Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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
Endpoint:
surface tension
Type of information:
experimental study
Adequacy of study:
supporting study
Study period:
2009
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 115 (Surface Tension of Aqueous Solutions)
Deviations:
no
GLP compliance:
no
Type of method:
ring method
Surface tension:
73 mN/m
Temp.:
20 °C
Conc.:
169 g/L
Conclusions:
The surface tension of a 169.0 g/L solition of tin sulfate was determined to be 73 mN/m at 20.0°C
Executive summary:

The surface tension of a solution of the test item in water was determined according to OECD 115 in a non-GLP study. The surface tension of a 169.0 g/L solition of tin sulfate was determined to be 73 mN/m at 20.0 °C. This is equal to the typical surface tension of water at 20 °C.

Description of key information

In general the study does not need to be conducted, because surface activity is no desired propertiy of the material and in addition surface active properties can not be predicted based on the structure of the test item.

This is confirmed by a supporting study:

The surface tension of a solution of the test item in water was determined according to OECD 115 in a non-GLP study. The surface tension of a 169.0 g/L solition of tin sulfate was determined to be 73 mN/m at 20.0 °C. This is equal to the typical surface tension of water at 20 °C.

Key value for chemical safety assessment

Surface tension:
73
in mN/m at 20°C and concentration in mg/L:
169
