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

Citroflex™ Citric Acid Esters
Citroflex citric acid esters are suitable for use as phthalate-free alternatives to plasticizers such as low molecular weight adipates, phthalates, and sebacates in various polymer applications.
These esters are partially derived from bio-based raw materials and have been demonstrated to be biodegraded by microorganisms in soil.
They are ideal for use in bio-polymer systems and applications where high bio-sourced content or end-of-life biodegradability are desirable.
Citroflex esters are not volatile organic compounds (VOCs).
