Oxidising properties

Link to relevant study record(s)

Reference

Endpoint:

oxidising liquids

Type of information:

other: Expert judgement based on Annex VII section 7.13, column 2 of REACH legislation

Adequacy of study:

weight of evidence

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: State of the art review of oxidising properties.

Remarks:

KL2 due to RA

Justification for type of information:

Refer to the section 13 for details on the read across justification. The oxidising property study with the read across substance is considered sufficient to fulfil the information requirements as further explained in the provided endpoint summary.

Principles of method if other than guideline:

The chemical structure of individual constituents (>10%) 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.

Key result

Sample tested:

test mixture as specified

Parameter:

preliminary test

Remarks on result:

not measured/tested

(a) Assessment according to UN Recommendation:

For read across substance, Oils, vegetable, deodorizer distillates, the classification procedures for oxidizing properties need not to be applied according to the mentioned UN-recommendations because one of the assessment criteria is met (O is bonded to C only).

(b)Assessment according to REACH Guidance: Experimental testing of the individual components of the test substance for oxidizing properties would not be necessary according to the REACH Guidance because one of the assessment criteria is met (O is bonded to C / H only).

(c) Determination of structural oxygen deficiency:

The following equation of reaction is applied as model for the combustion/decomposition of stearic acid:

C18H36O2 ----->18 CO2+ 26 O2 + 18 H2O

indicating a consumption of oxidants during combustion/decomposition of stearic acid.

The following equation of reaction is applied as model for the combustion/decomposition of triglyceride of stearic acid:

C15H110O6 -------> 57CO2 + 81.5O2 + 55H2O

indicating a consumption of oxidants during combustion/decomposition of triglyceride of stearic acid.

Interpretation of results:

GHS criteria not met

Conclusions:

Based on the results of the read across study, the test substance, 'soaps, stocks, vegetable oil, acidulated' is not expected to show oxidising properties

Executive summary:

The chemical structure of the read across substance ‘oils, vegetable, deodorizer distillates’ 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). Through evaluation of the properties of the different components of read across substance it is considered unlikely that the read across substance would release oxidizing components during decomposition/combustion and thus it is not expected to react exothermically with other combustible matter. As an expert statement it can be concluded that the read across substance is considered incapable of reacting exothermically with a combustible material. Therefore, it can be assumed to be inert in terms of oxidizing properties (Meinerling, 2010b). Based on the results of the read across study, the test substance, 'soaps, stocks, vegetable oil, acidulated' is not expected to show oxidising properties.

Description of key information

The chemical structure of ‘Soaps, stocks, vegetable oil, acidulated’ 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).

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Justification for classification or non-classification

Similar to 'oils, vegetable, deodorizer distillates', ‘soaps, stocks, vegetable oil, acidulated’ does not contain any chemical groups associated with oxidising properties considering the guidance provided in section R.7.1.13.3 of Chapter R.7a: REACH Technical Guidance Document as well as the Appendix 6 of the UN's Recommendations on the Transport of Dangerous Goods, Manual of Test and Criteria 4th ed (Revised Edition, 2003). Therefore it does not require classification according to the CLP criteria (EC 1272/2008).
