ABSTRACT:
A non-staining antiperspirant spray powder comprises an antiperspirant powder, such as aluminum chlorohydrate, an encapsulated surface active material, such as a liquid, nonionic surface active agent, with the encapsulating material about it being soluble or disruptable by aqueous media and insoluble in the propellant, and a propellant fluid under pressure. The composition is discharged from a container as a powder spray, preferably onto the axilla, by the opening of a discharge valve. The presence of the surface active agent diminishes staining of clothing contacted by the antiperspirant and its encapsulation in a soluble encapsulant allows the gradual release of surface active agent as the aluminum chlorohydrate is activated by the presence of perspiration, while also maintaining the dry character of the powder spray and preventing or diminishing mucous membrane irritation during spraying. Also disclosed are methods for utilization of the described compositions and methods for applying surface active agent to surfaces without causing mucous membrane irritation.
