Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.10 (Flammability (Solids))
GLP compliance:
yes (incl. certificate)
Remarks:
Ministry of Labor, Health and Social Affairs of North Rhine-Westphalia, Düsseldorf, Germany
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

The test substance melted when approached by the ignition flame. The substance didn't burn down or burn up. No further testing

was required.

The test substance is classified as not highly flammable when tested according EU Test A.10.

Interpretation of results:
not classified based on GHS criteria
Executive summary:

In a burning rate test according EU Method A.10 the test substance melted and did not burn down or burn up in the preliminary test. No further testing was required. sodium p-chloro-m-cresolate (hydrated form) is not highly flammable

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
the study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture
Interpretation of results:
GHS criteria not met
Executive summary:

Based on experience in handling and use and the chemical structure flammability on contact with water is not to be expected. sodium p-chloro-m-cresolate (hydrated form) is not flammable on contact with water.

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
Interpretation of results:
GHS criteria not met
Executive summary:

Based on experience in handling and use and the chemical structure pyrophoricity is not to be expected. Sodium p-chloro-m-cresolate (hydrated form) has no pyrophoric properties.

Description of key information

non flammable by ignition

no pyrophoricity

no flammability in contact with water

Key value for chemical safety assessment

Flammability:
not classified

Additional information

The substance melted in preliminary screening test and did not propagate combustion (EU Method A.10).

Based on experience in handling and use and the chemical structure pyrophoricity and flammability on contact with water are not to be expected.

Justification for classification or non-classification

The available data on flammability of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008, and are therefore conclusive but not sufficient for classification:

The substance melted and did not propagate combustion in a preliminary screening test according EU Method A.10. Therefore the substance is not be classified as a flammable solid.

Based on chemical structure and experience in handling and use, pyrophoricity and flammability on contact with water are not expected.
