Polysorbate 80 | Polysorbate 20 | polysorbate 80 uses | polysorbate 80 uses in pharmaceuticals

Mntafraid915 Jun, 2022Business

Polysorbates are derived from ethoxylated sorbitan (a derivative of sorbitol) esterified with fatty acids and exist as oily liquids. These Polysorbates belong to the class of emulsifiers used in pharmaceuticals and food preparations (salad dressing, ice cream, chocolates, baked goods and confectionery). They are used in cosmetics to solubilize essential oils into water-based products, pharmaceuticals, detergents, paints, and plastic applications. These Polysorbates surfactants consist primarily of oleic, stearic or lauric fatty acid esters with sorbitol-derived cyclic ethers (sorbitans and sorbides) and further polymerized with approximately 20 molecules of oxirane per molecule of Polysorbates.

What is ethoxylated alcohol or alcohol ethoxylate or ethoxylation of alcohol?

Mntafraid915 Jun, 2022Business

Alcohol ethoxylates belong to the class of compounds which are synthesized via the reaction of a fatty alcohol and ethylene oxide, resulting in a molecule that consists of two parts one a carbon-rich, fatty alcohol and the second part a hydrophilic, polyoxyethylene chain. This dual structural aspect of ethoxylated alcohol containing a hydrophobic portion (water-hating) with a hydrophilic component (water-loving), enables them to mix and solubilize oil and water by lowering the interfacial energy associated between them. These properties of ethoxylated alcohol gives them the general connotation of Surfactants or surface active agents.

An emulsifier is an additive which helps two liquids mix. For example, equal amounts of water and oil when poured in a glass tend to separate after some time, but adding an emulsifier will help these liquids mix. This process of mixing two immiscible phases like oil and water using an additive to form one phase after mixing is called emulsification. Two liquids can form different types of emulsions. For example, oil and water can form, first, an oil-in-water emulsion, in which the oil is the dispersed phase, and water is the continuous phase. Secondly, when water is the dispersed phase and oil is the continuous phase they can form a water-in-oil emulsion (see Figure 1). Therefore technical explanation of the word emulsifier is applicable mostly when both phases, dispersed and continuous, are liquids. For solid emulsions/dispersions the term colloids is often used. Some natural examples of emulsifiers are egg yolks and mustard sauce.

Dioctyl sodium sulfosuccinate | Docusate sodium | Sulfated fatty alcohols

Mntafraid915 Jun, 2022Business

Sulfated fatty alcohols are produced by the process of ethoxylation and sulfonation on fatty alcohols. Fatty alcohols are derived from natural sources like palm kernel oil, coconut oil, rapeseed oil, castor oil etc. Sulfated fatty alcohols have excellent emulsifying, wetting, lime soap dispersing and foaming properties. They also have high electrolyte tolerance. Alkyl ether sulphated (ethoxylates) also show improved water solubility and resistance to hardness. These products are widely used in emulsion polymerization, cosmetic formulations, detergents and textile industry. We offer a variety of sulphates based on natural and synthetic alcohols and ethoxylates. One, of our seven plants, has an exclusive facility for sulfonation using Oleum and other sulphating agents.

Define Nonionic surfactant or ethoxylated nonionic surfactant?

Mntafraid915 Jun, 2022Business

Nonionic surfactant refers to the surfactant molecules, which do not undergo ionization when being dissolved in water. The Nonionic surfactant are not in the ionic state in the solution, thereby having high stability and being less susceptible to the effect of strong electrolyte inorganic salts as well as acid and alkalis. Nonionic surfactants have excellent compatibility with other types of surfactants and have excellent solubility (which vary depending on different structures, HLB etc) in both water and organic solvents.

The compound that lower the surface tension between two phases, like between two liquids, a gas and a liquid, or a liquid and a solid are called surface-active agent or surfactant. In aqueous solutions surfactants behave like organic compounds that are amphiphilic, meaning they contain both hydrophobic groups (their tails) and hydrophilic groups (their heads). The arrangement of the hydrophilic head is at the interface of water and the hydrophobic groups aligns toward oil. Therefore, a surfactant contains both a water-insoluble (or oil-soluble) component and a water-soluble component. Surfactants will diffuse in water and adsorb at interfaces between air and water or at the interface between oil and water, in the case where water is blended with oil. This property allows surfactants to act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants.
