Type of information:
experimental study
Adequacy of study:
key study
Study period:
experimental dates: 17 Oct. 2016 to 25 Jan. 2017
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Data comes from the description of the test substance in the report on other physico-chemical property. No guideline is required according to REACh TGD. The test substance is adequately characterised. Therefore full validation applies.
no guideline required
Principles of method if other than guideline:
Visual observation (+ microscope)
GLP compliance:
yes (incl. certificate)
inspected on 11 & 12 October 2016 / signed on 28 Feb. 2017
Physical state at 20°C and 1013 hPa:
solid: particulate/powder
white to pale yellow
Substance type:

A picture of the test item under microscope is provided in the experimental report.

Executive summary:

The test substance was tested under GLP for other physico-chemical property. In the report, the sample is described as a white to pale yellow powder.

Description of key information

White to pale yellow powder.

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:

Additional information

Experimental studies were conducted under GLP for the determination of physicochemical properties of the substance, including fully reliable description of the test sample. The granulometry study was selected as key, as providing also a picture under microscope. The result is retained as key value
