  1. What is polysorbate 80? polysorbate hlb , the chemical name is polyoxyethylene 20 sorbitan monooleate, is a non-ionic surfactant, has significant adaptability to different pH, and is relatively stable when coexisting with high-concentration electrolytes. The water-lipophilic balance value ( polysorbate 80 hlb value ) is 15. It has strong hydrophilicity and is miscible with water, methanol, ethanol, chloroform and ethyl acetate. It is widely used in injections and oral preparations as O/W (water oil-in-oil) type emulsifier, solubilizer, wetting agent.   Studies have shown that when hlb polysorbate 80   reaches a certain critical micelle concentration, the hydrophobic parts of its molecules attract each other and combine to form micelles. The formed spheroids, the solubilized substances, combine with the micelles in different ways, thereby increasing the dissolution of the drug components, but the solubilization effect is different from the real dissolution effect. ...

  what is polysorbate 20 in skin care Understand polysorbate 20   One of the most commonly used variants of polysorbates in the cosmetics industry is polysorbate 20 uses in cosmetics . It is a monolaurate with a hydrophilic-lipophilic balance (HLB) of 16.7. The main ingredients of PS 20 are sorbitan monolaurate, fatty acids with an average alkyl chain length of 12 carbon atoms, and ethylene oxide (EO).   Applications of polysorbate in cosmetics   Polysorbate 20 for skin   is a nonionic surfactant that can be used in various cosmetics and personal care products. Due to its oily, liquid, and mild nature, PS 20 can be used as a nonionic surfactant and wetting agent, thus enhancing the spreadability of liquids. It is also commonly used as a solubilizer, as it can attach fragrances and essential oils to various types of cosmetic matrices. The substance prevents oil and base materials (such as cream, liquid, or gel bases) from separating. Polysorbate 20 is usually use...

  Ⅰ . Background and overview of polysorbate 60   Polysorbate 60, lemon to orange oily liquid or semi-gel, slightly special odor, slightly bitter. Polysorbate 60 is a non-ionic surfactant, which has been widely used in food, daily chemical, medicine, mechanical processing and other fields. There are two kinds of synthesis methods: one-step method and two-step method. The products produced by the traditional one-step alkali catalysis method contain various by-products such as diesters and triesters, which are dark in color and unstable in quality. They can only be used for petroleum, washing and textile industries. The two-step method is divided into two types: first etherification followed by esterification and first esterification followed by etherification. The color of the product obtained by first etherification and then esterification is black, the content of diester and triester is high, and the quality and performance are poor; The product obtained by the...

  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.   For more information about sorbitan ester , please feel free to contact us!   Guangdong Huana  Chemistry Co., Ltd. is a professional global chemical engineering company based in China.
