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 fumed silica or colloidal silica gel. By controlling 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, wound drainage and incontinence devices.
