Sodium Phytate

Sodium Phytate is a natural chelating agent and antioxidant booster derived from rice bran, corn, or other plant seeds. It’s used in cosmetics and skincare formulations as a natural alternative to EDTA (like Disodium EDTA), helping to stabilize products and enhance preservative effectiveness.

• INCI Name: Sodium Phytate
• Source: 100% plant-based — extracted from rice bran or corn
• Appearance: White to off-white powder
• Solubility: Water-soluble
• Typical Use Level 0.05–0.2% (usually 0.1%)
• pH Range: Stable from 4–8
• Function: Chelating agent, antioxidant synergist, preservative booster

How It Works

Sodium phytate binds (chelates) metal ions such as iron (Fe³⁺), copper (Cu²⁺), and calcium (Ca²⁺) that can:

• Catalyze oxidation of oils and vitamins
• Cause color changes or rancidity
• Reduce preservative effectiveness
• By removing these trace metals, Sodium Phytate:
• Prevents oxidation of sensitive ingredients (like Vitamin C, Retinol, and plant extracts)
• Improves product stability and shelf life
• Enhances preservative performance, especially with mild or natural systems (like Sodium Benzoate, Potassium Sorbate, or Ethylhexylglycerin)

Key Benefits

✅ 100% natural and biodegradable
✅ Replaces EDTA (Disodium EDTA or Tetrasodium EDTA) in “clean beauty” formulas
✅ Boosts antioxidant systems — often paired with Ascorbic Acid, Tocopherol, or Ferulic Acid
✅ Prevents color and odor degradation in natural emulsions or serums
✅ Compatible with most emulsions, gels, and surfactant systems

Formulation Tips

• Add to water phase
• Recommended at 0.05–0.2% — higher levels can reduce metal ion availability too much and affect viscosity in some gels.
• Works synergistically with Citric Acid to optimize metal chelation.

Compatible with:

• Niacinamide
• Hyaluronic acid
• Panthenol
• Plant extracts
• Preservative blends

Stability & Storage

• Very stable under normal conditions.
• Store in cool, dry, sealed container away from direct light.
• pH-sensitive only at extremes (<4 or >9).

Typical Cosmetic Uses

• Serums: Prevent oxidation of actives (e.g., Vitamin C, Niacinamide)
• Creams & Lotions Stabilize emulsions and oils
• Shampoos & Cleansers Prevent color or fragrance degradation
• Natural formulations Substitute for EDTA
• Sunscreens Protect filters and oils from oxidation

✅ Summary

Sodium Phytate is a natural, eco-friendly chelating and stabilizing ingredient ideal for clean, minimalist formulations.
It enhances shelf life, supports antioxidants, and prevents unwanted color or odor changes — all while being gentle and biodegradable.
