Abstract

The invention relates to cosmetic or dermatological preparations which contain extracts of snow algae and one and several further substances which are suitable for skin protection.

Description

Contains cosmetic and / or dermatological preparations

Snow algae extract

The present invention describes cosmetic or dermatological preparations containing snow algae extracts to achieve skin protection.

Cosmetic or dermatological preparations that aim to protect the skin are in principle not new. In the past, cosmetic and dermatological compositions have been used several times to protect the skin, especially the human skin. However, there is still a need to improve or modify skin protection because of changing environmental conditions as well as users' living conditions and habits.

For example, the increased CO ₂ emissions into the atmosphere cause a climate change that is accompanied by an increase in temperature. This has an impact on human skin, which requires more protection and also changed protection.

In the course of progress, there is pollution of the environment, especially the air. These contaminants may be gaseous in the form of carbon dioxide, methane, halogenated and partially halogenated hydrocarbons and other gases, or may be particulate, e.g. in the form of soot particles. All of these contaminants come in contact with the skin and can cause irritation or even severe disorders. Again, this requires improved and / or altered skin protection.

The changed living conditions mean that many people, especially in Western countries spend a long time of the day indoors. In the cold season, these rooms are heated and the air in the room is therefore usually very dry. The skin reacts with dehydration. Improved skin protection is required.

Snow algae extracts are extracts of snow algae extracted from Chlamydomonas spec. can be won. These extracts can be obtained from snow algae grown by the process of 2-phase cryo-culture. After culturing, a total extract can be prepared by high pressure homogenization using empty liposomes. Simultaneous drying and application of the extract to a support material by fluidized bed drying can complete the preparation of the extract. The carrier material may for example consist of isomalt, lecithin, sodium benzoate, lactic acid and water in various proportions by weight. The snow algae extract may, for example, be in powder form and have the following composition:

Isomalt 92

Water 5.34

Chlamydomonas extract 2

Sodium benzoate 0.3 Lactic acid 0.2

Lecithin 0.16,

all data in% by weight.

The snow algae extracts obtained in this way are obtainable, for example, from the company Mibelle and have the name mibexol.

The snow algae are freshwater algae belonging to the genus Chlamydomonas. Today, about 350 species of snow algae are known, especially common is Chlamydomonas nivalis, a unicellular alga. The snow algae occur on snow and glacier surfaces in polar and alpine regions. Their mass increase is responsible for the green and red color of the snow; eg the blood snow. During the winter, the algae rest in the form of spores, often colored red, under the snow. In spring, the spores turn into green, UV light-sensitive algae, which migrate to the surface of the snow. There, with the help of photosynthesis, the necessary energy is gained and multiplication begins. When nutrient limitation occurs again sporulation, ie the formation of red spores. The red color stems from the incorporation of carotenoids (astaxanthin) for UV protection. The living conditions of the snow algae are extreme, the temperatures are low, the UV radiation is strong and nutrients are scarce. The snow algae must therefore feed on water, C0 ₂ , sunlight and minerals. The optimal growth temperatures are 0 to + 5 ° C. In order to survive under these conditions, snow algae undergo a number of adaptations, detectable by the presence of various secondary metabolites, such as pigments (including carotenoids, eg astaxanthin), biopolymers (jellies), antifreeze proteins, antifreeze glycoproteins, and osmotically active amino acids and sugars.

The use of Chlamydomonas extracts in cosmetic preparations has already been described in isolation.

According to the invention, the usual packaging suitable as they are used in cosmetics or dermatology application. For certain forms of preparation, however, it may be advantageous to keep separate components of the preparation according to the invention separately and to bring them together shortly before use. Then it is particularly advantageous for the purposes of the present invention to provide packaging materials which have a two-chamber technology.

Advantageously, for example, the so-called. Bag-on-valve systems, consisting of a valve which is hermetically sealed to a foil bag. The foil bag is optimally multi-layered with at least one or more barrier layers. The bag valve is hermetically sealed before being filled with an aerosol container (aluminum, tinplate or plastic).

In the so-called bag-in-can system, the bag is located in an aerosol container and is connected to the valve and the aerosol container when closing.

Described are such packaging in DE-20301831, EP-972923, EP-1061006 or EP-586295, which are hereby included in the disclosure of the present invention.

The container is preferably supplied with environmentally friendly propellant gases, such as nitrogen or noble gases, wherein the propellant gas between the bag and sealed aerosol container is, whereas the cosmetic is in the bag.

