Method for reducing surface oil on encapsulated material

摘要

A method is provided for removing surface oil from a surface of an encapsulated material without using any type of solvent. The method includes contacting an encapsulated material having a moisture content of about 1 to about 60 weight percent with at least about 5 weight percent of an oil removing material for an amount of time effective for reducing surface oil on the encapsulated material by at least about 80%. In an important aspect of the application, the oil removing material is SiO 2 .
