Oxidation Hair Dye in a Plural-Fluids Dispensing Package
Issue Date:1977-03-08
•1 Claims
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.

Description
EXAMPLE I
The following compositions are utilized to prepare a package of the form illustrated in U.S. Pat. No. 2,973,883
Fill 96 parts by weight of Composition A into a pressure-tight container. Fill a collapsible container having a diameter smaller than the opening in the pressure-tight container with 100 parts by weight of Composition B. Insert collapsible container and affix valve means to communicate individually with the two compositions, the valve means being constructed such that actuation causes flow of Compositions A and B in the relative proportions of 1:1. Pressurize container with 4 parts by weight of a mixture of 84% isobutane -16% propane. Actuation of the valve means results in the mixing of portions of the two compositions to yield a hair dye which is dispensed at room temperature in a form ideally suited for hair dyeing purposes.
The following examples are illustrative of the preparation of packages in accordance with other embodiments of this invention:
EXAMPLE II
The following compositions are utilized to prepare a package of the form illustrated in U.S. Pat. No. 2,973,883:
A. Hydrogen Peroxide Composition
The composition is formulated as in Example I except that 30.00 parts of hydrogen peroxide (35% strength) are used.
B. Oxidation Hair Dye Composition (lt. auburn shade)
The composition is formulated as in Example I except that the ammonium hydroxide is increased to 19.14 parts and the following additional ingredients are added:
Sodium Thiosulfate 4.06 parts by weight
Sodium Molybdate Dihydrate 0.05 parts by weight
The compositions are packaged and the package is pressurized as described in Example I. Actuation of the valve means results in the mixing of portions of the two compositions to yield a hair dye which is dispensed in a warmed state in a form ideally suited for hair dyeing purposes.
EXAMPLE III
The following compositions are utilized to prepare a package of the form illustrated in U.S. Pat. No. 2,973,883:
A. Hydrogen Peroxide Composition
The composition is formulated as in Example I.
B. Oxidation Hair Dye Composition (lt. auburn shade)
The composition is formulated as in Example I except that the ammonium hydroxide is replaced by 19.14 parts by weight of monoisopropanolamine.
The compositions are packaged and the package is pressurized as described in Example I. Actuation of the valve means results in the mixing of portions of the two compositions to yield a hair dye which is dispensed at room temperature in a form ideally suited for hair dyeing purposes.
EXAMPLE IV
The following compositions are utilized to prepare a package of the form illustrated in U.S. Pat. No. 2,973,883:
A. Hydrogen Peroxide Composition
The composition is formulated as in Example II.
B. Oxidation Hair Dye Composition (light auburn shade)
The composition is formulated as in Example II except that the ammonium hydroxide is replaced by 22.0 parts by weight of monoisopropanolamine.
The compositions are packaged and the package is pressurized as described in Example I. Actuation of the valve means results in the mixing of portions of the two compositions to yield a hair dye which is dispensed in a warmed state in a form ideally suited for hair dyeing purposes.
EXAMPLE V
The following compositions are utilized to prepare a package of the form illustrated in U.S. Pat. No. 2,973,883 for the purpose of dispensing a hair dye in a warmed state of the shampoo-in type.
Fill 92 parts by weight of Composition A into a pressure-tight container. Fill a collapsible container having a diameter smaller than the opening in the pressure-tight container with 100 parts by weight of Composition B. Insert collapsible container and affix valve means to communicate indidivually with the two compositions, the valve means being constructed such that actuation causes flow of Compositions A and B in the relative proportions of 1:1. Pressurize container with 8 parts by weight of a mixture of 50% dichlorodifluoromethane and 50% 1,2-dichloro-1,1,2,2-tetrafluoroethane. Actuation of the valve means results in the mixing of portions of the two compositions to yield a hair dye which is dispensed in a warmed state in a form ideally suited for hair dyeing purposes.
The following Example is illustrative of the use of a propellant system modified by the presence of pentane to impart delayed foaming of a hair dye composition after application to the hair.
EXAMPLE VI
The following compositions are utilized to prepare a package of the form illustrated in U.S. Pat. No. 2,973,883 for the purpose of dispensing a hair dye.
Fill 100 parts by weight of Composition A into a pressure-tight container. Fill a collapsible container having a diameter smaller than the opening in the pressure-tight container with 100 parts by weight of Composition B. Insert collapsible container and affix valve means to communicate individually with the two compositions, the valve means being constructed such that actuation causes flow of Compositions A and B in the relative proportions of 1:1. Pressurize container with 16 parts by weight of a mixture of 50% pentane and 50% 1,2-dichloro-1,1,2,2-tetrafluoroethane. Actuation of the valve means results in the mixing of portions of the two compositions to yield a hair dye which is dispensed in a form ideally suited for hair dyeing purposes. Upon dispensing, the mixture is in the form of a thick, compact liquid which, after a time lag of 4 seconds, expands into a foam. The initial liquid state permits penetration of the composition to surround all hair on the head and the subsequent foam has good dimensional stability, thereby holding the composition to enable uniform dyeing action to take place.
The foregoing examples are illustrative of products within the scope of both the first and second product aspects of this invention. In all the examples, uniform proportioning of the two compositions is effected throughout the life of the package, even when the package is shaken prior to use. The following example is further supportive of the second product aspect of this invention in presenting a description of a dual-dispensed hot cleansing foam product:
EXAMPLE VII
Composition A is prepared by heating, with stirring, sub-compositions (i) and (ii) to 95.degree. C, cooling the mixture to room temperature and blending in the perfume.
Fill 20 parts by weight of Composition B into a pressure-tight container. Fill a collapsible container having a diameter smaller than the opening in the pressure-tight container with 80 parts by weight of Composition A. Insert collapsible container and affix valve means to communicate individually with the two compositions, the valve means being constructed such that actuation causes flow of Compositions A and B in the relative proportions of 4:1.
Pressurize container with 6 parts by weight of a mixture of 84% isobutane -16% propane. Actuation of the valve means results in dispensing of a warmed foam, ideally suited for facial cleansing purposes. Composition A is a highly foamable composition upon shaking. In spite of this property, uniform proportioning, as evidenced by uniform heat, results throughout the life of the package, brought about by the fact that the foamable composition is maintained throughout as a liquid column without head space.
It is to be understood that the invention is not to be limited to the exact compositions shown and described, as obvious modifications and equivalents will be apparent to one skilled in the art, and the invention is therefore to be limited only by the scope of the appended claims. The subject matter when the applicants regard as their invention is particularly pointed out and distinctly claimed as follows:
