Watch out Dermabond! The FDA has given approval to Chesson Labs out of Durham, NC for company’s NUVADERM™ liquid bandage. The product, approved for marketing to healthcare professionals and directly to consumers, is either sprayed or brushed on to “to cover intact skin and minor cuts, scrapes, burns or irritations of the skin, to help keep them clean and dry and help protect them from infection.” The non-toxic material keeps moisture and dirt from penetrating the applied film layer while allowing oxygen to reach the wound site.
Some technical details of the NUVADERM:
NUVADERM is a single component, poly(urea-urethane) liquid emulsion polymer that is composed of large, highly complex molecules that incorporate a broad range and distribution of hard and soft segments. The different segments are tied together with urea and urethane linkages that are formed during synthesis. NUVADERM is applied topically to form a non-toxic, hydrophobic, elastomeric coating that provides a barrier against moisture but that is permeable to oxygen. NUVADERM requires no initiator or catalyst and therefore no mixing steps. It remains liquid until released into the air and therefore is applied by spraying or with an applicator brush.
