     FIELD OF THE INVENTION 
       [0002]    The present invention relates generally to cosmetic or pharmaceutical compositions and methods comprising an extract of a plant, and more particularly to cosmetic and pharmaceutical compositions and methods comprising an extract of a plant belonging to the genus  Buchholzia  and at least one auxiliary and/or additive. 
       BACKGROUND INFORMATION 
       [0003]    The genus  Buchholzia  belongs to the botanical family Capparidaceae. The plant  Buchholzia coriacea  Engler is one plant that belongs to the genus  Buchholzia . Synonyms of the name  Buchholzia coriacea  Engler are  Buchholzia coriacea, Buchholzia coriaceae  and  Buchholzia coreacea. Buchholzia tholloniana  and  Buchholzia macrophylla  are other species which belong to the genus  Buchholzia.    
         [0004]    The plant  Buchholzia coriacea  is a shrub or medium-sized tree, evergreen, with a dense crown, large glossy leathery leaves arranged spirally and clustered at the ends of the branches, and conspicuous cream-white flowers in racemes at the end of the branches. The bark of the plant  Buchholzia coriacea  is smooth, blackish-brown or dark-green. Slashes are deep red turning dark brown. 
         [0005]    The leaves of the plant  Buchholzia coriacea  can be described as follows: large, obovate, oblanceolate to elliptic, shortly acuminate or acute at apex, cuneate at base, 15-30×5-11 cm, thinly coriaceous, glabrous, midrib very prominent below, about 10 lateral nerves, each running directly into the one above and forming distinct loops close to the margin, prominent below, stalk 10-15 cm long, swollen for about 1 cm at both ends, pale green. 
         [0006]    The flowers of the plant  Buchholzia coriacea  can be described as follows: in simple or lightly-branched lax racemes among the leaves at the ends of the shoots, up to 24 cm long, individual flowers with a stalk less than 1.3 cm. 4 small rounded sepals bent right back exposing the thick saucer-shaped purplish receptacle, without petals, 40 to 45 stamens with cream-yellow filaments and small purplish-black anthers and a narrow elongated ovary projecting beyond the stamens at the end of a thin stalk. 
         [0007]    The fruits of the plant  Buchholzia coriacea  can be described as follows: large, long-stalked, ellipsoid, resembling avocado pears, 12×5-8 cm, endocarp up to 1.3 cm thick and woody, yellowish when ripe, flesh yellow, edible, containing a few large blackish seeds, about 2.5 cm long. 
         [0008]    The plant  Buchholzia coriacea  is a tree of the lowland rain forest in the region Guinea to Cameroon, and in Gabon. In Gabon the plant  Buchholzia coriacea  is sometimes cultivated as a medicinal and fetish plant. Vernacular names of the plant  Buchholzia coriacea  are Cola pimento, elephant cola, oignon de Gorille. 
         [0009]    Plants that belong to the botanical family Capparidaceae have been used in traditional ethnomedicine for several years and several genera of plants have been documented for the treatment of various ailments. 
         [0010]    Plants that belong to the botanical family Capparidaceae have been used for the treatment of syphilis, dressing of wounds, chronic ulcers and for the treatment of snake bites. Certain plants of the family Capparidaceae have been used for the treatment of gonorrhoea, convulsion in children, as aphrodisiacs and as anthelmintics. 
         [0011]    In the Ivory coast the twig bark decoction of the plant  Buchholzia coriacea  is used for the treatment of rheumatism and kidney pain, it is also used for the treatment infections of the eye (bark gruel poured into the flat of the hand and inhaled) and for the treatment of pain in the back (fruit pulp massaged in). For the treatment of earache, seeds are pounded in a little bit of water and the resulting liquid is dropped into the ear. The Ebrié tribes bathe smallpox victims with the bark decoction of the plant  Buchholzia coriacea . The sharp-tasting seed arils of the plant  Buchholzia coriacea  are chewed like cola. In Sierra Leone a paste is made from leaves of the plant  Buchholzia coriacea , fruit and white clay, which is rubbed on the body for the treatment of fever. In Nigeria, the fruit of the plant  Buchholzia coriacea  is used as an anthelmintic. In Liberia, the seeds of the plant  Buchholzia coriacea  are used internally against worms and pain, externally against skin diseases. In Cameroon, a medicine is made from the fruit of the plant  Buchholzia coriacea  for the treatment of coughs. Young leaves of the plant  Buchholzia coriacea  are used in a gruel poultice for ulcers and boils. In Gabon pounded bark of the plant  Buchholzia coriacea  is used as a lotion against scabies, the fruit of the plant  Buchholzia coriacea  as an anthelmintic. In former times young warriors were given fresh roots of the plant  Buchholzia coriacea  to stimulate them before battle. 
