Description

"Deodorants and / or antiperspirants with improved fragrance and odor absorption"

The present application relates to cosmetic and dermatological antiperspirant and deodorant compositions which have an improved scent effect and odor absorption. Commercially available antiperspirant compositions, hereinafter also referred to as antiperspirants, contain as antiperspirant active ingredient at least one water-soluble astringent inorganic and organic salts of aluminum, zinc or selected aluminum-zirconium mixed salts. Commercially available deodorant compositions, also referred to below as deodorants, often contain at least one antibacterial active ingredient as the deodorant active ingredient. The antiperspirant active ingredients have no direct influence on the activity of the sweat glands, but minimize the narrowing of the discharge channels sweat secretion. The AI salts cause sweat inhibition on the treated skin surfaces by superficial blockage of the sweat gland ducts as a result of Al-mucopolysaccharide precipitation.

Antiperspirant and deodorant compositions are usually applied and applied in the forearm region or in the region of the armpits. The skin in this area is usually more sensitive than the rest of the body's skin, often at least as sensitive as the skin on the face. There is therefore a constant need for particularly skin-compatible formulations which are suitable as carriers for cosmetic and dermatological antiperspirant and deodorant compositions. Furthermore, there is a need for particularly skin-friendly formulations which, as carriers for cosmetic and dermatological antiperspirant and deodorant compositions, may be able to make the antiperspirant and deodorant active ingredients, which irritate the skin irritating occasionally, more skin-friendly or to reduce their irritative effect ,

In addition, cosmetic products in general and deodorants or antiperspirants in particular must give the treated areas of skin a pleasant smell and neutralize any unpleasant odors that may be present. Especially when sweating high demands are placed on the funds, as they should not fail in their effect in this situation.

Object of the present invention was to provide active ingredients for cosmetic and dermatological antiperspirant and deodorant compositions with particularly high skin tolerance and to find special efficiency against odors. Another object of the present invention was to find active ingredients for cosmetic and dermatological antiperspirant and deodorant compositions, which ensure long-lasting scenting of the treated main parts and can also absorb any unpleasant odors that may be present

Surprisingly, it has been found that certain plastic particles are suitable as fragrance-fixing and long-lasting scented agents for the production of antiperspirant and deodorant compositions. In addition, these particles absorb unpleasant odors and thus further increase the performance profile of the compositions.

The plastic particles used in the present invention are described in the prior art: US Pat. No. 4,831,061 describes a porous polyamide powder having a rose flower-like structure in which the lamellae are bonded together and form cavities facing the center of the particles are aligned. The use of these particles in a variety of applications is also disclosed without further examples. European Patent Application EP 1 582 194 A1 discloses cosmetic creams containing porous polyamide particles. In the creams and decorative cosmetics disclosed therein, the particles serve to absorb excess sebum from the skin surface and thus avoid undesirable greasy shine. The production of porous polyamide particles is disclosed, for example, in Japanese Patent Laid-Open No. 2002-80629.

An object of the present application is therefore a cosmetic or dermatological deodorant or antiperspirant composition containing - in each case based on the weight of the entire composition - in a cosmetic or dermatologically acceptable carrier

at least one deodorant or antiperspirant active,

As perfume component, perfumes, perfume oils or Perfume oil ingredients are used. Perfume oils or fragrances can according to the invention individual fragrance compounds, eg.

Fragrance compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinyl acetate (DMBCA), phenylethyl acetate, benzyl acetate,

Ethylmethylphenylglycinate, allylcyclohexylpropionate, styrallylpropionate, benzylsalicylate, cyclohexylsalicylate, floramate, melusate and jasmecyclate.

Preferably, however, mixtures of different fragrances are used, which together produce an attractive fragrance. Such perfume oils may also contain natural fragrance mixtures such as are available from vegetable sources, e.g. Pine, citrus, jasmine, patchouly, rose or ylang-ylang oil.

In order to be perceptible, a fragrance must be volatile, whereby besides the nature of the functional groups and the structure of the chemical compound, the molecular weight also plays an important role. For example, most odorants have molecular weights up to about 200 daltons, while molecular weights of 300 daltons and above are more of an exception. Due to the different volatility of fragrances, the smell of a perfume or fragrance composed of several fragrances changes during evaporation, whereby the odor impressions in "top note", "middle note or body" As the smell perception is based to a large extent on the odor intensity, the top note of a perfume or fragrance consists not only of volatile compounds, while the base note for the most part from less volatile In the composition of perfumes, for example, volatile fragrances can be bound to certain fixatives, which prevents them from evaporating too quickly the smell impression and on whether the corre sponding is perceived as the head or middle note, nothing said.

The preparation of the particles can generally be accomplished by mixing a solution of polyamide in a suitable solvent and a liquid phase in which polyamides are insoluble. Usually, the liquid phase is water-based, whereby it can be achieved by suitable further solvents that when mixing the liquids first of all a clear solution is formed, from which the polyamide particles precipitate.