The mode of operation of the bag-in-can systems or bag-on-valve systems can be described as follows: the propellant surrounds the bag filled with the cosmetic. When the nozzle, the spray or application head of the system, is depressed, the pressure on the bag will cause the contents to leak in varying amounts depending on the diameter of the nozzle. For this purpose, the preparation contained in the bag must be matched to the packaging in order to achieve the correct output in terms of viscosity at a given can pressure. The advantage of the two-chamber technology (bag-in-can systems, bag-on-valve systems) is that no contamination and thus no air can penetrate into the bag under pressure.

The dispensing head optimally includes a closing mechanism at the exit opening which reduces potential contamination of the product between the valve opening and the exit opening.

The self-closing dispensing head can z. B. be executed as follows:

By actuating the applicator, an aerosol valve is opened, the product flows through a channel to the outlet opening. As it flows through the channel, the elastic element (eg made of a thermoplastic elastomer (TPE), polyethylene, polypropylene, polyoxymethylene (POM)) expands, which keeps the channel closed in the untreated state up to the outlet opening. Prerequisite for this is a higher dose pressure in relation to the ambient atmosphere.

When closing the aerosol valve, the pressure between the aerosol valve and the outlet is reduced until it is completely sealed. As a result of the decrease in pressure, the elastic element is lowered into the product-carrying channel, and the remaining contents are applied until the channel has been completely closed.

In this way, contamination of the remaining contents in the dispensing head is prevented by the ambient atmosphere until the next opening of the aerosol valve.

The selbstverschliessende dispensing head may also z. B. be carried out as follows:

By actuating the applicator, an aerosol valve is opened, an elastic membrane springs opposite to the product flow. An inseparable plug connected to the membrane follows this movement and the exit port / ring slit nozzle is opened.

When closing the aerosol valve, the product flow decreases. Due to the pressure drop, diaphragm and plug move to their original position and the outlet / ring slit nozzle is closed.

Also by this principle, the contents are optimally protected in the head.

The effectiveness of the snow algae extracts was proven in several series of tests.

In a cytotoxicity test, the MTT test, the compatibility of snow algae extracts was demonstrated. For this purpose, keratinocytes were incubated with various concentrations of snow algae extract for 12 hours. Subsequently, the cell vitality was determined by the MTT test. In the MTT test, a mitochondrial dehydrogenase in living cells cleaves the tetrazolium ring of the pale yellow substance MTT (3- (4,5-dimethylthiazolyl) -2,5-diphenyltetrazolium bromide). It produces dark blue formazan crystals, which are accumulated in intact cells. The cells are lysed and the crystals released. The amount of crystals formed is determined photometrically at 595 nm and is a direct measure of the number of intact cells. Figure 1 shows the results of treatment of HaCaT cells (spontaneous immortalized keratinocytes), NIH3T3 fibroblasts and mesenchymal stem cells (MSC) with snow algae extracts and determination of cell vitality. There is no toxic effect on snow algae extract treatment of these cell types.

The antioxidant activity of snow algae extracts was determined by two different test methods. The measurement of the antioxidant capacity is based on a redox reaction between a test substance, here snow algae extract, and copper II (Cu (II)). When the test substance is reducing, Cu (II) is converted to Cu (I). Cu (I) is detected by the addition of bathocuproine. The photometric measurement takes place at 490 nm. The results of this test are shown in FIG. 2a. The reducing power of snow algae extract at various concentrations becomes apparent.

The capacity of a substance to absorb oxygen radicals is determined in the ORAC (oxygen radical absorbance capacity) test. The ability of a test substance to inhibit the oxidation of a fluorophore, usually fluorescein, by a strong oxidant is determined. The strong oxidant is 2,2'-azobis (2-amidino-propane). The course of the reaction is monitored by measurements at 535 nm. As standard the substance Trolox is used. Trolox is a water-soluble vitamin E derivative and has a pronounced antioxidant capacity and is therefore used as a reference substance. The standard curve is obtained by plotting the various Trolox concentrations against the mean of the area determinations of two measurements for each concentration. For the evaluation, the net area under the curve (AUC) of the samples and the standard solutions in different concentrations is determined. The net area values are obtained from the difference of the sample area values or standard area values and the area value below the zero value. The determination of the zero value takes place without addition of sample or standard. The ORAC values of the samples are given as μηιοΙ Trolox equivalents per liter. The results of the ORAC test for snow algae extract are shown in Figure 2b. The upper part of the figure shows that snow algae extract has a good antioxidant power down to low concentration ranges (0.03%). To substantiate this data, comparisons were made with resveratol. Resveratol is a phytoalexin and belongs to the polyphenols. It was first isolated in 1963 from Japanese Knotweed. This substance has strong antioxidant properties. The results in the lower part of Fig. 2b show a good antioxidant activity for snow algae extract, but does not quite come close to the efficacy of resveratol.

