Ascorbyl Tetraisopalmitate (Oil Soluble Vitamin C Derivative)

Why Use Ascorbyl Tetraisopalmitate?

Unlike traditional water-soluble Vitamin C derivatives, Ascorbyl Tetraisopalmitate is oil-soluble and more stable, allowing it to remain effective for longer periods in formulations. It absorbs efficiently into the skin and converts to active ascorbic acid inside cells, where it neutralizes free radicals and supports collagen production.

Key Benefits:

• Brightens dull or uneven skin tone
• Supports collagen synthesis and skin elasticity
• Reduces the appearance of fine lines and wrinkles
• Antioxidant protection from environmental stressors
• Less irritation than other Vitamin C forms — ideal for sensitive skin

Common Applications:

• Facial oils and oil serums
• Anti-aging creams and emulsions
• Brightening ampoules and booster treatments
• Sun care products (as antioxidant support)

Usage Guidelines:

• Typical usage: 7% to 10%
• Add to the oil phase of your formulation
• Compatible with most emulsifiers and esters
• Stable across a broad pH range (4–8)

Formulation Tips:

• Combine with Vitamin E for synergistic antioxidant effects
• Use alongside Ferulic Acid for improved oxidative stability
• Great addition to facial oils, balm serums, or silicone-based emulsions

Frequently Asked Questions

• What is Ascorbyl Tetraisopalmitate?
  A stable, oil-soluble derivative of Vitamin C known for strong antioxidant activity. It helps brighten skin tone, support collagen synthesis, and protect against free radical damage.
• How is it different from L-Ascorbic Acid?
  L-Ascorbic Acid is water-soluble and unstable, while Ascorbyl Tetraisopalmitate is oil-soluble and much more stable. It penetrates lipid layers effectively, causes less irritation, and offers broader formulation flexibility, though it typically works more gradually than pure Vitamin C.
• What skin types can use it?
  All skin types, including sensitive. Its lower irritation potential makes it a good option when water-based Vitamin C is too reactive.
• At what percentage should it be used?
  Generally 7%–10%. Lower levels provide antioxidant support; higher levels target brightness and firmness. Always verify compatibility with the rest of your formula.
• Can it be combined with other actives?
  Yes. It pairs well with Vitamin E and Ferulic Acid for antioxidant synergy, and works alongside Niacinamide, peptides, and botanical oils.
• What products is it best used in?
  Facial oils, oil serums, anti-aging creams, and sun care formulations where oil-soluble actives shine.
