Tween 80

What is Tween 80? Also known as Polysorbate 80, it is a non-ionic surfactant and emulsifier, commonly utilised in various scientific, pharmaceutical, and industrial applications. It is a pale yellow, viscous liquid with a mild odour. It functions to lower the surface tension of liquids, facilitating the mixing of water with other substances, particularly oils and lipids. It is synthesised from sorbitol (a sugar alcohol) and ethylene oxide, and is valued for its ability to stabilise emulsions, solubilise hydrophobic compounds, and improve the texture of products. It is a widely used compound in both laboratory and industrial settings due to its versatility and efficacy.
