Property |
Kojic Acid Dipalmitate |
Conventional Kojic Acid |
|---|---|---|
Solubility |
Oil-soluble (log P ≈ 8.7) |
Water-soluble (log P ≈ -0.64) |
Stability |
High — stable at pH 3.5–8.0; less than 5% degradation after 30 days at room temperature |
Low — prone to oxidation and photodegradation |
Skin Permeation |
Enhanced lipophilicity improves stratum corneum compatibility |
Limited penetration |
Irritation Potential |
Lower — less likely to cause sensitivity |
May cause irritation in sensitive skin |
Formulation Compatibility |
Suitable for oil-phase incorporation in emulsions, serums, soaps |
Requires water-phase addition; stability challenges |
Color Impact |
Minimal color impact |
May cause discoloration over time |
