Abstract
Abstract A hair setting lotion composition comprises in combination an aqueous solution of a lower alkanol, a cosmetic film-forming resin and a reducing agent selected from the group consisting of butyl hydroxy anisole, dodecyl gallate, propyl gallate and octyl gallate. The reducing agent is generally present in amounts of about 0.02-2% by weight of the composition.
