Description

 Cosmetic or dermatological preparations with high

Hautbefeuchtungsmittelanteil

The invention encompasses cosmetic or dermatological preparations comprising a combination of polyacrylate and polyacrylamide thickener. Despite a high proportion of skin moisturizing agent, the preparations have advantageous stability and product sensor technology.

Skin moisture is a term from the cosmetics industry. Healthy skin has a natural moisture. Only when the human skin shows anomalies with regard to dryness, does the lack of skin moisture come into play. Apart from pathological causes, the age of the human skin and the pigmentation also play a role. An important role in the hydration of the skin is played by moisturizing factors, e.g. Urea. These can be supplied to the skin by skin care products.

Normally, human skin does not need any natural moisture maintenance tools. However, unhealthy lifestyles, dry air (especially in solariums and heated indoor spaces), environmental stresses, stress and long sunbaths contribute to the removal of moisture. Even long and hot baths and detergent residues in clothing cause the loss of important components of the skin's hydrolipid system. To prevent dehydration of the skin one uses

Moisturizers. Even moisturizing soaps and largely soap-free detergents give the fat back to the skin. This makes it smoother and smoother again. In particular, body cleansers that are natural are recommended

Do not destroy the acid mantle of the skin (pH of the skin = 5.5).

In some apartments, the ventilation is not possible as usual due to negative environmental conditions, so-called humidifiers can be used to support a healthy skin moisture.

Moisturizers, also referred to as moisturizers, are substances or mixtures of substances which impart the property to cosmetic or dermatological preparations after application or spreading on the surface of the skin

Moisturizing the horny layer (also called transepidermal water loss (TEWL) called) and / or to influence the hydration of the horny layer positively.

A disadvantage has hitherto been that a high proportion of humectants in emulsions meant that the care emulsions had an unacceptable consistency and a non-desired by the user stickiness. It is desirable to provide preparations which can be provided at high skin moisturizer content, in particular a high polyol / glycol content, in particular glycerol content, without any loss of product sensor technology.

Thickeners are auxiliaries for establishing a suitable product consistency and a suitable flow behavior of cosmetic or dermatological preparations. They are preferably used in emulsions and surfactant-containing cleaning products.

The substance group of the thickeners can be roughly into the natural thickeners, such as starch, gelatin, alginates, the modified natural substances, such as cellulose ethers or

Hydroxyethyl cellulose, and the fully synthetic polymers, such as. As polyacrylates, divide.

Known natural or modified thickeners include polysaccharides, xanthan gum, cellulose ethers and other cellulose derivatives such as carboxymethylcellulose, hydroxyethylcellulose, gelatin, starch and starch derivatives, sodium alginates,

Fatty acid polyethylene glycol ester, agar-agar, tragacanth or dextrins and mixtures thereof. Further thickeners are known on the basis of silicates or modified clays such as bentonites or hectorites or their derivatives.

Examples of the polyacrylate thickeners are polyacrylates from the group of so-called carbopols, for example Carbopols of the types 980, 981, 1382, 2020, 2984, 3128, 5984 and permutants TR1, TR2, in each case individually or in combination.

Thus Carbopol 3128 is an acrylates / C 10-30 alkyl acrylate crosspolymer, a copolymer of C10-30 alkyl acrylate and one or more monomers of acrylic acid, methacrylic acid and their simple ester branched with an allyl ether of sucrose or an allyl ether of pentaerythritol.

WO 2006134038 A1 mentions permuiens TR 1 and Carbopol 3128 which are distinguished on the one hand by very good emulsifying properties but on the other hand also lead to a highly shear-thinning, theological behavior as preferred gel and structure formers. That they form a strong structure, which spontaneously collapses under shear.

As polyacrylamide thickener are also used as anionic or cationic modified products (anionic and cationic polyacrylamides), the z. B. by copolymerization of acrylamide with sodium acrylate or quaternary ammonium acrylates are obtained according to the following structure

Known polyacrylamides are the crosslinked copolymer with the trade name Sepigel 305 (CTFA name: polyacrylamide / C13-14 isoparaffin / Laureth 7) or Simulgel 600 (CTFA name: acrylamide / sodium acryloyldimethyltaurate copolymer / isohexadecane / polysorbate 80) from SEPPIC.

