What Is Kojic Acid Dipalmitate Powder?
This ingredient represents an advanced ester derivative of kojic acid, specifically engineered for cosmetic applications. Unlike traditional kojic acid, this modified form provides superior stability and oil solubility.
You get better formulation compatibility across various product types.
The molecular structure combines kojic acid with palmitic acid chains. This transformation creates a lipid-soluble compound that integrates seamlessly into emulsions, serums, and creams.
Key characteristics include:
- Oil-soluble properties for enhanced skin penetration
- Stable across pH ranges 3-10 (ideal at 4-7)
- Resistant to oxidation and heat degradation
- Compatible with other cosmetic actives
- Suitable for leave-on and rinse-off formulations
Your products maintain potency throughout their shelf life when you choose this stabilized form.
