1. Fördelar med Kojic Acid Dipalmitate:
* Övervinna instabiliteten hos kojinsyra på ljus och värme och missfärgning av metalljoner.
* På grund av frånvaron av en grupp i sin molekylstruktur bildar den inte vätebindningar med konserveringsmedel, solskyddsmedel eller andra aktiva ingredienser i kosmetiska system, vilket påverkar effektiviteten hos dessa tillsatser och har utmärkta sammansättningsegenskaper.
* God fettlöslighet, bättre absorberad av huden.
