NOGE dosage

NOGE (Nonylphenol Glycidyl Ether) is an organic compound widely used as a reagent or plasticizer in epoxy resins and industrial formulations. However, due to its potential endocrine-disrupting properties and toxicity, it is classified as a hazardous substance and is subject to particular scrutiny under European regulations.

In materials intended for food contact (MCDA), the presence of NOGE is strictly regulated. Its measurement is therefore essential to verify material conformity and ensure consumer safety.

Analytical methods:
NOGE analysis relies on high-precision chromatographic techniques:

• LC-MS/MS (liquid chromatography coupled with mass spectrometry) for sensitive detection in complex matrices.
• GC-MS for quantification in volatile or semi-volatile formulations.
• GC-FID for routine analyses allowing for rapid follow-up.

These approaches are chosen according to the matrix (resin, glue, coating, ink) and sensitivity requirements.

Matrices concerned:
NOGE analysis can be performed in various industrial matrices:

• Epoxy resins and their formulations
• Protective coatings applied to metal or plastic packaging
• Glues and adhesives used in packaging manufacturing
• Inks and varnishes used in printing on food products
• Recycled materials that may contain residual traces of NOGE

Industrial applications

• Regulatory control : demonstrate the conformity of materials with Regulation (EU) No 10/2011, which prohibits the use of NOGE as a monomer or additive in food contact plastics.
• Consumer safety : preventing the migration of toxic substances into food.
• Material quality : ensuring safe and stable formulations for packaging, inks or coatings.
• Environmental monitoring : assess the possible presence of NOGE in recycled materials and limit the risks of recontamination.

Additional analyses:
NOGE measurement can be combined with other analyses for a complete evaluation of the materials:

• Determination of BADGE and derivatives (Bisphenol A diglycidyl ether), often used in the same epoxy resins.
• Dosage of BFDGE , another glycidyl derivative regulated by law.
• Measurement of NIAS , substances not intentionally added but generated by degradation or migration.
• Specific migration tests to verify the potential transfer of hazardous compounds into foodstuffs.

Regulations and Quality Issues
: Regulation (EU) No 10/2011 explicitly prohibits the use of NOGE as a monomer or additive in food contact plastics. Furthermore, the REACH Directive imposes reporting and assessment obligations for potentially hazardous substances, including NOGE.

Analytical testing is therefore a prerequisite for any company producing or using epoxy resins, coatings, or inks intended to come into contact with food. Failure to control this parameter exposes companies to risks of regulatory non-compliance, market withdrawal, and loss of consumer confidence.

YesWeLab's expertise:
YesWeLab collaborates with a network of partner laboratories specializing in the analysis of materials and polymers, accredited to ISO 17025 and, in some cases, recognized by COFRAC. Each sample is directed to the most suitable method and laboratory based on the matrix and the required sensitivity.

Thanks to our digital platform, we simplify the management of analyses: quote requests, online tracking, and centralized results. Since 2020, YesWeLab has been supporting manufacturers, distributors, and engineering firms in bringing their materials and packaging into compliance.
