Even more worrying is the lack of legal requirements to list the ingredients of such products on their labels. Many companies, claiming their formulas are "trade secrets," even refuse to release details to inspectors and researchers. Few customers take the time to look into these matters themselves--they just bring these cleaning products home by the can and bottle without ever realizing that they might be hazardous to health and environment.
更令人憂心的是，市售清潔劑的成分標示向來缺乏法令規範，許多公司甚至以「商業機密」為由，連對抽驗或研究單位都堅不吐露，而民眾也多不深究，竟放膽將瓶瓶罐罐往家裡買，卻從沒想過，本意是要用來清潔自身和環境的用品，到頭來卻導致環境和自己雙雙受害。
