### Kojic Acid Dipalmitate (CAS 79725-98-7): Stable Skin-Brightening Ingredient for Advanced Cosmetic Formulations
Kojic Acid Dipalmitate, also known as **Kojic Dipalmitate**, is a high-value cosmetic raw material identified by **CAS No. 79725-98-7**. As a lipophilic derivative of kojic acid, it is widely used in brightening creams, facial serums, lotions, spot-care products, anti-aging formulations, after-sun products, and professional skincare solutions. Its main cosmetic functions include **skin conditioning, emollience, tone correction, antioxidant support, and pigmentation-care applications**.
Kojic Acid Dipalmitate is valued for its oil compatibility and formulation versatility. It may help improve the visible appearance of dullness, uneven skin tone, dark spots, freckles, sun-related discoloration, and post-blemish marks. As a kojic acid derivative, it is commonly associated with tyrosinase-related melanin regulation and is often combined with alpha-arbutin, niacinamide, tranexamic acid, vitamin C derivatives, licorice extract, and sunscreen ingredients. Its lipophilic structure can support incorporation into oil phases and emulsion systems. Formulators should evaluate purity, concentration, stability, packaging, light exposure, pH compatibility, and local cosmetic regulations.

1. **Stable Kojic Acid Derivative**
Kojic Acid Dipalmitate is a lipophilic ester derivative of kojic acid, widely used in cosmetic and personal-care formulations. The palmitate groups improve its oil compatibility and formulation versatility, allowing it to be incorporated more easily into creams, lotions, balms, emulsions, and anhydrous products. It is typically supplied as a white to off-white solid powder.
2. **Skin-Brightening Function**
Its primary cosmetic application is skin brightening and tone correction. Kojic Acid Dipalmitate is used in products designed to improve the appearance of dullness, uneven skin tone, sun spots, freckles, and post-blemish discoloration. Regular use may help create a more radiant and uniform-looking complexion when combined with appropriate skincare and sun protection.
3. **Tyrosinase-Related Activity**
Kojic acid derivatives are commonly used for their ability to help regulate tyrosinase, an enzyme involved in melanin formation. By supporting the control of excess pigment production, Kojic Acid Dipalmitate may help reduce the visible appearance of hyperpigmentation over time. It is often included in targeted spot-care products, brightening serums, facial creams, and professional skincare formulas.
4. **Antioxidant and Skin-Conditioning Support**
Kojic Acid Dipalmitate may provide antioxidant-related benefits in cosmetic formulations, helping support the skin against oxidative stress caused by environmental factors. It also contributes to skin conditioning and can be used in products intended to improve the overall smoothness, softness, and healthy appearance of the skin.
5. **Formulation Advantages**
Compared with unmodified kojic acid, its oil-soluble character can provide better compatibility with oil phases and emulsions. It is suitable for facial and body care, anti-aging preparations, after-sun products, and tone-correcting cosmetics. Formulators should evaluate concentration, pH, oxidation stability, packaging, light exposure, and compatibility with other active ingredients.
6. **Quality and Regulatory Considerations**
Commercial material should be verified for identity, purity, residual solvents, microbial quality, and stability. The EU CosIng database lists Kojic Dipalmitate as a skin-conditioning and emollient ingredient. Cosmetic claims must be supported by appropriate testing, and final use levels should comply with the regulations of the target market.
