Frequently asked questions
- Is limonene safe during pregnancy?
- NTP two-generation studies showed no developmental effects. ECHA flags H317/H410 only (sensitisation, aquatic). Pregnancy authorities do not list as avoid.
- Is limonene safe while breastfeeding?
- No evidence of reproductive or lactation-specific toxicity; no harmonised H360/H361 classification. Topical exposure could lead to low systemic absorption and therefore low potential for transfer into breastmilk, so exposure scored as low but measurable. Sources: CIR, ECHA Annex VI, PubChem.
- Is limonene safe for baby skin?
- No infant-specific reproductive/safety signals documented and no harmonised reproductive classification. Because infant skin has a higher surface-area-to-weight ratio and a less mature barrier, dermal exposure is increased relative to adults; therefore exposure score is increased by +1 to reflect moderate measurable absorption. Primary safety concern for limonene remains skin sensitization (especially oxidized limonene), not reproductive toxicity. Sources: CIR, ECHA Annex VI, EWG, PubChem.
