UNIPLEX 84
ACETYL TRIBUTYL CITRATE
CAS. NO 77-90-7
UNIPLEX 84 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:
172.515 (Synthetic flavoring substance adjuncts)
175.105 (Adhesives)
175.300 (Resinous and polymeric coatings)
175.320 (Resinous and polymeric coatings for polyolefin films)
175.380 (Xylene formaldehyde resins condensed with 4, 4'
isopropylidenediphenyl-epichlorohydrin epoxy resins)
UNIPLEX 84 is used as the milling lubricant for aluminum foil or sheet steel or for use in cans for
beverage and food products.
UNIPLEX 84 has been widely formulated in polyvinyl chloride polymers for children's toys as a
safe alternative to other widely used plasticizers.
The low odor and excellent color stability of UNIPLEX 84 make it an excellent general purpose
plasticizer. Uniplex 84 is a good plasticizer for cellulose acetate films, replacing dibutyl
phthalate.
Other uses of UNIPLEX 84 include:
175.390 (Zinc-silicon dioxide matrix coatings)
176.170 (Components of paper and paperboard in contact with aqueous and fatty
foods)
176.180 (Components of paper and paperboard in contact with dry foods)
177.1200 (Cellophane)
177.1210 (Closure with sealing gaskets for food containers)
178.3910 (Surface lubricants used in the manufacturing of metallic articles)
181.27 (Specific Prior-Sanctioned Food Ingredients - Plasticizers)
1) Aerosol hair sprays
2) Dairy product cartons
3) Drink bottle caps
4) Food jar caps
5) Solution coatings for foil and paper
