<p>Compositions are disclosed which are normally pressure sensitive adhesive at ambient temperature, which are also absorbent of fluids, especially body fluids, and which contain 0.1 to 65 wt.% of a cyclodextrin material. Such compositions have various uses in the medical field. Lower amounts of cyclodextrin, from 0.1 - 10 wt.%, can confer odour absorbing properties on the adhesive, useful in consumer and medical products. Small amounts of other active ingredients such as antimicrobial components, active drug ingredients, fragrances, etc. may advantageously be complexed within the cyclodextrin molecules. Such compositions are useful for example as antibacterial adhesives, or as adhesives that bleach the skin, prevent and diminish acne skin blemishes, or provide a cooling or warming sensation to the skin. Higher amounts of cyclodextrins, up to 65 wt.% of the composition, either alone or in combination with other absorbent fillers to total up to 65 wt.%, find utility especially as barrier adhesives for ostomy patients and as wound dressings, and are particularly useful in that they provide fluid absorbent adhesives that also possess odour absorbing properties. Such adhesives are particularly useful as ostomy adhesives.</p> |
