Teccnodieci Sodium Tripolyphosphate (STPP); It is an electrode widely used in the ceramic sector. It is used at a rate of 0.3% to 0.6%, depending on the formulation, to reduce the viscosity of the glaze composition. STPP also provides low viscosity in wet grinding, thus increasing the agitation in the mill, which shortens the grinding time and saves money and time. It also provides a homogeneous distribution in the application of the glaze on the tile. It is sold in granular and powder form. Sodium Tripolyphosphate (stpp), which dissolves easily when in contact with water, can be added by opening it with water later. Sodium tripolyphosphate is also widely used in the soap and detergent industry.
As packaging; It is sold in 25 kg bags and 1000 kg Bigbags.
Since our country is not rich in phosphate, it is imported from many countries including China, Tunisia, Italy. STPP is widely used in the detergent and soap sector as well as the ceramic sector.

Areas of use
It is used in various applications as a preservative for seafood, meat, chicken and pet food. It is also used as a builder in soaps and detergents to increase cleaning power, as well as in toothpastes. The Food and Drug Administration considers STPP, along with salt, vinegar, and baking soda, to be “generally accepted as safe.”
STPP is used as a builder in most household cleaning products, as well as in human food, animal feed, industrial cleaning processes, and ceramic manufacturing. STPP is widely used in regular and concentrated laundry detergents and automatic dishwasher detergents (in powder, liquid, gel, and/or tablet form), toilet cleaners, surface cleaners, and coffee machine cleaners. It also provides chemical functions such as breaking down “water hardness,” ensuring the effectiveness of surfactants, buffering pH, emulsifying dirt and preventing scale, hydrolyzing oil, and dispersing dirt particles.
It is used in toothpaste, soap, and detergents to improve cleaning capabilities. It is also a structuring filler in soaps and detergents. STTP has the ability to remove water hardness and bind dirt to its own structure by separating it from laundry.
STPP is widely used in powder, liquid, gel, tablet laundry detergents, dishwasher detergents, toilet and surface cleaners. Its function here is to separate water hardness, which allows surfactants to work effectively, pH buffering, dirt emulsification and prevention of sedimentation, hydrolysis of oil and dissolving and dispersing dirt particles.
STPP is also used in industrial cleaners.
STPP is also used in water softening and as a preservative in food.
