A silicon-based binding agent. It helps anchor actives on skin and support the film. Well tolerated.
Topical application
BLimited evidence. One RCT or several controlled studies with limitations.
A functional silicon-based ingredient. Safe.
Aminopropyl triethoxysilane (INCI Aminopropyl Triethoxysilane) is a silicon compound that acts as a binding agent. In a formula it helps anchor other ingredients on the skin and hold an even film, which improves how the product sticks. This is a functional component, not a skincare active. It does not hydrate or treat; its work is technical, binding and holding the film. Any skin effect comes from the ingredients it helps to fix, not from itself. Applied topically it is not systemically relevant, so it can be used during pregnancy and breastfeeding without issue. Tolerability is good. Irritation and allergy potential are both low, suitable for sensitive skin. There is no data pointing to relevant comedogenicity.
