At The Sox Factory, we make custom socks that are safe, durable, and responsibly produced. We are proud to announce that we are now AZO-free certified.
This certification confirms that our socks are made without harmful AZO dyes. It supports our commitment to health, safety, and sustainability.
Below, we explain what AZO dyes are, why they matter, and what this certification means for you.
What Are AZO Dyes?
AZO dyes are synthetic dyes commonly used in the textile industry. They are popular because they create bright colours and last a long time.
However, some AZO dyes are harmful.
When certain AZO dyes break down, they can release chemicals called aromatic amines. These chemicals can be absorbed through the skin.
This is more likely during exercise or long wear.
Why Are AZO Dyes Harmful?
Some aromatic amines are known to be carcinogenic.
They have been linked to:
- Skin irritation
- Allergic reactions
- Serious health risks, including bladder cancer
AZO dyes also harm the environment. They often enter wastewater systems and pollute rivers and oceans. This affects aquatic life and water quality.
Choosing AZO-free dyes reduces these risks.
