Abstract
Abstract Protective sealing compositions in the form of molded rings or sheets, which comprise gelled mixtures of water-absorbing particulate hydrocolloid gum and non-toxic liquid polyhydroxy alcohol are provided with increased resistance to the drained fluid (viz. urine or intestinal fluids) by incorporating a small amount of colloidal silica. Fumed silica is preferred. By limiting the amount of silica added appreciable reductions in the wet tack and/or dry tack of the composition can be avoided. The compositions can be used with ostomy devices, wound drainage devices, and incontinence devices.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
69 words
A-protective sealing composition in molded form for application to the skin composed primarily of an admixture of a gellable water-absorbing particulate hydrocolloid gum and a non-toxic polyhydroxy alcohol characterized by also containing from 1 to 3% by weight of fumed silica together with from 5 to 20% by weight of polyacrylamide resin, said composition in molded form having been subjected to gamma irradiation sufficient to cross-link the polyacrylamide resin.
Claim 2
Dependent Claim
69 words
A-protective sealing composition in molded form for application to the skin composed primarily of an admixture of a gellable water-absorbing particulate hydrocolloid gum and a non-toxic polyhydroxy alcohol characterized by also containing from 1 to 3% by weight of fumed silica together with from 5 to 20% by weight of polyacrylamide resin, said composition in molded form having been subjected to gamma irradiation sufficient to cross-link the polyacrylamide resin.
Claim 3
Dependent Claim
33 words
The composition of claim 1 which is further chara- terized in that it contains from 50 to 70% by weight of polyhydroxy alcohol and from 15 to 25% by weight of hydrocolloid gum.
Claim 4
Dependent Claim
17 words
The composition of claim 1 or claim 2 further characterized in that said polyhydroxy alcohol is glycerin.
Claim 5
Dependent Claim
24 words
The composition of claims 1, 2, or 3 further characterized in that said hydrocolloid gum is a mixture of karaya and sodium carboxymethyl cellulose.
