About

An aluminum complex of the amino acid methionine, used in cosmetics with aluminum exposure concerns and limited safety data.

Aluminum Methionate (CAS 52667-15-9) is the aluminum salt of the amino acid methionine. PubChem safety score is 60. Aluminum compounds are subject to scrutiny under EU CosIng due to concerns about systemic aluminum accumulation. Aluminum is currently under review for potential neurotoxicity and reproductive effects. The substance does not appear on Annex II prohibition list, but Aluminum chlorides are restricted in Annex III for certain applications. The methionine component introduces nitrogen and sulfur, but the complex as a whole is not well-studied for dermal absorption. Use in leave-on products should be approached with caution.

Known concerns

  • Aluminum exposure concerns
  • Limited safety data for dermal absorption
  • Potential for systemic accumulation
