Applications
- Industrial water treatment: scale inhibition and metal ion control in cooling towers and boilers.
- Household and industrial cleaning formulations: improves detergency by sequestering hard water ions.
- Personal care products: stabilizes formulations in shampoos, soaps, and skin creams.
- Textile processing: removes metal ions during scouring and dyeing to prevent shade variations.
- Pulp and paper: chelates metal ions to enhance brightness and reduce pitch.

Frequently Asked Questions
Q: What is the primary industrial application of CAS 16455-61-1?
A: EDTA Disodium Salt Dihydrate is primarily used as a chelating agent in water treatment systems to prevent scale formation and corrosion by sequestering calcium, magnesium, and iron ions. It is also essential in cleaning and personal care products to stabilize formulations and enhance performance.
Q: What are the standard packaging options for bulk orders of this chemical?
A: For bulk orders, this chemical is typically packaged in 25 kg paper or woven polypropylene bags, palletized for safe transport. Large-volume purchasers can request 500 kg or 1000 kg FIBC jumbo bags. All packaging is tailored to protect the product’s crystalline integrity and prevent moisture ingress.
