Polysorbate 80 VS. Polysorbate 20: What's the Difference

In everyday products like food, pharmaceuticals, and cosmetics, additives are vital. Polysorbate 80 and Polysorbate 20, both surfactants, are commonly encountered. Despite their similar names, they have distinct applications. This article will elucidate the disparities between Polysorbate 80 and Polysorbate 20, aiding in better understanding their utility in different contexts.

What are Polysorbates?

Polysorbates are a group of synthetic emulsifiers widely used in the food and cosmetic industries. They are derived from sorbitol, a sugar alcohol, and ethylene oxide. Polysorbates are characterized by their ability to lower the surface tension between ingredients, which helps to stabilize mixtures of oil and water.

Polysorbates can function as emulsifiers, stabilizers, and solubilizers. The most commonly used polysorbates are Polysorbate 20, Polysorbate 40, Polysorbate 60, and Polysorbate 80, each differing in the number of ethylene oxide units attached.

What is Polysorbate 80?

Polysorbate 80 for sale is also referred to as polyoxyethylene (20) sorbitan monooleate. It is a nonionic surfactant and emulsifier extensively utilized across numerous industries, such as food, cosmetics, and pharmaceuticals. Similar to other polysorbates, it is produced through the chemical reaction between sorbitol (sugar alcohol) and ethylene oxide. The "80"  indicates the type of fatty acid ester (oleic acid) used in its synthesis.

Polysorbate 80 e433 excels at mixing water and oil-based substances, making it crucial in processed foods like ice cream, salad dressings, and baked goods. It also serves as a stabilizer in vaccines and medicines, ensuring even distribution of active ingredients.

What is Polysorbate 20?

Polysorbate 20 for sale is known as polyoxyethylene (20) sorbitan monolaurate. The "20" in its name indicates that it contains 20 units of ethylene oxide per molecule. Polysorbate 20 is a nonionic surfactant and emulsifier derived from the chemical reaction of sorbitol, a sugar alcohol, and ethylene oxide. It is part of the larger group of polysorbates, which are used to help blend and stabilize ingredients that typically do not mix well, such as oil and water. Polysorbate 20 emulsifier is mainly used in cosmetic and personal care products.
