New manufacturers must complete a verification process to become accredited. The process consists of a meticulous questionnaire and thorough sampling of the material before approval.





Samples of new materials are obtained from suppliers and are thoroughly checked using a variety of methods including FTIR and external testing before they are approved.





The raw material questionnaire is a comprehensive assessment of the product with the aim of proving that what we’re buying from the supplier is the promised material. It also ensures that the product complies with legislation and includes questions of sourcing, processing, allergens, site information, possible contaminants, GMO and BSE/TSE status.
