Sections 1.3 and 1.4 are withheld here because the supplier and emergency contact blocks carry your own company details in the draft you buy. Every draft needs review by a competent person before it is issued.
Measured values for Limonene, and where each one comes from
15 measured values for 10 properties, read from 2 public databases. On 3 properties the records differ. Each reading is shown with its own record. Follow any record to read the value at its source.
Boiling point
1 record
Used with vapour pressure to judge how readily the substance reaches the air you breathe.
Melting point
2 records, -95 to -40 °C
Fixes the physical state at handling temperature, which the label and the transport class depend on.
Flash point
2 records, 45 to 46 °C
The lowest temperature at which the liquid gives off enough vapour to ignite. It decides the GHS flammable liquid category.
- 113 °F (45 °C) (Close cup)
- Hazardous Substances Data Bank (HSDB)
Auto-ignition temperature
1 record
The temperature at which the substance ignites with no spark or flame. It sets safe surface and process temperatures.
- 458 °F (237 °C)
- Hazardous Substances Data Bank (HSDB)
Vapour pressure
1 record
The higher it is, the faster the substance evaporates into the workplace air at room temperature.
- 1.55 mm Hg at 25 °C /extrapolated/
- Hazardous Substances Data Bank (HSDB)
Vapour density
1 record
Above 1 the vapour sinks and collects in pits, sumps and low enclosed spaces.
- 4.7 (Air = 1)
- Hazardous Substances Data Bank (HSDB)
Density
2 records differ
Needed to convert between mass and volume on the label, in transport papers and in a spill estimate.
- 0.8402 at 20.85 °C/4 °C
- Hazardous Substances Data Bank (HSDB)
- 0.842 at 69.8 °F
- OSHA Occupational Chemical Database
Solubility
3 records, each a different case
Determines spill behaviour, the right extinguishing media and the correct first-aid rinse.
- In water, 7.57 mg/L at 25 °C
- Hazardous Substances Data Bank (HSDB)
- Miscible with alcohol
- Hazardous Substances Data Bank (HSDB)
- Miscible with alcohol, ether
- Hazardous Substances Data Bank (HSDB)
Partition coefficient (log Kow)
1 record
Indicates whether the substance accumulates in fat or in water, which drives the environmental sections.
- log Kow = 4.57
- Hazardous Substances Data Bank (HSDB)
Odour
1 record
Odour is a warning property only. Many substances are hazardous well below the concentration you can smell.
- Pleasant lemon-like
- Hazardous Substances Data Bank (HSDB)
These are the public records read for Limonene, published here unchanged. Where two records disagree, the draft you buy states the value and names the record behind it, so a reviewer can see what was chosen. Every draft needs review by a competent person before it is issued.
