HP Span and Tween products

Span and Tween products are extremely mild, but very powerful multi-functional nonionic surfactants. Span HP is a range of sorbitan fatty acid esters while Tween HP is a range of polyoxyethylene sorbitan fatty acid esters (polysorbates). In contrast to standard, compendial-grade products, both HP ranges are suitable for a multitude of pharmaceutical applications particularly when additional purity is needed from your excipients.
