Measured values for Glycerin, and where each one comes from
33 measured values for 12 properties, read from 4 public databases. On 4 properties the records differ. Each reading is shown with its own record. Follow any record to read the value at its source.
Boiling point
4 records agree
Used with vapour pressure to judge how readily the substance reaches the air you breathe.
- 290 °C (decomposes)
- Hazardous Substances Data Bank (HSDB)
- 554 °F (Decomposes)
- NIOSH Pocket Guide
- 554 °F (decomposes)
- OSHA Occupational Chemical Database
- 290 °C @760 [mm Hg]
- PAC Chemical Database, U.S. Department of Energy
Melting point
4 records agree
Fixes the physical state at handling temperature, which the label and the transport class depend on.
- 64 °F
- NIOSH Pocket Guide
Flash point
3 records, 160 to 177 °C
The lowest temperature at which the liquid gives off enough vapour to ignite. It decides the GHS flammable liquid category.
- 177 °C (Open cup)
- Hazardous Substances Data Bank (HSDB)
- 320 °F
- NIOSH Pocket Guide
Auto-ignition temperature
1 record
The temperature at which the substance ignites with no spark or flame. It sets safe surface and process temperatures.
Explosive limits
1 record
The vapour concentration range in air that will burn. Below the lower limit and above the upper limit it will not.
- Confined mixture with chlorine explodes if heated to 70 - 80 degree
- Hazardous Substances Data Bank (HSDB)
Vapour pressure
4 records differ
The higher it is, the faster the substance evaporates into the workplace air at room temperature.
- VP: 0.0025 MM HG AT 50 °C
- Hazardous Substances Data Bank (HSDB)
- 1.68X10-4 mm Hg at 25 °C
- Hazardous Substances Data Bank (HSDB)
- (122 °F): 0.003 mmHg
- NIOSH Pocket Guide
- 0.003 mmHg at 122 °F
- OSHA Occupational Chemical Database
Vapour density
2 records differ
Above 1 the vapour sinks and collects in pits, sumps and low enclosed spaces.
- 3.17 (Air = 1)
- Hazardous Substances Data Bank (HSDB)
Density
5 records differ
Needed to convert between mass and volume on the label, in transport papers and in a spill estimate.
- 1.2613 g/cu cm at 20 °C
- Hazardous Substances Data Bank (HSDB)
- A trihydric (polyhydric) alcohol; hygroscopic; density (anhydrous): 1.2653; density (USP): >1.249 at 25 °C/25 °C; density (dynamite): 1.2620

- 1.2613 @ 20°C
- PAC Chemical Database, U.S. Department of Energy
Solubility
5 records, each a different case
Determines spill behaviour, the right extinguishing media and the correct first-aid rinse.
- Miscible with ethanol; slightly soluble in ethyl ether; insoluble in benzene, carbon tetrachloride, chloroform, carbon disulfide, petroleum ether
- Hazardous Substances Data Bank (HSDB)
- SOLUBILITY IN ACETONE: 1 G IN 15 ML
- Hazardous Substances Data Bank (HSDB)
- Insoluble in fixed and volatile oils
- Hazardous Substances Data Bank (HSDB)
- In water, 5.296X10+6 mg/L at 25 °C
- Hazardous Substances Data Bank (HSDB)
- Miscible
- NIOSH Pocket Guide
Partition coefficient (log Kow)
1 record
Indicates whether the substance accumulates in fat or in water, which drives the environmental sections.
- log Kow = -1.76
- Hazardous Substances Data Bank (HSDB)
Viscosity
1 record
Governs how far a spill spreads and how fast it soaks into a surface or a sorbent.
- 954 CENTIPOISES AT 25 °C; 17 CENTIPOISES AT 25 °C (70% SOLN)
- 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.
These are the public records read for Glycerin, 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.
