Kojic Acid Dipalmitate (KAD)
CAS No. 79725-98-7
Kojic Acid Dipalmitate (KAD) is a diesterified derivative of Kojic Acid. It is considered to be superior to Kojic Acid in its whitening ability and is more stable than Kojic Acid in cosmetic formulations.
By inhibiting tyrosinase activity, Kojic Acid Dipalmitate is capable of suppressing skin pigmentation. Its ability to suppress melanin formation makes it effective in whitening dark skin, or areas of dark skin. Its effects have been boosted when used in combination with glucosamine derivatives like N-Acetyl Glucosamine (NAG).
Kojic Acid Dipalmitate has good stability in heat and light, with no color change.
- Stable from pH 3 to 10
- Does not complex with metal ions and will not change color
- Light and heat stable
- Compatible with most cosmetic ingredients.
- Sunscreens and after-sun products
- Makeup products
- Skin lightening products
- Anti-aging products
- Creams and lotions
INCI: Kojic Acid Dipalmitate
Kojic Acid Dipalmitate (KAD) can tend to form a crystal precipitate in some cosmetic formulations. It is recommended to add Isopropyl Palmitate or Isopropyl Myristate to the oil phase containing KAD and heat to 80°C (167°F) and hold for 5 minutes until the KAD dissolves completely. Then add the oil phase to the aqueous phase and emulsify for about 10 minutes.
Typical usage rate: 1 - 5%, typically 3-5% in whitening products
Appearance: White to almost white crystalline powder
Solubility: Insoluble in water, soluble in oil
