Citroflex™ B-6 Plasticizer (n-Butyryl Tri-n-hexyl Citrate)

Citroflex B-6 is a specially formulated citric acid ester for use in PVC medical articles such as tubing and intravenous bags where the content medium is aqueous-based.  Citroflex B-6 has low extractability into lipid media, making it particularly useful for blood products.  It nearly duplicates the properties of di-(2-ethylhexyl) phthalate.
