Expert Verdict

Cyclovinylmethicone may overlap with restricted cyclic siloxanes (D4/D5/D6); REACH/CLP status must be verified. Environmental persistence and bioaccumulation concerns may affect eco-label and COSMOS acceptability. Avoid high inhalation exposure in spray formulations without specific inhalation risk assessment.
