This invention relates to microfluidized liposomes which contain cosmetic and/or dermopharmaceutical agents wherein these liposomes are coated with a cationic polymer which conserves the positive charge necessary for an effective adsorption of the liposomes in natural or synthetic fibers. The release of the liposomes and therefore the cosmetic and/or dermopharmaceutical agents which contain these liposomes is carried out through the standard methods of pressure, skin pH, friction, osmosis or heat.
This invention refers to liposomes with cosmetic and/or dermopharmaceutical ingredients for the care of the skin, scalp and/or hair. The cationic polymers on the surface of the liposomes allow their effective linking to the fibers of the textile material.
The preparation of textile materials with chemical products linked to them has been extensively studied to provide textile materials with cosmetic and/or dermopharmaceutical purposes, i.e. textile materials which release cosmetic and/or dermopharmaceutical agents in contact with the skin. However, there is the need in the prior art for the aforementioned cosmetic and/or dermopharmaceutical active ingredients to have a greater permanence on the textile material than at present, since the delivery systems which contain these active ingredients are separated from the textile material after a few washes.
Surprisingly we have found that certain cationic polymers bound to liposomes link to the surface of the textile material on several points forming a net or mesh-like structure. The liposomes coated with cationic polymers, which we propose in this invention are a solution open to any cosmetic and/or dermopharmaceutical active ingredient and have sufficient stability to remain attached to the textile material, both natural and synthetic, after several washes.
This invention relates to liposomes which contain cosmetic and/or dermopharmaceutical active ingredients and/or adjuvants, and which are linked to cationic polymers, wherein these polymers form a network over the surface of the textile material when they are brought into contact with textile material. This network on the surface of the textile material enables a more effective linking of the liposomes to the textile material than in the case of the liposomes known in the prior art.
Liposomes are a commonly used solution which prolongs the period of availability of an active agent. The material on the wall of the liposome presents a resistance and thermal stability that are such that the liposome is not destroyed under storage conditions, but the mechanical release of the encapsulated substances is enabled under light pressure action, or thermal release at a temperature of 35 to 220° C. Another possibility consists of the liposome wall becoming semi-permeable in its properties through its modification such as from pressure, friction or heat.
In this invention the term “liposome” relates to an approximately spherical aggregate formed by at least a double layer or bilayer of at least one phospholipid wherein the layers are very close and the apolar regions of each layer face the apolar regions of the other lipid layer, and thus the polar regions of the phospholipids form the internal and external face of the double layer or bilayer. The liposomes of this invention can have just one bilayer and are structured like unilaminar liposomes, or they can have from 2 to 6 bilayers, concentric or non-concentric, of lipids, preferably from 2 to 4 concentric bilayers, and will then be organized as multilaminar liposomes like onions, or can have from 2 to 6 bilayers and be organized like unilaminar liposomes which are comprised of 1 to 5 smaller unilaminar liposomes. The liposomes in this invention present a nucleus which can contain a series of hydrophilic cosmetic and/or dermopharmaceutical active ingredients, and at least a lipid bilayer which can contain hydrophobic cosmetic and/or dermopharmaceutical active ingredients.
In a particular embodiment, the phospholipid of the liposomes of this invention is a natural or synthetic phosphoglyceride and is preferably selected from the group formed by phosphatidylserine, phosphatidylinositol, phosphatidylethanolamine, phosphatidylcholine, phosphatidic acid, phosphatidylglycerol, diphosphatidylglycerol, phosphorylcholine, cardiolipin, their fatty acid esters, hydrogenation products and mixtures thereof, such as and not restricted to natural lecithins such as that from an egg, soy or sunflower. Among the fatty acids are found, for example and not restricted to, stearic, palmitic, oleic, myristic, lauric acid and any saturated or unsaturated fatty acids known in the prior art. Preferably, the phospholipids used are phosphatidylcholine, phosphatidylethanolamine and phosphatidylinositol.
