Reference
Endpoint:
particle size distribution (granulometry)
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 marketed or used in a non solid or granular form
Percentile:
D50
Remarks on result:
other: Migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.

Description of key information

The substance "2-propanol and 2-butanol production, distn. residues" is liquid at ambient temperature (melting point <-80 °C, boiling point starting at 70 °C and higher) and therefore a study for particle size distribution does not need to be conducted.

Additional information

In accordance with column 2 of REACH Annex VII, the study does not need to be conducted because the substance is a liquid.
