Cleaning cloths impregnated with impregnation materials based on micellar technology

The present invention relates to cloths impregnated with impregnation materials which are characterized in that they are based on micellar technology.

The use of make-up for embellishing the external appearance, in particular of the face, is a phenomenon which has been observed for a long time. Already in ancient Egypt, eyeliner, eyeshadow, rouge and lipstick were used, by both men and women. In addition to a protective function, putting on make-up also had cosmetic effects. Make-up was applied simply for beauty purposes. This is also still the case today.

The make-up used also has to be removed. There is a special group of skin-cleaning products for removing make-up from the region of the face, specifically facial-cleaning products. As facial skin is particularly sensitive, products which are particularly gentle and which do not irritate the skin are used.

These days, there is a plurality of different substances which are used in the field of decorative cosmetics. Organic color pigments are used in addition to inorganic pigments such as silicates [magnesium silicate (talcum), aluminum silicate (kaolin)] and metal oxides (chromium, iron, manganese, titanium and zinc oxides). Inter alia, stearic acid ester, lanolin alcohol and lanolin acetate are used as binder. In many formulations, waxes such as beeswax or carnauba wax and oils such as paraffin oils, silicon oils or castor oil are used. Furthermore, decorative cosmetics can contain preservatives, antioxidants, thickeners and other additives.

To remove this large number of different substances from the skin completely, corresponding cosmetic cleaning agents are required. They must dissolve apolar compounds such as waxes, oils and silicon compounds and simultaneously absorb the difficultly-soluble pigments such as talcum or titanium oxide. This applies in particular to mascara, eyeshadow and eyeliner pencils. They must also be as hypoallergenic as possible in order not to trigger any reddening of the skin or irritation of the mucous membrane in users.

The cloths represent a specific embodiment of cosmetic cleaning agents. These can be impregnated with a cleaning preparation which supports the mechanical removal of dirt from the skin. Commercially available cloths impregnated with cleaning agents also have the advantage that they already contain the correct quantity of cleaning preparation. Additionally, cleaning cloths have the advantage that they are easily portable. This means that they are available at every opportunity for cleaning purposes, for example while travelling or also when working. Moreover, the cleaning cloths avoid the disadvantages of cleaning agents stored in bottles, where its packaging breaks and contents can leak.

The prior art contains many documents which disclose varied cleaning cloths with different impregnation materials.

DE 10157543 discloses emulsion-impregnated cloths, wherein the emulsion contains chitosan and/or lecithin. The content of emulsifiers and preservatives can be reduced as a result.

DE 10219638 discloses flat, perforated cleaning cloths which are impregnated with an emulsion-type impregnation material. These cloths bring about a gentle cleaning, in particular facial cleaning.

In document EP 1496853 cleaning cloths are described, which are impregnated with an impregnation material, which contains starch-containing compounds. The incorporation of these starch-containing compounds leads to a particularly pleasant, smooth, velvety skin sensation.

EP 1405632 discloses the incorporation of zinc oxide particles of a specific size in the impregnation materials and the possibility of applying these impregnation materials to the cloths.

In document DE 102012200383 cleaning cloths are disclosed which have a rough surface. This leads to a peeling effect. Different quantities of the impregnation material are applied to be able to control the strength of the peeling effect.

In document DE 202004007851, colored cleaning cloths and impregnation materials are described. The dyes and impregnation materials used are chosen such that the color remains on the cloth and does not overflow into the impregnation material.

Lipid-containing compositions for impregnating cloths are disclosed in document

WO 2005/044220 A1. These impregnation materials cause cleaning supplies impregnated with these agents to have a high fat-restoring capacity in addition to a high cleaning capacity.

Classic cleaning cloths are thus frequently impregnated with impregnation materials which are based on surfactant-free preparations. This can lead to the cleaning performance being reduced. In particular, the removal of waterproof make-up, and here in particular waterproof mascara, is problematic with such impregnated cleaning cloths. Oil-containing cleaning cloths are therefore frequently used to remove waterproof make-up preparations. These oilcontaining cleaning cloths have the disadvantage that oils can enter the eye on the basis of their varied high spreading capacity. The thinner an oil is, the greater, generally, the spreadability and therefore the easier it can enter the eye. However, other raw materials contained in the preparation can also enter the eye with the oils. This leads to a reduce compatibility of these products. Furthermore, when using oil-containing cleaning cloths, often a greasy residue remains on the skin which many users perceive as unpleasant.

Aqueously impregnated cloths require adequate preservation to prevent pathogens from being introduced into the eye area. In addition to other organs, the eye is also characterized by a reduced activatability of the specific and non-specific immune system. This is called immune privilege. Likewise, when selecting the preservatives care should be taken that these substances have the smallest possible irritant potential for the eye area.

