Abstract
Cyclodextrin compositions, including a hydrophobic carrier and a cyclodextrin complex, are formed and disposed on a variety of substrates using conditions that avoid substantial loss of the complexed compound from the cyclodextrin complex, even where the complexed compound is a gas a common ambient temperatures (e.g. 20° C.). Flexographic printing is particularly useful for disposing the cyclodextrin compositions on one or more substrates. Substrates treated with the cyclodextrin complexes are useful for subsequent release of the complexed compound.
Claims16
A composition consisting essentially of
- a cyclodextrin inclusion complex comprising a cyclodextrin compound and an olefinic inhibitor;
- and
- a carrier,
- wherein the carrier has a melting transition onset between about 23° C. and 40° C. and solubility in water of less than 1 wt % at 25° C.
