Sodium Silicate and Sodium Metasilicate are inorganic salts. In cosmetics and personal care products, these ingredients are used in skin care, hair coloring, shaving, bath, eye make up and oral hygiene products.

They function as a buffering agent, corrosion inhibitor and a pH regulator in cosmetics. Buffering agents are chemicals which have the property of maintaining the pH of an aqueous solution in a narrow range even if small amounts of acids or bases are added. Buffering agents and pH adjusters are used in cosmetics to alter and maintain a product's pH at the desired level.

Sodium Silicate and sodium Metasilicate are also used to prevent the corrosion (rust) of metallic materials used in cosmetic packaging.

Attention must be paid to formulated them to avoid irritation.
