Aminopropyl Triethoxysilane description

Aminopropyl triethoxysilane is a synthetic texture enhancer that also helps modify the surface of other ingredients. For example, it can help make water-phobic ingredients more water-loving and also enhance the performance and aesthetics of UV filters such as titanium dioxide. Derived from silicone, aminopropyl triethoxysilane is sometimes used in dispersions with film-forming ingredients. This ensures a product such as a cream or lotion applies and distributes its key ingredients evenly. This ingredient may also be used to crosslink polymers in water-based solutions, creating pleasant-feeling gel textures with good adhesion properties.
