Description

The present invention relates to an antiperspirant cosmetic agent without aluminum-containing compounds, which contains at least one substance selected from the group of cosmetic oils which are liquid at 20 ° C. and 1013 hPa, fragrances and waxes, and bovine serum albumin (BSA) the addition of bovine serum albumin (BSA) results in a closure of the sweat gland (s).

Furthermore, the present invention relates to the use of a combination of at least one selected from the group of cosmetic oils which are liquid at 20 ° C and 1013 hPa, fragrances and waxes, and bovine serum albumin (BSA) for reducing and / or preventing underarm sweating.

Moreover, the present invention relates to a non-therapeutic cosmetic method for preventing and / or reducing transpiration of the body, in which the antiperspirant according to the invention is applied to the skin, in particular to the skin of the armpits.

Finally, the present invention relates to the use of bovine serum albumin (BSA) for the at least partial closure of the sweat gland (s).

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).

Prior art cosmetic antiperspirants contain at least one antiperspirant salt in addition to at least one oil or fatty substance and one perfume component or perfume.

The antiperspirant salts used in antiperspirants reduce sweat secretion of the body through a temporary narrowing and / or obstruction of the excretory 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 have an additional deodorizing effect due to their antimicrobial effect.

As antiperspirant salts are usually activated basic aluminum and aluminum zirconium halides, as in the publications EP 0 308 937 A2 . EP 0 183 171 A2 . US 4,359,456 A and EP 0 191 628 described, used. Furthermore, it is also possible to use aluminum and aluminum zirconium halides which are stabilized with organic acids as complex ligands, as described, for example, in the publications US 3,542,919 A . US 3,553,316 . US Pat. No. 3,991,176 A and WO 2005/092795 A1 are disclosed.

However, the antiperspirant aluminum and aluminum zirconium halides of the prior art can cause skin irritation in people with sensitive or sensitive skin.

There is therefore a need for antiperspirant cosmetic products which, on the one hand, reduce the risk of skin irritation in sensitive skin but, on the other hand, have a satisfactory antiperspirant effect. Furthermore, the antiperspirant cosmetic agents should be inexpensive to produce.

It is an object of the present invention to provide an antiperspirant cosmetic agent which avoids or at least attenuates the disadvantages of the prior art and which has a reduced skin irritation to sensitive skin, but at the same time reliably reduces underarm wetness.

It has now surprisingly been found that the use of bovine serum albumin (BSA) in cosmetic compositions without antiperspirant aluminum-containing compounds, to a Hydrogelbildung this Means at pH values, which prevail exclusively within the excretory ducts of the sweat glands, and thus ensures an effective blockage of these ducts. Due to the selectivity of bovine serum albumin (BSA), hydrogel formation does not take place either in the antiperspirant cosmetic products or on the outside of the skin, so that the addition of bovine serum albumin (BSA) does not reduce the antiperspirant cosmetic effect due to premature hydrogel formation , Due to the omission of the use of antiperspirant aluminum-containing compounds which can cause skin irritation in sensitive skin, the antiperspirant cosmetic agents according to the invention have an improved skin tolerance to sensitive skin.
