Polysorbate 20 and 80 are non-ionic surfactants that are widely used in the pharma industry in oral, topical and injectable applications as well as blood fractionating, vaccine development and formulation. Standard compendial grade excipients contain impurities that can negatively influence formulations. Purity is a key factor for successful vaccine development. Our Super Refined™ Polysorbates have been developed to optimise the performance of pharmaceutical formulations, with reduced levels of impurities known to affect formulation stability. Cholesterol is another essential ingredient of adjuvants systems, in recent years there has been increasing demand for cholesterol from a plant-based source. Our plant-based and parental grade cholesterol provides a high-purity alternative to traditional egg and plant-based cholesterol and is USP/NF, JP and parenteral grade Ph. Eur compliant.
Our offering of high purity, multi-compendial excipients can also be used in formulations for Small Molecule Delivery and Protein Delivery.
Our Super Refined range of parenteral excipients solve even the toughest challenges associated with protein-based therapies, ensuring optimal protein stabilisation through our unmatched purity. Click here to learn more.
Our vast portfolio of pharmaceutical excipients also enhance small molecule drug delivery across a variety of administration routes and dosage forms

Surfactants and stabilisers
Surfactants and stabilisers play key roles in pharmaceutical applications, enhancing the performance and stability of formulations. Surfactants address formulation challenges and improve API solubility, stability and bioavailability, while stabilisers are key to preventing API degradation and extending the product's shelf life.
Discover our extensive offering of surfactants and stabilisers, including solubilisers, emulsifiers, anti-oxidants and chelating agents.
