 Principles of method if other than guideline:
 The partition coefficient (log Kow) value for the test substance were estimated using the group contributions methodology of Molinspiration (miLogP2.2  November 2005). Since the test substance is a UVCB, the log Kow values were predicted for the individual constituents using SMILES codes as the input parameter.

 Conclusions:
 Using the group contribution method, of Molinspiration (miLogP 2.2), the weighted average partition coefficient (log Kow) value for test substance was predicted to be 3.01.
 Executive summary:
The partition coefficient (log Kow) value for the test substance, C810 MIPA was predicted using the group contribution method, of Molinspiration (miLogP 2.2) program. Since the test substance is a UVCB, the log Kow values were predicted for the individual constituents using SMILES codes as the input parameter. Using the group contribution method, the log Kow values for the individual constituents of the test substance ranged from 1.6 to 4.63. All constituents meet the molecular weight and log Kow descriptor domain criteria. Given that the constituents are structurally very similar and vary only in the carbon chain length, a weighted average value, which considers the percentage of the constituent in the substance, was considered to dampen the errors in predictions (if any). Therefore, the weighted average log Kow value was calculated as 3.01. Overall, considering either the individual log Kow predictions for the constituents or the weighted average values, the test substance is expected to be less hydrophobic with a good absorption and low accumulation potential. Therefore, the log Kow predictions for the test substance using Molinspiration (miLogP 2.2), can be considered to be reliable with moderate confidence.

 Executive summary:
The partition coefficient (log Kow) value for the test substance, C8 10 MIPA was predicted using the EPA and ASNN based regression equations from ALOGPS V.2.1. Since the test substance is a UVCB, the log Kow values were predicted for the individual constituents using SMILES codes as the input parameter. Using the EPA and ASNNbased regression equations, the log Kow values for the individual constituents of the test substance ranged from 1.27 to 4.15. All constituents meet the Eindices, molecular weight and number of nonhydrogen atoms descriptor domain criteria. Further, given that the constituents are structurally very similar and vary only in the carbon chain length, a weighted average value, which considers the percentage of the constituent in the substance, was considered to dampen the errors in predictions (if any). Therefore, the weighted average log Kow value was calculated as 2.43.
