11. Case Study 3-Successful reformulation of a natural product for the export market Client :UK based SME. Challenge: To enhance the solubility and improve the odour of a natural product formulation. Outcome: A technology for water soluble and de-odourised material was developed allowing for easy formulation in a number of ways, liquid, gel and bio-adhesive patch. Patent filed and technology transferred. De-odourised product launched in overseas market. Timelines: 6 months. Problem Solving: A novel and patentable technology was developed. Relationship: A strong relationship was developed with the client which involved a number of follow-on projects and a Knowledge Transfer Partnership was established. WATER SOLUBLE PROPOLIS NOW AVAILABLE IN THE KOREAN MARKET PROPOLIS GEL PROPOLIS PATCH http://www.bradford.ac.uk/research/rkt-centres/pharmaceutical-engineering/

12. Case Study 4-Succesful reformulation of an unstable topical product containing a strong oxidizing agent Client : European based SME. Challenge: To reformulate a topical formulation which had poor stability due to the presence of an oxidising agent. Outcome: A simple process was developed which did not require organic solvent, complex equipment and made technology transfer much easier and gave a product that had no stability issues. Progressed to IP protection and preclinical trials. Timelines: 4 months Problem Solving: A number of approaches where investigated including microencapsulation before a novel liquid crystal phase formulation was developed. Flexibility: Constant review and communication with client to modify and shift the project focus as necessary. http://www.bradford.ac.uk/research/rkt-centres/pharmaceutical-engineering/

14. Case Study 6-Identification of the problem and reformulation of a commercial product Client : European based SME. Challenge: To reformulate a commercial product with bioadhesivity and irritation problems. Outcome: New technology was developed exploiting the fundamentals of crystallisation and precipitation which enabled the preparation of an irritant free formulation. Scale-up and product performance trials in human volunteers and a patent application followed. Timelines: 9 months. Problem Solving: Investigations focused on the root cause of the problems with the aim of understanding of the fundamental processes, with this information it was then possible to resolve the issues allowing successful reformulation of the product. Costing: The original pricing was maintained over the 9 months project. http://www.bradford.ac.uk/research/rkt-centres/pharmaceutical-engineering/
