    专利说明:

    The present invention relates to an antiperspirant cosmetic agent, which comprises, in an aqueous cosmetic vehicle, at least one branched homopolyethyleneimine (also sometimes called “PEI” below) which is present with selected anions, the cosmetic agent having a acidic or neutral pH. The use of a cosmetic agent containing said PEI allows the preparation of antiperspirant cosmetic agents, which do not contain aluminum and / or zirconium salts but are very effective and form less stains on textiles.
    Furthermore, the present invention relates to a non-therapeutic cosmetic method intended to prevent and / or reduce body sweating, in which an antiperspirant cosmetic agent according to the invention is applied to the skin, in particular on the skin of the armpits, and remains there. for at least 1 hour, preferably for at least 2 hours, more preferably for at least 4 hours, in particular for at least 6 hours.
    Washing, cleaning and taking care of one's own body is a primary human need, and modern industry is constantly trying to meet these human needs in a variety of ways. The permanent elimination or at least the reduction of body odors and underarm sweat are particularly important for daily hygiene. Many specific deodorant or antiperspirant body care products are known in the prior art, which products have been developed for use in areas of the body having a high density of sweat glands, particularly in the armpit area. These are formulated in a wide variety of administration forms, for example in the form of powder, stick, aerosol spray, pump spray, ball application of a liquid or gel product, cream, gel and flexible impregnated substrates (deodorant wipes).
    The cosmetic antiperspirants of the prior art contain, in addition to at least one oil or a wax and an odoriferous component or a perfume, at least one antiperspirant compound in the form of aluminum salts and / or aluminum-zirconium, in in particular in the form of aluminum halides and / or hydroxyhalides and / or zirconium. These antiperspirant compounds reduce, on the one hand, the sweat secretion of the organism by temporarily shrinking and / or by obstructing the excretory channels of the sweat glands, so that it is possible to reduce the amount of perspiration by approximately 20 to 60%. On the other hand, they have an additional deodorant effect due to their antimicrobial action.
    Aluminum and / or zirconium halides and / or hydroxyhalides, combined with the acidic pH of these antiperspirants, can cause unpleasant skin reactions in some users. In addition, the use of the above-mentioned antiperspirant compounds can cause staining on clothing.
    Patent WO 2006/018073 A1 describes various polyamines, including polyethyleneimines, serving as alternatives to aluminum halides and / or hydroxyhalides and / or zirconium as antiperspirants. These antiperspirants are described in patent WO 2006/018073 A1 as a flocculant, which means that the transmission of natural perspiration by light is reduced by at least 10% on contact with the antiperspirant agent. Patent WO 2006/018073 A1 further reveals that the water-soluble flocculating polymers are present in partially or fully quaternized form at a pH of 4 to 8. It is assumed that the antiperspirant effect is based on the fact that the excretory channels sweat glands are blocked by the flocculants formed. The formation of flocculants is often perceived by consumers as visually unpleasant, and flocculants can also end up on clothing and leave stains on it.
    The object of the present invention is to prepare antiperspirants without halide and / or hydroxyhalide of aluminum and / or zirconium. The antiperspirant active ingredients present in the cosmetic agent must have an improved or very good antiperspirant effect and leave fewer stains on textiles.
    It was surprisingly discovered that the use of certain polyethyleneimines, which are present in a cosmetic agent, the pH of which may be acidic or neutral, and containing certain anions, have an antiperspirant effect which is even comparable to that of formulations containing aluminum and / or aluminum-zirconium salts. Consequently, the antiperspirants according to the invention do not contain aluminum halides and / or hydroxyhalides and / or antiperspirant zirconium.

    By the term "antiperspirant" is meant according to the invention the reduction or reduction in the sweating of the sweat glands of the body.
    The term “halides and / or hydroxyhalides of aluminum and / or zirconium” is understood within the context of the present invention, in particular the chlorides, bromides and iodides of aluminum and zirconium and the compounds of formulas AI (OH) y X and Zr (OH) z X, X representing a halide ion in the formulas mentioned above. The fact that the cosmetic agent does not contain aluminum halides and / or hydroxyhalides and / or zirconium according to the invention means that their content is less than 0.5% by weight, preferably less than 0 , 1% by weight, particularly preferably equal to 0% by weight.
    Unless otherwise indicated, the mass percentages indicated in the present invention relate to the total amount of the cosmetic agent, in the absence of any propellant.
    The essential for the present invention is the presence of at least one branched homopolyethyleneimine ("PEI"). Homopolyethyleneimines are generally composed of the following structural units and can be linear or branched.
