A highly impermeable encapsulating coating is disclosed prepared from a hydrolyzed ethylene-vinyl ester copolymer prepared by alcoholysis of, for example, ethylene-vinyl acetate using 4 to 9 times the amount of alcohol stoichiometrically required for a predetermined degree of hydrolysis.

Hydrolyzed ethylene vinyl acetate encapsulating coating

A tobacco-substitute smoking material is provided which, in the preferred embodiment includes a polysaccharide, such as cellulose or a derivative thereof, as a combustible organic ingredient. A tobacco alkaloidal material, such as nicotine or a derivative thereof, is incorporated into the smoking material in the form of a plurality of combustible microcapsules containing the tobacco alkaloidal material.

Tobacco-substitute smoking material

Microcapsules having a capsule core material surrounded by a relatively impermeable, densified protective wall and a method of producing such microcapsules are disclosed. To produce the microcapsules, an agitated system is provided including a liquid vehicle as a major component of the system and constituting a continuous first phase of the system. A plurality of discrete capsule core material entities are dispersed in the liquid vehicle and constitute a discontinuous second phase. A film-forming, cross-linkable, polymeric base material is also present in the liquid vehicle and, upon induction of phase separation within the agitated system, forms a sheath about the capsule core material entities. The formed sheath also contains entrapped liquid vehicle; however, a major portion of the entrapped liquid vehicle is subsequently extracted from the sheath, and the resulting densified polymeric base material in the sheath is then cross-linked to form a densified protective wall around the capsule core material.

Method of producing microcapsules and resulting product

A process of manufacturing substantially-homogeneous, stable microglobule of hydrophilic polymeric material, having oil-insoluble payload material dispersed therein; the microglobule; and methods of using the microglobules particularly in mariculture as balanced-diet nutrient materials.
