Primary Aromatic Amine Testing

Primary aromatic amines, also known as aromatic primary amines and abbreviated as PAAs, are important chemical intermediates and raw materials. They can be used to produce a series of industrial products, including pesticides, textiles, azo pigments, pharmaceuticals, cosmetics, rubber, aromatic polyurethane materials, etc. However, due to incomplete reactions or as impurities, by - products, or degradation products, they may migrate into the environment or food, causing food safety or environmental problems.

Service Background

Sources of Hazards of Primary Aromatic Amines

1.Main Sources of Primary Aromatic Amines in Food - Contact Materials and Articles

1.1 Some substances or additives containing aromatic amine groups are used in the production of plastic raw materials

1.2 Some cross-linking agents and chain extenders used in the plastic synthesis process may also release aromatic amine substances under certain conditions

2. Main Sources of Primary Aromatic Amines in Adhesives

For adhesives used in food and drug flexible packaging, primary aromatic amine substances are not intentionally added to the adhesive itself. They are non - intentionally added substances and are intermediates produced by side reactions during the use of aromatic polyurethane adhesives.

Service Items

II. Applicable Objects

Manufacturers, brand owners, and exporters.

III. Testing Requirements

1. The EU was the first region to pay attention to the migration of primary aromatic amines in food - contact materials.
