Kojic acid is a kind of specialized inhibitor for melanin. It can prevent the tyrosinase activity through synthesizing with copper ion in the cells after it enters skin cells. Kojic acid and its derivative has better inhibitory effect on tyrosinase than any other skin whitening agents. At present it is assigned into various kinds of cosmetics for curing freckles, spots on the skin of old man, pigmentation and acne.
Kojic acid can also eliminate free radical, strengthen cell activity of cell and keep the food fresh. It is widely used in the fields of medicine and food.

Kojic acid dipalmitate
Cas No.: 79725-98-7
Molecular formula: C38H66O6
Molecular weight: 618.9
Content: 98% min

Kojic acid dipalmitate is modified kojic acid derivative, which not only overcomes the instability to light, heat and metallic ion, but also keeps the inhibitory tyrosinase activity and prevents the forming of melanin.

Kojic acid dipalmitate owns stable chemical property. It will not turn yellow for oxidation, metallic ion, illumination and heating. As fat soluble skin whitening agent, it is easier to be absorbed by skin.

Kojic acid dipalmitate is applied to the cosmetics. It is modified kojic acid derivative, which not only overcomes the instability to light, heat and metallic ion, but also keeps the inhibitory tyrosinase activity and prevents the forming of melanin. As fat soluble skin whitening agent, it is easier to be absorbed by skin.

With the most advanced technology, kojic acid dipalmitate synthesized by our company has the most shallow color and the minimum impurit.

Benefits

Skin lightening	Kojic dipalmitate is more efficacious than kojic acid in inhibiting the activity of tyrosinase present in human skin so as to inhibit the melanin formation and produce excellent effects in whitening skin and in anti-suntan.
Solubility and skin absorbance	Kojic acid dipalmitate is oil soluble and is more easily absorbed into skin when it is incorporated into a cream as compared with kojic acid
	Kojic Acid Dipalmitate	Kojic Acid
Compatibility	Compatible with almost all cosmetic ingredients, especially advantageous for use in combination with sunscreens	may not be compatible with some organic sunscreens and preservatives due to potential hydrogen bonding,
Stability
Light	Stable	Unstable to light
Heat	Stable. A cream containing 1% KAD found no color change when kept at 45°C for 4 weeks	Especially unstable above 40°C. A cream containing 1% Kojic acid become deep yellowish brown when kept at 45°C for 4 weeks
pH	Stable between 3 and 10	Unstable when pH exceed 7
Oxidation	Not oxidizable	Particularly oxidizable
Metal ions	Not complex with metals	Chelate with metal ions ( e.g. iron) and color changes occur.
Color stability	No color change occur	Easily become yellow or brown.
