Sodium Phosphate

Description

Sodium Phosphate is a versatile inorganic compound widely used in skincare and cosmetic formulations. This salt of phosphoric acid serves multiple functions, including pH adjustment, buffering, and water softening. In skincare products, Sodium Phosphate helps maintain optimal acidity levels, ensuring product stability and enhancing the effectiveness of other ingredients.

As a buffering agent, it helps resist changes in pH when small amounts of acids or bases are added, contributing to the overall stability of the formulation. This property is particularly valuable in products containing active ingredients sensitive to pH fluctuations. Sodium Phosphate also acts as a chelating agent, binding to metal ions in hard water, which can improve the performance of cleansers and prevent the formation of soap scum.

In addition to its technical functions, Sodium Phosphate can indirectly benefit skin health by maintaining product efficacy and preventing irritation that may occur from pH imbalances. It's generally considered safe for use in cosmetics and is approved by regulatory bodies worldwide. However, as with any ingredient, some individuals may experience sensitivity, so patch testing is recommended for those with reactive skin.
