Black heart paper must be strictly guarded

Recently, the statement that "toilet paper can be carcinogenic when used as a napkin" and "a large amount of fluorescent whitening agent in toilet paper can cause cancer" has caused heated discussion on the Internet. So what is the difference between toilet paper and napkin? Is the fluorescent whitening agent carcinogenic? Is it true that the international food packaging association executive vice president and secretary general Dong Jinshi said that toilet paper and napkins should not be mixed.

According to the relevant national standards, toilet paper refers to “toilet paper”, while napkins are part of tissue paper, which includes facial tissue, napkin and paper handkerchief.

“Sanitary paper and tissue paper perform different hygiene standards. For example, microbiological standards, the former has a total bacterial colony of less than 600 per gram of paper, while the latter does not exceed 200. The combination of the two is not conducive to human health.” Dong Jinshi said .

Previously, Jiang Manxia, ​​secretary general of the Paper Committee of the China Paper Association, said that the Ministry of Health's "Disinfection Management Measures" promulgated in 2002 clearly stipulated that the use of toilet paper instead of napkins was prohibited. “Toilet paper allows the use of recycled waste paper (recycled pulp) for production, provided that the waste paper is clean and the used tissue paper must not be included; and the tissue paper is clearly stipulated to use the raw pulp, ie the waste cannot be used. Paper production."

For the statement that “fluorescent whitening agent can cause cancer”, Shen Yongjia, a professor at East China University of Science and Technology, said: “Fluorescent whitening agents are widely used in the paper industry, although the state regulations do not allow the inclusion of migratory fluorescent whitening agents in tissue paper. 'But, for its part, I don't think it will cause harm to the human body."

"The fluorescent whitening agent in toilet paper mainly has two sources: one is the recycled paper itself, and the other is added by the manufacturer after bleaching. However, the large amount of added is unscientific. Because the fluorescent whitening agent has yellowing Point, its content is generally less than 1 / 1000 (based on the weight of the paper), beyond this amount of paper will not turn white but will be yellow." Shen Yongjia said.

In fact, in most countries, the use of fluorescent whitening agents is not explicitly prohibited in the production of tissue paper. In China, in order to avoid consumer concerns, there is no requirement for the addition of fluorescent whitening agents in tissue paper.

“As for bleaching and perfumery, bleaching is a papermaking process. Although bleaching is very corrosive and oxidizing, it does not remain in the pulp after treatment; the flavor depends on the body of the paper, if it is not sensitive skin or It is a spice allergy, there is no problem." Shen Yongjia believes that the addition of bleach and flavor will not endanger human health.

"But the above premise is the qualified paper produced by regular manufacturers, like some inferior products produced by black-hearted manufacturers. The source of raw materials is very mixed, and may contain bacteria or harmful substances by itself." Shen Yongjia said.

"For example, when we went to an unannounced visit, we found that some illegal manufacturers dumped waste paper, and some even had moldy and stinking. Some of these papers are discarded papers for life, such as sanitary napkins and disposable diapers. There are also some scraps of chemical paper. The products produced from these papers contain various fungi, E. coli, or residues of chemicals and pesticides, which are extremely harmful to the human body.” Dong Jinshi said with great certainty.
