Description

Dipotassium 2,2'-[Ethylenebis(Oxy)]Bisacetate CAS NO 41999-73-9 is a high-purity, water-soluble potassium salt of a chelating ether diacid. This compound is valued for its ability to effectively sequester metal ions, particularly calcium and magnesium, making it a critical component in formulations requiring superior chelation and buffering capacity. It is primarily sought by manufacturers in the detergent, personal care, and industrial cleaning sectors for its stability and performance in aqueous systems.

Application

• Detergent & Cleaning Formulations: Acts as a powerful builder and chelating agent to inactivate water hardness ions, enhancing surfactant efficiency and preventing scale.
• Personal Care Products: Used in shampoos, liquid soaps, and skin cleansers as a stabilizer and sequestrant to improve clarity and shelf-life.
• Industrial & Institutional (I&I) Cleaners: A key ingredient in hard surface cleaners, degreasers, and dairy/brewery cleaners for superior mineral control.
• Textile Processing: Serves as a chelant in scouring, bleaching, and dyeing baths to prevent metal-ion catalyzed degradation of fabrics.
• Water Treatment: Employed in formulations for boiler and cooling water treatment to control scale and corrosion.
• Chemical Synthesis: Functions as a specialty intermediate or catalyst in organic synthesis and polymer production.

Quality Control

Our Dipotassium 2,2'-[Ethylenebis(Oxy)]Bisacetate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity and performance. Certificates of Analysis (COA) documenting key parameters such as assay, identity, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
