1. Product Overview
Kojic Dipalmitate (KDP) is a modified, highly stable derivative of kojic acid. While traditional kojic acid is known for inhibiting tyrosinase activity and reducing melanin production, it is often prone to chemical instability and discoloration when exposed to light, heat, or metal ions. By esterifying kojic acid with palmitic acid, Kojic Dipalmitate achieves superior thermal, light, and pH stability while maintaining high efficacy. Furthermore, its lipophilic nature allows it to penetrate the epidermal skin layers much more efficiently than standard kojic acid.
Our premium Kojic Dipalmitate Powder is manufactured to a high purity standard of not less than 98.0 percent, verified through strict HPLC analysis. For B2B cosmetic formulators, skincare brands, and contract manufacturers, our bulk KDP delivers exceptional batch-to-batch consistency, excellent oil solubility, and reliable performance across whitening creams, lotions, serums, and anti-aging emulsions.

3. Functional Applications
- Skin Brightening & Pigmentation Correction: Inhibits tyrosinase activity to effectively reduce age spots, freckles, and hyperpigmentation for a balanced skin tone.
- Superior Formulation Stability: Unlike regular kojic acid, KDP does not turn yellow when exposed to air, light, or metal ions, ensuring long shelf life.
- Enhanced Dermal Penetration: The lipophilic ester structure enables easier absorption through the skin lipid barrier for heightened bio-efficacy.
- Antioxidant & Anti-Aging Support: Helps protect dermal cells from oxidative stress and environmental triggers associated with premature aging.
4. Formulation Combinations
To create synergistic, high-performance cosmetic profiles, Kojic Dipalmitate pairs exceptionally well with:
- Alpha-Arbutin & Niacinamide: Combines multi-pathway tyrosinase inhibitors for powerful, comprehensive skin brightening and tone correction.
- Vitamin C (Ascorbyl Tetraisopalmitate) & Vitamin E: Provides an oil-soluble antioxidant matrix that protects formula integrity and enhances skin radiance.
- Hyaluronic Acid: Balances active treatment serums with deep epidermal hydration and soothing moisture retention.
5. Market Opportunities
- Growing Demand for Stable Skin Brighteners: Global consumer preference for high-efficacy, non-irritating, and photostable active ingredients in skincare.
- Advanced Cosmetic Formulations: Skincare brands increasingly prefer oil-soluble kojic dipalmitate over unstable water-soluble alternatives for emulsion systems.
- Anti-Aging & Hyperpigmentation Lines: Expanding applications in premium facial creams, spot correctors, and luxury body lotions.
6. Quality & Supply
- Rigorous Analytical Testing: Verified via high-performance liquid chromatography (HPLC); every commercial lot ships with a detailed, lot-specific Certificate of Analysis (CoA).
- Packaging & Storage: Packaged in food-grade aluminum foil bags or double-lined fiber drums (1kg/bag, 25kg/drum). Store tightly sealed in a cool, dry place away from direct light and moisture.
- Global Compliance: Manufactured under strict cGMP and ISO quality management frameworks, meeting international cosmetic raw material export regulations.
7. FAQ (Frequently Asked Questions)
Q1: What is the main advantage of Kojic Dipalmitate over regular Kojic Acid?
A1: Kojic Dipalmitate is far more stable against light, heat, and metal ions, preventing the unwanted yellow discoloration commonly seen in regular kojic acid formulas. It also offers better skin penetration due to its oil-soluble structure.
Q2: How should Kojic Dipalmitate be incorporated into cosmetic formulas?
A2: Because KDP is fat-soluble, it should typically be added to the oil phase of an emulsion and heated to around 70 to 80 degrees Celsius until completely dissolved.
Q3: What are the typical use levels in finished cosmetic products?
A3: Standard usage levels in finished cosmetic formulations typically range from 1.0% to 5.0%, depending on the desired product efficacy.
