What is Kojic Acid Powder?

Kojic Acid is a naturally occurring organic acid produced through the fermentation of certain fungi, particularly Aspergillus oryzae. It is chemically identified as C6H6O4 with CAS number 501-30-4, and typically appears as a white crystalline powder. Kojic Acid is best known for its function as a melanin synthesis inhibitor, making it widely used in topical skin-lightening and brightening formulations.

As a trusted Kojic Acid manufacturer and supplier, we offer a high-purity grade of 99%, produced under cosmetic-grade GMP conditions. The ingredient is popular in the formulation of creams, serums, masks, and soaps aimed at reducing the appearance of dark spots, age spots, and uneven skin tone.
