Through our R&D team based in our subsidiary Drug Delivery
Solutions Ltd. in Leatherhead, South East of London we have
pioneered and developed polyaphron science for use as the basis of
proprietary drug delivery vehicles.
Polyaphrons are oil-in-water or water-in-oil dispersions of
colloidal dimensions that have foam like properties and related to,
but significantly different from conventional emulsions.
We use our expertise and proprietary technology to solve
challenging formulation and drug delivery tasks and to broaden the
variety of ingredients and API's that can be included in
pharmaceutical formulations, while at all times ensuring that the
final products are safe and comfortable to use for the
end-user.
The applications of our Polyaphron
Dispersion Technology are many and include the
following:
The team is lead by Managing Director of our Leatherhead R&D
site, Derek Wheeler, our Technical Director Stephen Lenon and Dr.
Frazer Steel, Principle Scientist.
Ph.D., Technical
Director
Stephen Lenon is the Technical Director of the R&D team. He
graduated with a first class degree in Applied Chemistry from
Salford University in 1978 and has been awarded both an MSc and PhD
in Colloid Science by Bristol University.
He worked for many years with ICI before joining Disperse/DDS in
2000. He is an expert in dispersion and colloid science and has
extensive knowledge of both solvent-borne and water-borne polymer
synthesis.
Dr Lenon is a committee member of the Society of Chemistry and
Industry and the author of several patents.
MSc, Managing
Director
Derek Wheeler is one of the founders of DDS and acts as CSO.
After obtaining degrees in Chemistry and Physiology at London
University in 1963 he began a career in analytical chemistry,
product formulation, process engineering, marketing and general
management for a number of major cosmetic and pharmaceutical
manufactures.
He founded Disperse Ltd. in 1997 to develop and exploit patents
on the polyaphrons dispersion technology.
Derek enjoys an international reputation as a leading dispersion
scientist and is a member of the Society of Cosmetic Scientists
where he is an examination question setter and marker.
He has been called as an expert witness and has widely written
and lectured on dispersion issues and is the author of a number of
patents.
Dr., Principle
Scientist
Dr. Fraser Steele joined DDS in 2005 and is Principal
Scientist.
Having previously worked as Research Fellow on applications of
the technology at the Victorian College of Pharmacy, Monash
University, Australia.
Dr Steele was awarded a PhD by the Department of Pharmacy and
Pharmacology, University of Bath in Amine/ Microcrystalline
Cellulose Interactions. He also holds a BSc(Hons) in Chemistry from
Loughborough University and a MPhil in Geological Sciences from
Liverpool University.
He is a Member of the Royal Society of Chemistry is a
co-inventor on a number of patents.
