Sodium Silicate
What is Sodium Silicate?
Sodium Silicate, often known as waterglass or liquid glass, is a compound made by fusing sodium carbonate and silicon dioxide. It typically appears as a white powder or crystal but can also be dissolved in water to form a viscous liquid.
In commercial products, sodium silicate is used as a binder, adhesive, or flocculant. In toothpaste, it helps maintain the product's texture and stability, whereas in dishwashing detergents, it aids in breaking down grease. Health-wise, there is limited data on the effects of sodium silicate in consumer products, and it is generally considered safe for these uses.
When checking labels, note that sodium silicate should not be consumed in its raw form — it's intended for specific applications where it's neutralized or transformed during the product's use.
Commonly found in: Toothpaste, Dishwashing Detergents, Paints, Cement, Textile Treatment
Sodium silicate is generally recognized as safe (GRAS) when used within specified limits in consumer products.
Research indicates sodium silicate's effectiveness in its intended uses, though there is no significant data suggesting health risks at typical exposure levels.
Sodium silicate is mineral-based and usually considered vegan-friendly, as it contains no animal-derived components.
