KOJIC ACID DIPALMITATE
Kojic acid dipalmitate is produced by chemical synthetic method. It 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. Kojic acid dipalmitate can preserve or promote the restraining power of kojic acid against tyrosinase activity TRP-1 activity, as well as delaying the melanogenesis.
CHARACTERISTICS
1. It is not easy for color variation. It ameliorates the stability of kojic acid in color.
2.It restrains the activity of tyrosinase TRP-1, so the prevention or postponement of the melanogenesis is possible.
3.The product is stable under the condition of pH 3-10.
