Why choose Super Refined ingredients?

Selection of the right excipient which is compatible with both your drug and your formulation can mean the difference between a blockbuster drug and a failed drug. Many excipients come with a variety of impurities and byproducts which can hinder product performance and cause formation of potentially dangerous and toxic degradants.

Super Refined excipients are stripped of a number of oxidative impurities, such as peroxides, aldehydes, and catalyst residues. The removal of these problematic species helps to reduce negative API & excipient interactions, maintaining both the stability of the drug and the final formulation.  In addition, the removal of these impurities can minimise cellular irritation, reduce taste impact, and potentially decrease allergenicity.

Additionally, many of our products meet the needs of multiple monographs such as the USP/NF, Ph. Eur,, JP/JPE, and ChP.

Drugs can be inherently unstable, and readily react with impurities found in excipients. This can lead to formation of side products, thereby reducing drug efficacy. Using Super Refined™ ingredients not only ensures that your drug will remain stable in solution, but can also make analysis of the product significantly easier.
