How to read Japanese bleach labels

When comparing bleach (漂白剤) sold in Japan, the mandatory label block on the back or side of the package provides the exact ingredient breakdown required under Japan's Food Labeling Standards (or Household Goods Quality Labeling Act for detergents and cosmetics). On Urayomi, we photograph or verify the official manufacturer disclosure for each item and separate base ingredients from auxiliary chemical agents.

Products reviewed on this shelf include グラフィコ オキシクリーン パワーリキッド 本体 660mL (オキシクリーン（グラフィコ）, no auxiliary agents), 花王 ワイドハイター EXパワー 本体 560ml (花王, no auxiliary agents), 花王 ワイドハイター PROリキッド 抗菌 本体 560ml (花王, 2 added components) and ミヨシ石鹸 暮らしの酸素系漂白剤 750g (ミヨシ石鹸, no auxiliary agents).
