Title: Water-based cleansing compositions

Description:
BACKGROUND OF THE INVENTION  
       [0001] This invention relates generally to cosmetic cleansing compositions and more particularly to new preparations which may be used in particular as dermatologically mild hand washing paste concentrates and may contain fatty acid alkyl esters and emulsifiers together with other auxiliaries and additives.  
       [0002] Skin cleansers are generally more or less concentrated emulsions which, besides a cosmetic oil component, also contain above all surfactants and skin care agents. Consumers prefer cleansers which not only show particular dermatological compatibility, but also remove oily soils in particular-including decorative cosmetics in the broadest sense-both quickly and completely. In many cases, manufacturers of such preparations tend not to mix the individual components themselves, preferring to resort to so-called multipurpose compounds. These are intermediate products of two or more constituents which have a high active substance content and which may be used as a base for very different end products, for example o/w emulsions containing oil, water and an emulsifier. In the most simple case, the concentrates are diluted with water to the required concentration and then themselves represent the preparation. In general, however, appropriate additives are incorporated in them. The compounds are of course expected to meet the same requirements as the dilutions. However, the intermediate products are also expected to have special features, for example a uniform and fine dispersion of the oil droplets in the water phase, and to be stable in storage and heat-resistant.  
       [0003] Accordingly, the problem addressed by the present invention was to provide fine-particle water-containing concentrates for the production of cleansing compositions, more particularly hand washing pastes, which would be effective in particular against oily soil types. The concentrates would be flowable as superconcentrates, dermatologically safe and stable in storage, i.e. would have no tendency towards phase separation or gelation even when stored at elevated temperatures.  
       BRIEF SUMMARY OF THE INVENTION  
       [0004] The present invention is directed to an aqueous cleaning concentrate containing: (a) from about 20 to about 40% by weight of a fatty acid alkyl ester; and (b) from about 5 to about 20% by weight of an emulsifier, all weights being based on the total weight of the concentrate, and wherein the concentrate is in the form of a PIT emulsion with droplets having a mean diameter of below about 50μm.  
       [0005] The present invention is also directed to a process for removing oily soil from a substrate involving contacting the oily soil with a cleaning concentrate containing: (i) from about 20 to about 40% by weight of a fatty acid alkyl ester; and (ii) from about 5 to about 20% by weight of an emulsifier, all weights being based on the total weight of the concentrate, and wherein the concentrate is in the form of a PIT emulsion with droplets having a mean diameter of below about 50μm. 
     
    
    
     DETAILED DESCRIPTION OF THE INVENTION  
     [0006] All numbers expressing quantities of ingredients and/or reaction conditions are to be understood as being modified in all instance by the term “about”.  
     [0007] It has surprisingly been found that fatty acid alkyl esters can be processed in the presence of emulsifiers to form highly concentrated emulsions of low water content which are additionally distinguished by the fact that they are made up of very fine droplets, are stable in storage, heat-resistant and mild to the skin and in addition are highly detersive, particularly towards oily soil types.  
     [0008] Fatty Acid Alkyl Esters  
     [0009] Fatty acid alkyl esters suitable as component (a) are reaction products of fatty acids with lower aliphatic alcohols which, alternatively, may also be obtained by transesterification of natural or synthetic fats and oils. They preferably correspond to formula (I): 
     R 1 CO—OR 2    (I) 
     [0010] in which R 1 CO is a linear or branched, saturated and/or unsaturated acyl group containing 6 to 22 carbon atoms and R 2  is an alkyl group containing 1 to 4 carbon atoms, more particularly a methyl group. Typical examples are the methyl, ethyl, propyl or butyl esters of caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, palmitoleic acid, stearic acid, isostearic acid, oleic acid, elaidic acid, linoleic acid, linolenic acid, gadoleic acid, arachidonic acid, behenic acid and erucic acid and technical mixtures thereof Preferred fatty acid esters are those derived from unsaturated fatty acids, for example soya, sunflower or rapeseed oil fatty acid which have iodine values in the range from 90 to 190 and preferably in the range from 100 to 120.  
     [0011] Emulsifiers  
     [0012] Suitable emulsifiers which form component (b) are, in particular, nonionic surfactants from at least one of the following groups:  
     [0013] products of the addition of 2 to 50 moles of ethylene oxide and/or 0 to 5 moles of propylene oxide onto linear C 8-22  fatty alcohols, C 12-22  fatty acids and alkyl phenols containing 8 to 15 carbon atoms in the alkyl group and alkylamines containing 8 to 22 carbon atoms in the alkyl group;

