Absorbent article with fluid treatment agent
View Patent ↗A personal care absorbent article, such as a sanitary pad or napkin, wound dressing, and the like having one or more layers of absorbent material treated with a red blood cell lysing agent and a gelling agent. The effect of combining a lysing agent that thins menses or other blood-containing bodily fluids with a gelling agent that thickens menses or other blood-containing bodily fluids is enhanced agglomeration and increased viscosity of the blood-containing bodily fluids that come in contact with the treated material.
1. An absorbent material component comprising:
a layer of absorbent material;
a red blood cell lysing agent applied to a central region of the layer; and
a gelling agent applied to a perpheral region of the layer;
wherein the red blood coil lysing agent and the gelling agent are applied separately and not integrated together into the absorbent material component.
2. The absorbent material of claim 1 wherein the layer of absorbent material comprises a material selected from the group consisting of airlaid, airformed, wetlaid, absorbent laminates, nonwovens, fluid permeable polymeric film, and combinations thereof.
3. The absorbent material of claim 2 , wherein the layer of absorbent material further comprises a superabsorbent material.
4. The absorbent material of claim 1 , wherein the gelling agent is selected from the group consisting of chitosan salts, polyquaternium cellulosic polymer, and cellulose with propylene oxide groups.
5. The absorbent material of claim 1 wherein the red blood cell lysing agent is selected from the group consisting of an octylpolyglycoside, an alkoxylated polysiloxane, an alkoxylated alcohol, an alkyl substituted amino acid, an alkyl sulfate, a aulfosuccinate, a sarcosinate, saponin, and combinations thereof.
6. The absorbent material of claim 1 , wherein the gelling agent is present in a concentration of between about 1% and about 15% by weight of the material.
7. The absorbent material of claim 1 , wherein the gelling agent is present in a concentration of between about 2% and about 10% by weight of the material.
8. The absorbent material of claim 1 , wherein the gelling agent is present in a concentration of between about 3% and about 8% by weight of the material.
9. The absorbent material of claim 1 , wherein the red blood cell lysing agent is present in a concentration of between about 2% and about 40% by weight of the material.
10. The absorbent material of claim 1 , wherein the red bleed cell lysing agent is present in a concentration of between about 6% amid about 35% by weight of the material.
11. The absorbent material of claim 1 , wherein the red blood cell lysing agent is present in a concentration of between about 8% and about 30% by weight of the material.
12. An absorbent laminate comprising,
a central region of a first layer of absorbent material treated with a red blood cell lysing agent; and
a peripheral region of a second layer of absorbent material treated with a gelling agent, wherein the central region of the first layer is not treated with the gelling agent and the peripheral region of the second layer is not treated with the red blood cell lysing agent.
13. The absorbent laminate of claim 12 , wherein the first layer comprises a liner and the second layer comprises a containment layer.
14. The absorbent laminate of claim 12 , wherein the first layer comprises an intake layer adjacent a liner, and the second layer comprises a containment layer adjacent the intake layer.
15. The absorbent laminate of claim 12 , wherein the first layer comprises a material selected from the group consisting of airlaid, airformed, wetlaid, absorbent laminates, nonwovens, fluid permeable polymeric film, and combinations thereof.
16. The absorbent laminate of claim 12 , wherein the second layer comprises a material selected from the group a insisting of airlaid, airformed, wetlaid, absorbent laminates, nonwovens and combinations thereof.
17. The absorbent laminate of claim 16 , wherein the second layer further comprises a superabsorbent material.
18. The absorbent laminate of claim 12 , wherein the gelling agent is selected from the group consisting of chitosan salts, polyquaternium cellulosic polymer, and cellulose with propylene oxide groups.
19. The absorbent laminate of claim 12 , wherein the red blood cell lysing agent is selected from the group consisting of an octylpolyglycoside, an alkoxylated polysiloxane, an alkoxylated alcohol, an alkyl-substituted amino acid, an alkyl sulfate, a sulfosuccinate, a sarcosinate, saponin, and combinations thereof.
20. The absorbent laminate of claim 12 , wherein the gelling agent is present in a concentration of between about 1% and about 15% by weight of the laminate.
21. The absorbent laminate of claim 12 , wherein the gelling agent is present in a concentration of between about 2% and about 10% by weight of the laminate.
22. The absorbent laminate of claim 12 , wherein the gelling agent is present in a concentration of between about 3% and about 8% by weight of the laminate.
23. The absorbent laminate of claim 12 , wherein the red blood cell lysing agent is present in a concentration of between about 2% and about 40% by weight of the laminate.
24. The absorbent laminate of claim 12 , wherein the red blood cell lysing agent is present in a concentration of between about 6% and about 35% by weight of the laminate.
25. The absorbent laminate of claim 12 , wherein the red blood cell lysing agent is present in a concentration of between about 8% and about 30% by weight of the laminate.
