Endpoint:

Type of information:

read-across from supporting substance (structural analogue or surrogate)

Adequacy of study:

weight of evidence

Justification for type of information:

1. Hypothesis for the analogue approach:
The hypothesis for the analogue approach is that both the registration substance, Hydrocarbons, C9-C11, n-alkanes, isoalkanes, <2% aromatics (target substance), and the test substances, Hydrocarbons, C8-C11, n-alkanes, isoalkanes, <2% aromatics (source substance) and Hydrocarbons, C9-C12, n-alkanes, isoalkanes, <2% aromatics (source substance), are produced from the same Fischer-Tropsch substance, GTL Gasoil, by fractional distillation.

The source substances contain the all of the constituents of the target substance. The substances have constituents that are part of the same homologous series and have many constituents in common. The substances therefore have qualitatively similar properties (RAAF Scenario 2 applies).
2. Source and target chemical(s)
The source substance Hydrocarbons, C8-C11, n-alkanes, isoalkanes, <2% aromatics (GS 160) is composed of linear, branched and cyclic hydrocarbons of chain length C8-C11
The source substance Hydrocarbons, C9-C12, n-alkanes, isoalkanes, <2% aromatics, (GS 170) is composed of linear, branched and cyclic hydrocarbons of chain length C9-C12
The target substance, Hydrocarbons, C9-C11, n-alkanes, isoalkanes, <2% aromatics,(GS 180) is composed of linear, branched and cyclic hydrocarbons of chain length C9-C11.
3. Analogue approach justification
The constituents of the source and target substances are all hydrocarbons. Identical constituents have identical physicochemical profiles. The source substances cover the full carbon chain length of the target substance.

Description of key information

Flash point: 25 -47°C at 1013 hPa 

Additional information

There are no reliable measured flash point data for the submission substance. However, reliable data are available for related substances in the relevant carbon number range, including other Fischer-Tropsch process-derived substances.

In ISO 3679 studies using the rapid equilibrium method, which were conducted in compliance with GLP, Hydrocarbons, C8-C11, n-alkanes, isoalkanes, <2% aromatics (GTL Solvent GS160) and Hydrocarbons, C9-C12, n-alkanes, isoalkanes, <2% aromatics (GS170) had measured flash point values of 25 ± 2°C and 47 ± 2°C at 1013 hPa respectively. The results are considered to be reliable and are used as weight of evidence.

Hydrocarbons, C9-C11, n-alkanes, isoalkanes, cyclics, <2% aromatics has a measured flash point of 39-40°C at 1013 hPa using a closed cup method.