     [0027] The addition products of ethylene oxide and/or propylene oxide with fatty alcohols, fatty acids, alkylphenols or with castor oil are known commercially available products. They are homolog mixtures of which the average degree of alkoxylation corresponds to the ratio between the quantities of ethylene oxide and/or propylene oxide and substrate with which the addition reaction is carried out. Products of the addition of 5 to 50 and preferably 10 to 20 moles ethylene oxide onto C 12-18  fatty alcohols or hydrogenated castor oil are particularly preferred. C 12/18  fatty acid monoesters and diesters of adducts of ethylene oxide with glycerol are known as refatting agents for cosmetic formulations from DE 2024051 PS.  
     [0028] Alkyl and alkenyl oligoglycosides are known nonionic surfactants which correspond to formula (II): 
     R 3 O—[G] q    (II) 
     [0029] where R 3  is an alkyl and/or alkenyl group containing 4 to 22 carbon atoms, G is a sugar unit containing 5 or 6 carbon atoms and q is a number of 1 to 10. They may be obtained by the relevant methods of preparative organic chemistry. EP-A1-0 301 298 and WO 90/03977 are cited here as representative of the literature abundantly available on the subject. The alkyl and/or alkenyl oligoglycosides may be derived from aldoses or ketoses containing 5 or 6 carbon atoms, preferably glucose. Accordingly, the preferred alkyl and/or alkenyl oligoglycosides are alkyl and/or alkenyl oligoglucosides. The index q in general formula (II) indicates the degree of oligomerization (DP), i.e. the distribution of mono- and oligoglycosides, and is a number of 1 to 10. Whereas q in a given compound must always be an integer and, above all, may assume a value of 1 to 6, the value q for a certain alkyl oligoglycoside is an analytically determined calculated quantity which is generally a broken number. Alkyl and/or alkenyl oligoglycosides having an average degree of oligomerization q of 1.1 to 3.0 are preferably used. Alkyl and/or alkenyl oligoglycosides having a degree of oligomerization of less than 1.7 and, more particularly, between 1.2 and 1.4 are preferred from the applicational perspective. The alkyl or alkenyl group R 3  may be derived from primary alcohols containing 4 to 11 and preferably 8 to 10 carbon atoms. Typical examples are butanol, caproic alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and the technical mixtures thereof obtained, for example, in the hydrogenation of technical fatty acid methyl esters or in the hydrogenation of aldehydes from Roelen&#39;s oxosynthesis. Alkyl oligoglucosides having a chain length of C 8  to C 10  (DP=1 to 3), which are obtained as first runnings in the separation of technical C 8-18  coconut oil fatty alcohol by distillation and which may contain less than 6% by weight of C 12  alcohol as an impurity, and also alkyl oligoglucosides based on technical C 9/11  oxoalcohols (DP=1 to 3) are preferred. In addition, the alkyl or alkenyl group R 3  may also be derived from primary alcohols containing 12 to 22 and preferably 12 to 14 carbon atoms. Typical examples are lauryl alcohol, myristyl alcohol, cetyl alcohol, palmitoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol, brassidyl alcohol and technical mixtures thereof which may be obtained as described above. Alkyl oligoglucosides based on hydrogenated C 12/14  coconut oil fatty alcohol having a DP of 1 to 3 are preferred. By virtue of their particular dermatological compatibility and excellent emulsifying and refatting properties, alkyl oligoglucosides are also particularly preferred constituents of the preparations according to the invention.  
     [0030] Typical examples of suitable partial glycerides are hydroxystearic acid monoglyceride, hydroxystearic acid diglyceride, isostearic acid monoglyceride, isostearic acid diglyceride, oleic acid monoglyceride, oleic acid diglyceride, ricinoleic acid monoglyceride, ricinoleic acid diglyceride, linoleic acid monoglyceride, linoleic acid diglyceride, linolenic acid monoglyceride, linolenic acid diglyceride, erucic acid monoglyceride, erucic acid diglyceride, tartaric acid monoglyceride, tartaric acid diglyceride, citric acid monoglyceride, citric acid diglyceride, malic acid monoglyceride, malic acid diglyceride and technical mixtures thereof which may still contain small quantities of triglyceride from the production process.