Mutations of mitochondrial DNA (mtDNA) occur during the normal aging process. The most common mutation is a deletion of 4,977 bp, including the called common deletion. This mutation can be detected by a test using PCR (common deletion assay). Keratinocytes were grown and treated with snow algae extract (0.05%) for 48 hours. After replacing the cell culture medium with PBS solution, the cells were irradiated with UVB light (1.5 mJ / cm ² ). This was followed by a one-hour incubation in cell culture medium at 37 ° C. The cells were harvested, the DNA extraction was carried out with a QiagenKit. For the PCR 2-5 ng of DNA were used. Two deletions, the common deletion (CD) comprising 4977 bp, in a 630 bp band and the alternative deletion (AD) comprising 5148 bp in a 480 bp band were detected (FIG. 3a). As a standard, a 247 bp fragment was amplified. By means of the intensity of the deletion band, expressed as the ratio of CD band to the standard band, the protection against damage by UV light achieved by the snow algae extract can be determined (Figure 3b above). In the second part of the figure (Fig.3b below), the AD band is included in the evaluation. The intensity of the AD band is expressed as the ratio of the sum of CD band and AD band to the standard band. It is clear that snow algae extract protects against damage from UV light on a large scale.

Every living eukaryotic cell has a nucleus in which the genetic information is localized in the chromosomes. Before each cell division, the genetic information is doubled. Transcription of genetic information leads to the formation of mRNA, which is translated into the corresponding proteins (protein biosynthesis). Many environmental factors, especially modern ones, mean stress for the cells. For their protection, there is a growth stop. This growth arrest is characterized by an increase in the transcription rate of the GADD45A gene. GADD45A is the abbreviation for Growth arrest and DNA-damage-inducible protein alpha. Even after treatment with DNA-damaging substances, the transcription rate of the GADD45A gene is increased. The transcription rate of GADD45A can be detected by PCR reactions (Figure 4). Fibroblasts and keratinocytes were treated with 1% and 3% snow algae extract or ascorbate for 2 hours, respectively. Control cells were not treated. Subsequently, the cells were exposed to a stress factor in the form of H ₂ 0 ₂ (150 μΜ). At various times the cells were harvested and the RNA isolated. Starting from the RNA, cDNA was synthesized which served as template for the PCR. As primers for the PCR, those specific for the GADD45A transcript were used. The PCR products were separated in an agarose gel and quantified with the Geliance 200 Imaging System (Perkin Elmer). The amplification band of the analyzed transcript was normalized with the amplification band of a standard 18S transcript. The values thus obtained were indicated as percentages in FIG. The untreated controls corresponded to 100% values. In fibroblasts, no increase in GADD45A transcripts is observed under control conditions. After the stress treatment, more GADD45A transcripts are detectable in the cells treated with snow algae extract or with ascorbate than in the control cells. This means that under stress conditions snow algae extract in a concentration of 3% causes an increased rate of GADD45A transcripts (58%) and thus increases the protection for the cells. In the keratinocytes, the non-stressed, untreated cells also showed an increased transcription rate of GAdd45A after exposure to snow algae extract. Transcription is significantly enhanced (79%, in 3% snow algae extract) under stress conditions. This shows that snow algae extract is capable of activating protective mechanisms in skin cells, especially under stress conditions. In another series of tests sirtuin transcripts were detected. Sirtuins are enzymes that deacetylate histone proteins. As a result, lysine residues are released and the nitrogen atom in the amine residue of this amino acid condenses more strongly with the DNA. As a result, transcription processes are disturbed or prevented. In addition, sirtuins also show ADP-ribosyltransferase activity, and in addition to the histones, a number of other proteins are also being modified, demonstrating an influence on cell aging and attempts to detect sirtuin transcripts However, primers for the detection of sirtuin transcripts in the PCR reaction were specific for sirtuin 1 (sirt 1) and sirtuin 6 (sirt6), respectively, and the evaluation and presentation were carried out in the same way As described for GADD45A, under stress conditions triggered by H ₂ O ₂ , the transcription rate in fibroblasts incubated with snow algae extract increased by 18% and sirtuin 6 by 18% and sirtuin 6, respectively, by 28% compared to untreated cells the transcription rate of sirtuin 1 by 14% and of sirtuin 6 by 27% by the action of snow algae extract compared to unbehan damaged cells. In mesenchymal stem cells under H ₂ 0 ₂ stress conditions (up to 450 μΜ) no significant reduction in sirtuin gene expression was observed. Overall, the snow algae extract triggered a slight increase in sirtuin gene expression, regardless of the severity of the stress. The influence of snow algae extract in three different cell types has been shown to influence sirtuin gene expression.
