Henry's Law constant
Administrative data
- Endpoint:
- Henry's law constant
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other:
- Remarks:
- Accepted, well-documented calculation method. Result is related to phenol, styrenated as measured values of vapour pressure and water solubility for the technical product of phenol, styrenated were used in the calculation of HLC. Molecular weight was derived as mean from the molecular weigths of the components and the quantitative composition in the technical product.
- Justification for type of information:
- 1. SOFTWARE
US EPA (2012). Estimation Programs Interface Suite™ (EPI Suite) for Microsoft® Windows, v 4.11. United States Environmental Protection Agency, Washington, DC, USA
2. MODEL (incl. version number)
Model HENRYWIN, version 3.20
3. SMILES OR OTHER IDENTIFIERS USED AS INPUT FOR THE MODEL
Not applicable (multi-constituent substance)
4. SCIENTIFIC VALIDITY OF THE (Q)SAR MODEL
- Defined endpoint: yes, HLC
- Unambiguous algorithm: yes (VP / WSol x MW)
- Mechanistic interpretation: input parameters are indicative for the distribution of a substance in air and in water.
5. APPLICABILITY DOMAIN
- Descriptor domain: not applicable
- Structural and mechanistic domains: not applicable
- Similarity with analogues in the training set: not applicable
6. ADEQUACY OF THE RESULT
Calculation result is based on measured data of the substance phenol, styrenated. It is considered to characterise satisfactorily the partitioning of the substance between air and water.

Materials and methods
- Principles of method if other than guideline:
- - Software tool(s) used including version: US EPA (2012). Estimation Programs Interface Suite™ (EPI Suite) for Microsoft® Windows, v 4.11. United States Environmental Protection Agency, Washington, DC, USA.
- Model(s) used: Model HENRYWIN, version 3.20
- Model description: HENRYWIN estimates Henry's Law Constant (HLC) by two separate methods that yield two separate estimates. The first method is the Bond Contribution Method and the second is the Group Contribution Method. For both methods, the chemical structure of the substance has to be know (i.e. SMILES notation). The Bond Method is able to estimate many more types of structures than the Group Method, because it has a more extensive library of bond contribution values.
In addition, HLC can be calculated with a simple method based on phys.-chem. data of a substance using the equation VP / WSol x MW. As phenol, styrenated is a multi-constituent substance, this method was used to estimate HLC applying measured values of VP and WSol and an average molecular weight.
- Justification of QSAR prediction: Estimates of HLC are widely used and are considered to be sufficiently accurate. The equation presented above correlates parameters indicative for the concentration distribution of a substance in air and in water.

Results and discussion
Henry's Law constant H
- Key result
- H:
- 0.036 Pa m³/mol
- Temp.:
- 20 °C
- Remarks on result:
- other: HLC was calculated by the equation HLC = VP / WSol * MW using the data determined for phenol, styrenated (LS 500)
Any other information on results incl. tables
HLC can be calculated using genuine data of a substance (vapour pressure / water solubility x molecular weight). For phenol, styrenated the values 0.0049 Pa , 31.8 mg/L, and 233 g/mol were used. Physical chemical data have been measured with phenol, styrenated (see Section 4) and a molecular weight was determined based on the moledular weigth and the percentage of the different constituents (mono and distyrenated phenols) of phenol, styrenated.
HLC = VP / WSol x MW = 0.0049 Pa / 31.8 mg/L x 236
HLC = 0.0364 Pa m³/mol
