Key result

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

Substance observed to be non-flammable in the preliminary test. Thus, it was not necessary to proceed with the full burning rate test. Material was observed to melt upon contact with flame, but does not ignite. Melted material almost immediately hardens and darkens to an amber color.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

Rosin acid derivative was determined to be non-flammable.

Executive summary:

A preliminary test was performed using rosin acid derivative. Material was packed in a non-combustible, non-porous, and low heat-conducting surface mold and formed into an unbroken train about 250 mm long, 20 -mm wide, and 10 -mm high. Flame was was applied to the substance for a maximum of 2 minutes. The substance melted and darkened but did not ignite. No combustion was propagated along the chain. As per test guidelines, the test substance was considered not to be highly flammable and no further testing was required. The study was conducted in accordance with EU method A.10 and was GLP compliant. Therefore the study is considered reliable without restrictions.

Additional information

The study was conducted in accordance with EU method A.10 and was GLP compliant. A preliminary test was performed using rosin acid derivative. Material was packed in a non-combustible, non-porous, and low heat-conducting surface mold and formed into an unbroken train about 250 mm long, 20 -mm wide, and 10 -mm high. Flame was was applied to the substance for a maximum of 2 minutes. The substance melted and darkened but did not ignite. No combustion was propagated along the chain. As per test guidelines, the test substance was considered not to be highly flammable and no further testing was required. The study is considered reliable without restrictions.

Experimental GLP studies, conducted according to EU A10 and A12, were provided for Resin acids and rosin acids, esters with glycerol (Chilworth Technology, 2010a). Resin acids and rosin acids esters with glycerol was determined not to be highly flammable. The sample does not generate flammable gases in contact with water. No gas generation or spontaneous ignitions were observed during any of the tests. The test material in this study may be thought of as forming a part of the registered substance composition. Information provided to support readacross.

Justification for classification or non-classification

None of the Rosin ester substances are considered to be flammable, flammable on contact with water or pyrophoric.

Resin acids and rosin acids, esters with glycerol is not highly flammable, there is no spontaneous ignition or evolution of gases in contact with water and pyrophoricity is waived on the basis of handling and use.
