Due to the extensive use of sodium tripolyphosphate in detergents, its discharge may lead to eutrophication of water bodies. The European Union, United States and China have implemented phosphorus restriction policies, promoting phosphorus-free or low-phosphorus detergents.
As a additive (E451), STPP is used for water retention and texture improvement in meat and sea products. Some countries have imposed stricter restrictions due to increased safety concerns.
Since 2022, STPP prices have fluctuated due to global supply chain issues and rising raw material costs. China's export prices significantly impact the international market.
Research institutions are developing phosphorus-free detergents and water treatment agents (zeolite, polycarboxylate) to reduce reliance on STPP.
