INCI: Sodium bicarbonate

What is Sodium bicarbonate?

Sodium bicarbonate, also known as baking soda, is a chemical compound that exists as a white crystalline solid. It is obtained from a natural mineral called nahcolite and has a wide variety of uses, including in baking and cooking, as a mild disinfectant, fire extinguisher, and as an antacid in medicines.

Use & Benefits:

Abrasive Agent: Sodium bicarbonate functions as an abrasive in cosmetic and personal care products. It helps remove dirt and dead cells from the surface of the skin, keeping it clean and protecting it from infections such as acne.

Buffering Agent: As a buffering agent, sodium bicarbonate helps maintain the normal pH balance of the skin. The sebaceous glands, sweat glands, and natural flora of the skin keep it slightly acidic, known as the acidic mantle. This provides protection from external factors such as microbes, irritants, and exposure to harmful rays. Maintaining the normal pH balance of the skin is important to prevent detrimental effects such as itching and depletion of vital lipids.

Skin Protecting Agent: Sodium bicarbonate also functions as a skin-protecting agent. It helps in reducing premature aging and skin irritation.

Deodorizing Agent: Sodium bicarbonate is used in deodorants to mask, reduce, or eliminate undesirable odors in the product as well as on the skin.

Oral Care: Sodium bicarbonate is used in formulations of oral care products for whitening teeth and removing plaque.

Other Applications: Sodium bicarbonate is used in creams, lotions, gels, bath, and other skin and hair care products.
