VWR Polysorbate 80, part of the GPR RECTAPUR® line, is a high-quality, non-ionic surfactant commonly used for solubilization, emulsification, and dispersion in analytical chemistry, pharmaceutical formulation, and biochemical applications. It offers excellent wetting and stabilizing properties, and is supplied with low levels of heavy metals and evaporation residue, making it suitable for high-purity laboratory use.
Also known as Tween® 80, Polysorbate 80 is widely utilized as a solubilizing agent for lipophilic substances, emulsifier in oil-in-water systems, and stabilizer in formulations requiring biocompatibility and chemical consistency.
