Most detergents are chemical products, detergents content of a large number of large wastewater discharged into rivers , water quality will deteriorate . Long-term use of improper cleaning agents can damage the human central nervous system , people’s mental retarded, thinking ability , analytical ability to reduce , there will be severe mental disorders.
