Norvinisterone is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.
Norvinisterone (CAS 6795-60-4) is a synthetic anabolic steroid of the 19-norprogesterone series with both anabolic and progestogenic activity. Its classification as a hormonal anabolic steroid places it in EU Annex II of Regulation 1223/2009 as a prohibited cosmetic ingredient. No safe use level or function in cosmetic formulations has been identified, and its endocrine-disrupting potential is a primary regulatory concern.
Known concerns
- EU Annex II banned — anabolic progestogenic steroid
- Endocrine disruption risk
- No cosmetic function or safe use established
