Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Description of key information
No lethality was observed by either route. All animals survived, gained body weight, and appeared active and healthy during the study. There were no signs of gross toxicity, adverse clinical signs, or abnormal behavior. No gross abnormalities were noted for the animals when necropsied at the conclusion of the 14-day observation periods.
Key value for chemical safety assessment
Acute toxicity: via oral route
Endpoint conclusion
- Dose descriptor:
- LD50
- Value:
- 2 000 mg/kg bw
Acute toxicity: via dermal route
Endpoint conclusion
- Dose descriptor:
- LD50
- Value:
- 2 000 mg/kg bw
Additional information
The acute oral and dermal LD50 value for Natural oil monomer (Methyl Polyhydroxymethyl Stearate) is > 2000 mg/kg. Due to the low vapour pressure of NOM, the acute inhalation toxicity study was not conducted. As the acute oral and dermal LD50 values are greater than 2000 mg/kg (limit test doses), Natural Oil Monomer does not merit classification based on acute toxicity.
Justification for classification or non-classification
As the acute oral and dermal LD50 values are greater than 2000 mg/kg ( limit test doses), Natural Oil Monomer does not merit classification based on acute toxicity.
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.
