How Much Do You Know About Lactic Acid?
Lactic acid (2-Hydroxypropionic Acid) is a naturally occurring α-hydroxycarboxylic acid that participates extensively in metabolic processes within organisms. It has a mild sour taste, is readily soluble in water, and is primarily produced from glucose under anaerobic conditions via lactate dehydrogenase catalysis. It is commonly found in muscles after strenuous exercise, during fermentation, and in the metabolism of various tissues. In the body, lactic acid is a key intermediate in energy metabolism and can also be converted into glucose for reuse by the liver.
Due to its safety, stability, and high biocompatibility, lactic acid has become an important raw material in many industries. As an acidulant, preservative, and pH adjuster, it is widely used in beverage, baking, meat product, and beer production. Because of its metabolizability in the human body, L-lactic acid has become an internationally recognized food and pharmaceutical additive. Furthermore, lactic acid is often used in cosmetics for gentle exfoliation and in the chemical industry for leather softening and textile processing. As a natural fermentation product, lactic acid can also be used as a feed additive, demonstrating its green and multifunctional application value.
Skincare Benefits of Lactic Acid
Lactic acid is not only a fermentation component in yogurt, but as a natural alpha-hydroxy acid (AHA), it also boasts remarkable skincare benefits:
Moisturizing: Lactic acid effectively enhances the stratum corneum's ability to retain moisture, softens the skin, improves dryness and roughness, leaving skin soft and supple.
Promoting Metabolism: Lactic acid gently promotes the renewal of dead skin cells and accelerates epidermal cell metabolism, thereby helping to fade pigmentation, improve uneven skin tone and dullness, and achieve radiant skin.
Anti-Acne: The properties of lactic acid help unclog pores and promote the smooth excretion of sebum, making it an effective ingredient for preventing and improving acne and pimples.
Anti-Aging and Anti-Wrinkle: Lactic acid can deeply stimulate fibroblasts in the dermis, promoting the synthesis of collagen and elastin, thereby enhancing skin elasticity, diminishing fine lines and wrinkles, and delaying skin aging.
Balancing the Skin Environment: Its gentle acidity helps maintain a healthy, slightly acidic environment on the skin's surface, regulates the microecological balance, and has certain antibacterial properties, which can help maintain the stability of the skin barrier.
Lactic acid has a wide range of benefits, suitable for those seeking moisturizing, brightening, anti-acne, and anti-aging effects. It is beneficial for dry, oily, and combination skin.
Multiple Applications of Lactic Acid
Lactic acid is naturally derived, safe, and highly biocompatible, making it a core raw material used in the food, daily chemical, and pharmaceutical industries.
Food Industry: As a safe natural acidulant and preservative, lactic acid is widely used in beverages, baked goods, candies, pickled products, and meat products. It can regulate pH levels, impart a mild, tangy flavor to food, and effectively inhibit harmful microorganisms, significantly extending shelf life. It also plays a key role in improving the quality of beer brewing.
Cosmetic Additives: Lactic acid's moisturizing, exfoliating, and renewal-promoting properties make it an important ingredient in many high-end skincare products (such as toners, serums, masks, and body lotions) and cleansing products. It is also commonly used in shampoos to regulate the scalp's health environment.
Pharmaceuticals: In the pharmaceutical field, lactic acid and its salts (such as sodium lactate and calcium lactate) are important components in the formulation of intravenous infusions for correcting acidosis and electrolyte supplements. Its polymer, polylactic acid (PLA), is used in the manufacture of surgical sutures, drug delivery systems, and orthopedic implants due to its biodegradability and biocompatibility.
Chemicals: Polylactic acid (PLA), produced by the polymerization of lactic acid, is a high-performance biodegradable plastic widely used in environmentally friendly packaging, textile fibers, and disposable products.
Other Applications: Lactic acid is used as an acidifying agent and preservative in the feed industry; for deliming and softening in the leather industry; and as a dyeing and finishing auxiliary in the textile industry...
