Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reactive Red 239 did not cause acute toxic effects after oral and dermal administration. The test substance is neither irritant to skin nor eyes, nor shows sensitizing effects. In the 28 days subacute and the 90 days subchronic toxicity studies in the rat, no treatment-related clinical signs and no signs of systemic toxicity were observed throughout the study. The administration of Reactive Red 239 resulted in a dose-dependent incorporation of the substance in the proximal tubule of the kidneys without causing changes in renal morphology or showing evidence of impaired renal function in the clinical chemistry parameters. Consequently, the 'no observed adverse effect level' (NOAEL) in these studies is  >= 1000 mg/kg bw/day.

Due to the chemical reaction of the dye with the cotton during the dyeing process, the test substance is covalently bound to the textile. It is therefore unlikely that the consumer is exposed to the dye from contact to the dyed textile. Hence no risk of dermal or inhalational exposure for consumers arises from the dye by use of the final product.


For consumer use ‘Home-Dyeing’ the dyeing procedure is limited to dyeing in a closed system (washing machine). Potential consumer exposure is minimised by the mode of application, use conditions (a washing machine is charged with the closed package) and safeguarded by the type of packaging (no opening/open handling of the dye preparation). The preparations for home-dyeing are either liquid formulations or ready-to-use solid preparations which do not allow exposure to the dye (e.g. sheath that is dissolved in the washing machine). Users from the general population are protected from any contact by the use of packaging that is not opened but directly charged into the washing machine when textiles are dyed at home. There is no open handling of the product. In addition, the use instructions provided with the textile dyes explicitly recommend the use of gloves and skirting for manual use of textile dyes. The consumers are anticipated to use at least gloves to avoid staining of the hands. No exposure is expected to occur during normal use and handling during home dyeing.
