For adults (grown-ups), this ingredient is usually okay in products made for skin or mouth when used as the label says. Most adults won’t have serious problems, but some people may get skin irritation, an allergic reaction, or breathing sensitivity.
Use only products formulated for adults and follow the label. Do a small patch test (apply a small amount behind the ear or on the inner arm and wait 24–48 hours). Don’t put it on broken or irritated skin. If you notice redness, swelling, itching, or any breathing trouble, stop using it and see a doctor. If you are pregnant or trying to conceive, check with your healthcare provider before regular use because animal studies showed reproductive effects at higher doses.
Avoid ingesting the raw ingredient—food use is restricted by U.S. food authorities. Some countries restrict the concentration allowed in cosmetics (Japan has limits). Laboratory and animal studies have flagged possible reproductive effects and nerve-cell effects; an environmental agency has noted possible human toxicity and environmental harm. Watch for skin irritation, signs of allergy, or respiratory symptoms and follow product concentration limits and manufacturer instructions. Sources include national regulatory guidance (U.S. food authority, Japan Ministry of Health), Environment Canada findings, and published laboratory and animal studies.
