What it is + why it's regulated

Sodium tetraborate, commonly known as borax, is a naturally occurring mineral often used in laundry detergents, cleaning products, and as a pesticide. You might also find it in cosmetics, ceramics, and some industrial processes. The European Chemicals Agency (ECHA) has placed borax on its Candidate List of Substances of Very High Concern because it is classified as toxic for reproduction. This means that exposure to borax may harm fertility or cause harm to an unborn child. The listing does not mean that every product containing borax is dangerous, but it signals that regulators are carefully monitoring its use to protect human health. If you see borax in a product, it is a good idea to follow safety instructions, like avoiding inhalation or prolonged skin contact. This summary draws on public regulatory data; the linked source is authoritative. Source: ECHA Candidate List (https://echa.europa.eu/candidate-list-table).
