fluorescent agents lack of fear

 Recently , on the " toilet paper when the paper napkin with carcinogenic ", " toilet paper contains large amounts of fluorescent whitening agent is carcinogenic ," saying aroused heated debate on the Internet . So toilet paper and napkins in the end what is the difference ? FWA carcinogenic and whether credible argument ? International plastic flame retardant  Food Packaging Association Executive Vice President and Secretary General Dong Lion said , toilet paper and napkins best not to mix .
According to the relevant national standards, especially toilet paper "toilet paper " and napkin handkerchief belonging to a part of handkerchief including facial tissue , napkins and paper handkerchiefs categories.
" Toilet paper and hygiene standards handkerchief perform different , for example, microbiological criteria , the former is the total number of bacterial colonies per gram paper is less than 600 , while the latter is not more than 200 , the two do not mix benefit human health. Allow the use of toilet paper recycled paper ( recycled pulp ) to produce, but the premise is that these are clean waste paper , used tissue paper must not include them ; while the handkerchief is clear that you want to use virgin pulp , paper production that can not be used . "
" FWA widely used paper , although state regulations in the handkerchief ' mobility is not allowed contain optical titanium dioxide anatase  brighteners ', but on its own terms , I think the human body and do not result in harm ."
" The fluorescent brighteners toilet paper has two main sources: First, recycled paper itself contains , the two manufacturers in the bleach is added later , but add a lot of argument is unscientific because FWA has yellowed points , its content is generally less than 1/1000 ( in paper weight basis ) , the paper will not exceed this amount but will whiten yellowed . " Shen Yongjia said.
In fact, in most countries, handkerchief production is also not explicitly prohibit the use of optical brighteners . In China, in order to avoid consumer concerns handkerchief only allowed to add fluorescent brighteners requirements.
"As for bleaching and spices , is the paper bleaching process . Corrosion and oxidation bleach although very strong, but after processing , basic does not remain in the pulp ; spices , as the paper is the human body may be, if not the sensitive skin or is the spice allergy , no problem . " Shen Yongjia that bleach and add flavor will not endanger human health.
"But the premise is qualified regular manufacturers of paper , like some sinister manufacturers out of inferior black iron oxide  products, sources of raw materials is very complex , and perhaps itself contains bacteria or harmful substances.
"For example , when we went unannounced visits , found some illegal dumping of waste paper manufacturers in one , and some have even moldy , braving the stench of these paper waste paper some life , such as sanitary napkins , disposable diapers are class , but also some some chemical scrap of paper from the paper products produced with a variety of fungi, E. coli, or there is a chemical, pesticide residues harmful to human health
