It is a bisphosphonate that can chelate iron, copper, zinc, and other ions, and is tolerant to acidic or basic oxidation.
Sequestering agents primarily function to inactivate or "sequester" the metal ions present in water. This helps prevent the formation of mineral deposits and improves the stability and effectiveness of the products. By preventing the interaction of metal ions with the formulation ingredients, sequestering agents contribute to maintain the quality and efficacy of the product.
