Formulating with Kojic Acid Dipalmitate
Recently I made a cream using kojic acid dipalmitate. I incorporate the kojic dipalmitate powder together with alpha arbutin and niacinamide into a lotion and cream base. Antioxidant used is BHT, sodium metabisulfite, and vitamin E acetate. Glycerin as humectant and wetting agent for the formula.
The appearance of the cream looks good however when applied on skin, it leaves flaky residue on skin. What do I need to change in the formulation to overcome the residue?
Thank you so much.
