Kojic acid dipalmitate
Kojic acid dipalmitate (79725-98-7), alias kojic acid dipalmitate, Kojic acid palmitate, etc.,
English name is Kojic acid dipalmitate. Its chemical names are 2-palmitoyl methyl-5-palmitoyl - pyranone,
2-palmitoyl methyl-5-palmitoyl - gamma-pyranone. The character is like white flake crystal.
Kojic acid dipalmitate is a kind of efficient whitening agent,
which can effectively inhibit the activity of tyrosinase and block or delay the formation of melanin.
It has a strong inhibitory effect on the production of melanin in human skin, and binds with copper ions in inhibiting tyrosinase activity,
preventing the activation of copper ions and tyrosinase. It can also inhibit the dark spots and freckles generated by mala pigment,
promote the metabolism of the skin, quickly eliminate the mala pigment that has been formed, and see the whitening effect in the short term.

Main Function of Kojic acid dipalmitate
Kojic acid dipalmitate is a modified kojic acid derivative that has the following effects:
1.Whitening effect:
Kojic acid dipalmitate is more effective than kojic acid to inhibit the activity of tyrosinase in the skin,
thus inhibiting the formation of melanin, and has a good effect on whitening skin and sun protection.
2.Freckle effect:
Kojic acid dipalmitate can improve skin pigmentation, against age spots, stretch marks, freckles and general pigmentation.
3.Good moisturizing effect:
As a fat-soluble additive in cosmetics, kojic acid dipalmitate is not only easier to formulate,
but also more effectively absorbed by the skin, giving the skin a good moisturizing effect
4.Improved skin absorption:
Due to the fat-soluble properties of kojic acid dipalmitate, it can be absorbed by the skin more effectively,
while giving the skin a good moisturizing effect
5.Stability:
Kojic acid dipalmitate overcomes the instability of kojic acid to light, heat and metal ions,
and because there is no hydroxyl group in its molecular structure, it will not form hydrogen bonds with preservatives,
sunscreen or other active ingredients in the cosmetic system and affect the efficacy of these additives
6.Formulation convenience:
Kojic acid dipalmitate as a fat-soluble whitening active agent, in addition to easier formulation,
can be more effectively absorbed by the skin
In summary, kojic acid dipalmitate is an efficient and stable whitening active agent,
which is widely used in the cosmetics industry to achieve skin whitening and moisturizing effects.
Application of Kojic acid dipalmitate
Kojic acid dipalmitate is mainly used as cosmetic whitening additive.
When used, it is added to the oil phase for use, and the amount is 1~3% of the total. When using,
it should be noted that it dissolves in the oil phase and participates in the dissolution at 68 ° C,
which should be emulsified at a higher temperature, otherwise there will be crystallization.
Use PH range 5.0 ~ 8.0; It is recommended to add oil-soluble antioxidants.
Storage should be cool, closed and away from light .
