Azo free dyes are low impact dyes that eliminate the use of toxic compounds. These types of dyes are not only better for the health of consumers than conventional dyes, but they are also eco-friendly and sustainable. This is why Ivy Marie products are dyed at a GOTS certified unit using low impact azo free dyes.
So, What Exactly Are Azo Dyes?
Azo dyes consist of chemicals and synthetics and are commonly used to color a range of products including plastics, cosmetics, textiles, food and more. Azo dyes can color fabric without the need for a mordant (a substance that fixes a dye to a fabric). While this may be convenient – and the main reason why 70% of textile commercials use these dyes – azo dyes can be harmful to the environment and to the health of consumers.
What Are The Benefits of Azo Free Dyeing?
- Azo free dyes do not use heavy metals or harmful and toxic chemicals, making them better for both the environment and consumers’ skin.
- Some azo dyes break down during use and release carcinogenic and aromatic amines, which can cause cancer. Azo free dyes do not consist of nitrogen-based compounds so they do not liberate amines.
- Azo free dyes have a higher absorption rate, allowing for less water wastage into the environment. Azo dyes, on the other hand, have been found to be resistant to waste water treatment, which means they can pass into the environment easily and relatively unchanged.
