About

A selenium-enriched yeast ferment restricted under EU Annex II/297 due to selenium's toxicity at elevated doses; selenium compounds are tightly regulated in cosmetics and this ferment cannot be used in EU cosmetic products.

Saccharomyces/Selenium Ferment is restricted under EU Regulation 1223/2009 Annex II/297, which specifically prohibits selenium and its compounds in cosmetic products. Selenium is an essential trace element but has well-documented toxicity at doses only slightly above nutritional requirements. The narrow margin between essential and toxic doses makes selenium a substance of concern in cosmetic formulations. This restriction means the ingredient cannot be legally used in cosmetic products placed on the EU market, regardless of the fermentation form or perceived bioavailability.

Known concerns

  • Listed in EU Annex II (prohibited substances)
  • Selenium has narrow margin of safety between essential and toxic doses
  • Prohibited for cosmetic use in the EU
  • Renal and neurological toxicity at elevated doses
