<p>Oxidised cyclodextrins containing an average of at least 0.5 carboxyl group and/or at least 0.5 functional group selected from aldehyde groups and aldehyde-derived groups per molecule can be used as complexing agents, in particular in odour control for hygiene products. A fragrance component can be incorporated in the oxidised cyclodextrin and released when in use, and, in addition or alternatively, the oxidised cyclodextrin can absorb undesired odour components during use.</p> |
