More about regulatory risk assessment

Assessing the risks to human health or the environment of any chemical product is an essential part of the regulatory registration process. Preparing a detailed and thorough dossier of evidence and data is essential for a hassle-free product approval. We can help to ensure that you provide all the necessary evidence, compliance data and risk assessments to satisfy the requirements of the regulatory authority – whether for BPR or REACH registration.
