C08MBTICS CONTAINING RE MINERALIZED WAq!lER
BACRGROUND OF THE INVENTII:)N
1. Field of the Invention The invention relates to cosmetic products and toiletries containing small amounts of mineral substances.
2. Description of the Prior Art It is customary for aqueous base cosmetics and toiletries to be made with water that has been highly purified and demineralized so as to reduce the likelihood of undesirable chemical and physical reactions occurring during the formulation of the products. Such reactions might compromise the appearance, texture or functionality of the given product. For example, iron (a typical trace metal found in many water supplies) can react with many perfume ingredients to cause a darkening of the finished product and degradation of the fragrance. This may or may not affect the function of the product, but will certainly give consumers the impression that the product is somehow spoiling or becoming rancid.
It is, therefore, normally considered essential to remove all traces of iron and other minerals from water to be used in compounding cosmetic or toiletry products. This is accomplished by distillation, reverse osmosis, ion-e.xchange treatment and other suitable processes which remove not only iron but most other trace metals, metallic salts and other minerals from the water.
2 ~
The net effect o~ the above-descxibed conventional procedure for demineralizing water prior to its use in cosmetics and toiletries is that even minerals which would be of benefit to the skin or scalp, thus improving the function and effectiveness of the products, or which might improve the in-use or ~fter-use feel of the product, are removed from the water used in aqueous base products together with truly undesirable minerals.
Recognizing that the presence of certain minerals in cosmetics and toiletries imparts valuable and useful properties, some manufacturers of these products have adopted a technique of adding trace minerals, for example, iron, selenium, silicon, magnesium and calcium, to their cosmetic formulations. These minerals are added, however, to finished cosmetic vehicles or total cosmetic formulations, which makes it difficult and costly to accurately analyze and assay the precise concentration of the minerals in the cosmetics. The difficulty in obtaining accurate analysis can lead too low a level of the added minerals, in which case the value of the minerals in the product is decreased or eliminated, or too high a concentration, which may lead to product instability and/or ineffectiveness. For example, minerals such as calcium and magnesium, if present in significant concentrations, may deactivate surfactants and detergents, leading to a decrease in the foaming and cleaning ability of shampoos, bath gels and the like. Deactivated surfactants can also cause physical instability of emulsion systems in lotions, creams and other water and oil emulsions.

~UMM RY OF THE INVE TION
It is the obj ect of the present invention to overcome the foregoing drawbacks in the prior art and to provide cosmetic and toiletry compositions with accurately analyzed, low concentrations of minerals, mineral complexes and/or mineral salts to improve the function and/or feel of the product.
It is a further object of the present invention to provide a novel method for incorporating trace minerals, mineral complexes and/or mineral salts into cosmetic and toiletry compositions which is simpler, less expensive and more accurate than prior techniques for producing such mineral-containing compositions.
In keeping with these objects and others which will become apparent hereinafter, the invention resides, ~riefly stated, in the production of aqueous base cosmetic and toiletry compositions using water that is first purified and demineralized in accordance with conventional procedures and then re-mineralized with precise, low concentrations of minerals (e.g., in the form of metal salts or metal-protein complexes) known to confer beneficial properties on the particular composition. This re-mineralization o~ water with the desired trace minerals prior to incorporation of the water into the cosmetic or toiletry formulations enables accurate analysis of the concentration of minerals present and avoids many of the problems inherent in the prior art procedures wherein totally demineralized water i~ used to formulate products and minerals are subsequently added to the formulat~ons.
2 ~
DE~AILED DE~RIPTION OF THB INVENTION
The novel compositions of th~ present invention are aqueous base cosmetic or toiletry compositions intended for application to the skin, scalp, hair or nails, e.g., skin creams, lotions, moisturizers and cleansing agents, shampoos, hair conditioners, color cosmetics (colored lip, face, eye and nail cosmetics) and the like, based on aqueous formulations and produced using water which has first been substantially deminerali7ed to remove all traces of metals, metal salts, silicon compounds and other minerals which, if present to a significant degree, could interfere with the function, stability or appearance of the composition, and then re-mineralized prior to incorporation into the compositions with one or more minerals whose presence is beneficial in the particular cosmetic or toiletry composition, either improving its appearance, in-use or after-use feel, its functionality or its effectiveness. The total or aggregate concentration of such minerals in the water after re-mineralization is in the range of about 0.005 to about 0.2% by weight.
