Description

IN THE MATTER OF Australian patent application based on International patent application (PCT/EP2006/002890) In the name of Henkel Kommanditgesellschaft auf Aktien DECLARATION 1, Pierre KIHN, 234, route d'Arlon, L-8001 Strassen (Luxembourg), hereby declare that I am conversant with the German and English languages and am a competent translator thereof. I declare further that to the best of my knowledge and belief the following is a true and correct translation of the above-identified PCT. Declared at Strassen, this 23.08.2007 Pierre IHN PCT/EP2006/002890 H 06592 BODY CLEANING COMPOSITION IN A NOVEL APPLICATION FORM FOR COSMETICS [0002] The invention relates to bath foam concentrates containing a water content of max. 7 wt. %, comprised in a water-soluble liquid film. [00031 Bath foams are added to the bath water to develop a voluminous foam of fine bubbles, to lend a pleasant fragrance to the bath water and to clean the body. However, for the case of longer bath times, the water and the degreasing action of the surfactants in the foam baths can degrease the skin and therefore damage it. Consequently, it was proposed in the past to alleviate this problem by adding cosmetic oil components, moisturizers and skin humectants and/or water-soluble proteins or protein degradation products, and at the same time achieve an improvement in the skin condition. [0004] DE-OS-29 43 202 describes a care bubble bath composition containing 20 to 80 wt.% of surface-active agents and 20 to 80 wt.% cosmetic oils. Bath additives are also described in DE-OS 27 00 891. They comprise 40 to 75 wt.% surface-active substances and 15 to 50 wt.% cosmetic oils. The elevated surfactant content in the formulations ensures that the cosmetic oils essentially dissolve or make them dispersible in the water. However, the products are not satisfactory in regard to the foaming behavior and they leave behind unwanted, distinctly oily residues on the skin. Other highly concentrated surfactant compositions have the disadvantage that they form stiff pastes or that when attempting to dissolve them in water they form difficultly soluble, solid gel particles which again require the addition of solvents or solubilizers to remove them.

H06592 [0005] Consequently, a bath foam concentrate was proposed in EP 288 919 Al, which develops a rich foam, dissolves high amounts of perfume oils, neither harms the skin nor leaves behind an oily film on the skin, and dissolves quickly and easily in water. The bath foam contains 35 to 45 wt.% anionic surfactants, 5 to 15 wt.% non-ionic surfactants, 1 to 5 wt.% zwitterionic surfactants and about 3 to 15 wt. % cosmetic oil components. [0006] In spite of this, the total surfactant content of the bath foam concentrate is at least 41 wt.%, as otherwise the high oil contents could not be satisfactorily dissolved. [0007] A further problem is that because of the elevated oil content in the bath foam, the volume of foam is nevertheless felt by the consumer to be unsatisfactory, and often too much bath foam is added to the bath water in order to produce a larger volume of foam. The result is that the abovementioned problems again appear on the skin. [0008] Accordingly, the object of the present invention was to provide a bath foam concentrate that does not exhibit the abovementioned disadvantages. [0009] This object was achieved to a high degree by the inventive bath foam concentrate containing a low water content, which is comprised in a water-soluble liquid film. [0010] The subject of the invention is therefore a bath foam concentrate that contains a total water content of max. 7 wt.% and comprises surfactants, polyols and at least one fatty component and is comprised in a water soluble liquid film. [0011] The inventive bath foam concentrates are characterized by a good foam formation and skin compatibility. By packaging the concentrate in a 2 H06592 water-soluble envelope, one ensures that only the amount of the concentrate required for a full bath is released by a rapid, simple and residue-free dissolution of the envelope. This is advantageous both for the condition of the skin as well as from the point of view of costs. Due to the low water content of max. 7 wt.%, the water-soluble packaging is not destroyed. [0012] Inventively suitable liquid films consist of polyvinyl alcohol and have a thickness of 70 to 80 pm and a size of 130 to 150 x 80 to 90 mm. Particularly suitable liquid films are those marketed by the Monosol Company (Chris Craft) under the trade name M 8630. For a suitable single dose portion of the inventive bath foam concentrate, they have a thickness of 76 pm and size of about 145 x 85 mm. [0013] In a preferred embodiment of the invention, the bath foam concentrates comprise a mixture of anionic and non-ionic surfactants. [0014] Inventively particularly suitable anionic surfactants are the alkyl ether sulfate surfactants corresponding to the formula

Sodium or ammonium lauryl ether sulfates with an ethoxylation degree of 2 to 4 are particularly suitable according to the invention. They are added in the inventive bath foam concentrates - based on their total weight - preferably in an amount of 12 to 25 wt.% and particularly in an amount of 15 to 20 wt.%. [0015] Inventively suitable non-ionic surfactants are the compounds of the formula 3 H06592

