The physico-chemical properties of the category members are similar or follow a regular pattern over the category. Most of the members of the category have been tested for their flash point and they show flash points between 121.5 and 206°C. These very high values are related to the similarity of structures of the category members and the lack of flammability hazard.

Since the target substance belongs to the category, it can be deduced that its flash point will be ≥121.5°C . 

 

Interpretation of results:

GHS criteria not met

Conclusions:

Based on the experimental studies on the source chemicals of the category, the flash point of the target substance, ethyl decanoate is considered to be ≥ 121.5 °C.

Additional information

Justification and rationale of the category approach for Ethyl Caprate

This category group covers fatty acid chains linked to alcohols via an ester function. It includes mono-constituent substances and UVCB substances with varying fatty acid chain lengths from C8 to C18-unsaturated and alcohol types (including ethanol, isopropanol, octanol, hexanol and 2-ethylhexanol). This category group was made in order to provide sufficient information for physico-chemical, environmental, ecotoxicological and toxicological characterization of ethyl decanoate (CAS 110-38-3). Some data on the target substance of the category are available.

This category includes:

-       Target substance:

o       Ethyl decanoate (CAS 110-38-3)

-       Source substances:

o       Ethyl undecylenate (CAS 692-86-4)

o       Isopropyl laurate (CAS 10233-13-3)

o       Octyl octanoate (CAS 2306-88-9)

o       Isopropyl myristate (CAS 110-27-0)

o       Dodecanoic hexyl ester (CAS 34316-64-8)

o       Ethyl linoleate (CAS 544-35-4)

o       Ethyl oleate (CAS 111-62-6)

o       2-Ethylhexyl laurate (CAS 20292-08-4)

o      Fatty acids, coco, 2-ethylhexyl esters (CAS 92044-87-6)

Summary of available studies on source substances for the flash point

Most of the members of the category have been tested for their flash point according to EU Method A.9, ASTM D93 or DIN 51584 methods. Based on these available studies the flash points are between 121.5°C and 206°C at 1013 hPa for the category members. These very high values are related to the similarity of structures of the category members and the lack of flammability hazard. So it can be deduced that the flash point of Ethyl decanoate will be ≥ 121.5°C

Additionally, a certificate of analysis provided a flash point value for the target substance. The flash point of ethyl decanoate was assessed according to ASTM D93 (only method and results provided) and was defined at 218.5°C at 991 hPa.

Conclusion

According to the Regulation (EC) NO. 1907/2006, Annex XI, 1.5, a Read-Across Category for " Medium Chain Fatty Acid (from C8 to C18 unsat.) and alcohol esters (from C2 to C8) was performed in order to provide information on Ethyl decanoate.

This category was based on common and shared properties as:

- common functional group,

- common precursors and the likelihood of common impurities resulting from common process of manufacturing,

- chemically structurally similar breakdown products obtained via the same biological processes into the organisms, and

- constant pattern in the changing of the potency of the properties across the category.

Based on the results obtained for the category members, it can be deduced that the target substance Ethyl decanoate will show a flash point ≥ 121.5°C, and does not present any flammability hazard. Additionally, a certificate of analysis was given and the melting point of ethyl decanoate was determined experimentally as 218.5°C at 991 hPa (according to ASTM D93 method). This experimental value confirms the lack of flammability and it is considered as the relevant flash point of Ethyl decanoate based on a weight of evidence approach.
