[0002] Cleansing preparation for shaving and facial cleansing

[0003] The present invention describes a cosmetic cleansing preparation intended in particular for shaving preparation, but also for facial cleansing. The preparation contains a surfactant system comprising a selection of specific surfactants. The preparation is particularly free of polymeric thickeners and sulfate surfactants.

[0004] Cleansing the skin and its appendages is a part of daily life in many cultures today, almost comparable to eating and drinking. Cleansing primarily involves removing dirt, which often lies on the skin's surface in the form of a film. This film consists of solid or liquid components that have come onto the skin from the outside. Excess skin lipids and dead body cells are also part of the film. Surfactants in the cleaning compositions remove the components of the film from the skin during the rinsing process and they end up in the wash solution. In addition to removing the film of dirt, depending on the cleaning conditions, the skin's surface lipids, such as barrier lipids, can also be dissolved to a greater or lesser extent by the surfactants in the cleaning preparations and removed during the rinsing process.Therefore, attempts are made to mitigate these phenomena by selecting suitable surfactants and / or incorporating moisturizing components.

[0005] This is even more true for facial skin, which is generally more sensitive than the rest of the skin on the human body.

[0006] Shaving preparation is a procedure, particularly for wet shaving, that softens the (beard) hair, thus reducing the effort required during shaving. This reduces pulling on the hair shaft ("tugging"). Softening of the (beard) hair is achieved by water absorption. However, the sebum layer of the hair must be removed so that water absorption can occur sufficiently well and quickly. Consumers are increasingly demanding products, including cleaning products, that do not harm the environment. There are two aspects to consider here: firstly, such products should consist largely or entirely of natural or nature-based ingredients, and secondly, the ingredients and the entire product should be readily biodegradable.

[0007] The term "natural" in the context of natural cosmetic ingredients is defined in ISO 16128. According to this standard, natural cosmetic ingredients can be summarized as substances obtainable from plants, animals, minerals, or microorganisms, including those obtained from these sources through physical processes, fermentation processes (only those fermentation processes that also occur in nature and that result in products that also occur in nature), and other manufacturing methods without intentional chemical modification. The microorganisms must be those that have not been genetically modified.

[0008] For the purposes of the present invention, nature-based substances, in particular nature-based surfactants, are compounds derived from natural starting materials or produced from natural starting materials. To assess the extent to which a substance is nature-based, the method for determining the "Biorenewable Carbon Index" (BCI) can be used. This method determines the percentage of carbon atoms originating from renewable plant or animal sources relative to the carbon atoms from non-renewable, petrochemical sources. See HAPPI July, 58-60, 2009.

[0009] The term biodegradability describes the process of decomposition of organic compounds by living organisms, especially saprobiotics. Ideally, this results in inorganic substances such as CO2, O2, and ammonia, compounds that can be reused by plants and microorganisms to build organic compounds.

[0010] Organic chemical compounds that are readily biodegradable are classified according to OECD 301, and for cosmetic compositions, usually according to OECD 301B. These substances or compositions can be degraded rapidly and completely. Organic chemical compounds classified according to OECD 302 are, although limited, generally biodegradable.

[0011] Furthermore, cleansing preparations should have a suitable consistency. On the one hand, the preparations should be easy to remove from the packaging; on the other hand, they must not be too runny, as good distribution on the skin and staying on the skin during the washing process and shaving preparation are essential to achieve a cleansing effect and a comparatively comfortable shave. It follows that the cleansing preparations must have a certain viscosity to meet the aforementioned criteria. This viscosity is usually described by the viscosity; for shower gels, for example, a viscosity of 3,000 to 10,000 mPa-s is disclosed (Kosmetik; Umbach, 1995; 1 ​​12-1 13).

