Biocides Efficacy

Regulatory authorities throughout the globe require that efficacy claims for biocidal products be substantiated with suitable data. To obtain regulatory approvals, such efficacy data must be generated using methodologies acceptable to the applicable competent authorities and demonstrate a level of performance that adequately supports the desired claims. In many cases, specific regulatory and scientific expertise is crucial to identifying the relevant efficacy data requirements and navigating those requirements and their associated complexities in an effective and efficient manner.

Exponent has experts adept at identifying the efficacy data requirements for different biocidal products, according to different regulations, and designing, reviewing, monitoring, and evaluating studies that meet those requirements. We routinely engage with competent authorities to develop new testing methodologies or adapt existing ones to suit novel products and technologies. Exponent’s experts are proficient with a wide variety of different biocidal product types including antimicrobial pesticides, conventional agricultural pesticides, biopesticides, insecticides and acaricides, rodenticides, repellents and attractants, molluscicides, preservatives, antifouling products, treated articles, etc. We can work in a tailored manner, seamlessly as part of your team, providing specific high-quality expertise not available in-house, or provide additional resources at times of work overload.

Exponent’s regulatory and scientific experts can provide strategic efficacy testing advice and help evaluate product portfolios and intended claims to streamline testing and increase speed to market. These experts have extensive experience helping our clients meet the applicable regulatory requirements in multiple geographies including the US, EU, UK, and Asia. Exponent’s staff include individuals with prior experience in industry, government, and academia, and this diversity of experience allows Exponent to approach regulatory matters from different points of view and go one step further in identifying solutions and paths forward.
