Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Flammability
Administrative data
- Endpoint:
- flammable liquids: obsolete as covered by section 'Flash point'
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance is a liquid
Cross-reference
- Reason / purpose for cross-reference:
- data waiving: supporting information
Reference
- Flash point at 101 325 Pa:
- 26 °C
The study was performed according to EU Method A.9, OPPTS 830.6315 and UN Manual Test Methods 32.4 under GLP-conditions.
First, a safety test was performed: approx. 3 mL of the test item was heated with a Bunsen burner up to the temperature of 140.1 °C. The appearance had not changed after cooling down.
Then, a pre-test and a main test with two experiments were performed using a flash point tester.
The flash point of the test substance is stated as 26.0 ± 0.5 °C (corresponding to 299.2 ± 0.5K). This value is the mean value of two independent determinations.
Flash point of hexanal was described in several handbooks/puplications. Described properties are nearly the same: hexanal has a flash point of about 32 °C. This fits with the experimental determined value and leads to the same classification.
CRC Handbook:
Hexanal has a flash point of 32.0 °C
Sax Dang. Prop.:
Hexanal has a flash point of 32.2 °C.
Lange Phys. const/prop.:
Hexanal has a flash point of 32.2 °C.

Applicant's summary and conclusion
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.
