- according to guideline
- Guideline:
- EPA OPPTS 830.7220 (Boiling Point / Boiling Range)
- Deviations:
- yes
- Remarks:
- The deviation has no negative influence on the outcome of the study because no distinct boiling point was observed.

- Specific details on test material used for the study:
- Identity: Benzyldimethyl(octadecyl)ammonium chloride

Composition: Benzyldimethyl(octadecyl)ammonium chloride
Content: Cationic activity 97.6%
Expiry date: 06/2019
Storage conditions: Room temperature, in dark, in closed vessel - Key result
- Atm. press.:
- 101.3 hPa
- Decomposition:
- yes
- Decomp. temp.:
- ca. 200 °C
- Remarks on result:
- other: Test substance decompose before boiling
- Conclusions:
- Under the study conditions, the initiation of thermal decomposition of the substance was determined to be at 200°C.
- Executive summary:
A study was conducted to determine the boiling point of the test substance, C18 ADBAC (active: 97.6%), using siwoloboff method, according to OECD Guideline 103, EU Method A.2 and EPA OPPTS 830.7220, in compliance with GLP. A small amount of the test substance was filled in a boiling tube and packed to a filling level of approximately 5 to 10 mm height. Due to the fact that at the atmospheric pressure of the test laboratory a boiling temperature of the test substance was not observed a correction of the boiling temperature to standard atmospheric pressure was not necessary. The sample was heated up to 155˚C, after the melting of the sample the boiling temperature capillary was put in the boiling tube and the measurement was started with heating range of 1˚C/min up to 300˚C end temperature. A boiling temperature could not be determined up to 300˚C, as the test substance decomposed above 200˚C. Under the study conditions, the initiation of thermal decomposition of the substance was determined to be at 200°C (Wannenwetsch, 2017).

Description of key information
The boiling point of the test substance was determined using the siwoloboff method according to OECD Guideline 103, EU Method A.2 and EPA OPPTS 830.7220 (Wannenwetsch, 2017 and Scymaris, 2017).
Key value for chemical safety assessment
Additional information
Value used for CSA: no boiling temperature identified due to decomposition
Two studies were available with the test substance:
- Study 1: the test substance decomposes at >200°C (Wannenwetsch, 2017)
- Study 2: boiling point was determined to range from 159 to 165°C (Scymaris, 2017). The measured BP value is suspected to be influenced by residual solvent/impurities.
Overall, both studies support that the test substance will not form gas at room temperature. However, the study with relatively more pure form of the test substance, showing decomposition before boiling has been considered as the key study.
