Tear Film Stabilization via Emulsifier/Surfactant Effect (TFSE)
- Target
- TFSE
- Molecular classification
- Surfactant, Emulsifier, Ocular lubricant, Artificial tear component
01
Overview
Tear film stabilization via emulsifier/surfactant effect refers to a mechanism of action used by artificial tears and ocular lubricants to enhance the stability and function of the tear film, particularly its lipid layer. This is achieved by reducing surface tension and improving the spread and retention of lipids at the air-tear interface, thereby preventing rapid tear evaporation and maintaining ocular surface health. It is not a single target, but a functional mechanism involving various amphiphilic compounds.

02
Mechanism of action
Reduces surface tension at the air-tear interface, promotes uniform spreading and stabilization of the lipid layer, and prevents tear evaporation. Emulsifiers and surfactants align at water-oil interfaces to facilitate these effects.
