About

Altrenogest is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Altrenogest is a synthetic steroidal progestogen with potent hormonal activity. In the EU, substances with endocrine-disrupting properties are subject to strict regulation under Regulation (EC) No 1223/2009; altrenogest is not listed as permitted for cosmetic use and would be considered a prohibited substance due to its hormonal activity. It is classified as a potential endocrine disruptor.

Known concerns

  • Endocrine-disrupting activity
  • Not permitted in EU cosmetic products
  • Reproductive toxicity concern
  • Teratogenic potential
