Sodium bicarbonate, also known as baking soda, is a chemical compound with the formula NaHCO3. It is a white, crystalline powder that is commonly used in cooking, baking, and as a household cleaning agent. Sodium bicarbonate has a wide range of applications due to its various properties, including its ability to act as a leavening agent, antacid, and mild abrasive.
As a gentle abrasive, sodium bicarbonate aids in the removal of dead skin cells, promoting smoother and softer skin texture. Its natural deodorising qualities have also positioned it as a valuable ingredient in natural deodorants, helping to control unpleasant odours by adjusting the pH of the skin and creating an environment less conducive to the growth of odour-causing bacteria.
In addition to its role in skincare, sodium bicarbonate is utilied in various hair care products. Its clarifying properties make it suitable for removing product buildup from the hair and scalp, contributing to a cleaner and refreshed feeling.
