Water solubility was determined using the flask method and a procedure designed to be compatible with Method A.6 Water Solubility of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 105 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
RESULTS
Water solubility of the test item was determined to be less than 1 x 10E-06 g/L at 20.0 ± 0.5 °C.

- Remarks on result:
- other: Shaking for 48 hours
- Details on results:
- On completion of the equilibration period, the samples were clear and colorless with excess test item present. After centrifugation, the supernatant was taken for analysis. The supernatant was visually observed to be clear/colorless and free from un-dissolved test item.
It was observed that the duplicate results for each of the three samples were somewhat inconsistent. This may have been in part due to variability in the extraction procedure or that the entire excess test item had not been removed from the samples even though they visually appeared to. For this reason the results were taken as limit values based on the highest result as a worst case scenario. Based on the representative structure of the test item, the water solubility
would be expected to be very low.
To investigate the variable results further, additional duplicate aliquots of the three samples were re-centrifuged and passed through a 0.2 μm filter. After extraction they were analyzed as previously. Curiously no test item peak was evident in the sample extracts. This suggested that either any excess test item present was removed by filtration or that the test item adsorbed to the filter. Although, in either case these results suggested the water solubility of the test item is very low.
No peak at the retention time of the test item was observed in the matrix blanks. - Conclusions:
- Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The water solubility of the test item has been determined to be less than or equal to 2.04 x 10-3 g/L of solution at 20.0 ± 0.5 °C. - Executive summary:

- Justification for type of information:
- To register EC453-460-3 under REACH program, a read-across approach for fulfillment of the endpoints has been adopted. EC453-460-3 is an aliphatic ester and fits the description of polyol esters category in HPV program (High Production Volume, US-EPA). The distinguishing feature of polyol esters category is that the fatty acids were linked to one or more of the multiple hydroxyl groups present in the polyol (alcohol portion of ester). The focus of this correspondence is to support read across to EC613-848-7 (target) which provided key studies to determine hazard profile of EC453-460-3 (target), published information on other structurally analogous polyol esters were served as supporting evidence.
