Cosmetic Raw Material skin whitening Kojic acid dipalmitate CAS 79725 98 7

Product Overview

Description

Kojic acid dipalmitate powder is an improved kojic acid derivative that overcomes the kojic acid's instability of light, heat and metal ions while maintaining the inhibition of tyrosinase activity of kojic acid and the blocking of melanin formation in the skin The effect, and this inhibition is more intense than kojic acid, making it a new generation of highly effective whitening active agent. As a fat-soluble whitening active agent, kojic dipalmitate powder can be more effectively absorbed by the skin and at the same time brings good moisturization to the skin in addition to being easier to formulate.

1.Kojic Acid Dipalmitate powder offers more efficacious skin lightening effects. Compared with kojic acid, kojic acid dipalmitate markedly enhances the inhibitory effects on tyrosinase activity, which prohibits the formation of melanin.

2.Kojic Acid Dipalmitate powder is light and heat stable, while kojic acid tends to oxidize over time. 3.Kojic Acid Dipalmitate is stable within a wide pH range of 4-9, which procides flexibility to formulators.

4.Kojic Acid Dipalmitate powder 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 irons, which often results in color change. On the contrary, kojic acid dipalmitate is stable to pH, light, heat and oxidation, and does not complex with metal ions, which lead to color stability.