     [0033] Other suitable emulsifiers are zwitterionic surfactants. Zwitterionic surfactants are surface-active compounds which contain at least one quaternary ammonium group and at least one carboxylate and one sulfonate group in the molecule. Particularly suitable zwitterionic surfactants are the so-called betaines, such as the N-alkyl-N, N-dimethyl ammonium glycinates, for example cocoalkyl dimethyl ammonium glycinate, N-acylaminopropyl-N,N-dimethyl ammonium glycinates, for example coco-acylaminopropyl dimethyl ammonium glycinate, and 2-alkyl-3-carboxymethyl-3-hydroxyethyl imidazolines containing 8 to 18 carbon atoms in the alkyl or acyl group and cocoacylaminoethyl hydroxyethyl carboxymethyl glycinate. The fatty acid amide derivative known under the CTFA name of Cocamidopropyl Betaine is particularly preferred. Ampholytic surfactants are also suitable emulsifiers. Ampholytic surfactants are surface-active compounds which, in addition to a C 8/18  alkyl or acyl group, contain at least one free amino group and at least one —COOH —or —SO 3 H —group in the molecule and which are capable of forming inner salts.

     [0035] In one preferred embodiment of the present invention, the preparations may also contain refatting agents. Particularly suitable refatting agents are partial glycerides, i.e. monoglycerides, diglycerides and technical mixtures thereof which may still contain small quantities of triglycerides from their production. The partial glycerides preferably correspond to formula (III):  
                 
 
     [0036] in which R 4 CO is a linear or branched, saturated and/or unsaturated acyl group containing 6 to 22 and preferably 12 to 18 carbon atoms, R 5  and R 6  independently of one another have the same meaning as R 4 CO or represent OH and the sum (m+n+p) is 0 or a number of 1 to 100 and preferably 5 to 25, with the proviso that at least one of the two substituents R 5  and R 6  represents OH.

     [0063] Fats and Waxes  
     [0064] 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 such as, for example, candelilla wax, carnauba wax, Japan wax, espartograss wax, cork wax, guaruma wax, rice oil wax, sugar cane wax, ouricury wax, montan wax, beeswax, shellac wax, spermaceti, lanolin (wool wax), uropygial fat, ceresine, ozocerite (earth wax), petrolatum, paraffin waxes and microwaxes; chemically modified waxes (hard waxes) such as, for example, montan ester waxes, sasol waxes, hydrogenated jojoba waxes and synthetic waxes such as, for example, polyalkylene waxes and polyethylene glycol waxes. Besides the fats, other suitable additives are fat-like substances, such as lecithins and phospholipids. Lecithins are known among experts as glycerophospholipids which are formed from fatty acids, glycerol, phosphoric acid and choline by esterification. Accordingly, lecithins are also frequently referred to by experts as phosphatidyl cholines (PCs). Examples of natural lecithins are the kephalins which are also known as phosphatidic acids and which are derivatives of 1,2-diacyl-sn-glycerol-3-phosphoric acids. By contrast, phospholipids are generally understood to be mono- and preferably diesters of phosphoric acid with glycerol (glycerophosphates) which are normally classed as fats. Sphingosines and sphingolipids are also suitable.

