Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2018-03-29 - 2018-04-10

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)

Deviations:

no

GLP compliance:

Key result

Test procedure:

burning rate test: preliminary screening test

Burning time:

ca. 60 s

Remarks on result:

other: The test item melted and showed only a local burning for approx. 60 s. No propagation of the flame could be observed and thus, the main test was not necessary.

Preliminary Test

The test item melted and the molten test item started to burn locally after applying the flame for about 30 s. After approx. 60 s burning time the local burning extinguished without further propagation.

Main Test

In the preliminary test the test item melted and showed only a local burning for approx. 60 s without propagation. Thus, the performance of the main test was not necessary.

Interpretation of results:

other: not classified based on EU GHS criteria and UN Transport Regulation

Conclusions:

The test item 'Decanoic acid, 3-[[6-deoxy-2-O-(6-deoxy-α-L-mannopyranosyl)-α-L-mannopyranosyl]oxy]-, 1-(carboxymethyl)octyl ester, mixt. with 1-(carboxymethyl)octyl 3-[(6-deoxy-α-L-mannopyranosyl)oxy]decanoate' is
- not classified as readily combustible solid in class 4.1 according to the UN Transport Regulation.
- not classified as flammable solid according to GHS / CLP Regulation EC 1272/2008 Annex 1: 2.7.

Executive summary:

It was tested whether the test item 'Decanoic acid, 3-[[6-deoxy-2-O-(6-deoxy-?-L-mannopyranosyl)-?-L-mannopyranosyl]oxy]-, 1-(carboxymethyl)octyl ester, mixt. with 1-(carboxymethyl)octyl 3-[(6-deoxy-?-L-mannopyranosyl)oxy]decanoate' should be classified as a highly flammable solid, readily combustible solid and flammable solid with respect to the UN Transport Regulation (Class 4, Division 4.1) and GHS / CLP Regulation EC 1272/2008 (Annex 1: 2.7), respectively.

The test item 'Decanoic acid, 3-[[6-deoxy-2-O-(6-deoxy-α-L-mannopyranosyl)-α-L-mannopyranosil-1-(carboxymethyl)octyl ester, mixture with 1-(carboxymethyl)octyl 3-[(6-deoxy-α-L-mannopyranosyl)oxy]-decanoate' melted and showed only a local burning for approx. 60 s without propagation.

The test item is classified as follows:

- UN Transport Regulation: The product has not to be classified as readily combustible solid in class 4.1 according to the UN Transport Regulation.

- GHS (CLP Regulation EC 1272/2008: Annex 1: 2.7): The product has not to be classified as flammable solid according to GHS / CLP Regulation EC 1272/2008 Annex 1: 2.7.

Description of key information

flammability (using UN Manual of Tests and Criteria Test N.1):

- the substance is not classified as readily combustible solid of Class 4 Division 4.1 of the UN Transportation Regulation and

- the substance is not classified as flammable solid according to GHS / CLP Regulation.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

According to CLP classification criteria, the substance does not meet the criteria for classification and labelling for this endpoint, as set out in Regulation (EC) No. 1272/2008; the substance also does not meet the criteria for classification as readily combustible solid in class 4.1 according to the UN Transport Regulation.
