Hotels **** towels why so white fluorescent whitening agent is the secret

I have to Wuhan Quality Supervision Bureau, Wuhan CDC, Wuhan Food and Drug Administration and other relevant departments to apply for testing these towels contain fluorescent whitening agent. But the reply said, there is no such test, because as a government department, its test only for the project with **** standards, and fluorescent whitening agent is not included.

After several contacts, on August 22, I will obtain the 8 towel samples, according to the packaged and unpackaged into two categories, randomly selected 5 samples sent to SGS Standards Technical Services (Shanghai) Co. The company is SGS Group and affiliated to the former **** Quality and Technical Supervision of the China Standards Technical Development Company built in 1991, a joint venture, for the global scope of providing authoritative inspection, identification, testing and certification services, including agriculture, chemical and other fields. September 2, sent for inspection of the five towels have results: five samples contain fluorescent whitening agent.

According to reports, this test result explains the hotel **** towel why so "white": with the help of fluorescent whitening agent, may have been yellowish, old towels can be successfully turned into a very white "new" towel.

According to a large catering enterprises in Wuhan, an employee revealed that the hotel table with **** towels, generally there are two **** ways. One is provided by a specialized cleaning company, towels by recycling **** packaging and then sent back to the table to use, the other is the catering enterprises for their own ****, the **** method is to "cook".
