What is Kojic Acid Dipalmitate CAS 79725-98-7?

Kojic Acid Dipalmitate CAS 79725-98-7 is a diester derivative of kojic acid, with the molecular formula C38H66O6. It is an oil-soluble cosmetic active used mainly in skin-brightening formulations.

How does it differ from standard Kojic Acid?

The two active hydroxyl groups are esterified with palmitic acid, making the molecule more lipophilic and less prone to oxidation, color change and metal-ion complexation than kojic acid. This gives better compatibility with oils, esters, sunscreens and preservatives.

How does Kojic Acid Dipalmitate work in skin-lightening products?

It inhibits tyrosinase and helps reduce melanin formation. In cosmetic use it is intended for creams, lotions, serums and other leave-on formulas targeting uneven tone, dark spots or hyperpigmentation.

What are the key quality parameters?

Common specifications are white to off-white crystalline powder, HPLC assay at least 99%, melting point 92-96 C, loss on drying, residue on ignition, controlled heavy metals and arsenic, and low color in solution.

How should Kojic Acid Dipalmitate be stored?

Store it sealed in a cool, dry place away from light and moisture. Because it is oil-soluble and heat/light stable compared with kojic acid, it should still be protected from prolonged high temperature during storage and handling.
