Colorant has become an important hidden danger of safety and health of plastic products

Plastic coloring is an important part of plastic processing technology Colorful and beautiful plastic products not only enrich the market, but also beautify people's lives However, the use of unqualified plastic colorants or improper use of colorants may cause hidden dangers to consumers' health and safety The quality problems caused by the use of colorants have become one of the important reasons for the unqualified safety and health indicators of plastic products At present, European, American, Japanese and other countries and regions have formulated corresponding regulations on the types and requirements of colorants that can be used in food contact products For example, EU AP (89) 1 resolution has clear index requirements on the quality of plastic colorants, and FDA regulation 21cfr 178.3297 also has clear regulations on the allowable colorants and their maximum dosage in plastic products The colorant with inconsistent quality specification may bring many safety and health risks, mainly including the carcinogen aromatic amine exceeding the standard, the finished product bleaching test failing and the heavy metal content exceeding the standard, etc In addition, unqualified colorants may also contain harmful substances such as polychlorinated biphenyls The inspection and quarantine department found in the daily supervision that excessive addition of colorant is also one of the important reasons for unqualified plastic products For example, in order to meet the needs of customers, some enterprises add too much titanium dioxide and other substances in the production process of white products, resulting in the total migration of products in the detection of acid food or excessive evaporation residue Some enterprises add too much organic color powder or color masterbatch to PP products exported to the United States, which results in the unqualified detection of xylene extract, etc in addition, the excessive addition of some organic or inorganic colorants may also cause the unqualified decolorization test, the degradation of product folding resistance or appearance performance, etc and lead to the rejection of customers, etc In addition, some enterprises may use some brighteners, brighteners and other substances in addition to the conventional colorants in production, but the enterprises do not pay attention to the specific ingredients and other information, which also brings certain hidden dangers to the safety and health of plastic products, which need to be paid attention to In order to ensure the quality of export commodities and the health of consumers, the inspection and quarantine department suggests that the production enterprises should pay attention to the relevant information such as the composition, grade and qualification certificate of raw and auxiliary materials in the purchase of raw materials, so as to reduce the risk of unqualified products from the source In addition, the enterprise can consult with the inspection and quarantine department to confirm whether the raw and auxiliary materials such as color fixative and whitening agent are applicable to the relevant products Local governments and relevant departments should also strengthen the supervision of market circulation channels, prevent unqualified plastic products from entering the consumer goods market through strengthening market spot check and other means, and effectively protect the health rights and interests of consumers
