Description of key information

Long-term toxicity to aquatic algae:
Results of a study with di-isodecyl phthalate ester (DIDP; CAS #68515-49-1) show that DIDP will not produce toxicity to algae at or below its maximum attainable water solubility.

Key value for chemical safety assessment

Additional information

The data used to characaterize the algal toxicity of di-isodecyl phthalate ester (DIDP; CAS #68515-49-1) ester are consistent with the data for several high molecular weight phthalate diesters summarized by Staples et al. (1997). These data show that high molecular weight phthalate diesters do not produce toxicity to algae at or below their maximum attainable water solubliity. The algal dataset includes results for one species, Selenastrum capricornutum (new name: Pseudokirchnerella subcapitata).
