Administrative data

Endpoint:
surface tension
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because based on structure, surface activity is not expected or cannot be predicted
the study does not need to be conducted because surface activity is not a desired property of the material
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING

In accordance with column 2 of REACh Annex VII 7.6, 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.
As presented under Section 1, the substance is a Reaction mass of three inorganic calcium salts (fluoride, sulfate, and carbonate, the last being also considered as inorganic, though it contains carbon). Therefore, no structural hydrophilic-lipophilic features typical of surfactants is present. Moreover, inorganics are generally known to have no impact or slightly increase the surface tension of water.
Additionally, the present substance is not intended to be used as a surfactant (i.e. not a desired property).
Therefore no additional information is required.
