Furlong 5 7] ABSTRACT 8 Claims, N0 Drawings DISPENSING PACKAGE FOR TWO-PART HAIR- TREATlNG COMPOSITIONS This invention relates to packaged hair or skintreating compositions and pertains more specifically to a package containing a two-part composition, one part containing hydrogen peroxide, the parts of which are arranged to be mixed immediately before or as they are dispensed from the package.

A variety of peroxide-containing hair and skin-treating compositions must be alkaline in reaction at the time of application to the hair or skin in order to achieve maximum effectiveness. However, because of the instability of aqueous alkaline peroxide solutions, as well as because of the interaction of hydrogen peroxide with other ingredients in most of the compositions, it has been essential to package such compositions so that the ingredients are contained in two separate compartments, one part or component of the composition comprising aqueous acidic hydrogen peroxide, and the other including the alkaline components ofthe composition. Among such compositions are hair dyes and bleaches, hair lightening agents, hair lightening shampoos or setting compositions, and the like.

There are also various hot hairor skin-treating compositions such as hot shaving preparation compositions, hot skin cleansers, hot hair conditioning agents, and the like which utilize the reaction of hydrogen peroxide with one or more ingredients of the base composition for generating heat, the reaction usually being carried out in an alkaline medium. Accordingly, in the case of these compositions also the aqueous acidic hydrogen peroxide component is kept in a compartment separate from the other components.

It has been proposed to package such compositions in two compartment containers with or without a pressure propellant for ease and convenience in dispensing, as set forth for example in British Pat. No. 1,125,528 and U.S. Pat. Nos. Frangos 3,272,389, Moses 3,341,418, and Schroeder et al., 3,402,855. in the case of such packages, however, there is a risk of leakage between the compartments. Furthermore, particularly in the case of containers in which the components are separated by a flexible wall of synthetic polymer or plastic such as polyethylene, polypropylene, cellulose acetate or the like, even though leakage is completely eliminated by careful manufacture and inspection procedures, there is a problem of actual permeation ofan alkalizing agent or alkaline ingredient through the permeable wall. In addition, in the case of packages in which mixing occurs simultaneously with dispensing of the components, there is a risk of some back flow of components from one compartment to the other through the valving mechanism during the dispensing, particularly at the beginning or end of each dispensing step. While the amount of such back flow during any particular actuation of the dispensing mechanism is quite small, the cumulative amount in the case of repeated actuations of the dispensing mechanism can be sufficient to increase substantially the instability of the peroxide solution component and consequently the risk of its decomposition before all of the contents of the package have been dispensed. Such decomposition, if it extends far enough, not only will render ineffective and useless whatever portion of the components remains unused in the package, but may actually lead to a dangerous increase in pressure within the package or container.

in accordance with the present invention, it is found that despite the necessity for having sufficient alkaline material or alkalizing agent present in the second component of the composition to provide a pH from 7 to 12 in the final composition after mixing of the components, it is possible to improve the stability of the aqueous acidic peroxide composition and decrease the risk of its decomposition by including in it an acid buffer which produces a pH from 2.5 to 6.5. The aqueous acidic peroxide component may contain from 0.5 to percent hydrogen peroxide by weight, and the buffer present in this composition may amount to 0.1 to 8 percent by weight of the total aqueous peroxide component.

LII

Any conventional stabilizer may also be present in the peroxide component such as hydrochloric acid, sulfuric acid, acid sulfate salts, pyrophosphates, silicates, stannates, or the like, as well as organic stabilizers such as phenacetin, or the like.

A wide variety of conventional acid buffers can be used in the present invention such as combinations of citric acid with sodium citrate or with disodium phosphate or with mixtures of sodium chloride and sodium hydroxide; combinations of acetic acid with sodium acetate; and potassium acid phthalate either along or in combination with sodium or potassium hydroxide. Potassium acid phthalate alone is the preferred buffer.

The second component of the composition, stored in a compartment separate from the peroxide component, includes an alkalizing agent and whatever other ingredients are needed to complete the desired hair or skin treating composition. The alkalizing agent may include a fixed alkali such as sodium or potassium hydroxide as well as such materials as ammonium hydroxide and various amines including short chain al kanolamines such as monoethanolamine. Any of the conventional ingredients commonly employed in such hair or skin treating compositions may also be present, such as soaps, wetting agents, foaming agents, detergents, dye intermediates and modifiers, germicides and bactericides, hair conditioning and skin conditioning ingredients particularly quaternary ammonium compounds which may act both as germicides or bactericides and conditioners, reactants which generate heat when mixed with the peroxide component, emollients, softeners, thickening agents, setting agents, and other ingredients commonly employed in cosmetic compositions.

The relative proportions of alkaline ingredients in the second component and the acid materials and buffers in the first component must be such that the pH in the final composi tion after mixing of the components is from 7 to 12 in order to provide optimum results. Despite the requirement for such a large proportion of alkaline ingredients, however, it is found that the presence of the buffer of the present invention in the acidic aqueous peroxide solution is effective to insure against instability of the peroxide component under normal conditions ofstorage and usage.

The following specific example is intended to illustrate more fully the nature of this invention without acting as a limitation upon its scope.