         [0012]    Little is known about the chemical composition of the plant  Buchholzia coriacea . The plant family Capparidaceae is well known for the presence of glucosinolates and alcaloids. 
         [0013]    According to Delaveau et al. (Delaveau P., Koudogbo B, Pousset J L.: Alcaloïdes chez les Capparidaceae, Phytochemistry, 1973, volume 12, pages 2893 to 2895), leaf samples of the plant  Buchholzia coriacea  from the Ivory Coast do not contain the alkaloid L-stachydrine and the hydroxides of tetramethylammonium, whereas these substances are found in numerous members of the family Capparidaceae. 
         [0014]    From the bark of stems of the plant  Buchholzia coriacea  Koudogbo et al. have extracted the pentacyclic triterpene lupeol and the sterols campesterol, stigmasterol and β-sitosterol as well as the aglycone of three anthocyans: pelargonidin (red-violet) cyanidin (red) and apigenidin (yellow). Three glucosinolates were found, one of them has been identified as glucocapparine, the characteristic compound of plants of the family Capparidaceae. Preliminary tests have also shown that leaves, trunk bark and roots of the plant  Buchholzia coriacea  contain tannins, proanthocyans and glycosinolates and seem to be devoided of quinones, flavonoids and alkaloids (Koudogbo B, Delaveau P., Adjanohoun. E.: Sur une Capparidacée africaine, le  Buchholzia coriacea  Engler, Annales Pharmaceutiques Françaises, 1972, volume 30, pages 93 to 98). 
         [0015]    Methanol extracts of leaves and stems of the plant  Buchholzia coriaceae  showed anthelmintic activity in vitro (Ajaiyeoba E O, Onocha P. A, Olarenwaju O T.: In vitro anthelmintic properties of  Buchholzia coriaceae  and  Gynandropsis gynandra  extracts, Pharmaceutical Biology, 2001, volume 39, pages 217 to 220). 
         [0016]    The publications “VIVIEN J, FAURE J J, Fruitiers sauvages du Cameroun, Fruits, volume 43, 1988, pages 507 to 513” and “G. E. WICKENS, Non-wood Forest products, n° 5-Edible nuts, FAO editor, 1995 page 113” disclose that the seeds or kernels of the plant  Buchholzia coriaceae  are edible and that they have a spicy taste and that they can be used as a condiment (spice). 
         [0017]    The ground seeds or kernels of the plant  Buchholzia coriaceae  are a component of a traditional and valued aphrodisiac or stimulant that is sold on local markets in Africa (Cameroon). The African plant  Buchholzia coriaceae  is used as stimulant, tonic, aphrodisiac.

         [0072]    Typical examples of suitable polyglycerol esters are polyglyceryl-2 dipolyhydroxystearate (Dehymuls® PGPH), polyglycerol-3 diisostearate (Lameform® TGI), polyglyceryl-4 isostearate (Isolan® GI 34), polyglyceryl-3 oleate, diisostearoyl polyglyceryl-3 diisostearate (Isolan® PDI), polyglyceryl-3 methylglucose distearate (Tego Care® 450), polyglyceryl-3 beeswax (Cera Bellina®), polyglyceryl-4 caprate (Polyglycerol Caprate T2010/90), polyglyceryl-3 cetyl ether (Chimexane® NL), polyglyceryl-3 distearate (Cremophor® GS 32) and polyglyceryl polyricinoleate (Admul® WOL 1403), polyglyceryl dimerate isostearate, and mixtures thereof. Examples of further suitable polyol esters are the mono-, di- and triesters, optionally reacted with 1 to 30 mol of ethylene oxide, of trimethyloipropane or pentaerythritol with lauric acid, coconut fatty acid, tallow fatty acid, palmitic acid, stearic acid, oleic acid, behenic acid and the like. 
