Disclosed are absorbent articles having a cyclodextrin complex of one or more odor controlling organic compounds wherein the cyclodextrin is a substituted cyclodextrin (wherein the H atom of OH groups in positions 2, 3 and 6 is partially or entirely replaced by a substituent -R) having a substitution degree (DS) of 0.4 or more -R substituents per molecule of cyclodextrin and wherein substitution in position 2 is 20% or above, in position 6 is 20% or above and in position 3 is 50% or below. Cyclodextrin complexes of this type release the odor controlling organic compound much faster and in more complete manner than non-substituted or differently substituted cyclodextrin complexes thus the odor control efficacy is improved.
