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 Citric acid, and where each one comes from
12 measured values for 9 properties, read from 1 public database. On 1 property the records differ. Each reading is shown with its own record. Follow any record to read the value at its source.
Melting point
1 record
Fixes the physical state at handling temperature, which the label and the transport class depend on.
Auto-ignition temperature
1 record
The temperature at which the substance ignites with no spark or flame. It sets safe surface and process temperatures.
- 1850 °F (POWDER)
- Hazardous Substances Data Bank (HSDB)
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.
- Explosive limits, vol% in air: 0.28-2.29
- Hazardous Substances Data Bank (HSDB)
Density
3 records differ
Needed to convert between mass and volume on the label, in transport papers and in a spill estimate.
- 1.665 g/cu cm at 20 °C
- Hazardous Substances Data Bank (HSDB)
- BULK DENSITY: 56.2 LB/CU FT; HEAT OF SOLN: -3.9 KCAL/MOLE; BUFFERING INDEX: 2.46; STD FREE ENERGY OF ANION FORMATION: -278.8 KCAL FOR AQ SOLN @ 25 °C
- Hazardous Substances Data Bank (HSDB)
- Density: 1.542 g/cu cm /Citric acid monohydrate/
- Hazardous Substances Data Bank (HSDB)
Solubility
2 records, each a different case
Determines spill behaviour, the right extinguishing media and the correct first-aid rinse.
- In water, 3.83X10+5 mg/L at 25 °C
- Hazardous Substances Data Bank (HSDB)
- Very soluble in ethanol; soluble in ether, ethyl acetate; insoluble in benzene, chloroform
- 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 = -1.64
- 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.
- 2.549 cP 30% aqueous solution at 20 °C
- 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.
Decomposition temperature
1 record
The temperature at which the substance breaks down, often into products more hazardous than itself.
- Decomposes at 175 °C
- Hazardous Substances Data Bank (HSDB)
These are the public records read for Citric acid, 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.
