Overview
Ethylenediamine dihydroiodide (EDDI) is a water-soluble salt derived from ethylenediamine and hydroiodic acid. It serves as a highly bioavailable organic iodine supplement for animal nutrition. EDDI is widely used in pet food, cattle feed, poultry feed, and mineral premixes to prevent iodine deficiency and support overall health. It is recognized by the FDA as generally recognized as safe (GRAS) as a nutrient source of iodine.

Key Benefits

• High bioavailability: Provides organic iodine that is readily absorbed and utilized by animals.

• Prevents iodine deficiency: Helps prevent goiter, reproductive disorders, and other iodine-deficiency conditions in cattle, sheep, and swine.

• Supports thyroid function: Maintains healthy thyroid metabolism across production cycles.

• Helps prevent foot rot: Used in cattle feed to assist in systemic prevention of foot rot and soft tissue lumpy jaw.

• Water-soluble: Easily integrates into liquid supplements, mineral blocks, and feed premixes.

• Cost-effective: Concentrated iodine content (≈79.5%) offers an economical alternative to inorganic salts.

Applications

• Cattle feed: Nutritional source of iodine; recommended intake limit of 50 mg/head/day.

• Pet food: Additive to prevent iodine deficiency in dogs and cats.

• Poultry feed: Supports metabolic regulation and growth.

• Veterinary use: Used as an expectorant, anti-inflammatory, and for chronic infections.

• Pharmaceutical intermediate: Used in the synthesis of veterinary medicines and topical antiseptic products.

Handling and Storage

• Store in a cool, dry place, away from heat and moisture.

• Keep containers tightly sealed to prevent moisture absorption.

• Use appropriate personal protective equipment (gloves, safety goggles, dust mask) when handling.

• Causes skin and eye irritation; avoid contact with eyes, skin, and clothing.

• In case of spillage, collect into container for disposal; flush with plenty of water.

Quality Assurance
Each batch is tested for iodine content, purity, heavy metals (lead, arsenic, cadmium, mercury), and loss on drying to ensure compliance with feed-grade standards.
