Tranexamic Acid Powder (also known as TXA or Transaminic acid in some contexts) is a high-performance cosmetic raw material, valued globally for its potent skin-brightening and anti-discoloration capabilities. Originally recognized in the medical field as an anti-fibrinolytic agent to manage bleeding, its exceptional dermatological properties—particularly its ability to effectively target hyperpigmentation—have propelled it to the forefront of advanced skincare formulation. As a white, crystalline, and water-soluble powder, it's the ideal, concentrated form for seamless integration into high-quality cosmetic products.
The key to this product's effectiveness lies in the active ingredient itself:
While many suppliers offer TXA Powder, our partnership provides a distinct, product-specific edge, leveraging our core OEM/ODM expertise, Guaranteed Raw Material Purity & Stability. As an OEM partner, we don't merely sell the powder; we specialize in formulating with it. For brands looking to launch globally, our OEM service provides streamlined support in navigating the complex regulatory landscape surrounding Tranexamic Acid concentrations and claims across different markets, mitigating your risk and accelerating your time to market—a service essential for success in this highly competitive ingredient category.
Our TXA is refined to a purity level exceeding 99.8%, this ultra-high purity minimizes the risk of impurities causing irritation or destabilizing your final formulation, ensuring your product results your end-consumers expect.
We go beyond chemical purity to master physical structure. Our proprietary micronization process creates a controlled, uniform particle size distribution (D50 < 20μm). This is critical for:
Stability Assurance: A common failure point is ingredient degradation. Our technical team provides dedicated support to help you build a stabilizing matrix around our TXA, protecting its efficacy in your specific base formula and extending your product's shelf life.

Yes, it is generally safe and well-tolerated for topical use. It has low irritation potential compared to ingredients like hydroquinone or kojic acid. Patch testing is still recommended for sensitive skin.
Yes, it can be safely combined with both. Vitamin C enhances antioxidant protection, while Niacinamide supports skin barrier repair and brightening effects.
They work differently. Tranexamic Acid inhibits melanocyte activation, while Alpha Arbutin reduces melanin production. Combining them often provides synergistic whitening results.
Yes, but they should not be applied in the same step. Use exfoliating acids first, then apply Tranexamic Acid serum to minimize irritation and maximize absorption.
It is a synthetic amino acid derivative (from lysine), but it is considered safe and effective for cosmetic and medical applications.
For topical cosmetic applications such as lotions, serums, creams, and masks, the typical recommended concentration range is between 0.5% and 3%.
