Tranexamic Acid Technical FAQ
How does Onerchem ensure the stability of Tranexamic Acid in water-based formulas?
Our Tranexamic Acid is ultra-pure (≥99.5%), which minimizes the metallic impurities that often cause discoloration. It is inherently stable to light and heat. We recommend maintaining a pH between 3.0 and 8.0 to ensure long-term clarity and efficacy in your final product.
Can it be used alongside high-concentration Vitamin C?
Yes. In fact, they are synergistic. While Vitamin C acts as a direct antioxidant, Tranexamic Acid addresses the inflammatory pathways of pigmentation. Combining them provides a dual-action approach that is highly effective for post-sun repair products.
Is your Tranexamic Acid compliant with global cosmetic regulations?
Absolutely. Our material meets the purity standards of USP and BP. It is globally approved for use in cosmetics in the EU, USA, China, and Japan, with recommended usage levels typically between 0.5% and 3.0%.
