Additional information
Conclusion on classification
12-hydroxystearic acid demonstrates low toxicity for fish, invertebrates and algae, with L(E)C50 > 100 mg/L. Furthermore, the substance has low water solubility and a BCF of 53. Consequently, it does not qualify for environmental classification according to Directive 67/548/EEC or Regulation (EC) No. 1272/2008.
