Assessment of whether the level of NP migrating from FCMs should be of concern has not reached a consensus in regulatory agencies, partly because NP is predominantly present as an impurity or degradation product as a NIAS. The U.S. Food and Drug Administration (FDA) includes nonylphenol, nonylphenol,p—, octylphenol, octylphenol,p—, and tris(nonylphenyl)phosphite (see Table 5.1) in their List of Indirect Additives Used in Food Contact Substances (FDA 2014), but NP and OP are not approved by the FDA for use as direct food additives. Neither NP nor OP are listed in FDA s Cumulative Estimated Daily Intake database for food contact substances (FDA 2013).
