About

Methyl Cyclooctanecarboxylate is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Methyl cyclooctanecarboxylate is a synthetic ester with a complex cycloaliphatic structure. It carries multiple hazard classifications including H315 (skin irritation), H319 (eye irritation), and H335 (respiratory irritation), which significantly limit its usable concentration in cosmetic products. While not specifically listed in EU cosmetic restriction annexes, the mandatory hazard labeling and the practical concentrations permitted substantially restrict its utility in cosmetic formulations.
