Abstract

The invention relates to cosmetic or dermatological anti-light preparations comprising a combination of polyacrylate and polyacrylamide thickener apart from one or more UV filters. Despite a lower UV filter content, the preparations are waterproof and have an improved UV protection performance, an advantageous stability and provide at the same time an improved tactile sensation to the user.

Description

Cosmetic or dermatological sunscreen preparations comprising a combination of polyacrylate and polyacrylamide thickener

The invention encompasses cosmetic or dermatological sunscreen preparations comprising a combination of polyacrylate and polyacrylamide thickener. The

Preparations have a water resistance without the film former are present. In addition, the preparations have a comparatively high light protection performance at low UV filter contents and, at high UV filter contents, advantageous stability and at the same time improved product sensor technology for the user.

It is known that by light radiation with a wavelength in the range of 280 to 400 nm, the human epidermis can be browned and that radiation with a

Wavelength in the range of 280 to 320 nm, known as UV-B, causes erythema and skin burns that may be detrimental to the formation of natural tan. The UV-B radiation should therefore be filtered out.

It is also known that UV-A radiation having a wavelength in the range of 320 to 400 nm, which tans the skin, can cause a change in the skin, especially in the case of sensitive skin or skin that is continuously exposed to solar radiation. In particular, UV-A radiation causes a loss of elasticity of the skin and the

Occurrence of wrinkles, leading to premature aging. It promotes the development of erythema or potentiates this response in some individuals, and may even be the cause of light-induced toxic or allergic reactions. It is therefore desirable to filter out the UV-A radiation as well.

In general, the light absorption behavior of sunscreen filter substances is very well known and documented, especially since in most industrialized countries there are positive lists for the use of such substances, which apply quite strict standards to the documentation. Depending on which area of the UV light is absorbed, a distinction is made between UV-B filters, UV-A filters and broadband filters, which show a filtering effect over the entire range of UV-A and UV-B. By appropriate selection of the UV filter and its concentration in the sunscreen one has the opportunity to influence the degree of shielding of the UV light. For the dosage of the substances in the finished formulations, however, the extinction values can at best be one

Provide guidance, because interactions with ingredients of the formulation or the skin itself may cause uncertainties. Furthermore, it is generally difficult to estimate in advance how uniformly and in which layer thickness the filter substance is or will be distributed in and on the horny layer of the skin. In addition to the influence of the binding ability of the UV filter in or on the skin is of great importance for the water resistance of the formulation. It is understandable that oil-soluble UV filters are better bound to the (lipophilic) surface of the skin or are more difficult to wash off this than water-soluble UV filters.

The effectiveness of sunscreen or the underlying UV filter is usually determined in biological efficacy tests under standardized conditions.

The sun protection factor LSF, often also called SPF (sun protection factor), indicates the extension of the sun exposure, which is made possible by using the sunscreen. It is the ratio of erythema threshold with sunscreen and erythema threshold without sunscreen.

To test the UV-A protection performance, the IPD method (IPD = immediate pigment darkening) is usually used. Here, similar to the determination of the sun protection factor, a value is determined which indicates by how much longer the skin protected with the sunscreen can be irradiated with UV-A radiation until the same pigmentation occurs as with the unprotected skin.

Another, Europe-wide established testing method is the Australian Standard AS / NZS 2604: 1997. The absorption of the preparation in the UV-A range is measured. To meet the standard, the formulation must absorb at least 90% of the UV-A radiation in the 320-360 nm range.

The SPF (Sun Protection Factor) will comply with the regulations of the

International SPF Test Method (COLIPA, May 2006) determined in vivo on human skin. At least 10 subjects are required for the test, and the confidence interval for the mean value must not exceed 17%.

Definition: SPF = quotient of minimal erythemal dose (MED) on protected and unprotected skin.

The MED is the lowest dose of UV radiation, which causes a slight but noticeable erythema (sunburn, erythema) after 16-24h. Radiation sources are solar simulators, mostly with xenon lamps.

