Efsa publishes opinion on zinc oxide nanoparticles

The European Food Standards Agency (Efsa) has released is opinion on a new material.

The application was made to use zinc oxide, nanoparticles, uncoated and coated with [3-(methacryloxy)propyl] trimethoxysilane as a transparent ultraviolet light absorber in all polyolefins.

Considering the application, Efsa’s Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF) concludes that the nanoform of the material does not migrate at a dangerous level. The level of migration of soluble ionic zinc is also below the prescribed specific migration limits (SML). It is high enough, however, for CEF to conclude that the 25mg/person per day threshold might be exceeded once it is combined with other dietary exposure.

In the conclusion to its opinion issued on 13 April CEF recommends ‘that the commission reconsiders the SML of 25mg/kg for zinc, taking into account the fact that consumers are exposed to zinc from sources other than food contact materials.’
