Kojic Acid Dipalmitate is a stable, oil-soluble ester of kojic acid that provides the same brightening effects as kojic acid but with better stability, particularly in anhydrous and oil-based formulations.
It is commonly used in skin-brightening products, especially in formulations like oils, balms, and serums, where stability and ease of incorporation are key.
Kojic Acid Dipalmitate works by inhibiting melanin production, thus helping to reduce dark spots, hyperpigmentation, and uneven skin tone over time.
Its ester form makes it more suitable for use in emulsions and oil-based systems, avoiding the stability concerns seen with free kojic acid.
FEATURES
- Stable form – more stable than free kojic acid, especially in oil-based and anhydrous systems.
- Brightening support – helps reduce hyperpigmentation and dark spots for a more even skin tone.
- Oil-soluble – ideal for incorporation into oil-based formulations like serums and facial oils.
- Gentler on skin – less irritation potential compared to free kojic acid.
BEST FOR
- Brightening serums
- Skin-lightening oils
- Face creams
- Balms
- Hyperpigmentation treatments
- Dark spot correctors
FORMULATION GUIDELINES
| INCI | Kojic Acid Dipalmitate |
|---|---|
| Type | Oil-soluble ester of Kojic Acid (brightening agent) |
| Solubility | Oil soluble |
| Use Rate | 0.5–2.0% typical. 1.0–1.5% is common for effective skin-lightening effects. |
| Best Phase | Oil phase (mix with other oils or emulsifiers) |
| pH Compatibility | Works best in slightly acidic to neutral formulations (pH 5.0–7.0). |
| Temperature Tolerance | Stable under normal processing. We recommend adding below 70°C in an oil-based system or emulsions to preserve the ingredient’s efficacy. |
| Pro Tip | Add Kojic Acid Dipalmitate into the oil phase for even distribution, then mix thoroughly before emulsifying or adding other actives. It’s highly stable in oil formulations, but it’s still important to package the formula with air-tight, opaque containers to minimize exposure to light and air. Combining it with other brighteners like alpha-arbutin, niacinamide, or vitamin C can help create a powerful skin-lightening regimen. |
| Appearance | White to off-white solid or waxy solid (solid at room temperature, melts upon heating) |
| Stability Notes | More stable than free kojic acid. Ensure proper storage to maintain stability over time. |
| Storage | Store in a cool, dry place, away from light and heat to prevent degradation. |
