CHEMICAL NAME:
2-Palmitoyloxymethyl-5-palmitoyloxy-gamma-pyrone
Empirical Formula: C38H66O6
Kojic acid dipalmitate 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 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.
SPECIFICATION
Appearance: white to light yellow powdery crystals.
Melting point: 92-97 Celsius degree
Assay: not less than 99%
