Trisodium Phosphate (Technical Grade)

Trisodium Phosphate for Heavy-Duty Cleaning and Industry

Trisodium Phosphate, commonly called TSP, is a white, water-soluble salt that forms a strongly alkaline solution. Trisodium phosphate cuts grease, softens water and prevents scale. As a result, it is a classic ingredient in heavy-duty cleaners and boiler water treatment.

We stock technical grade Trisodium Phosphate made in China, supplied in 25 kg bags. Wisdo Merchants Chemical Division delivers it across Kenya and East Africa from Industrial Area, Nairobi.

Applications of Trisodium Phosphate

Heavy-Duty Cleaning

Cleaning contractors and formulators use TSP for floors, walls, kitchens, engines and workshop surfaces. Painters also use it to clean and degloss surfaces before repainting. Browse our cleaning and disinfection chemicals.

Boiler and Water Treatment

Boiler operators dose phosphate to control scale and corrosion. Always follow a water treatment specialist’s programme.

Metal Treatment and Detergents

Metal finishers use TSP in alkaline degreasing baths before plating or phosphating. Detergent makers use it in some industrial formulations, alongside builders such as our STPP detergent builder. See our metal treatment chemicals.

Safety and Handling

• Eye damage: Its strong alkalinity can cause serious eye damage. Wear goggles.
• Skin irritation: Wear gloves, especially with concentrated solutions.
• Dust: Avoid breathing the dust.
• Surfaces: It can dull paint, aluminium and glass. Rinse thoroughly after cleaning.
• Environment: Phosphates feed algae. Follow local discharge rules.

Always read the Safety Data Sheet before use.

Storage and Shelf Life

Store bags in a dry, covered place, sealed and away from acids. The powder absorbs moisture and can cake.
