Azo Dyestuff Determination in Imitation Jewelry: A Critical Test for Safety and Compliance
Although imitation jewelry is often preferred for its fashionable appearance, certain chemical substances used in its production process can pose risks to human health. One such group of chemicals is azo dyes, which can lead to the release of aromatic amines—potentially carcinogenic compounds—due to prolonged contact or interaction with bodily fluids. As part of its imitation jewelry analysis services, TAREKS analysis laboratory offers azo dyestuff determination, ensuring product compliance with KKDİK regulations and other international standards.
What Are Azo Dyes and Why Must They Be Tested?
Azo dyes are a common group of chemicals used in textiles, leather, and metal coatings. They are frequently chosen for accessories and imitation jewelry to provide colorfastness. However, these substances carry certain risks:
- Toxic and Carcinogenic Effects: Their breakdown can produce aromatic amines, which may be carcinogenic.
- Skin Contact Risks: They can cause irritation or allergic reactions, especially in sensitive skin.
These risks are regulated by the KKDİK regulation and the EU Azo Dye Directive (2002/61/EC) to protect consumers and the environment.
The Azo Dyestuff Determination Process
TAREKS analysis laboratory follows test procedures aligned with international standards for detecting azo dyes:
-
Sample Preparation
- Jewelry and accessories (such as watch straps, necklaces, and bracelets) are prepared for analysis, taking into account surface coatings and textile content.
-
Chemical Extraction
- Using special solutions, dyes are isolated from the product so that any azo compounds present can be thoroughly examined.
-
Detection of Aromatic Amines
- Samples are analyzed for aromatic amine release using HPLC (High-Performance Liquid Chromatography) or similar high-precision instruments.
-
Evaluation of Results
- Analysis findings are compared with KKDİK and EU Azo Dye Directive limits to determine whether the product is compliant.
Products Eligible for Testing
- Metal-Coated Jewelry: Rings, bracelets, necklaces, earrings, and similar items
- Watch Straps: Including those made of textile or leather
- Clasps and Accessories: Belt buckles, hair accessories, and other items in direct contact with the skin
Advantages of the Azo Dye Test
- Prevents Health Risks: Eliminates potential toxic effects caused by skin contact or inhalation.
