Potassium perborate is a chemical compound often used as a bleaching agent and a cleaning product. It appears as a white, crystalline powder and is soluble in water. When dissolved, it releases hydrogen peroxide, which helps to remove stains and whiten fabrics. This compound is commonly found in laundry detergents and some dental products. It is considered a safer alternative to traditional bleach, as it breaks down into non-toxic byproducts. However, it should still be handled with care, as it can cause irritation to the skin and eyes.
