Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From 16 May 2012 to 06 December 2012
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:

Reason / purpose for cross-reference:
reference to same study
Qualifier:
according to guideline
Guideline:
EU Method A.9 (Flash-Point)
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Remarks:
2012-12-15
Type of method:
equilibrium method closed cup

No flash point was observed up to 120.0 °C(corrected values).

At 120.0 °C, the test item boiled and overflowed of the dish just before the presentation of the flame. Then the test was stopped.

Results of the main test:

Based on the results of the preliminary test, no main test was performed.

Interpretation of results:
GHS criteria not met
Conclusions:
No flash point was observed up to 120.0 °C (corrected value).
Executive summary:

The flash point of the test item (= substance EC 939-455-3 in aqueous commercial product) was investigated in a GLP-compliant study performed in accordance with EU Method A.9 (Flash-Point) using a closed-cup equilibrium method. No flash point was observed up to 120.0 °C, temperature at which the test item started to boil.

The study was performed on a commercial product (aqueous solution) as the substance EC 939-455-3 is manufactured and used in a liquid form.

Description of key information

The flash 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) in aqueous solution was investigated in a GLP-compliant study (Colombies, 2013) performed in accordance with EU Method A.9 (Flash-Point) using a closed-cup equilibrium method. No flash point was observed up to 120.0 °C, temperature at which the mixture started to boil.

The study was performed on a commercial product (aqueous solution) as the substance EC 939-455-3 is manufactured and used in a liquid form.

Additional information

The flash 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) in aqueous solution was investigated in a GLP-compliant study (Colombies, 2013) performed in accordance with standard methods, without deviations. The study is considered as reliable (Klimisch 1) and was selected as key study for the endpoint.
