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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.
Use of this information is subject to copyright laws and may require the permission of the owner of the information, as described in the ECHA Legal Notice.
EC number: 232-350-7 | CAS number: 8006-64-2 Any of the volatile predominately terpenic fractions or distillates resulting from the solvent extraction of, gum collection from, or pulping of softwoods. Composed primarily of the C10H16 terpene hydrocarbons: α-pinene, β-pinene, limonene, 3-carene, camphene. May contain other acyclic, monocyclic, or bicyclic terpenes, oxygenated terpenes, and anethole. Exact composition varies with refining methods and the age, location, and species of the softwood source.

General Population - Hazard via inhalation route
Systemic effects
Long term exposure
- Hazard assessment conclusion:
- DNEL (Derived No Effect Level)
- Value:
- 0.018 mg/m³
- Most sensitive endpoint:
- repeated dose toxicity
- Route of original study:
- By inhalation
DNEL related information
- DNEL derivation method:
- ECHA REACH Guidance
- Overall assessment factor (AF):
- 50
- Dose descriptor starting point:
- NOAEC
- Value:
- 5 mg/m³
- Modified dose descriptor starting point:
- NOAEC
- Value:
- 0.89 mg/m³
- Explanation for the modification of the dose descriptor starting point:
The DNEL for systemic effects via the inhalation route for Block 4 is determined from the inhalation NOAEC for dimethylsulfide (5 mg/m³) from the 6-month study in rats.
The following corrections were made to the starting point:
Correction for exposure duration: (6 h/d to 24 h/d) (ECHA default)
Correction for dosing frequency: 5 days/7 days (ECHA default)
Therefore the corrected NOAEC for repeated-dose systemic effects via the inhalation route is:
5*(6/24)*5/7 = 0.89
- AF for dose response relationship:
- 1
- AF for differences in duration of exposure:
- 2
- Justification:
- Default (subchronic to chronic)
- AF for interspecies differences (allometric scaling):
- 1
- Justification:
- Default (rat inhalation to human inhalation)
- AF for other interspecies differences:
- 2.5
- Justification:
- Default
- AF for intraspecies differences:
- 10
- Justification:
- Default (general population)
- AF for the quality of the whole database:
- 1
- AF for remaining uncertainties:
- 1
- Justification:
- Default

- Overall assessment factor (AF):
- 200
- Dose descriptor starting point:
- NOAEL
- Value:
- 250 mg/kg bw/day
- Explanation for the modification of the dose descriptor starting point:
The DNEL for systemic effects via the oral route is determined from the oral NOAEL for dimethyl sulfide (250 mg/kg bw/day) from the 90-day study in rats. No correction of the starting point is needed.
