Super Refined™ excipients for topical drug delivery
Common issues affecting topical formulation include active pharmaceutical ingredient (API) instability, poor API solubilisation, and skin irritation that can lead to reduced patient compliance. Our Super Refined excipients address these formulation concerns and maximise the value of your topical drug product.
High purity excipients for topical drug delivery
Our proprietary Super Refining process yields highly purified excipients that can maximise drug product value and are indicated to stabilise, solubilise and optimise the active ingredients in the formulation.
Maximising API stability
To demonstrate enhanced API stability, we monitored the percentage of the API lidocaine that could be recovered over time when incorporated into Super Refined Crodamol™ OO (oleyl oleate) versus standard compendial oleyl oleate. It can be seen that lidocaine maintains its integrity and stability far better in Super Refined Crodamol OO, with significantly less API being recovered from standard compendial grade oleyl oleate.
Maximising oxidative stability
To demonstrate oxidative stability, the peroxide value of Super Refined Crodamol OO was compared to standard compendial grade oleyl oleate over a 40 day study in accelerated ageing temperatures. It was noted that the Super Refined excipient maintained a low peroxide value while the standard compendial grade exhibited an approximate 70-fold increase in peroxide value, indicating that it has undergone significant primary oxidation.
