Key value for chemical safety assessment

Additional information

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. No surface active properties are expected, because of the absence of a hydrophobic tail in the structure.
