Applicant's summary and conclusion

Conclusions:

The effective concentration (EC50) value of 5-hydroxyisopthalic acid in aquatic invertebrate (Daphnia Magna) in a 48 hr study on intoxication was estimated to be 316.8365 mg/L. .Thus considering CLP Criteria for aquatic classification of the substance , it is concluded that 5-hydroxyisopthalic acid shall not exhibit short term toxicity to aquatic invertebrate (Daphnia Magna).
