For toddlers (1–2 years): limonene can cause skin irritation and allergic reactions in some children. It is a moderate concern — not the most dangerous ingredient, but use cautiously.
Prefer fragrance-free or products that do not list limonene or ‘fragrance/citrus’ for your toddler; if you must use a product with limonene, apply a small amount on the inside of the forearm and wait 24–48 hours to check for a reaction before wider use; avoid applying to broken skin, face, or diaper area; keep products fresh and stored in cool, dark places (oxidation increases allergy risk); never use undiluted citrus essential oils on a child.
Known allergen and skin irritant according to cosmetic safety and hazard labeling rules (European Cosmetics Directive and EU hazard labels) — watch for redness, itching, swelling, blisters, or a spreading rash; there are contamination reports (for example traces of formaldehyde) in safety records — avoid products with unclear ingredient sourcing; some regulatory lists restrict or require labeling of this substance — read labels and avoid products listing limonene or generic “fragrance.” If your child has breathing difficulty, swelling, or a severe reaction, seek medical care right away.