(0016] Laureth-2 and/or Laureth-4 are particularly suitable. They are added in the inventive bath foam concentrates - based on their total weight preferably in an amount of 8 to 15 wt.% and particularly in an amount of 10 to 14 wt.%. [0017] In addition, alkyl polyglucosides can be added as the inventively suitable non-ionic surfactants. [0018] Inventive alkyl polyglucosides corresponding to the general formula RO-(Z)x - wherein R stands for alkyl, Z for sugar and x for the number of the sugar units. The alkyl polyglycosides used according to the invention may simply comprise a defined alkyl group R. However normally, these compounds are manufactured from natural fats and oils or mineral oils. In which case, the alkyl groups R are present as mixtures corresponding to the starting compounds or to each of the compounds worked up. [0019] Alkyl polyglycosides are particularly preferred, in which R consists - essentially of C8 and C 1 0 alkyl groups, - essentially of C12 and C14 alkyl groups - essentially of C8 to C16 alkyl groups or - essentially of C12 to C16 alkyl groups or - essentially of C16 to C18 alkyl groups. [0020] Any mono or oligosaccharide can be added as the sugar building block Z. Usually, sugars with 5 or 6 carbon atoms as well as the corresponding 4 H06592 oligosaccharides are used. Such sugars are for example, glucose, fructose, galactose, arabinose, ribose, xylose, lyxose, allose, altrose, mannose, gulose, dose, talose and sucrose. Preferred sugar building blocks are glucose, fructose, galactose, arabinose and sucrose; glucose is particularly preferred. [0021] The alkyl polyglycosides used according to the invention comprise on average 1.1 to 5 sugar units. Alkyl polyglycosides with x-values of 1.1 to 2.0 are preferred. Alkyl polyglycosides with x-values of 1.1 to 1.8 are quite particularly preferred. [0022] The alkoxylated homologs of the cited alkyl polyglycosides can also be used according to the invention. These homologs can comprise on average up to 10 ethylene oxide and/or propylene oxide units per alkyl glycoside unit. [0023] Particularly preferred alkyl polyglucosides are the commercial products Plantacare* 1200 UP, Plantacare* 818 UP and Plantacare* 2000 UP from Cognis. They are added in the inventive bath foam concentrates based on their total weight - preferably in an amount of 8 to 15 wt.% and particularly in an amount of 10 to 14 wt.%. [0024] Inventively suitable polyols preferably comprise 2 to 15 carbon atoms and at least two hydroxyl groups. Typical examples are - Glycerol; - Alkylene glycols, such as, for example, ethylene glycol, diethylene glycol, propylene glycol, butylene glycol, hexylene glycol as well as polyethylene glycols with an average molecular weight of 100 to 1000 daltons, especially with a molecular weight of 400 to 600 daltons; 5 H06592 - Industrial oligoglycerol mixtures with a degree of self-condensation of 1.5 to 10 such as for instance industrial diglycerol mixtures with a diglycerol content of 40 to 50 wt.%; - Methylol compounds such as in particular trimethylol ethane, trimethylol propane, trimethylol butane, pentaerythritol and dipentaerythritol; - Lower alkyl glucosides, particularly those with 1 to 8 carbon atoms in the alkyl group, such as, for example methyl and butyl glucoside; - Sugar alcohols with 5 to 12 carbon atoms, such as, for example sorbitol or mannitol, - Sugars with 5 to 12 carbon atoms, such as, for example glucose or saccharose; - Amino sugars, such as for example glucamine. [0025] The bath foam concentrates particularly preferably comprise mixtures of a plurality of polyols. A mixture of at least two representatives of the group glycerol, sorbitol, 1,2-propylene glycol and/or polyethylene glycol is particularly preferred. [0026] The polyol mixture is particularly preferably incorporated in the bath foam concentrates in amounts of 30 to 65 wt.% and particularly in amounts of 40 to 60 wt.%. [0027] According to the invention, glycerol polyglycol ether mono fatty acid esters are suitable hydrophilic oil components with a skin moisturizing effect. Products of this structure are known from the literature, for example from DE-A-20 24 051, and in commerce, for example under the trade name Cetiol@ HE (Cognis). Inventively suitable fatty acid mono or diglyceride polyglycol ethers are also known in the literature as moisturizing components, for example from US 2,617,754 and from DE A-14 67 816. Cetiol@ HE is particularly suitable. This commercial product 6 H06592 is preferably incorporated in the bath foam concentrates, based on the total weight, in amounts of 2 to 6 wt.%. [0028] In a particularly preferred embodiment of the invention, the bath foam concentrates further comprise a cationic polymer. [0029] Cationic polymers are understood to mean polymers that, in their main chain and/or side chain, possess groups that can be "temporarily" or "permanently" cationic. "Permanently cationic" refers, according to the invention, to those polymers, which independently of the pH of the medium exhibit a cationic group. These are generally polymers, which comprise a quaternary nitrogen atom, in the form of an ammonium group, for example. Preferred cationic groups are quaternary ammonium groups. In particular, those polymers in which the quaternary ammonium groups are bonded through a C 14 hydrocarbon group to a polymer backbone of acrylic acid, methacrylic acid or their derivatives, have proved to be particularly suitable. [0030] Homopolymers of the general formula (VI), R17 -[CH2-C-]n X (Vi) CO-0-(CH,1m-N R18R19R20 - in which R 17 = -H or -CH 3 , R 1 8 , R" and R 20 independently of each other are selected from C 1 4 alkyl, -alkenyl or -hydroxyalkyl groups, m = 1, 2, 3 or 4, n = a natural number and X is a physiologically compatible organic or inorganic anion, as well as copolymers, essentially consisting of the monomer units listed in formula (VI) as well as non-ionic monomer units, are particularly preferred cationic polymers. Regarding these polymers, those that are preferred in accordance with the invention meet at least one of the following conditions: 7 H06592 - R 17 stands for a methyl group - R 18 , R" and R 20 stand for methyl groups - m has the value 2. [0031] Exemplary physiologically compatible counter ions X- include halide ions, sulfate ions, phosphate ions, methosulfate ions as well as organic ions such as lactate, citrate, tartrate and acetate ions. Halide ions are preferred, particularly chloride. [0032] A suitable homopolymer is the optionally crosslinked poly(methacryloyloxyethyl trimethyl ammonium chloride) with the INCI name Polyquaternium-37. Crosslinking can be effected, when desired, with the help of olefinically polyunsaturated compounds, for example divinylbenzene, tetraallyloxyethane, methylene bisacrylamide, diallyl ether, polyallyl polyglyceryl ether, or allyl ethers of sugars or sugar derivatives such as erythritol, pentaerythritol, arabitol, mannitol, sorbitol, sucrose or glucose. Methylene bisacrylamide is a preferred crosslinking agent. [0033] The homopolymer is preferably employed in the form of a non-aqueous polymer dispersion that should have a polymer content of not less than 30 wt.