Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Adequacy of study:
weight of evidence
Study period:
Nov 2016
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model, but not (completely) falling into its applicability domain, with adequate and reliable documentation / justification
Remarks:
MPBPVP by EPI Suite v4.1 software
Justification for type of information:
No experimental data available. The validity of the model has been evaluated in accordance with the OECD validation principles (OECD, 2004; Worth et al, 2005; OECD, 2007). See attached report.

Description of key information

Modeling was conducted to evaluate the vapor pressure of one of the main constituents of the test substance, 3,5,5 trimethylhexanoic acid hexaesters of dipentaerythritol, according to EPI SUITE (MPBPWIN). It is expected that the substance has a negligible vapour pressure

Modeling was conducted to evaluate the vapour pressure of a second main constituent of the test substance, hexaesters of dipentaerythritol (with one molecule valeric acid and five molecules 3,5,5 trimethylhexanoic acid), according to EPI SUITE (MPBPWIN). It is expected that the substance has a negligible vapour pressure.

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
20 °C

Additional information

Based on QSAR estimations, the test substance has a vapour pressure close to 0 Pa.
