The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Key value for chemical safety assessment

Additional information

One publication evaluating the toxicity of1,2,3-propanetriyl trioleate(CAS No. 122-32-7) to algae is available (Kamaya, 2003). This test was conducted according to the US EPA Algal, Selenastrum capricornutum, growth test method 1003.0 (EPA 600/4-89/001). Selenastrum capricornutum was exposed for 96 hours to the test substance at 24 ± 1°C and cell concentrations were determined by means of a microscope and hemocytometer every 24 hours. Exponential growth in the control was maintained throughout all the testing period. After 96 hours of exposure, no inhibition of algal growth was observed in the treatment group compared to control values. Therefore, both IC50 (72 h) and IC50 (92 h) were determined to be > 5 mg/L (nominal concentration). Thus, no toxicity up to the limit of water solubility of 1,2,3-propanetriyl trioleate (< 0.05 mg/L)was observed.