Therefore, it was the object of the invention to overcome the defects of the prior art and to develop cloths impregnated with aqueous cleaning agents, the cleaning strength of which is improved such that waterproof make-up preparations, and in particular waterproof mascara preparations, can be removed without problems. The products are intended to be adequately preserved, and very compatible.

Surprisingly, the named objects are achieved by cloths impregnated with an aqueous impregnation material which contains block polymers and a mixture of selected surfactants.

The mixture according to the invention of selected surfactants contains on the one hand at least one sodium acyl glutamate. Preferably, the following sodium acyl glutamates are used:

sodium/disodium cocoyl glutamates, sodium/disodium lauroyl glutamates as well as sodium/disodium myristoyl glutamates. It is quite particularly preferred if disodium cocoyl glutamate is used as sodium acyl glutamate. Disodium cocoyl glutamate can for example be obtained under the trade name Protelan AGL 95/C from Zschimmer & Schwarz.

The impregnation materials according to the invention contain sodium acyl glutamates in a content of from 0.001 to 1 wt.%, preferably of from 0.003 to 0.75 wt.%, particularly preferably of from 0.005 to 0.5 wt.%, relative to the total weight of the impregnation material.

The mixture according to the invention of selected surfactants contains on the other hand at least one alkyl polyglycoside. Preferably the following alkyl polyglycosides are used: decyl glucosides, lauroyl glucosides and cocoyl glucosides. It is quite particularly preferred if decyl polyglucose is used as alkyl polyglycoside. Decyl polyglucose can for example be obtained under the trade name Plantacare 2000 UP from BASF Personal Care.

The impregnation materials according to the invention contain alkyl polyglycosides in a content of from 0.01 to 1 wt.%, preferably of from 0.025 to 0.8 wt.%, particularly preferably of from 0.05 to 0.6 wt.%, relative to the total weight of the impregnation material.

In the impregnation materials according to the invention, the weight ratio of the sodium acyl glutamates to the alkyl polyglycosides is 30:1 to 0.001:1, preferably 20:1 to 0.05:1.

The impregnation materials according to the invention contain at least one block polymer. Block polymers are copolymers of ethylene oxide and propylene oxide units called poloxamers. They are described by the formula

HO(C₂H₄O)_a(C₃H₆O)_b(C₂H₄O)_aH, wherein b can adopt values from 15 to 67 and a the values 1 to 130. The proportion of “a” units can account for 20 to 90% of the poloxamer. The following poloxamers are preferably used: poloxamer 101, poloxamer 124 and poloxamer 184. The use of poloxamer 124 is particularly preferred. This compound can for example be obtained under the trade name Synperonic PE/L44 from Croda (ICI Chemicals & Polymers).

The block polymers are present in a content of from 0.1 to 8 wt.%, preferably of from 0.2 to wt.%, particularly preferably of from 0.25 to 4 wt.%, relative to the total weight of the impregnation material, in the impregnation materials according to the invention.

In the impregnation materials according to the invention, the weight ratio of the at least one block polymer to the mixture of the at least one sodium acyl glutamate and the at least one alkyl polyglycoside is 3.63:1 to 0.28:1.

The mixture according to the invention of surfactants with block polymers in impregnation media for cleaning cloths has led to the possibility of achieving a stable preservation with good compatibility. The mixture according to the invention was brought into contact with the pathogen A. brasiliensis. Already after 24 h only very few pathogens could be seen. The pathogen A. brasiliensis, which is frequently seen in contaminations of cleaning cloths, is well controlled by the mild but effective preservation of the preparation according to the invention. After 24 h, more than 99.8 % of the A. brasiliensis pathogens are killed off in the preparation according to the invention. The results are shown in Figure 1.

Preservatives are those preserving substances which, according to the cosmetics regulation for Germany and according to Regulation (EC) No. 1223/2009 concerning cosmetic agents, are approved for use in cosmetic products for Europe.

Preferably phenoxyethanol, methyl, ethyl, propylparaben, polyaminopropyl biguanide, potassium sorbate, benzethonium chloride, sodium benzoate, sodium salicylate and benzyl alcohol can be used as preservatives.

Stabilizers within the scope of the present invention are understood to be those substances which are not mentioned in the list of approved preservatives (cosmetic regulation, Annex 6; Regulation (EC) no. 1223/2009, codicil V), but nevertheless have a stabilizing effect and/support the stability of the preparation for 36 months in joint use with preservatives.

The following compounds are advantageous as stabilizers: Alcohol denat., propylene glycol, ethylhexylglycerin, 1,2-hexanediol, trisodium EDTA, methylpropanediol, butylene glycol, caprylyl glycol, piroctone olamine and pentylene glycol.

