Sodium percarbonate is a chemical compound that is commonly used in laundry detergents and stain removers as a powerful cleaning agent. It is also known as sodium carbonate peroxide or oxygen bleach.

When sodium percarbonate is mixed with water, it releases hydrogen peroxide and soda ash, which help to break down and remove stains and dirt from clothing. It is particularly effective in removing tough stains such as coffee, wine, and blood.

To use sodium percarbonate in your laundry, you can add it directly to the washing machine along with your regular detergent.