    The branched polyethyleneimines can be described by the following partial schematic structural formula, that is to say by a part of the overall structure without the representation of the ends, and can have different ratios of primary, secondary and tertiary amino groups.
    Polyethyleneimines can also be branched into a star shape.
    Branched and unbranched homopolyethyleneimines have an alkaline pH in an aqueous solution. In the acid pH range, the quaternizable amino groups are present in partially to fully quaternized form.
    It has been surprisingly found, in the context of the present invention, that certain branched homopolyethyleneimines in a range from acidic to neutral pH and combined with certain anions, in particular chloride ions, exhibit an excellent antiperspirant effect. In particular, when an acidic pH has been obtained using hydrochloric acid, so that the chloride ions are present in the form of anions, an excellent antiperspirant effect has been observed. Even at low concentrations of said PEI, ie around 3% by weight, an antiperspirant effect comparable to that of a 10% by weight aluminum chlorohydrate solution could be produced.
    The homopolyethyleneimines used according to the invention are branched polyethyleneimines which are not modified, that is to say which have no substituents on the nitrogen atoms apart from the hydrogen radicals. According to the invention, homopolyethyleneimines are also understood to mean that these are composed only of ethyleneimine as a structural unit and do not have other monomers, such as, for example, d other alkylene imine units.
    As mentioned above, branched homopolyethyleneimines may have different ratios of primary, secondary and tertiary amino groups. The homopolyethyleneimines used according to the invention are those which, in an alkaline pH range, have a proportion of tertiary amino groups from 20 mol% to 35 mol% relative to the total amount of amino groups of the homopolyethylene imine. Since the homopolyethyleneimines are present according to the invention in a range of acidic pH, the quaternizable amino groups are partially or completely quaternized. Consequently, in the present invention, the proportion of tertiary amino groups is not defined in homopolyethyleneimine, but it is the proportion of amino groups having three radicals without hydrogen atom which is defined up to 20 mole% to 35 mole% in homopolyethyleneimine, relative to the molar amount of all the amino groups, therefore quaternary and non-quaternary amino groups, (i.e. relative to the sum of all groups containing one, two or three radicals without a hydrogen atom). The proportion of amino groups having three radicals without hydrogen atom is, according to the invention, preferably from 21 to 32 mol%, more preferably from 22 to 30 mol%, relative to the molar amount of all amino groups in homopolyethyleneimine respectively.
    The proportion of amino groups comprising a radical other than hydrogen (corresponding to primary amino groups at an alkaline pH) is, according to the invention, preferably from 30 to 45 mol%, more preferably from 35 to 42 mole%, based on the molar amount of all amino groups in homopolyethyleneimine respectively.
    The proportion of amino groups comprising two radicals other than hydrogen (corresponding to secondary amino groups at an alkaline pH) is, according to the invention, preferably from 30 to 45 mol%, more preferably from 32 to 40 mol%, more preferably 34 to 38 mol%, based on the molar amount of all amino groups in the homopolyethyleneimine respectively.
    In particularly preferred cosmetic agents according to the invention, the proportion of amino groups comprising a radical other than hydrogen (corresponding to primary amino groups at an alkaline pH) is from 35 to 42 mol%, the proportion of amino groups comprising two radicals other than hydrogen (corresponding to secondary amino groups at an alkaline pH) is from 34 to 38 mol% and the proportion of amino groups comprising three radicals other than hydrogen is from 22 to 30 mol% , based on the molar amount of all amino groups in the homopolyethyleneimine respectively.
    The proportion of primary, secondary and tertiary amino groups, relative to the molar amount of all amino groups in homopolyethyleneimine, can be determined by NMR spectroscopy.
