  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 natural raw materials to bring you t...

  Are sulfate and sulfonate the same thing in shampoo sulfate 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 ...

  What is hydroxyproline   Description L-4-Hydroxy Proline, (also referred to as Hydroxy Proline or Hydroxyproline), is an amino acid, a building block of protein, made by modifying another amino acid called Proline. It is the primary component of collagen, a fibrous protein found in the dermis of the skin that gives skin its structural support and youthful firmness. Collagen is also the major component of connective tissue, the material that provides structural report for most organs in the body. In the skin, collagen is synthesized by cells called fibroblasts. This process requires vitamin C. Hydroxyproline also plays an important role in wound healing and is a vital component of bones and teeth.   Hydroxy Proline is a major component of the protein collagen. Hydroxy Proline and proline play key roles for collagen stability. l hydroxyproline for skin   is found in few proteins other than collagen. For this reason, hydroxyproline supplement   content has been u...

  What is the difference between ionic and nonionic surfactants   Nonionic surfactant that does not generate ions in aqueous solution. Its dissolution in water is due to its strong affinity for water.   Compared with anionic surfactants, ionic non ionic   surfactants have a higher emulsifying ability and a certain resistance to hard water. It is an indispensable ingredient in detergent and emulsifier formulations. Of course, compared with anionic surfactants, non-ionic surfactants also have the disadvantages of limited cloud point, poor alkali resistance, and high price.   ionic vs non ionic   are mostly liquid and slurry, and their solubility in water decreases with increasing temperature. Non-ionic surfactants have various properties such as washing, dispersing, emulsifying, wetting, adding liquid, uniform dyeing, antiseptic, protective colloid and so on. Widely used in textile, paper, food, plastic, leather, fur, glass, petroleum, chemical fiber, medicin...