[0012] To achieve the desired viscosity, polymer thickeners are often incorporated into cleaning preparations. These polymer thickeners are hydrocolloids. These are macromolecules that have a largely linear shape and possess intermolecular interaction forces that enable secondary and primary valence bonds between the individual molecules, thus forming a network-like structure. They are partially water-soluble natural or synthetic polymers that form gels or viscous solutions in aqueous systems. They increase the viscosity of the water by either binding water molecules (hydration) or absorbing and enveloping the water in their intertwined macromolecules, while simultaneously limiting the water's mobility.Such water-soluble or water-swellable polymers represent a large group of chemically very diverse natural and synthetic polymers whose common characteristic is their solubility or swellability in water or aqueous media. This requires that these polymers possess a sufficient number of hydrophilic groups for water solubility and are not overly cross-linked. The hydrophilic groups can be non-ionic, anionic, or cationic.

[0013] The group of cosmetically and dermatologically relevant hydrocolloids can be divided into:

[0014] • organic, natural compounds such as agar-agar, carrageenan, tragacanth, gum arabic, alginates, pectins, polyoses, guar flour, locust bean gum, starch, dextrins, gelatin, casein, • organic, modified natural substances such as carboxymethylcellulose and other cellulose ethers, hydroxyethyl and propylcellulose and the like,

[0015] • organic, fully synthetic compounds, such as polyacrylic and polymethacrylic compounds, vinyl polymers, polycarboxylic acids, polyethers, polyimines, polyamides,

[0016] • inorganic compounds such as polysilicic acids, clay minerals such as montmorillonites, zeolites, silicic acids.

[0017] Polyacrylates are frequently used thickeners, including acrylate-alkyl acrylate copolymers or copolymers of C-10-15 alkyl acrylates and one or more acrylic acid monomers, and many others.

[0018] The thickeners can therefore be of synthetic origin and have no equivalent in nature. Therefore, no natural degradation pathways exist, and such polymers are generally poorly biodegradable.

[0019] Examples of this are the documents DE 102010022063 A1, DE 10201 1078087 A1, WO 01 / 76552 A2 and WO 2012 / 006402 A1.

[0020] However, there are ways to avoid polymeric thickeners. In these cases, fatty alcohol ethoxylates, fatty acid alkylolamides, ethoxylated glucose esters, ethoxylated partial glycerides, or table salt are used. Surfactant mixtures of alkyl betaines and alkyl polyglucosides are also said to have a thickening effect (Kosmetik, Umbach, 1995, 109-110).

[0021] Preparations thickened with table salt are listed in the document

[0022] DE 102020202554 A1 and in the products Watermelon Mint Coconut Milk Refreshing Shower (Mintel entry number 9502082), Banana Acai Coconut Milk Refreshing Shower (Mintel entry number 9495102), and Raspberry Blueberry Almond Milk Refreshing Shower (Mintel entry number 9378812). All of these preparations / products contain sodium laureth sulfate, which is a sulfate surfactant, in addition to table salt.

[0023] Sulfate surfactants are known to have a certain irritating potential for the skin and mucous membranes. For facial skin, which is generally more sensitive than the skin of the rest of the human body, it is therefore desirable to avoid sulfate surfactants. The objective was therefore to provide preparations for cleansing facial skin and preparing for shaving that do not contain sulfate surfactants and polymer thickeners, yet still provide effective shaving preparation and cleansing for the skin and are sufficiently mild. The preparations should have a consistency that allows for easy removal from the packaging, but not be too runny, ensuring that they are distributed and remain on the skin during the cleansing process.

[0024] This problem was solved by incorporating a special surfactant system into a cleaning preparation; the surfactant system includes amino acid surfactants, amphoteric surfactants and non-ionic surfactants.

[0025] Document EP 2682161 B1 discloses certain surfactant systems that have a thickening effect within a defined pH range. Individual raw materials and various systems are described, including binary systems, ternary systems, and a quaternary system. Eliminating sulfate surfactants, and thus also the widely used sodium laureth sulfate, is not suggested, since the surfactant systems according to EP 2682161 B1 sometimes contain sodium laureth sulfate, and there is no description of any disadvantages associated with these systems.

[0026] Thus, the above-mentioned object is achieved by a cleaning preparation containing a surfactant system consisting of

[0027] - an acylsarcosinate,

[0028] - at least one amphoteric surfactant, preferably selected from alkylpropyl betaines and / or alkylamphoacetates,

[0029] - at least one further anionic surfactant selected from the group of acyl isethionates, acyl glutamates, acyl glycinates, acyl alaninates and / or taurates and

[0030] - optionally consists of at least one nonionic surfactant from the group of alkyl polyglucosides, without containing any sulfate surfactant. It is advantageous if the pH of the cleaning preparation is between 4.2 and 5.0.

