Açıklama
Ethylenediaminetetraacetic Acid Disodium, commonly known as EDTA-2Na for short, is a widely used chelating agent in detergents, personal care products, and cosmetics. It effectively binds to iron (Fe2+/Fe3+) and calcium ions (Ca2+), forming water-soluble complexes in an aqueous solution, thus preventing these metal ions from bonding to the surfactants, which are commonly ionic in cleaning formulas. In this way, EDTA-2Na contributes to softening the water and maintaining the effectiveness of the surfactant.
EDTA-2Na also features outstanding sequestering ability and bacteria-inhibiting ability to improve the stability of the products in the air to increase their shelf life.
QUCIK DIRECT partners with the leading EDTA-2Na producer by a Third-party Commissioned Production Agreement to supply top-quality EDTA-2Na at a competitive price, with a 500 MT/ Month capacity.
Features & Benefits:
- Highly effective in chelating metal ions to maintain the activeness of the surfactants used in detergent, personal care, and cosmetic formulas.
- Outstanding sequestering ability and bacteria-inhibiting ability to improve the stability of personal care products and cosmetics in the air, so to increase their shelf life.
- Super stable quality, as produced by appointed leading producers.
- Steady supply, as guaranteed by long-term supply agreement.
Stability/Shelf life:
Stabe under proper storage.
Store in a cool, dry and ventilated place; Avoid direct sunlight.
Under proper storage conditions, the shelf life of QUCIK DIRECT EDTA-2Na is 24 months.
Recommended dosage:
The recommended dosage in detergents, personal care products, and cosmetics is 0.1%~1.0%.
