Any other information on results incl. tables
The colour of the test substance was determined to be “pale yellow” by visual observations and the hue was 5Y, the chroma was 2, and the value was 9 according to the Munsell Book of Color Matte Finish Collection from two independent investigators. The test substance was determined to be a “solid powder” and have a “pungent” and “gasoline-like” odour at 20.5°C.
Applicant's summary and conclusion
- Conclusions:
- The test substance is a pale-yellow solid with a pungent, gasoline-like odour.
- Executive summary:
The physical state determination was conducted on the aliquot from the colour determination by visual observation. The ambient room temperature was recorded. Two independent investigators were used to determine the physical state. The studies were done in accordance with OPPTS 830.6302, Color; OPPTS 830.6303, Physical State; and OPPTS 830.6304, Odor. The test substance is a pale-yellow solid with a pungent, gasoline-like odour.
