Kojic Acid Powder (CAS 501-30-4) is a naturally derived organic acid produced through microbial fermentation, primarily by specific fungal strains. It has a long history of use in fermentation-based processes and is widely valued in cosmetic and personal care applications for its excellent water solubility and formulation compatibility.
In cosmetic formulations, kojic acid is commonly used for its interaction with tyrosinase-related activity, making it a popular functional ingredient in products designed to support a more even-looking complexion and enhanced skin radiance.
Natural Field supplies high-purity kojic acid powder bulk with strict quality control to ensure batch-to-batch consistency and reliable formulation performance. Our kojic acid powder for sale is suitable for OEM/ODM projects and global cosmetic manufacturing, supported by complete technical documentation.
