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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Appearance / physical state / colour
Administrative data
Link to relevant study record(s)
- Endpoint:
- appearance / physical state / colour
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Study period:
- Up to 2008
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: GLP status not known, guideline not known, information from a published handbook, acceptable with restrictions.
- Justification for type of information:
- A discussion and report on the read across strategy is given as an attachment in IUCLID Section 13.
- Reason / purpose for cross-reference:
- read-across: supporting information
- Principles of method if other than guideline:
- The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The introduction to the CRC Handbook of Chemistry and Physics states that data for physical constants have been taken from many sources, including both compilations and the primary literature. Where conflicts were found, the value deemed most reliable was chosen. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data.
- GLP compliance:
- not specified
- Physical state at 20°C and 1013 hPa:
- liquid
- Key result
- Colour:
- Colour 5. ISO6271-2
- Conclusions:
- The physical state of Normal-Hexane at room temperature is a liquid.
- Executive summary:
The physical state of Normal-Hexane has been taken from the CRC Handbook (Lide 2008). No information on the primary source of this data or the methods used is available. However, this information is taken from a reliable peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint.

Description of key information
There is appearance/physical state/colour data available for Hydrocarbons, C5 -C7, n-alkanes, isoalkanes, n-hexane rich. Additionally, data is available for n-hexane and isohexane and is presented based on analogue read across.
The physical state of the substance at room temperature is a liquid.
Key value for chemical safety assessment
- Physical state at 20°C and 1013 hPa:
- liquid
Additional information
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.