%. Such polymer dispersions are commercially available under the names Salcare@ SC 95 (ca. 50 % polymer content, additional components: mineral oil (INCI name: Mineral Oil) and tridecyl polyoxypropylene polyoxyethylene ether (INCI name: PPG-1-Trideceth 6)) and Salcare@ SC 96 (ca. 50 % polymer content, additional components: mixture of diesters of propylene glycol with a mixture of caprylic- and capric acid (INCI name: Propylene Glycol Dicaprylate/Dicaprate) and tridecyl-polyoxypropylene polyoxyethylene ether (INCI name: PPG-1 -Trideceth-6)). 8 H06592 [0034] Copolymers with monomer units according to formula (VI) preferably comprise acrylamide, methacrylamide, C1 alkyl esters of acrylic acid and CiA alkyl esters of methacrylic acid as the non-ionic monomer units. Acrylamide is particularly preferred among these non-ionic monomers. These copolymers can also be crosslinked, as in the case of the above described homopolymers. An inventively preferred copolymer is the crosslinked acrylamide/methacryloyloxyethyl trimethyl ammonium chloride copolymer. Such copolymers, in which the monomers are present in a weight ratio of about 20: 80, are commercially available as a ca. 50 % conc. non-aqueous polymer dispersion named Salcare* SC 92. [0035] Further preferred cationic polymers are for example - quaternized cellulose derivatives, commercially available under the names Celquat* and Polymer JR*. The compounds Celquat* H 100, Celquat* L 200 and Polymer JR*400 are preferred quaternized cellulose derivatives, - cationic alkyl polyglycosides according to DE-PS 44 13 686, - cationized honey, for example the commercial product Honeyquat* 50, - cationic guar derivatives, such as in particular the products marketed under the trade names Cosmedia* Guar and Jaguar*, - polysiloxanes with quaternary groups, such as, for example, the commercially available products Q2-7224 (manufacturer: Dow Corning; a stabilized trimethylsilylamodimethicone), Dow Corning 929 emulsion (comprising a hydroxylamino-modified silicone, also referred to as amodimethicone), SM-2059 (manufacturer: General Electric), SLM-55067 (manufacturer: Wacker), and Abil*-Quat 3270 and 3272 (manufacturer: Th. Goldschmidt; diquaternary polydimethylsiloxanes, Quaternium 80), - polymeric dimethyl diallyl ammonium salts and their copolymers with esters and amides of acrylic acid and methacrylic acid. the 9 H06592 commercially available products Merquat*100 (poly(dimethyl diallyl ammonium chloride)) and Merquat*550 (dimethyl diallyl ammonium chloride-acrylamide copolymer) are examples of such cationic polymers. - copolymers of vinyl pyrrolidone with quaternized derivatives of dialkylamino acrylate and dialkylamino methacrylate, such as, for example vinyl pyrrolidone-dimethylaminoethyl methacrylate copolymers quaternized with diethyl sulfate. Such compounds are commercially available under the trade names Gafquat*734 and Gafquat*755. - vinyl pyrrolidone-vinyl imidazolium methochloride copolymers, as are offered under the trade names Luviquat@ FC 370, FC 550, FC 905 and HM 552, - quaternized polyvinyl alcohol and also the polymers known under the designations - Polyquaternium 2, - Polyquaternium 17, - Polyquaternium 18 and - Polyquaternium 27 known polymers having quaternary nitrogen atoms in the polymer main chain. [0036] Polymers designated as Polyquaternium-24 (commercial product e.g. Quatrisoft* LM 200) can also be employed as cationic polymers. The copolymers of vinyl pyrrolidone are also usable according to the invention, such as the commercially available products Copolymer 845 (manufacturer: ISP), Gaffix* VC 713 (manufacturer: ISP), Gafquat*ASCP 1011, Gafquat*HS 110, Luviquat*8155 and Luviquat* MS 370. [0037] Further inventive cationic polymers are the "temporarily cationic" polymers. These polymers usually comprise an amino group that is present at specific pH values as the quaternary ammonium group and is thus cationic. Chitosan and its derivatives, such as for example the 10 H06592 commercially available Hydagen* CMF, Hydagen* HCMF, Kytamer* PC and Chitolam* NB/101 are preferred. Chitosans are deacetylated chitins that are commercially available with various degrees of deactylation and various degrees of degradation (molecular weights). Their manufacture is described, for example in DE 44 40 625 Al and in DE 1 95 03 465 Al. [0038] Particularly well-suited chitosans have a deacetylation degree of at least 80 % and a molecular weight of 5 x 105 to 5 x 106 (g/mol). [0039] The chitosan has to be converted into the salt form for the manufacture of the inventive preparations. This can be effected by dissolution in dilute aqueous acids. Both mineral acids, such as e.g. hydrochloric acid, sulfuric acid and phosphoric acid and also organic acids, such as e.g. low molecular weight carboxylic acids, polycarboxylic acids and hydroxycarboxylic acids are suitable acids. Moreover, higher molecular weight alkyl sulfonic acids or alkyl sulfuric acids or organophosphoric acids can also be used, when they possess the required physiological compatibility. Suitable acids for converting chitosan into the salt form are e.g. acetic acid, glycolic acid, tartaric acid, malic acid, citric acid, lactic acid, 2-pyrollidinone-5-carboxylic acid, benzoic acid or salicylic acid. Low molecular weight hydroxycarboxylic acids are preferably used, such as e.g. glycolic acid or lactic acid. [00401 Particularly preferred cationic polymers are Polyquaternium-7 (Merquat 550), Polyquaternium-6, Polyquaternium-10 as well as all cationic Guar* derivatives. [0041] They are preferably incorporated in the compositions according to the invention in amounts of 0.1 to 5 wt.%, based on the total composition. Quantities of 0.2 to 3 wt.%, particularly 0.5 to 2 wt.%, are particularly preferred. 11 H06592 [0042] In a further preferred embodiment of the invention, the bath foam concentrates comprise a further surfactant. They can be selected from anionic, zwitterionic or amphoteric, non-ionic or cationic surfactants. Suitable anionic surfactants for the inventive preparations are all anionic surface-active materials that are suitable for use on the human body. They are characterized by a water solubilizing anionic group, such as e.g. a carboxylate, sulfate, sulfonate or phosphate group, and a lipophilic alkyl group containing about 8 to 30 carbon atoms. In addition, the molecule may comprise glycol or polyglycol ether groups, ester, ether and amide groups as well as hydroxyl groups. Exemplary suitable anionic surfactants are, each in the form of the sodium, potassium and ammonium as well as the mono, di and trialkanolammonium salts with 2 to 4 carbon atoms in the alkanol group, - linear and branched fatty acids containing 8 to 30 carbon atoms (soaps), - ether carboxylic acids of the formula R-O-(CH 2

