For adults: usually safe in small amounts but it commonly causes skin allergic reactions in some people. Most adults with normal skin won’t have problems, but those who react to fragrances are more likely to get redness, itching or a rash.
If you are buying or using a product that may contain eugenol (often in clove or spicy/fragrance blends): do a small patch test on the inside of your forearm and wait 24–48 hours before regular use; avoid products with strong fragrance if you have sensitive skin or a history of fragrance allergy; do not apply to broken or inflamed skin; stop use and rinse if you get redness, itching or swelling; check ingredient lists for “eugenol,” “clove oil,” or generic “fragrance” if you need to avoid it.
Allergy risk: eugenol is listed as a known human allergen by cosmetic regulators and the fragrance industry — avoid if you have fragrance sensitivity (Sources: EU Cosmetics Directive labeling rules; International Fragrance Association). Usage limits and restrictions: some cosmetic programs restrict or require proof for its use (Source: cosmetic use restrictions). Organ system notes: one regulator classifies it as expected to be toxic or harmful at higher exposures, so avoid concentrated use and do not ingest undiluted material (Source: Environment Canada). Cancer and reproductive concerns are low in the available data (Sources: IARC; US FDA).
