Abstract

1295036 Aerosols containing microcapsules L'OREAL 4 Feb 1970 [4 Feb 1969] 5280/70 Headings C4X and C5D [Also in Divisions B1 B8 D1 and F1] A pressurized dispensing container contains a propellant fluid and at least one encapsulated mixture of a pressurized gas and a liquid, the pressure of the fluid being at least equal to that of the pressurized gas. When the fluid is dispensed, the capsules which have a diameter of from 50 to 1000 Á are also dispensed and burst due to the sudden decrease in pressure outside them. In one embodiment, the pressurized gas is the same as the propellant fluid, in which case one liquid is encapsulated in, for example, low melting point polyethylene and the capsules placed in the pressurized gas, whereupon the gas diffuses into the capsules. In another embodiment, a liquid is encapsulated in a pressurized gas atmosphere, then the capsules are placed in a propellant fluid. In this embodiment, substances which react with one another can be encapsulated separately, then the capsules can be mixed in the propellant fluid. The liquid may be a stain remover as disclosed in Specification 1295037 or may be a hair dye having the following composition: This encapsulated hair dye is mixed with a halogenated hydrocarbon propellant. An oxidizing agent may be added to the propellant, which will mix with the encapsulated hair dye when the capsules burst on being dispensed.
