Description

The invention relates to anhydrous compositions which contain, in addition to an antiperspirant active ingredient, an emulsifier sorbed on silica particles.

Washing, cleansing and caring for the human body is an important basic need, and cosmetic manufacturers are always trying to meet the ever-changing and evolving needs of consumers by providing novel and / or improved products. A fundamental component of daily hygiene is, for example, the effective elimination or at least the significant reduction of body and / or sweat odor. These odors are caused by the bacterial decomposition of various constituents of human (apocrine) sweat on the skin, among other things, lower fatty acids (especially C _4-10 fatty acids), ammonia, amines, indoles and sulfur-containing substances. To combat body odor and / or odor, products are offered in a variety of dosage forms, such as powders, pens, aerosol sprays, pump sprays, liquid and gel-like roll-ons, creams, gels and impregnated flexible substrates (so-called deodorant towels).

Cosmetic antiperspirants usually contain at least one antiperspirant salt in addition to at least one oil or a fatty substance and a fragrance component or a perfume. When used regularly, antiperspirants often leave (white to yellow) residues on the skin and on clothing. This leads to unwanted staining on textiles (antiperspirant (AT) stains), which can not be removed by conventional washing procedures without thorough and time-consuming pretreatment. The staining is based on a complex interaction of prescription constituents of the antiperspirant, sweat and the detergent used. In order to avoid (white to yellow) residues on the skin and / or on textiles, antiperspirants have in the past been added to hydrophobic non-volatile oils as masking agents. However, oils are also difficult to remove from textiles and, in extreme cases, can even intensify AT stains. In order to protect textiles against such permanent soiling, various ingredients, especially surfactants, are usually used in antiperspirants.

In WO 2013 / 096351A1 Antiperspirants have been proposed which contain sorbed surfactants on the surface of silica particles. The surfactants can be released during the washing process and contribute to the removal of the aforementioned stains.

In the formulation of anhydrous antiperspirants were those in the o.g. However, the proposed compositions are unsatisfactory. In particular, in the preferred case where anhydrous antiperspirants include as masking agents ester oils, nonvolatile silicone oils and / or alkyl ethers, AT stains could not always be completely removed in normal and low temperature washing.

The present invention was therefore based on the object to eliminate the aforementioned disadvantages of the prior art and to provide very good sweat and odor reducing, anhydrous, storage-stable antiperspirants available, which reduce and / or prevent textile discoloration and / or textile stains of any kind. In particular, by the use of anhydrous antiperspirants (which contain non-volatile oils such as ester oils as masking agents) resulting AT oil stains on textiles should be prevented and / or reduced. In addition, the antiperspirants should preferably be suitable for use as an aerosol and have very good spray properties.

It has now surprisingly been found that certain nonionic emulsifiers sorbed on silica significantly reduce antiperspirant stains - especially oil-based or oil-enhanced AT stains - without adversely affecting the antiperspirant effect and storage stability of the antiperspirants. The targeted choice of emulsifiers in certain amounts, the skin compatibility of the compositions could be further increased and lowered the irritation potential (compared to previously described, earlier antiperspirants).

• a) mindestens einen Antitranspirant-Wirkstoff und
• b) mindestens einen an Kieselsäurepartikel (Silica) sorbierten Emulgator enthält, wobei der mindestens eine Emulgator einen HLB-Wert < 11 aufweist.

A first object of the present invention is therefore an anhydrous composition which

• a) at least one antiperspirant active substance and
• b) contains at least one adsorbed on silica particles (silica) emulsifier, wherein the at least one emulsifier has an HLB value <11.

The term "anhydrous" according to the invention is understood to mean that the compositions contain 0 to a maximum of 3 wt .-%, preferably 0 to a maximum of 2 wt .-% and in particular 0 to 1 wt .-%, free water, based on the total weight of Composition. The content of water of crystallization, water of hydration or similar molecularly bound water which may be contained in the constituents used, in particular in antiperspirant active ingredient (combinations), does not constitute free water in the sense of the present application.

For the purposes of the present invention, the term "sorbed" is understood to mean the absorption of a substance into the volume of a body (absorption) or the occupation of a solid surface with a thin molecule layer by adhesion (adsorption). In other words, the emulsifier can be absorbed into the silica particles or adsorbed on the silica particles.

As the first essential component, the compositions according to the invention contain at least one antiperspirant antiperspirant active substance a).

