International Classification:

A61F 1315

US Classification:

604378, 604367, 604385101

Abstract:

There is provided an absorbent system for personal care products which may be transversely divided into about an equally sized center zone, two intermediate zones and two end zones where the ratio of the amount of liquid stored in the center zone to the amount of liquid stored in at least one of the end zones 30 minutes each of three insults of 80 ml according to a MIST Evaluation Test after less than 5:1. Such an absorbent system may be used in personal care products like diapers, training pants, feminine hygiene products, absorbent underpants, adult incontinence products, and the like.

US Classification:

442149, 442414, 604365, 604368, 604372, 604387

Abstract:

An absorbent composite material composed of a fibrous absorbent material and a binding agent, the binding agent binding at least a portion of the fibers of the fibrous absorbent material. The fibrous absorbent material is preferably selected from the group consisting of fluff pulp, synthetic fibers, natural fibers, and combinations thereof. The material suitable for use as an absorbent in personal care absorbent articles such as diapers, training pants, and adult incontinence garments.

International Classification:

A61F 13/15

US Classification:

604367, 368364, 368365, 368370, 368374, 368375

Abstract:

Absorbent structures that form superabsorbent polymers in situ. The structures include an absorbent material and a fibrous material containing an activating agent. The fibrous material releases the activating agent upon stimulation with an activator, which causes the polymer to become a superabsorbent polymer. The absorbent component is desirably a water-swellable, water-insoluble polymer. The absorbent structures form a superabsorbent composition in situ. Methods of making the activating agent containing fibrous material are provided.

International Classification:

A61L 15/56
G01N 21/78

US Classification:

604361, 436 39

Abstract:

A personal absorbent article (e.g., feminine care pad, sanitary napkin, diaper, incontinence pad etc.) has a color change indicator that employs a synergistic combination an acid component and a basic component for signaling to a user when the absorbent article may foster bacterial growth due to moisture absorption. After a certain period of time, the user can visually inspect the color of the color change indicator to obtain an indication of when it is time to replace or remove the article.

International Classification:

A61F 1315

US Classification:

604378

Abstract:

A multifunctional material is provided for use in personal care products. The multifunctional material has a permeability between 100 and 10000 Darcys and a capillary tension between about 2 and 15 cm. Structures containing this multifunctional material can have a runoff rate of less than 25 ml per 100 ml insult, over its life. The multifunctional material should have between about 30 and 75 weight percent of a slow rate superabsorbent, between 25 and 70 weight percent of pulp and from a positive amount up to about 10 percent of a binder component. The material preferably has a density between about 0. 05 and 0. 5 g/cc. The material has a liquid pass through function which desorbs a surge material across time frames consistent with user conditions and releases the liquid for distribution to remote storage locations. The material, when combined with the intake and distribution materials, defines a composite structure for use in personal care products.
