Type of information:

experimental study

Adequacy of study:

key study

Study period:

28 March 2017 - 26 May 2017

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

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

Qualifier:

no guideline required

Principles of method if other than guideline:

The test methods described are designed to be compatible with the procedures indicated by the following internationally accepted guidelines and recommendations:
• Council Regulation (EC) No 440/2008 (as amended) of 30 May 2008
• OECD Guidelines for Testing of Chemicals
• REACH Regulation (EC) No 1907/2006 of the European Parliament and of the Council of 18 December 2006

Test System:
The determination of the color and the physical state was performed by visual assessment.
The odor was not determined as there was insufficient information to definitively confirm the test item did not present an inhalation hazard.

GLP compliance:

no

Identification: C.I. Solvent Yellow 175 Solid
Batch: ZA07202016
Purity: >99%
Expiry date: 18 July 2019
Storage conditions: room temperature in the dark

Physical state at 20°C and 1013 hPa:

solid

Key result

Form:

solid

Remarks:

The sample of test item was visually assessed at 20.0 ± 0.5 ºC to be a hard opaque coarse solid.

Colour:

The sample of test item was visually assessed at 20.0 ± 0.5 ºC to be yellow in colour.

Odour:

other: The odor was not determined as there was insufficient information to definitively confirm the test item did not present an inhalation hazard.

Substance type:

organic

Conclusions:

The color of the test item was visually assessed to be yellow at 20.0 ± 0.5 ºC.
The physical state of the test item was visually assessed to be hard opaque coarse solid at 20.0 ± 0.5 ºC.
The odor was not determined as there was insufficient information to definitively confirm the test item did not present an inhalation hazard.

Executive summary:

An aliquot of test item was transferred to a clear glass open topped container and equilibrated in a water bath at 20.0 ± 0.5 ºC for 30 minutes. The sample was then placed on a white background and viewed under natural light. The physical state and color was visually assessed. The odor was not determined as there was insufficient information to definitively confirm the test item did not present an inhalation hazard. The sample of test item was visually assessed at 20.0 ± 0.5 ºC to be a hard opaque coarse solid with a yellow color.
