Excipients for protein therapeutic formulations

We understand the challenges faced by protein therapy manufacturers in developing formulations that maintain their stability and efficacy, such as protein aggregation. We develop high-quality excipients specifically designed to improve the stability, solubility and bioavailability of protein therapeutics. Our Super Refined™ excipients are manufactured to the highest standards of purity and quality, and undergo rigorous testing to ensure they meet the strict regulatory requirements expected for the parenteral administration route.

We offer a comprehensive portfolio of excipients to support the formulation of protein therapies, including stabilizers, surfactants, solubilizers and preservatives, to help you optimize your formulations and achieve long-term stability and efficacy. Our excipients undergo application testing to ensure their compatibility with a range of protein therapeutics, including monoclonal antibodies. Excipients are an essential component of protein formulations, and we are committed to providing innovative and reliable solutions to support your development and manufacturing needs. Our team of technical experts works closely with you to ensure that our excipients are always optimized for specific formulation requirements. Through our effective products and solutions, we are proud to contribute to the development of life-saving protein therapies that meet the needs of patients around the world.

Super Refined™ excipients for Protein Delivery

Our 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 and 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. 

We have a large variety of products, ranging from various polysorbates, polyethylene glycols (PEG), esters, vegetable oils, and more. 

Add significant value to your drug formulations today with our Super Refined range offering: 

  • Minimised API degradation
  • Reduced oxidation potential
  • Reduced impurities and allergic potential.

Minimised API degradation in protein drug delivery

Our Super Refined™ range can provide enhanced API stability.

A chemotherapy drug (docetaxel) was dissolved in both standard grade compendial and Super Refined™ PEG 400 and aged for 12 weeks at 40oC. The samples were analysed by HLPC at 0, 4, 8 and 12 weeks. 

After 12 weeks of accelerated aging the Super Refined™ PEG 400 showed over 90% drug recovery, in comparison to its standard compendial grade counterpart. Our Super Refined™ excipients minimise API degradation, offering you confidence in your formulation and optimising drug delivery. Order your sample today.

Reduced impurities and allergic potential in protein drug delivery

The Super Refining process results in reduced levels of impurities, such as formaldehyde, in our excipients. The presence of high levels of formaldehyde in excipients has been linked to API degradation, drug instability and cell membrane irritation. 

When compared to its standard compendial grade counterpart Super Refined™ Polysorbate 80 showed an 81% reduction in formaldehyde levels. The improved patient comfort associated with our Super Refined™ range aligns with Croda’s purpose to use smart science to improve lives, speak to our experts today and learn how our Super Refined™ range can work for you.
