Description of key information

Read across data  are available for  DL-Alpha-Tocopheryl acetate, a precursor of main tocopherols of the mixed tocopherols.. The respiration rate of microorganisms in presence of DL-Alpha-Tocopheryl acetate was tested by a oxygen consumption test according to ROBRA focusing on the respiration of Pseudomonas putida. After 30 minutes an EC10 > 10000 mg/l was determined (BASF AG, 1991). 

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
10 000 mg/L
