VeriMomIs undecane safe during pregnancy?
No EU harmonised reproductive classification is listed for undecane and no CIR or SCCS safety opinion flags were located; the RIFM fragrance safety review (2020) and ECHA registration material do not identify reproductive/developmental concerns, supporting h=0 and m=0. Physicochemical and registry data (high log Kow but low polarity) and RIFM/ECHA sources indicate low but measurable dermal exposure from topical use, so exposure is scored e=1.

Frequently asked questions
- Is undecane safe during pregnancy?
- No EU harmonised reproductive classification is listed for undecane and no CIR or SCCS safety opinion flags were located; the RIFM fragrance safety review (2020) and ECHA registration material do not identify reproductive/developmental concerns, supporting h=0 and m=0. Physicochemical and registry data (high log Kow but low polarity) and RIFM/ECHA sources indicate low but measurable dermal exposure from topical use, so exposure is scored e=1. ([pubmed.ncbi.nlm.nih.gov](https://pubmed.ncbi.nlm.nih.gov/32937169/))
- Is undecane safe while breastfeeding?
- No evidence found for reproductive or lactation-specific toxicity or mechanistic endocrine activity in the reviewed literature or regulatory dossiers (h=0, m=0). Dermal/topical use could result in low but measurable maternal systemic exposure similar to pregnancy assessment, so e=1 for breastfeeding. ([pubmed.ncbi.nlm.nih.gov](https://pubmed.ncbi.nlm.nih.gov/32937169/))
- Is undecane safe for baby skin?
- No infant-specific toxicity data or signals for developmental/teratogenic effects were identified; regulatory sources and the RIFM review do not flag undecane as a reproductive/teratogenic hazard (h=0, m=0). Because undecane is a lipophilic alkane with measurable dermal absorption in some contexts (registry/SDS and physicochemical profiles) and infant skin has higher absorption/surface-area-to-weight, exposure is increased by one category to e=2 for baby skin.