         [0073]    Furthermore, zwitterionic surfactants can be used as emulsifiers. The term “zwitterionic surfactants” refers to those surface-active compounds that carry at least one quaternary ammonium group and at least one carboxylate and one sulfonate group in the molecule. Particularly suitable zwitterionic surfactants are the betaines, such as N-alkyl-N,N-dimethylammonium glycinates, for example cocoalkyldimethylammonium glycinate, N-acylaminopropyl-N,N-dimethylammonium glycinates, for example cocoacylaminopropyl-dimethylammonium glycinate, and 2-alkyl-3-carboxymethyl-3-hydroxyethylimidazolines having in each case 8 to 18 carbon atoms in the alkyl or acyl group, and cocoacylaminoethylhydroxyethylcarboxymethyl glycinate. Particular preference is given to the fatty acid amide derivative known under the CTFA name Cocamidopropyl Betaine. Likewise suitable emulsifiers are ampholytic surfactants. The term “ampholytic surfactants” means those surface-active compounds that, apart from a C 8/18 -alkyl or -acyl group in the molecule, contain at least one free amino group and at least one —COOH or —SO 3 H group and are capable of forming internal salts. Examples of suitable ampholytic surfactants are N-alkylglycines, N-alkylpropionic acids, N-alkylaminobutyric acids, N-alkyliminodipropionic acids, N-hydroxyethyl-N-alkylamidopropylglycines, N-alkyltaurines, N-alkylsarcosines, 2-alkylamino-propionic acids and alkylaminoacetic acids having in each case about 8 to 18 carbon atoms in the alkyl group. Particularly preferred ampholytic surfactants are N-cocoalkyl aminopropionate, cocoacylaminoethyl aminopropionate and C 12/18 -acylsarcosine. Finally, cationic surfactants are also suitable emulsifiers, those of the ester quat type, preferably methyl-quaternized difatty acid triethanolamine ester salts, being particularly preferred. 
         [0074]    Fats and waxes that can be used are described in the following text. Typical examples of fats are glycerides, i.e. solid or liquid vegetable or animal products which consist essentially of mixed glycerol esters of higher fatty acids, suitable waxes are inter alia natural waxes, for example candelilla wax, carnauba wax, japan wax, esparto grass wax, cork wax, guaruma wax, rice germ oil wax, sugarcane wax, ouricury wax, montan wax, beeswax, shellac wax, spermaceti, lanolin (wool wax), uropygial grease, ceresin, ozokerite (earth wax), petrolatum, paraffin waxes, microcrystalline waxes; chemically modified waxes (hard waxes), for example montan ester waxes, sasol waxes, hydrogenated jojoba waxes, and synthetic waxes, for example polyalkylene waxes and polyethylene glycol waxes. In addition to the fats, suitable additives are also fat-like substances, such as lecithins and phospholipids. The term lecithins is understood by the person skilled in the art as meaning those glycerophospholipids which form from fatty acids, glycerol, phosphoric acid and choline by esterification. Lecithins are thus frequently also known as phosphatidylcholines (PC). Examples of natural lecithins which may be mentioned are the cephalins, which are also referred to as phosphatidic acids and represent derivatives of 1,2-diacyl-sn-glycerol-3-phosphoric acids. By contrast, phospholipids are usually understood as meaning mono- and, preferably, diesters of phosphoric acid with glycerol (glycerophosphates), which are generally considered to be fats. In addition, sphingosines and sphingolipids are also suitable. 
         [0075]    Examples of suitable pearlescent waxes are: alkylene glycol esters, specifically ethylene glycol distearate; fatty acid alkanolamides, specifically coconut fatty acid diethanolamide; partial glycerides, specifically stearic acid monoglyceride; esters of polybasic, optionally hydroxy-substituted carboxylic acids with fatty alcohols having 6 to 22 carbon atoms, specifically long-chain esters of tartaric acid; fatty substances, for example fatty alcohols, fatty ketones, fatty aldehydes, fatty ethers and fatty carbonates, which have a total of at least 24 carbon atoms, specifically laurone and distearyl ether; fatty acids, such as stearic acid, hydroxystearic acid or behenic acid, ring-opening products of olefin epoxides having 12 to 22 carbon atoms with fatty alcohols having 12 to 22 carbon atoms and/or polyols having 2 to 15 carbon atoms and 2 to 10 hydroxyl groups, and mixtures thereof. 
