Function as buffering agent and preservative:
•    Sodium citrate is used in a variety of cosmetic products as a buffering agent and preservative.

Maintain normal pH balance of the skin:
•    The pH of the skin is slightly acidic, known as the acidic mantle, and is maintained by the sebaceous glands, sweat glands, and natural flora of the skin.
•    Sodium citrate helps to maintain the normal pH balance of the skin and prevents detrimental effects such as itching and depletion of vital lipids from the skin.
•    pH adjusters or buffers maintain this pH balance of the product and avoid the skin’s pH from shifting too far from the normal one.

Reduce premature aging and skin irritation:
•    Sodium citrate helps in reducing premature aging and irritation of the skin.

Increase the shelf life of cosmetic products:
•    As a preservative, it inhibits the growth of molds, fungus, or bacteria in the product.
•    It increases the shelf life of the product so that the aroma, taste, and cosmetics themselves can be stored for a longer period of time.
•    It protects the product from getting deteriorated with time.

Used in a variety of cosmetic products:
•    Sodium citrate is used in the formulations of creams, lotions, gels, make-up products, shampoos, conditioners, hair styling, and other skincare products.