In a particular embodiment, the liposomes are mixed liposomes formed by one or more phospholipids and one or more homogeneously distributed surfactants in each of the double layers or bilayers and with the aforementioned described structures for the liposomes. In particular, the surfactant of these mixed liposomes is selected from the group formed by non-ionic surfactants, amphoteric surfactants, anionic surfactants, cationic surfactants and mixtures thereof. Preferably, the surfactants are non-ionic surfactants and/or amphoteric surfactants, more preferably they are selected from the group formed by alkylglycosides with an alkyl group which has from 6 to 24 carbon atoms, alkylmaltosides with an alkyl group which has from 6 to 24 carbon atoms, ethoxylated alkylphenols with an alkyl group which has from 6 to 24 carbon atoms and from 5 to 30 units of ethylene oxide, alkyl phenyl polyoxyethylene ethers with an alkyl group which has from 6 to 24 carbon atoms, saturated or unsaturated fatty alcohols with an alkyl group which has 8 to 24 carbon atoms, poloxamers, polysorbates, sorbitan esters, polyethylene glycol fatty acid esters, ricin oils, fatty alcohol and polyoxyethylene ethers, fatty acid alkanolamides, amine oxides, alkyl betaines with an alkyl group which has from 6 to 24 carbon atoms, acyl amido betaines, alkyl sulfobetaines with an alkyl group which has from 6 to 24 carbon atoms, glycine derivatives, digitonin and mixtures thereof. More preferably they are selected from the group formed by octyl glucoside, decyl glucoside, lauryl glucoside, octyl fructoside, dodecyl maltoside, decyl maltoside, nonoxynol-9, polyethylene glycol p-(1,1,3,3-tetramethylbutyl)phenyl ether, palmityl alcohol, oleyl alcohol, poloxamer 188, poloxamer 407, polysorbate 20, polysorbate 60, polysorbate 80, polyethylene glycol stearate 40, polyethylene glycol stearate 50, polyethylene glycol stearate 100, polyoxyethylene stearyl ether, polyoxyethylene lauryl ether, cocamide monoethanolamine, cocamide diethanolamine, cocamide triethanolamine, lauramide diethanolamine, lauramide monoethanolamine, cocamidopropylamine oxide, decyl betaine, dodecyl betaine, tetradecyl betaine, cocoyl betaine, cocamidopropyl betaine, cocamidopropyl hydroxysultaine, cocoyl amidoethyl N-2-hydroxyethylglycinate and N-cocoyl amidoethyl 2-hydroxyethylcarboxyglycinate and mixtures thereof.
In another particular embodiment, the cationic polymers bound to the liposomes are natural or synthetic polymers, for example, cationic derivatives of cellulose, such as quaternized hydroxyethylcellulose, which can be acquired under the name Polymer JR 400™ by Amerchol, cationic starches, copolymers of diallylammonium and acrylamide salts, quaternized vinylpyrrolidone/vinylimidazole polymers such as Luviquat™ (BASF), condensation products of polyglycols and amines, polyquaternium polymers and copolymers, polymers named Merquats of polyquaternium-6, polyquaternium-7; polyquaternium-16, polyquaternium-10, polyquaternium-4 copolymers, dicocoylethylhydroxyethylammonium, graft copolymers with a cellulose backbone and quaternary ammonium groups, quaternized collagen polypeptides such as lauryldimethylammonium hydroxypropyl hydrolyzed collagen (Lamequat™ by Grünau), quaternized wheat polypeptides, polyethylenimine, cationic silicone polymers such as amodimethicone or silicone quaternium-22, adipic acid and dimethylamino hydroxypropyldiethylenetriamine copolymers (Cartaretine™ by Sandoz), copolymer of dimethyldiallylammonium chloride and acrylic acid (Merquat™ 550 by Chemviron), cationic chitin derivatives such as chitosan and its derivatives, condensation products of cationic dihalogen alkylene such as dibromobutane with bisdialkylamines such as bis-dimethylamino-1,3-propane, derivatives of cationic guar gum such as guar-hydroxypropyltriammonium, Jaguar™ CBS, Jaguar™ C-17, Jaguar™ C-16 by Celanese, quaternary ammonium salt polymers such as Mirapol™ A-15, Mirapol™ AD-1, Mirapol™ AZ-1 by Miranol, quaternized polysaccharide polymers from natural derivatives such as agar, cationic proteins selected from among gelatin, gum arabic; cationic polymers from the group formed by polyamides, polycyanoacrylates, polylactides, polyglycolides, polyaniline, polypyrrole, polyvinylpyrrolidone, amino silicone polymers and copolymers, polystyrene, polyvinylic alcohol, polystyrene and maleic acid anhydride copolymers, methyl vinyl ether, epoxy resins, and styrene and methyl methacrylate copolymers; dimethylamino methacrylate, polyacrylates and cationic polymethacrylates such as Eudragit™ RL 30 D by R{right arrow over (o)}hm; derivatives of polyamine optionally substituted by the derived members of polyethylene glycol; polyamine acids under pH conditions wherein they are cationic; polyethyleneimine; quaternized derivatives of polyvinylpyrrolidone (PVP) and hydrophilic urethane polymers, as well as any mixture of the aforementioned cationic groups.