[0031] The cleaning preparation according to the invention is an aqueous preparation; the water content is in the range of 50 to 95 wt.%, preferably 60 to 90 wt.%, based on the total weight of the cleaning preparation.

[0032] The surfactant system according to the invention is a surfactant system which always consists of at least three components, namely an acyl sarcosinate, at least one amphoteric surfactant, preferably selected from alkylpropylbetaines and / or alkylamphoacetates, at least one further anionic surfactant selected from the group of acyl isethionates, acylglutamates, acylglycinates, acylalaninates and / or N-acyltaurates and optionally at least one nonionic surfactant from the group of alkylpolyglucosides.

[0033] Surfactants reduce the surface tension of a liquid or the interfacial tension between two immiscible liquids. Dispersions form. Surfactants can also act as solubilizers. For the purposes of the present invention, surfactants are understood to mean only washing-active substances (detergents). Such surfactants are usually divided into classes based on the surfactant's charge. A distinction is made between anionic, cationic, amphoteric or zwitterionic, and nonionic surfactants.

[0034] The surfactant system according to the invention is characterized by a combination of selected surfactants, which are described below.

[0035] Acylsarcosinates can be described by the formula

[0036] RCON(CH3)CH2COOM, where R is an alkyl or alkenyl radical having 5 to 29 carbon atoms, preferably 7 to 21 carbon atoms, and M is a hydrogen atom or a metal cation. Further preferred is an acyl sarcosinate with an alkyl radical of 11 carbon atoms, i.e., a lauroyl sarcosinate. The lauroyl sarcosinate is even more preferably in the form of sodium lauroyl sarcosinate, which is available, for example, under the trade name Eversoft S-12 from Sino Lion (USA). Due to their chemical structure, acyl sarcosinates can be classified as anionic surfactants.

[0037] In the cleaning preparation according to the invention, the acyl sarcosinate is present in a concentration of 2.0 to 10.0 wt.%, preferably 2.0 to 6.0 wt.%, based on the total weight of the preparation. This information refers to the active content.

[0038] The following example should clarify what is meant by "active use concentration" or "active content" in the context of the present invention: If a raw material is present, for example, in the form of a 50% solution (for example, because it is only available in this form on the market), then - with a use concentration of this "raw material solution" of 8.0 wt.% - only an "active content" of 4.0 wt.%, based on the total weight of the preparation, is realized in the preparation.

[0039] The at least one further anionic surfactant is selected from the group of acyl isethionates, acylglutamates, acylglycinates, acylalaninates and / or N-acyltaurates.

[0045] Acylglycinates can be described by the following formula,

[0046] RCONHCH2COOM, where R is an alkyl or alkenyl radical having 5 to 29 carbon atoms, preferably 7 to 21 carbon atoms, and M is a hydrogen atom or a metal cation. Further preferred is an acylglycinate with an alkyl radical derived from a natural oil or fat, for example, alkyl radicals of fatty acids such as those found in palm oil, soybean oil, or coconut oil. The compound sodium cocoyl glycinate, which is available, for example, under the trade name Hostapon SG from Clariant, is particularly preferred.

[0050] RCON(CH3)(CH2)2SOOOM where R is an alkyl or alkenyl radical having 5 to 29 carbon atoms, preferably 7 to 21 carbon atoms, and M is a hydrogen atom or a metal cation. Further preferred is an N-acyl taurate with an alkyl radical derived from a natural oil or fat, for example, alkyl radicals of fatty acids such as those found in palm oil, soybean oil, or coconut oil. Very particular preference is given to the compound sodium methyl cocoyl taurate, which is available, for example, under the trade name Pureact WS Gone from Innospec Performance Chemicals.

[0051] In the cleaning preparation according to the invention there is at least one further anionic surfactant selected from the group of acyl isethionates, acylglutamates, acylglycinates, acylalaninates and / or N-acyltaurates with a total content of 0.5 to

The respective values ​​represent the active content.

