Deviations:

no

GLP compliance:

yes (incl. QA statement)

A test substance is considered highly flammable when it ignites spontaneously in contact with water, or evolves a flammable gas at a minimum rate of ≥ 1 litre/kg of the substance per hour.

None of the components of the test substance does contain groups that might lead to ignition in contact with water and/or to the evolution of a flammable gas. The molecular structures of impurities at < 1% were not taken into account.

 

In conclusion, Lowinox^® CPL is considered ‘not highly flammable’ in contact with water.

 

Interpretation of results:

other: not highly flammable in contact with water

Conclusions:

In conclusion, Lowinox® CPL is considered ‘not highly flammable’ in contact with water.

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

autumn 1996

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

other: The study has been performed according to OECD and/or EC guidelines, and according to GLP principles.

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

GLP compliance:

yes

Test procedure:

burning time (test type not further specified)

Remarks:

or specified in description of method (migrated information)

Remarks on result:

other: test substance melted to form a glassy liquid which did not ignite so no flame propagation took place

initial evaluation: test substance melted on the application of heat to form a dark amber/black liquid; yellow flames were observed as well as white smoke; on cooling the liquid was found to form a glassy mass which was prone to cracking; this mass broke into flakes when touched

train test: test substance melted to form a glassy liquid which did not ignite so no flame propagation took place

on cooling an amber/black solid was formed

Based on these results Wingstay L-HLS is not classified as (highly) flammable.

Interpretation of results:

non flammable

Deviations:

no

GLP compliance:

yes (incl. QA statement)

A test substance is considered pyrophoric when it ignites within five minutes of coming in contact with air.

None of the components of the test substance contain groups that might lead to ignition in contact with air. Moreover the test substance was handled under normal laboratory conditions, e.g during the determination of the adsorption coefficient. It demonstrated that the test substance does not ignite in contact with air at room temperature. The molecular structures of impurities at < 1% were not taken into account.

 

In conclusion, Lowinox^®CPL has no pyrophoric properties.

Interpretation of results:

other: not pyrophoric

Conclusions:

In conclusion, Lowinox®CPL has no pyrophoric properties.

Description of key information

3 GLP studies were available to cover the endpoint related properties flammability, flammability in contact with water and pyrophoric properties. In none of the tests or evaluations the substance was found to be flammable.

Key value for chemical safety assessment

Flammability:

non flammable

Additional information

In the flammability experiment, the test substance melted (yellow flames were observed as well as white smoke) to form a glassy liquid which did not ignite so no flame propagation took place. On cooling an amber/black solid was formed.

Based on evaluation of the structural features of the test substance it was concluded that none of the components of the test substance contains groups that might lead to ignition in contact with water and/or to the evolution of a flammable gas. The molecular structures of impurities at < 1% were not taken into account. Also, none of the components of the test substance contains groups that might lead to ignition in contact with air. Moreover the test substance was handled under normal laboratory conditions, e.g. during the determination of the adsorption coefficient. It demonstrated that the test substance does not ignite in contact with air at room temperature.

Based on both the experimental results and the evaluation of the structural features it was concluded that phenol, 4 -methyl-, dicyclopentadiene and isobutylene is non flammable.

Justification for classification or non-classification

Based on the experimental result and the evaluation of the structural features it was concluded that phenol, 4 -methyl-, dicyclopentadiene and isobutylene is non flammable. Classification according to Directive 67/548/EC and the CLP Regulation is therefore not required.
