Plastics for food contact can be rather difficult to trace, owing to the large variety of components and the various processes used to obtain the final product. Considering the finished product that comes in contact with food, a first classification can be made as follows ... 

So long as uncoated mild steel tanks are accepted, there is a danger of mechanical contamination by rust flakes or powder or of the formation of iron salts by interaction with fatty acids in acid oils. Accordingly, such tanks are often coated with inert materials (plastics for food contact). The dangers of metal contamination can be eliminated altogether by using stainless steel.

Acetyl triethyl citrate n. CH3COOC3H4 (C00C2H5)3. a plasticizer produced by esterifying and acetylating citric acid, used in cellulose nitrate, cellulose acetate, and certain vinyls, e.g., polyvinyl acetate. It has been FDA-approved for food-contact use. Wypych G (ed) (2003) Plasticizer s data base. Noyes Publication, New York. 

Di(2-ethylhexyl) azelate n. (dioctyl azelate, DOZ) (CH2)7[C00CH2-CH(C2H5) QH9]2. a plasticizer for vinyl chloride polymers and copolymers. It is one of the most compatible of the low-temperature, monomeric plasticizers, has low volatility, and imparts low extractability by water and soapy water. This plasticizer has been approved for food-contact use. 

Glycerol triacetate -( )trI- a-so- tat (tria-cetin). A plasticizer for cellulosic resins, polymethyl methacrylate, and polyvinyl acetate. It has been approved by the FDA for food-contact use. 

Di-n-hexyl Azelate n (DNHZ) (CH2)7(COOC6Hi3)2. A plasticizer for cellulose and vinyl resins. It has been approved for food-contact use, has low volatility and good compatibility. 

Epoxy Plasticizer n (epoxides plasticizer) Any of a large family of plasticizers obtained by the epoxidation of vegetable oils or fatty acids. The two main types are (a) epoxidized unsaturated triglycerides, e.g., soybean oil and linseed oil and (b) epoxidized esters of unsaturated fatty acids e.g., oleic acid, or butyl-, octyl-, or decyl- esters. Most epoxy plasticizers have a heat-stabilizing effect and they are often used for stabilization in conjunction with other stabilizers. Epoxidized oils generally have good resistance to extrusion and migration and low volatility, but they cannot be used as sole plasticizers in unfilled vinyl compounds and hence are not considered to be primary plasticizers. Certain epoxidized soybean oils have been FDA-approved for food-contact use. 

This new collection of additives used in plastics for food contact [2] can be seen as a logical supplement to the earlier collection of monomers and other starting materials. That earlier collection was described in two handbooks entitled Spectra for the Identification of Additives in Food Packaging [3] and Spectra for the Identification of Monomers in Food Packaging [4]. These books presented information on monomeric substances listed in Directive 90/128/EEC and its amendments which restrict the range of monomers and other starting substances that can be used for the production of plastic materials and articles intended for food contact applications.
