Used primarily as an antiviral agent, especially in the topical treatment of cold sores caused by herpes simplex virus type 1 (HSV-1). It works by inhibiting the fusion of the viral envelope with the human cell membrane, preventing the virus from entering and infecting healthy cells. Commonly found in over-the-counter lip and face creams, it helps reduce the duration and severity of outbreaks when applied at the first sign of symptoms.

Also used in cosmetic formulations for its skin-conditioning properties, contributing to moisturization and barrier protection.

In industrial applications, 1-Docosanol serves as an intermediate or additive in lubricant formulations or certain coating materials due to its thermal stability and natural surfactant properties.
