Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Additional information

Waste water from 25 representative rubber manufacturing sites in Europe (France, Germany, Italy, Poland, Spain, UK), including tyre and general rubber goods manufacturing, were sampled and analysed for 6PPD and the hydrolysis product 4-hydroxydiphenylamine (4-HDPA). Additional information was collected from individual sites, mainly on tonnages, waste water flow and relevant production conditions.

The total emission of the test substance to waste water could be measured to reach a value of 5.61 kg/year (90th percentile). Inserting this data into the estimation program EUSES the following result was determined:

Safe use can be demonstrated for a site with a waste water load of 6PPD of up to 3.5 kg/year, emitting to a standard sewage treatment plant (10,000 inhabitants) and to a standard river (20,000 m3/day).

Statistical evaluation showed that with regard to local concentrations in receiving rivers and the concentration in agricultural soils, safe use is established using the 90thpercentile of the rubber manufacturing sites.
