Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint:
substances / mixtures which in contact with water emit flammable gases
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water
Endpoint:
flammable gases
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a solid
Endpoint:
pyrophoric liquids
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a solid
Endpoint:
pyrophoric solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied
Endpoint:
self-heating substances / mixtures
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied
Endpoint:
flammable solids
Type of information:
read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
weight of evidence
Study period:
2009-09-04 to 2009-12-07
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
For details and justification of read-across please refer to the read-across report attached to IUCLID section 13.
Reason / purpose for cross-reference:
read-across source
Key result
Test procedure:
burning rate test: preliminary screening test
Burning time:
> 4 min
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

Results:

The flame of the gas burner did ignite the test substance pile. The test substance melted and burned with a blue flame. After removal of the ignition source, the flame extinguished immediately and no propagation of combustion was observed.

Interpretation of results:
GHS criteria not met
Conclusions:
In conclusion, it can be stated that L-lactide is considered as 'not highly flammable'.
Executive summary:

A preliminary screening test was performed for the determination of the flammability of L-lactide (purity 100%). No propagation of combustion of the test substance along 200 mm length of the pile within 4 minutes was observed. According to the guideline, performance of a main study for the determination of the burning rate of the test substance was not required. Based on the results, the test substance is considered as 'not highly flammable'.

This information is used in a read-across approach in the assessment of the target substance. For justification of read-across please refer to the attached read-across report (see IUCLID section 13).

Conclusions:
In conclusion, it can be stated that D-lactide is considered as 'not highly flammable'.

Executive summary:

A preliminary screening test was performed for the determination of the flammability of D-lactide. No propagation of combustion of the test substance along 200 mm length of the pile within 4 minutes was observed. According to the guideline, performance of a main study for the determination of the burning rate of the test substance was not required. Based on the results, the test substance is considered as 'not highly flammable'.

Description of key information

Flammability of D-lactide and L-lactide was determined. Results are considered fully valid also for dilactide as dilactide is a mixture of D- and L-lactide isomers. The flame of the gas burner ignited the test substance pile. The test substance melted and burned with a blue flame. After removal of the ignition source, the flame extinguished immediately and no propagation of combustion was observed. Based on test results for D-lactide and L-lactide it is concluded that lactides are not highly flammable.

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Dilactide is not classified as a flammable solid, flammable gas, pyrophoric liquid, pyrophoric solid, self-heating substance or as substance which emits flammable gases in contact with water.
