Abstract
Disclosed herein is an aerosol package and method using this package for dispensing substances in spray form and depositing them on a desired limited surface area in the form of a buttery, liquescent solid. The aerosol packaging contains an anhydrous, oleaginous base containing specified fats or waxes and a propellant miscible therewith.
Claims10
An aerosol package for spraying a cosmetic or pharmaceutical substance such that it deposits on a desired limited surface area of living skin tissue in the form of a buttery, liquescent solid comprising a pressure-resistant container;
- actuatable aerosol spray valve means for hermetically sealing said container and regulating the passage of material therethrough such that it leaves the terminal orifice as a finely divided spray, said container housing an anhydrous cosmetically or pharmaceutically acceptable, oleaginous base containing said substance;
- a wax in an amount of about 5 to 50% by weight of the base, said wax being a paraffin wax having a melting point in the range of 120.degree. to 150.degree. F.;
- and an effective amount of a propellant miscible with said base.
A method of forming from a cosmetic or pharmaceutical substance and a base a buttery liquescent solid comprising the steps of:
- a. loading a pressure resistant container having an actuatable aerosol spray valve means for hermetically sealing said container and regulating the passage of material therethrough such that it leaves the terminal orifice as a finely divided spray;
- with the following:
- an anhydrous cosmetically or pharmaceutically acceptable, oleaginous base containing said substance;
- a wax in the amount of 5 to 50% by weight of said base, said wax being a paraffin wax having a melting point in the range of 120.degree. to 150.degree. F., and
- an effective amount of a propellant miscible with said base,
- b. directing said terminal orifice toward a desired limited surface area of living skin tissue and at a spaced distance therefrom, and
- c. spraying said base and substance by actuating said aerosol spray valve means to form said buttery liquescent solid.