Other suitable silicone compounds are simethicones which are mixtures of dimethicones with an average chain length of 200 to 300 dimethylsiloxane units and hydrogenated silicates. A detailed overview of suitable volatile silicones can be found in Todd et al. in Cosm. Toil. 91, 27 (1976).  
     [0078] UV Protection Factors and Antioxidants  
     [0079] UV protection factors in the context of the invention are, for example, organic substances (light filters) which are liquid or crystalline at room temperature and which are capable of absorbing ultraviolet or infrared radiation and of releasing the energy absorbed in the form of longer-wave radiation, for example heat. UV-B filters can be oil-soluble or water-soluble. The following are examples of oil-soluble substances:  
     [0080] benzylidene camphor or 3-benzylidene norcamphor and derivatives thereof, for example 3-(4-methylbenzylidene)-camphor as described in EP 0693471 B1;

     [0093] Typical UV-A filters are, in particular, derivatives of benzoyl methane such as, for example, 1-(4′-tert.butylphenyl)-3-(4′-methoxyphenyl)-propane-1, 3-dione, 4-tert.butyl4′-methoxydibenzoyl methane (PARSOLD 1789) or 1-phenyl-3-(4′-isopropylphenyl)-propane-1,3-dione and the eneamine compounds described in DE 19712033 Al (BASF). The UV-A and UV-B filters may of course also be used in the form of mixtures. Particularly favorable combinations consist of the derivatives of benzoylmethane, for example 4-tert.-butyl4′-methoxydibenzoyl methane (PARSOL® 1789) and 2-cyano-3,3-phenylcinnamic acid-2-ethylhexyl ester (Octocrylene) in combination with esters of cinnamic acid, preferably 4-methoxycinnamic acid-2-ethylhexyl ester and/or 4-methoxycinnamic acid propyl ester and/or 4-methoxycinnamic acid isoamyl ester. These combinations are advantageously combined with water-soluble filters such as, for example, 2-phenylbenzimidazole-5-sulfonic acid and alkali metal, alkaline earth metal, ammonium, alkylammonium, alkanolammonium and glucammonium salts.  
     [0094] Besides the soluble substances mentioned, insoluble light-blocking pigments, i.e. finely dispersed metal oxides or salts, may also be used for this purpose. Examples of suitable metal oxides are, in particular, zinc oxide and titanium dioxide and also oxides of iron, zirconium oxide, silicon, manganese, aluminum and cerium and mixtures thereof Silicates (talcum), barium sulfate and zinc stearate may be used as salts. The oxides and salts are used in the form of the pigments for skin-care and skin-protecting emulsions and decorative cosmetics.

They may be spherical in shape although ellipsoidal particles or other non-spherical particles may also be used. The pigments may also be surface treated, i.e. hydrophilicized or hydrophobicized. Typical examples are coated titanium dioxides, for example Titandioxid T 805 (Degussa) and EUSOLEX® T2000 (Merck). Suitable hydrophobic coating materials are, above all, silicones and, among these, especially trialkoxyoctylsilanes or simethicones. So-called micro- or nanopigments are preferably used in sun protection products. Micronized zinc oxide is preferably used. Other suitable UV filters can be found in P. Finkel&#39;s review in SÖFW-Journal 122, 543 (1996) and in Parf. Kosm. 3, 11 (1999).  
     [0095] Besides the two groups of primary sun protection factors mentioned above, secondary sun protection factors of the antioxidant type may also be used. Secondary sun protection factors of the antioxidant type interrupt the photochemical reaction chain which is initiated when UV rays penetrate into the skin. Typical examples are amino acids (for example glycine, histidine, tyrosine, tryptophane) and derivatives thereof, imidazoles (for example urocanic acid) and derivatives thereof, peptides, such as D,L-carnosine, D-carnosine, L-carnosine and derivatives thereof (for example anserine), carotinoids, carotenes (for example α-carotene, β-carotene, lycopene) and derivatives thereof, chlorogenic acid and derivatives thereof, liponic acid and derivatives thereof (for example dihydroliponic acid), aurothioglucose, propylthiouracil and other thiols (for example thioredoxine, glutathione, cysteine, cystine, cystamine and glycosyl, N-acetyl, methyl, ethyl, propyl, amyl, butyl and lauryl, palmitoyl, oleyl, γ-linoleyl, cholesteryl and glyceryl esters thereof) and their salts, dilaurylthiodipropionate, distearylthiodipropionate, thiodipropionic acid and derivatives thereof (esters, ethers, peptides, lipids, nucleotides, nucleosides and salts) and sulfoximine compounds (for example butionine sulfoximines, homocysteine sulfoximine, butionine sulfones, penta-, hexa- and hepta-thionine sulfoximine) in very small compatible dosages (for example pmole to mole/kg), also (metal) chelators (for example α-hydroxyfatty acids, palmitic acid, phytic acid, lactoferrine), α-hydroxy acids (for example citric acid, lactic acid, malic acid), humic acid, bile acid, bile extracts, bilirubin, biliverdin, EDTA, EGTA and derivatives thereof, unsaturated fatty acids and derivatives thereof (for example γ-linolenic acid, linoleic acid, oleic acid), folic acid and derivatives thereof, ubiquinone and ubiquinol and derivatives thereof, vitamin C and derivatives thereof (for example ascorbyl palmitate, Mg ascorbyl phosphate, ascorbyl acetate), tocopherols and derivatives (for example vitamin E acetate), vitamin A and derivatives (vitamin A palmitate) and coniferyl benzoate of benzoin resin, rutinic acid and derivatives thereof, α-glycosyl rutin, ferulic acid, furfurylidene glucitol, carnosine, butyl hydroxytoluene, butyl hydroxyanisole, nordihydroguaiac resin acid, nordihydroguaiaretic acid, trihydroxybutyrophenone, uric acid and derivatives thereof, mannose and derivatives thereof, Superoxid-Dismutase, zinc and derivatives thereof (for example ZnO, ZnSO 4 ), selenium and derivatives thereof (for example selenium methionine), stilbenes and derivatives thereof (for example stilbene oxide, trans-stilbene oxide) and derivatives of these active substances suitable for the purposes of the invention (salts, esters, ethers, sugars, nucleotides, nucleosides, peptides and lipids).

     [0098] Deodorants and Germ Inhibitors  
     [0099] Cosmetic deodorants counteract, mask or eliminate body odors. Body odors are formed through the action of skin bacteria on apocrine perspiration which results in the formation of unpleasant-smelling degradation products. Accordingly, deodorants contain active principles which act as germ inhibitors, enzyme inhibitors, odor absorbers or odor maskers. Basically, suitable germ inhibitors are any substances which act against gram-positive bacteria such as, for example, 4-hydroxybenzoic acid and salts and esters thereof, N-(4-chlorophenyl)-N′-(3,4-dichlorophenyl)-urea, 2,4, 4′-trichloro-2′-hydroxydiphenylether (triclosan), 4-chloro-3,5-dimethylphenol, 2, 2′-methylene-bis-(6-bromo-4-chlorophenol), 3-methyl4-(1-methylethyl)-phenol, 2-benzyl4-chlorophenol, 3-(4-chlorophenoxy)-propane-1,2-diol, 3-iodo-2-propinyl butyl carbamate, chlorhexidine, 3,4,4′-trichlorocarbanilide (TTC), antibacterial perfumes, thymol, thyme oil, eugenol, clove oil, menthol, mint oil, farnesol, phenoxyethanol, glycerol monocaprate, glycerol monocaprylate, glycerol monolaurate (GML), diglycerol monocaprate (DMC), salicylic acid-N-alkylamides such as, for example, salicylic acid-n-octyl amide or salicylic acid-n-decyl amide.  
     [0100] Suitable enzyme inhibitors are, for example, esterase inhibitors. Esterase inhibitors are preferably trialkyl citrates, such as trimethyl citrate, tripropyl citrate, triisopropyl citrate, tributyl citrate and, in particular, triethyl citrate (HYDAGEN® CAT). Esterase inhibitors inhibit enzyme activity and thus reduce odor formation. Other esterase inhibitors are sterol sulfates or phosphates such as, for example, lanosterol, cholesterol, campesterol, stigmasterol and sitosterol sulfate or phosphate, dicarboxylic acids and esters thereof, for example glutaric acid, glutaric acid monoethyl ester, glutaric acid diethyl ester, adipic acid, adipic acid monoethyl ester, adipic acid diethyl ester, malonic acid and malonic acid diethyl ester, hydroxycarboxylic acids and esters thereof, for example citric acid, malic acid, tartaric acid or tartaric acid diethyl ester, and zinc glycinate.  
     [0101] Suitable odor absorbers are substances which are capable of absorbing and largely retaining the odor-forming compounds. They reduce the partial pressure of the individual components and thus also reduce the rate at which they spread. An important requirement in this regard is that perfumes must remain unimpaired. Odor absorbers are not active against bacteria. They contain, for example, a complex zinc salt of ricinoleic acid or special perfumes of largely neutral odor known to the expert as “fixateurs” such as, for example, extracts of labdanum or styrax or certain abietic acid derivatives as their principal component. Odor maskers are perfumes or perfume oils which, besides their odor-masking function, impart their particular perfume note to the deodorants. Suitable perfume oils are, for example, mixtures of natural and synthetic fragrances. Natural fragrances include the extracts of blossoms, stems and leaves, fruits, fruit peel, roots, woods, herbs and grasses, needles and branches, resins and balsams. Animal raw materials, for example civet and beaver, may also be used. Typical synthetic perfume compounds are products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type. Examples of perfume compounds of the ester type are