Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

REPORTING FORMAT FOR THE ANALOGUE APPROACH

1. HYPOTHESIS FOR THE ANALOGUE APPROACH
This read-across is based on the hypothesis that source and target substances have similar (eco)toxicological properties because
• they share structural similarities with common functional groups: One quaternised ethanolamine moiety, one to three, mainly two ester groups with a typical UVCB distribution with long-chain fatty acids of natural origin. The molecular structure is almost identical.
• they are manufactured from similar resp. identical precursors (triethanolamine, long-chain fatty acids, dimethyl sulphate) under similar conditions. Therefore, common breakdown products via physical and biological processes, which result in structurally similar chemicals are evident
• A constant pattern in the changing of the potency of the properties across the TEA-Esterquats by chain-length and the grade of esterification is not observed, because the fatty acid chain-length distribution is too narrow and similar and the distribution of mono-, di-, and tri-esters is identical. Some variation caused by variation in C=C double bonds may occur and will be discussed at the relevant endpoint.

read-across source

In a preliminary test, the test item could not be ignited with a flame. Therefore the main test was not necessary to be conducted.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The flammability of the analogue source test substance was investigated in a study conducted according to EU-Method A.10. In a preliminary test, the test item could not be ignited with a flame. Therefore the main test was not necessary to be conducted.
Based on the results, the test substance is not a highly flammable solid in the sense of the consolidated version of Council Directive 67/548/EEC, Annex V, Method A.10 (Council Directive 92/69/EEC).

Description of key information

Not highly flammable.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

No experimental data are available for the target substance oleic acid-based TEA-Esterquat. However, the flammability was determined for the source substance partially unsaturated TEA-Esterquat. A justification for read-across is attached to Iuclid section 13.

Based on the results, the test substance is not a highly flammable solid in the sense of the consolidated version of Council Directive 67/548/EEC, Annex V, Method A.10 (Council Directive 92/69/EEC).

Justification for classification or non-classification

In a preliminary screening test according to EU method A.10., the flammability of the source substance partially unsaturated TEA-Esterquat was investigated. The test item could not be ignited with a flame. With this result the outcome of the screening test is negative and according to CLP classification criteria the substance is not classified.
