DESCRIPTION

Kojic Acid

Kojic acid is a naturally derived organic compound obtained mainly from fungal species such as Aspergillus oryzae. It comes as a white to slightly beige crystalline powder, soluble in water and alcohol. It is widely used in cosmetics for its brightening, antioxidant and preservative properties.

Practical formulation guide
Usage level: Recommended usage level: • Face creams, serums and lotions: 0.5–2 % • Soaps and cleansers: up to 2 % (quick rinse, lower risk of irritation) • Masks and targeted treatments: 1–4 % (controlled, non-daily use)
How to use and incorporate: Dissolve in the water phase (salicylic acid requires a solvent such as butylene glycol, propylene glycol, alcohol or warm glycerin) and adjust the final pH with a base (triethanolamine, sodium hydroxide or arginine), measuring with a pH meter.
Formulation tips:
  • Final pH determines the performance and tolerance of the product; always measure with a calibrated pH meter.
  • In leave-on products with alpha-hydroxy acids, include a sunscreen use recommendation on the label.
  • Before scaling up, make a pilot batch and run a stability test (cycles at 4 / 25 / 45 °C/39 / 77 / 113 °F for 4 weeks, checking odor, color, pH, viscosity and separation) in the final packaging.
Compatibility: Incompatibilities
  • Unstable in very acidic or very alkaline media. • Oxidizes in the presence of light, heat and oxygen. • Not compatible with metal ions (Fe, Cu, Mn), so chelating agents (e.g., EDTA) are recommended for stabilization.
Storage: Shelf life: 24 months under proper conditions. • Keep in its original container, tightly closed, to prevent moisture absorption. • Store in a dry, cool, ventilated place, protected from direct sunlight. • Keep in areas free of excessive dust so as not to affect product purity.
Precautions: • For use only in cosmetic or industrial formulations. • Do not use directly on the skin without proper formulation. • May cause eye and skin irritation at high concentrations. Handling Use personal protective equipment (PPE): lab coat, gloves, mask and safety glasses.
Technical information for formulators: This sheet describes industrial uses of the raw material in the development of cosmetic products. It is not an efficacy claim for any finished product. The person responsible for the formulation must validate the concentration, compatibility and claims of their product in accordance with applicable regulations.
