UNIPLEX 83
TRI-N-BUTYL CITRATE
CAS. NO 77-94-1
UNIPLEX 83 is a safe economical plasticizer approved by the U.S. Food and Drug Administration
(FDA) for use in both indirect and direct contact food applications according to Code Federal
Regulation 21:75.105 (Adhesives)
UNIPLEX 83 has been widely formulated/plasticize in polyvinyl chloride polymers and cellulosic
resins as an "environmentally friendly" replacement to the phthalate plasticizers.
The low odor and excellent color stability of UNIPLEX 83 make it an excellent general purpose
plasticizer. Cellulose nitrate films plasticized with UNIPLEX 83 have lower volatility loss,
better resistance to yellowing and better adhesion to metals than those plasticized with dibutyl
phthalate.
UNIPLEX 83 is very effective as a defoamer in protein solutions.
UNIPLEX 83 does not support fungal growth in resins.
Other uses of UNIPLEX 83 include:
Assay, minimum 99.0%
Acidity, (as Citric Acid) maximum 0.02%
Color, maximum 50 APHA
Water, (Karl Fischer), maximum 0.25%
Odor Essentially odorless
Specific Gravity, 25/25°C 1.037-1.045

4) Food jar caps
UNIPLEX 83 is economical both on a cost and a performance basis, while exhibiting excellent
compatibility with a wide range of polymers and resins. Resins plasticized with UNIPLEX 83
exhibit excellent heat stability and low toxicity.
