Depends on conditions of use and exposure. A hazards-only based system is perhaps useful for ranking the potencies of similar acting compounds to prioritize which are the most of concern. However, for actual risk assessment, exposure considerations are just as important as hazards since anything in high enough concentrations can cause toxicity.
Every material has a safety data sheet, and possibly a food codex entry or pharmacopeia entry. In your case some of the items might be found in skin cream for external use but only as recommended in the safety documents.
