Endpoint:
boiling point
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
key study
Study period:
14 September 2015 - 13 February 2016
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:

An OECD 103 GLP study for a similar substance is available and is used within a read-across approach. The composition of source and target substance is described and discussed in detail in the attached supporting information as well as the read-across justification.

Reason / purpose for cross-reference:
read-across source
Qualifier:
according to guideline
Guideline:
EU Method A.2 (Boiling Temperature)
Qualifier:
according to guideline
Guideline:
OECD Guideline 103 (Boiling point/boiling range)
Principles of method if other than guideline:
not applicable
GLP compliance:
yes (incl. QA statement)
Remarks:
certificate attached to study report
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
Type of method:
differential scanning calorimetry
Specific details on test material used for the study:
Test item without emulsifier was investigated.

Target substance:

Amidoamine 2 (UVCB, low nitrogen):
Former chemical name: Amides, from diethylenetriamine and hydrogenated palm oil
CAS No.: 1618093-67-6
New chemical name: Glycerides, C16-18 (even numbered) and their amidation products with diethylenetriamine
Physical state: pale yellowish solid at 20 °C
Batch No.: PU50070067
Purity: 100 % (UVCB)
Storage condition of test material: Room temperature, protected from light
Stability: stable under test conditions
Key result
Atm. press.:
>= 99.3 - <= 99.8 kPa
Decomposition:
yes
Decomp. temp.:
ca. 161 °C

As a result of the low rate of enthalpy change during decomposition, the onset temperature could only be approximated. Similar thermographic profiles were obtained using air and nitrogen atmospheres. This indicates that the decomposition in both air and nitrogen atmospheres is most likely due to a thermal mechanism.

Conclusions:
The test item has been determined to decompose from approximately 161 °C (434 K) at 99.3 to 99.8 kPa. As the test item decomposed, no value for boiling temperature could be determined.
It is considered likely, that the target substance Amidoamine 2 (UVCB, low nitrogen) will have a comparable boiling point/decomposition temperature as Amidoamine (UVCB) based on the similar chemical composition.
Executive summary:

In the Klimisch 1 GLP study the boiling point of amidoamine test item was determined with the DSC method according to OECD 103 and EU method A.2. The test item shows a boiling and /or decomposition at ca. 161 °C (at 99.3 to 99.8 kPa) according to the definition in the OECD Guideline 103. This study is considered relevant for the risk assessment. It is considered likely, that the target substance Amidoamine 2 (UVCB, low nitrogen) will have a comparable boiling point/decomposition temperature as Amidoamine (UVCB) based on the similar chemical composition.
