Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2008
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Test performed by the departament of chemistry , University of Tennessee
- Principles of method if other than guideline:
- A software approach to estimate called EPIWIN sponsored by the EPA has been used in the past for calculing vapor pressure for analogous molecules.
- GLP compliance:
- no
- Type of method:
- other: trend analysis.
- Specific details on test material used for the study:
- This substance is SugaNate 160NC, a composition very similar to 100NC, the main difference being only in the carbon chain length of the alkyl glycoside. SugaNate 160NC is C10-C16 alkyl glycoside and SugaNate 100NC is C8-C10 alkyl glycoside. The rest of the structure is identical. It is considered to be a very good surrogate substance for read-across.
- Temp.:
- 25 °C
- Vapour pressure:
- ca. 0 mm Hg
- Remarks on result:
- other: extremelly small vapor pressure
- Conclusions:
- Extremely low vapor pressure, estimated at ca 2 x10-18 by EPIWIN software for the active molecule.
This substance is produced and marketed as a 40% active solution in water and hence the VP of the SugaNate 100NC as sold is essentially that of water.

Description of key information
Extremely low vapor pressure, estimated at ca. 2 x10-18 by EPIWIN software for the active molecule.
This substance is produced and marketed as a 40% active solution in water and hence the VP of the SugaNate 100NC as sold is essentially that of water.
Key value for chemical safety assessment
- Vapour pressure:
- 23.76 kPa
- at the temperature of:
- 25 °C
Additional information
The vapor pressure of 100% water at 25 °C is 23.76 mm Hg. For the solution that contains 60% water, 37% Suga®Nate 160, and 3% NaCl the vapor pressure can be calculated from Raoult’s law:
The vapor pressure of an ideal solution is dependent on the vapor pressure of each chemical component and the mole fraction of the component present in the solution
For Suga®Nate 160, 37 g active Suga®Nate 160(MW 617.8 g/mol) = 0.0599 mol, 3 g NaCl (MW 58.44 g/mol) = 0.0513 mol, while 60 g water (18 g/mol) = 3.333 mol.
The mole fraction of water is thus: 3.333 / (3.333 + 0.0513 + 0.0599) = 96.8%
The partial pressure of water is thus 0.968 * 23.76 = 23.0 mm Hg.
Both Suga®Nate 160 and NaCl are salts, and have no appreciable vapor pressure, so the vapor pressure of the mixture is 23.0 mm Hg.
This will also be true of SugaNate 100NC applying the same logic
