Definitions
- the present invention relates to preparations for the care of stressed or slightly injured irritated skin.
- Known skincare preparations usually contain oils or waxes which occlusively cover the skin and thus cover light lesions / fissures such as occur during shaving or in babies in the diaper area. The leakage of blood and wound exudate is thus physically stopped and hemostasis naturally occurs after some time.
- Alaunkynite For faster attenuation or stopping of the escape of blood and wound exudate of the micro-lesions of the skin occurring during shaving, there are so-called Alaunkynite with which the wound is treated.
- Alum has a strong astringent effect, which leads to a contraction of the tissue and thus to stopping the bleeding.
- alum irritates the skin, so that the application is unpleasant, sometimes painful.
- the diaper area is not limited to the regions that come in contact with the excrement.
- the diaper area also includes the skin areas, which are covered by cuffs or elastic bands of diapers and can be scoured by them.
- the object of the present invention is therefore to avoid the disadvantages of the prior art and to find a low-cost substance of plant origin, which is stable in skin care preparations and leads to the reduction of the time until the onset of hemostasis.
- the present invention therefore relates to skin care preparations, in particular oil-in-water emulsions, hydrogels or aqueous gels which have an effective concentration of ellagic acid.
- Ellagic acid is a polyphenol having a molecular weight of 338.2 g / mol and the following structure:
- ellagic acid is found in significant concentrations of up to 1% in many plants and woody plants. These include raspberries, pomegranates, strawberries, blackberries, walnuts and many other fruits and nuts. Together with gallic acid, it is also found in rose plants. By acid hydrolysis, the ellagtannin decomposes, inter alia, in ellagic acid. In water, ellagic acid is only sparingly soluble, but it dissolves in ethanol, dilute alkalis, and pyridine.
- Ellagic acid is also known as a component of diagnostics for the investigation of the intrinsic pathway of blood clotting. It promotes fibrin formation, assuming that ellagic acid is responsible for surface activation. (T.Exner & K. A. Rickard, Thromb. Res. 26 (1982), 83-89; A. Girolami et al., Blood 27 (1966), 93-102).
- the poor solubility of the ellagic acid causes the addition of the ellagic acid in the preparation of the skin care preparation as a suspension. Even when homogenizing the ellagic acid dissolves only to a small extent and is at least partially particulate in the finished skincare preparation.
- the sources of ellagic acid are advantageously and preferably natural sources.
- the ellagic acid is prepared from natural sources, in particular from purified extracts of ellagic acid-containing plant parts, in particular from fruits.
- the extraction of active ingredients from plant parts has been familiar to the expert for centuries. Usually, the extraction is carried out with polar solvents such as ethanol, acetone or ethyl acetate with subsequent hydrolysis and filtration.
- polar solvents such as ethanol, acetone or ethyl acetate with subsequent hydrolysis and filtration.
- the production of pomegranate extracts is described in MN Aslam et al. (J. Ethnopharmacol., 103 (2006), 311-318) and can be transferred to other plant nutrient-containing plant material.
- extracts or the ellagic acid purified therefrom are commercially available, for example from Wagott (Chengdu / China), Ingredientrade Europe (New York / USA) or AMC / Premium Ingredients (
- ellagic acid obtained from pomegranates is particularly advantageous for the blood and secretion-calming effect.
- the coagulation process is accelerated compared to pure, synthetically produced ellagic acid.
- Ellagic acid is characterized by a very poor solubility in water, so that the effect depends very much on the free surface. To produce the largest possible surfaces it is therefore within the meaning of the invention to treat the ellagic acid-containing suspensions prior to addition with ultrasound in order to achieve a finer distribution as possible below 5 microns.
- the skin care preparation according to the invention is preferably an O / W emulsion or an aqueous gel.
- the content of skin care preparations containing ellagic acid should be between 0.001 and 0.1% by weight, based on the total weight of the preparation, in particular between 0.01 and 0.05% by weight.
- a very particularly advantageous embodiment of the skin care preparations according to the invention are sprayable skin care preparations which can be applied to the skin without heavy rubbing.
- a particular embodiment of these sprayable preparations can be used similar to a spray plaster.
- Sprayable skin care preparations according to the invention should have a viscosity of less than 5,000 mPas, in particular less than 2,500 mPas.
- the skin care preparation contains microbicides, in particular bactericides, virucides, fungicides or antibiotics, and thus the regeneration of the skin can proceed without problems. It is also possible that the skin care preparation of the invention contains substances that have skin-moisturizing properties, such. As diols and / or polyols, urea, hyaluronic acid or glyceryl glucose, or substances with filtersuitn- properties contains such. As panthenol, creatine, zinc, vitamin C or vitamin E.
- the powdery substances were suspended in phosphate buffered saline (PBS) at a concentration of 3.4 mg / ml (10 mmol / l) and used as a finely dispersed suspension either directly or after sonication (sonic bath, in ice for 30 min). Thereafter, the suspensions were diluted with PBS 1: 100 to a concentration of 34 ⁇ g / ml (0.1 mmol / l) of ellagic acid, based on pure ellagic acid.
- PBS phosphate buffered saline
- the test is carried out in accordance with ISO 10993-4, part B3, with citrated blood (CB).
- Thromboelastography is a global assay for quantifying blood clotting of whole blood (J.A. Caprini et al., 'Perspectives on thromboelastography', Semin Thromb, Hemost 21 (Suppl. 4, 1995), 91-93).
- the main measurement parameter is the clotting time: the time to fibrin clot formation. Hemostatic substances shorten the fibrin formation time.
- the starting suspension of the ultrasound-treated ellagic acid (10 mmol / l) described in Example 1 was diluted with the skincare preparation 1:10 to a concentration of 338 ⁇ g / ml (1 mmol / l). To ensure a good distribution, the batch was mixed for about 1 min with a vortex shaker.
- the clot formation time was reduced to 50% of the control value (citrated blood with PBS) by pomegranate ellagic acid doping (A3). Only a small reduction to 90% of the control value was found with the corresponding pure, synthetic ellagic acid ( Figure 3).
- the above-described ellagic acid-doped skincare preparations were examined by means of thromboelastography. The corresponding skincare preparation was mixed with 2.8 ml of citrated blood, swirled, and a sample of the test piece in the thromboelastograph was examined. The clot formation time was reduced to 28% by doping with pomegranate ellagic acid (A3) and only 91% with pure synthetic ellagic acid (B3) compared to CB + PBS ( Figure 4).
- Figures 1 to 4 graphically reproduce the experimental results of Examples 1 and 2.
