For adults: usually okay in rinse-off hair products (shampoos, conditioners) when made and used correctly. There are some industry and regulatory warnings, so it isn’t risk-free.
Choose rinse-off products (shampoo or conditioner) rather than leave-on creams or scalp treatments if they contain this ingredient. Prefer brands that say they control impurities or test for contaminants. Do a small patch test on the inside of your arm before first use. If the product is meant to be left on the skin, avoid it or use only if the brand provides clear safety testing and impurity limits.
Watch for redness, itching, stinging, or swollen skin or eyes — these can happen and may mean you’re sensitive. Industry safety reviews flag two issues: (1) restrictions on leaving this ingredient on the skin (Cosmetic Ingredient Review and related safety assessments) and (2) contamination risk from related chemicals that can form nitrosamines (noted by regulatory sources such as ECHA and Environment Canada). If a product doesn’t state safe use or impurity controls, avoid leaving it on the skin and consider choosing a different product.
