Administrative data

Endpoint:
flash point of flammable liquids
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids
Cross-referenceopen allclose all
Reason / purpose:
data waiving: supporting information
Reference
Endpoint:
appearance / physical state / colour
Type of information:
other: observations
Adequacy of study:
key study
Study period:
2017-05-30
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: acceptable company statement (specification data on manufactured product requires strict adherence to conform within range and so is reliable)
Reference:
Composition 0
Qualifier:
no guideline followed
Principles of method if other than guideline:
- Visual description of the colour (in daylight by an observer with normal colour vision) and the physical state (at 20 °C and 1013 hPa)
GLP compliance:
no
Test material information:
Composition 1
Physical state at 20°C and 1013 hPa:
solid
Key result
Form:
solid: particulate/powder
Colour:
light yellow
Odour:
other: not determined out of health and safety reasons
Substance type:
organic
Conclusions:
- physical state at 20°C and 1013 hPa: solid powder
- colour: light yellow
Executive summary:

According to the observations made, we certify that this substance can be described as follows:

- Physical state (at 20 °C and 1013 hPa): solid powder

- Colour: light yellow

Reason / purpose:
data waiving: supporting information
Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2016-06-10
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
Remarks:
in-house data
Reference:
Composition 0
Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Deviations:
no
GLP compliance:
no
Type of method:
differential scanning calorimetry
Test material information:
Composition 1
Key result
Melting / freezing pt.:
134.2 °C
Conclusions:
The melting point was determined according to a scientifically valid method, hence, the following result for the test material can be considered as reliable: The melting point of the test item was determined to be 134.2 °C.
Executive summary:

The melting point of 2,2'-methylenebis[6-cyclohexyl-p-cresol] was determined to be 134.2 °C by DSC in a OECD 102 study.
