Conclusions:
Under the conditions of the test, the visocisty of of the test substance was determined to be 3.06 mm²/s at 20 ± 0.5 ºC.
Executive summary:

In a non-GLP compliant viscosity study conducted in line with standardised guidelines OECD 114 and EPA OPPTS 830.7100, the viscosity of the test substance was determined to be 3.06 mm2/s at 20 ± 0.5 ºC.

Description of key information

The viscosity of 1-phenylethyl acetate was determined to be 3.06 mm²/s at 20 ± 0.5 ºC according to a study performed in line with OECD Guideline 114 and EPA OPPTS 830.7100.

Additional information

The key study (Givaudan, 2011h) was conducted in line with standardised guidelines but not to GLP with a sufficient level of detail to assess the quality of the study. The study was performed to a sufficient standard and was assigned a reliability score of 2 in accordance with Klimisch (1997).