According to the invention preferred antiperspirant antiperspirant active ingredients a) are water-soluble astringent inorganic and organic salts of aluminum, zirconium and zinc or any mixtures of these salts. Particularly preferred antiperspirant active ingredients are selected from aluminum chlorohydrates, for example aluminum sesquichlorohydrate, aluminum chlorohydrex-propylene glycol (PG) or polyethylene glycol (PEG), aluminum sesquichlorohydrex PG or PEG, aluminum PG-dichlorhydrex or aluminum PEG-dichlorhydrex, aluminum hydroxide from Aluminiumzirconiumchlorhydraten as Aluminiumzirconiumtrichlorhydrat, Aluminiumzirconiumtetrachlorhydrat, Aluminiumzirconiumpentachlorhydrat, Aluminiumzirconiumoctachlorhydrat, aluminum-zirconium chlorohydrate glycine complexes, such as Aluminiumzirconiumtrichlorhydrexglycin, Aluminiumzirconiumtetrachlorhydrexglycin, Aluminiumzirconiumpentachlorhydrexglycin, Aluminiumzirconiumoctachlorhydrexglycin, potassium aluminum sulfate ((KAl SO _{4) 2} · 12 H ₂ O, alum), Aluminiumundecylenoylkollagenaminosäure, Sodium aluminum lactate + aluminum sulfate, sodium aluminum chlorhydroxactate, aluminum bromohydrate, aluminum chloride, from complexes of zinc and sodium rium salts, the complexes of lanthanum and cerium, the aluminum salts of lipoamino acids, aluminum sulfate, aluminum lactate, aluminum chlorohydroxantoinate, sodium aluminum chlorhydroxylactate, zinc chloride, zinc sulfocarbolate, zinc sulfate and zirconium chlorohydrate.

By "water-solubility" is meant according to the invention a solubility of at least 5 wt .-% in water at 20 ° C, that is, that amounts of at least 5 g of the antiperspirant active in 95 g of water at 20 ° C are soluble. The antiperspirant active ingredients can be used as aqueous solutions.

Particularly preferred compositions according to the invention are characterized in that they contain as antiperspirant active substance a) preferably an astringent aluminum salt, in particular aluminum chlorohydrate, aluminum quin chlorohydrate and / or aluminum chloride, in a total amount of 5-60% by weight, preferably 10-50% by weight. -% and in particular 15-40 wt .-%, wherein the amounts are based on the total weight of the compositions.

A first preferred embodiment is characterized in that the anhydrous compositions according to the invention comprise at least one antiperspirant active substance a) selected from astringent aluminum salts, preferably aluminum chlorohydrate, aluminum sesquichlorohydrate and / or aluminum chloride, in a proportion by weight of the total weight of the composition of 5 to 60% by weight. %, preferably from 10 to 50 wt .-% and in particular from 15 to 40 wt .-%, contained.

As a second essential ingredient, the compositions according to the invention contain at least one emulsifier b) sorbed on silica particles (silica) and having an HLB value <11.

It has been found that nonionic emulsifiers of HLB <11 are particularly well suited for sorbing to specific silica particles and effective in anhydrous antiperspirants, especially in anhydrous antiperspirants containing ester oils, non-volatile silicone oils and / or alkyl ethers as sequestering agents contribute to AT-stain reduction and / or avoidance. Such modified silica particles b) are suspended together with the antiperspirant active in a carrier oil. After application of the antiperspirant composition, part of the formulation is transferred to body-worn textiles, with the silica particles loaded with the non-ionic emulsifier also reaching the textile. In the washing process (even at low washing temperatures up to about 40 ° C), the nonionic emulsifier is released from the surface of the silica particles, which locally a high emulsifier concentration is achieved. Due to the specific selection of nonionic emulsifiers of an HLB Range <11 achieves a particularly good emulsification and thus removal of oil components from textiles - in particular ester oils, nonvolatile silicone oils and / or alkyl ethers.

In a second particularly preferred embodiment, the at least one emulsifier is nonionic.

In a third preferred embodiment, the at least one - preferably nonionic - emulsifier preferably has an HLB value of from 1 to 10, particularly preferably from 2 to 10, very particularly preferably from 3 to 10 and in particular from 4 to 10.

The compositions of the abovementioned tables can be filled and sprayed in a weight ratio (1: 4), for example, with the propellant propane / butane (15/85) in commercially available aerosol cans. It has been found that the spray properties of compositions according to the invention which are formulated as aerosols are particularly good if they comprise at least one of the abovementioned ester oils, more preferably a mixture of isopropyl myristate and triethyl citrate.

II. Proofs of Effect

For the preparation of the loaded silica particles per 30 g of the respective emulsifier with 30 g was mixed ethanol and stirring at 35 ° C to 40 g of the thickening silica having the trade designation Sipernat ^® 50 S (INCI: Hydrated Silica, Evonik Degussa) was added. It was further stirred until complete absorption of the liquid phase. To prepare the antiperspirant suspensions, all components of the following table were mixed at 30 ° C and homogenized. The compositions thus obtained can be filled, for example, in a weight ratio (1: 4) with the propellant propane / butane (15/85) in aerosol cans.

To assess the staining, equal amounts of the eight formulations of the following table (E1-E4: compositions according to the invention, V1, V2: comparison compositions, K1, K2: control compositions) were applied without propellant to identical, white cotton textiles. Subsequently, each cotton fabric was incubated with an electrolytic solution for 60 minutes, washed at 40 ° C in a commercial washing machine with a defined soil load, dried and ironed. This process was repeated a total of four times. By colorimetric measurement (Minolta / Konica, type CR400), the delta b * value was determined as a measure of the yellow staining. The following table shows the reduction of the yellow staining after application of the compositions E1 to E4 of the invention over the control compositions K1 and K2. The table also shows that the reduction in staining was significantly lower for Comparative Compositions V1 and V2.