         [0076]    Bodying agents and thickeners that can be used are described in the following text. Suitable bodying agents are primarily fatty alcohols or hydroxy fatty alcohols having 12 to 22, and preferably 16 to 18, carbon atoms, and also partial glycerides, fatty acids or hydroxy fatty acids. Preference is given to a combination of these substances with alkyl oligoglucosides and/or fatty acid N-methylglucamides of identical chain length and/or polyglycerol poly-12-hydroxystearates. Suitable thickeners are, for example, Aerosil grades (hydrophilic silicas), polysaccharides, in particular xanthan gum, guar guar, agar agar, alginates and Tyloses, carboxymethylcellulose and hydroxyethylcellulose, and also relatively high molecular weight polyethylene glycol mono- and diesters of fatty acids, polyacrylates (e.g. Carbopols® and Pemulen grades from Goodrich; Synthalens® from Sigma; Keltrol grades from Kelco; Sepigel grades from Seppic; Salcare grades from Allied Colloids), polyacrylamides, polymers, polyvinyl alcohol and polyvinylpyrrolidone, surfactants, for example ethoxylated fatty acid glycerides, esters of fatty acids with polyols for example pentaerythritol or trimethylolpropane, fatty alcohol ethoxylates having a narrowed homolog distribution or alkyl oligoglucosides, and electrolytes such as sodium chloride and ammonium chloride. 
         [0077]    Superfatting agents which can be used are for example lanolin and lecithin, and polyethoxylated or acylated lanolin and lecithin derivatives, polyol fatty acid esters, monoglycerides and fatty acid alkanolamides, the latter also serving as foam stabilizers. 
         [0078]    Stabilizers which can be used are metal salts of fatty acids, for example magnesium, aluminium and/or zinc stearate or ricinoleate. 
         [0079]    Polymers that can be used are described in the following text. Suitable cationic polymers are, for example, cationic cellulose derivatives, for example a quaternized hydroxyethylcellulose obtainable under the name Polymer JR 400® from Amerchol, cationic starch, copolymers of diallylammonium salts and acryl amides, quaternized vinylpyrrolidone-vinylimidazole polymers, for example Luviquat® (BASF), condensation products of polyglycols and amines, quaternized collagen polypeptides, for example lauryldimonium hydroxypropyl hydrolysed collagen (Lamequat®/Grünau), quaternized wheat polypeptides, polyethyleneimine, cationic silicone polymers, for example amodimethicones, copolymers of adipic acid and dimethylaminohydroxypropyl-diethylenetriamine (Cartaretins®/Sandoz), copolymers of acrylic acid with dimethyl diallylammonium chloride (Merquat® 550/Chemviron), polyaminopolyamides and cross linked water-soluble polymers thereof, cationic chitin derivatives, for example quaternized chitosan, optionally in microcrystalline dispersion, condensation products from dihaloalkyls, for example dibromobutane with bisdialkylamines, for example bis-dimethylamino-1,3-propane, cationic guar gum, for example Jaguar® CBS, Jaguar® C-17, Jaguar® C-16 from Celanese, quaternized ammonium salt polymers, for example Mirapol® A-15, Mirapol® AD-1, Mirapol® AZ-1 from Miranol. 
         [0080]    Suitable anionic, zwitterionic, amphoteric and nonionic polymers are, for example, vinyl acetate-crotonic acid copolymers, vinylpyrrolidone-vinyl acrylate copolymers, vinyl acetate-butyl maleate-isobornyl acrylate copolymers, methyl vinyl ether-maleic anhydride copolymers and esters thereof, uncrosslinked polyacrylic acids and polyacrylic acids crosslinked with polyols, acrylamidopropyltrimethylammonium chloride-acrylate copolymers, octylacrylamide-methyl methacrylate-tert-butylaminoethyl methacrylate-2-hydroxypropyl methacrylate copolymers, polyvinylpyrrolidone, vinylpyrrolidone-vinyl acetate copolymers, vinyl pyrrolidone-dimethylaminoethyl methacrylate-vinylcaprolactam terpolymers, and optionally derivatized cellulose ethers and silicones. 
         [0081]    Suitable silicone compounds are, for example, dimethylpolysiloxanes, methylphenylpolysiloxanes, cyclic silicones, and amino-, fatty-acid-, alcohol-, polyether-, epoxy-, fluorine-, glycoside- and/or alkyl-modified silicone compounds, which can either be liquid or in resin form at room temperature. Also suitable are simethicones, which are mixtures of dimethicones having an average chain length of from 200 to 300 dimethylsiloxane units and hydrogenated silicates. 
