Citric acid is a powder obtained through fermentation of fruit sugars sometimes called sour salts. As a food additive, it acts as an emulsifier, preventing fats from separating. It can add an acidic, sour flavor to foods in place of liquid such as lemon juice. The powder is added to bath salts to add fizz and soften hard water. In cosmetics, it is used to extend shelf life, balance pH, and is one of the ingredients used in chemical peels. It is also added to scouring powders to bind metals and remove lime and rust deposits.
