Sodium Silicate, alkaline

Sodium Silicate is defined as pH Buffer and belongs to a group of chemicals commonly called buffers. These chemicals have the property of maintaining the pH of an aqueous medium in a narrow range even if small amounts of acids or bases are added. Sodium Silicate is used to adjust the pH of a formulation to ensure a product's pH is stable over time for product stability and consumer safety. In addition it acts as corrosion inhibitor which are substances added to products in order to prevent the corrosion of metallic (and occasionally other) materials used for cosmetic packaging.
