Primary Application Directions of Sodium edetate / EDTA-4NA powder CAS 64-02-8:
Its use is primarily driven by the need for alkaline chelation or formulation compatibility.
Industrial & Institutional Cleaning: Dominant use in heavy-duty alkaline cleaners, degreasers, and detergents (e.g., metal cleaners, oven cleaners, industrial floor cleaners). Its high alkalinity boosts cleaning power and saponification of fats.
Cosmetics & Personal Care: Used in formulations where an alkaline pH is required or acceptable, such as certain hair relaxers, permanent wave solutions, and some bar soaps.
Textile Processing: Used in scouring and bleaching baths that operate under alkaline conditions.
Agriculture: In some agricultural chemical formulations.
Less Common in: Applications requiring neutral or acidic pH (where Disodium EDTA is preferred), or in biological/medical contexts where its high alkalinity is unsuitable.