Also known is the SEPI PLUS 265, an acrylamide / ammonium acrylate copolymer in admixture with polyisobutenes and polysorbate 20, the company SEPPIC.

Cosmetic preparations comprising Sepiplus 265 are known, for example, as an anti-age product Nutri 35/50 comprising glycerol at 2% by weight, polyglyceryl-4 stearates at 3% by weight and other customary cosmetic constituents, and from US 20070237735.

In EP 1752133 A1 polyacrylamides and in particular the Sepiplus 265 in

Hair treatment agent described.

As each cosmetic preparation, depending on the application, the

Impact ingredients and the form of application and packaging must be designed, there is no universal thickener but it must always be selected and combined individual thickeners to meet the respective requirements.

However, when selecting thickeners, the cosmetic specialist is often faced with the problem of ensuring the stability of the preparation and taking into account sensory aspects.

This problem, the provision of a stable cosmetic or dermatological preparation and at the same time pleasant product sensors, the present invention. Formulations with a high polyol / glycol content or glycerol content above 5% by weight, in particular more than 10% by weight, based on the total mass of the preparation, are often difficult to disperse on the skin and penetrate slowly into the skin. Although these systems are distinguished by good skin moisturizing performance, they often also have a sensor system that is unattractive to the consumer.

To improve this circumstance is another object of the present invention.

Surprisingly, the use of polyacrylamide thickeners in combination with acrylate thickeners and in particular powder raw materials in cosmetic or

dermatological preparations, which comprise a high proportion of skin moisturizers such as glycerol, to a relatively attractive sensors.

The invention is a cosmetic or dermatological preparation comprising a. ) one or more thickeners based on polyacrylate,

b. ) one or more polyacrylamide-based thickeners and skin moisturizers, in particular one or more polyols, glycols, in particular glycerol, with a proportion of at least 5% by weight, based on the total mass of the preparation.

Particularly preferred glycols are propylene glycols and butylenes glycols.

As polyols are the 1, 2 alkanediols, especially 1, 2-pentanediol, 1, 2-hexanediol and 1, 2-octanediol, skin moisturizers advantageous. The latter are preferred in

Use concentrations in the range between 0, 1 and 2 wt.%, Preferably 0.2 to 1 wt.%, Particularly preferably 0.3 to 0.75 wt.%, Based on the total mass of the preparation used.

The improved product sensors of the preparations according to the invention, as listed in the examples, compared to preparations without the thickener combination have been carried out according to the Sensory Spectrum method, sensory tests on volunteers.

More detailed descriptions of the method can be found in Civille, GV (1991) Tactile Properties of Skin Care Products - Descriptive Analysis. Cosmet. Toiletries, 106, 83-88, as well as ASTM Standard Practice for Descriptive Skinfeel Analysis of Creams and Lotions / Designation E 1490-03. With regard to the stability of the preparations according to the invention are stress tests

has been carried out, the improved storage stability of the inventive

Prepare preparations with a high skin moisturizing proportion, in particular glycerol content.

Stress tests are carried out under different environmental conditions (heat, cold and room temperature) over a storage period of up to 360 days. This is followed by an organoleptic assessment of the stability patterns. Furthermore, the pH value and the viscosity or consistency are monitored over a period of up to 180 days.

As polyacrylate-based thickeners according to the invention, in particular acrylates and acrylate crosspolymers are understood.

 The chemical nature of these acrylates, trade name Carbopol, is generically referred to as "carbomers" according to USP-NF (U.S.A. Pharmacopeia), European Pharmacopoeia, British Pharmacopoeia, United States Adopted Names Council (USAN), and International Nomenclature for Cosmetic Ingredients (INCI).

 The Japanese Pharmacopoeia designates Carbopol homopolymers as "carboxyvinyl polymer" and "carboxy polymethylene." The Italian Pharmacopoeia identifies Carbopol 934P as "carboxy polymethylene" and the German Pharmacopoeia names Carbopol 980NF as "polyacrylic acid."

