Bisphenol A diglycidyl ether (BADGE) assay

Why analyze the BADGE?

Bisphenol A diglycidyl ether (BADGE) is a derivative of bisphenol A (BPA) widely used in the formulation of epoxy resins, particularly for the inner coatings of food packaging, technical adhesives, and varnishes. Due to its potential to disrupt the endocrine system, its use in food contact materials is regulated under Regulation (EU) No 10/2011.

Measuring bisphenol A diglycidyl ether or BADGE is crucial for:

• Evaluate specific migrations towards food or simulators
• Verify compliance with regulatory limits (SML: 9 mg/kg)
• Ensuring consumer safety and packaging compliance

Analytical methods

The analysis is performed by LC-MS/MS or HPLC, after targeted extraction of the BADGE from the matrix (film, coating, adhesive).
The methods comply with the requirements of EC Regulation 1935/2004 and are validated according to ISO 17025.

Matrices analyzed

• Food packaging made from epoxy resin
• Interior varnish for cans or metal boxes
• Multilayer films or technical coatings
• Glues, adhesives or protective lacquers
