Disperse Dyes Testing in Products

What is disperse dyes testing?

Disperse dyes testing identifies what types and levels of disperse dyes you may have in your products. Disperse Dyes are organic, water soluble dyes mainly used in the dyeing of polyester, nylon and acrylic fibres, and are widely used in the textile manufacturing.

BLC offers disperse dye testing at our UKAS accredited laboratory; we are one of the fastest testing laboratories in Europe and can provide test results within 3-5 working days. At BLC, we identify compounds that are likely to be present in materials tested, where they may originate and the likelihood of false positive results.

Risks of disperse dyes in products

The main risk associated with the use of disperse dyes in products in the potential to cause an allergic reaction when in contact with the skin. A number of disperse dyes have been identified as having properties to cause allergic skin reactions. There are also disperse dyes which are classified as carcinogenic.

Disperse dyes may be used in the manufacture of textiles for a range of end products, including:

  • Stockings
  • Socks
  • Trousers
  • Blouses
  • Lingerie
  • Gloves
  • Hats
  • Clothing for babies and children

One further issue with the use of disperse dyes, is that they do not demonstrate good fastness properties with all synthetic fabrics, and this may also cause problems relating both to quality and allergies.

Why test for disperse dyes?

If you are a retailer, importer, or manufacturer of clothing, accessories, textile products, or children’s toys, you need to have your products tested to identify any potentially harmful levels of disperse dyes.

A number of countries have regulations in regards to the use of disperse dyes under the food and commodity goods laws. Therefore, at BLC, we advise you to carry out the appropriate due diligence testing on your products before marketing and retailing your products.

Disperse dyes are also covered under the European standard BS EN 71 part 9:2005 Safety of Toys. This toy safety standard lists a number of disperse dye compounds that are prohibited for use in children’s toys.
