INTERNATIONAL PROGRAMME ON CHEMICAL SAFETY WORLD HEALTH ORGANIZATION TOXICOLOGICAL EVALUATION OF CERTAIN FOOD ADDITIVES AND FOOD CONTAMINANTS WHO FOOD ADDITIVES SERIES 19 Rome, 19-28 March 1984 The International Programme on Chemical Safety (IPCS), established in 1980, is a joint venture of the United Nations Environment Programme (UNEP), the International Labour Organisation (ILO), and the World Health Organization (WHO). The overall objectives of the IPCS are to establish the scientific basis for assessment of the risk to human health and the environment from exposure to chemicals, through international peer-review processes, as a prerequisite for the assistance in strengthening national capacities for the sound management of chemicals. The Inter-Organization Programme for the Sound Management of Chemicals (IOMC) was established in 1995 by UNEP, ILO, the Food and Agriculture Organization of the United Nations, WHO, the United Nations Industrial Development Organization and the Organisation for Economic Co-operation and Development (Participating Organizations), following recommendations made by the 1992 UN Conference on Environment and Development to strengthen cooperation and increase coordination of the policies and activities pursued by the Participating Organizations, jointly or separately, to achieve the sound management of chemicals in relation to human health and the environment.

CONTAMINANTS Potential migrants from food-contact materials Acrylonitrile Provisional acceptance9 Bis(2-ethylhexyl) phthalate Provisional acceptance9 Styrene [0.0410] Vinyl chloride Provisional acceptance9 Notes 1 N, new specifications prepared; O, specifications not prepared; R, existing specifications revised; S, specifications exist, revision not considered or not required; the existing, new, or revised specifications are tentative and comments are invited. 2 The statement "ADI not specified" means that, on the basis of the available data (chemical, biochemical, toxicological, and other), the total daily intake of the substance, arising from its use at the levels necessary to achieve the desired effect and from its acceptable background in food, does not, in the opinion of the Committee, represent a hazard to health. For that reason, and for reasons stated in the individual evaluations, the establishment of an acceptable daily intake (ADI) is not deemed necessary. 3 Insufficient toxicological data available. 4 Temporary acceptance. 5 Group ADI for alpha-ionone and beta-ionone, singly or in combination. 6 Group ADI for octanal and nonanal, singly or in combination. 7 The previous recommendation that 2-nitropropane should not be used as a solvent in food processing changed to temporary acceptance for use as a fractionating solvent for edible fats and oils only, with the stipulation that residue levels are kept to the lowest technologically attainable, which is understood to be lower than the detection limit by current analytical methods. 8 Group ADI for saccharin, saccharin calcium, saccharin sodium, and saccharin potassium, singly or in combination. 9 The use of food-contact materials from which the substance may migrate is provisionally accepted, on condition that the amount of the substance migrating into the food is reduced to the lowest level technologically attainable. 10 This figure represents the provisional maximum tolerable daily intake (PMTDI) of styrene. It is not an ADI. The MTDI for styrene is provisionally accepted under the same conditions as those set out in Note 9. 11 The existing specifications for some salts of fatty acids are incorporated in the new specifications. 12 Replaces the specification for methyl violet, of which the colour crystal violet is a purified compound. 13 The existing specifications incorporated into a single specification covering a series of related substances. 14 No knowledge of the continuing use of the colour in food and no information received with regard to the specifications over a long period of time. 15 No ADI allocated because of insufficient data. 16 The colour is little used and it is understood its use will be discontinued. 17 Specifications withdrawn at previous meetings.
