Overview

Sodium lactate is a sodium salt of lactic acid. Normally supplied pre-diluted in water, this ingredient appears as a yellowish liquid.

Its main function is as a humectant, which is a type of moisturizer that works by drawing water into the outer layers of the skin from deeper layers of the skin or even from the environment. Due to its nature as a sodium salt, sodium lactate is also weakly basic. This means it can serve as a pH adjuster by increasing the pH of a skincare product.

Additionally, this ingredient can be used as a chemical exfoliant, due to its close chemical relation to lactic acid.
