Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The Derived No-Effect Levels (DNEL) were calculated using the recommendations of the ECHA "Guidance on information requirements and chemical safety assessment – Chapter R.8: Characterisation of dose [concentration]-response for human health" (May 2008).

The adverse effects selected for DNEL derivation were considered to bear a threshold mode of action.

-      Acute toxicity:

In the absence of any relevant toxic effect and in particular any acute toxicity hazard leading to Classification & Labelling, no specific DNEL was derived.

-      Irritation/Corrosion:

In the absence of irritation effects related to the test substance, no specific DNEL was derived.

-      Sensitization:

In the absence of skin sensitization effects related to the test substance, no specific DNEL was derived.

-      Repeat-dose toxicity:

Dermal exposure:

The study selected for dermal DNEL derivation is the OECD 407 and OECD 421-compliant studies in rats where no significant systemic toxicity was observed up to the highest tested dose, i.e. 1000 mg/kg b. w. /day.

-      Dose descriptor: NOAEL = 1000 mg/kg bw in rats

-      Corrected dose descriptor: No correction was applied (dermal NOAEL = oral NOAEL because both oral and dermal absorptions are considered negligible)

-      Assessment factors:

Interspecies differences = 4 (default value for rats)

Other toxicokinetic differences = 2.5 (default value for rats)

Intraspecies differences = 5 (default value for workers)

Differences in exposure duration = 6 (default value for subacute to chronic exposure extrapolation)

Dose-response issues = 1 (use of a NOAEL as a starting point)

Quality of the database = 1 (complete and reliable data)

=> Global assessment factor = 300

-      DNEL calculation:

Worker-DNEL long-term for dermal route, systemic effects = 1000 / 300 = 3.3 mg/kg bw

Inhalation exposure:

Exposure of humans via inhalation is unlikely (very low vapour pressure); handling of the registered substance does not produce vapour, aerosols or droplets. Furthermore, the most probable route of exposure is the dermal route since the substance is produced and commercialized as a liquid.