[0060] The at least one nonionic surfactant according to the invention is selected from the group of alkylpolyglucosides.

[0061] Alkylpolyglucosides can be described by the following formula: where m can be the numbers 1 to 5 and n the numbers 5 to 21, preferably 9 to 17. The average number of glucose units is preferably 1.2 to 2, more preferably 1.2 to 1.8. It is preferred if the at least one alkyl polyglucoside is selected from the group consisting of coco-glucoside, decyl glucoside, lauryl glucoside and / or caprylyl / capryl glucoside, in particular lauryl glucoside and / or decyl glucoside.

[0062] Lauryl glucoside and / or decyl glucoside are biodegradable; the BCI of both surfactants is 100.

[0063] Lauryl glucoside can be purchased from BASF under the trade name Plantacare 1200 UP, for example, and decyl glucoside can be purchased from BASF under the trade name Plantacare 2000 UP.

[0064] The cleaning preparation according to the invention contains at least one alkyl polyglucoside in a total content of 0.5 to 4.0 wt.%, preferably 1.0 to 2.5 wt.%, based on the total weight of the preparation. The respective values ​​represent active contents.

[0065] According to the invention, it is advantageous if the surfactants in the surfactant system according to the invention are present in a specific weight ratio. For simplification, the acyl sarcosinate is referred to as surfactant A, the at least one amphoteric surfactant as surfactant B, the at least one further anionic surfactant as surfactant C, and the at least one nonionic surfactant as surfactant D. The weight ratios of (A + C): B: D advantageously range from 1.5:4.3:1 to 4.5:9.0:1. If the surfactant system does not contain an alkyl polyglucoside, the weight ratio of (A + C): B is advantageously 0.3:1 to 0.6:1.

[0066] In a preferred embodiment, the at least one further anionic surfactant is selected from the group of acyl isethionates and / or acylglutamates.

[0067] In a further preferred embodiment, the surfactant system comprises sodium lauroyl sarcosinate and sodium cocoyl isethionate or disodium cocoyl glutamate.

[0068] In a particularly preferred embodiment, the surfactant system consists of sodium lauroyl sarcosinate, cocoamidopropyl betaine, sodium cocoyl isethionate, and decyl glucoside or lauryl glucoside. In another particularly preferred embodiment, the surfactant system consists of sodium lauroyl sarcosinate, cocoamidopropyl betaine, disodium cocoyl glutamate, and decyl glucoside or lauryl glucoside.

[0069] For the purposes of the present invention, sulfate surfactants are understood to mean those surfactants that contain a sulfate group. Known examples of these sulfate surfactants are alkyl ether sulfates or alkyl sulfates; a well-known and widely used alkyl ether sulfate is sodium laureth sulfate. The cleaning preparation according to the invention is free of sulfate surfactants.

[0070] The cleaning preparation according to the invention is free of polymeric thickeners. What is meant by polymeric thickeners in the context of the present invention has already been described.

[0071] For the purposes of the present invention, "free from" means that less than 0.01% by weight, preferably less than 0.001% by weight, particularly preferably 0% by weight of the respective substances (f), based on the total weight of the preparation, are present.

[0072] It is advantageous if the preparation according to the invention is preserved by incorporating physiological salts of the acids benzoic acid, salicylic acid and / or sorbic acid.

[0073] If the physiological salts of the acids benzoic acid, salicylic acid and / or sorbic acid are contained in the preparation according to the invention, they are present in a total content of 0.1 to 0.5% by weight, preferably 0.25 to 0.5% by weight, based on the total weight of the preparation according to the invention.

[0074] The cleaning preparation according to the invention is free of parabens.

[0076] The preparation according to the invention can additionally contain at least one moisturizer. Moisturizers are substances or mixtures of substances which impart to cosmetic preparations the property of reducing moisture loss after application or distribution on the hair surface and / or positively influencing the hydration of the hair surface or the deeper layers. Advantageous moisturizers within the meaning of the present invention are, for example, glycerin, sorbitol, butylene glycol, propylene glycol, pentylene glycol, hexylene glycol, caprylyl glycol, decylene glycol, lactic acid and / or lactates, in particular sodium lactate, biosaccharide gum-1, glycine soja, ethylhexylglycerin, pyrrolidonecarboxylic acid and urea. Glycerin is preferably selected as the moisturizer. Two or more different moisturizers can also be included.