UV radiation of different frequency / wavelength penetrates the tissue at different depths. Therefore, the type of damage is wavelength dependent. The UV-A protection is of particular importance here, since this UV radiation (UV-A (wavelength 315-400 nm), is essentially responsible for skin aging UVA filters are among the chemical sunscreen filters. They penetrate the skin, absorb the high-energy UV radiation there and convert it into heat or light energy, which can no longer cause any damage. Although it is for the determination of

UVA protection currently has no recognized test method (in contrast to the COLI PA method for UVB filters), in practice the so-called UVA / UVB protection balance should apply.

In order to provide information on the UVA protection performance of a sunscreen product, various experimental models, both in vivo and in vitro, are used and derived statements are made on the packaging (UVA protection according to

Australian Standard, Persistant Darkening Factor & a). However, these figures are not comparable with each other. For this reason, the EU Commission has

In September 2006, a recommendation was published to increase the safety and transparency of sunscreen products. The EU recommendation provides 1/3 UVA protection in relation to UVB protection. So far, only the protection of

sunburn causing UVB rays regulated in the Kosmetikverordnung. With the new EU recommendation, each sunscreen should simultaneously protect against UVA radiation. The consumer should assume that UVA protection is guaranteed, which increases with increasing SPF value. For ethical reasons, an in vitro method is proposed. At the Beiersdorf AG in Hamburg, an in-vitro method for the determination of UVA as a function of the sun protection factor was developed: the UVA / UVB balance. In February 2005, the UVA / UVB balance was published as DIN 67502, making it the first official method for determining UVA protection in Europe. A method for measuring the UVA protection performance is currently also being worked on in the COLI PA because the industry demands a uniform method. The COLIPA is the

Umbrella organization of the European cosmetics industry, it gives u.a. Recommendations regarding the execution of the measurement method. The UVA / UVB balance is the basis of the method discussed there. It is modified to include a pre-irradiation with UV light to include some special UV filter systems. So far, the products have been tested without pre-irradiation. As a result, no information could be provided as to whether the protective effect of the product under real conditions is given by sun exposure. This advanced measurement method is called "COLIPA Ratio".

This means that UVA filters are used in relation of 1: 3 to UVB filters and thus the UVA protection is raised with increasing light protection. The EU recommendation provides 1/3 UVA protection in relation to UVB protection. This measurement method is called "COLIPA Ratio." The COLIPA ratio must be according to the formula UVB ".

<3.

UVA

The COLI PA ratio is the standard for determining UVA protection.

With regard to the stabilization and achievement of a high UV protection, there are various disclosures in the prior art.

EP 887069 A2, EP 0887068 A2 and EP 935959 A2 disclose a UV-A boosting by synthetic beeswax or natural beeswax.

Boosting means an increase in performance over preparations without, as here, beeswax.

EP 1965871 A2 discloses cosmetic preparations with a UV-A balance of greater than 35 containing one or more merocyanines.

Sunscreen formulations on the market often achieve adequate UV protection only by increased addition of UV filter substances.

This increased proportion of UV filter substances in turn leads to skin-friendlier preparations which feel dull and sticky, are difficult to rub,

more problematic to formulate and above all are not long-term stable.

It is therefore desirable to provide preparations which, with a high UV filter content, have improved or consistent product sensor technology and, above all, good stability, in particular storage stability, without resulting in losses in light protection performance or disadvantages in other effects of the preparations.

It would also be advantageous to meet the requirements for higher light protection without sacrificing product sensors.

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 the so-called carbopols, for example Carbopols of the types 980, 981, 1382, 2020, 2984, 3128, 5984 and permulenes 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.

In WO 2006134038 A1, the preferred gel and structure formers mentioned are permulenes TR 1 and Carbopol 3128, which, on the one hand, have very good emulsifying properties but, on the other hand, also lead to a high shear-thinning, rheological behavior. 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. Example, be obtained by copolymerization of acrylamide with sodium acrylate or quaternary ammonium acrylates 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 further customary cosmetic constituents, and from US 20070237735 A1.

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.

The water resistance of sunscreen preparations is another challenge to the cosmetic specialist.

O / W emulsions are easy to spread and suitable for oily skin and acne. A disadvantage is the low water resistance.

