For preschoolers (ages 2–5) terpineol is not among the most dangerous ingredients, but it is a common cause of skin allergies and irritation. Most children will be fine, but sensitive toddlers and children with eczema or a history of skin reactions are at higher risk.
If you use a product that contains terpineol on a 2–5 year old: do a small patch test first on the inner forearm and wait 24–48 hours for any redness or rash; use only low-frequency, short-term application; avoid use on broken or inflamed skin; prefer fragrance-free products for daily use, especially for kids with sensitive skin or eczema; stop use immediately and wash the area if any irritation appears and see a pediatrician if it gets worse.
Watch for skin redness, itching, swelling or blistering after using a product that contains terpineol — these are signs of an allergic reaction (this ingredient is listed as a known human allergen by the EU cosmetics authority). There are also reported contamination concerns (formaldehyde) in some supplies of terpineol; choose reputable brands and products that disclose testing or avoid the ingredient if your child has sensitive skin. Note: regulatory notes also show limited food use approval and that environmental agencies consider some environmental toxicity concerns — these are not the main risks for short-term skin use but are other considerations when choosing products.
