Description of key information

No effects up to the limit of water solubility. 

Key value for chemical safety assessment

Additional information

In general, all effect values on the microbial toxicity for the category of SCAE C2 -8 have been found well above the limit of water solubility.

In the key study, the acute toxicity of Isopropyl myristate to Pseudomonas putida was tested according to a national guideline and GLP (Coenen 1988). Nominal test substance concentrations ranged from 0.004 to 18 mg/L. After an incubation time of 18 hours, no real toxicity threshold could be determined, since all the measured extinction values were very close to the reference. Therefore, an EC50(18h) > 10 mg/L was stated based on an estimated limit of water solubility.
