What Kojic Acid Does in Cosmetic Formulations
01
Supports Brightening Formulas
Kojic Acid is used as a tyrosinase-inhibiting cosmetic active in formulas targeting the appearance of dark spots, dullness, and uneven-looking skin tone.
02
Established Brightening Active
Kojic Acid is a recognized cosmetic brightening ingredient with clear INCI and CAS identity, giving procurement and formulation teams a familiar active for even-tone product concepts.
03
Fits Water-Based Formats
Water solubility makes Kojic Acid relevant to serums, essences, gels, mask essences, and the water phase of properly designed emulsions.

Why Source Kojic Acid from Noyain
Defined Grade for Cosmetic Development
Our Kojic Acid is supplied with a ≥99% assay specification and controlled quality parameters including appearance, loss on drying, iron, chlorides, and heavy metals. This provides a reliable starting point for cosmetic formulation evaluation.
Documentation Ready for Supplier Review
Support your ingredient qualification process with current-batch COA, Product Specification, and SDS. Review key quality information before moving to formulation approval and commercial purchasing.
From Sample Testing to Bulk Supply
Evaluate the material in your own formula before scaling up. We support the transition from sample evaluation to commercial orders with packaging options, MOQ confirmation, and sourcing communication.
Formulation notes
How to Use Kojic Acid in Formulations
Kojic Acid formulation performance depends on proper incorporation, formula pH control, and stability management. The following considerations can help formulators evaluate dissolution, compatibility, and finished-product stability during development.
Get Free SampleIncorporation
Pre-dissolve Kojic Acid in the water phase and confirm complete dissolution before final processing. Evaluate clarity and compatibility in the complete formulation.
Formula pH
Our MSDS reports a pH of 3.5-5.0 for a 2% aqueous solution. Establish the final formula pH based on the complete formulation and stability testing.
Stability
Kojic Acid can be sensitive to heat, light, oxidation, and metal ions. Monitor color, pH, assay, precipitation, and odor during finished-product stability testing.
Use Level
Select the final use level according to product type, formulation design, safety assessment, and target-market requirements. In the EU, Kojic Acid is restricted to a maximum of 1% in ready-to-use face and hand products.

Frequently Asked Questions
Questions from Formulators and Buyers
- What is Kojic Acid?Kojic Acid is a cosmetic brightening active identified by INCI name Kojic Acid and CAS 501-30-4. Our supplied grade is a white to cream-colored crystalline material with an assay specification of ≥99%.
- Why is Kojic Acid used in brightening formulas?Kojic Acid is recognized as a tyrosinase inhibitor and is used in formulas targeting dullness, the appearance of dark spots, and uneven-looking skin tone. Finished-product results depend on the selected concentration, formulation, stability, and supporting efficacy testing.
- What is the recommended use level?Select the final level according to the product format, safety assessment, formulation design, and sales market. In the EU, Kojic Acid is limited to a maximum of 1% in ready-to-use face and hand products.
- Is Kojic Acid water soluble?Yes. Our MSDS states that Kojic Acid is soluble in water, ethanol, and acetone. For cosmetic development, pre-dissolve it in the water phase and confirm clarity and stability in the complete formulation.
- Is Kojic Acid the same as Kojic Dipalmitate?No. They are different chemical ingredients. Kojic Acid is water soluble, while Kojic Dipalmitate is a lipophilic derivative with different molecular identity, formulation behavior, and regulatory considerations.
- What stability checks are important?Monitor color, odor, pH, active assay, precipitation, viscosity, and packaging compatibility under the intended stability conditions. Kojic Acid can be affected by heat, light, oxidation, and metal ions.
- What should buyers request before a bulk order?Request a sample, current-batch COA, Product Specification, SDS/MSDS, and quotation. Confirm assay, appearance, packaging, MOQ, lead time, batch availability, and target-market document requirements before commercial approval.
