Frequently asked questions

Is tristearin safe during pregnancy?
Tristearin (glyceryl tristearate, CAS 555-43-1) is a triglyceride (ester of glycerol and stearic acid) used as an emollient. There is no harmonised CLP classification for reproductive toxicity (ECHA Annex VI), no SCCS/CIR reproductive safety flags specific to tristearin, and no peer‑reviewed evidence of reproductive or teratogenic effects in humans or animals. Sources consulted: ECHA Annex VI (no harmonised classification), PubChem (toxicology summary), CIR/CosIng listings.
Is tristearin safe while breastfeeding?
No data indicating reproductive or lactation hazards; tristarin is a high‑molecular‑weight triglyceride with low systemic toxicity and no demonstrated mechanisms for transfer to breast milk. No harmonised hazard, SCCS/CIR concerns, or peer‑reviewed evidence suggesting risk during breastfeeding (ECHA Annex VI, PubChem, CIR/CosIng).
Is tristearin safe for baby skin?
Hazard and mechanism: no infant‑specific reproductive/toxic mechanism identified. Exposure: adult topical absorption is negligible for large triglycerides, but because infant skin has an immature barrier and higher surface‑area‑to‑weight ratio, practical exposure is scored one level higher (e=1). No evidence of systemic effects in infants from topical use. Sources: PubChem, CosIng/CIR, ECHA registration information (no reproductive flags).
