What Is The Recommended Dosage Of Sodium Tripolyphosphate In Detergents?

The recommended dosage of sodium tripolyphosphate (STPP) in detergents varies depending on the specific formulation and intended use of the detergent. However, due to the environmental concerns associated with STPP, its use in detergents has been restricted or banned in some countries.

In general, STPP is used as a builder in laundry detergents to enhance cleaning performance by sequestering hard water ions and preventing the deposition of dirt and other impurities onto fabrics during washing. The typical usage level of STPP in laundry detergents ranges from 10-30% by weight, but some formulations may use higher or lower amounts depending on the specific application and desired performance characteristics.

It should be noted that the use of STPP in detergents has been criticized for its negative impact on the environment, particularly its contribution to eutrophication in freshwater bodies. As a result, many manufacturers have developed alternative formulations that do not rely on STPP as a builder, or have reduced the amount of STPP used in their products.
