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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Link to relevant study record(s)
- Endpoint:
- self-heating substances / mixtures
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance is a liquid
- Endpoint:
- pyrophoric liquids
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied
- Endpoint:
- substances / mixtures which in contact with water emit flammable gases
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water
- Endpoint:
- flammable solids
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is a liquid

Description of key information

not self-heating
Key value for chemical safety assessment
- Flammability:
- flammable
Additional information
Flammability of methanol:
Based on the measured flash point of 9.7 °C and the boiling point of 65 °C, methanol is highly flammable. Based on the chemical structure and experience in handling and use, pyrophoricity and flammability in contact with water are not expected.
Flammability of the parent substance:
There are no measured data for the flammability of the parent substance, but since it is comprised of ca. 40% w/w silane and ca. 60% w/w methanol, the flash point is expected to be similar to that of neat methanol. Therefore the parent substance is expected to be highly flammable.
Based on the chemical structure and experience in handling and use, pyrophoricity and flammability in contact with water are not expected.
Self-heating: the substance is a liquid and a liquid does not demonstrate self-heating purposes, unless it is absorbed on a large surface.
Justification for classification or non-classification
The available data on the flash point and the boiling point of the test substance meet the criteria for classification as highly flammable liquid cat. 2 (H225) according to Regulation (EC) 1272/2008.
The available data on pyrophoricity and flammbility in contact with water of the test substance do not meet the criteria for classification and are therefore conclusive but not sufficient for classification: Based on the chemical structure and experience in handling and use pyrophoricity and flammability in contact with water are not expected.
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.