    It is essential for the present invention that the cosmetic agent has an acidic pH, ranging from 2.5 to 7.5 (determined at 22 ° C). The pH of the cosmetic agent according to the invention is preferably defined in a range from 2.5 to 7.0, more preferably from 3.0 to 5.5, even more preferably from 3.3 at
    4.5. As already mentioned, the aqueous solutions of unmodified homopolyethyleneimines have an alkaline pH. A pH adjusting agent is used to bring the pH value within the range claimed by the invention. According to the invention, inorganic acids such as hydrochloric acid, phosphoric acid and / or sulfuric acid are particularly suitable for this purpose. The inorganic anions contained in the cosmetic agent according to the invention are therefore chloride ions, sulfate ions and / or phosphate ions, chloride ions being particularly preferred. It is with chloride ions that the best antiperspirant effect has been observed. In preferred embodiments, the chloride is therefore present as an inorganic anion. The proportion of chloride ions is preferably 10%, 30%, 50%, 95.0% by weight or more, more preferably 99.0% by weight to 100% by weight, of all anions present. According to the invention, the hydrogen sulfates also form part of the sulfate ions. Hydrogenophosphates and dihydrogenophosphates also count among the phosphates according to the invention
    In embodiments of the invention, at least one other anion may be present in addition to the chloride, sulfate ions and / or phosphate ions. Other anions present can be inorganic or organic anions. The organic anions can be, for example, phosphonates, citrate, lactate, tartrate and / or malate. It has been found in the context of the present invention, that with the exclusive use of organic anions such as lactate and / or citrate, the antiperspirant effect obtained was zero or only weak. In preferred embodiments, the cosmetic agents therefore contain lactate and / or citrate in a total amount of less than 0.5% by weight, preferably less than or equal to 0.1% by weight, more preferably equal at 0% by weight, relative to the total amount of the cosmetic agent.
    In preferred embodiments of the invention, no other anion is present except for chloride ions, sulfate ions and / or phosphate ions.
    According to the invention, the homopolyethyleneimines contained in the cosmetic agent have an average molar mass Mw of 300 to 10,000 g / mol, preferably from 500 to 3,000 g / mol, more preferably from 1,000 to 2 000 g / mol. The average molar mass Mw can be determined, for example, by gel permeation chromatography (GPC) (Andrews P: "Estimation of the Molecular Weights of Proteins by Sephadex Gel-Filtration"; Biochem. J., 1964, 91, pages 222 to 233).
    The cosmetic agent according to the invention contains at least one homopolyethyleneimine in a total amount of 0.1 to 20% by weight, based on the total amount of the cosmetic agent. The at least one homopolyethyleneimine is preferably present in a total amount of from 0.5 to 10% by weight, more preferably from 2.0 to 7.0% by weight, even more preferably from 2.5 to 5.0% by weight. Due to the excellent antiperspirant effect of homopolyethyleneimine in an acid pH range in the form of chloride, sulfate and / or phosphate, in particular in the form of chloride, it is possible to obtain an excellent antiperspirant power even with concentrations of relatively low usage.
    The antiperspirant effect is based on exerting an influence on the sweat gland (s). To exert an influence on the sweat gland (s) means, according to the invention, to exert an influence in the sense of an inhibition or reduction of sweat excretion by the excretory canal.
    The cosmetic agent according to the invention consequently contains at least one emulsifier. The cosmetic agent according to the present invention can be formulated in the form of an oil-in-water emulsion or in the form of an oil-in-oil emulsion. In the context of the present invention, it is preferable that the antiperspirant cosmetic agent is present in the form of an oil-in-water emulsion. In this case, the cosmetic agent according to the invention is preferably sprayed in the form of a pump spray without a propellant or a pressure sprayer, or applied in the form of a ball applicator. In the context of the present invention, it is preferable that the antiperspirant cosmetic agent is present in the form of a water-in-oil emulsion. It may in particular be a sprayable water-in-oil emulsion, capable of being sprayed by means of a propellant.
    The antiperspirant cosmetic agent according to the present invention may be in the form of an aqueous, hydroalcoholic or hydroglycolic solution and / or emulsion. The cosmetic agent can be in a fluid form or in the form of a product having an adjusted viscosity (flow behavior).
    The at least one emulsifier is present in a total amount of from 0.05 to 10.0% by weight, preferably from 0.2 to 5.0% by weight, more preferably from 1.0 to 4.0 % by weight, more preferably 1.5 to 3.0% by weight.
    The emulsifiers suitable according to the invention can be chosen from anionic, cationic, nonionic, amphoteric, especially ampholytic and zwitterionic emulsifiers. However, as homopolyethyleneimine is present, according to the invention, with certain anions, in particular chloride, nonionic emulsifiers are particularly preferred according to the invention. In preferred embodiments, the cosmetic agent according to the invention contains only nonionic emulsifiers.
