Kojic Acid Dipalmitate is a lipid-soluble derivative of kojic acid, created by esterifying kojic acid with palmitic acid. This structural modification addresses the two major limitations of free kojic acid: poor stability (oxidation, discoloration) et poor skin penetration (hydrophilic) .
Key differentiator: Kojic Acid Dipalmitate is the most stable and skin-bioavailable form of kojic acid, delivering superior brightening efficacy with no formulation discoloration (unlike free kojic acid which turns yellow/brown over time).
Why the market has shifted:
| Paramètre | Kojic Acid | Kojic Acid Dipalmitate |
|---|---|---|
| Solubilité | Water-soluble | Oil-soluble |
| Stability (color) | Unstable (oxidizes yellow→brown) | Stable (no discoloration) |
| Stability (heat) | Degrades >50°C | Stable >80°C |
| Skin penetration | Poor (hydrophilic) | Excellent (lipophilic) |
| Tyrosinase inhibition | Potent (direct) | Potent (after enzymatic hydrolysis) |
| Sustained release | No (rapid) | Yes (gradual release of active kojic acid) |
| Formulation pH | Narrow (4–6) | Broad (4–8) |
| Shelf life | 12–18 months | 36 mois |
| Discoloration risk | High (browning) | None |
| Irritation potential | Moderate (high dose) | Low (gradual release) |
| Application | Typical Usage | Principaux arguments |
|---|---|---|
| Melasma treatment creams | 1–2% | Reduces dark patches, even skin tone |
| Dark spot correctors | 1–2% | Fades age spots, sun spots, post-acne marks |
| Brightening serums | 0.5–1.5% | Illuminates, evens complexion |
| All-over body lotions | 0.5–1% | Even skin tone on arms, legs, décolletage |
| Application | Typical Usage | Positioning |

Q: What is the difference between Kojic Acid and Kojic Acid Dipalmitate?
A: Kojic Acid Dipalmitate is the oil-soluble, stabilized ester of kojic acid. It is more stable (no discoloration), better penetrating, and easier to formulate than free kojic acid. It hydrolyzes on skin to release active kojic acid.
Q: Is Kojic Acid Dipalmitate more effective than Kojic Acid?
A: Yes, in finished formulations. Although free kojic acid has higher in vitro tyrosinase inhibition, its poor stability and penetration limit real-world efficacy. Kojic Acid Dipalmitate delivers more active kojic acid to melanocytes due to better penetration and stability.
Q: Does Kojic Acid Dipalmitate cause skin irritation?
A: No. It is non-irritating at recommended concentrations (0.5–2.0%). The gradual release of kojic acid reduces irritation potential compared to free kojic acid.
Q: Can Kojic Acid Dipalmitate be used during pregnancy?
A: Yes. Unlike hydroquinone, kojic acid derivatives have no known teratogenic risk. However, consult a physician before use.
Q: How should Kojic Acid Dipalmitate be stored?
A: Cool, dry, sealed, protected from light. Shelf life: 36 months.
Q: Is Kojic Acid Dipalmitate soluble in water?
A: No. It is oil-soluble. For water-based serums, use solubilizers or emulsify.