In the context of the invention, typical examples of suitable monoglyceride (ether) sulfates are the reaction products of lauric acid monoglyceride, cocoa fatty acid monoglyceride, palmitic acid monoglyceride, stearic acid monoglyceride, oleic acid monoglyceride and tallow fatty acid monoglyceride as well as their ethylene oxide adducts with sulfur trioxide or chlorosulfonic acid in the form of their sodium salts. Preferably, monoglyceride sulfates of Formula (VIII) are added, in which R 13 CO stands for a linear acyl group with 8 to 18 carbon atoms. [0043] Preferred anionic surfactants are salts of ether carboxylic acids with 10 to 18 carbon atoms in the alkyl group and up to 12 glycol ether groups in the molecule, sulfosuccinic acid mono and dialkyl esters with 8 to 18 carbon atoms in the alkyl group and sulfosuccinic acid mono-alkyl polyoxyethyl esters with 8 to 18 C atoms in the alkyl group and 1 to 6 oxyethylene groups. [0044] Zwitterionic surfactants are designated as those surface-active compounds that carry at least one quaternary ammonium group and at least one -COOn or -SO3 group in the molecule. Particularly suitable zwitterionic surfactants are the so-called betaines such as the N-alkyl N,N-dimethylammonium glycinates, for example the 14 H06592 cocoalkyldimethylammonium glycinate, N-acylaminopropyl-N,N dimethylammonium glycinates, for example the cocoacylaminopropyldimethylammonium glycinate, and 2-alkyl-3 carboxymethyl-3-hydroxyethyl imidazolines with 8 to 18 carbon atoms in each of the alkyl or acyl groups, as well as cocoacylam inoethylhyd roxyethylcarboxymethyl glycinate. A preferred zwitterionic surfactant is the fatty acid amide derivative, known under the INCI name cocamidopropyl betaine. [0045] The ampholytic surfactants are understood to include such surface-active compounds that apart from a C8 - C24 alkyl or acyl group, comprise at least one free amino group and at least one -COOH or -SO 3 H group in the molecule, and are able to form internal salts. Examples of suitable ampholytic surfactants are N-alkylglycines, N-alkylamino propionic acids, N-alkylamino butyric acids, N-alkylimino dipropionic acids, N hydroxyethyl-N-alkylamidopropylglycine, N-alkyltaurines,

