Etidronic Acid 60% / Terpinal SL / HEDP 60 %

Description

Etidronic Acid 60%, Terpinal SL, and HEDP 60% are all the same chemical compound, 1-Hydroxyethylidene-1,1-Diphosphonic Acid (HEDP), specifically a 60% aqueous solution. It’s an organophosphonic acid and a chelating agent, widely used in water treatment, cleaning agents, and personal care products. Cosmeti Hub Online Chemical Solution +2
Here’s a more detailed breakdown:
1. Chemical Identity:
HEDP stands for 1-Hydroxyethylidene-1,1-Diphosphonic Acid.
It’s an organophosphonic acid and a chelating agent.
The “60%” refers to the concentration of HEDP in the solution, meaning it’s a 60% active aqueous solution.
“Terpinal SL” is a trade name for HEDP.
2. Key Properties and Functions:
Chelating Agent:
HEDP binds to metal ions (like calcium, magnesium, and iron) in water, preventing them from forming scale and corrosion.
Scale and Corrosion Inhibitor:
By sequestering metal ions, HEDP inhibits the formation of scale and corrosion in water systems like cooling towers and boilers.
Antioxidant Effects:
It acts as an antioxidant, particularly as an iron chelator.
Threshold Inhibitor:
HEDP can act as a threshold inhibitor, preventing crystal growth and precipitation of mineral salts.
