The product, High Quality Polysorbate 20/Tween 20 with CAS number 9005 - 64 - 5, is a well - known non - ionic surfactant. Its chemical formula is C₅₈H₁₁₄O₂₆. This product usually appears as a yellow to amber, oily, viscous liquid with a characteristic odor.
It has excellent solubility in water, ethyl alcohol, and ethyl acetate. With a molecular weight of approximately 1227.53 g/mol, it offers high purity and meets high - quality standards. The product is available at the best price in the market, providing great value for customers in various industries.
Polysorbate 20/Tween 20 has a wide range of applications. In the pharmaceutical industry, it is commonly used as an emulsifying agent in the formulation of oral, topical, and parenteral drugs. It helps to create stable emulsions, improving the solubility and bioavailability of poorly soluble drugs. For example, in some oil - in - water emulsions for intravenous injections, Polysorbate 20 ensures uniform distribution of the oil phase in the water phase, preventing phase separation.
In the food industry, it serves as an emulsifier, stabilizer, and dispersant. It can be found in many food products such as ice cream, salad dressings, and beverages. In ice cream, it prevents the formation of large ice crystals, resulting in a smoother texture. In salad dressings, it helps to keep the oil and water phases mixed, improving the product's shelf - life.
In the cosmetic industry, it is used in creams, lotions, and shampoos. It acts as an emulsifying agent to combine oil and water components, and also as a solubilizer for essential oils and other hydrophobic ingredients. This ensures a uniform and stable product with good spreadability.
When using Polysorbate 20/Tween 20, the proper dosage should be determined according to the specific application. In general, in pharmaceutical formulations, the concentration can range from 0.1% to 10%. In food products, it should comply with the relevant food safety regulations, usually in the range of 0.05% - 2%.
To use it as an emulsifier, first, add Polysorbate 20 to the oil phase and mix well. Then, slowly add the water phase under high - speed stirring. Continue stirring until a stable emulsion is formed. When using it as a solubilizer, dissolve the hydrophobic substance in Polysorbate 20 first and then add water to form a clear solution.
Case 1: Pharmaceutical Emulsion
A pharmaceutical company was developing a new oil - in - water emulsion for a topical anti - inflammatory drug. They initially had problems with the stability of the emulsion, with the oil phase separating quickly. After adding 2% Polysorbate 20 to the formulation, they found that the emulsion remained stable for several months at different storage temperatures. The drug's effectiveness was also improved due to better dispersion of the active ingredient, resulting in more consistent therapeutic outcomes.
Case 2: Food Product - Ice Cream
A small ice cream manufacturer was facing issues with the texture of their ice cream. Large ice crystals were forming, making the product less appealing. By adding 0.1% Polysorbate 20 to the ice cream mix, the ice cream became smoother and creamier. The product's sales increased significantly as customers preferred the improved texture.
Case 3: Cosmetic Lotion
A cosmetic brand was formulating a new moisturizing lotion. They had difficulty combining the oil - based and water - based ingredients. After incorporating 1% Polysorbate 20, the lotion had a homogeneous appearance and a pleasant feel on the skin. The product received positive feedback from consumers and had good market performance.
