Additional information

The toxicity of retinyl palmitate to microorganisms was investigated in two studies according to different guidelines (OECD 209 and DIN 38412, part 27) using different inoculums activated sludge (domestic) and Pseudomonas putida, resepctively. The results of this tests showed no toxicity to microorganisms neither to activated sludge (EC20 >1000 mg/L) nor to Pseudomonas putida (EC10 >10000 mg/L).
