Adequacy of study:
key study
Study period:
August 2012
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: non-GLP
Qualifier:
according to
Guideline:
OECD Test Guideline 114 (Viscosity of Liquids)
GLP compliance:
no
Type of method:
rotational viscometer (dynamic)
Temp.:
20°C
Parameter:
dynamic viscosity (in mPa s)
Value:
31 505
Remarks on result:
other: Shear rate 1.0 s-1
Temp.:
40°C
Parameter:
dynamic viscosity (in mPa s)
Value:
7 192
Remarks on result:
other: Shear rate 1.0 s-1
Conclusions:
The sample showed a slight shear thinning behavior at 20°C, and a shear thinning behavior at 40°C. The average viscosity at 20°C with a shear rate 1.0 s-1 was 31505 mPa.s. The average viscosity at 40°C with a shear rate 1.0 s-1 was 7192 mPa.s
Executive summary:

Viscosities were measured at shear rates ranging from 1 to 100s-1. Two replicates of each temperature were performed.
