Absorbent product having a liquid permeable surface and a liquid impermeable opposite surface, the absorbent product including an odor control material, the odor control material including a carrier material and a plurality of odor control particles adhered to the carrier material. The carrier material has a first surface located towards the liquid permeable surface of the absorbent product and a second opposite surface located towards the liquid impermeable surface of the absorbent product. The plurality of odor control particles are bonded to the second surface of the carrier material with a water soluble binder substance wherein the binder substance at least partly dissolves when in contact with an aqueous solution.

1. Absorbent product having a liquid permeable surface and a liquid impermeable opposite surface, wherein the absorbent product comprises an odor control material comprising a carrier material and a plurality of odor control particles adhered to the carrier material, the absorbent product comprising a liquid permeable topsheet, a liquid impermeable backsheet and an absorbent core enclosed between the topsheet and backsheet, wherein: the odor control material is located between the topsheet and the absorbent core;the carrier material has a first surface located towards the liquid permeable surface of the absorbent product and a second opposite surface located towards the absorbent core,the plurality of odor control particles consists of activated carbon and is bonded to the second opposite surface of the carrier material with a water soluble binder substance wherein the binder substance at least partly dissolves when in contact with an aqueous solution, andthe plurality of odor control particles is only on the second opposite surface of the carrier material. 2. Absorbent product according to claim 1, wherein the water-soluble binder substance has a molecular weight of 40 kDa or lower. 3. Absorbent product according to claim 2, wherein the water-soluble binder substance comprises a hydrophilic polymer. 4. Absorbent product according to claim 2, wherein the water-soluble binder substance comprises a hydrophilic low molecular weight compound. 5. Absorbent product according to claim 1, wherein the first surface of the carrier material is treated with surfactant(s). 6. Absorbent product according to claim 1, wherein the water-soluble binder substance comprises an additive selected from the group of plasticizer, stabilizer, agent improving dispersibility, pH regulating agent, antimicrobial substance, surfactant(s), and a mixture thereof. 7. Absorbent product according to claim 1, wherein the weight ratio binder substance to odor control particles is from 1:10 to 10:1. 8. Absorbent product according to claim 1, wherein the carrier material is a nonwoven material. 9. Absorbent product according to claim 1, wherein the carrier material is a foam material. 10. Absorbent product according to claim 1, wherein the odor control material covers 5-100% of the total surface area in a horizontal plane of the absorbent product. 11. Absorbent product according to claim 1, wherein the odor control material covers 5-60% of the total surface area in a horizontal plane of the absorbent product. 12. Absorbent product according to claim 1, wherein the carrier material is perforated or slitted for providing openings. 13. Absorbent product according to claim 3, wherein the hydrophilic polymer is a polyvinylpyrrolidone, polyethyleneoxide polyacrylic, starch or derivative of starch. 14. Absorbent product according to claim 4, wherein the hydrophilic low molecular weight compound is a monosaccharide, disaccharide, sugar alcohol, or polyol.
