Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because surface activity is not a desired property of the material

Description of key information

The endpoint is waived.

Key value for chemical safety assessment

Additional information

Surface activity is not the desired property of the substance and moreover based on the chemical structure the substance will not have surface activity. According to ECHA Guidance on information requirements and chemical safety assessment. Chapter R.7a: Endpoint specific guidance p 78: The study needs only to be conducted if: based on structure, surface activity is expected or can be predicted; or surface activity is a desired property of the material and/or the solubility is less than 1 mg/L
