An odor controlling material and an absorbent article containing material for removing or reducing odor emanating from certain gaseous and liquid compounds in body fluid. The odor controlling material includes conventional absorbent materials such as silica, alumina, silicates, and natural and synthetic aluminosilicates that are doped with one or more dopants, which have the same or similar chemical characteristics as the gaseous or liquid compounds in the body fluid to be absorbed. These dopants include fatty acids and their derivatives, amines and their salts, ammonia, alcohols, aldehydes, ketones, heterocompounds containing at least one nitrogen, sulfur or oxygen atom and mixtures thereof. The odor control material is suitable for incorporation in an absorbent article such as a pantiliner or a sanitary napkin.

1. An odor controlling material comprising, an adsorbent material, said adsorbent material being selected from the group consisting of silica, alumina, silicates, natural and synthetic aluminosilicates and mixtures thereof, said adsorbent material being doped with one or more dopants selected from the group consisting of fatty acids and their derivatives, ammonia and salts thereof, amines and salts thereof, alcohols, aldehydes, ketones, heterocompounds selected from the group consisting of heterocyclic compounds containing one or two heteroatoms selected from nitrogen, sulfur, and oxygen, mercapto-compounds, thio-compounds, and other compounds containing at least one sulfur atom per molecule and having a boiling point of up to 170° C. at atmospheric pressure, and mixtures thereof; wherein said dopant is present at from 1 to 1000 parts dopant per million parts of said adsorbent material.2. An odour controlling material according to claim 1, wherein the adsorbent material is active silica.3. An odor controlling material according to claim 2, wherein the fatty acids and their derivatives are selected from the group consisting of straight and branched chain fatty acids containing from 1 to 12 carbon atoms, and alkali and alkaline earth metal salts and their esters, ammonium salts, and amides thereof, and mixtures thereof.4. An odour controlling material according to claim 1 which has a pH of 7±0.5.5. An odour controlling material according to claim 1 which comprises at least one dopant which has more than one active group.6. A blend of odour control materials comprising two or more odour control materials according to claim 1.7. An absorbent article comprising at least one adsorbent material, said material selected from the group consisting of silica, alumina, silicates, natural and synthetic aluminosilicates and mixtures thereof, said material being doped with one or more dopants selected from the group consisting of fatty acids and their derivatives, amines and their salts, ammonia and salts thereof, alcohols, aldehydes, ketones, heterocompounds selected from the group consisting of heterocyclic compounds containing one or two heteroatoms selected from nitrogen, sulfur, and oxygen, mercapto-compounds, thio-compounds, and other compounds containing at least one sulfur atom per molecule and having a boiling point of up to 170° C. at atmospheric pressure; wherein said dopant is present at from 1 to 1000 parts dopant per million parts of said adsorbent material.8. An absorbent article according to claim 7, wherein the material is active silica.9. An absorbent article according to claim 8, wherein the fatty acids and their derivatives are selected from straight and branched chain fatty acids containing from 1 to 12 carbon atoms, and alkali and alkaline earth metal salts and their esters, ammonium salts, and amides thereof, and mixtures thereof.10. An absorbent article according to claim 8, wherein the amines and their salts are selected from amines having a boiling point of up to 170° C. at atmospheric pressure.11. An absorbent article according to claim 7 which has a pH of 7±0.5.12. An absorbent article to claim 7 comprising at least one dopant, the dopant having more than one active group.13. An absorbent article according to claim 7 comprising two or more of said materials.14. An absorbent article according to claim 7 which is a pantiliner or a sanitary napkin.