[0077] If at least one moisturizer is contained in the preparation according to the invention, it is present in a total content of 0.05 to 20% by weight, preferably 0.15 to 15.0% by weight, based on the total weight of the preparation.

[0078] To achieve a thickening effect with the claimed surfactant system, it is highly advantageous to adjust the pH to a value between 4.2 and 5.0. The pH can be adjusted using any physiologically compatible substances commonly used in the cosmetics industry. However, the use of an organic acid is preferred, with citric acid being particularly preferred.

[0079] The pH value was measured using a commercially available pH meter (e.g., Laboratory pH Meter 766, Knick).

[0080] Furthermore, it is advantageous if the preparation contains a perfume. Perfumes are mixtures of perfume raw materials. The perfume is advantageously present in a concentration of 0.05 to 1.0 wt.%, based on the total weight of the preparation.

[0081] The preparations according to the invention may contain cosmetic auxiliaries as are customarily used in such preparations, e.g., foam stabilizers, other polyols and their physiologically acceptable ethers and esters, antioxidants, complexing and sequestering agents, organic solvents, or other customary components of a cosmetic or dermatological formulation. The incorporation of plant extracts, water-soluble vitamins, and / or other active ingredients is particularly advantageous.

[0082] The preparation according to the invention can be prepared in any manner known and suitable for such a preparation in the StdT.

[0083] However, the following manufacturing method has proven advantageous:

[0084] - Providing water containing optionally one or more humectants,

[0085] - Add the surfactants of the surfactant system in any order while stirring, if the mixture is heated,

[0086] - Addition of the preservative(s),

[0087] - Addition of perfume (optional),

[0088] - Addition of dyes (optional),

[0089] - Adjust to the desired pH value, preferably while stirring.

[0090] The following manufacturing method has also proven to be beneficial:

[0091] - Preparation of water and surfactants of the surfactant system,

[0092] - Addition of preservative(s) and humectant(s), if necessary heating of the mixture,

[0093] - Addition of fragrances (optional),

[0094] - Addition of dyes (optional),

[0095] - Adjust the pH value, preferably while stirring, to the desired pH value.

[0096] The stirrer can be, for example, a dissolver stirrer, an anchor stirrer, or a blade stirrer from IKA. The stirrer should have a rotational speed of 50 to 2000 rpm; for the preparation of the invention, a stirrer capable of rotating the stirrer at 200 to 1500 rpm should be selected.

[0097] The preparation according to the invention advantageously has a specific viscosity or consistency; the viscosity is measured using a Rheomat proRheo 123 viscometer (spindle 1, 25°C, 62.5 rpm). The viscosity of the preparation according to the invention is 900 to 10,000 mPa-s, preferably 2,000 to 7,000 mPa-s. This viscosity value is measured 24 to 48 hours after production.

[0098] It is advantageous according to the invention if the cleaning preparation is transparent.

[0099] For this purpose, a transmission measurement is carried out using a commercially available UV-Vis spectrometer at 420 nm. The measurement is carried out in 1 cm disposable cuvettes against distilled water as a reference. A preparation is transparent within the meaning of the invention if the transmission values ​​reach at least 50% of the reference value.

[0100] In order to demonstrate that the above-described problem underlying the invention has been solved, various preparations were prepared and the pH value was adjusted to a value according to the invention and then the viscosity was determined.

[0102] The quantities given refer to the respective active content and to wt.%, unless otherwise stated.

[0103] Table 2 (= examples):

[0104] The quantities given refer to the respective active content and to wt.%, unless otherwise stated.

[0105] As can be seen from the tables, the surfactant system according to the invention can be used to obtain preparations that do not require the addition of sulfate surfactants and polymer thickeners and satisfactorily achieve all of the above-described objectives. In particular, the viscosity can be adjusted so that the preparations can be easily removed from the packaging and, after spreading on the skin, remain on the skin and beard hairs for a sufficiently long time to ensure good shaving preparation and effective cleansing.
