What are azo dyes?

Azo dyes are a group of synthetic dyes characterized by the presence of the azo group (-N=N-) as part of their molecular structure, widely used for their vibrant colors and cost-effectiveness.

How do you ensure azo dyes are safe?

Look for azo dyes that are labeled non-toxic, ECOSafe, or REACH compliant. These certifications ensure the dyes adhere to safety standards and minimize harm to users and the environment.

Can azo dyes fade over time?

Yes, some azo dyes can fade if not properly fixed or exposed to extended sunlight or frequent washing. Using a dye fixative can help prolong the color’s life.
