NIAS Non Intentionally Added Substances

Smithers Pira can perform NIAS risk assessments and evaluate the hazard of the identified substances as included in Regulation EU 10/2011.

To ensure food and consumer safety, manufacturers of plastic food contact materials and articles are required to conduct migration studies following regulatory guidelines. There is also a requirement to carry out a safety evaluation for non-intentionally added substances (NIAS) if present.

What are Non Intentionally Added Substances – NIAS?

NIAS are chemical compounds that are present in a material but have not been added for a technical reason during the production process. Their presence in food contact materials is often challenging for food contact materials producers.

NIAS originate from break-down products of food contact materials, impurities of starting materials, unwanted side-products and various contaminants from recycling processes

These NIAS may arise in the finished materials and articles from impurities or degradation products of positively listed substances or residues from the polymerization process. NIAS can also arise from recycled content or treatment processes such as irradiation.

Expert support with NIAS risk assessments

Identification and measurement of NIAS is required for the safety evaluation, and this may require the use of sensitive and high resolution mass spectrometry coupled with GC or LC.

Regulation EU No. 10/2011 states that NIAS (non-intentionally added substances) that may be present in final articles, should be risk assessed using internationally recognized scientific principles. NIAS may be present as degradation products of authorized substances or as impurities in authorized substances.


How we can help:
Smithers Pira can help you with this risk assessment by measuring migration of NIAS into food/food simulants and evaluating the hazard of the identified substances.
