Viscosity
Administrative data
Link to relevant study record(s)
- Endpoint:
- viscosity
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
- Justification for type of information:
- 1. SOFTWARE
US EPA T.E.S.T. version 5.1
2. MODEL
Viscosity at 25 °C
3. SMILES OR OTHER IDENTIFIERS USED AS INPUT FOR THE MODEL
See “Test material information”
4. SCIENTIFIC VALIDITY OF THE (Q)SAR MODEL
See attached information on the model, extracted from the official documentation provided by the developer. Further information on the OECD criteria as outlined by the applicant is provided below under "Any other information of materials and methods incl. tables"
5. APPLICABILITY DOMAIN
See attached information and information as provided in "Any other information on results incl. tables".
6. ADEQUACY OF THE RESULT
See assessment of adequacy as outlined in the "Overall remarks, attachments" section. - Qualifier:
- according to guideline
- Guideline:
- other: REACH Guidance on QSARs R.6
- Principles of method if other than guideline:
- Calculation based on T.E.S.T. version v5.1, consensus method
- Software tool(s) used including version: T.E.S.T. v5.1
- Model(s) used: Viscosity at 25 °C
The model is a consensus result of five independent models built using different approaches: Hierarchical Clustering, Single Model, FDA Method, Group contribution method, and Nearest neighbor method. For the complete methods' descriptions see field 'Justification for type of information / Attached justification'.
The dataset used for the model development and for the external validation is derived from "Data Book on the Viscosity of Liquids" (Viswanath et al., Hemisphere Pub. Co., 1989) and "Organic Solvents Physical Properties and Methods of Purification, 4th ed. " (Riddick et al., Wiley, 1986), and includes 557 chemicals with viscosity values at 25 °C (experimentally determined or approximated if the temperature of determination was among 10 and 25 °C)
- Model description: see field 'Justification for type of information', 'Attached justification' and 'any other information on Material and methods'
- Justification of QSAR prediction: see field 'Justification for type of information', 'Attached justification' and/or 'overall remarks' - GLP compliance:
- no
- Type of method:
- other: QSAR
- Temp.:
- other: 25.0 °C
- Parameter:
- dynamic viscosity (in mPa s)
- Value:
- >= 4.14 - <= 15.92
- Remarks on result:
- other: The model calculates the viscosity in centipoise (cP): 1 cP = 1 mPa·s.
Reference
Boundary values are given for the set of 8 constituents: the lowest one for C8 0EO and the highest one for C10 2EO (slightly higher than the one for C10 3EO). In all cases the mean absolute error for a subset of similar compounds to the query compound is lower than the one for an entire test set (=0.13 log unit, viscosity measured in cP), what indicates compliance with the applicability domain and reliability of the result.
Description of key information
4.14 -15.92 mPa s at 25 °C
Key value for chemical safety assessment
Additional information
The viscosity of the test substance was calculated with a scientifically approved QSAR model.
