Chromium (III) hydroxide

Flammability

Administrative data

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 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

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

other:

Justification for type of information:

The material has been heated in air to attempt melting point assessment and instead it appears to decompose. There was no evidence of violent exotherm or combustion. There is no reaction in water to product flammable gases or by-productsInorganic salts are not typicallly considered likely to auto-ignite on heating. Inorganic salts or chromium are not conisdered combustible
