Stoma treatment

Claim 1

A method of relieving irritation of skin surrounding an iliac stoma; comprising the application to the skin, of a paste comprising an effective of at least 40 percent by weight of calcium, sodium poly(vinyl methyl ether-maleate) in a petroleum jelly base.

Claim 2

A method of relieving irritation of skin surrounding an iliac stoma; comprising the application to the skin, of a paste comprising an effective of at least 40 percent by weight of calcium, sodium poly(vinyl methyl ether-maleate) in a petroleum jelly base.

Claim 3

A method of relieving irritation of skin surrounding an iliac stoma comprising the application to the skin, of a paste having as a stabilizing component a material comprising an effective amount of at least 40 percent by weight of said paste and being a water-insoluble water-sensitized polymeric material; said material characterized by a particle size of minus 150-mesh U.S.B.S. sieve, by an apparent bulk density greater than 0.5 gram per cubic centimeter, and by a pH between 5 and 8.5, the pH being determined on a one percent by weight aqueous dispersion of said material in water; said material consisting essentially of a partial mixed salt of a copolymer selected from the group consisting of copolymers and partial lower alkyl esters of these copolymers, said copolymers consisting essentially of the repeated structural unit, ##STR1## wherein X and Y separately each represent a hydroxyl radical and X and Y together represent a bivalent oxygen atom, R represents an alkyl radical of less than 5 carbon atoms, n is an integer greater than one representing the number of repeated occurences of said structural unit in a molecule of said copolymer and n is large enough to characterize said polymer as having a specific viscosity larger than 1.2, the specific viscosity being determined in methyl ethyl ketone at 25° C, said partial lower alkyl esters of said copolymer having less than one-third of the total initial carboxyl groups esterified, said partial mixed salts containing calcium cations and alkali cations, in a mole ratio of between 1:1 and 5:1, the alkali cations selected from the group consisting of sodium, potassium, and quaternary ammonium cations, with not more than one-third of the total initial carboxyl groups unreacted.

Claim 4

A method of relieving irritation of skin surrounding an iliac stoma comprising the application to the skin, of a paste having as a stabilizing component a material comprising an effective amount of at least 40 percent by weight of said paste and being a water-insoluble water-sensitized polymeric material; said material characterized by a particle size of minus 150-mesh U.S.B.S. sieve, by an apparent bulk density greater than 0.5 gram per cubic centimeter, and by a pH between 5 and 8.5, the pH being determined on a one percent by weight aqueous dispersion of said material in water; said material consisting essentially of a partial mixed salt of a copolymer selected from the group consisting of copolymers and partial lower alkyl esters of these copolymers, said copolymers consisting essentially of the repeated structural unit, ##STR1## wherein X and Y separately each represent a hydroxyl radical and X and Y together represent a bivalent oxygen atom, R represents an alkyl radical of less than 5 carbon atoms, n is an integer greater than one representing the number of repeated occurences of said structural unit in a molecule of said copolymer and n is large enough to characterize said polymer as having a specific viscosity larger than 1.2, the specific viscosity being determined in methyl ethyl ketone at 25° C, said partial lower alkyl esters of said copolymer having less than one-third of the total initial carboxyl groups esterified, said partial mixed salts containing calcium cations and alkali cations, in a mole ratio of between 1:1 and 5:1, the alkali cations selected from the group consisting of sodium, potassium, and quaternary ammonium cations, with not more than one-third of the total initial carboxyl groups unreacted.
