What is Sodium Carbonate?
Sodium Carbonate, often referred to as soda ash or washing soda, is a white, water-soluble salt commonly used in cleaning products. It is derived from sodium chloride (table salt) and limestone through a process called the Solvay process.
In consumer products, sodium carbonate is used primarily for its properties as a water softener and pH adjuster. It is found in toothpaste to aid in cleaning and in dishwasher detergents for its effectiveness at cutting through grease. Health-wise, sodium carbonate is generally regarded as safe when used appropriately, although it can be irritating to the skin and eyes in concentrated forms.
When you see sodium carbonate on a label, it's typically used to enhance the performance of the product in cleaning or pH balance, rather than as an ingredient affecting taste or nutrition.
