Detailed Analysis
Ferric Glycerophosphate (CAS 38455-91-3, PubChem CID 14208876) is the iron(III) salt of glycerophosphoric acid. It functions as an astringent in cosmetics, helping to tighten skin and reduce the appearance of pores. Iron glycerophosphate is also used as a nutritional supplement, suggesting reasonable oral and dermal safety. The ferric (Fe³⁺) form is more stable and less reactive than ferrous (Fe²⁺) iron. No GHS hazards are listed. Care must be taken to avoid excessive iron levels which could promote oxidative stress.
