Kojic dipalmitate is a derivative of kojic acid, where the two hydroxyl groups of kojic acid are replaced with palmitic acid. The chemical name is 2-palmitoyloxymethyl-5-palmitoyloxy-γ-pyrone.
Physical Form:
Kojic dipalmitate is typically found as a white to pale yellow crystalline powder.
Function and Uses:
Skin Lightening: Similar to kojic acid, kojic dipalmitate is known for its skin-lightening properties. It inhibits melanin production, making it effective in addressing hyperpigmentation, dark spots, and uneven skin tone.
Stability: Kojic dipalmitate is often chosen for its stability in formulations, particularly in comparison to kojic acid. It is less prone to oxidation and discoloration.
Skin Penetration: Kojic dipalmitate is believed to penetrate the skin more easily than kojic acid, potentially enhancing its effectiveness.
Common Applications:
Kojic dipalmitate is commonly used as an active ingredient in skincare products such as creams, lotions, serums, and soaps. It is often included in formulations targeting hyperpigmentation and promoting skin brightening.
Benefits:
Hyperpigmentation Treatment: Kojic dipalmitate helps in treating various forms of hyperpigmentation, contributing to a more even skin tone.
Stable Formulation: Its stability makes it suitable for formulations that require a longer shelf life, as it is less prone to color changes and degradation.
Skin Penetration: The modified structure of kojic dipalmitate is believed to enhance its penetration into the skin, potentially improving its efficacy.
Considerations:
While kojic dipalmitate is considered a stable alternative to kojic acid, some individuals may still experience skin sensitivity or irritation. Patch testing is advisable.
Regulatory Status:
Kojic dipalmitate is generally recognized as safe for use in cosmetics when formulated according to regulatory guidelines. However, regulatory status may vary depending on the country or region.
Usage Instructions:
Kojic dipalmitate is typically incorporated into skincare formulations at concentrations ranging from 1% to 3%, depending on the specific product and its intended use.
As with any skincare ingredient, it's recommended to follow product instructions and perform patch tests, especially for individuals with sensitive skin.
