a cyclodextrin derivative containing 12 methyl groups in average in a molecule in a random pattern. Similarly to tensides it has good solubilizing effect therefore utilized for solubilization, mobilization of soil contaminants and for the improvement of their bioavailability. Its solubilizing capacity is usually higher than that of the hydroxypropyl beta-cyclodextrin, but its biodegradation in the soil is slower (the half life time in the soil is 1-1.5 year). It is not harmful for the soil microflora, it has rather a beneficial effect by improving the availability of the nutrients of the microbes. It is harmless for humans as well, used as excipient in drugs, cosmetics and foods.
