MANGANESE GLUCONATE.

Valuable CAS 6485-39-8 / SKIN CONDITIONING

Manganese Gluconate is a water-soluble trace mineral salt prized for its multifaceted benefits in skincare, including potent antioxidant action, support for skin barrier function, and enhancement of overall skin appearance. It plays a pivotal role in cellular protection and renewal, contributing to a more resilient and radiant complexion.

Science

Manganese Gluconate operates as a crucial cofactor for the enzyme superoxide dismutase (MnSOD), delivering robust antioxidant protection against reactive oxygen species and free radicals, which are primary drivers of premature skin aging and cellular damage. It actively contributes to skin healing and collagen synthesis by stimulating enzymes vital for collagen formation, thus fortifying the skin's structural integrity and improving elasticity. Furthermore, it aids in extracellular matrix synthesis and remodeling through the activation of prolidase, essential for collagen production, and glycosyltransferases, critical for glycosaminoglycan synthesis. The ingredient also exhibits anti-inflammatory properties, effectively calming redness, swelling, and discomfort often associated with inflammatory skin conditions. Beyond its reparative roles, it functions as a skin conditioning agent, minimizing moisture loss, promoting a smooth skin texture, boosting skin metabolism, and helping to harmonize skin tone for a natural, healthy glow.

Stability

A 5% aqueous solution of Manganese Gluconate is stable within a pH range of 5 to 7. It is slightly hygroscopic, requiring storage in a cool, dry place, shielded from direct sunlight, and in an airtight container for optimal long-term stability. The ingredient can engage in chelation interactions, potentially affecting its bioavailability and efficacy, especially with compounds like phytates. Formulators should select gel makers, cream makers, or thickeners that can tolerate electrolytes.

Synergies

  • Vitamin E
  • Other antioxidants

Conflicts

  • Phytates (due to chelation)
  • Certain gel/cream makers or thickeners sensitive to electrolytes

Safety

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Manganese Gluconate and its derivatives safe for use in cosmetics, reporting no skin or eye irritation or sensitization. A 2021 CIR safety assessment reaffirmed its safety in current cosmetic practices. The FDA classifies it as Generally Recognized As Safe (GRAS) for use as a food additive. While generally well-tolerated on the skin, GHS classification indicates it 'Causes serious eye irritation' (H319), and a patch test is recommended for individuals with highly sensitive skin, despite overall low skin irritation potential.
