The invention relates to compositions that prevent expansion of a fire, suppress existing fire, as well as methods of preparing and using such compositions. The composition is comprised of water, pseudo-plastic high yield suspending agent and starch. Compositions may contain additional functional agents, such as rheological, wetting, foaming, coloring, chelating, antimicrobial and stabilizing agents. In the description of the present invention, all composition modifications are referred to as compositions. The composition, an augmentation of water, exhibits the characteristics of a sag resistant aqueous gel in the tank, but has shear thinning capacity, allowing the composition to be pumped or sprayed as easily as water. At the point of impact, when the sprayed composition is again at rest, it instantly reverts to a sag resistant aqueous gel. The composition also forms an intumescent, surface char layer upon contacting a fire. Foaming of the augmented composition on impact can be incorporated, which is advantageous for fighting petroleum fires.

A disposable diaper improved so that the wearer's skin can be reliably protected from being soiled with feces. A chassis constituting the diaper includes a spacer sheet attached to an inner sheet of the chassis. The spacer sheet has a front end zone and a rear end zone fixed to the inner sheet and an intermediate zone left free from the inner sheet. The intermediate zone is formed with an opening shaped so as to describe a circular arc which is convex forward. Along the opposite side edges of the opening, the spacer sheet is provided with elastic members extending in the length direction of the diaper and attached thereto in a stretched state in the direction. These elastic members extend forward with respect to the diaper along the peripheral edge of the opening so as to get close to a center line bisecting a width of the diaper.

A barrier against soiling to the wearer, this functional, easy to use bib comprises a body made of washable, flexible, durable and non-porous material with a front and a back. The body includes two semi-circular upper sections that protect the wearer's shoulders from soiling while also securing said bib around the wearer's neck. In fastening these upper sections together, a portion of the bib body arcs outwardly to conform to the wearer's upper body. The lower body of the bib forms into a bowed pocket for catching and retaining food particles and liquid thus shielding the user from soiling. The pocket is formed firstly by folding the lowest portion of the body upwards toward the front of the bib and fastening with corresponding snaps on each side and secondly, by folding the bottom right and left corners of the pocket around to the backside of the bib and fastening to the corresponding snaps on the backside. The pocket unfastens for the purpose of wiping and / or washing once removed from the wearer. The integrity of this pocket to retain liquid and food particles is assured and maintained by the special manner in which it is constructed, folded and fastened; by eliminating any folds within the pocket itself; by eliminating any perforations caused by affixing within said pocket, and by avoiding the use of applied trim along its edges. The resulting bib with an improved pocket prevents soiling to the wearer by catching and retaining a measurable amount of food and liquid debris without leaking and is easy to clean due to the ability to unfasten the pocket.
