Tranexamic Acid-Cosmetic Grade（CAS 1197-18-8）
Tranexamic acid is a classic safe whitening and anti-pigmentation cosmetic active ingredient, widely used in global medical beauty and daily skincare industry. Different from common whitening ingredients such as arbutin and niacinamide which only inhibit tyrosinase, tranexamic acid blocks melanin transmission pathway from the middle link of melanin metabolism. It can effectively improve stubborn chloasma, inflammatory acne marks and sun-induced dark spots, solve skin dullness caused by inflammation. With excellent water solubility, ultra-low irritation and strong acid-base stability, it is compatible with most mainstream whitening actives to form synergistic brightening formula, becoming an essential raw material for medical beauty whitening skincare products.
Key Benefits
• Unique melanin blocking mechanism: inhibit melanin transmission instead of single tyrosinase inhibition
• Targeted improvement of stubborn chloasma with remarkable effect that common whitening ingredients cannot match
• Effectively fade inflammatory pigmentation, red acne marks and post-treatment skin darkening
• Strong stability, resistant to high temperature, acid and alkali, no discoloration during production and long-term storage
• Ultra-mild formula, non-irritating to sensitive skin, no skin barrier damage
• Excellent water solubility, rapid dissolution in water phase without heating and co-solvent assistance
• Perfect synergistic effect with alpha arbutin, beta arbutin, niacinamide and VC derivatives
• Reduce skin inflammatory reaction, assist skin barrier repair after sun exposure and medical beauty operation
• Non-photosensitive component, finished products can be used day and night without light avoidance
• High cost performance, suitable for both high-end medical beauty line and mass daily skincare line
Applications
• Medical beauty brightening essence: Recommended dosage 2%-5%
• Anti-chloasma spot cream: Recommended dosage 1.5%-3%
• Soothing and brightening toner: Recommended dosage 1%-2%
• Repair mask for inflammatory acne marks: Recommended dosage 1%-3%
• After-sun repair skincare products to prevent ultraviolet pigmentation
• Post-operative repair skincare for medical beauty microneedle and laser treatment
• Compound whitening skincare formula, matched with multiple brightening raw materials
• Daily sunscreen products to reduce tanning and pigmentation caused by UV rays
• Sensitive skin soothing brightening skincare series

Frequently Asked Questions (FAQ) & Document Request Frequently Asked Questions (FAQ) & Document Request
Q1: What is the difference between tranexamic acid and common whitening ingredients like niacinamide and arbutin?
A: Niacinamide and arbutin mainly inhibit tyrosinase to reduce melanin production, while tranexamic acid blocks melanin transferring to keratinocytes. It targets inflammatory pigmentation and chloasma which cannot be improved by conventional whitening ingredients, making it irreplaceable for medical beauty skincare formulas.
Q2: Does tranexamic acid affect formula pH value? How to match the formula system reasonably?
A: Tranexamic acid aqueous solution is weakly alkaline, which will slightly increase the pH of water-based formula. We suggest adjusting the final formula pH to 5.5-7.5 to keep the whole system stable, and avoid long-term compounding with strong acidic raw materials.
Q3: What is the optimal feeding temperature during cosmetic production?
A: Tranexamic acid owns excellent high temperature resistance, it can be added directly at 80℃-85℃ high temperature water phase without activity loss. For better formula stability, adding at 40-60℃ cooling stage is also available.
Q4: Will tranexamic acid cause formula yellowing or precipitation in long-term storage?
A: Our high-purity cosmetic grade tranexamic acid has extremely low impurity content, no precipitation, no yellowing and no discoloration after 24 months of sealed storage, which keeps finished products transparent and stable all the time.
Q5: Can you provide complete compliance documents for cosmetic filing and export customs clearance?
A: We can provide stamped COA, MSDS, raw material safety assessment report, SCCS compliance certificate and third-party test reports, supporting cosmetic registration in China, EU, USA, Southeast Asia and other regions smoothly.
Q6: What is the recommended compound ratio when matching tranexamic acid with alpha arbutin?
A: The classic compound ratio is 2% tranexamic acid + 2% alpha arbutin, which realizes dual-path melanin inhibition, significantly improving overall brightening effect and reducing pigment rebound probability.
