Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
key study
Study period:
06.12. – 07.12.2010
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
Remarks:
Guideline compliant study but tested above limit of water solubility.
Qualifier:
according to
Guideline:
EU Method A.5 (Surface Tension)
Deviations:
no
Qualifier:
according to
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Deviations:
no
GLP compliance:
no
Type of method:
ring method
Key result
Surface tension:
72.8 mN/m
Temp.:
20 °C
Conc.:
0.045 g/L
Conclusions:
tin disulfide has no surface active properties.
Executive summary:

The surface tension was determined with the ring method according to EC A.5 and OECD 115. The surface tension of a 0.045g/L solution of tin disulfide was 72.8 mN·m-1. The used concentration of tin disulfide is several orders of magnitude above the water solubility of the tin disulfide and therefore the results should be interpreted with care. However, since the undissolved material seems to have no effect on the surface tension which is close to the surface tension of water, this result is still considered acceptable.

The result is considered relevant and reliable for the further risk assessment.

Additional information

In the Klimisch 2 key study (Paß 2011) the surface tension was determined with the ring method according to EC A.5 and OECD 115. The surface tension of a 0.045 g/L solution of tin disulfide was 72.8 mN·m-1. The used concentration of tin disulfide is several orders of magnitude above the water solubility of the tin disulfide and therefore the results should be interpreted with care. However, since the undissolved material seems to have no effect on the surface tension which is close to the surface tension of water, this result is considered acceptable.

The result is considered relevant and reliable for the further risk assessment.
