Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
boiling point
Type of information:
read-across based on grouping of substances (category approach)
Adequacy of study:
key study
Study period:
6th to 27th August 2010
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
Guideline study conducted to GLP. The endpoint has been read-across from a structurally similar substance; Phenol, Dodecyl-, sulfurized, carbonates, calcium salts, overbased; CAS No: 122384-87-6/68784-26-9, therefore the reliability of the study has been reduced.
Justification for type of information:
The substance is composed of a series of alkylated phenol species of variable composition and a highly refined, lubricant base oil necessary to
The substance is one of a series of chemically similar materials each of which is composed of the same highly refined, lubricant base oil and different although closely related series of alkylated phenol species. Although the alkylated phenol series present in the different substances are considered different enough to warrant separate registrations, they are none the less all extremely closely related and the EPIWIN program predicts very similar properties for a number of representative structures. This high degree of similarity, in conjunction with the presence of the same base oil, which is itself understood to have a strong influence on the overall physicochemical properties of the substances is considered sufficient grounds to allow the use of read across between the different members of these “phenate” substances for the studies conducted to examine their physicochemical properties.

The sample did not boil before 250°C.

Conclusions:
The boiling point was determined to be > 250°C.
Executive summary:

The test is conducted in accordance with the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A2.

The boiling point was determined to be > 250°C.

This study is being used as read across from Phenol, tetrapropenyl-, sulfurized, carbonates, calcium salts, overbased CAS No: 122384-87-6/68784-26-9.

Description of key information

Additional information

The key study for this endpoint is considered to have a reliability rating of 1, however the study is being used as read across to a structurally similar substance (EC 701 -251 -5) as there was no available data to fulfil this endpoint for the test material and so the reliability rating will be reduced to 2, according to the criteria of Klimisch, 1997.
