Applicant's summary and conclusion

Conclusions:
In conclusion, the surface tension of a 90% saturated solution of the test substance in water is 38.6 mN/m. Based on the criteria of the
EEC guideline, it is concluded that the test substance should be regarded as a surface active material
Executive summary:

In a GLP compliant, guideline 'surface tension of aqueous solutions' test the surface tension of a 90% saturated solution of the test substance in water was calculated to be 38.6 mN/m. Based on the criteria of the EEC guideline, it is concluded that the test substance should be regarded as a surface active material
