Sonett Bleach Complex is based on sodium percarbonate and during the washing and bleaching process this compound disintegrates into mineral soda, water, and oxygen. It can be used for bleaching white laundry, for removing stains (particularly oxidizable stains such as fruit, red wine, tea, coffee, grass, blood, etc.), and for brightening yellowed and greyish laundry. Due to the absence of petrochemical bleaching agents, it is only effective in the washing machine from 50°C upwards. It is effective from 30°C if soaking for longer periods, e.g. if the laundry is soaked overnight prior to washing.
