In the pharmaceutical field, high - pure grade lactic acid is used in the production of drug formulations. For example, it can be used as an excipient in tablets and capsules. Its high purity ensures that it does not introduce unwanted contaminants into the drug product, which is crucial for the safety and efficacy of medications.
Lactic acid can also be used in the preparation of biodegradable drug - delivery systems. Its chemical properties allow it to form polymers such as polylactic acid (PLA), which is a well - known biodegradable material. These polymers can encapsulate drugs and release them in a controlled manner in the body, improving the therapeutic effect.
High - pure lactic acid is a popular ingredient in skincare products. In chemical peels, for example, it is used to exfoliate the skin. The high - purity lactic acid can penetrate the outer layer of the skin more effectively and help to remove dead skin cells, improving skin texture and reducing the appearance of fine lines and wrinkles.
It is also used in moisturizers and other skincare formulations. Lactic acid can help to adjust the pH of the skin's surface, making it more acidic, which is beneficial for maintaining a healthy skin barrier. The high - purity grade ensures that there are no harmful substances that could potentially irritate the skin.
