Title:
NOOTKATONE OR NOOTKATONE ANALOG DERIVATIVES AND UTILIZATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2000/027907
Kind Code:
A1
Abstract:
Grapefruit extract and nootkatone (or its analogs) and nootkatone (or its analog) derivatives are usable in volume-reduction, dissolution and reuse of styrene foams (hydrocarbon polymer plastics such as polystyrene and polypropylene), eliminating oily stains, dissolution of cholesterol, etc. Compared with D-limonene, these substances can reduce the volume of a large amount of plastics (styrene foam, etc.) even in a small amount. Moreover, the resultant solutions containing plastics (styrene foam, etc.) dissolved therein can be easily post-treated at low temperatures. In addition, nootkatone (or its analogs) contained in grapefruit extract can be converted into nootkatone (or its analog) derivatives by chemical treatments and these derivatives show similar effects.
