  I s P otassium I odide S oluble Potassium iodide is a white cubic crystal or powder. Potassium iodide is slightly hygroscopic in moist air. Potassium iodide precipitates free iodine for a long time and turns yellow, and can form a trace amount of iodate. Light and moisture can accelerate decomposition.   1 g of potassium iodide can be dissolved in 0.7 ml of water, 0.5 ml of boiling water, 22 ml of ethanol, 8 ml of boiling ethanol, 51 ml of absolute ethanol, 8 ml of methanol, 7.5 ml of acetone, 2 ml of glycerin, and about 2.5 ml of ethylene glycol. Its aqueous solution is neutral or slightly alkaline and can dissolve iodine. The aqueous solution will also oxidize and change to a yellow color, which can be prevented by adding a small amount of alkali. Its relative density is 3.12, the melting point is 680 ℃, and the boiling point is 1330 ℃. Its approximate lethal dose (rat, vein) is 285 mg/kg. It is widely used in the volumetric analysis of iodometric methods to prepare titran...

  F lavor F rangance I ngredients They can be found in food, wine, spices, floral scent, perfumes, fragrance oils, and essential oils. Also, many of the aroma compounds play a significant role in the production of flavorants, which are used in the food service industry to flavor, improve, and generally increase the appeal of their products.   Flavors: Flavors affect both the sense of taste and smell, whereas fragrances affect only smell. Flavors tend to be naturally occurring, and fragrances tend to be synthetic.   They can be found in food, wine, spices, floral scent, perfumes, fragrance oils, and essential oils. Also, many of the aroma compounds play a significant role in the production of flavorants, which are used in the food service industry to flavor, improve, and generally increase the appeal of their products.   Cutting-edge flavours, seasoning blends and a unique expertise for designing sweet to savoury products, combined with an unrivalled knowledge of natu...

  D ifference B etween E mulsifier and S urfactant Surfactants are substances that contain hydrophilic and hydrophobic bases.   Surfactants refer to substances that have a fixed hydrophilic and oil-friendly group that can be orientated on the surface of the solution and can significantly reduce surface tension.   An emulsifier is a surfactant and can also be used as a penetrant. The surfactant has the function of emulsification, but also other functions.   The main functions of the surfactant are: stain removal, emulsification, solution, suspension, bubble elimination, sterilization and so on. There are many kinds of surfactants. According to the use classification, there are emulsifiers, antistatic agents and detergents, stabilizers, defoaming agents, dispersants, etc. These uses can be distinguished according to the size of the HLB value. Surfactants have a large range and contain surfactants and emulsifiers . The HLB value of the surfactant is between 0-40, while ...

  W hat I s S ulfonate ? S ulfate and sulfonate   have two things in common. First, they're all anionic surfactants. Second, they are often used for personal care applications. But there are many differences. They have different molecular mechanisms. They have different functions and they have different raw materials.   Sulfates Sulfate is a compound. It has carbon bonds and oxygen and sulfur bonds. They include substances such as sodium lauryl sulfate and sodium lauryl ether sulfate.   At low pH, these substances plus the c-o-s bond hydrolyze to produce alcohol and inorganic sulfate. At a high pH, sulfate is stable in the base and, if ethoxylated to a relatively high level, produces a low-foaming alkali-soluble surfactant. Sulphates can be prepared by reaction of fatty alcohol or fatty alcohol ethoxylates with reagents such as SO3 or chlorosulfonic acid (CSA).   The reason shampoo becomes thick foam in the shower is that it contains sulfate. Most shampoos and h...
