Antiperspirant wipes

The present invention relates to cosmetic or dermatological antiperspirant wipes.

Body odors in their original sense are used for social communication. For example, special substances (pheromones) secreted by the scent glands have a significant influence on sexual, territorial and aggressive behavior in the animal world or are an expression of individuality or ranking. However, this type of communication has lost much of its importance for humans, as the comparatively poor performance of the human sense of smell indicates. Body odor is seen in modern western societies as obtrusive, repulsive and neglected. The use of cosmetic or dermatological deodorants / antiperspirants offers a way to counteract unpleasant body odor.

Body odor arises when the odorless fresh sweat is broken down by microorganisms. The gram-positive bacteria break down the sebum, protein substances and the dissolved components of the sweat. This frees up odor-intensive short-chain fatty acids and amines. Apocrine sweat, in particular, transports a series of microorganisms to the surface of the skin via the sebaceous glands and hair follicles, which very soon intervene in the decomposition. However, there is also a certain resident microorganism population on the skin, which, supplemented by transient microorganisms from the environment, influences the breakdown of sweat.

The usual cosmetic deodorants and / or antiperspirants are based on different active principles. The usual active ingredients used in deodorants and / or antiperspirants, for example, have antimicrobial properties that prevent the microbial decomposition of fresh sweat. A deodorizing effect can also be achieved by enzyme-inhibiting but not antimicrobial substances and / or by ion exchangers. Cation exchanger z. B. are said to absorb ammonia, indole and similar odors. Active ingredients with antiperspirant properties, on the other hand, are those that reduce or completely suppress sweating in the human body, the effect being topical when applied topically. The effectiveness of deodorant or antiperspirant active ingredients also depends, among other things, on the formulation base into which they are incorporated and on the auxiliaries and / or additives used in the production.

The active substances used in so-called antiperspirants primarily inhibit sweat secretion, but generally also have a certain antibacterial effect. They have a blocking effect on the part of the execution duct of the sweat glands that leads through the stratum corneum. They constrict or close the sweat glands so that sweating is completely or partially suppressed.

Antiperspirants are used primarily in the form of aqueous solutions and as powders or granules (dry sprays). Other forms of preparation, such as. B. alcoholic solutions, emulsions, creams, ointments and the like are possible in principle, but sometimes difficult to formulate stable.

A relatively new technical development are also microemulsions with a significant content of antiperspirant active ingredients such as aluminum chloride, aluminum chlorohydrate and / or aluminum zirconium salts. Such formulations are commercially available, for example, in the form of pump sprays.

Antiperspirants and / or deodorants are offered in different forms of application, e.g. B. as aerosols, pump sprays, rollers or pens, which naturally differ greatly in their composition. However, due to the ongoing discussion about the disadvantages of aerosol applications, the development of antiperspirants and / or deodorants today focuses on gels, pump sprays, rollers and pens.

Commercial antiperspirants reduce sweat by 20 to 60%. The rule here is that the effectiveness increases the higher the active substance concentration. Cosmetic or dermatological antiperspirants generally contain the active ingredient (s) in a concentration of 10 to 15% by weight, depending on the desired sweat reduction up to 20% by weight or more.

An important quality feature of antiperspirant products is the feeling on the skin that arises after the application under the armpits. The aluminum compounds known as antiperspirant agents, when used in the form of cosmetic or dermatological preparations, tend to cause a sticky feeling after application to the skin and drying or drawing in of the formulations, which in individual cases can lead to the products not being marketable because they are not accepted by consumers or judged negatively. The higher the active substance concentration, the greater the problem.

This disadvantage of antiperspirant products has been known for some time, and solutions have already been described several times in the patent literature (e.g. in EP 084911 A3, DE 26 35 956 C2, DE 33 10 958 C2, US 4,053,581, US 4,065,564 and US 4,073,880). A number of substances can therefore be added to the antiperspirant products corresponding to the prior art, which are intended to reduce the sticky feeling on the skin. These are usually PPG-15 stearyl ethers, polyglycols or volatile or non-volatile silicone compounds and the like.

Antiperspirant wipes are also known per se. For example, B. the British patent application GB 2 110 928 A, the combination of antiperspirant cosmetic tissues and corresponding sealed packaging, the antiperspirant preparation consisting of a 25% solution of aluminum chloride and 3% Hydagen deodorant in an ethanolic base. However, this document could not show the way to the present invention. According to the above, the customary commercially available antiperspirant products are generally distinguished by the fact that the cosmetic or dermatological preparation does not come into contact with the hands of the user.

However, in order to apply an antiperspirant active ingredient with the aid of a cloth, the consumer must take the cloth in his hand, whereby he comes into contact with the soaking solution. The skin feel caused by product residues on the hands is therefore crucial for the product quality of antiperspirant wipes. Special attention must be paid to this problem when formulating such products, since the majority of consumers perceive product residues as very unpleasant, especially on the hands, since the hands are extremely sensitive to touch. There is almost always a need to clean your hands.

Surprisingly, however, the use of the state-of-the-art tack-reducing agents in antiperspirant wipes does not lead to the desired success. Apparently, the properties of substances that prevent sticking under the armpits cannot be transferred to antiperspirant wipes, in which the formulation also comes into contact with the hand.

The object of the invention was therefore to remedy the disadvantages of the prior art and to find antiperspirant impregnation solutions and / or antiperspirant wipes which have a good effect, have good skin compatibility and do not leave or leave a sticky feeling on the skin and in particular on the hands . cause.

Another object of the present invention was to develop preparations which are suitable as a basis for cosmetic or dermatological antiperspirant wipes and which are distinguished by good skin tolerance.

It was surprising, however, and in no way predictable to those skilled in the art, that antiperspirant wipes included a carrier material made of woven and / or non-woven, flexible material which is impregnated with a microemulsion, the microemulsion, based in each case on the total weight of the microemulsion, (a) 0.3 to 2.5% by weight of one or more Glyceryl esters, (b) 0.1 to 1% by weight of one or more alkyl alcohols,

(c) 0.5 to 5% by weight of one or more alkyl alcohol polyethylene glycol ethers and

(d) contains at least 4% by weight of one or more antiperspirant active ingredients, the total content of the substances according to (a), (b) and (c) being at least 2% by weight remedy the disadvantages of the prior art.

Carrier materials preferred according to the invention are dry cloths which are constructed, for example, from materials such as paper and / or a wide variety of mixtures of natural or synthetic fibers. Such cloths can possibly be embossed advantageously (macroscopically).

Advantageous wipes exist e.g. B. from water jet consolidated and / or water jet embossed nonwovens (spunlaced material). If the nonwovens have embossments in the sense of the present invention, they can have any desired pattern. The selection to be made depends on the one hand on the impregnation to be applied and on the other hand on the special field of application in which the subsequent cloth is to be used.

Large cavities on the surface of the cloth and in the cloth make it easier for dirt and impurities to be absorbed if the impregnated cloth is run over the skin. The cleaning effect is increased many times compared to non-embossed wipes.

Woven cloths and papers are also advantageous carrier materials for the purposes of the present invention.

Advantageous wipes in the sense of the present invention have a tear strength of in particular