As used herein, the term "minerals" comprehends inorganic metallic and non-metallic elements, salts and compounds which originate in the earth's crust. The phrase "substantially demineralized water" as used herein refers to water that has been treated by any conventional means (e.g., distillation, reverse osmosis or ion-exchange treatment) to remove minerals to the extent that less than ten parts per million (.001%) of minerals, in the aggregate, remain.
The present invention also comprehends the novel method of producing mineral-containing cosmetic and toiletry compositions by first demineralizing the water to be incorporated into the compositions, then re-mineralizing the water by dissolving in it from about 0.005 to about 0.2% by weight of one or more minerals conferring a benefit on the compositions in terms of their appearance, feel, functionality or effectiveness, the re-mineralization taking place prior to incorporation of the water into the compositions.
A preferred concentration range for said minerals in the re-mineralized water, for purposes of the novel compositions and methods, is from about 0.01 to about 0.15% by weight.
The minerals contemplated by the present invention for re-mineralization of water to be added to aqueous base cosmetic compositions are those known to have beneficial properties when incorporated into topically applied cosmetic, cleansing or toiletry compositions, either by providiny mineral nutrients of benefit to the skin, scalp, hair and nails or by improving the "feel" (smoothness, lubricity, absorption) of the cosmetic or toiletry composition as a whole. Such minerals would include, by way of illustration, and not limitation, calcium sulfate, magnesium sulfate and combinations thereof which, in the low concentration levels specified for compositions of the invention, enhance the in-use and after use feel of cosmetics and toiletries and the skin and scalp treated therewith in terms of smoothness, softness and suppleness; and salts or protein complexes of elements such as iron, copper, zinc, selenium, silicon, magnesium, calcium, chromium, cobalt, manganese and nickel. Such protein complexes are available, for example, under the BIOMINTU
trademark from Brooks Industries (South Plainfield, NJ), and have a variety o~ useful effects when incorporated into cosmetics and toiletries. The mineral-protein complexss can enhance the absorption of the nutrient minerals by the skin and scalp, and may also enhance systemic absorption cf minerals such as iron and zinc. If metal-protein complexes are used, the percentage concentration of minerals addsd to the water is calculated based solely on the amount of metallic ion present, not on the total weight of the complexes.
The novel method of the invention, i.e. the manufacture of cosmetics and toiletries with water that has first been substantially demineralized and then re~mineralized with low concentrations of desirable minerals, can be used to produce any water-based composition intended for the cleansing, moisturizing, re-mineralizing or beautification of the human body or any portion thereof, particularly the skin, scalp, hair and nails.
The novel method is simple and inexpensive to practice inasmuch as a wide variety of conventional means and instrumentation are available to accurately analyze the mineral contents of water, whereas the prior art technique of adding small amounts of desirable minerals to finished cosmetic vehicles or formulations involves analysis of compositions containing numerous organic and inorganic materials in high concentrations in addition to water.
Such analyses frequently require several steps (for example, various exkractions and precipitations) and produce results less precise than those obtained when assaying for trace minerals in purified water.
Moreovex, by the present method, the concentration of minerals in water to be used in formulating the cosmetic and toiletry products is carefully controlled from the outset to keep it in a range (from about 0.005 to about 0.2%, by weight of water) low enough not to interfere with the subsequent formulation of the products, but high enough for the henefits of the minerals to be manifested in the ~inished products.
It should also be noted that carefully controlling the upper levels of mineral concentration in cosmetic and toiletry products avoids any safety problems which might be presented iE
excessive amounts of certain minerals were incorporated into products intended for repeated application to the skin and other sensitive areas of the body.
The novel compositions containing re-mineralized water may be produced by any means known in the cosmetics and toiletries arts for formulating aqueous base products, the only exception to conventional practices being that the water to be incorporated into the novel products is first purified and demineralized and then re-mineralized in accordance with the novel method.