 Carbopol copolymers, such as Carbopol 1342 NF and 1382, are referred to by the USP-NF as "carbomers", which are also named "Acrylates / C10-C30 Alkyl Acrylates Cross Polymers" according to INCI

Thus, the acrylate crosspolymers commercially available under the names Pemulen TR1 and TR2, Carbopol 1342, 1382, ETD 2020, Ultrez 21 (Lubrizol Advanced Materials) as well as the commercial acrylates designated Carbopol 954, 5984, 980, 981, and 7 or Carbopol 2984 preferably to choose as polyacrylate-based thickener.

In particular, the acrylate / C 10-30 alkyl acrylate crosspolymer to be used as the polyacrylate thickener, as Carbomer 3128 or Pemulen TR1, to choose.

The proportion of polyacrylate thickeners, in particular acrylates / C10-30 alkyl acrylates

Crosspolymer is preferably selected in a proportion of 0.01 wt.% To 1, 0 wt, preferably in the range of 0.2 to 0.7 wt.%, Based on the total mass of the preparation.

Preferred polyacrylamide thickeners are acrylamides / ammonium acrylate copolymers selected.

 Such a preferred polyacrylamide-based thickener commercially available as Sepiplus 265 is commercially available.

In the Sepiplus 265 the acrylamide / ammonium acrylate copolymer is offered in the mixture with polyisubutylene, polysorbate 20, sorbitan isostearate and water.

Further commercially available polyamide thickeners are available, for example, under the names Sepiplus 250 (with mineral oil and polysorbate 20) from Seppic and the Bozepole CV from Clariant.

 The polyacrylamide-based thickeners are often only available in mixtures with the listed solvents PIB, etc. in order to improve their handling, for example to prevent the formation of dust.

The proportion of polyacrylamide thickeners, in particular acrylamide / ammonium acrylate copolymer, is preferably selected in an amount of 0.1 to 4% by weight, in particular in the range of 0.3 to 2% by weight, based on the total mass of the preparation.

Preference is given to a combination of a polyacrylamide thickener, in particular

Acrylamide / ammonium acrylate copolymer (Sepiplus 265) and one or two

various thickeners from the group of polyacrylates, more precisely the acrylate

Crosspolymers, combined.

Preferably, further or other thickeners are not used.

The preparations further advantageously comprise one or more

Skin moisturizer with a content of more than 5% by weight, preferably more than 10% by weight, based on the total mass of the preparation.

Further particularly preferred moisturizers are propylene glycols and butylene glycols.

The 1, 2 alkanediols, especially 1, 2-pentanediol, 1, 2-hexanediol and 1, 2-octanediol, are advantageous Hautbefeuchter.Der due to the high proportion of glycerol thereby expected disadvantage of a sticky sensor is not surprisingly occurred.

The preparations furthermore advantageously comprise one or more powder raw materials.

A powder is a very finely ground, dry solid that is used in cosmetics. The powder carriers exist depending on the application Silicates (talc and kaolin), carbonates (magnesium or calcium carbonate), oxides (zinc oxide, titanium dioxide), organic zinc and magnesium salts (stearates, laurates and undecanates) or sugar derivatives. The powder raw materials from the group of sugar derivatives are, for example, starch and / or starch derivatives or cyclodextrins and / or

Cyclodextrin derivatives.

Known starch powders are, for example, distarch phosphate, tapioca starch, acetyl or adipic acid substituted starch, hydroxypropylated starch, starch substituted with N-octenyl succinate, corn starch, 2-hydropropyl ether modified starch and

Hydroxypropyl starch phosphate ester.

Tapioca or tapioca starch is an almost tasteless starch, which is made from the processed and dried cassava root (cassava).

From the group of cyclodextrins, the α-, ß-, y- and hydroxypropyl-ß-cyclodextrins are known.

Preferred powder raw materials to be selected are methyl methacrylates, polymethylsilsesquioxanes, tapioca starch, distarch phosphates, nylon, polyamides-5, aluminum starch

Octenylsuccinates and acrylonitrile-methacrylonitrile-methyl-methacrylate copolymer.

