phthalate-free plasticizers

When it comes to plastics for medical devices, softness, flexibility, and patient safety are the key attributes. Whether ensuring optimum patient comfort for the tubing that interacts with the body or providing safe storage and transportation of blood and its components, plasticizers play a crucial role.

Citroflex™ B-6 Phthalate-Free Plasticizer offers excellent performance in medical PVC plastics formulations. With a clean toxicological profile, Citroflex B-6 presents a proven, field-tested alternative to traditional DEHP plasticizers.

As an easy, drop-in replacement for DEHP, Citroflex B-6 assures PVC compounders of production continuity with minimal formulation or process adjustment. This empowers compounders to provide blood bag manufacturers with regulatory-compliant products having similar or improved performance.

Citroflex B-6 Plasticizer (n-Butyryl Tri-n-hexyl Citrate) is a citric acid ester specially formulated for use in PVC medical articles such as tubing and intravenous bags where the content medium is aqueous-based.

medical application examples include: extra-corporeal tubing, blood bags, IV solution containers & sets, catheters

features
  • a truly phthalate-free plasticizer
  • listed in the European Pharmacopeia
  • clean toxicological profile as documented in SCENIHR Report, Revision February 2016
  • excellent low-temperature flexibility
  • proven, field-tested solution for 20+ years

for use in medical tubing

B-6 enables the tubing to maintain flexibility and resistance to cracking at low temperatures. Unlike other phthalate-free alternatives, such as Di(2-Ethylhexyl)adipate (DEHA), Citroflex B-6 Plasticizer exhibits lower volatility and reduced potential for leaching.

for use in medical components

Citroflex B-6 Plasticizer has low extractability into lipid media, making it particularly useful for blood bags and related products. B-6 offers high molecular weight and low extractability, preventing plasticizer migration. It nearly duplicates the properties of diethylhexyl phthalate (DEHP).
