So far, known have the cleaning product and oily or the ointment preparation that are used to the property of water-bearing surfactant of taking a shower or having a bath that has more or less strong and significant cleaning function or return grease (Rueckfettung) effect.
The vesicle system is widely used at cosmetics and pharmaceutical field as active ingredient carriers and skin nursing component.This respect, the liposome that contains of known cosmetics is vesicle-containing colloid or emulsion, to contain liposome be the vesicle-containing dispersion and also prepared in the pharmacopedics field.Also introduce liposome base cleaning product.For example in " Mederma Regulativ-WaschlotionPlus ", relate to the emulsion-based cleaning product that contains liposome common on a kind of market.This preparation contains oil/water emulsifier and oils and fats mutually, does not contain the material of detergent active certainly.
Equally also introduced in water for bathing by oil bath preparation or factice body preparation and bathing tablet and formed liposome.DE-OS4205548 has described the bathing and the shower additive of (vesikelbildend) feature that has into vesicle, and it contains fatty oil and/or apolar substance, also contains one or more oil soluble surfactants and one or more become vesicle lipid.Here, the HLB value of oil soluble surfactant is 6-13, and becoming the HLB value of vesicle lipid is 2-6.
DE19602346.7 has introduced the factice body of the shower with vesicle feature, it contains more than 30% one or more lipophilic ingredients, 0.1-20% one-tenth vesicle material and common agent and additive have the emulsifier system of being made up of with 1: 2 to 1: 0.2 ratio one or more water/oil and one or more oil/water emulsifiers in addition.
This detergent that contains lipid, the loss of skin lipid in the time of can being equilibrated at decontamination, its preparation is to be undertaken by be manufactured into the one-tenth vesicle decentralized photo that makes in advance in preparation, or liposome, particularly under the situation as the bath additives use, form by the lipid that contains in the preparation by the water contact in use.
For the said goods, or do not contain surfactant or containing under the situation of surfactant, those particularly relevant systems with oil, they should stop the interaction of liposome structure and surfactant in the aqueous solution, so that it does not dissolve.Also do not exist at present the aqueous that does not contain fatty oil or oily ingredient and formation liposome structure to contain the preparation of surfactant.Always be to use into vesicle lipid in these cleaning products, producing liposome structure so far, for example phospholipid, sheath lipoid or ceramide.
R.A.Wachter etc. are in 75 years the 11/94th of Parf ü merie und Kosmetik (perfume and cosmetics), and the phytosterol of introducing the natural generation of use in the 755-759 page or leaf is as the active substance of plant in the cosmetics.Here, phytosterol can obtain from different oil and oils and fats, and for example Fructus Maydis oil, Oleum Brassicae campestris, Oleum Glycines, Fructus Canarii albi wet goods are made up of cupreol, campesterol and stigmasterol basically.ProductName Generol
122 be meant a kind of by the product mix above-mentioned three plant sterols components that obtain in the Oleum Glycines, that mainly form with cupreol (58.1%) and 29.8% campesterol and 4.5% stigmasterol.The ethoxylated products variant, particularly Generol that except that this this, also have above-mentioned plant sterol
122 variant.Obtain a series of products, for example Generol according to the ethoxyquin degree with different qualities
122 E5 (5Mol EO) mainly are hydrophobic, and those ethoxyquin degree are 10,16 or 25 product.
The product of back has the feature of typical oil/water emulsifier.In view of the above, the latter can and be used as solubilizing agent as the corresponding emulsifying agent of oil/aqueous emulsion, but not ethoxylated products is suitable for doing water/emulsifier or coemulsifier.Plant sterol also actively is used to be compromised or the skin by environmental effect, for example for body constitution neurodermatitis or dermatitis solaris symptom except the emulsifying feature.In addition, these products are done the emulsion except above-mentioned being suitable for, and also are suitable for the hairdo cleanout fluid.The shampoo that contains Generol by use can improve the gloss of wettable comb and hair.Introduce dry skin water/oily skin cream in the above-mentioned document, except that containing general water/emulsifier and different oil ingredients and thickening agent and stabilizing agent, also contained 1%Generol
122 make coemulsifier.In addition, a kind of hair flushing liquor has also been introduced in the there, and it also contains a kind of oil ingredient except containing cation emulsion substrate and thickening agent and additive, a kind of oil/water floating agent and 1.0%Generol
122.In addition, also determine Generol here
122 are fit to and long-chain fatty acid, aliphatic alcohol or phospholipid combination, formation multilamellar shape vesicle or layer.This is because phytosterol inserts in the laminar lipid layer.Ethoxylation Generol product and Generol
122 is to exist with layer structure on the contrary.Water content is lower than at 70% o'clock and produces lamellar phase, but water content brings up to and be higher than at 70% o'clock, and having taken place to multilamelar vesicles is the transition of liposome.Yet, do not allow to exist surfactant here.
But the Clean Living agent contains surfactant, and known its (referring to DE-PS4205548 and WO92/04010) has negative interaction to the stability of liposome because well-known liposome structure by with aqueous solution in surfactant interact and dissolve.To this, so far if do not have special stabilizing measures then can not form to have the liposome component and the general stable water-based system that contains surfactant concerning cleaning product.
Introduced among the US-A5688752 to wash and used and the nursing compositions, they are except containing surfactant, also contain by three component A, the lipid composite that B and C form with completely specified mol ratio, wherein A can be that ceramide, phospholipid, false vitalility are through amide, glycolipid or macrogol ester, B component is the hydro carbons of band polar end group, fatty acid for example, and component C is the helper component that is used for the stable final bilayer that constitutes.Component C for example has 3-β-sterol, or cholesterol, sitosterol, stigmasterol or ergosterol.Should be able to reduce the lipid loss of skin with these products, and therefore reduce dry.
Therefore, theme of the present invention is the aqueous-based cleaning system that preparation contains surfactant, it does not contain oily ingredient, but still has liposome structure when particularly using, and has reached thus to resemble the whole advantages that contain surfactant and contain known washing of lipid product or skin nursing aspect.
This task is achieved by preparation of aqueous-based cleaning according to the present invention, it contain 1-60% one or more particularly be selected from the surfactant of anion and/or nonionic and/or both sexes and/or cationic surfactant, in addition 0-5%, 0.5-2% one or more regulators particularly, 0-5%, 1-3% one or more stabilizing agents particularly, 0-3%, 0.1-1.5% one or more antiseptic particularly, 0-5%, 0.1-2% one or more thickening agents and 0-20% particularly, 0.5-3% active substance particularly, 0-1%, particularly 0.0005-0.01% dyestuff and 0-5%, particularly 0.5-2% one or more turbidity inducing agents or pearling agent, it is characterized in that containing 0.001-15%, particularly 0.01-15%, preferred more especially 0.5-10%, 0.5-5% one or more sterols particularly.
Show that astoundingly the preparation that contains surfactant for these aqueouss of specify forming by the spontaneous liposome structure that forms of one component, and still keeps this structure in preparation or use in washing process.This is visibly different with known oil-containing cleaning compositions, and they are to form liposome when using in water from the above mentioned.Wherein, the loss of the skin lipid that is taken place when the decontamination by surfactant can be remedied by the above-mentioned positive role of sterol.Except having outstanding cleaning function, also prevent the drying of skin thus.Surprisingly can abandon using line of oils to assign to reach this purpose.
