A steroid hormone with estrogenic activity, typically derived from animal sources, and subject to significant regulatory restrictions.
Estratetraenol (estra-1,3,5(10),6-tetraen-3-ol) is a weak estrogenic steroid. It is not listed in EU CosIng for cosmetic use and is considered a substance of concern due to its hormonal activity. Under EU Cosmetics Regulation (EC) No 1223/2009, substances with endocrine-disrupting properties are subject to restriction, and estratetraenol would require evaluation before cosmetic use. It is not permitted as a cosmetic ingredient in the EU without specific authorization.
Known concerns
- Endocrine-disrupting potential — hormonal activity
- Not authorized for cosmetic use in the EU without evaluation
- Source and purity concerns (typically animal-derived)
