1. Vantaggi del dipalmitato dell'acido kojico:
* Superare l'instabilità dell'acido kojico sulla luce e sul calore e lo scolorimento degli ioni metallici.
* A causa dell'assenza di un gruppo nella sua struttura molecolare, non forma legami idrogeno con conservanti, creme solari o altri ingredienti attivi nei sistemi cosmetici, influenzando l'efficacia di questi additivi e ha eccellenti proprietà composti.
* Solubilità grassa buona, meglio assorbita dalla pelle.
