For preschoolers (2–5 years), hydroxycitronellal is best treated with caution. It is mainly a skin allergen: some children can get allergic rashes or irritation after contact. Risks for cancer or effects on growth are low according to available data, but the chance of a skin reaction is the main concern.
If you are caring for a 2–5 year old, prefer fragrance-free products for daily use (lotions, shampoos, soaps). If you need to use a product that lists this ingredient or simply ‘fragrance,’ do a small patch test on a tiny area of the child’s inner forearm or behind the ear and wait 48 hours to check for redness or a rash. Avoid applying fragranced products to broken skin, the face, or around the eyes. If your child has eczema or very sensitive skin, avoid this ingredient altogether.
Avoid if your child has a history of skin reactions or eczema. This ingredient is listed by several regulatory bodies as a known human allergen or skin sensitizer (for example: the EU Cosmetics Directive, European Union assessments, the U.S. Environmental Protection Agency, and industry guidance from the International Fragrance Association). Products or certification programs may restrict its use unless safety is proven. Stop use and see a doctor if you notice a spreading rash, swelling, blistering, breathing trouble, or any signs of a severe allergy.
