- Endpoint:
- oxidising solids
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- supporting study
- Reason / purpose for cross-reference:
- read-across source
- Reason / purpose for cross-reference:
- read-across: supporting information
- Sample tested:
- other: modelling
- Parameter:
- other: heat of decomposition
- Remarks on result:
- other: see "Any other information on results"
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Structural aspects and estimated thermodynamic properties indicate that the substance must not be considered to have oxidising properties.
- Endpoint:
- oxidising solids
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidising properties and hence, the classification procedure does not need to be applied

Structural aspects: Initially, it can be stated that partially unsaturated TEA-Esterquat does not contain any typically reactive structural groups that would indicate an exothermal reaction with combustible material. Partially unsaturated TEA-Esterquat is a mixture of mono-, di- and triesters with chain lengths of C16, C18 and C18 (unsaturated). In this context, it is explicity noted that the components of partially unsaturated TEA-Esterquat contain an identical subset of structural increments (Benson groups), which is why in this statement, no further differentiation is made between the different ester chains and the C18 -chain length is used as the chemical lead. The unsaturated chain is an exemption, with the Benson groups (CH2 -(C, =C) and =C-(2C)) which however can be considered not to be reactive structural groups.
Maximum heat of decomposition
Partially unsaturated TEA-Esterquat*: -411 cal/g (interploated value)
Dimethylsulfuric acid**: -786 cal/g (interploated value)
Monoester: -363 cal/g
Diester: -352 cal/g
Triester: -309 cal/g
*calculation performed for the product partially unsaturated TEA-Esterquat as a mixture of the key identified individual components
**calculation performed for each key identified individual components of the product partially unsaturated TEA-Esterquat
This is a measure of the energy to be released from the material itself, and has been shown to be highly correlated with the tendency of a material to deflagrate or detonate. A high rating is assigned by CHETAH if the calculated maximum enthalpy of decomposition is more exothermic than 700 cal/g (2929 J/g).
Difference between heat of combustion and heat of decomposition
Partially unsaturated TEA-Esterquat*: -7181 cal/g (interploated value)
Dimethylsulfuric acid**: -1681 cal/g (interploated value)
Monoester: -7841 cal/g
Diester: -8406 cal/g
Triester: -8654 cal/g
The heat of combustion forpartially unsaturated TEA-Esterquat was calculated as -7592 cal/g (interploated value). Since the heat of decomposition is much lower, this can be seen as an indication of a low tendency to be plosive.
Oxygen Balance
Partially unsaturated TEA-Esterquat*: -243%
Dimethylsulfuric acid**: -63%
Monoester: -264%
Diester: -283%
Triester: -291%
A compound with exactly the amount of oxygen required for total combustion has an oxygen balance of 100%. Thus a compound with a negative oxygen balance is oxygen deficient. Experience has shown that this value is primarily of relevance for compounds consisting of C, H, N, and O.
Description of key information
There is no indication for oxidizing properties of Fatty acids, C18 unsatd., mono and diester with triethanolamine , di-Me sulfate-quaternized as the substance does not contain any structural groups associated with oxidising properties.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
In accordance with column 2 of REACH Annex VII, testing for oxidising properties does not need to be conducted, as the substances does not contain any structural groups known to be correlated with a tendency to react exothermally with combustible material. In addition, the thermodynamic calculations and the negative oxygen balance for the read-across substance partially unsaturated TEA-Esterquat indicate that the substance may rather be assessed as combustible than to have oxidising properties. In conclusion, the substance is not considered to have oxidising properties.
Justification for classification or non-classification
There is no indication for oxidizing properties of Fatty acids, C18 unsatd., mono and diester with triethanolamine , di-Me sulfate-quaternized as the substance does not contain any structural groups associated with oxidising properties.
