    Kojic Acid Dipalmitate CAS 79725-98-7

    Kojic Acid Dipalmitate (CAS 79725-98-7) is a highly stable, oil-soluble derivative of Kojic Acid utilizing its modified ester structure to provide superior skin whitening efficacy without the oxidation issues of the parent compound. Chemically identified as the diester of Kojic Acid and Palmitic Acid, this white crystalline powder functions as a potent tyrosinase inhibitor, effectively blocking melanin formation to treat hyperpigmentation, age spots, and melasma. Unlike pure Kojic Acid, KAD is resistant to light, heat, and metallic ions, preventing color changes in formulations. As a lipophilic Cosmetic active, it is extensively integrated into high-end brightening creams, lotions, and sun-repair products due to its excellent skin permeability and moisturizing properties. We ensure bulk supply capabilities for this material, providing access to competitive factory pricing and customized specifications to meet specific melting point and color standards. Full technical documentation, including MSDS, TDS, COA, is available to support compliance and safety protocols.

    Product Description

    Kojic Acid Dipalmitate (KAD) is a modified ester derivative of Kojic Acid. It overcomes the instability of Kojic Acid to light, heat, and metal ions, and keeps the inhibitory activity of tyrosinase and prevents the forming of melanin.

    As a fat-soluble skin whitening agent, it is easier to be absorbed by the skin compared to water-soluble acids. It is compatible with almost all kinds of preservatives and sunscreens, making it a versatile ingredient for various cosmetic formulations.

    Key Benefits:

    1. Skin Lightening: Effectively inhibits tyrosinase activity.
    2. Stability: Chemically stable, does not change color over time compared to pure Kojic Acid.
    3. Solubility: Oil-soluble, making it easy to formulate into creams and lotions.

    FAQ - Technical & Supply Chain

    • Q:

      How does Kojic Acid Dipalmitate CAS 79725-98-7 compare to standard Kojic Acid?

      A: Kojic Acid Dipalmitate (CAS 79725-98-7) overcomes the instability of pure Kojic Acid; it is oil-soluble (facilitating skin absorption) and does not oxidize or turn brown upon exposure to light, heat, or metal ions, ensuring a longer shelf life for the final cosmetic product.
    • Q:

      Is this ingredient effective for skin lightening formulations?

      A: Yes, this material is typically applied as a primary whitening active because it inhibits tyrosinase activity more effectively than Kojic Acid in actual use due to its enhanced penetration into the skin layers and compatibility with other oil-phase ingredients.
