  • Oil-containing solid product and process for producing the same
    Publication number: 20090081292
    Abstract: An oil-containing solid in which liquid oil is contained in a large amount and from which oil seepage is slight; and a process for producing the same. The oil-containing solid is produced by impregnating a porous solid with a W/O emulsion. Further, use is made of the W/O emulsion having a water-soluble gellable substance incorporated in the water phase thereof. Consequently, the water-soluble gellable substance is converted to a gel in pores of the porous solid, thereby enhancing the liquid oil leakage preventing effect of the W/O emulsion.
