Industrial Uses

1. Personal Care

  • pH Adjuster in Skincare Products: Phosphoric acid is used as a pH adjuster in cosmetics and personal care products, such as shampoos, creams, and lotions, ensuring that products remain stable and safe for use.
  • Exfoliant: In some skincare formulations, it is used as a mild exfoliant due to its ability to remove dead skin cells and improve skin texture.

2. Food & Healthcare Ingredients

  • Acidulant: Phosphoric acid is used in food and beverages, particularly in soft drinks, to provide a tangy or sour taste and to adjust the pH levels, enhancing flavor and preservation.
  • Preservative: It helps extend the shelf life of food products by lowering pH, inhibiting the growth of microorganisms and contributing to food safety.
  • Antioxidant: In certain food and healthcare formulations, phosphoric acid helps to stabilize ingredients by preventing oxidative degradation.

3. Animal Healthcare

  • Nutrient Additive in Animal Feeds: Phosphoric acid is used as a phosphorus supplement in animal feed formulations, providing essential nutrients that support bone health and overall animal growth.

4. Construction

  • Cement Additive: Phosphoric acid is used in the construction industry as a setting agent and accelerator in cement-based products, improving workability and setting times, particularly in high-strength or specialized applications like concrete additives.

5. Agrochemicals

  • Acidifiers & pH Modifiers: Used to lower the pH of agrochemical solutions (like fertilizers and pesticides), enhancing stability and nutrient uptake by plants. Also helps prevent precipitation of essential nutrients in liquid formulations.
  • Soil Conditioner: It is used to adjust the pH of soils, making certain nutrients more available to plants, especially in soils with high alkalinity.

6. Water Treatment

  • pH Control in Water Treatment: In water treatment facilities, phosphoric acid is used to adjust the pH of water, ensuring that it meets the necessary safety and quality standards. It also helps prevent corrosion in water systems by forming a protective phosphate layer on metal surfaces.