         [0082]    Deodorants and antimicrobial agents that can be used are described in the following text. Cosmetic deodorants counteract, mask or remove body odors. Body odors arise as a result of the effect of skin bacteria on apocrine perspiration, with the formation of degradation products which have an unpleasant odor. Accordingly, deodorants comprise active ingredients which act as antimicrobial agents, enzyme inhibitors, odor absorbers or odor masking agents. Suitable antimicrobial agents are, in principle, all substances effective against gram-positive bacteria, for example 4-hydroxybenzoic acid and its salts and esters, N-(4-chlorophenyl)-N′-(3,4-dichlorophenyl)urea, 2,4,4′-trichloro-2′-hydroxydiphenyl ether (triclosan), 4-chloro-3,5-dimethylphenol, 2,2′-methylenebis(6-bromo-4-chlorophenol), 3-methyl-4-(1-methylethyl)phenol, 2-benzyl-4-chlorophenol, 3-(4-chlorophenoxy)-1,2-propanediol, 3-iodo-2-propynyl butylcarbamate, chlorohexidine, 3,4,4′-trichlorocarbanilide (TTC), antibacterial fragrances, thymol, thyme oil, eugenol, oil of cloves, menthol, mint oil, farnesol, phenoxyethanol, glycerol monocaprate, glycerol monocaprylate, glycerol monolaurate (GML), diglycerol monocaprate (DMC), salicylic acid N-alkylamides, for example n-octylsalicylamide or n-decylsalicylamide. 
         [0083]    Suitable enzyme inhibitors are, for example, esterase inhibitors. These are preferably trialkyl citrates, such as trimethyl citrate, tripropyl citrate, triisopropyl citrate, tributyl citrate and, in particular, triethyl citrate (Hydagen® CAT). The substances inhibit enzyme activity, thereby reducing the formation of odor. Other substances which are suitable esterase inhibitors are sterol sulfates or phosphates, for example lanosterol, cholesterol, campesterol, stigmasterol and sitosterol sulfate or phosphate, dicarboxylic acids and esters thereof, for example glutaric acid, monoethyl glutarate, diethyl glutarate, adipic acid, monoethyl adipate, diethyl adipate, malonic acid and diethyl malonate, hydroxycarboxylic acids and esters thereof, for example citric acid, malic acid, tartaric acid or diethyl tartrate, and zinc glycinate. 
         [0084]    Suitable odor absorbers are substances which are able to absorb and largely retain odor-forming compounds. They lower the partial pressure of the individual components, thus also reducing their rate of diffusion. It is important that in this process perfumes must remain unimpaired. Odor absorbers are not effective against bacteria. They comprise, for example, as main constituent, a complex zinc salt of ricinoleic acid or specific, largely odor-neutral fragrances which are known to the person skilled in the art as “fixatives”, for example extracts of labdanum or styrax or certain abietic acid derivatives. The odor masking agents are fragrances or perfume oils, which, in addition to their function as odor masking agents, give the deodorants their respective fragrance note. Perfume oils which may be mentioned are, for example, mixtures of natural and synthetic fragrances. Natural fragrances are extracts from flowers, stems and leaves, fruits, fruit peels, roots, woods, herbs and grasses, needles and branches, and resins and balsams. Also suitable are animal raw materials, for example civet and castoreum. Typical synthetic fragrance compounds are products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type. Fragrance compounds of the ester type are, for example, benzyl acetate, p-tert-butylcyclohexyl acetate, linalyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, allyl cyclohexylpropionate, styrallyl propionate and benzyl salicylate. The ethers include, for example, benzyl ethyl ether, and the aldehydes include, for example, the linear alkanals having 8 to 18 carbon atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamen aldehyde, hydroxycitronellal, lilial and bourgeonal, the ketones include, for example, the ionones and methyl cedryl ketone, the alcohols include anethole, citronellol, eugenol, isoeugenol, geraniol, linalool, phenylethyl alcohol and terpineol, and the hydrocarbons include mainly the terpenes and balsams. Preference is, however, given to using mixtures of different fragrances which together produce a pleasing fragrance note. Ethereal oils of relatively low volatility, which are mostly used as aroma components, are also suitable as perfume oils, e.g. sage oil, camomile oil, oil of cloves, melissa oil, mint oil, cinnamon leaf oil, linden flower oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil, labdanum oil and lavandin oil. Preference is given to using bergamot oil, dihydromyrcenol, lilial, lyral, citronellol, phenylethyl alcohol, α-hexylcinnamaldehyde, geraniol, benzylacetone, cyclamen aldehyde, linalool, boisambrene forte, ambroxan, indole, hedione, sandelice, lemon oil, mandarin oil, orange oil, allyl amyl glycolate, cyclovertal, lavandin oil, clary sage oil, β-damascone, geranium oil bourbon, cyclohexyl salicylate, Vertofix coeur, iso-E-super, Fixolide NP, evernyl, iraldein gamma, phenylacetic acid, geranyl acetate, benzyl acetate, rose oxide, romilat, irotyl and floramat alone or in mixtures. 
