DESCRIPTION:
BRIEF SUMMARY
The invention relates to the use of flower wax in liquid hair treatment agents, as well as liquid hair treatment agents containing flower wax.
It is commonly known that natural plant waxes such as carnauba wax or candelilla wax have already found multiple uses in cosmetic preparations. From the published international patent application WO 93/17083 the use of apple wax for the production of cosmetic conditioning and cleansing agents for skin and hair is already known. The valuable properties of these already carefully researched natural plant waxes have in the meantime led to the development of modern extraction methods allowing for a good yield of isolated plant waxes free of interfering impurities.
While essential oils that can be isolated from natural flowers have received a particularly strong interest for the production of fragrances and perfumes, the waxes that can be isolated from natural flowers have found only little attention until now. More in-depth research has shown, however, that waxes isolated from natural flowers combine a plurality of valuable properties that could lead to expectations of increased future commercial significance for these type of waxes.
Similar to all natural plant waxes, flower waxes also distinguish themselves by having hydrophobic properties, such as melting and emulsifying properties and biodegradability. Particularly with flower wax these properties are now additionally combined with technically applied parameters which provide good prerequisites for use in hair treatment agents.
In the Japanese published patent application 21 608 of 1984 main treatment products (cream, lipstick) and a solid hair stick are described as containing jasmine flower wax. Liquid hair treatment agents have not been mentioned.
The subject of the invention is therefore a liquid hair treatment agent containing a wax isolated from natural flowers. Particularly the wax of such flowers as jasmine (Jasminum officinale), mimosa (Mimosa pudica), narcissus (Narcissus sp.), bitter orange (Ponciurus trifoliata) and wild camomile (Matricaria chamomilla) have already been closely researched and have demonstrated remarkable and valuable properties.
Noticeable in such preparations is the high absorption rate into the hair. Even minimal concentrations already have a marked conditioning effect on the hair. In addition, a significant luster and a marked neutralization of worked-in fragrances can be noticed in the cosmetic hair preparations. In addition, a liquid hair treatment agent containing flower wax is distinguished by its dermatological compatibility, its good moisturizing capacity and its oil-restoring effect, e.g. in hair cleansing lotions. These effects are achieved when the liquid hair treatment agent has a flower wax content in a quantity of 0.001 to 20 weight-percent, preferably in a quantity of 0.01 to 12 weight-percent, and particularly preferably in a quantity of 0.03 to 2 weight-percent. Flower waxes are therefore particularly applicable for the use of hair conditioners, shampoos, styling preparations, hair treatment agents made of foam, hair coloring agents, hair sprays and hair lotions. In this case the flower waxes are used in combination with all conventional cosmetic raw ingredients for liquid hair treatment agents, with the exception, however, of strongly oxidizing substances such as hydrogen peroxide. The liquid hair treatment agents can particularly be in the form of a solution, a water-in-oil or oil-in-water (w/o or o/w) emulsion, or a liquid gel or foam.
Proof of the characteristic absorption rate of the flower wax leading to the protective and conditioning effect of the hair can clearly be demonstrated by means of x-ray photoelectron spectroscopy (XPS). This is a surface sensitive measuring technology which makes it possible to determine the composition of elements and the compound condition of the elements in the outer-most molecular layer (information depth a few nanometers).
