Kojic Acid Powder

Kojic Acid Powder – Premium Skin-Lightening Ingredient with 99% Purity for Cosmetic Formulations

Xi'an Le-Nutra Ingredients Inc. provides Pharmaceutical Grade Kojic Acid Powder 99% purity made in our licensed 60,000 ㎡ GMP-compliant factory. We are able to produce up to 3,000 tonnes a year. With over 14 years of fermentation technology experience, we can provide cosmetic makers worldwide with consistency of quality and stability. We are committed to quality control and our product is evaluated by HPLC assay, heavy metal analysis and microbial limit testing to meet international standards. This white crystalline component is a strong tyrosinase activity inhibitor, and is an important raw material for skin whitening cream, serum, personal care formula.

What Is Kojic Acid Powder and How Does It Work?

This product is a crystalline material of great purity, produced by controlled fungal fermentation of Aspergillus oryzae. 5-hydroxy-2-(hydroxymethyl)-4-pyrone (CAS NO.: 501-30-4) is a chemically defined compound and a potent tyrosinase inhibitor for dermatological uses.

The mechanism involves the chelation of copper ions in the tyrosinase enzyme complex. The product complexed these critical metal ions and so interfered with melanogenesis pathway at the enzymatic level. This stops the conversion of L-tyrosine to melanin precursors and effectively reduces the production of pigmentation.

This ingredient is a proven non-hydroquinone solution for formulators looking to address hyperpigmentation concerns. Molecular weight is 142.11 g/mol and it can penetrate well into the epidermal layer where melanocytes are active.

Technical Specifications and Quality Standards

We enforce strict quality requirements throughout the manufacturing process to guarantee consistent formulations and regulatory compliance. Every batch is fully tested before being released.

The substance has great solubility in water (around 44g/L at 25°C), ethanol and ethyl acetate. Melting point is in the region of 152-156°C which provides thermal stability during the normal production process.

Core Functional Advantages for Cosmetic Applications

Your formulas have a variety of therapeutic capabilities for a wide range of skincare conditions. This component has proven performance across a broad spectrum of application sectors.

Tyrosinase Inhibition: Clinical investigations show efficient inhibition of melanin formation through chelation of copper ions which are crucial to enzymatic function. This makes it a better treatment for melasma, age spots and post-inflammatory hyperpigmentation.

Antioxidant Protection: The hydroxyl groups in the molecular framework neutralise free radicals and help reduce oxidative stress, which promotes skin ageing. This double function makes the product more valuable.

Antibacterial Activity: Natural antibacterial activity to control acne producing germs and to maintain the integrity of the formulation. You can reduce the need for extra preservatives for certain formulas.

Pigmentation Correction: With repeated usage at concentrations of 1-4%, skin tone uniformity is shown to significantly improve as confirmed by dermatological testing methods within 8-12 weeks.

Application Scenarios in Personal Care Formulations

Kojic Acid Powder is used by professional formulators in a variety of product categories to suit unique customer needs. Knowing how to use it makes you get the most out of it.

Whitening & Brightening Products: Use in face creams, serums and emulsions at 1-3% level for visible lightening results. This substance has synergy with derivatives of vitamin C and niacinamide.

Spot and Pigmentation Treatments: For targeted hyperpigmentation, treatments need 2-4% concentration. Combine with penetration enhancers for enhanced dermal delivery.

Anti-aging formulations: Its antioxidant benefits work with retinoids and peptides in complete anti-aging systems. 1-2% to give oxidative protection without affecting key active ingredients.

Applications in Body Care: Soaps, body lotions and hand creams can have 0.5-2% to improve general skin tone. It is stable in soap bases (if the pH is maintained).

Quality Control and Manufacturing Excellence

Our production facility is equipped with a full complement of tests to assure pharmaceutical-grade quality. The production batch is controlled in several steps.

HPLC assay testing demonstrates purity levels are routinely >99% ICP-MS analysis guarantees heavy metals including lead, arsenic and mercury are far below the 10ppm level. Colour stability tests subject samples to UV radiation and heat to test resistance to oxidation.

Microbial limit testing is used to confirm the absence of harmful organisms such Staphylococcus aureus and Pseudomonas aeruginosa. Particle size distribution analysis is required for uniform dissolving characteristics which are important for large scale manufacturing.

Our 6 multipurpose production lines include GMP, ISO and FDA standards. With 30+ days of safety stock and 98% on time delivery rate, we offer your production schedules supply chain stability.

FAQ

Q: How do I use this ingredient in oil based formulations?

A: The usual version is water soluble, but we also have the Kojic Acid Dipalmitate (oil soluble derivative) for inclusion in the oil phase. Add to oil phase at 80-90°C until fully dissolved, then emulsify.

Q: Is this product irritating to the skin?

A: The substance is well tolerated in recommended dosages (1-4%). But for sensitive skin, lower amounts or pairing with relaxing ingredients like allantoin or bisabolol may be a better option.

Q: How long will it last, if kept in the appropriate manner?

A: The material has a guarantyd shelf life of at least 24 months when stored in sealed containers under cold, dry and dark circumstances. There was little loss in the stability testing of these settings.

Q: Can you use this substance with vitamin C? A. Yes.

A: Yes, it has a synergistic brightening effect when used in conjunction with L-ascorbic acid or stable derivatives such as ascorbyl glucoside. Maximum stability of both compounds is maintained at pH 3.5-4.5.

Q: How does your product differ from standard grades?

A: Our stuff is pharmaceutical grade meaning it's more refined and has more quality controls. This has led to increased colour stability, lower impurity profiles and improved batch-to-batch uniformity.
