nonpersistent
Quick to fade
Nonpersistent describes something that doesn't last or remain in place.
In computing, nonpersistent data disappears when a session ends or a system restarts—nothing is saved to permanent storage.
In chemistry and environmental science, nonpersistent pesticides break down quickly rather than lingering in soil or water.
The term contrasts with persistent across technical fields: a nonpersistent connection, nonpersistent cookies.
