The authors deal with the migration behaviour of bezophenone-based ultraviolet absorbents for commodities of low-pressure polyethylene, high-pressure polyethlene, polypropylene and polystyrene. These ultraviolet-absorbent-stabilized plastics (up to 0.5% of ultraviolet absorbent) show a very slight tendency of the light stabilizers towards migration into aqueous, acid or dilute alcoholic foods. Very high migration values are obtained for sunflower oil, Fettsimulans HB 307 or 50% ethanol. The amount of 2-hydroxy-4-octoxybenzophenone which migrates into fat-free foods is only a fraction of the maximum daily dose; a risk to the consumers' health might thus be excluded. In fat-containing foods, the maximum daily dose is also not reached, but the single migration value is higher than the limit value (100 p.p.m.) for total migration. Consequently, the above ultraviolet absorbents should not be used for the ultraviolet stabilization of plastics designed for packing these products. An evaluation of the safety of ultraviolet absorbents of the Dastib type will be possible only if sufficient toxicological data are available.
作者研究了二苯甲酮类紫外线吸收剂在低压聚乙烯、高压聚乙烯、聚丙烯和聚苯乙烯等商品中的迁移行为。这些添加了紫外线吸收剂（含量高达0.5%）的稳定化塑料，其光稳定剂向水性、酸性或稀酒精性食品中的迁移趋势非常轻微。对于葵花籽油、Fettsimulans HB 307或50%乙醇，迁移值非常高。迁移到无脂食品中的2-羟基-4-辛氧基二苯甲酮的量仅为最大日剂量的一小部分；因此可以排除对消费者健康的风险。在含脂食品中，虽然也未达到最大日剂量，但单次迁移值高于总迁移的限值（100 ppm）。因此，上述紫外线吸收剂不应用于包装这些产品的塑料的紫外线稳定化处理。只有在有足够的毒理学数据时，才有可能对Dastib型紫外线吸收剂的安全性进行评估。
