Chromium acetate

Acute Toxicity: inhalation

Administrative data

Endpoint:

acute toxicity: inhalation

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because exposure of humans via inhalation is not likely taking into account the vapour pressure of the substance and/or the possibility of exposure to aerosols, particles or droplets of an inhalable size

Justification for type of information:

Supplied as a water-based solution or a sticky-crystalline hydrated solid

Cross-reference

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

Endpoint:

melting point/freezing point

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

test procedure in accordance with generally accepted scientific standards and described in sufficient detail

Justification for type of information:

Assessment made by manufacturer and corresponds to handbook data.

Qualifier:

equivalent or similar to guideline

Guideline:

OECD Guideline 102 (Melting point / Melting Range)

Principles of method if other than guideline:

Maplelab Scientific Melting Point Device MPD02

GLP compliance:

no

Type of method:

capillary method

Specific details on test material used for the study:

Batch number of test material: B-03-3173

Key result

Melting / freezing pt.:

> 300 °C

Decomposition:

yes

Remarks:

To chromium oxide

Decomp. temp.:

> 300 °C

Experience from manufacture and use suggest that there is no specific melting point and instead the substance will oxidise at high temperatures.

Substance did not melt at the upper temperature limit of the meter, 300 °C; subsequently it was placed in a furnace at a temperature >400 °C, for a couple of hours. Also in this case, it was noticed that the substance did not melt.When heated to decomposition it developed acrid smoke and irritating fumes.

Conclusions:

Experience from manufacture and use suggest that there is no specific melting point and instead the substance will oxidise at high temperatures.

Executive summary:

Experience from manufacture and use suggest that there is no specific melting point and instead the substance will oxidise at high temperatures.
