Specific details on test material used for the study:

Identification: 2,2'-methylenebis[6-(1-methylcyclohexyl)-p-cresol]
Appearance: White to cream powder
Batch: WWP4J0001
Purity/Composition: 92.2%
Test substance storage: At room temperature
Stable under storage conditions until: 03 September 2018 (retest date)
Purity/composition correction factor: Yes, correction factor is according to purity
Test substance handling: No specific handling conditions required

Test procedure:

burning rate test: preliminary screening test

Remarks on result:

substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

In contact with the flame of the gas burner the test substance melted, emitted yellow sparks and turned into a brown yellow residue. Grey smoke was observed. After removal of the ignition source, no propagation of combustion of the test substance was observed.

Interpretation of results:

GHS criteria not met

Conclusions:

No propagation of combustion of the test substance along 200 mm length of the pile within 4 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained, the test substance is considered ‘not highly flammable’.

Executive summary:

The aim of the study was to determine the physico-chemical properties for 2,2'-methylenebis[6-(1-methylcyclohexyl)-p-cresol].

 

The study was based on the following guidelines:

European Community (EC), EC no. 440/2008, Part A: Methods for the Determination of Physico-Chemical Properties, Guideline A.10: “Flammability (Solids)”, Official Journal of the European Union no. L142, May 31, 2008.

ST/SG/AC.10/11/Rev.5: Recommendations on the Transport of Dangerous Goods, Part III: Classification Procedures, Test Methods and Criteria Relating to Class 2, Class 3, Class 4, Division 5.1, Class 8 and Class 9, Test N.1: “Test Method for Readily Combustible Solids”, 2009.

 

The preliminary screening test was performed for the determination of the flammability of 2,2'-methylenebis[6-(1-methylcyclohexyl)-p-cresol].

 

No propagation of combustion of the test substance along 200 mm length of the pile within 4 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained, the test substance is considered ‘not highly flammable’.

Description of key information

Key value determined in a GLP accredited laboratory study performed in accordance with EU Method A.10 and UN Test N.1.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

The preliminary screening test was performed for the determination of the flammability of 2,2'-methylenebis[6-(1-methylcyclohexyl)-p-cresol].

 

No propagation of combustion of the test substance along 200 mm length of the pile within 4 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained, the test substance is considered ‘not highly flammable’.

Justification for classification or non-classification

Based on the results obtained, the test substance is considered ‘not highly flammable’ and therefore does not fulfill the requirements for classification.
