Abstract
Abstract @ Citrate-ester plasticized polyvinyl chloride containers for the storage of blood and blood components. Preferred plasticizers include tri-esters of citric acid (or acylated citric acid) and 4-10 carbon alcohols such as acetyl tri-butyl citrate, n-butryl tri-n-hexyl citrate and acetyl tri-n-octyl or decyl citrate. Blood bags and multiple blood bags made from such citrate plasticized PVC film materials have high 0 2 transmissibility, withstand breakage at low temperatures and extractables which degrade into biologically acceptable products.
