Description

FIELD OF THE INVENTION

The present invention is related to a composition comprising vegetable essence and/or ingredients and/or active agents, carbohydrate and phospholipid, a method for production of such a composition and the pharmaceutical, dietary or cosmetic application of such a composition.

BACKGROUND OF THE INVENTION

Vegetable resources are of continuously increasing importance for the preparation of pharmaceutical, dietary or cosmetic applications. The demand for purely natural models is of increasing importance. Vegetable resources, particularly vegetable essences with active agents are not always stable and in most of the cases difficult to insert into a model.

The document U.S. Pat. No. 5,387,415 discloses the production of Aloe vera juice pellets by seeping said juice with with collagens into liquid azote at −196° C. The method is very onerous at high energy consumption. A similar method is taught in U.S. Pat. No. 5,401,502.

The document U.S. Pat. No. 5,387,415 discloses bisabolol nanoparticles, pre-emulsion with lecithin in a high pressure homogenizer, subsequently spray dried by means of starch and maltodextrin. It has always to be worked with a starch dye. The products are spray dried. Many vegetable extracts and their ingredients are very sensitive and may be decomposed or exhausted during spray drying. Said decomposition or exhaustion ought to be avoided.

The document U.S. Pat. No. 5,180,713 discloses the production of pharmaceutical liposomes in organic solvents in the presence of cryoprotectants, such as sugar. It has to be worked in organic solvents, being difficult to remove from the end-product and being unwanted in natural products.

The document U.S. Pat. No. 6,534,087 discloses foamed pills of active agents; lecithin and maltodextrin. Measured powders or granules with stable characteristics can't be produced like that.

The document US 20040234673 discloses a composition with an amorphous carbohydrate phase, a crystalline phase and a third phase, selected from one or more substances made of aroma, volatile substances and substances sensitive towards external impacts, the third phase being dispersed by means of emulsifiers in the other two phases. Any extrusion of this composition is carried out at high temperatures. By working at higher temperatures the ingredients of the vegetable extracts are decomposed and their intended activity can not be provided.

The patent applications EP 209037, EP 209038, EP 275005, EP 275224, EP 283713, EP 300282, EP 304603, EP 441279, EP 464297, EP 1390008, EP 1837030, EP 1844785 disclose stabilization of vegetable extracts by complex formation of the active agents with phospholipids. For this work has to be done in solvents, such as methylene chloride or methanol. This mode of operation is very elaborate and requests the use of questionable solvents.

The problems of formulation and the limited stability during transport and storage of the compositions of the state of the art are due to the selection of their components, particularly the quality of the lecithins with shares of phosphatidylcholine of less than 15%.

Phospholipid-fractions are preferred with a share of phosphatidylcholin of 40-80%.

Lecithin is composed of neutralipids, glycolipids and phospholipids. The Phospholipids are composed of e. g. phosphatidylcholine (PC), phosphatidylethanolamin (PE), phosphatidylinositol (PI), phosphatidylserin (PS), lysophosphatidylcholine (LPC), lysophosphatidylethanolamine (LPE), lysophosophatidylinositol (LPI) usw. (A. Wendel Lecithin, Kirk-Othmer Encyclopedia of Chemical Technology, Fourth Edition, Volume 15; Willem van Nieuwenhuyzen, Fett/Lipid 99 (1997, Nr. 1, S10-14, Willem van Nieuwenhuyzen, Eur. J. Lipid Sci. Technol 2008, 110, 472-486. Customary lecithin contains about. 12-15% phosphatidylcholine. De-oiled lecithin, as well called pure lecithin, contains 20-25% phosphatidylcholine. Phospholipid-fractions with shares of 30 to 100% phosphatidylcholine may be produced by fractioning with ethanol. Customary products enriched with phosphatidylcholine are e.g. phospholipids of soy as e.g. Lipoid S 20 (approx. 20-24% PC, 16-22% PE), Lipoid S45 (45% PC, 10-18% PE), Lipoid S75 (70% PC, 7-10% PE), Lipoid S80 (75% PC, 7% PE), Lipoid S100 (>94% PC), phospholipon 20 (about 20-24% PC, 16-22% PE), phospholipon 50 (approx. 45-50% PC), phospholipon 85G (>80% PC), phospholipon 90G (>95% PC) or phospholipids of rape, such as e. g. Lipoid R20 (approx. 20-24% PC, 16-22% PE), Lipoid R75 (70% PC, 7-10% PE), Lipoid R45 (45% PC, 10-18% PE), Lipoid R75 (75% PC, 7% PE), Lipoid R80 (75% PC, 7% PE), Lipoid R100 (>94% PC) or soy phospholipids from genetically non modified (non GMO) soy beans such as e. g. Lipoid P45 (45% PC, 10-18% PE), Lipoid P75 (75% PC, 7% PE) , Lipoid P100 (>94% PC).

Sugar (mono-, di-, or polysaccharides) like manit (mannitol), glucose (dextrose), trehalose (mykose), saccharose (sucrose), lactose (milk sugar), fructose (levulose), mannose, ribose, galactose, fructose, rhamnose, lactulose, maltose, raffinose, dextrin or maltodextrin are used for carbohydrates. Mannit, glucose, trehalose are preferred and particularly preferred is maltodextrin.

The inventive composition is produced by dissolving or dispersing the elements simultaneously or subsequently at room temperature in water and by homogenizing in customary devices, such as for example by a microfluidizer, 1-3 cycles, after that filtration or sterile filtration, e.g. by a 2-8 μm filter-candle and subsequently by freeze- or vacuum-drying gently at −30° C. to +45° C. The dried product may be ground to the wanted grain size in suitable devices with an orifice diameter of 0.5-1.5 mm.

Liposomal compounds may be produced at redispersing.

The dried composition is stable for transport and storage and easy to work into cosmetic, dietary and pharmaceutical formulations. Advantages are the good solubility, the wettability of the active agent is improved, the characteristics at dispersion of the active agents are optimized, the stability of the active agent against environmental impacts is improved, odor and taste of the active agent is optimized.

During treatment of the new composition in cosmetic, dietary and pharmaceutical formulations the best bio-disposability is achieved.

Formulations are e. g. oral, such as powders, granules, pills, capsules and topic preparations such as creams, lotions, etc. by adding the customary additives.
