Description

"Method for reducing sweat and / or body odor using phosphate compounds"

The present invention relates to a method of reducing transpiration of the body and / or reducing body odor caused by transpiration, in which a phosphate-containing antiperspirant cosmetic agent (M1) is applied to the human skin and remains at the site of application for at least 1 hour , This antiperspirant (M1) contains at most 1% by weight of antiperspirant aluminum and / or aluminum zirconium salts. The use of the at least one phosphate compound in the process according to the invention leads to an antiperspirant effect or to a reduction in body odor caused by perspiration.

Furthermore, the present invention relates to the use of at least one phosphate compound for reducing the transpiration of the body and / or for reducing the body odor caused by perspiration.

Washing, cleansing and caring for one's own body is a basic human need, and modern industry is constantly trying to meet these needs of man in a variety of ways. Especially important for daily hygiene is the permanent elimination or at least reduction of body odor and underarm wetness. Numerous specific deodorant or antiperspirant personal care products are known in the art which have been developed for use in body regions having a high density of sweat glands, especially in the underarm area. These are formulated in a wide variety of dosage forms, for example as powder, in stick form, as aerosol spray, pump spray, liquid and gel roll on application, cream, gel and as impregnated flexible substrates (towels).

The cosmetic antiperspirants used to reduce transpiration in prior art processes contain at least one antiperspirant compound, in particular in the form of halides and / or hydroxyhalides of aluminum and / or zirconium. These antiperspirant compounds reduce the sweat secretion of the body by temporarily narrowing and / or obstructing the ducts of the sweat glands, so that the amount of sweat can be reduced by about 20 to 60 percent. On the other hand, they prevent because of their antimicrobial effect the degradation of initially odorless sweat to malodorous compounds and thus the formation of body odor. However, the halides and / or hydroxy halides of aluminum and / or zirconium contained in the agents used can, in conjunction with the acidic pH of these agents, cause unpleasant skin reactions in some users. In addition, the use of the aforementioned antiperspirant compounds can lead to staining on clothing. There is therefore a need to replace the antiperspirant halides and / or hydroxy halides of aluminum and / or zirconium used in methods for reducing perspiration with other antiperspirant cosmetic agents. These ingredients should have a good antiperspirant effect, good skin tolerance and a simple Have formulability. In addition, these antiperspirant active ingredients should have no negative impact on the storage stability of the cosmetic products used.

The present invention has for its object to provide a method for reducing the transpiration of the body and / or to reduce the induced by the perspiration body odor, which avoids the disadvantages of the prior art or at least attenuates and which contributes to a reliable reduction of underarm wetness good skin compatibility at the same time.

It has now surprisingly been found that the use of at least one phosphate compound in cosmetic processes leads to an antiperspirant and / or odor-inhibiting effect which is almost comparable to the antiperspirant and odor-inhibiting effect of aluminum salts and / or aluminum-zirconium salts used in prior art processes is. However, no skin irritation is observed using these phosphate compounds.

The present invention thus relates to a cosmetic method for reducing the transpiration of the body and / or for reducing the body odor caused by transpiration, in which an antiperspirant cosmetic agent (M1) is applied to the human skin and remains at the site of application for at least 1 hour wherein the antiperspirant cosmetic agent (M1) in a cosmetically acceptable vehicle - based on the total weight of the cosmetic agent (M1) - a) at least one phosphate compound, and

b) contains at most 1, 0 wt .-% of antiperspirant aluminum and / or aluminum zirconium salts.

The use of phosphate-containing cosmetic agents in the method according to the invention results in an excellent reduction of perspiration, in particular axillary sweat, without causing skin irritation. Furthermore, the use of the at least one phosphate compound also a reduced formation of body odor is observed. Thus, the use of extremely small amounts or in the absence of antiperspirant halides and / or hydroxy halides of aluminum and / or zirconium, an effective reduction of armpit sweat and / or body odor is ensured. The cosmetic agents (M1) used according to the invention can be obtained by mixing the at least one phosphate compound with the at least one aluminum and / or aluminum zirconium salt.

The term "antiperspirant" is understood according to the invention to reduce or reduce the perspiration of the sweat glands of the body.

In addition, the term "fatty acids" as used in the present invention means aliphatic carboxylic acids having unbranched or branched carbon groups of 4 to 40 carbon atoms also be synthetically produced fatty acids.Furthermore, the fatty acids may be monounsaturated or polyunsaturated.

Finally, the term "fatty alcohols" in the context of the present invention means aliphatic, monohydric, primary alcohols which have unbranched or branched hydrocarbon radicals having 4 to 40 carbon atoms ,

Unless stated otherwise, the term% by weight refers in this case to the total weight of the antiperspirant cosmetic agents (M1) used according to the invention. According to the invention, the antiperspirant cosmetic agent (M1) is advantageously used to reduce transpiration in the armpit and / or to reduce underarm odor. Preferred methods according to the invention are therefore characterized in that the antiperspirant cosmetic agent (M1) is applied to the skin of the armpit.

1 . In vivo test for antiperspirant activity

To determine the antiperspirant effect, an antiperspirant study was carried out on the backs of 16 test persons. The following antiperspirants were used for this:

* Active ingredient

** according to the invention

^a) sodium pyrophosphate of formula ΝΒΣΗΣΡΣΟ and / or sodium hydrogen phosphate of the formula NaH ₂ P0 ₄

On the back of 16 test persons, 40 μl of the antiperspirant agent V-1 and 75 μl of the cosmetic compositions E-1 and E-11 were each applied to one side of the backbone. After 5 minutes, the treated sites were covered with occlusive non-adsorbent film. After 2 hours, these non-absorbent pads were removed. The compositions were each applied to the back of the subjects for four consecutive days in the manner previously described. 24 hours after the last application of the composition, absorbent pads were applied to the backs of the subjects at the points where the compositions were previously applied. Furthermore, on the other side of the spine at the same height also pads were applied, which served as a control. After sweating for about 15 minutes at 80 ° C in the sauna, the amount of perspiration absorbed by the pads was determined gravimetrically, comparing each composition with the corresponding untreated spot on the back. From the gravimetric determination of the amount of sweat, the sweat reduction was determined, with all the values determined were statistically significant.

The sweat reduction of the respective composition in comparison to an untreated skin site is shown in the following table:

The use of cosmetic products containing specific phosphate compounds, when applied to the skin, results in a reduction of transpiration and reduced body odor.
