Allergenic Disperse Dyes

WHAT ARE THEY?

They are a type of dye not ionic and insoluble in water used in the textile industry in dyeing and printing processes, basically in products made of acetate, polyester and polyamide.

TOXICOLOGY?

When they come into direct contact with the skin, these dyes may produce allergic reactions.

Disperse dyes are commonly used to dye polyester, also acetate and nylon. A small number of these dyestuffs have been identified as allergenic, causing severe skin irritation.

No EU legislation exists, but they are regulated by voluntary eco-testing schemes such as Oeko-tex and the EU Eco Label.
