Industrial Uses

1.Personal Care
  • pH adjuster: It can be used to bring the pH down in products that are too alkaline or to fine-tune the pH in formulations to match the skin’s natural pH, which is typically around 4.5–5.5. Lactic acid helps to ensure that these ingredients remain at their optimal pH levels, preventing degradation or ineffectiveness.
  • Exfoliants: Lactic acid is an AHA that works by loosening the bonds between dead skin cells (keratinocytes) on the outermost layer of the skin, called the stratum corneum. By breaking these bonds, lactic acid encourages the shedding of dead cells, which promotes the growth of fresh, new skin cells.
2. Food & Healthcare Ingredients
  • Food Preservative: Lactic acid is widely used as a preservative in food products due to its ability to lower pH and inhibit the growth of spoilage microorganisms. It is found in products like pickles, fermented foods, and dairy products.
  • Acidity Regulator: Lactic acid is used to control the acidity (pH) of various food products, including sauces, soft drinks, and baked goods. It can enhance the taste and improve the shelf life of certain foods.
  • Flavoring Agent: Lactic acid contributes a tangy or sour flavor to food products. It is often used in confectionery, beverages, and dairy-based products like yogurt and cheese.
3. Pharmaceuticals
  • Drug Formulation: Lactic acid is used in pharmaceutical formulations, particularly in the production of certain injectable medications and oral products. It can help in creating controlled-release drug delivery systems.
  • Buffering Agent: Lactic acid is used as a buffering agent in pharmaceuticals to help maintain the pH stability of medications.
4. Fabric Solutions
  • Drug Formulation: Lactic acid is used in pharmaceutical formulations, particularly in the production of certain injectable medications and oral products. It can help in creating controlled-release drug delivery systems.
  • Buffering Agent: Lactic acid is used as a buffering agent in pharmaceuticals to help maintain the pH stability of medications.
5. Chemical Synthesis
  • Solvent and Intermediate: Lactic acid serves as an intermediate in the synthesis of various chemicals, including lactates, which are used in a wide range of applications such as solvents, emulsifiers, and surfactants.
