EFSA | Safety assessment of the substance silver nanoparticles for use in food contact materials

The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the additive silver nanoparticles intended to be used in plastics. All the silver particles are in the size range of 1–100 nm, with about 15 nm mean diameter and 99% by number of particles below 20 nm. The additive is intended to be used as a surface biocide at up to 0.025% w/w in non‐polar plastics for contact with a wide variety of foods, times, temperatures and food contact surface/mass of food ratios.
