Purchase products with clear, complete label information: Many product labels merely say the product "doesn't contain" such-and-such without plainly telling you what it does contain. For example, those who only buy products labeled "doesn't contain bleach" due to allergies should make sure to read the fine print on the labels as well.
四、選擇標示完整、清楚的商品：通常廠商只會特別標榜「不含」某種物質，但不一定會一一誠實地標示含有哪些物質，因此若對漂白劑過敏者，一定要選購標示「不含」者，而勿輕信成分內容標示。