N

alkylsarcosines, 2-alkylamino propionic acids and alkylamino acetic acids, each with about 8 to 24 carbon atoms in the alkyl group. Particularly preferred ampholytic surfactants are N-cocoalkylamino propionate, cocoacylaminoethylamino propionate and C12-C18 acyl sarcosine. [0046] Non-ionic surfactants comprise e.g. a polyol group, a polyalkylene glycol ether group or a combination of polyol and polyglycol ether groups as the hydrophilic group. Exemplary compounds of this type are - methyl or C2-C alkyl group end blocked addition products of 2 to 50 moles ethylene oxide and/or 0 to 5 moles propylene oxide to linear and branched fatty alcohols with 8 to 30 carbon atoms, to fatty acids with 8 to 30 carbon atoms and to alkyl phenols with 8 to 15 carbon atoms in the alkyl group, such as, for example, the 15 H06592 commercially available types Dehydol* LS, Dehydol@ LT (Cognis), - C 12

[0047] Preparations with excellent properties are also obtained when they comprise fatty acid esters of ethoxylated glycerine as the non-ionic surfactant. 16 H06592 [0048] These compounds are characterized by the following parameters. The alkyl group R comprises 6 to 22 carbon atoms and may be both linear and also branched. Primary linear aliphatic groups and aliphatic groups that are methyl-branched in the 2-position, are preferred. Such alkyl groups are for example 1-octyl, 1-decyl, 1-lauryl, 1-myristyl, 1-cetyl and 1-stearyl. 1-Octyl, 1-decyl, 1-lauryl, 1-myristyl are particularly preferred. On using so-called "oxo alcohols" as starting materials, compounds with an odd number of carbon atoms in the alkyl chain preponderate. [0049] For compounds with alkyl groups that are used as surfactants, they may each be pure substances. However, it is normally preferred to start with natural vegetal or animal raw materials for the manufacture of these materials, with the result that mixtures of substances are obtained, which have different alkyl chain lengths that depend on each raw material. [0050] In the context of the invention, cationic surfactants are selected from quaternary ammonium compounds, esterquats and/or amido amines. [0051] Preferred quaternary ammonium compounds are ammonium halides, particularly chlorides and bromides, such as alkyl trimethyl ammonium chloride, dialkyl dimethyl ammonium chloride and trialkyl methyl ammonium chlorides, e.g. cetyl trimethyl ammonium chloride, stearyl trimethyl ammonium chloride, distearyl dimethyl ammonium chloride, lauryl dimethyl ammonium chloride, lauryl dimethyl benzyl ammonium chloride and tricetyl methyl ammonium chloride, as well as the imidazolium compounds known under the INCI names Quaternium-27 and Quaternium-83. The long alkyl chains of the abovementioned surfactants have preferably 10 to 18 carbon atoms. [0052] Esterquats are known compounds, which both comprise at least one ester function and also a quaternary ammonium group as structural 17 H06592 elements. Preferred esterquats are quaternized ester salts of fatty acids with triethanolamine, quaternized ester salts of fatty acids with diethanolalkylamines and quaternized ester salts of fatty acids with 1,2 dihydroxypropyldialkylamines. Such products are marketed, for example, under the trade names Stepantex*, Dehyquart* and Armocare*. The products Armocare® VGH-70, an N,N-bis(2-palmitoyloxyethyl)dimethyl ammonium chloride, as well as Dehyquart* F-75, Dehyquart* C-4046, Dehyquart* L80 and Dehyquart* AU 35 are examples of such esterquats.

[0068] These silicones are designated according to the INCI nomenclature as Amodimethicones. [0069] Independently of which aminofunctional silicone is added, inventive hair conditioners are preferred that comprise an aminofunctional silicone whose amine number is above 0.25 meq/g, preferably above 0.3 meq/g and particularly above 0.4 meq/g. The amine number stands for the milliequivalents of amine per gram of aminofunctional silicone. It can be measured by titration and is also reported with the unit mg KOH/g.

H06592 [0070] According to the invention, preferred hair conditioners are characterized in that they comprise, based on their weight, 0.01 to 10 wt.%, preferably 0.1 to 8 wt.%, particularly preferably 0.25 to 7.5 wt.% and particularly 0.5 to 5 wt.% aminofunctional silicone(s). [0071] Also, according to the invention, the addition of cyclic dimethicones, designated by INC as CYCLOMETHICONES, is preferred. Here, inventive hair conditioners are preferred that comprise at least one silicone of Formula IlIl 0-SiuCH.AbL- (111) in which x stands for a number from 0 to 200, advantageously from 0 to 10, more preferably from 0 to 7 and especially 0, 1, 2, 3, 4, 5 or 6. [0072] The above-described silicones possess a backbone that is constructed from -Si-O-Si- units. Of course, these Si-O-Si units can also be interrupted by carbon chains. Appropriate molecules are obtained by chain extension reactions and are preferably employed in the form of silicone in water emulsions. [0073] The silicone in water emulsions that are added according to the invention can be prepared by means of known processes, as disclosed, for example in US 5,998,537 and EP 0 874 017 Al. [0074] In summary, this manufacturing process includes the emulsifiable mixture of components, one comprising at least one polysiloxane, the other comprising at least one organosilicon material that reacts with the polysiloxane in a chain extension reaction, wherein at least one chain extension reaction catalyst that contains a metal ion is present, as well as a surfactant and water.

