Every line below is in CPSC’s own words, with its source beside it.
What’s wrong with it?
The products contain sodium hydroxide or potassium hydroxide which must be in child resistant packaging, as required by the Poison Prevention Packaging Act (PPPA). The packaging of the products is not child resistant, posing a risk of chemical burns and irritation to the skin and eyes. In addition, the label on the product violates the Federal Hazardous Substance Act (FHSA) by omitting the word “poison” for poisonous chemicals.
