Frequently asked questions

Is poly(linseed oil) safe during pregnancy?
No harmonised CLP classification or SCCS/CIR reproductive hazard flag was found for poly(linseed oil). CIR evaluations of linseed/flaxseed seed oil conclude it is safe as used in cosmetics, and ECHA registration dossiers exist for linseed oil, but no harmonised H360/H361 classifications or pregnancy‑contraindicating listings were identified. (CIR; ECHA registration).
Is poly(linseed oil) safe while breastfeeding?
No data or regulatory classification indicating reproductive or lactation hazard for polymerized linseed oil; CIR’s safety conclusion for linseed/flaxseed oil supports ‘safe as used’ for topical cosmetic use and no breast‑feeding specific contraindication was found. Avoid topical application to nipples during breastfeeding as a general precaution for topical products (clinical guidance).
Is poly(linseed oil) safe for baby skin?
No evidence of infant‑specific reproductive hazard. Polymerized linseed oil is a high‑molecular‑weight, film‑forming oil (low dermal systemic availability); adult topical exposure is expected to be negligible. Per the scoring rules, infant exposure score is raised by +1 because baby skin has higher permeability and the ingredient has measurable but limited topical use — no infant‑specific absorption/toxicity data were found. (CIR; ECHA registration).