H06592 [0075] Chain extension reactions with polysiloxanes are known and can include, for example, the hydrosilylation reaction, in which a Si-H group is reacted with an aliphatic unsaturated group in the presence of a platinum/rhodium catalyst to yield polysiloxanes with several Si-(C)p-Si bonds (p = 1-6), the polysiloxanes being also designated as polysiloxane-polysilalkylene copolymers. [0076] The chain extension reaction can also include the reaction of an Si-OH group (for example a hydroxyl terminated polysiloxane) with an alkoxy group (for example alkoxy silanes, silicates or alkoxysiloxanes) in the presence of a metal-containing catalyst to afford polysiloxanes. [0077] The polysiloxanes that are employed in the chain extension reaction include a substantially linear polymer of the following structure: R-Si(R2)-[0-Si(R2)]n-0-SiR3 In this structure, each R independently of each other stands for a hydrocarbon group with up to 20 carbon atoms, preferably with 1 to 6 carbon atoms, such as, for example, an alkyl group (for example methyl, ethyl, propyl or butyl), an aryl group (for example phenyl), or the group required for the chain extension reaction ("reactive group", for example Si bonded hydrogen atoms, aliphatic unsaturated groups like vinyl, allyl or hexenyl, hydroxy, alkoxy such as methoxy, ethoxy or propoxy, alkoxy alkoxy, acetoxy, amino etc.) with the proviso that on average, one or two reactive groups per polymer are present, n is a positive number > 1. Preferably, a majority of the reactive groups, particularly preferably > 90%, and in particular > 98% of the reactive groups, is bonded to the terminal Si atom in the siloxane. Preferably, n stands for numbers that describe polysiloxanes with viscosities between 1 and 1 000 000 mm 2 /s, particularly preferably viscosities between 1000 and 100 000 mm 2 /s.

H06592 [0078] The polysiloxanes can be branched to a small extent (for example < 2 mol% of the siloxane units), or the polymers are substantially linear, particularly preferably completely linear. In addition, the substituents R can themselves be substituted, for example by N-containing groups (for example amino groups), epoxy groups, S-containing groups, Si containing groups, 0-containing groups etc.. Preferably, at least 80% of the R groups are alkyl groups, particularly preferably methyl groups. [0079] The organosilicon material that reacts with the polysiloxane in the chain extension reaction can either be a second polysiloxane, or a molecule that acts as a chain extender. If the organosilicon material is a polysiloxane, then it has the abovementioned general structure. In these cases one polysiloxane possesses (at least) one reactive group in the reaction, and a second polysiloxane possesses (at least) one second reactive group that reacts with the first. [0080] When the organosilicon material includes a chain extender, then this can be a material such as, for example a silane, a siloxane (for example disiloxane or trisiloxane) or a silazane. Thus, for example, a composition that includes a polysiloxane according to the above-described general structure, which possesses at least one Si-OH group, can be chain extended by its reaction with an alkoxy silane (for example a dialkoxy silane or trialkoxy silane) in the presence of a tin- or titanium-containing catalyst. [0081] The metal-containing catalysts in the chain extension reaction are mostly specific for a particular reaction. Such catalysts are known from the prior art and comprise, for example, metals like platinum, rhodium, tin, titanium, copper, lead, etc.. In a preferred chain extension reaction, a polysiloxane having at least one aliphatic unsaturated group, preferably an end group, is reacted in the presence of a hydrosilylation catalyst with H06592 an organosilicon material that is a siloxane or polysiloxane having at least one (preferably terminal) Si-H group. The polysiloxane possesses at least one aliphatic unsaturated group and satisfies the abovementioned general formula, in which R and n are as previously defined, wherein on average, between 1 and 2 R groups per polymer possess an aliphatic unsaturated group. Representative aliphatic unsaturated groups are, for example, vinyl, allyl, hexenyl and cyclohexenyl or a group R 2

CH=CHR

3 , in which R 2 stands for a divalent aliphatic chain bonded to the silicon and R 3 stands for a hydrogen atom or an alkyl group. The organosilicon material having at least one Si-H group has preferably the above cited structure, in which R and n are as previously defined, wherein on average, between I and 2 R groups mean a hydrogen and n is 0 or a positive number. [0082] This material can be a polymer or a low molecular weight material like a siloxane (for example a disiloxane or a trisiloxane). [0083] The polysiloxane, having at least one aliphatic unsaturated group, and the organosilicon group, having at least one Si-H group, react in the presence of a hydrosilylation catalyst. Such catalysts are known from the prior art and include, for example, platinum- and rhodium-containing materials. The catalysts can be in any known form, for example platinum or rhodium deposited on carrier materials (for example silica gel or active charcoal) or other suitable compounds like platinum chloride, salts of platinic acid or chloroplatinic acids. Due to its good dispersibility in organosilicon systems and to the low color changes, a preferred catalyst is chloroplatinic acid, either as the commercially available hexahydrate or in anhydrous form. [0084] In a further preferred chain extension reaction, a polysiloxane having at least one Si-OH group, preferably an end group, is reacted with an organosilicon material that has at least one alkoxy group, preferably a H06592 siloxane having at least one Si-OR group or an alkoxy silane having at least two alkoxy groups. Again, a metal-containing catalyst is again used as the catalyst here. [0085] For the reaction between an Si-OH group with an Si-OR group, there exist many catalysts known from the literature, for example, organometallic compounds like organotin salts, titanates or titanium chelates or complexes. Examples include tin-octoate, dibutyltin dilaurate, dibutyltin diacetate, dimethyltin dineodecanoate, dibutyltin dimethoxide, isobutyltin triceroate, dimethyltin dibutyrate, dimethyltin dineodecanoate, triethyltin tartrate, tin oleate, tin naphthenate, tin butyrate, tin acetate, tin benzoate, tin sebacate, tin succinate, tetrabutyltitanate, tetraisopropyltitanate, tetraphenyltitanate, tetraoctadecyltitanate, titanium naphthenate, ethyltriethanolamine titanate, titanium diisopropyl diethyl acetoacetate, titanium diisopropoxy diacetyl acetonate und titanium tetraalkoxide, in which the alkoxide is butoxy or propoxy. [0086] Furthermore, the silicone in water emulsions preferably comprise at least one surfactant. They were described in detail above. [0087] Likewise preferred inventive bath foam concentrates are characterized in that they comprise at least one silicone of Formula (IV) R3Si-[0-SiR2]r-(CH2)n-[0-SiR2]y-0-SiR3 (IV), in which R stands for the same or different groups from the group -H, phenyl, -benzyl, -CH 2

