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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In a first step, the starting point oral value should be corrected forroute-to-route extrapolation. In accordance with REACH guidance document R.8 (‘Characterization of dose (concentration)-response for human health’), in the absence of data, no default factor (i.e. factor of 1) should be introduced for oral-to-dermal extrapolation, basedon the assumption that dermal absorption will in general not be higher than oral absorption.However, for highly lipophilic substances (log Kow > 4), according toSection R.7.12.2.1 of REACH guidance document R7.C (May 2008), a 10% default dermal absorption percentage value is recommended (in the absence of test data) for the purpose of risk assessment.Therefore a factor of 9.6 (ABSoral/ABSdermal= 96/10) can be used to correct the starting dose for absorption difference between routes.
The next steps consist in applying assessment factors (AF) for interpecies difference, intraspecies variation, exposure duration, dose-response and quality of the database, as presented in Section R.8.4.3 of REACH guidance document R.8. The overall AF in this case corresponds to 50.
The resulting DNELlong-term, workers, dermal is equivalent to 1,776 mg /kg bw/day.

For consumers, asimilar procedure is applied as for the derivation of worker DNELs. The only difference is that the assessment factor for intraspecies variation is 10 instead of 5 in this case, according to Section R.8.4.3 of REACH guidance document R.8. The overall AF therefore corresponds to 100.
The resulting DNELlong-term, consumers, dermal is equivalent to 888 mg /kg bw/day.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