W / O emulsions are well suited for dry skin, have a high water resistance and are well combinable with pigments. But they are sticky, less well absorbed and are therefore not popular with some customers. Hydrodispersion gels are easily spreadable and result in a pleasant

Skin feel. They can be produced without emulsifiers and preservatives and are therefore well suited for people with sun allergies. They are suitable for hairy skin and greasy skin and acne, but have a low water resistance.

Sunscreens in sprays are easily dispersible, but usually have a low water resistance.

Waterproof sunscreen formulations are usually achieved by using film formers (including unimer or antarone types, as well as synchro waxes). However, these systems are characterized by an unattractive to the consumer sensors, i. they are often particularly dull, sticky and / or oily on the skin and bad in the skin.

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

Surprisingly, a combination of polyacrylate thickeners with polyamide thickeners has been found to be particularly suitable for excellent product sensing and

Consistent or improved sunscreen performance cosmetic or dermatological preparations with a comparatively low sunscreen filter proven.

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 c.) one or more UV filter substances with a content of more than 1% by weight, based on the total mass of the preparation.

It is advantageous to add one or more powder raw materials to the preparation. More preferably, it is possible to dispense with the addition of film formers which are usually added in order to achieve water resistance.

The preparations according to the invention have improved stability and improved stability over preparations with the same or higher UV filter content and film formers

Water resistance without the film former are included in the preparation.

Film formers are substances for achieving the water resistance of the preparation. These are characterized by the following property: If a consistent or even better SPF is dissolved on film formers in water or other suitable solvents and the solution is then applied to the skin, a film is formed after the solvent has evaporated essentially serves to fix the sunscreen filter substances on the skin and above all to ensure or increase the water resistance of the preparation on the skin.

Known film formers which can be dispensed with according to the invention are, for example, polymers based on PVP (Antaron V216, V220 of GAF ChemiecalsCooperation), sodium polystyrene sulfonate (Flexan 130 of National Starch) or polyisobutene (Rewopal PIB 1000). Other film formers that improve the water resistance are in particular Unimer or Antaron types and Synchrowachse.

The proportion of film formers, in particular Unimer- or Antarontypen and Synchrowachse, is preferably less than 0, 1 wt.%, Preferably 0 wt.%, Based on the total mass of the preparation.

The water resistance of sunscreen products is determined in vivo on human skin in accordance with the COLI PA WR (Water Resistance) method of December 2005.

The SPF determination is made once on dry skin (static) and a second time after at least 2 x 20 minutes of watering and 15 minutes drying time (2x20 min = water resistant, 4x20 min = extra water resistant). The water resistance is confirmed if the value after washing, after deduction of the confidence interval, is greater than 50% of the SPF static.

The preparations according to the invention have furthermore been subjected to stress tests which prove the storage stability of the formulations according to the invention with a high proportion of UV filter.

Stress tests are carried out under different environmental conditions (heat, cold and room temperature) over a storage period of up to 360 days.

Subsequently, as set forth in the examples, hereinafter an organoleptic

Assessment of stability patterns. Furthermore, the pH and the viscosity or consistency are monitored over a period of up to 180 days.

High UV filter content means that the proportion of UV light protection substances comprises more than 10% by weight, based on the total mass of the preparation. The proportion is preferably selected in the range from 15% by weight to 40% by weight, in particular from 20 to 35% by weight. In the case of an SPF of the preparation of 30, the preparation advantageously comprises a UV filter substance content of 20 to 30% by weight, based on the total mass of the preparation. In the case of an SPF of the preparation of 50, the preparation advantageously comprises a UV filter substance content of 25 to 35% by weight, based on the total mass of the preparation.

At the same time, however, the preparations according to the invention have a good product sensor technology compared to the prior art and the UV light protection performance, determined according to Colipa, is not restricted.

Both the COLIPA ratio, as well as LSF and / or SPF of the invention

Preparations compared to preparations with the same or higher UV filter content are unchanged or even higher than in the same preparations without the

View thickener combination according to the invention.

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 at Civille, G.V. (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. These studies prove a light skin feeling without feeling sticky and the preparations according to the invention are absorbed quickly into the skin.

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 or Carbopol 2984 according to the invention preferably as a polyacrylate-based thickener to choose.

In particular, acrylates / C10-30 alkyl acrylate crosspolymer, as carbomer 3128 or pemulen TR1, should be used as the polyacrylate thickener.

