An absorbent core comprising a) fluff pulp fiber treated with polysiloxane; and, b) superabsorbent material; wherein the absorbent core has a superabsorbent content of about 25% or greater, has a density of about 0.25 g/cm3 or greater, and a Young's modulus of about 500 psi or less and wherein the polysiloxane has a general structure of: wherein: n is an integer ≧2; each R' and R" moiety comprises independently an organofunctional group and non-organofunctional group or mixtures thereof. 20. The absorbent core of claim 19, wherein the absorbent core has a first insult rate of about 0.7 mL/s or greater and a second insult rate of about 2 mL/s or greater. 21. The absorbent core of claim 19, wherein the absorbent core has a basis weight of about 50 g/m2 or greater. 22. The absorbent core of claim 19, wherein the polysiloxane comprises an amino-functional moiety. 23. The absorbent core of claim 19, wherein the amino-functional moiety is selected from the group of primary amine, secondary amine, tertiary amine, quaternary amine, unsubstituted amide, and mixtures thereof. 24. The absorbent core of claim 19, wherein the fluff pulp fibers are treated with the polysiloxane before the absorbent core is formed. 25. A disposable absorbent product containing the absorbent core of claim 19. 26. A disposable absorbent product containing the absorbent core of claim 20.
