Kojic Acid (INCI: Kojic Acid), a pyran derivative, has good whitening and spot-lightening functions. It is made from glucose as a raw material through a series of steps such as Aspergillus and Candida fermentation, filtration, and concentration. Its whitening mechanism is inhibition Tyrosinase activity, while inhibiting the activity of N-hydroxyindole acid (DHICA) oxidase, blocking the polymerization of dihydroxyindole (DHI), is a rare single whitening agent that can inhibit multiple enzymes at the same time .
However, kojic acid has the instability of light, heat and metal ions. It is easily oxidized in the air and is not easily absorbed by the skin. Therefore, kojic acid related derivatives came into being. Not only the whitening mechanism is the same as that of kojic acid, but also the effect is stronger acid.
What is kojic acid dipalmitate
Kojic acid dipalmitate is a fat-soluble derivative of kojic acid, which is more easily absorbed by the skin. It has a stronger ability to inhibit melanin production than kojic acid, effectively inhibits tyrosinase activity, and can protect against sun and brighten skin tone. Has a better whitening effect. At the same time, it has an excellent repairing effect on chloasma, age spots, pigmentation and other skin problems. In addition, kojic acid dipalmitate not only overcomes the shortcomings of kojic acid's instability to light and heat and discoloration when exposed to metal ions, but also does not affect the efficacy of additives in the Cosmetic system, such as sunscreens, active ingredients, preservatives, etc. , Has a very good compounding performance.
What are the effects of kojic acid dipalmitate:
◆ Whitening: Prevent tyrosinase activation, prevent pigmentation, and strongly inhibit melanin synthesis;
◆ Freckles: Improve skin pigmentation, can fight age spots, chloasma, freckles and general pigmentation.
◆ Sun protection: It has the function of absorbing ultraviolet rays.
Application of kojic acid dipalmitate:
Kojic acid dipalmitate is mainly used as a whitening agent, freckle removing agent, skin conditioner and emollient in skin care products. As a fat-soluble whitening agent, it has good compatibility with other raw materials. Therefore, it is widely used in whitening skin care products. Its product forms are mostly toners, essences, lotions, creams, facial masks, etc.
