Disodium Hydrogen Phosphate Dihydrate (Na₂HPO₄·2H₂O)
Disodium Hydrogen Phosphate Dihydrate is the hydrated form of disodium hydrogen phosphate, a white crystalline powder commonly used as a buffering agent, emulsifier, and sequestrant. The dihydrate form contains two water molecules per formula unit, which affects its physical properties such as melting point and solubility. It is widely applied in food, pharmaceutical, water treatment, and industrial processes to maintain pH stability, improve texture, and supply essential sodium and phosphate ions.
Ferrous Sulphate Dried 150 Mesh
Ferrous Sulphate Dried 150 Mesh is a finely ground, dried form of ferrous sulfate (iron(II) sulfate) with a particle size passing through a 150 mesh sieve. It appears as pale green to light green crystalline granules or powder. This iron salt is widely used as a nutritional supplement, industrial chemical, and water treatment agent due to its high iron content (typically around 32-33% Fe) and enhanced solubility compared to the hydrated forms. The dried form improves stability and shelf life by reducing moisture content, making it suitable for applications in agriculture, pharmaceuticals, food fortification, and environmental treatment processes.
Iodised Salt
Iodised Salt is table salt (sodium chloride) fortified with a small, controlled amount of iodine, typically in the form of potassium iodate or potassium iodide. It appears as fine white crystalline granules, odorless, and with a characteristic salty taste. The addition of iodine helps prevent iodine deficiency disorders (IDD) such as goiter, mental impairment, and developmental abnormalities. Iodised Salt is widely used in households, food processing, and animal nutrition to ensure adequate dietary iodine intake.
L-Threonine Feed Grade
L-Threonine Feed Grade is a high-purity essential amino acid used primarily as a nutritional supplement in animal feed. It appears as a white crystalline powder and is vital for protein synthesis, growth, and overall health in livestock. This feed-grade form of L-Threonine helps balance amino acid profiles in animal diets, especially in monogastric animals like poultry and swine, improving feed efficiency and production performance.
Oleic Acid 75%
Product Description
Oleic Acid 75% is a naturally occurring monounsaturated fatty acid commonly derived from vegetable oils such as olive, sunflower, and canola oils. This oily liquid is widely used in the chemical, pharmaceutical, cosmetic, and food industries due to its excellent emollient, surfactant, and stabilizing properties. Oleic Acid 75% is a key raw material in manufacturing soaps, detergents, lubricants, and personal care products. Its amphiphilic nature makes it an effective emulsifier and penetration enhancer.
Vitamin K3
Vitamin K3, chemically known as Menadione, is a synthetic, fat-soluble vitamin used primarily in animal nutrition and some pharmaceutical applications. Unlike Vitamins K1 and K2, Vitamin K3 does not occur naturally but is a stable precursor that the body (or animal body) can convert into active forms of Vitamin K. It plays a critical role in blood clotting, bone metabolism, and cellular health. Vitamin K3 is usually available as Menadione Sodium Bisulfite (MSB) or Menadione Nicotinamide Bisulfite (MNB) for enhanced solubility and stability.
Xylanase Baking Enzymes
Xylanase Baking Enzymes are specialized enzymes used in the baking industry to improve dough handling, bread volume, crumb structure, and overall product quality. These enzymes catalyze the breakdown of xylans (non-starch polysaccharides in cereal cell walls), reducing dough viscosity and enhancing gas retention during fermentation. This results in improved texture, softness, and shelf life of baked goods.
Zinc Bacitracin Premix Feed Grade
