Ascorbyl Tetraisopalmitate (Oil Soluble Vitamin C Derivative)

Ascorbyl Tetraisopalmitate

Oil-Soluble Vitamin C Derivative for Antioxidant & Radiance Support

INCI Name: Ascorbyl Tetraisopalmitate

Appearance: Pale yellow oily liquid

Solubility: Oil-soluble

Recommended Usage: 0.5% – 3.0%

Primary Functions: Antioxidant, skin tone support, formulation stabilizer

Ascorbyl Tetraisopalmitate is a highly stable, oil-soluble derivative of vitamin C designed for use in lipid-rich and emulsified cosmetic systems. It provides antioxidant protection and supports a brighter, more even-looking complexion with significantly lower irritation potential than water-soluble ascorbic acid.

Its oil affinity allows efficient integration into facial oils, serums, and emulsions, making it especially suitable for sensitive-skin and long-wear formulations.

Performance & Formulation Notes

Unlike L-ascorbic acid, Ascorbyl Tetraisopalmitate remains stable in oil systems and across a wide pH range, allowing greater formulation flexibility and improved shelf stability. It is commonly selected when gentle, sustained antioxidant activity is desired.

Key Benefits

• Oil-soluble vitamin C derivative with excellent formulation stability
• Supports visible radiance and skin tone uniformity
• Lower irritation potential than free ascorbic acid
• Compatible with sensitive and barrier-focused formulas
• Provides antioxidant support in sun-exposed products

Formulation Guidance

• Use phase: Oil phase
• Typical use: 0.5% – 3.0% (higher levels require solubility and stability testing)
• pH compatibility: 4 – 8
• Processing: Add during oil phase heating or cool-down with sufficient mixing
• Compatibility: Works well with esters, triglycerides, silicones, and emulsifier systems

Often paired with tocopherols to enhance oxidative stability of oils and support overall antioxidant performance in leave-on skincare.