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 acrylamide / ammonium acrylate copolymers are 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, such as PIB, for the purpose of better handling, in order, 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 used. That in addition to a Polyacrylamidverdicker are two

contain various polyacrylate thickeners in the preparation of the invention. 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.

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. Any customary carrier substances, adjuvants and optionally further active ingredients can be added to the preparation.

The preparation is preferably a hydrodispersion.

Optionally, the preparation can advantageously be added to 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

H yd roxy p ro py I strength P rophases r. 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 are methyl methacrylate crosspolymer,

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

Although the powder methyl methacrylate crosspolymer is also a polymer, but it has no thickening properties due to the chemical structure and therefore does not belong to the polyacrylate thickeners.

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 do not leave a greasy or sticky impression on the skin, have excellent skin compatibility and are furthermore surprisingly characterized in that they provide good sun protection performance and have no water-resistance on the skin without the addition of film formers.

A measure of the UV protection performance in the context of the present invention is, for example, the sun protection factor (SPF or SPF). UV filter substances based on triazine derivatives, which are the structural motif

are known per se and are described, for example, in EP-A-775 698, EP-A-0 878 469 and EP-A-1 027 881.

With regard to the C ₃ axis of the triazine core of these compounds, both symmetrical substitution and unsymmetrical substitution are conceivable. In this sense symmetrically substituted s-triazines have three identical substituents R ¹ , R ² and R ³ , while asymmetrically substituted s-triazine derivatives consequently have different substituents, whereby the C ₃ symmetry is destroyed. For the purposes of the present invention, "unsymmetrical" is always understood to be asymmetrical with respect to the C ₃ axis of the triazine base, unless something else is expressly mentioned.

Unsymmetrically substituted s-triazine derivatives according to the invention are also referred to below simply as triazine derivatives.

Triazine derivatives according to the invention are therefore, for example, those which are described in EP-A-775,698:

and or

The total amount of one or more of the UV filter substances, in particular those mentioned as particularly preferred UV filters, in the finished cosmetic or

dermatological preparations is advantageously selected from the range 15 wt .-% to 40% by weight, preferably from 20 to 35 wt .-%, each based on the total weight of the preparations.

The list of said conventional UV filter substances which can be used in the context of the present invention is of course not intended to be limiting.

The UV filters increase, increase the sunscreen of cosmetic or dermatological preparations. Although the preparations per se have a UV protection due to the UV filter contained, but this sunscreen by the addition of

Thickener combination increases without increasing the proportion of UV filters. The

Substances of the invention are referred to as boosters, SPF boosters due to their performance increase and the "increase" of sunscreen performance as a boosting or SPF boosting.

The preparations further advantageously comprise one or more

Skin moisturizing agent in a proportion of 1 to 10 wt.%, Preferably between 2 and 7.5 wt.%, Particularly preferably between 2.5 and 5 wt.%, Based on the total mass of the preparation.

Preferred humectant is glycerol. Further particularly preferred moisturizers are propylene glycols and butylene glycols.

The 1, 2 alkanediols, in particular 1, 2-pentanediol, 1, 2-hexanediol and 1, 2-octanediol, are beneficial skin moisturizer. The latter are preferably used 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.

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 sunbathing 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.

Advantageous moisturizers for the purposes of the present invention are, for example, glycerol, lanolin and its esters, lanolin alcohol, sorbitol, lactic acid and salts thereof,

Pyrrolidoncarboxylic acid and its salts and urea. Further humectants are, for example, polymeric moisturizers from the group of water-soluble and / or in Water swellable and / or water-gellable polysaccharides. Hyaluronic acid, chitosan and / or a fucose-rich polysaccharide, for example, which are filed in the Chemical Abstracts under the registry number 178463-23-5 and z. B. under the name Fucogel®1000 of the company SOLABIA SA is available.

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.

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, e.g. INCI name for an octamethylcyclotetrasiloxane having 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) and smaller proportions of heavier linear silicone compounds

such as. Dimethicones with siloxane units greater than 20 or so-called silicone gums (such as, for example, 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 preparations according to the invention feel light and non-sticky on the skin and penetrate quickly into the skin.
