  1. Low foaming nonionic surfactants Detergent is a very broad term; it includes various kinds of industrial detergents and commercial detergents. Commercial detergent is the most common type of detergent for consumers. Besides the strength of detergency and cleaning efficiency, the property of low foaming has become an important aspect in developing both commercial and industrial detergents.   2. The advantages of low foaming surfactants In industrial scale cleaning, having too much foam means more water and electricity are needed to remove the foam and thus increase in cost. Furthermore, operation speed, efficiency and service life of certain facilities and equipment might decline due to long period of time soaking in foam and detergents. A balance between detergency and foam can be achieved by adapting low foaming nonionic surfactant in detergent formulation. Low foaming nonionic surfactants have great surface activity, detergency, wettability, dispersancy and lubrici...

  Synthetic Raw Materials Difference between  Polysorbate 20 and 80 W hat is the difference between polysorbate 20 and 80 ？ W hat is polysorbate 20 made from ？ Polysorbate 20 is a product of the polymerization reaction of sorbitan monolaurate and ethylene oxide, while polysorbate 80 is synthesized by the polymerization of sorbitan monooleate and ethylene oxide.     P olysorbate 20 or 80   Application : Polysorbate 20  is known as a non-ionic stain remover because it has relatively more hydrophilic groups (polyoxyethylene), which gives it a strong hydrophilicity property. P olysorbate 20 us e ： Polysorbate 20 is used as an oil-in-water(O/W) type emulsifier and solubilizer.   Polysorbate 20 uses in cosmetics     Polysorbate 80 is one of the most common polysorbates. The polysorbate 80 emulsifier  has significant resistance to electrolyte and strong hydrophilicity, which allow it to be widely used in liquid, semisolid and solid preparations...

  ionic vs nonionic surfactant W hat is the difference between ionic and nonionic surfactants   . The main difference between ionic and nonionic  is that ionic surfactants are formulated with cations or anions, while non-ionic surfactants are formulated without cations or anions.   What is Non-ionic Surfactants? Non-ionic surfactants are surfactants whose main hydrophilic groups are the ether groups, which are not dissociated in an aqueous solution. Their surface activities are dependent on the neutral molecules. Non-ionic surfactant   list , such as the  ethoxylated sorbitol  and  sorbitan fatty acid ester , all have high surface activity, good solubilizing and cleansing properties, antistatic function, calcium soap dispersion etc. They have excellent wetting functions and relatively minor irritation. They can be used in a wider PH range than of ordinary ionic surfactants. Meanwhile, they can be used together with other ionic surfactants. That is...

  The problem of pharmaceutical excipients has plagued domestic pharmaceutical preparation manufacturers in recent years, and the quality control of excipients has attracted the attention of regulatory agencies and manufacturers. There are specific requirements for physical and chemical testing indicators of the excipient varieties in Chinese Pharmacopoeia, and studies related to the testing of excipients which have been carried out. Here is a case to share with you: polysorbate 80 fatty acid testing.   Polysorbate 80 composition   is a natural non ionic surfactant , which is a polyoxyethylene 20 sorbitan oleate polymerized from sorbitan oleate and ethylene oxide. Because polysorbate  80 has a good solubilizing effect on lipophilic drugs, it is often used as a solubilizer or emulsifier for injections and oral liquids and is a commonly used excipient for pharmaceutical preparations. Polysorbate 80 is usually a mixture, and the composition of the fatty acid part in its...

  Sorbitan esters are widely used in various food formulations in multiple countries around the world. The importance is sorbitan monostearate safe . The safety of sorbitan esters have been evaluated and approved by many countries’ food safety authorities. Sorbitan monolaurate, sorbitan monopalmitate, sorbitan monostearate, sorbitan tristearate and sorbitan monooleate are approved to be used as food additives in China, the United States, the European Union, Japan and more. Sorbitan esters are well studied and have been used in food manufacturing for several decades.  Using sorbitan esters that are up to the regulation standards with the appropriate dosages, are non-toxic and safe to be consumed. The following specifications are the critical criteria that determines the quality of sorbitan esters saponification number, acid number, hydroxyl number and oxyethylene content. It is important for food manufacturing companies to seek for suppliers that are qualified to ensure the saf...

  WHAT IS HLB ? HLB value is the abbreviation for hydrophilic-lipophilic balance, it is the ratio between the hydrophilic portions and lipophilic portion of a surfactant. It is represented by a number between 1 and 20. An HLB value less than 6 indicates that the surfactant favors W/O emulsion; an HLB value greater than 8 favors O/W emulsion. HLB values in between 7 and 9 indicate that the surfactants are good wetting agents. Huana  has been professionally concentrated on Sorbitan  Esters & Polysorbates since 1993, with decades of R&D and production experience.
