High-Quality Cosmetic Grade Kojic Acid Dipalmitate 99% Bulk Wholesale Factories, Factory
Product Description
Product Description
Kojic acid dipalmitate is a fat-soluble derivative of kojic acid. It effectively overcomes kojic acid's vulnerability to light, heat, and metal-ion discoloration. Due to the absence of hydroxyl groups in its molecular structure, it does not form hydrogen bonds that compromise preservatives, sunscreens, or other active cosmetic ingredients, providing superior compounding stability. As an oil-soluble cosmetic additive, it allows for streamlined formulation and provides superior skin absorption along with notable moisturizing properties.

Kojic Acid vs Kojic Dipalmitate
Both substances serve as tyrosinase inhibitors for skin brightening and pigment reduction, yet they present distinct formulation profiles.
Water-soluble brightening active with fast action, directly inhibiting tyrosinase to stop melanin synthesis.
Limitations: Poor stability. Discolors to yellow or brown when exposed to light, heat, or metal ions. Functions within a narrow acidic pH range and may cause irritation at elevated dosages. Best suited for toners, aqueous serums, and soaps.
Oil-soluble ester derivative that circumvents discoloration and degradation problems.
Operates as a prodrug: upon skin permeation, it is hydrolyzed by esterases to continuously release active kojic acid for steady, long-lasting brightening. Features superior photostability, thermal stability, wide pH tolerance, and skin mildness. Ideal for creams, lotions, emulsions, and oil-based systems.
Functions & Applications
- Skin Lightening: Widely applied in whitening cosmetics due to its capacity to inhibit tyrosinase, the vital enzyme responsible for synthesis of melanin that gives skin its color.
- Preservation Properties: Possesses antibacterial, antifungal, and antioxidant attributes. Protects fruits against browning and preserves natural pink and red tones in seafood.
- Industry Formulations: Utilized in antibiotic synthetic intermediate items, agricultural plant protection, and specialty chemical reagents.
