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 Vanillin, and where each one comes from
12 measured values for 9 properties, read from 1 public database. Every record agrees. 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
1 record
Fixes the physical state at handling temperature, which the label and the transport class depend on.
Flash point
1 record
The lowest temperature at which the liquid gives off enough vapour to ignite. It decides the GHS flammable liquid category.
- 153 °C (307 °F) - closed cup
- 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.
- 1.18X10-4 mm Hg at 25 °C
- Hazardous Substances Data Bank (HSDB)
Vapour density
1 record
Above 1 the vapour sinks and collects in pits, sumps and low enclosed spaces.
- 5.2 (Air = 1)
- Hazardous Substances Data Bank (HSDB)
Density
1 record
Needed to convert between mass and volume on the label, in transport papers and in a spill estimate.
Solubility
3 records, each a different case
Determines spill behaviour, the right extinguishing media and the correct first-aid rinse.
- In water, 1.102X10+4 mg/L at 25 °C
- Hazardous Substances Data Bank (HSDB)
- Soluble in 125 parts water, 20 parts glycerin, 2 parts 95% alcohol, chloroform, ether
- Hazardous Substances Data Bank (HSDB)
- Very soluble in ethanol, diethyl ether, acetone; soluble in benzene, ligroin
- 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 = 1.37
- Hazardous Substances Data Bank (HSDB)
Odour
2 records, each a different case
Odour is a warning property only. Many substances are hazardous well below the concentration you can smell.
- Sweetish smell
- Hazardous Substances Data Bank (HSDB)
- Pleasant aromatic vanilla odor
- Hazardous Substances Data Bank (HSDB)
These are the public records read for Vanillin, 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.
