Conclusions:
The test substance, H2925 (CAS No. 68130-53-0) was assessed for the characteristic of viscosity.
The viscosity was determined to be 35.73 cSt at 20°C and 21.80 cSt at 40°C.
Executive summary:

This study was conducted using the test substance H2925 (CAS No. 68130-53-0). This study was conducted in accordance with OECD Guidelines for the Testing of Chemicals/Section 1: Physical-Chemical properties Guideline 114 using the methods described in the approved protocol and STILLMEADOW, Inc. SOPs. There were no deviations from the protocol that affected the quality or outcome of the study.

 

The test substance, H2925 (CAS No. 68130-53-0) was assessed for the characteristic of viscosity.

The viscosity was determined to be 35.73 cSt at 20°C and 21.80 cSt at 40°C (35.73 mm2/s at 20°C and 21.80 mm2/s at 40°C).
