adults • Skin contact product
For adults: this ingredient is generally safe in normal skin products. Most people can use it without problems. It has a low chance of causing long-term harm, but it can irritate skin, eyes or lungs in some people, especially at higher strength.
If you are an adult using a product with this ingredient: do a small patch test on your inner forearm before using widely; avoid applying to broken or irritated skin; avoid products that are sprayed near the face if you have breathing problems; if you use active treatments (like strong acids, retinoids, or prescription actives), watch for extra irritation because this ingredient can increase how much other substances get into your skin. If you are pregnant or breastfeeding and worried, check with your health care provider.
Limited evidence shows it can cause skin, eye or respiratory irritation (source: 2017 toxicology study and European Chemicals Agency). It is listed as a penetration enhancer (source: Cosmetic Ingredient Review), so it may increase absorption of other ingredients — avoid combining it with strong actives without guidance. Some product certification programs restrict its use unless a maker provides extra safety data. Watch for redness, stinging, rash, or breathing trouble and stop use if these occur; seek medical help if breathing problems or severe reactions happen.
