Main effects of fluorescent brighteners on environment

(1) HIGH degradation of CBS  

CBS in detergent use is not high, after rinsing dilution, domestic sewage after a general treatment, CBS can be reduced by more than 95%, and the final amount into the environment is very little.  Even if a small part enters surface water (such as rivers), it will undergo photodegradation very quickly. The photodegradation products are also easy to undergo secondary degradation, that is, they will be eaten by microorganisms and decomposed into carbon dioxide and other substances that have no impact on the environment.  

(2) No impact on the biological chain  

CBS is a water-soluble fluorescent whitening agent that does not remain in biological tissues and organs after being ingested by fish.  Laboratory studies have shown that even fish exposed to high levels of CBS for a period of time do not accumulate CBS after two days out of the environment.  

Based on long-term ecological studies, CBS is not harmful to the environment.
