Product Description
Phosphoric Acid (85%) is a mineral acid widely used in various industrial and food-grade applications. It is a triprotic acid (H3PO4) notable for its moderate acid strength and versatility. The 85% concentration is common for both food-grade and technical uses, appearing as a colorless, odorless, viscous liquid. It plays a vital role as an acidity regulator and flavoring agent in food processing, pH adjuster in water treatment, and an essential component in detergent, fertilizer, and metal treatment manufacturing processes. Zenco Systems Ltd supplies this high-quality phosphoric acid reliably across Kenya, Uganda, Tanzania, Rwanda, and neighboring East African countries. Safe handling and storage in cool, dry, well-ventilated areas are critical to prevent decomposition and corrosion. Zenco Systems Ltd also provides technical support to ensure optimum and safe use of the chemical in various industry sectors.
