Instant degreasing and antibacterial effects: Ethanol cleanses skin oils and can disinfect the skin surface (effective against bacteria and viruses at sufficient concentrations). It gives an immediate matte, cooling feel and helps other ingredients penetrate by breaking down oil residues. In hand sanitizers and some lotions, ~60–70% ethanol is used for its proven germ-killing ability. Caution: Frequent use can over-dry and irritate skin by depleting natural lipids, so it’s beneficial primarily in targeted or short-contact applications (like toners for oily skin or sanitizers) where its antimicrobial and quick evaporation properties are desired.