Oa H06592 [0088] Preferably, the silicones of the inventive cleaning agent are water insoluble. According to the invention, preferred hair conditioners are thus characterized in that they may further comprise a water-soluble silicone. [0089] According to the invention, particularly preferred silicone compounds are water-insoluble dimethicones and dimethiconols. [0090] In addition, a dialkyl ether can serve as the oil component. [0091] Dialkyl ethers suitable for use in accordance with invention are particularly di-n-alkyl ethers containing a total of 12 to 36 carbon atoms and, more particularly 12 to 24 carbon atoms such as, for example, di-n octyl ether, di-n-decyl ether, di-n-nonyl ether, di-n-undecyl ether, di-n dodecyl ether, n-hexyl n-octyl ether, n-octyl n-decyl ether, n-decyl n undecyl ether, n-undecyl n-dodecyl ether and n-hexyl n-undecyl ether and di-tert.butyl ether, diisopentyl ether, di-3-ethyldecyl ether, tert.-butyl n-octyl ether, isopentyl n-octyl ether and 2-methylpentyl n-octyl ether. [0092] Di-n-octyl ether, obtainable as the commercial product Cetiol* OE, is particularly preferred according to the invention. [0093] In a further preferred embodiment of the invention, the action of the inventive combination of active principles can be even further optimized by means of additional fats. Additional fats are understood to mean fatty acids, fatty alcohols as well as natural and synthetic waxes that can be both in solid form as well as liquid in aqueous dispersion. [0094] Linear and/or branched, saturated and/or unsaturated fatty acids having 6 - 30 carbon atoms can be used as the fatty acids. Fatty acids containing 10-22 carbon atoms are preferred. Among these may be cited the isostearic acids, such as the commercial products Emersol* 871 and H06592 Emersol@ 875, and isopalmitic acids such as the commercial product Edenor* IP 95, as well as all other fatty acids commercialized under the trade names Edenor* (Cognis). Further typical examples of such fatty acids are caproic acid, caprylic acid, 2-ethylhexanoic acid, capric acid, lauric acid, isotridecanoic acid, myristic acid, palmitic acid, palmitoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, petroselic acid, linoleic acid, linolenic acid, elaeostearic acid, arachidonic acid, gadoleic acid, behenic acid and erucic acid as well as their technical mixtures, that e.g. result from cracking of natural fats and oils, from the oxidation of aldehydes from Roelen's oxo synthesis or the dimerization of unsaturated fatty acids. Usually, the fatty acid fractions obtainable from coconut oil and palm oil are particularly preferred; in general, the addition of stearic acid is particularly preferred. [0100] As fatty alcohols, saturated, mono or polyunsaturated, branched or linear fatty alcohols containing C6 to C30-, preferably C10 to C22- and quite particularly preferably C12 to C22- carbon atoms can be added.

However, the fatty alcohols are preferably derived from naturally occurring fatty acids, usually obtained by reducing the fatty acid esters. Likewise, according to the invention, those fatty alcohols can be added that are obtained by reducing naturally occurring triglycerides like beef tallow, palm oil, peanut oil, oil of rapeseed, cotton seed oil, soya oil, sunflower oil and linen oil, or the fatty acid esters produced from their transesterification products with appropriate alcohols, thereby producing a mixture of different fatty alcohols. Such substances can be bought, for example, under the trade names Stenol*, e.g. Stenol* 1618 or Lanette*, H06592 e.g. Lanette* 0 or Lorol@, e.g. Lorol* C8, Lorol@ C14, Lorol® C18, Lorol@ C8-18, HD-Ocenol@, Crodacol@, e.g. Crodacol@ CS, Novol@, Eutanol* G, Guerbitol@ 16, Guerbitol® 18, Guerbitol@ 20, Isofol® 12, Isofol® 16, Isofol@ 24, Isofol@ 36, Isocarb@ 12, Isocarb@ 16 or lsocarb@ 24. Of course, wool wax alcohols such as those that are commercially available for example, under the trade names Corona*, White Swan*, Coronet* or Fluilan@ can also be added according to the invention. [0101] According to the invention, solid paraffins or isoparaffins, carnuba wax, beeswax, candelilla wax, ozocerite, ceresine, sperm wax, sunflower wax, fruit waxes such as for example apple wax or citrus wax, microwaxes of PE or PP can be added as the natural or synthetic waxes. These types of waxes are available, for example, from Kahl & Co., Trittau. [0102] Further fats are for example - Ester oils. Ester oils are understood to mean the esters of C6 C30 fatty acids with C2 - C30 fatty alcohols. Monoesters of fatty acids with alcohols having 2 to 24 carbon atoms are preferred.

