Analysis
Samples: Standard solution and Sample solution
Calculate the percentage of each individual impurity in the portion of Tranexamic Acid taken:
Result = (rU/rS) × (CS/CU) × (0.1F)
rU = peak response for each impurity from the Sample solution
rS = peak response for tranexamic acid from the Standard solution
CS = concentration of USP Tranexamic Acid RS in the Standard solution (µg/mL)
CU = concentration of Tranexamic Acid in the Sample solution (mg/mL)
F = relative response factor (see Impurity Table 1)
Acceptance criteria
Individual impurities: See Impurity Table 1.
Total impurities: NMT 0.2%
[Note-Disregard any peak less than 0.025%.]

Tranexamic Acid (CAS: 1197-18-8) is a synthetic derivative of the amino acid lysine.Tranexamic acid (commonly marketed in tablet form as Lysteda and in IV form as Cyklokapron in the U.S. and as Transamin,Transcam in Asia, and Espercil in South America) is often prescribed for excessive bleeding. Tranexamic acid is an antifibrinolytic that competitively inhibits the activation of plasminogen to plasmin, a molecule responsible for the degradation of fibrin. Fibrin is the basic framework for the formation of a blood clot in hemostasis.Tranexamic acid has roughly 8 times the antifibrinolytic activity of an older analogue, ε-aminocaproic acid. It was first patented in 1957 and received its initial US approval in 1986. Tranexamic Acid Applicaiton Used as whitening cosmetics It is widely used clinically in the fields of surgery, internal medicine, urology, obstetrics and gynecology, etc. to treat various bleeding diseases and abnormal bleeding during surgery, etc. It is considered as a hemostatic medicine, which is mainly used for hemostasis after major surgery and postpartum. Of course, hemostasis is probably the minimum reason why many toothpastes are added to hope to have an effect.
Tranexamic Acid (CAS: 1197-18-8)
Heart surgery
Commonly used in cardiac surgery, both with and without cardiopulmonary bypass. It replaces aprotinin.
Menstrual bleeding
Used as firstline nonhormonal treatment of dysfunctional uterine bleeding, and heavy bleeding associated with uterine fibroids. A recent study showed patients treated with tranexamic acid are more likely to develop thrombosis and necrosis in their fibroids, and may result in pain and fever.
Whitening effect
Clinical studies for years have proved that tranexamic acid can dilute spot effectively and rapidly, which helps to demonstrate a perfect white and bright skin. The spot-removing effect of tranexamic acid is about 50 times over Vitamin C, and 10 times over AHA. The concentration limit of usage is 2%-3%, and in cosmetics the amount is around 0.5%
1. Good stability
Compared with traditional whitening ingredients, tranexamic acid has high stability, acid and alkali resistance, and is not easily affected by temperature environment; No carrier protection, no transmission system damage, no stimulation.
2. The skin system is easy to absorb
It is especially suitable for lightening spots, whitening and balancing the overall skin tone. In addition to lightening the spots, tranexamic acid can also improve the transparency of overall skin color and the dullness of local skin mass.
3. It can fade black spots, yellow freckles, acne marks, etc
Black spots are caused by UV damage and skin aging and other factors. Clotting acid can inhibit the activity of tyrosinase and melanocytes, reduce the production of melanin from the basal layer of epidermis, and also has the effect of removing red spots.
4. High safety
The highest concentration in cosmetics is 2%~3%.
5. Whitening effect
Tranexamic Acid is suitable to all kinds of skin for removing pigmentation, whitening skin and reducing spots, such as: Pigmentation after sun exposure; Dark spots; Sensitive skin; Acne and inflammation; Postoperative care after laser, pulsed light treatment.
