other than ambient air or water) the information requirements of Annex II, Title 1 of the BPR apply to both the in situ generated active substance and the precursors (exact details on the extent of the data required can be found in the ECHA Guidance ). For in situ generated active substances, the biocidal product is considered to be either the precursors that generate the in situ active substance, or in situations where the precursors cannot be authorised (e.g. ambient air or water including seawater) the in situ generated active, such as ozone or active chlorine. Exponent can provide both technical and regulatory expertise to assist in the preparation of in situ generated active substance product dossiers.

Technical Equivalence (TE) Assessment

  • Preparation of Tier I and Tier II applications when there has been a change in manufacturing process or new source of the active substance

  • Addressing Competent Authorities’ queries
  • Attending ECHA Working Group (WG), Biocidal Products Committee (BPC) and Competent Authority (CA) meetings with or on behalf of clients

Global National Registration

Exponent has experience of biocide regulatory systems on a global scale. We can assist you with obtaining information about product notification or registration requirements and with regulatory submissions on a global basis.

  • Advice on national legislation
  • Data requirements for biocide product registration/notification
  • Liaison with regulatory authorities/local contacts

Task Force/Consortia Management

Exponent has many years’ experience in managing Task Forces/Consortia for biocides and is able to construct dossiers utilising data from different Task Force members whilst maintaining data confidentiality.


Exponent can provide training tailored to your specific needs. Training topics include:

  • Legislation awareness
  • Use of IT tools (IUCLID and R4BP)
  • Dossier compilation and submission

Complementary Service

Exponent also offers a service that is complementary to your in-house expertise which has the advantage of a "fresh pair of eyes" and/or "inside track" views from former regulators on the likely acceptability of proposed courses of action. These aspects include:

  • Peer reviewing documents
  • Acting as a sounding board on potential courses of action/strategies
  • Providing a "neutral viewpoint" to obtain views on particular issues from EU Regulatory Authorities without the need to disclose the compound of interest.
  • Tailored training
  • Provide organisational capacity within multi-disciplinary teams to address multiple projects
