Description

The present application relates to cosmetic and dermatological antiperspirant compositions which have a reduced irritation potential.

Compositions against body odor are an important part of daily personal hygiene. They should ensure that the sweat produced during the day through various activities (physical activity, work, sports) as well as psychological stress does not lead to an unpleasant body odor. Just as diverse as the components of sweat and the causes of the development of body odor are the deodorants of commercial deodorants. Suitable odor absorbers, fragrances, deodorizing ion exchangers, germ-inhibiting agents, prebiotic components and enzyme inhibitors can be used as cosmetic deodorizing agents. Body odor is, in simplified terms, due to the bacterial decomposition of the organic components of perspiration. In turn, some of the bacteria responsible for the natural microflora of human skin are responsible for bacterial degradation, especially Gram-positive anaerobic cocci, e.g. Staphylococci, such as Staphylococcus hominis, and corynebacteria. Since the body odor is caused by bacterial activity, it can be particularly effectively prevented by the use of cosmetic agents (soaps, creams, powders, sticks, rollers, gels or sprays) containing antimicrobial substances and perfume oil compositions.

As application forms for said compositions, the aerosol spray, the Rollon and antiperspirant sticks have established themselves on the market. Further, the deodorant in powder form (also called compacted powder) or the deodorant applied to a disposable substrate (such as a cloth, pad or pad) are also known. As a particularly pleasant form of application, the expert knows the so-called soft pens ("soft solids"). By viscous compositions are understood that have a creamy texture and are pushed out before use by one or more openings of a dispenser of the applicator. In this process, pressure is exerted on the composition under which the formulation often becomes unstable, thereby depositing one of its liquid components. This phenomenon is called syneresis and is usually observed with soft solids with high oil content.

In addition, the optimal release of the antiperspirant active ingredients to the site of action, especially from anhydrous cosmetic carriers out, another challenge to provide improved compositions against body odor. The expert therefore always tries to increase the release of antiperspirant active ingredients and / or the efficiency of the antiperspirant Increase active ingredients. To improve the release amphiphilic substances have been used. However, these only improve the release of the active ingredients at the site of action in the short term. Amphiphilic substances promote the incorporation of water into anhydrous compositions, which in turn causes hardening of the surface of the composition over time. This hardening results in a lack of product delivery at the site of action, which over the storage life of the anhydrous composition leads to a deterioration of the antiperspirant effect. In addition, a surface encrusted by water entry severely affects further cosmetic product properties.

To increase the efficacy of antiperspirant products, the levels of aluminum salts are often significantly increased. This practice is not only uneconomical, but can also lead to skin intolerance.

The object was therefore to provide a cosmetic composition against body odor, which has an improved efficacy of the antiperspirant active ingredients. The release of the antiperspirant active ingredients to the site of action should also be increased.

Furthermore, it was an object within the scope of the invention to provide anhydrous compositions, in particular in the form of a soft solid, which have no or at least reduced syneresis.

It has now been found that the antiplatelet effect of antiperspirant salts can be synergistically increased by a combination of certain polymers and waxes.

By virtue of the resulting pressure, said composition is forced out of said dispenser through the at least one exit orifice.

The following embodiments are intended to illustrate the subject matter of the present invention without being limited thereto.

The formulations were tested in a sauna test for their antiperspirant effectiveness. For this purpose, the products were applied on 4 consecutive days in defined areas on the back of 25 test persons. A control area opposite the respective test field remained untreated.

Twenty four hours after the last product application, perspiration was triggered in a sauna at 80 ° C for 15 minutes. Previously, absorbent pads were applied to the areas and weighed at the end of the sweat phase to determine the amount of sweat.

The table shows that the use of alkoxy-modified silicones causes an improvement in the sweat reduction (comparison V2 to V3). Formulation V1 containing only pentaerythritol distearate was only slightly better than the control (V1 to V3). If both substances are present, there is a clear increase in performance (E1 to V3), which even exceeds the additive value (expected 15.7) (measured 20.9). The inventive compositions thus show a sysnergistisch improved sweat reduction.
