Reference
Endpoint:
vapour pressure
Type of information:
calculation (if not (Q)SAR)
Adequacy of study:
weight of evidence
Study period:
2017
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Based on Annex VII column 2 if the melting point is between 200-300°C a limit value based on a recognised calculation method is sufficient to assess the end point. The substance decomposes at T > 200°C.
Qualifier:
no guideline required
Principles of method if other than guideline:
Calculation by MPBPVP v1.43
Type of method:
other: calculation
Temp.:
25 °C
Vapour pressure:
ca. 0 Pa
Remarks on result:
other: -
Conclusions:
The calculated Vapour pressure of Acid Brown 58 is predicted to be 1.69E-017 Pa.
