(2) The finished food-contact article shall yield not more than milligram per square inch of acrylonitrile monomer when exposed to distilled water and 3 percent acetic acid at deg. F for 15 days when analyzed by a polarographic method titled "Extracted Acrylonitrile by Differential Pulse Polarography," which is incorporated by reference. In addition, two other carcinogens—vinyl chloride and acrylonitrile, both residual monomers—are allowed at very low levels (insert values and references) as a result of the plastics used in food-packaging materials. Such chemicals are considered by the agency to be “constituents” of the food-packaging material rather than by:
important materials for lightweight, high-strength applications in aeronautics, automotive, engineering, etc. Acrylonitrile is used as a co-monomer the production of acrylonitrile, butadiene, styrene (ABS) and styrene acrylonitrile (SAN) polymers, which accounts for an additional 31% of use. These polymers are used in a wide range of oil-. Acrylonitrile/styrene copolymer consisting of the copolymer produced by polymerization of parts by weight of acrylonitrile and parts by weigth of styrene; for use with food of Types, I, II, III, IV, V, VI (except bottles), VII, VIII, and IX identified in table 1 of (c) of this chapter under conditions B (not to exceed 93 deg.
Acrylonitrile is an organic compound with the formula CH 2 CHCN. It is a colorless volatile liquid, although commercial samples can be yellow due to impurities. In terms of its molecular structure, it consists of a vinyl group linked to a is an important monomer for the manufacture of useful plastics such as is reactive and toxic at low al formula: C₃H₃N. The discovery and commercialization of the Sohio acrylonitrile process were the result of the talent, imagination, teamwork and risk-taking by Sohio's employees. Sohio's discovery led to the production of plentiful and inexpensive acrylonitrile of high purity as a raw material and to dramatic growth in the thermoplastics, synthetic fiber and.

Survey of acrylonitrile and methacrylonitrile levels in food contact materials and in foods: the sixth report of the Steering Group on Food Surveillance, the Working Party on Acrylonitrile and Methacrylonitrile.
The U.S. Food and Drug Administration (FDA) specified maximum residual acrylonitrile levels in food contact materials made from ABS (11 μg/g) and AS (50 or 80 μg/g according to the degree of polymerization) in the Code of Federal Regulations (U.S.
Food and Drug Administration,).Cited by: 6. Survey of acrylonitrile and methacrylonitrile levels in food contact materials and in foods. Food Surveillance Paper No. 6, HMSO, London. PAGE, D. & O'GRADY, R. Gas-solid chromatographic confirmation of vinyl chloride levels in oils and vinegars by using electrolytic conductivity by: Two different methods for acrylonitrile concentration assessment in food contact materials were compared.
The first and older method uses gas chromatography with nitrogen-phosphorous detection, whereas the second and more recent one studies acrylonitrile migration into food simulants - distilled water, 3% acetic acid, 10% ethanol, and 95% ethanol, and uses liquid chromatography with.
Results: The migration of acrylonitrile in AS plastic food contact materials was higher than that of ABS plastic food contact materials. Under the same condition, the acrylonitrile migration in Author: Chen Ming, Shu Yi, Mao Chen, Luo ShiPeng. With regard to unfavourable effects of acrylonitrile on man’s health it is necessary to know the content of free acrylonitrile in plastics (5) that are used in preparation of foodstuffs (food processors, juicers, pans of scales, food dishes etc.).

Survey of acrylonitrile and methacrylonitrile levels in food contact materials and in foods (Food Surveillance Papers: 6). The ratings below indicate the relative level of concern posed by exposure to the ingredients in this product - not the product itself - compared to other product formulations.
The ratings reflect potential health hazards but do not account for the level of exposure or individual susceptibility, factors which determine actual health risks, if any.
A quantitative analysis method for acrylonitrile and α-methacrylonitrile (2-methylpropenenitrile) was also developed, and the level of these compounds in 15 different cigarette brands was.
A government survey of the acrylonitrile content in food suggested that the average daily intake of acrylonitrile in the United Kingdom was likely to be less than μg/person (1).
On the basis of the reported acrylonitrile content of beverages in Sweden (1), a litre bottle would give an intake of l-3 μg. Other routes of exposure Free. Acrylonitrile is a colorless, liquid, man-made chemical with a sharp, onion or garlic-like odor.
Acrylonitrile is used mostly to make plastics, acrylic fibers, and synthetic rubber. Because acrylonitrile evaporates quickly, it is most likely to be found in the air around chemical plants where it is made.
Acrylonitrile breaks down quickly in the air. Methacrylonitrile, stabilized appears as a clear colorless liquid. Less dense than water. Boiling point °F. Very be toxic by ingestion, inhalation and skin absorption. Used to make plastics and coatings.

Saunders Company, pp. mmol/kg) radioactive dose of acrylonitrile (2-[14C]VCN, mg/ kg) or methacrylonitrile (2-[MC]MeVCN, mg/kg), the tissue distribution, covalent interaction, and elimination were compared (at 5 min to 48 hr) in male Fischer rats using whole-body autoradiography (WBA).
Autoradiographs obtained from freeze. The level of acrylonitrile monomer determined is expressed as milligrammes of acrylonitrile per kilogram of food or food simulant.
The method is appropriate for the quantitative determination of acrylonitrile monomer at minimum levels of down to 0,01 mg/kg to 0, mg/kg, or lower, in food simulant, depending on the applied test conditions (see.
This substance can be found in products with material based on: fabrics, textiles and apparel (e.g. clothing, mattress, curtains or carpets, textile toys), plastic (e.g.
food packaging and storage, toys, mobile phones) and rubber (e.g. tyres, shoes, toys). Widespread uses by professional workers. The European Food Safety Authority (EFSA) has adopted a new opinion on the occurrence and risks associated with the chemical substance semicarbazide (SEM) in food.
This follows earlier advice issued in The occurrence of SEM in foods, including baby foods, packaged in glass jars and bottles, was first discovered by industry and its origins were traced to the breakdown of.