The liposomes of this invention which contain cosmetic and/or dermopharmaceutical active ingredients and/or adjuvants can be applied to the natural or synthetic fibers of textile materials before or after manufacture. In this invention textile materials are understood to be fabrics, non-woven fabrics, garments and medical devices. Examples of fabrics, non-woven fabrics, garments, medical devices and means for immobilization of liposomes can be found in the literature and are known in the prior art (“Impregnating Fabrics With Microcapsules”, HAPPI May 1986; Int. J. Pharm. 2002, 242, 55-62; “Biofunctional Textiles and the Skin” Curr. Probl. Dermatol. 2006 v.3; J. Cont. Release 2004, 97, 313-320). Preferred means for immobilizing liposomes in textile materials are carried out through application using washing agents or the use of sprays without needing to soak the textile materials. Surprisingly this invention provides a considerable improvement on the binding of liposomes to the natural or synthetic fibers of the surface of the textile material during a prolonged period due to the network structure that the cationic polymers form on the textile material in relation to the liposomes bound to cationic monomers known in the prior art. The natural and/or synthetic fibers can be wool, cotton, silk, nylon fibers, cellulose or polyester, among others. Among the textile materials the preferred woven fabrics, non-woven fabrics, garments and medical devices are bandages, gauzes, t-shirts, socks, tights, underwear, girdles, gloves, diapers, sanitary napkins, dressings, bedspreads, wipes, hydrogels, adhesive patches, non-adhesive patches, micro-electric patches and/or face masks.
By means of the use of textile materials with adsorbed liposomes, the cosmetic and/or dermopharmaceutical active ingredients and/or adjuvants contained in the liposomes can be transferred to the skin, scalp and/or hair, after the skin, scalp and/or hair have been brought into contact with the liposome, through mechanical pressure, friction, osmosis or heat. In practice, the liposomes of the invention either due to biodegradation of the linking system to the textile material or due to friction between the textile material and the body, or due to body moisture or due to the body temperature, release the cosmetic and/or dermopharmaceutical active ingredients and/or adjuvants. The resulting phospholipids and the cosmetic and/or dermopharmaceutical active ingredients and/or adjuvants form a fine film on the surface of the textile materials which facilitates contact with the skin, scalp and/or hair and subsequently the transfer of the active ingredients and/or adjuvants through mechanical processes such as friction.
In addition, the cationic polymers bound to the liposomes modify their structure making them more flexible, which also allows the liposomes to cross or penetrate the skin, scalp and/or hair with greater ease, thus increasing the penetration of the cosmetic and/or dermopharmaceutical active ingredients and/or adjuvants.
Furthermore, if the liposomes of this invention undergo micro-fluidification, which allows homogenization of the liposomes through high pressure, smaller sized liposomes are obtained which affords them greater stability and consistency in comparison with the liposomes which have not undergone micro-fluidification.
In particular, the cationic polymer has positive charges which electrostatically interact with the phosphate group of the phospholipids which form the lipid membrane of the liposomes. Therefore, the same cationic polymer can interact with several liposomes at once forming a framework or network of liposomes whose overall charge is positive and which are linked to the surface of the textile materials at several points.
Cryomicroscopy and laser light scattering LLS assays show that this framework or network includes several liposomes within the same cationic polymeric network where the size of the cationic polymer is in the region of 600-1700 nm, in comparison with the size of the liposomes which are smaller or equal to 300 nm, in particular, smaller than 200 nm.
