Applicant's summary and conclusion

Conclusions:
The mean water solubility was 5.97 +/- 2.3 mg/L.
Executive summary:

The water solubility of LMDT was determined using the slow-stir method. The test substance was placed in water and stirred for 24 hrs, and allowed to equilibrate for 1 hr. Triplicate samples were then analyzed using TOC analysis. Three additional samples were taken at 48 hrs. The mean water solubility at 20 degrees C was 5.97 +/- 2.3 mg/L.
