What toxic chemicals are hidden in fast-fashion denim?

This could be a whole essay. But, to summarise, some of the toxic chemicals that may be hidden in fast-fashion denim include:

  1. Azo dyes: Azo dyes are synthetic dyes that are commonly used to color denim. Some azo dyes have been found to be carcinogenic and may cause allergic reactions.
  2. Formaldehyde: Formaldehyde is used in the finishing process to give denim a wrinkle-free appearance. Formaldehyde is a known carcinogen and can cause skin irritation and respiratory problems.
  3. Phthalates: Phthalates are plasticizers that are added to denim to make it softer and more flexible. Phthalates have been linked to hormone disruption, reproductive problems, and developmental issues.
  4. Heavy metals: Heavy metals such as cadmium, lead, and mercury may be present in denim production processes, particularly in the dyeing process. Exposure to heavy metals can lead to health problems such as cancer, kidney damage, and nervous system damage.
  5. Chlorine bleach: Chlorine bleach is sometimes used to achieve a distressed or worn look in denim. Chlorine bleach is a toxic substance that can irritate the skin and eyes, and may release harmful gases when mixed with other chemicals.

Lucky for us, there are plenty of amazing ethical denim brands that refuse to use any of the toxic chemicals listed above. Let’s jump right in!

This post is about the best sustainable denim brands.
