Kojic Acid Dipalmitate (CAS 79725-43-8)

Application and positioning

Kojic acid esterified with two palmitic acids: the ester is oil-soluble, more stable to light and less irritating than kojic acid itself. Used in emulsions and creams for the appearance of uneven skin tone. Laurand supplies it from audited Chinese producers in kilogram to multi-hundred-kilogram lots, with the purity and microbiological documentation cosmetic formulators require.
