Kojic Acid

Product Paramete

Application

LGB® KAD overcomes the defects which kojic acid usually has, such as the unstability to light and heat, and the color variation caused by formation of complexes with metallic ions. LGB® KAD can preserve or promote the restraining power of kojic acid against tyrosinase activity TRP-1 activity, as well as delaying the melanogenesis.Characteristics:

1) Skin Lightening

LGB® KAD offers more efficacious skin lightening effects. Compared with kojic acid, LGB® KAD markedly enhances the inhibiting effects on tyrosinase activity, which prohibits the formation of melanin.

2) Light and Heat Stability

LGB® KAD is light and heat stable, while kojic acid tends to oxidize over time.

3) Color Stability

Unlike kojic acid, LGB® KAD does not turn brown or yellow over time for two reasons. First, kojic acid is not stable to light and heat, and tends to oxidize, which results in color change (often yellow or brown). Second, kojic acid tends to chelate with metal ions (e.g. iron), which often results in color change. On the contrary, LGB® KAD is stable to pH, light, heat and oxidation, and does not complex with metal ions, which lead to color stability.

Application:

Skin care, sun care, skin whitening/lightening, treatment for pigmentary disorders such as age spots etc.

It dissolves in hot alcohols, white oils and esters.
