Definitions

  • the present invention relates to a process for the preparation of dermatological and cosmetic preparations with pronounced lamellar structures using hydrogenated phosphatidylcholine.
  • DMS Dermata Membrane Structure
  • the lamellar structures correspond to the skin physiology and serve the skin to protect against the ingress of external substances and regulate the transepidermal water loss through the skin.
  • lamellar structures The formation of the lamellar structures is dependent on the geometric packing factors, such as the volume of the fatty acid chains, the critical chain length, and area occupied by the headgroup (Israelachvili, JN In Intermolecular and Surface Forces, 2nd Ed., Jovanovich, HB; London 1994). This means that not every amphiphilic substance can form lamellar structures or membranes.
  • the best-known lipid capable of forming such lamellar structures is phosphatidylcholine (PC), also part of human cell membranes. Phosphatidylcholine is found in a high concentration in soya lecithin.
  • phosphatidylcholine especially the hydrogenated one, shows a pronounced barrier-stabilizing effect.
  • the skin barrier is stabilized by PCH-containing preparations with lamellar structure in such a way that after application of the transepidermal water loss (TEWL) changes only slightly when external substances act on the skin.
  • TEWL transepidermal water loss
  • the protection thus obtained is also characterized by a high water resistance and welding strength.
  • the use of hydrogenated phosphatidylcholine is highly desirable for cosmetic or dermatological preparations.
  • the object of this invention was to develop a method with which it is possible, using the known since 1995 ingredients for membrane structure creams, in particular using hydrogenated phosphatidylcholine, stable cream bases for topical application to produce a qualitatively and quantitatively pronounced lamellar Have structure and in which active ingredients and biological materials at room temperature, in one operation open-minded (ie detached from their cells and agglomerates split) and can be stored directly between the forming lamellar structures.
  • Another important advantage of the inventive production process is the possibility of producing very small units of 20-50 ml with individual formulations adapted to the skin type.
  • Galenic preparations for cosmetic or dermatological products consist predominantly of a water phase and a fat phase. Both phases are usually mixed or emulsified with the aid of appropriate emulsifiers and with the use of high-speed stirrers, mixers or the like.
  • the inner phase is distributed as finely as possible in the outer phase, so that a sufficient stability and storage time is achieved.
  • a sufficient amount of emulsifiers and preservatives is also necessary to ensure a practical storage time of the products.
  • Emulsifiers and preservatives are, however, substances which pollute the skin and are often triggers of allergies.
  • a cosmetic or dermatological preparation can be produced in less than one minute, without chemical emulsifiers and at room temperature, even using temperature-sensitive, biological materials .
  • preemulsions can also be used, which are then mixed in a second step at any later time with additional dermatological and / or cosmetic agents, for example with biological cell materials, blood components such as blood plasma or blood serum, vegetable oils, vitamins, peptides , Hyaluronic acids, plant extracts, fruit acids and the like.
  • the ultrasound introduction described above can already take place during the production of the pre-emulsion and / or after the addition of the additives in a second operation.
  • the introduction of the ultrasound in the pre-emulsion has the purpose of hydrogenating with the aid of the present Membraniipide, preferably phosphatidylcholine and / or not hydrogenated to produce fine oil droplets in the range of 5-500nm, preferably in a size of 50-250 nm, which then in the described second step, in the introduction of the additives, form particularly fine lamellar layers.
  • the aid of the present Membraniipide preferably phosphatidylcholine and / or not hydrogenated to produce fine oil droplets in the range of 5-500nm, preferably in a size of 50-250 nm, which then in the described second step, in the introduction of the additives, form particularly fine lamellar layers.
  • the monohydric and / or polyhydric alcohols are preferably methyl, ethyl, propyl or isopropyl alcohol, phenoxyethanol, pentylene, butylene or hexylene glycol. definitions
  • Ultrasound machines are available in different designs and services.
  • devices are needed which provide sufficient energy needed to disperse a liquid phase (fat phase) into small drops in a second phase (stable phase).
  • imploding cavitation bubbles cause intense shockwaves in the liquid and as a result, generate very high velocity liquid jets.
  • the newly formed droplets of the dispersed phase align themselves immediately with the help of the membrane lipids and form lamellar structures with a thickness of a few nanometers, with the lipophilic phases and the hydrophilic phases then alternatingly stacking up.
  • the vibration amplitudes of the introduced ultrasound preferably move from about 1 to 200 microns, while the high pressure and low pressure cycles between 15,000-30,000 cycles / sec, preferably at 20,000 cycles / sec. be.
  • the shear forces mechanically close the cell envelope and thereby increase the exchange of material.
  • the membrane lipids hydrogenated phosphatidylcholine
  • the lamellar layers in which the intracellular material is spontaneously incorporated are formed.
  • Organic cell material in this patent means materials which have been dissolved out of biological cells. These may be of plant origin, e.g. Algae and / or animal or human origin. They may be derived from tissues and / or body fluids such as blood and / or from microorganisms such as yeasts or bacteria.
  • MS concentrate prepared with hydrogenated phosphatidylcholine, neutral oil and homogenized via a high-pressure homogenizer
  • neutral oil medium-chain triglycerides
  • the components are placed in a glass container, which is closed and placed in the ultrasound machine, which introduces the ultrasound from the outside through the wall. After just one minute, the formation of a homogeneous cream mass is evident.
  • the components are placed in a glass container, which is closed and placed in the ultrasound machine, which introduces the ultrasound from the outside through the wall. After just one minute, the formation of a homogeneous cream mass is evident.
  • the components of the pre-emulsion are heated to 70 ° C and charged with ultrasound until a homogeneous milk is formed with a droplet size of 50-200 nm.
  • This pre-emulsion can be stored under exclusion of air for several months.
  • the components are mixed, resulting in the formation of fine, lamellar layer structures directly from the nanoparticles of the pre-emulsion, which is indicated by a significant increase in viscosity, while the added active ingredients, such as oils, blood components and hyaluronic acid intercalate between the lamellar layers.
