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 toxicological properties because
- they are manufactured from similar or identical precursors under similar conditions
- they share structural similarities with common functional groups (corresponding to scenario 2 of the read-across assessment framework): both, the target and source substance, are aliphatic amines with C8-18 alkyl chains and acetate functions
- Two thirds (w/w) of the target substance Reaction product of lauryl-PDA/lauryl-DETA with chloroacetic acid (excluding the solvent water) are composed of the source substance DOPA-Glycinate. The remaining third of Reaction product of lauryl-PDA/lauryl-DETA with chloroacetic acid consists of other aliphatic amines and derivatives which are considered as structural analogues to those constituting the source substance DOPA-Glycinate and may therefore be expected to elicit comparable (eco)toxicological effects.

The read-across hypothesis is based on structural similarity of target and source substances. Based on available experimental data, including key physicochemical properties and data from acute toxicity, repeated dose toxicity, genotoxicity and short term ecotoxicity studies, the read-across hypothesis is supported by a quite similar toxicological profile of both substances.

(Eco)toxicological, physicochemical and environmental fate data are summarised in the data matrix; robust study summaries are included in the Technical Dossier in the respective sections.

Therefore, read-across from the existing ecotoxicity, environmental fate and toxicity studies conducted with the source substances is considered as an appropriate adaptation to the standard information requirements of the REACH Regulation for the target substance, in accordance with the provisions of Annex XI, 1.5 of the REACH Regulation.

Reason / purpose for cross-reference:

read-across source

Reason / purpose for cross-reference:

read-across: supporting information

Test procedure:

burning rate test: preliminary screening test

Remarks on result:

other: the test item melted in the preliminary test. A main test is therefore not required.

Interpretation of results:

GHS criteria not met

Description of key information

non-flammable (EU method A.10; read-across DOPA-Glycinate)

Key value for chemical safety assessment

Flammability:

not classified

Additional information

The flammability of the source substance DOPA-Glycinate (99% a.i.) was investigated in a study according to EU method A.10 (1992). The test item melted in the preliminary test. A main test is therefore not required. DOPA-Glycinate is non-flammable.
