Caustic soda flakes are white granules or flakes which quickly dissolve in water to give a robust alkaline solution. It is very corrosive and can cause severe burns, eye damage or blindness if it comes into contact with skin or eyes. They are heavier than water, so they will sink to the bottom of storage containers, making them ideal for use in drains and sewers where they can break down fats, oils and greases.