Although the powder methyl methacrylate crosspolymer is also a polymer, it has no thickening properties due to its chemical structure.

The purder raw material (s) are preferably to be selected in a proportion in the range from 0.5% by weight to 4% by weight, based on the total mass of the preparation.

Particularly advantageous are methyl methacrylate crosspolymer, polymethylsilsesquioxane, tapioca starch and distarch phosphates.

 These powder raw materials are used in particular to a proportion of 0.5 to 3 wt.%, Based on the total mass of the preparation

According to the invention are methyl methacrylate crosspolymer and / or

Polymethylsilsesquioxane particularly advantageous to use as a powder raw material.

In the case of a restriction to preferred raw materials, the total proportion of powder raw materials is preferably still to be selected in the stated range of shares or only the preferably mentioned powder raw materials are present in the preparation in the stated range of proportions. The cosmetic and dermatological preparations in the sense of the present invention leave no greasy or sticky impression on the skin, are extremely tolerated by the skin, are storage-stable and are furthermore surprisingly characterized in that they have an extraordinary skin moisturizing performance. The

Skin moisturizing performance is determined according to those known from the literature

Heinrich, U. Koop et al., International Journal of Cosmetic Science, 2003, 25, 45-53, E. Berardesca, Skin research and technology 1997, 3, 126-132).

A disadvantage has hitherto been that a high proportion of humectants in preparations meant that the care emulsions an unacceptable consistency and from the

User unwanted stickiness had.

 This fact, too, the present invention meets due to the

Thickener combination according to the invention.

Likewise advantageously, the formulations are formulated on the basis of an emulsion.

As an application form of the preparations according to the invention, e.g. called: solutions, suspensions, emulsions, PIT emulsions, pastes, ointments, gels, creams, lotions, powders, soaps, surfactant-containing cleaning preparations, oils, aerosols and sprays. Other applications are e.g. Sticks, shampoos and shower baths. The preparation may contain any customary carrier substances, auxiliaries and optionally further active ingredients.

Lipids are fats and fat-like substances. For cosmetics, they are of importance, above all, as emollient ingredients and as skin-specific lipids of the horny layer, which are stored between the horny cells. They enable the skin to store moisture. In addition to the nourishing aspect, lipids become the cosmetic

Preparations added to ensure better distribution on the skin and to improve the sensory properties of the preparations. In many

cosmetic preparations are added for these reasons, volatile silicone oils. In particular, cyclomethicones are the cosmetic for these reasons

Preparations added.

Cyclomethicones, eg INCI name for an octamethylcyclotetrasiloxane, have the general formula where I = 3 - 6

 Offered are, for example, cyclomethicone / decacyclopentasiloxane (D5) or cyclomethicone / dodecamethylcyclohexasiloxane (D6). The mixtures can be used on their own or in appropriate formulations as volatile silicone compounds (Cosmet. Toiletries 107, No. 5, 27 [1992]).

 Silicone containing oils include the high molecular weight polydiorganosiloxanes known as silicone gums. Silicone gums are described for example in US 4152416. High molecular weight means a molecular weight of about 200,000 to 1,000,000 g / mol.

Known silicone gums are polymeric polydimethylsiloxanes (INCI name:

Dimethicone), e.g. As the products sold under the name DC 200 by Dow Corning products, polyphenylmethylsiloxanes (INCI name: Phenyl Trimethicone), z. For example, the commercial product DC 556 fluid from Dow Corning, silicone glycol copolymers (INCI name: Dimethicone Copolyol), z. For example, the commercial products DC 190 and DC 193 Dow Corning, esters and partial esters of silicone glycol copolymers, such as those sold by Fanning under the trade name Fancorsil LIM (INCI name: Dimethicone Copolyol Meadowfoamate), dimethylsiloxanes with hydroxy - end groups (INCI name: dimethiconol), z. For example, the commercial products DC 1401 and Q2-1403 from Dow Coming.

 For cosmetic applications, further known silicone gums are, for example, SE 30, SE 33, SE 54 and SE 76 from General Electric.

