Abstract

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.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 136 words
A dispensing package having two compartments, one compartment containing one part of a two-part oxidative hair dye composition, the other compartment containing the other part of said composition, and means for mixing said parts including a pressure propellant to dispense said parts together, said one part comprising an aqueous solution containing an alkaline material selected from the group consisting of ammonium hydroxide, and short chain alkanolamines, said other part comprising an aqueous solution having a pH of about 3.75 containing from about 5.95 to about 10.5 percent hydrogen peroxide and about 0.1 percent phosphoric acid by weight, the amount of alkaline material in said first part and the amount of phosphoric acid in said other part being such as to provide a pH of about 8.5 to about 10.0 in the two-part composition immediately after mixing.
Claim 2
Dependent Claim 136 words
A dispensing package having two compartments, one compartment containing one part of a two-part oxidative hair dye composition, the other compartment containing the other part of said composition, and means for mixing said parts including a pressure propellant to dispense said parts together, said one part comprising an aqueous solution containing an alkaline material selected from the group consisting of ammonium hydroxide, and short chain alkanolamines, said other part comprising an aqueous solution having a pH of about 3.75 containing from about 5.95 to about 10.5 percent hydrogen peroxide and about 0.1 percent phosphoric acid by weight, the amount of alkaline material in said first part and the amount of phosphoric acid in said other part being such as to provide a pH of about 8.5 to about 10.0 in the two-part composition immediately after mixing.
