GMP grade polysorbates for Nucleic Acid Delivery

Polysorbates are non-ionic surfactants and emulsifiers commonly used in the pharmaceutical industry to promote API absorption and prevent the formation of aggregates and precipitation.

Polysorbates such as Tween are also commonly used to formulate lipid-based gene carriers. Playing a key role in these formulations as emulsifiers and stabilisers polysorbates also have an active role in the integration of DNA and therefore promote gene expression1.

We have a wide offering of compendial, high purity and Super Refined™ polysorbates to suit your formulation needs, explore our offering below!
