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-reference
Reason / purpose:
data waiving: supporting information
Reference
Endpoint:
appearance / physical state / colour
Type of information:
other: observation
Adequacy of study:
key study
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)
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)
- Determination of the odour at room temperature and comparison to other substances of characteristic odours
GLP compliance:
no
Physical state at 20°C and 1013 hPa:
solid
Key result
Form:
solid: particulate/powder
Colour:
light brown
Odour:
other: low, smelly
Substance type:
organic
Conclusions:
- physical state at 20°C and 1013 hPa: solid
- colour: light brown
- odour: low, smelly
Executive summary:

The visual description of the colour, the physical state (at 20°C and 1013 hPa) and the determination of the odour resulted in the following: the test substance 2-Butyne-1,4-diol, reaction products with 1,2-oxathiolane 2,2-dioxide and sodium hydroxide is a light brown solid with low, smelly odour (at 20°C and 1013 hPa).
