Kojic acid dipalmitate is used as a cosmetic whitening additive, which is more effectively absorbed by the skin while giving the skin a good moisturizing effect.Kojic acid dipalmitate (CAS 79725-98-7) is a fat-soluble derivative of kojic acid with the molecular formula C₃₈H₆₆O₆. It appears as a white crystalline powder, insoluble in water but soluble in oils, and stable across pH 3–10 (resistant to heat, light, and oxidation). Its core function is inhibiting tyrosinase to block melanin synthesis, acting as a safe, skin-absorbable whitening agent in cosmetics (creams, serums, 1–3% dosage). It also serves as a preservative/antioxidant in foods and a raw material in pharmaceuticals, with low irritation when used as directed.

Stability: It has good chemical stability. It will not turn yellow easily due to oxidation, metal ions, light, and heat, and is stable in the pH range of 3-10.
Kojic acid dipalmitate can inhibit the activity of tyrosinase, an enzyme involved in melanin synthesis. By suppressing tyrosinase activity, it can effectively prevent the formation of melanin, thus achieving the effect of skin whitening, and is more effective than kojic acid in this regard.
Cosmetic Field: It is mainly used as a whitening additive in cosmetics. As a fat-soluble active ingredient, it is more easily absorbed by the skin and can also provide good moisturizing effects. It is compatible with a wide range of cosmetic ingredients and is suitable for use in various skin care products such as creams, lotions, and serums. The recommended dosage is usually 1%-3% of the total amount.
Food Field: In the food industry, kojic acid dipalmitate is mainly used as a preservative and antioxidant, which can be used in dairy products, food oils, seasonings, candies, frozen foods, etc., to extend the product's shelf life and prevent oil oxidation and rancidity.
Other Fields: In the medical field, it is used as an important material for cephalosporin antibiotics. In addition, it can also be used as an iron analytical reagent and film spotting agent in other fields.
Generally, when used within the recommended dosage range, kojic acid dipalmitate is relatively safe. However, for individuals with sensitive skin, it is recommended to conduct a skin test before use to avoid potential allergic reactions.
Kojic acid dipalmitate is classified as an emollient, preparations containing kojic acid dipalmitate are said to inhibit UV-induced erythema.
