Endpoint:
appearance / physical state / colour
Type of information:
experimental study
Adequacy of study:
key study
Study period:
16 July 2019
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Appearance based on observations from other testing endpoints (surface tension) conducted on this substance at the same laboratory.
Reason / purpose:
reference to other study
Qualifier:
no guideline available
Principles of method if other than guideline:
Appearance based on observations from other testing endpoints conducted on this substance all at the same laboratory.
GLP compliance:
yes
Physical state at 20°C and 1013 hPa:
solid
Key result
Form:
solid
Remarks:
powder
Colour:
Creamy white
Substance type:
organic
Conclusions:
The appearance of the lyophilised form of the test substance was found to be off-white to pale yellow powder. The test substance is placed on the market in pelleted forms.
Executive summary:

The physical state and appearance of the test substance, C12 -18 TMAC were visually observed during testing of other endpoints. The appearance of the dried/lyophilised form of the test substance was reported to be creamy white, solid powder (Muckle, 2019). However, the test substance is placed on the market in solution form.

Description of key information

The physical state and appearance of the test substance were observed during the testing of other endpoints (Muckle, 2019).
