Six assays were performed during the test, the temperature values obtained for the corrected boiling point varied between 280.4 and 281.8 °C. The mean value for the boiling point is explained as the mean of at least two assays for which the boiling point value are in

the range of the estimated accuracy of the method: ± 0.5 °C up to 326.9 °C and ± 2.0 °C above 326.9 °C.

Two assays were contained between the range for the boiling point and two assays.

Conclusions:
The mean corrected boiling point of the test item is 280.5 ± 0.5°C .
Executive summary:

The boiling melting point of the test item (= substance EC 939-455-3) was investigated in a GLP-compliant study performed in accordance with OECD Guideline 103 (Boiling point/boiling range) and EU Method A.2 (Boiling Temperature). The mean boiling point of the test item was 280.5 ± 0.5°C.

Description of key information

The boiling point of the substance 1-Propanaminium, N-(3-aminopropyl)-2-hydroxy-N,N-dimethyl-3-sulfo-, N-(C8-18(even numbered) acyl) derivs., hydroxides, inner salts (EC 939-455-3) was investigated in a GLP-compliant study (Ricau, 2013) performed in accordance with OECD Guideline 103 (Boiling point/boiling range) and EU Method A.2 (Boiling Temperature). The mean boiling point of the substance was 280.5 ± 0.5°C.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
