For adults: this ingredient can be irritating or even cause burns if concentrated. In most skin products it’s used in tiny amounts to balance acidity and is considered a moderate risk when properly formulated.
Use finished skincare or hair products from trusted brands that list this ingredient. Do not use raw or concentrated solutions on skin. If you want to check first, do a small patch test on the inside of your forearm and wait 24 hours. If you feel strong burning, redness, or stinging, stop using it and rinse with water. If you handle concentrated forms (for example, in a workplace or DIY cleaning/soap making), wear gloves, eye protection, and follow safety instructions.
Do not apply to broken, irritated, or sensitive skin. Avoid contact with eyes — if it gets in the eyes, rinse thoroughly and seek medical help. Regulatory and safety panels note use restrictions and concentration limits (EU cosmetics rules and industry safety reviews) and occupational guidance flags handling risks (EU GHS / workplace rules). Limited evidence shows it can cause skin or eye irritation (U.S. National Library of Medicine). Keep all concentrated forms away from children and pets.
