Sodium percarbonate is basically a "friendly", safe, non-toxic, biodegradable alternative to chlorine bleach. It is also called oxygen bleach.
When dissolved in water (over 50°C), it releases oxygen which acts as a powerful stain remover and disinfectant. It's ideal for whitening, deodorising or whitening old linens and yellowing whites. Sodium percarbonate does not create harmful fumes like chlorine bleach.
