Particle size distribution (Granulometry)

Administrative data

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

Cross-reference

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

Endpoint:

appearance / physical state / colour

Type of information:

other: observation

Adequacy of study:

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

data from handbook or collection of data

Remarks:

Peer-reviewed assessment report (attached in section 13)

Qualifier:

according to guideline

Guideline:

EPA OPPTS 830.6302 (Color)

Version / remarks:

old Guideline number given in assessment report (US EPA PAG 63-2)

Qualifier:

according to guideline

Guideline:

EPA OPPTS 830.6303 (Physical State)

Version / remarks:

old Guideline number given in assessment report (US EPA PAG 63-3)

Qualifier:

according to guideline

Guideline:

EPA OPPTS 830.6304 (Odor)

Version / remarks:

old Guideline number given in assessment report (US EPA PAG 63-4)

Principles of method if other than guideline:

- visual description of the colour and the physical state (at 22°C)
- determination of the odour at 22°C

GLP compliance:

yes

Specific details on test material used for the study:

Purity: 99.1%

Physical state at 20°C and 1013 hPa:

liquid

Key result

Form:

other: Slightly viscous liquid

Colour:

brown

Odour:

other: Slightly organic

Substance type:

organic

Conclusions:

As information was provided via a peer-reviewed assessment report, it can be considered as sufficiently reliable. Results:

- physical state at 22°C: slightly viscous liquid
- colour: brown
- odour: slight organic

Executive summary:

The visual description of the colour and the physical state (at 22°C) and the determination of the odour according to EPA OPPTS 830.6302, 830.6303 and 830.6304 (GLP) result in the following:

the test substance is a slightly viscous brown liquid with a slight organic odour.
