4-Decenal, 9-hydroxy-5,9-dimethyl-

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

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
In accordance with the column 2 of REACH annexVII, the particle size distribution study (required in section 4.5) does not need to be conducted if the substance is marketed or used in a non solid or granular form

Experimental studies were conducted under GLP for the determination of physicochemical properties of the substance, in particular freezing point < -50°C, and normal boiling point = 268°C, confirming, in a Weight-of-Evidence approach, the description of the test sample as a liquid. Therefore, the result is retained as key data.
