Materials and methods

Principles of method if other than guideline:

The chemical structure of the test substance was examined for the presence of groups associated with oxidising properties according to UN recommendations (Appendix 6 of the UN's Recommendations on the Transport of Dangerous Goods, Manual of Test and Criteria 4th ed (Revised Edition, 2003) and Section R7.1.13.3 of the REACH guidance R.7a: Endpoint-specific guidance (May 2008). Expert judgment was applied to conclude on the oxidising properties of the test substance.

Results and discussion

Test results (Oxidising solids)

Key result

Parameter:

other: oxygen demand for the combustion of the individual components

Remarks on result:

other: No oxidising properties expected

Any other information on results incl. tables

The following equation of reaction is applied as model for the combustion of Fully hydrogenated high erucic acid rapeseed oil (with n1, n2, n3 nominating the chain length of the fatty acids R1, R2 and R3):

C3+n1+n2+n3H2(n1+n2+n3+1)O6 + 0.5+1.5 (n1+n2+n3) O2 → 3+n1+n2+n3 CO2 + 1+n1+n2+n3 H2O

The equation indicates a consumption of oxidants during combustion of fully hydrogenated high erucic acid rapeseed oil.

Applicant's summary and conclusion

Interpretation of results:

other: no oxidising properties

Remarks:

Migrated information

Conclusions:

The equation indicates a consumption of oxidants during combustion of fully hydrogenated high erucic acid rapeseed oil

Executive summary:

The chemical structure of the test substance was examined for the presence of groups associated with oxidising properties according to UN recommendations (Appendix 6 of the UN's Recommendations on the Transport of Dangerous Goods, Manual of Test and Criteria 4th ed (Revised Edition, 2003) and Section 7.1.13.3 of the REACH guidance R.7a: Endpoint-specific guidance (May 2008).

For all constituents of the product, it can be assessed through expert judgment based on the evaluation of the available data and the composition of the constituents that fully hydrogenated high erucic acid rapeseed oil will not show oxidizing properties.
