Descriptif
Sodium Citrate is the sodium salt of citric acid, a small, water-soluble ingredient that shows up in many skincare and haircare formulas. Its main job is to help adjust and stabilize pH, which matters because a product that is too acidic or too alkaline may feel less comfortable and can be less effective. It also acts as a chelating helper, meaning it binds to trace metal ions from water or raw materials so they are less likely to interfere with the formula.
For skin and hair, Sodium Citrate is mostly a behind-the-scenes support ingredient rather than an active treatment. By helping keep the formula at the right pH, it can make cleansers, toners, serums, shampoos, and conditioners feel more balanced and perform more consistently. It can be especially useful in products that contain acids or other pH-sensitive ingredients.
Most people won’t notice Sodium Citrate on its own, and it is generally used at low levels. If a formula is poorly balanced, though, even a helpful ingredient like this can’t fully fix it. In very sensitive skin, the overall product formula matters more than Sodium Citrate itself, so it’s best to look at the whole ingredient list and how the product feels on your skin or hair.
