The Seeker is looking for a novel formulation that modifies the volatility of a biologically active compound to give a product with activity of more than one year. The formulation should be stable for several years of storage even under tropical conditions. The resulting formulation should be able to be applied by spraying or by brushing etc. after dilution with water on many surfaces. The Seeker requires that the formulation technique must use commonly available materials and state of the art manufacturing process, as well as be safe for humans and the environment.
This Challenge requires only a written proposal.
Sustained Release Formulation for Synthetic Pyrethroids
Detailed Description & Requirements
INTRODUCTION
The Seeker is keenly interested in finding a “new and novel” approach to formulation that will stabilize a volatile synthetic bioactive, for a full year after application via sprayed or brushed-on use scenarios, yet protected from its typical routes of decomposition. The formulation must be considered safe for humans and the environment, and it must be cost-effective to manufacture from commodity-type materials using state-of-the-art manufacturing processes.
DETAILS OF COMPOUND TO BE FORMULATED
The active the seeker is interested in belongs to the chemical class of synthetic pyrethroids (http://en.wikipedia.org/wiki/Pyrethrin). It has a molecular weight of approx. 400, a vapor pressure of about 1mPa at 25°C, a very poor solubility in water but high in non-polar media.
