Quantitative scanning electron microscopy characterization to determine if microfibrillated cellulose is considered a nanomaterial in food, food-contact and cosmetic regulations

The proposed project will use microfibrillated cellulose (MFC) from the University of Maine Process Development Center (UMaine MFC) as a reference material to develop a robust dispersion, sample preparation, image capture, and image analysis methodology to determine whether it is considered a nanomaterial under different regulatory frameworks. The methodology will employ scanning electron microscopy (SEM), and once a detailed standard operating procedure (SOP) is established, we will apply the approach to evaluate whether five industrial forms of MFC from Canadian manufacturers meet nanomaterial regulatory definitions. This work will allow Vireo Advisors Canada to develop an SOP to determine if industrial cellulose materials meet the regulatory definition of a nanomaterial in a number of jurisdictions and in turn what regulatory requirements are needed for the approval of these materials in different sectors. This is an essential step required for safety demonstration and regulatory approval of MFC not only in Canada but also in the US, EU and other markets. In the longer term, Vireo can apply the methodology developed in this project to other Canadian clients’ products to facilitate regulatory approvals and commercial adoption in Canada and other countries. This project will help promote safer and more sustainable material entry into the marketplace and help keep Canada competitive globally.
