*A very small amount of PVA/clay was added to each vial and the vial was filled with safflower oil prior to the rapid freezing in order to achieve a true emulsion of microspheres in the organic safflower oil. This may prevent the formation of hydrogels. | *A very small amount of PVA/clay was added to each vial and the vial was filled with safflower oil prior to the rapid freezing in order to achieve a true emulsion of microspheres in the organic safflower oil.
