What it is
SPF lotion sprays carry UV filters in a thin emulsion that a pump or trigger spray lays down as a fine mist. They make body coverage and reapplication quick, but enough product must be applied and rubbed in for even cover. Clear alcohol-based sprays and aerosols are a separate build.
Propellants need impurity controls, including for benzene.
