  • It is a white crystalline powder which does not change its colour after 90 minutes heating at 1050C. It has a melting temperature of 133-1350C and its solubility in water at 250C is 1380 g/l.

  • E477 is derived from glycerol, a naturally occurring compound found in fats and oils. It is produced through the process of esterification, where glycerol reacts with fatty acids. This process creates a versatile compound that can interact with both hydrophilic (water-loving) and hydrophobic (fat-loving) substances, allowing it to effectively stabilize emulsions. The unique properties of E477 enable it to function as an emulsifier, thickener, and stabilizer in various formulations.


  • When using magnesium sulphate as a fertilizer, it is crucial to apply the right amount at the right time. The typical application rate varies based on soil tests and specific crop needs, but a general guideline is to apply 10 to 50 pounds per acre, depending on the severity of magnesium deficiency.


  • The Food and Drug Administration (FDA) reviewed the safety of Sorbic Acid and Potassium Sorbate and determined that they were Generally Recognized As Safe (GRAS) as preservatives for direct addition to food. Sorbic Acid and Potassium Sorbate are effective for the control of mold and yeast in cheese products, baked goods, fruit juices, fresh fruits and vegetables, wines, soft drinks, pickles, sauerkraut, and certain fish and meat products. The safety of Sorbic Acid and Potassium Sorbate has been assessed by the Cosmetic Ingredient Review (CIR) Expert Panel. The CIR Expert Panel evaluated the scientific data and concluded that Sorbic Acid and Potassium Sorbate were safe for use in cosmetics and personal care products. In 2006, as part of the scheduled re-evaluation of ingredients, the CIR Expert Panel considered available new data on these ingredients and reaffirmed the above conclusion.

  • 2-Butyne is a colorless gas at room temperature and pressure. It has a boiling point of around 25.1 °C and a melting point of approximately -100.8 °C. Its density is greater than that of air, which means that it can accumulate in low-lying areas, posing potential hazards if not handled properly. The compound is flammable and should be stored away from ignition sources.
