FERROUS GLUCONATE.

Valuable CAS 299-29-6 / SKIN CONDITIONING

Ferrous Gluconate, a bioavailable iron salt, functions as a cellular energizer in precision skincare. It actively enhances metabolic processes within skin cells, contributing to improved vitality, firmness, and luminosity. Additionally, it serves as a valuable stabilizing agent in cosmetic formulations.

Skin Conditioning Cellular Energizer Firming Elasticity Enhancer Radiance Booster Stabilizer

Science

Mechanism of Action

This ingredient significantly boosts the skin's cellular energy metabolism by enhancing glucose consumption and ATP (adenosine triphosphate) production. This increased cellular energy supports the synthesis of the extracellular matrix, which is vital for skin structure. It also promotes cell proliferation and migration, essential processes for skin regeneration and repair. Beyond its direct skin benefits, Ferrous Gluconate helps stabilize cosmetic formulations, preventing degradation of other ingredients.

Stability

Ferrous Gluconate is sensitive to light and air, with ferrous iron gradually oxidizing to ferric. This oxidation process is particularly rapid in approximately neutral solutions. Stability is significantly enhanced by buffering the solution to an optimal pH range of 3.5 to 4.5, ideally with citrate. Aqueous solutions can also be stabilized with the addition of glucose, and glycerin is known to retard oxidation. Solution color varies with pH: light yellow at pH 2, brown at pH 4.5, and green at pH 7, with rapid oxidation occurring at higher pH levels.

Synergies

Conflicts

  • Ascorbic acid (causes dark coloration)
  • Aminoacetic acid (causes dark coloration)
  • Pyridoxine (produces green color)
  • Soluble carbonates (cause precipitation in neutral solutions)
  • Phosphates (cause precipitation in neutral solutions)
  • Oxalates (cause precipitation in neutral solutions)

Safety

Safety Profile

CIR Status
Not reviewed
Max tested
10%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) has not specifically evaluated Ferrous Gluconate for cosmetic use. However, the FDA classifies it as 'Generally Recognized As Safe' (GRAS) for use as a nutrient supplement in food. Toxicological data indicates it is a low-toxicity substance, with an oral LD₅₀ in rats of 2237 mg/kg. The EWG Skin Deep database rates it 'LOW' for concerns including cancer, allergies & immunotoxicity, and developmental and reproductive toxicity. While a patent application suggests cosmetic concentrations up to 10%, this is not a safety assessment-derived maximum concentration from regulatory bodies.
