Description
This powerful alkaline compound serves as a pH adjuster in skincare formulations, helping to balance acidity levels and optimize product effectiveness. It's commonly used in very small amounts to neutralize acids and ensure products maintain the proper pH for skin compatibility. Due to its caustic nature, it requires careful handling during manufacturing and should only be present in finished products at safe, diluted concentrations.