         [0085]    Antiperspirants reduce the formation of perspiration by influencing the activity of the eccrine sweat glands, thus counteracting underarm wetness and body odor. Aqueous or anhydrous formulations of antiperspirants typically comprise one or more of the following ingredients: astringent active ingredients, oil components, nonionic emulsifiers, coemulsifiers, bodying agents, auxiliaries, for example thickeners or complexing agents, and/or nonaqueous solvents, for example ethanol, propylene glycol and/or glycerol. 
         [0086]    Suitable astringent antiperspirant active ingredients are primarily salts of aluminum, zirconium or of zinc. Such suitable antihydrotic active ingredients are, for example, aluminum chloride, aluminum chlorohydrate, aluminum dichlorohydrate, aluminum sesquichlorohydrate and complex compounds thereof, e.g. with 1,2-propylene glycol, aluminum hydroxyallantoinate, aluminum chloride tartrate, aluminum zirconium trichlorohydrate, aluminum zirconium tetrachlorohydrate, aluminum zirconium pentachlorohydrate and complex compounds thereof, e.g. with amino acids, such as glycine. In addition, customary oil-soluble and water-soluble auxiliaries may be present in antiperspirants in relatively small amounts. Such oil-soluble auxiliaries may, for example, be anti-inflammatory, skin-protective or perfumed ethereal oils, synthetic skin-protective active ingredients and/or oil-soluble perfume oils. 
         [0087]    Customary water-soluble additives are, for example, preservatives, water-soluble fragrances, pH regulators, e.g. buffer mixtures, water-soluble thickeners, e.g. water-soluble natural or synthetic polymers, for example xanthan gum, hydroxyethylcellulose, polyvinylpyrrolidone or high molecular weight polyethylene oxides. 
         [0088]    Film formers that can be used are described in the following text. Customary film formers are, for example, chitosan, microcrystalline chitosan, quaternized chitosan, polyvinylpyrrolidone, vinylpyrrolidone-vinyl acetate copolymers, polymers of the acrylic acid series, quaternary cellulose derivatives, collagen, hyaluronic acid and salts thereof, and similar compounds. 
         [0089]    Suitable antidandruff active ingredients are piroctone olamine (1-hydroxy-4-methyl-6-(2,4,4-trimethylpentyl)- 2 -(1H)-pyridinone monoethanolamine salt), Baypival® (climbazole), Ketoconazole®, (4-acetyl-1-{-4-[2-(2,4-dichlorophenyl) r-2-(1H-imidazol-1-ylmethyl)-1,3-dioxylan-c-4-ylmethoxyphenyl}piperazine, ketoconazole, elubiol, selenium disulfide, colloidal sulfur, sulfur polyethylene glycol sorbitan monooleate, sulfur ricinol polyethoxylate, sulfur tar distillates, salicyclic acid (or in combination with hexachlorophene), undecylenic acid monoethanolamide sulfosuccinate Na salt, Lamepon® UD (protein undecylenic acid condensate), zinc pyrithione, aluminum pyrithione and magnesium pyrithione/dipyrithione magnesium sulfate. 
         [0090]    The swelling agents for aqueous phases may be montmorillonites, clay mineral substances, Pemulen, and alkyl-modified Carbopol grades (Goodrich). 
         [0091]    Suitable insect repellents are N,N-diethyl-m-toluamide, 1,2-pentanediol or ethyl butylacetylaminopropionate. 