According to another aspect of this invention, the inside of the liposomes contains cosmetic and/or dermopharmaceutical active ingredients and/or adjuvants. In particular, the cosmetic and/or dermopharmaceutical active ingredients and/or adjuvants for the treatment and/or care of the skin, scalp and/or hair are selected, for example and not restricted to, the group formed by surfactants, humectants or substances which retain moisture, emollients, moisturizers, agents stimulating healing, coadjuvant healing agents, agents stimulating re-epithelialization, coadjuvant re-epithelialization agents, agents stimulating the synthesis of dermal or epidermal macromolecules, firming and/or redensifying and/or restructuring agents, cytokine growth factors, agents acting on capillary circulation and/or microcirculation, anti-glycation agents, free radical scavengers and/or anti-atmospheric pollution agents, reactive carbonyl species scavengers, 5α-reductase inhibiting agents, lysyl- and/or prolyl hydroxylase inhibiting agents, defensin synthesis-stimulating agents, bactericidal agents and/or bacteriostatic agents and/or antimicrobial agents and/or germicidal agents and/or fungicidal agents and/or fungistatic agents and/or germ-inhibiting agents, anti-viral agents, antiparasitic agents, antihistaminic agents, NO-synthase inhibiting agents, desquamation agents or keratolytic agents and/or exfoliating agents, comedolytic agents, anti-psoriasis agents, anti-inflammatory agents and/or analgesics, anesthetic agents, anti-wrinkle and/or anti-aging agents, cosmetic deodorants and/or absorbent and/or body odor masking deodorants, antiperspirant agents, perfuming substances and/or perfumed oils and/or isolated aromatic compounds, anti-oxidizing agents, agents inhibiting vascular permeability, hydrolytic epidermal enzymes, whitening or skin depigmenting agents, agents inhibiting sweat-degrading enzymes, agents capable of filtering UV rays, agents which stimulate or regulate the differentiation of keratinocytes, anti-itching agents, agents which stimulate or inhibit the synthesis of melanin, propigmenting agents, self-tanning agents, agents stimulating the proliferation of melanocytes, liquid propellants, vitamins, amino acids, proteins, biopolymers, gelling polymers, skin relaxant agents, agents capable of reducing or treating bags under eyes, agents for the treatment and/or care of sensitive skin, astringent agents, agents regulating sebum production, anti-stretch mark agents, lipolytic agents or agents stimulating lipolysis, venotonic agents, anti-cellulite agents, calming agents, agents acting on cell metabolism, agents to improve dermal-epidermal junction, agents inducing hair growth or hair-loss retardant agents, body hair growth inhibiting or retardant agents, heat shock protein synthesis stimulating agents, muscle relaxants, muscle contraction inhibiting agents, agents inhibiting the aggregation of acetylcholine receptors, anticholinergic agents, elastase inhibiting agents, matrix metalloproteinase inhibiting agents, chelating agents, vegetable extracts, essential oils, marine extracts, mineral salts, cell extracts, emulsifying agents, agents stimulating the synthesis of lipids and components of the stratum corneum (ceramides, fatty acids, etc.), agents obtained from a bio-fermentation process and/or mixtures thereof. The nature of these cosmetic and/or dermopharmaceutical agents and/or adjuvants can be synthetic or natural, such as vegetable extracts, or come from a biotechnological process or from a combination of a synthetic process and a biotechnological process. Additional examples can be found in the CTFA International Cosmetic Ingredient Dictionary & Handbook, 12th Edition (2008). In the context of this invention, a biotechnological process is understood to be any process which produces the active ingredient, or part of it, in an organism, or in a part of it.

Liposomes bound to cationic polymers containing Liporeductyl in textile materials, their washing and resistance to washing.
The liposomes from example 3 were diluted in 50 mL water baths at 1%, 5%, 10% and 25% in weight. Different textile materials, such as polyamide (PA), cotton (CO 100%), polyester (PES), non-woven viscose (VISCOSA) and tights (TIGHTS), were submerged in each of the previous baths with ratios of textile material weight/bath of 1/25, 1/50 and 1/100 and they were kept submerged for 10 minutes at room temperature without stirring.
To test the resistance of the washing of the liposomes adhered to the previous textile materials they were treated with detergent solutions under stirring according to standard ISO 105 CO6. The quantities of active ingredient bound to the textile material after the bath and after a number of washes were determined after the extraction of caffeine from the textile material through sonication for 10 minutes in a solution of pH 3.0. Afterwards it was heated and maintained at 60° C. for 30 minutes. The external phase was filtered (0.45 μm) and was analyzed by the HPLC-UV/VIS detector. The quantities of caffeine are shown in
The textile materials were dried by being hung out according to standard UNE-EN ISO 6330 after the bath and after each wash. Typical drying times were 24 hours at room temperature.

Atomic Force Microscopy of liposomes which contain Decelerine™ bound to cationic polymers.
Images of liposomes from example 2 were taken by atomic force microscopy.
Test of transfer to skin of the active ingredients contained in liposomes of Liporeductyl® in textile materials.
The liposomes obtained in example 3 were taken and 100 μL of 2% weight aqueous solution of these liposomes was applied directly with a micropipette to a piece of cotton fabric with a surface area of 1,77 cm2.
Next the transfer test was carried out with pig skin, in accordance with a modification of the OCDE standard 428 (Skin absorption: in vitro method). The modification consisted of applying a weight to the fabric sample placed on the pig skin to simulate the pressure that the skin would exert on the fabric. The weight applied was 1 g. After 24 hours of exposure of the cotton fabric to the skin the quantity of caffeine to have reached the surface of the skin as well as the different layers of skin was determined by HPLC. It was obtained that with a pressure even as small as 0.56 g/cm2, the percentage of caffeine which passed through the surface and layer of skin was 0.40%.
