Abstract: The gel compositions as described herein, are less affected by changes in humidity, are readily formed into complex shapes, and can contain high loadings of the hydrophobic material, even when the material is not highly hydrophobic, and provide a more controlled release of the hydrophobic material. It is believed that the slow release is achieved by forming the gel to have a tight cross-linked network with small pore-size. The pore size is correlated to the average correlation length as measured using Small Angle X-Ray Scattering (SAXS). By limiting the average correlation length to less than 8 nm, preferably from 0.3 nm to 8 nm, more preferably from 0.3 nm to 4 nm, a long lasting release of the hydrophobic material is achieved, rather than a blooming effect, whereby the hydrophobic material is released in a short burst.
