abbreviated as HPBCD, a sugar derivative of good solubilizing capacity. By molecular encapsulation (inclusion complex formation) it can dissolve water-insoluble organic compounds, e.g. hydrocarbons in water. It is of ring shape molecule, a cyclodextrin unit with 3-6 hydroxypropyl substituents. It is utilized for mobilizing the organic pollutants in soil (→"sugar flushing" technology), for improving the bioavailability and biodegradability of these contaminants. HPBCD is fast biodegraded in soils (half life time is < 1 year). It is not harmful for the soil microflora, improves the availability of their nutrients. It is harmless for the humans as well, is used as pharmaceutical excipient and as an additive in various food products.
