RE: : CASRN 68610

- 90 -2
Dear Sir/Madame: As requested by US EPA, encloses a summary of t he data requested by EPA under the above TSCA Test Rule, available data on CASRN 68610

- 90

- 2 and structurally related analogues, as well as the data being submitted to the EPA with this letter are listed in Table 1 (attached). The information is being submitted in both paper (one copy) and electronic (disk) formats. With the exception of physical

- chemical properties, information submitted on environmental fate as well as ecological and mammalian toxicity is for , a close structural analogue of the tes t rule chemical , 2

- butenedioic acid (2E)

- , di

- C8

- 18

- alkyl esters (68610

- 90

- 2)

. Because several studies are in German, robust summaries of these studies in English are also provided. If this information is inadequate, translations of the original studies can be provided upon request from EPA. Two studies requested by EPA are not included in this submission. The first, a n OECD 422 (combined repeated dose toxicity study with reproduction/developmental toxicity screening) on is being finalized. BASF expects it can provide this study to EPA in the next several weeks. The second, is a chronic toxicity study in Dap hnia . Although this study has not been performed, 68610

- 90

- 2 is unlikely to pose a significant exposure potential or environmental hazard given (a) its poor water solubility (< 0.15 mg/L), (b) biodegradation characteristics (> 60% @ 28 days), and (c) low acute toxic ity as demonstrated by tests on chemical surrogates in three different aquatic receptors

1Firm Providing D ata :

Contact Person :

B ased on the information provided, believes EPA has sufficient screening level information to assess the risks posed by 68610

- 90

- 2 to human health and environmental safety. However, is willing to consider providing EPA with copies of studies on surrogate chemistries summarized in Table1, but not provided at this time, if the Agency believes this additional information will aid its assessment of 68610

- 90

- 2. looks forward to EPA’s thoughts on the information provided. Should you have any questions or concerns, please contact the person noted above. Sincerely,
