What Is Kojic Acid Dipalmitate Powder?
Kojic acid dipalmitate is a lipid-soluble derivative of kojic acid. Through an esterification reaction between kojic acid and palmitic acid, we get kojic acid dipalmitate.
Kojic acid dipalmitate powder exhibits excellent formulation compatibility. Now, it has been widely used in cosmetics and personal care products, especially for skin lightening and antioxidant properties.
Applications of Sunjoy Kojic Acid Dipalmitate Powder
Kojic acid dipalmitate is an active ingredient commonly used in cosmetics. It is used to develop skin care products that improve dullness, enhance skin brightness, and even skin color, such as skin-brightening serums, creams, etc. The application focus lies in skin tone management.
Our kojic acid dipalmitate powder can also be used in dark spot management. It can be used in formulations targeted at dark spots, age spots, uneven pigmentation, and post-blemish marks. Common final products include spot treatment creams, corrective serums, and pigmentation care products targeted at pigmentation.
The oil solubility, good formulation compatibility, and stable performance enable our products’ application in facial care. Actually, facial skincare is one of the main applications of kojic acid dipalmitate powder. You can add Sunjoy kojic acid dipalmitate powder to various facial products, including facial creams, lotions, and essence products.
In addition to facial care and skin color management, Sunjoy kojic acid dipalmitate powder can also be used in products caring for other body parts, such as the body and hands. You can use our products in body lotion, hand cream, exfoliating products, and cleaning products like soaps.

Raw Material Preparation: Before manufacturing, we strictly control the quality of kojic acid and palmitic acid, the key raw materials used for producing kojic acid dipalmitate. Quality testing specifications include raw material identification, purity, moisture content, and impurity level control.
Esterification Reaction: Through chemical reactions, we add palmitic acid into the molecular structure of kojic acid, forming kojic acid dipalmitate with higher lipid solubility. During the esterification reaction, we control the temperature, time, and conditions to promote complete reaction and minimize byproduct formation.
Purification Process: After the esterification reaction, we purify the reaction products to remove unreacted residues, byproducts, and other impurities. The purification technologies commonly include solvent treatment, filtration, washing, and refining. Thus, we enhance the kojic acid dipalmitate powder purity to meet the cosmetic grade.
Drying Process: The drying process is required to minimize the moisture concentration. We conduct vacuum drying to evaporate solvents at a lower temperature, avoiding a long-term high-temperature process. Thus, we help maintain the product’s chemical stability, reduce residual solvents, and produce a stable kojic acid dipalmitate powder.
Milling and Screening: The dried kojic acid dipalmitate powder undergoes grinding and screening processes to meet the powder specification. Common machines include mechanical mills, pin mills, and hammer mills. Milling and screening can optimize powder uniformity and dispersion efficiency for stable performance during cosmetic processing.
Quality Testing: Before our products leave the factory, we conduct multiple quality tests to ensure that our kojic acid dipalmitate meets regulatory requirements for export and import. Common testing parameters include HPLC assay, purity, moisture, residue, and appearance check.

Kojic acid dipalmitate powder is a lipid-soluble kojic acid derivative. It has advanced compatibility with oil phases. However, it is in solid powder form. In cosmetic formulation development, therefore, dissolution is required to disperse kojic acid dipalmitate powder into the oil phase system.
Choose Appropriate Oil-Based Solvent
Based on your final products and their forms, you can choose different oil phases. Commonly, oil solvents with good solubility, pleasant skin feel, and high stability are recommended. You can consider caprylic or capric triglyceride, ethylhexyl palmitate, and isopropyl myristate. Other cosmetic oils or emollients, like shea butter, are also suitable.
Heat Oil-Based Solvent
To accelerate the dispersion of kojic acid dipalmitate powder, heating is recommended. When oil-phase ingredients are put into the mixing tank, you can slowly heat the solvent. The heating temperature is about 70-80℃.
During the heating, kojic acid dipalmitate powder is added while stirring. Temperature control and maintenance are important for powder dispersion acceleration. Common stirring technologies include mechanical stirring, high-shear mixing, and homogenization.
Integrate with Emulsion Systems
If your final products are in the form of cream, lotion, or emulsion-based serum, the oil solvent of kojic acid dipalmitate needs to be emulsified with the aqueous phase. High-shear mixing and homogenization are conducted for subsequent cosmetic product manufacturing.

| Commercial compatibility | Suitable for large-scale skincare product development and long-term supply | Commonly used for specialty or regulated products |
| Costs | Higher | Lower |
These two ingredients can both be used in skin-brightening formulas. However, kojic acid dipalmitate is more stable in processing and has a wider application range. Besides, in some regions, hydroquinone is strictly regulated in processing and cosmetic uses. So, if you are hesitating about the choice of cosmetic ingredients, kojic acid dipalmitate powder is more suitable.

Support Pigmentation Care
Tyrosinase is a key enzyme involved in melanin formation. In formulations, kojic acid dipalmitate powder may help regulate tyrosinase activity, thereby supporting balanced melanin production. Therefore, kojic acid dipalmitate powder is used in some pigmentation care products.
You can also combine kojic acid dipalmitate with other brightening ingredients, such as N-acetyl glucosamine (NAG), to develop multifunctional skin-brightening formulations.
Antioxidant Support
Oxidative stress is associated with skin aging and uneven skin tone. Kojic acid dipalmitate exhibits certain antioxidant properties. In related products, it may help reduce oxidative stress on the skin, thus helping maintain a balanced skin color.
Skin-Conditioning Function
Kojic acid dipalmitate is more stable. So, the formulation design is more flexible. In formulation development, you can combine kojic acid dipalmitate powder with moisturizers and soothing ingredients. Thus, you can design more gentle skincare products suitable for various skin types.
These side effects are for reference only. If you need more detailed advice on formulation design, please consult professionals.
Potential Skin Sensitivity
Kojic acid dipalmitate powder is generally considered a well-tolerated cosmetic ingredient when used at appropriate concentrations in cosmetic formulations. However, different skin types may have different reactions to cosmetic ingredients.
Some improperly designed products may cause temporary discomfort, such as mild redness, skin discomfort, and skin sensitivity.
Allergic Reaction
Some people may be allergic to kojic acid dipalmitate or other ingredients in cosmetic products. So it is recommended to conduct skin compatibility testing and patch testing in formulation development.
Factors Affecting Formulation Tolerance
The application effects and use experience are affected by different factors:
- Concentration
- Formulation pH
- Compatibility with other active ingredients
- Product dosage forms, etc.
Proper formulation design can reduce possible skin uneasiness.