    Oil-in-water emulsifiers:
    The cosmetic agents according to the invention, which are formulated in the form of an emulsion, in particular an oil-in-water emulsion, preferably contain at least one non-oil-in-water emulsifier. ionic having an HLB value greater than 7 and going up to 20. These are emulsifiers which are generally known to those skilled in the art. For ethoxylated products, the HLB value is calculated according to the formula HLB = (100 - L): 5, where L is the proportion by weight of the lipophilic groups, that is to say fatty alkyl or fatty acyl groups, in ethylene oxide adducts, expressed as a percentage by mass. When selecting suitable nonionic oil-in-water emulsifiers according to the invention, it is particularly preferable to use a mixture of nonionic oil-in-water emulsifiers to optimally adjust the stability compositions according to the invention. Each emulsifier component thus provides part of the total HLB value or of the average HLB value of the mixture of oil-in-water emulsifiers according to their proportion by weight in the total amount of oil-in-water emulsifiers. . According to the invention, the average HLB value of the mixture of oil-in-water emulsifiers is from 10 to 19, preferably from 12 to 18 and particularly preferably from 14 to 17.

    The cosmetic agents according to the present invention also contain at least one oily component in a total amount of 0.05 to 15% by weight. By oily component is meant cosmetic oils according to the invention. For the purposes of the present invention, the term “cosmetic oil” is intended to mean an oil suitable for cosmetic use and immiscible with water whatever the proportions. The cosmetic oil used according to the invention is neither an odoriferous substance nor an essential oil.
    The cosmetic agents according to the invention contain as cosmetic oil at least one substance chosen from the group comprising cosmetic oils which are liquid at 20 ° C. and at 1013 hPa.
    In the context of the present invention, the cosmetic oil liquid at 20 ° C. and 1013 hPa is chosen from the group (i) volatile cyclic silicone oils, in particular cyclic and linear silicone oils; (ii) volatile oils other than silicone oils, in particular liquid paraffinic and isoparaffinic oils; (iii) non-volatile silicone oils; (iv) non-volatile oils other than silicone oils; and (v) their mixtures.
    According to the invention, the term “volatile oil” designates oils having a vapor pressure of 2.66 Pa to 40,000 Pa (0.02 to 300 mm Hg) at 20 ° C and an ambient pressure of 1013 hPa, of preferably from 10 to 12,000 Pa (0.1 to 90 mm Hg), more preferably from 13 to 3,000 Pa (0.1 to 23 mm Hg), in particular from 15 to 500 Pa (0.1 to 4 mm Hg).

    According to the invention, it may be preferable to use mixtures of volatile silicone oils and volatile oils other than silicone oils in the antiperspirant cosmetic agents according to the invention, since this gives the skin a drier feel. In addition, in the context of the present invention, it may be preferred that the antiperspirant cosmetic agents contain a non-volatile silicone oil and / or a non-volatile oil other than a silicone oil to mask the insoluble constituents such as talc or the dried ingredients on the skin.
    The use of mixtures of non-volatile and volatile cosmetic oils is particularly preferred according to the invention since it makes it possible to adjust parameters such as the feel of the skin, the visibility of the residue or the stability of the antiperspirant cosmetic agent according to the invention and therefore to better adapt the latter to the needs of the consumer.
    The volatile cosmetic oils are usually chosen from cyclic silicone oils bearing the name INCI Cyclomethicone. The INCI name Cyclomethicone designates in particular cyclotrisiloxane (hexamethylcyclotrisiloxane), cyclotetrasiloxane (octamethylcyclotetrasiloxane), cyclopentasiloxane (decamethylcyclopentasiloxane) and cyclohexasiloxane (dodecamethylcyclohexasiloxane). These oils have a vapor pressure of approximately 13 to 15 Pa at 20 ° C. Cyclomethicones are known in the prior art as being oils well suited for cosmetic compositions, in particular for deodorant compositions such as sprays or sticks. Due to their persistence in the environment, it may be preferable according to the invention to avoid the use of cyclomethicones. In a particularly preferred embodiment, the compositions according to the invention and used according to the invention contain from 0 to less than 1% by weight, preferably 0.1% by weight maximum of cyclomethicones, relative to the weight of the composition , the propellant possibly present not being taken into account.

Residues of constituents which are not soluble in the composition, such as antiperspirant active principles (= antiperspirant aluminum salts) or talc can be successfully masked using a non-volatile oil. In addition, a mixture of different oils, in particular a non-volatile oil and a volatile oil, makes it possible to precisely regulate certain parameters such as the sensation on the skin, the visibility of the residue or the stability of the composition according to the invention and better adapt them to consumer needs. Preferred agents according to the invention are characterized in that the cosmetic oil, which is neither an odoriferous substance nor an essential oil, comprises at least one volatile oil having a vapor pressure ranging from 10 to 3000 Pa at 20 ° C, which is neither an odoriferous substance nor an essential oil, in a total amount of 0.1 to 100% by weight, particularly preferably 10 to 90% by weight, relative to the total weight of the cosmetic oils respectively .