benzyl acetate, p-tert.butyl cyclohexylacetate, linalyl acetate, phenyl ethyl acetate, linalyl benzoate, benzyl formate, allyl cyclohexyl propionate, styrallyl propionate and benzyl salicylate. Ethers include, for example, benzyl ethyl ether while aldehydes include, for example, the linear alkanals containing 8 to 18 carbon atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamen aldehyde, hydroxycitronellal, lilial and bourgeonal. Examples of suitable ketones are the ionones and methyl cedryl ketone. Suitable alcohols are anethol, citronellol, eugenol, isoeugenol, geraniol, linalool, phenylethyl alcohol and terpineol. The hydrocarbons mainly include the terpenes and balsams. However, it is preferred to use mixtures of different perfume compounds which, together, produce an agreeable fragrance. Other suitable perfume oils are essential oils of relatively low volatility which are mostly used as aroma components. Examples are sage oil, camomile oil, clove oil, melissa oil, mint oil, cinnamon leaf oil, lime-blossom oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil, labolanum oil and lavendin oil. The following are preferably used either individually or in the form of mixtures: bergamot oil, dihydromyrcenol, lilial, lyral, citronellol, phenylethyl alcohol, α-hexylcinnamaldehyde, geraniol, benzyl acetone, cyclamen aldehyde, linalool, Boisambrene Forte, Ambroxan, indole, hedione, sandelice, citrus oil, mandarin oil, orange oil, allylamyl glycolate, cyclovertal, lavendin oil, clary 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, romillat, irotyl and floramat.  
     [0102] Antiperspirants reduce perspiration and thus counteract underarm wetness and body odor by influencing the activity of the eccrine sweat glands. Aqueous or water-free antiperspirant formulations typically contain the following ingredients:  
     [0103] astringent active principles,  
     [0104] oil components,  
     [0105] nonionic emulsifiers,  
     [0106] co-emulsifiers,  
     [0107] consistency factors,  
     [0108] auxiliaries in the form of, for example, thickeners or complexing agents and/or non-aqueous solvents such as, for example, ethanol, propylene glycol and/or glycerol.  
     [0109] Suitable astringent active principles of antiperspirants are, above all, salts of aluminum, zirconium or zinc. Suitable antihydrotic agents of this type are, for example, aluminum chloride, aluminum chlorohydrate, aluminum dichlorohydrate, aluminum sesquichlorohydrate and complex compounds thereof, for example with 1,2-propylene glycol, aluminum hydroxyallantoinate, aluminum chloride tartrate, aluminum zirconium trichlorohydrate, aluminum zirconium tetrachlorohydrate, aluminum zirconium pentachlorohydrate and complex compounds thereof, for example with amino acids, such as glycine. Oil-soluble and water-soluble auxiliaries typically encountered in antiperspirants may also be present in relatively small amounts. Oil-soluble auxiliaries such as these include, for example,  
     [0110] inflammation-inhibiting, skin-protecting or pleasant-smelling essential oils,  
     [0111] synthetic skin-protecting agents and/or  
     [0112] oil-soluble perfume oils.

Suitable polyols preferably contain 2 to 15 carbon atoms and at least two hydroxyl groups. The polyols may contain other functional groups, more especially amino groups, or may be modified with nitrogen. Typical examples are  
     [0126] glycerol;
