DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a cosmetic composition, particularly for decorative applications. Decorative cosmetics mostly involve carrier materials compounded with dyes or pigments which are intended to place coloured accents in the wearers' faces, on their hairstyle, etc. Typical decorative cosmetics products are nail polishes, eye shadows, lipsticks, powders--both for the face and the body--hair sprays, and the like. Recently allergic reactions have occurred to the wearers to a very high degree in relation to such compositions, particularly when dyes or carrier materials are used which are suited to act as nutrient media for bacteria and colonization of micro-organisms or which may age due to simple chemical decomposition, e.g. under the effects of light, when the products are allowed to stand for an extended period of time, thus producing decomposition products which may cause allergies.
Another disadvantage of known decorative cosmetic products is their only very restricted period of usefulness and their frequent sensitivity to temperature; this is the reason why storage in specialized cosmetics shops is not unproblematic.
Extensive tests on animals even are not suited to predict undubitably such allergic reactions as those which may be caused particularly by decomposition arising from extended or inadequate storage.
Moreover, there is an ever-increasing demand for particularly lustrous reflecting cosmetic colours for evening events or for the makeup of actors, with the demands to luster and high reflectivity not being satisifed in this field by the common organic dyes or even the normal inorganic minerals.
The problem underlying the present invention is thus the provision of an improved cosmetic composition which will employ dyes which are better to tolerate and afford better optical effects.
According to the present invention, this problem is solved by a composition comprising a liquid, highly viscous or a solid, dermatologically compatible carrier material and a pure powder of precious stones or mixtures of precious stones. If necessary, incinerated precious stones may be used.
The composition may, of course, contain a perfume component as usual in cosmetics.
In a preferred embodiment precious stone powder is added into a carrier liquid in which it is emulsified or emulsifiable, if necessary by means of the addition of emulsion stabilizers. Such liquids are suitable, for instance, for liquid eye shadows, liquid lip gloss, nail polishes and the like.
It has proven to be expedient for other preferred applications to use the inventive composition in a highly viscous salve-like carrier material desirable for applications such as creamy eye shadows, soft lipsticks, creamy lip gloss and similar products. It turned out that eucerine or VASELINE.RTM. are specifically well suited as stable carrier materials.
Silicic acid may also be added as an additional auxiliary product.
Another preferred embodiment of the inventive composition is a mixture of precious stone powder with powder bases known per se, such as powdered soapstone or talcum powder. These powders may be used as lustrous makeup or lustrous talcum powder either in a loose or cake form.
The inventive decorative compositions contain the precious stone powder in quantities by up to 10% in weight, preferably by roughly 5% by weight. Depending on the respective application, however, the quantity may also be increased or reduced.
Due to purely mineral crystallized compounds being used as dyes, which are moreover very hard and, due to the missing surface pores, are not suited to form nutrient media for bacteria allergic reactions to these coloring materials may practically be precluded.
Earth or mineral colors such as clays, which have so far been used, are a really ideal nutrient medium for bacteria due to their porous surface.
But organic dyes, too, which are used, for instance, in combination with metal powders for eye shadows, have frequently resulted in allergic reactions to the dyes themselves or to by-products of reactions, which adhered to the
