Expert Verdict

Significant data gap — no standalone toxicological data identified. CPSR requires read-across justification from structurally analogous long-chain fatty acids (e.g., stearic acid, behenic acid class). Impurity profile (PAHs, heavy metals) should be verified depending on source (synthetic vs. plant-derived wax).
