Abstract
Packages are described wherein two compositions are maintained isolated from each other within a container, the first composition comprising an oxidation hair dye and the other comprising hydrogen peroxide. The container is fitted with valve means which communicate with each composition, actuation of the valve means resulting in mixing of portions of each composition and dispensing of the mixture as a hair dye. Through the addition of a reducing agent or a hydrogen peroxide decomposition catalyst to the first composition, the hair dye can be dispensed in a warmed state. A process for packaging of plural fluids to insure uniform dispensing in which one is a foamable liquid is described wherein the foamable liquid is placed within an inner compartment within a container separated from the remainder of the container by a movable wall and a pressurized fluid is placed inside the container outside the inner compartment.
