Frequently asked questions
- Is polyepsilon-lysine safe during pregnancy?
- No harmonised CLP reproductive classifications were found and there are no SCCS or CIR safety opinions indicating reproductive hazard. Toxicology literature and regulatory summaries for ε‑polylysine report negative findings in reproduction/teratology studies (manufacturer summary) and ADME work showing low systemic absorption after oral dosing. These sources do not indicate a reproductive hazard from typical cosmetic use. (Sources: JNC product/safety summary; ADME/toxicity PubMed literature).
- Is polyepsilon-lysine safe while breastfeeding?
- No evidence of reproductive or lactation-specific toxicity was identified and no harmonised classifications apply. Available ADME data indicate low systemic absorption, and no studies report transfer to milk; therefore breastfeeding risk from topical cosmetic use is not supported by the literature searched. (See PubMed ADME study; manufacturer safety summaries).
- Is polyepsilon-lysine safe for baby skin?
- No infant-specific reproductive or developmental hazards were identified. Mechanistic evidence for reproductive toxicity is absent. Dermal/topical absorption data are limited, but ε‑polylysine is a high‑molecular‑weight, water‑soluble cationic polymer with published ADME showing low absorption; however because infant skin has higher surface‑area‑to‑weight and an immature barrier, exposure score is increased by +1 to reflect a low but measurable exposure potential for babies (0–3 yr) from topical application. No baby‑specific toxicity data were found. (See PubMed ADME; INCI/CosIng listing; EWG).