 Also known are the silicone gums from Dow Corning with the name Dow Corning® 1501 fluid (cyclopentasiloxanes, dimethiconol); Dow Corning® 1503 Fluid (dimethicone, dimethiconol), Dow Corning® CB 1556 fluid (phenyl trimethicone,

Dimethiconol) and Dow Corning® BY 25-320 (C13-16 isoparaffin, dimethicone).

Mixtures of silicone fluids and volatile silicone oils, such as cyclomethicones, and silicone gums are also known in cosmetic preparations.

The silicones to be used according to the invention preferably consist of light, e.g.

volatile cyclic compounds such as cyclomethicones (D5 / D6) as well as minor proportions of heavier linear silicone compounds

such as dimethicone with siloxane units greater than 20 or so-called. Silicone gums (such as DC 1501 fluid). The cyclic compounds give the pleasant feeling on the skin, ensure very good spreadability and silky sensory properties directly on the distribution process of the product on the skin. The linear compounds give a silky residue on the skin even after 5 minutes or even longer periods after the last application of the product

Consumers are perceived as caring.

Preferred concentration ranges for the cyclomethicones according to the invention are from 3.0 to 10.0% by weight, preferably from 4.0 to 7.0% by weight, based on the total weight of the formulation.

 In accordance with the invention preferred use concentration ranges for the linear

Silicone compounds are in the range of 0.5 to 2.5 wt.%, Preferably 1, 0 to 2.0 wt.% Based on the total weight of the formulation.

The total content of the silicone phase in the formulation is therefore preferably between 3.5 and 12.5% by weight, preferably between 4.0 and 10.0% by weight, more preferably between 5.0 and 7.5% by weight, based on the total weight of the preparation.

With regard to the skin feel, it has been found to be advantageous according to the invention that the ratio of cyclomethicones to the long-chain linear silicone compounds should be between 10: 1 and 1: 1, preferably between 5: 1 and 2: 1. In other words, in the preferred range, a proportion of cyclic compounds which is at least always twice as high in relation to the linear silicones is preferably present in the formula according to the invention.

 Long-chain means an Si atomic number greater than 20.

The present combination of one or more polyacrylate thickeners, especially acrylates / C 10-30 alkyl acrylate crosspolymer, and one or more

Polyacrylamide thickeners, in particular acrylamide / ammonium acrylate copolymer, are suitable for improving the product sensors of cosmetic or dermatological preparations which comprise skin moisturizing agents, polyols, glycols, in particular glycerol, in a proportion of more than 5% by weight.

Particularly advantageous are cosmetic or dermatological preparations with regard to their product sensor system comprising 0.2 to 0.7% by weight of acrylates / C 10-30 alkyl acrylates

Crosspolymers, 0.3 to 2 wt.% Acrylamide / ammonium acrylate copolymers, polyols and / or glycols or glycerol in a proportion of more than 5 wt.%, And one or more powder raw materials selected from the group consisting of group methyl methacrylates

Crosspolymer, Polymethylsilsesquioxane, Tapioca Starch, Distarch Phosphate, Nylon, Polyamide-5, Aluminum Starch Octenylsuccinate and Acrylonitrile-methacrylonitrile-methyl-methacrylate copolymer.

As the above stability studies show, the combination of one or more polyacrylate thickeners, in particular acrylates / C 10-30 alkyl acrylate crosspolymer, and one or more polyacrylamide thickeners, in particular acrylamide / ammonium acrylate copolymer, for improving the storage stability of cosmetic or dermatological preparations comprising one or several polyols and / or glycols in an amount more than 5 wt.%, Based on the total mass of the preparation to use.

Preferably, further or other thickeners are not used in the preparation.

In the case of a restriction to the preferred thickeners mentioned, the total proportion of polyacrylate or polyacrylamide thickeners is furthermore preferably specified

Share range to choose or it is only the preferred thickener in the

Preparation available in the specified range share.

 This restriction also applies to other than preferred substances or groups of substances, such as powder raw materials, UV filters. That in the case of a restriction to preferred proportions and a simultaneous restriction to preferred species of these groups, it is according to the invention that in each case no other species of these groups are contained in the preparation.
