Basic Properties

• Appearance: It is a white crystalline powder.

• Melting Point: The melting point ranges from 92℃ to 96℃.

• Solubility: It is insoluble in water, but soluble in oil and propylene glycol.

• 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.

Whitening Mechanism

• 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.

Main Applications

• 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.

Safety Profile

• 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.
