- Endpoint:
- viscosity
- Type of information:
- other: Expert assessment
- Adequacy of study:
- key study
- Study period:
- 2010
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Assessment based on properties of the substance and chemical structure.
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Assessment based on properties of the substance and chemical structure
- GLP compliance:
- no
- Type of method:
- other: Visual assessment
- Temp.:
- other:
- Parameter:
- kinematic viscosity (in mm²/s)
- Value:
- > 20.5
- Remarks on result:
- other: Substance is a viscous liquid with greater viscosity than water.
- Conclusions:
- An assessment based on the structure and properties of the substance was carried out. The substance is described as a 'viscous yellow liquid' and is observed to be more viscous than water.
- Executive summary:
The viscosity of the registered substance was determined via a visual assessment of the substance. Direct observations suggest the substance is more viscous than water and will not present an aspiration hazard if ingested. All test reports for work performed in 2010 on batch TSM 10/40 FA9110617 describe the substance as ‘viscous yellow liquid’ and indeed, warming is needed to assist pouring and mixing. An estimated value of > 20.5 mm2/s has been determined in the assessment.

- other: No information on used method provided
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Method 'LV M2 V30' was followed to perform the test. This method was not specified further.
- GLP compliance:
- not specified
- Type of method:
- rotational viscometer (dynamic)

- Conclusions:
- Rotational viscosimetry was applied to determine the viscosity of the test substance at 75, 85 and 95°C. Values found at the respective temperatures are: 450, 204 and 103 cP.
- Executive summary:
The viscosity of the test substance was determined using a rotational viscomiter at 75, 85 and 95°C. Values found at the respective temperatures are: 450, 204 and 103 cP.

Description of key information
The viscosity of the registered substance was estimated via a visual assessment. The substance was observed to be more viscous than water. A viscosity value of 20.5 mm^2/s was estimated.
Key value for chemical safety assessment
- Viscosity:
- 20.5 mm²/s (static)
- at the temperature of:
- 20 °C
Additional information
The viscosity of the registered substance was determined via a visual assessment of the substance. Direct observations suggest the substance is more viscous than water and will not present an aspiration hazard if ingested. All test reports for work performed in 2010 on batch TSM 10/40 FA9110617 describe the substance as ‘viscous yellow liquid’ and indeed, warming is needed to assist pouring and mixing. In addition, a read-across study was conducted on the BPA 2PO which gave a viscosity of 450 cP at 75°C, 204 cP at 85°C and 103 cP at 95°C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