         [0092]    To improve the flow behavior, hydrotropes, for example ethanol, isopropyl alcohol, or polyols, can be used. Polyols which are suitable here preferably have 2 to 15 carbon atoms and at least two hydroxyl groups. The polyols can also contain further functional groups, in particular amino groups, or be modified with nitrogen. Typical examples are:
       glycerol;   alkylene glycols, for example, ethylene glycol, diethylene glycol, propylene glycol, butylene glycol, hexylene glycol, and polyethylene glycols with an average molecular weight of from 100 to 1 000 daltons;   technical-grade oligoglycerol mixtures with a degree of self-condensation of from 1.5 to 10, for example, technical-grade diglycerol mixtures with a diglycerol content of from 40 to 50% by weight;   methylol compounds, such as trimethylolethane, trimethylolpropane, trimethylolbutane, pentaerythritol and dipentaerythritol;   lower alkyl glucosides, in particular those with 1 to 8 carbon atoms in the alkyl radical, for example methyl and butyl glucoside;   sugar alcohols with 5 to 12 carbon atoms, for example sorbitol or mannitol,   sugars with 5 to 12 carbon atoms, for example glucose or sucrose;   amino sugars, for example glucamine;   dialcohol amines, such as diethanolamine or 2-amino-1,3-propanediol.       
 
         [0102]    Suitable preservatives are, for example, phenoxyethanol, formaldehyde solution, parabenes, pentanediol or sorbic acid, and the other classes of substance listed in Annex 6, Part A and B of the Cosmetics Directive. 
         [0103]    Perfume oils which may be used are preferably mixtures of natural and synthetic fragrances. Natural fragrances are extracts from flowers (lily, lavender, rose, jasmine, neroli, ylang-ylang), stems and leaves (geranium, patchouli, petitgrain), fruits (aniseed, coriander, cumin, juniper), fruit peels (bergamot, lemon, orange), roots (mace, angelica, celery, cardamom, costus, iris, calmus), woods (pine wood, sandalwood, guaiac wood, cedarwood, rosewood), herbs and grasses (tarragon, lemon grass, sage, thyme), needles and branches (spruce, fir, pine, dwarf-pine), resins and balsams (galbanum, elemi, benzoin, myrrh, olibanum, opoponax). Also suitable are animal raw materials, for example civet and castoreum. Typical synthetic fragrance compounds are products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type. Fragrance compounds of the ester type are, for example, benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, ethylmethylphenyl glycinate, allyl cyclohexylpropionate, styrallyl propionate and benzyl salicylate. The ethers include, for example, benzyl ethyl ether, the aldehydes include, for example, the linear alkanals having 8 to 18 carbon atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamen aldehyde, hydroxycitronellal, lilial and bourgeonal, and the ketones include, for example, the ionones, α-isomethylionone and methyl cedryl ketone, the alcohols include anethole, citronellol, eugenol, isoeugenol, geraniol, linalool, phenylethyl alcohol and terpineol, and the hydrocarbons include predominantly the terpenes and balsams. Preference is, however, given to using mixtures of different fragrances which together produce a pleasing fragrance note. Ethereal oils of relatively low volatility, which are mostly used as aroma components, are also suitable as perfume oils, e.g. sage oil, camomile oil, oil of cloves, melissa oil, mint oil, cinnamon leaf oil, linden blossom oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil, labolanum oil and lavandin oil.

         [0104]    Dyes which can be used are the substances which are approved and suitable for cosmetic purposes. These dyes are normally used in concentrations of from 0.001 to 0.1% by weight, based on the total mixture. 
       EXAMPLES 
       [0105]    % (w/v) means “% weight by volume”, 1% (w/v) means 1 g per 100 ml. 
       Example 1 
     Hot Water Extract 
       [0106]    200 g of dry seeds of the plant  Buchholzia coriacea  were crushed in a blade crusher. Then they were introduced in a glass reactor containing 2 liters of distilled water (ratio raw material to solvent=1 to 10). Extraction was carried out under shaking for one hour at a temperature of 80 to 85° C. Then the mixture was cooled to room temperature (20° C.). The liquid and the solid fraction were separated by centrifugation at 5000 g for 15 min and subsequent filtration through depth filters (0.45 μm). The yellow extract was dried by spray-drying. The yield based on extracted seeds was 13.6%. 
       Example 2 
     Water Extract at Room Temperature 
       [0107]    200 g of dry seeds of the plant  Buchholzia coriacea  were crushed in a blade crusher. Then they were introduced in a glass reactor containing 2 liters of distilled water (ratio raw material to solvent=1 to 10). Optionally, the suspension could be treated with ultrasonic to accelerate the extraction (conditions: time: 10 minutes, pulse: 5 seconds, time of latency between 2 pulsations: 9.9 seconds, amplitude: 100%). The suspension was extracted under shaking for one hour at room temperature (25° C.). The liquid and the solid fraction were separated by centrifugation at 5000 g for 15 minutes and subsequent filtration through depth filters (0.45 μm). The filtrate was yellow. The yellow extract was dried by freeze-drying or by spray-drying. The yield based on extracted seeds was 8.9 to 14.5% depending on the batch of raw material used. 
