Inert ingredients are routinely used in commercial crop protection formulations for purposes such as UV stabilizers, emulsifiers, solvents, carriers, and dyes.  The inerts and the crop protection products that they are formulated into will ultimately be applied to various crops and food commodities, so any residues of pesticides and inerts remaining behind need to be demonstrated as safe for human consumption.  While the regulatory approach for exposure and risk assessment of pesticides is well established and well understood, that is not true for inert ingredients.  The exact composition of crop protection formulations and the inert and active ingredients contained therein are strictly-held trade secrets by the manufacturers.  Commercially available inerts are often certified by their manufacturers as having been demonstrated as safe for use in foods or food products.  This presentation will offer a series of tiered exposure and safety assessment approaches for a generic inert ingredient that had not previously been demonstrated as safe for use in crop protection products that are suitable for use in regulatory inert assessment registration submissions.
