    Abstract: An absorbent material with substantially improved liquid permeability such that it is not subject to gel blocking while maintaining a preferred absorbent capacity is disclosed. The absorbent material is in particulate form and is the reaction product of a water-insoluble, absorbent, hydrogel-forming polymer and a polycationic polymer, the reaction forming a covalent bond between the polymers. After the reaction, the absorbent material has a Saline Flow Conductivity greater than (500-11.5.multidot.GV)(10.sup.-7) cm.sup.3 sec/g where GV is the gel volume of the absorbent material.

  • Patent number: 6010734
    Abstract: Low calorie frozen desserts, in particular ice cream-like products, having a smooth, creamy, nongritty mouthfeel are can be produced. These frozen desserts contain fat that contains from about 30 to 100% of certain edible, wholly or partially nondigestible intermediate melting polyol polyesters, milk solids other than fat, sweetener, oil-in-water emulsifier, a flavoring substance, and water. The fat is substantially homogeneously dispersed in the aqueous phase as emulsified fat particles having an average particle size of about 5 microns or less. These frozen desserts are obtained by a process which initially involves the formation of a preemulsion by homogenizing a mixture which consists essentially of these intermediate melting polyol polyesters and only a portion of the other dessert ingredients. This preemulsion is then combined with the remaining dessert ingredients, homogenized, pasteurized, and at least partially frozen to provide the frozen desserts.

  • Patent number: 6007856
    Abstract: Oil-in-water dispersions of .beta.-carotene and other carotenoids that are stable against oxidation, even in the presence of polyphosphates, especially sodium hexametaphosphate. These oil-in-water dispersions are typically prepared by contacting a water-dispersible beadlet comprising at least about 5% colloidal carotenoid with the water phase to form droplets of the carotenoid that are in intimate contact with sufficient oil phase such that the carotenoid is stable against oxidation, even in the absence of an effective antioxidant such as ascorbic acid. The oil-in-water carotenoid dispersions of the present invention are especially useful in dilute juice beverages for providing vitamin A fortification and color, as well as other oil/water food and beverage products where vitamin A fortification and/or color are desired.

  • Patent number: 6004893
    Abstract: A shaped sanitary napkin. The sanitary napkin of this invention has an absorbent means, such as an absorbent core, and two flaps extending outwardly from the absorbent means. Each flap is associated with the absorbent means along a nonlinear line of juncture and each has two axes of flexibility. In use, the absorbent means is secured in the crotch of a panty and the flaps are secured about the elastic edges of the panty so that, when the panty is worn, the absorbent means is held adjacent the body while the flaps form a wall at each side of the absorbent means and seals against the body. Both the walls and the seals serve to prevent soiling of the body and clothing by menstrual fluid.

  • Patent number: 6001381
    Abstract: Wet-like cleaning wipes and similar articles that are particularly useful in removing perianal soils. These wipes comprise a carrier comprising at least one polarpliobic region, an optional, preferred substrate such as tissue paper web, and an emulsion applied to the carrier. The emulsion comprises a continuous external lipid phase and a dispersed internal polar phase. The continuous lipid phase of the emulsion is sufficiently brittle that it ruptures when subjected to low shear pressures during use to release the dispersed internal phase. Inclusion of the polarphobic region allows the ability to control flow of the internal water phase components following rupture of the emulsion.