The inventive cationic derivatives based on protein hydrolyzates can be obtained from the corresponding proteins by a chemical, particularly alkaline or acid hydrolysis, by an enzymatic hydrolysis and/or a combination of both types of hydrolysis. The hydrolysis of proteins generally produces a protein hydrolyzate with a molecular weight distribution from about 100 daltons up to several thousand daltons. Cationic protein hydrolyzates are preferred, whose base protein content has a molecular weight of 100 to 25000 daltons, preferably 250 to 5000 daltons. Moreover, cationic protein hydrolyzates are understood to include quaternized amino acids and their mixtures. Quaternization of the protein hydrolyzates or of the amino acids is often carried out using quaternary ammonium salts such as, for example, N,N-dimethyl-N-(n-alkyl)-N-(2-hydroxy-3-chloro-n-propyl) ammonium halides. Moreover, the cationic protein hydrolyzates can also be further derivatized. Typical examples of inventive cationic protein hydrolyzates and derivatives are the commercially available products and H06592 those cited under the INCI names in the "International Cosmetic Ingredient Dictionary and Handbook", (seventh edition 1997, The Cosmetic, Toiletry, and Fragrance Association 1101 17 th Street, N.

H06592 [0119] Usually, these extracts are manufactured by extraction of the whole plant. In individual cases, however, it can also be preferred to manufacture the extracts solely from blossoms and/or leaves of the plant. [0120] The extracting agent used to prepare the cited plant extracts can be water, alcohols as well as their mixtures. Exemplary preferred alcohols are lower alcohols such as ethanol and isopropanol, but particularly polyhydroxy alcohols such as ethylene glycol, propylene glycol and butylene glycol, both as the sole extracting agent as well as in aqueous mixtures. Plant extracts based on water/propylene glycol in the ratio 1: 10 to 10: 1 have proven particularly suitable. [0121] According to the invention, the plant extracts can be used in pure and also in diluted form. When they are used in diluted form, they normally comprise ca. 2 - 80 wt.% active substance and the solvent is the extracting agent or mixture of extracting agents used for their preparation. [0122] The plant extracts are incorporated in bath foam concentrates - based on their weight - in an amount from 0.01 to 5 wt.%, preferably 0.02 to 4 wt.% and particularly 0.05 to 3 wt.%. [0123] In addition, in a preferred embodiment of the invention, the effect of the inventive composition can be augmented by UV filters (1).

Al H06592 [0127] Those UV filters with a molecular extinction coefficient at the absorption maximum of above 15 000, particularly 20 000, are preferred. [0128] Moreover, it was found that for structurally similar UV filters, in many cases in the context of the inventive teaching, the water-insoluble compound exhibits a higher activity than that of water-soluble compounds that differ from them by one or a plurality of additional ionic groups. In the context of the invention, water-insoluble UV filters are understood to mean those that do not dissolve more than 1 wt.%, especially not more than 0.1 wt.% in water at 20 *C. In addition, these compounds should be soluble to at least 0.1, especially to at least 1 wt.% in conventional cosmetic oil components at room temperature. Accordingly, the use of water-insoluble UV filters can be inventively preferred. [0129] According to a further embodiment of the invention, those UV filters are preferred, which have a cationic group, especially a quaternary ammonium group. These UV filters have the general structure U-Q. [0130] Here, the structural component U stands for a group that absorbs UV radiation. In principle, these groups can derive from the known abovementioned UV filters that can be employed in the field of cosmetics, in which one group, generally a hydrogen atom of the UV filter is replaced by a cationic group Q, in particular with a quaternary amino function. [0131] Compounds, from which the structural component U can derive are for example - - substituted benzophenones, - - p-aminobenzoic acid esters, - - diphenylacrylic acid esters, H06592 - - cinnamic acid esters, - - salicylic acid esters, - - benzimidazoles and - - o-aminobenzoic acid esters. [0132] Structural components U that derive from cinnamic acid amide or from N,N-dimethylaminobenzoic acid amide are inventively preferred. [0133] In principle, the structural components U can be selected such that the absorption maximum of the UV filter can be in the UVA (315-400 nm) region, as well as in the UVB(280-315) region or in the UVC(<280 nm) region. UV filters having an absorption maximum in the UVB region, especially in the range from about 280 to about 300 nm, are particularly preferred. [0134] Furthermore, the structural component U, also depending on the structural component Q, is preferably selected such that the molar extinction coefficient of the UV filter at the absorption maximum is above 15 000, especially above 20 000. [0135] The structural component Q preferably comprises a quaternary ammonium group as the cationic group. In principle, this quaternary ammonium group can be directly bonded to the structural component U, such that the structural component U represents one of the four substituents of the positively charged nitrogen atom. Preferably however, one of the four substituents on the positively charged nitrogen atom is a group, in particular an alkyl group containing 2 to 6 carbon atoms, which acts as the link between the structural component U and the positively charged nitrogen atom. [0136] Advantageously, the group Q has the general structure -(CH 2 )x

[0138] Two preferred UV filters containing cationic groups are the compounds cinnamic acid amidopropyl trimethyl ammonium chloride (Incroquat@ UV 283) and dodecyl dimethylaminobenzamidopropyl dimethyl ammonium tosylate (Escalol® HP 610). [0139] Of course, the inventive teaching also includes the use of a combination of a plurality of UV filters. In the context of this embodiment, the combination of at least one water-insoluble UV filter with at least one UV filter containing a cationic group is preferred. [0140] The bath foam concentrates according to the invention usually comprise the UV filters (1) in quantities of 0.01 to 5 wt.%, based on the total composition. Quantities of 0.05-2.0 wt.% are preferred. [0141] In addition to the inventively mandatory components and the abovementioned, further preferred components, the inventive compositions can, in principle, comprise all additional components for such cosmetic compositions which are known to the person skilled in the art.