       Example 3 
     Maltodextrine Addition 
       [0108]    Maltodextrine (50% by weight) was added to the solution of example 3 before spray-drying. 
       Example 4 
     Extraction with a Mixture of Ethanol and Water (70% by Volume Ethanol) 
       [0109]    In a glass reactor 2 liters of ethanol in water (70%) and 200 g of crushed seeds of the plant  Buchholzia coriacea  were combined. Extraction was carried out under shaking for 1 hour under reflux. Then the mixture was cooled to room temperature. The liquid and the solid fraction were separated by filtration through depth filters (5 μm). the insoluble residue was rinsed with 200 ml of ethanol (70% in water). The two filtrates were added and filtered through a 0.45 μm-filter. Concentration of the resulting liquid was carried out under vacuum at 30° C. Then it was freeze-dried. The yield of extract was 7.4 to 8.1% relative to the crushed seeds depending on the batch of raw material used. 
       Example 5 
     Revitalizing and Regenerating Effect of the Extracts According to Examples 1 to 3 
     Aim and Principle of Example 5 
       [0110]    The purpose of these tests is to evaluate the revitalizing and regenerating activities of plant extracts on human fibroblasts cultured in vitro. 
       Method of Example 5: 
       [0111]    The growth efficacy test was carried out on human fibroblasts to evaluate the regenerating and the growth factor like activities. The survival efficacy test was carried out on human fibroblasts to evaluate the regenerating and the revitalizing activities. 
         [0112]    The cell number and the cell viability have been determined by recording the following parameters:
       Protein levels were evaluated according to Bradford&#39;s method (Bradford: A rapid and sensitive method for the quantification of microgram quantities of protein utilizing the principle of protein-dye binding, Analytical Biochemistry, volume 72, pages 248 to 254, 1976)   Glutathione (GSH) is a peptide produced by the cells to protect them against oxidative stress or against certain pollutants like mercury or lead. The three amino acids involved into the reduced form of GSH are linked by specific cytoplasmic enzymes which use ATP (adenosine triphosphate). The GSH level was evaluated by the method of Hissin (Hissin P. J., Hilf R.: A fluorometric method for determination of oxidized and reduced glutathione in tissues, Analytical Biochemistry, 1976, volume 74, pages 214 to 226)   The DNA levels were evaluated with a fluorescent probe (Hoechst  33258 ) (Desaulniers D., Leingartner K., Zacharewski T. and W. G. Foster W. G.: Optimisation of an MCF7-E3 cell proliferation assay and effects of environmental pollutants and industrial chemicals, 1998, Toxic In vitro, volume 12 number 4, pages 409 to 422)   ATP (adenosine triphosphate) is a compound rich in energy and mainly produced from mitochondria. The cells need ATP for the activity of many enzymes which control the cytoskeleton, the ionic channels, the nutriment intake, and a lot of other biological processes (Vasseur P., Aerts C.: Appreciation de la cytotoxicité par la mesure de l&#39;ATP, Journal Français Hydrologie, 1978, volume 9, pages 149 to 156).       
 
         [0117]    The results were calculated referring to a standard range and in percent versus the control and finally expressed as the average of typically 2 or 3 assays, carried out in triplicate.

Conclusions from Example 5:
       The extracts have not shown any toxic effect on cultured human fibroblasts 0.25-0.3% (w/v).   The extracts at 0.1% (w/v) have distinctly improved the growth and the metabolism of human fibroblasts cultured in vitro.   Therefore the extracts have presented a good potential as anti-aging, rejuvenant and revitalizing active ingredient for cosmetic applications.

       Example 7 
     Inhibition of UVB Effect on Human Keratinocytes 
       [0133]    Aim of the experiment: Determination of the potential of the tested ingredient to reduce negative effects of UV-B radiation on the survival rate of human keratinocytes. 
         [0134]    It is well known that UV-B radiation induces a cutaneous inflammation by stimulation of enzymes such as phospholipase A2 (PLA2). This enzyme catalyses the release of arachidonic acid which is a precursor of mediators of inflammation like the prostaglandin PGE2. Moreover this membrane stress results in the release of a cytoplasmic enzyme: lactate dehydrogenase (LDH).
