Is fluorogenic brightening agent the essential composition doing washing in the articles? Use the dispute of the safe problem of fluorogenic brightening agent to the detergent, the industrial association of Chinese articles for washing holds the news briefing on the 2nd, relevant domain experts such as toxicology, medical science, textile,etc. respond consumers' doubt. Can fluorogenic brightening agent be used in the articles for washing? Shen Yongjia, Professor of East China University of Science and Technology, says, fluorogenic brightening agent is presented colourlessly or pale yellow ( greenly) Organic compound of the color. Through absorbing the ultraviolet ray, macroscopic violet-blue fluoro appears in transmission, remedy the white material incurred because of blue mere defect and yellowing effectively, improving white degree and luminance of the white material notably visually. "Add fluorogenic brightening agent into detergent of clothes, can let the clothes try hard to resume original white degree and color. Do not cause injury, characteristics such as water soluble, stability and brightening the result to the fiber evenly obviously,etc., make it generally apply to the textile industry. " Yu FanQin, researcher of China Textile Academy, says. Meanwhile, limite by its technology of prescription, detergent can only the trace accede to with fluorogenic brightening agent, if excessive joined not only can't increase the clean result, will make the clothes yellow instead. The clothing of our country is generally joining amount in 0.02% to 0.4% in the detergent products, it is slightly low or about equal to compare with Europe, U.S.A. and Japan. The national development and reform committee releases on March 12, 2008, " the detergent uses fluorogenic brightening agent " (QB/ T2953- 2008) for the sector standard implemented on September 1, 2008 ,Point out clearly there are two kinds of fluorogenic brightening agent that can be used for producing the detergent of fabric: " two benzene vinyl unites benzene types " With " two amino styrene of a pair of three piperazine " . Is fluorogenic brightening agent harmful to environment? Professor of Tongji University of Central China University of Science and Technology medical college Wu Zhi just showed, the sanitary sewage was after generally dealing with once, fluorogenic brightening agent can be reduced by more than 95%. Under the illumination condition of the river system, CBSs only have 48 minutes in fluorogenic brightening agent half-life, have 3 hours only too in half-life of 33 # fluorogenic brightening agent, they are easy to be degraded by the living beings, can exclude the possibility that brightening agent is accumulated in soil and water areas. Many experts think, can draw the conclusion according to the research of environmental ecology, the detergent is easy to degrade in the environment with fluorogenic brightening agent, the application in the detergent of fluorogenic brightening agent that the standard stipulates is safe.
