What is Tween 20? Tween 20 (also known as Polysorbate 20) 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.
Consistent Quality: We use only carefully sourced Tween 20, ensuring consistent performance across various applications.
Shipped from Manchester, UK Facility: Sourced and bottled using non-toxic, chemical-resistant bottles, providing reliable and trusted quality to our customers.
Frequent Uses
Emulsification
Commonly used to stabilise emulsions, especially in pharmaceutical and cosmetic formulations. It aids in the consistent mixing of oil and water-based components, preventing separation and ensuring uniform product texture.
Molecular Biology
Frequently used in laboratory protocols, such as Western blotting and cell culture applications. It is effective in reducing non-specific binding and enhancing the performance of reagents in various biological assays.
