TETRAETHYL ORTHOSILICATE

Description

Tetraethyl orthosilicate, also known as ethyl silicate or TEOS, is a versatile silicon-based compound widely used in skincare formulations. This colorless, low-viscosity liquid serves as a precursor for silica and silicone materials, making it valuable in various cosmetic applications. TEOS functions as a film-forming agent, creating a protective barrier on the skin that helps retain moisture and improve product texture.

In skincare, tetraethyl orthosilicate is primarily utilized for its ability to enhance the stability and efficacy of formulations. It acts as a cross-linking agent, improving the overall structure and longevity of products. TEOS can also contribute to the mattifying effect in cosmetics, helping to control excess sebum production and reduce the appearance of shine on the skin.

When hydrolyzed, tetraethyl orthosilicate forms a silica network that can act as a delivery system for active ingredients, potentially improving their penetration and effectiveness. Its film-forming properties make it useful in sunscreens and anti-aging products, where it can help create a smooth, even application and provide a degree of environmental protection. However, formulators must carefully control its concentration to avoid potential skin irritation.
