Applicant's summary and conclusion

Conclusions:
 The result is:           44.3 mN/m
 Therefore, according to this test, it was considered that the test material is surface active (surface tension < 60 mN/m).
Executive summary:

The surface tension of a solution of Tetrahydro Citral in ultrapure water (90% of the saturation concentration) was determined according to the OECD Guideline No. 115, using the ring method.

 The result is:           44.3 mN/m

 Therefore, according to this test, it was considered that the test material is surface active (surface tension < 60 mN/m).