Preferably, the compounds phenoxyethanol, methyl, ethyl, propylparaben, alcohol denat., ethylhexylglycerin, 1,2-hexanediol, polyaminopropyl biguanide, trisodium EDTA, caprylyl glycol and piroctone olamine and quite particularly preferably the compounds phenoxyethanol, alcohol denat., ethylhexylglycerin, 1,2-hexanediol and trisodium EDTA are used in the impregnation materials according to the invention.

The preservatives and/or stabilizers are present in a content of from 0.0001 to 10 wt.%, preferably of from 0.0005 to 8 wt.%, particularly preferably of from 0.001 to 7 wt.% in the impregnation materials.

Surprisingly, it has been found that alcohol denat. can be used not only as stabilizer but also the moistening of the cloths is positively influenced. A further advantage is that the cloths are very moist at a low degree of impregnation and appear to be moist for longer.

Surfactants are amphiphilic substances which can dissolve organic, apolar substances in water. They are characterized by an ambivalent behavior to water and lipids. The surfactant molecule contains at least one hydrophilic and one lipophilic group which make possible the accumulation at the boundary surface between these two substance classes. In this way, surfactants ensure a reduction in surface tension of the water, wetting of the skin, the facilitation of removal and dissolution of dirt, easy rinsing and - as desired - also for foam regulation. This provides the basis for removing dirt from lipid-containing impurities.

In the present invention, the surfactants or amphiphilic molecules, more specifically a combination of block polymers and a mixture of sodium acyl glutamates and alkylpolyglycosides, are used in such a quantity that micelles form spontaneously. These micelles are aggregates which congregate spontaneously from amphiphilic molecules in a dispersion medium. The intention can be developed that the lipophilic portion of the micelles accumulates on the apolar substance, for example residues of make-up and other impurities, and these are then rinsed off or removed with a cleaning cloth by means of the hydrophilic portion of the structure.

The combination of at least one block polymer and a mixture of at least one sodium acyl glutamate and at least one alkyl polyglycoside, in particular the combination of disodium cocoyl glutamate, decyl polyglucose and poloxamer 124, is present in a content of from 0.15 to 10 wt.%, preferably 0.36 to 7 wt.%, relative to the total weight of the impregnation material.

The formation of micelles in the impregnation medium has been demonstrated; see on this point Figure 2. By way of example, a combination of disodium cocoyl glutamate, decyl polyglucose and poloxamer 124, realized in the selected example formulation 4 with the apparatus Horiba LB 550, was analyzed for dynamic light scattering. The sample was measured as an aqueous, undiluted sample. Measurement took place using the following parameters:

- Duration of measurement: 120 s

- Number of iterations: n = 3000

- Type of distribution: Number

- Measurement temperature: 23.3°C range: 23.3-23.4°C),

- Sensor: Liquid sensor,

- Scattered-light intensity (static): 1.53,

- Scattered-light intensity (dynamic): 3.06.

The diameter of the micelles was given in [nm] on the x axis, while on the y axis (left), the proportion of individual curves is applied with q, while the sum of the individual curves is given on the right-hand side. Each individual curve represents a measurement; the plurality of the curves illustrates multiple measurements. The formation of micelles could be shown. The formed micelles were shown in the range of from 5 to 55nm.

The presence of the described micelles makes it possible to remove apolar impurities, in particular waterproof make-up residues such as waterproof mascara, using aqueous impregnation materials. The principle is part of the nature of this matter. Micelles are structured such that the polar portion points outwards as the “head group” and can thus be supported as micelle in the polar impregnation medium. The apolar portion of the micelles is internal, with the result that the dirt is embedded directly in the center, and thus can be decreased using the polar portion with the impregnation medium.

A study with subjects showed that the micellization is advantageous for the product properties of a selected product according to the present invention. The investigation was carried out on 30 women aged from 19 to 64 who said they had sensitive skin. The test subjects were not allowed to use any oil-heavy skincare and cleaning products for seven days before the start of the measurements; likewise, they had to avoid exposure to strong sunlight and solarium visits. The test product was applied to the facial skin, twice daily for seven days, in a normal quantity. The test product is indicated as number 4 in the example formulations. The study participants received a questionnaire which had to be handed in and evaluated at the end of the study. The questions related to different product properties and product performances. Thus, i.a. the cleaning performance of the test product was requested. 91% of the test subjects indicated that the test product cleans thoroughly and 82% judged that the test product removes make-up residues effectively. It was thus possible to show that impregnation materials according to the invention bring about the removal of make-up.

The use of natural, vegetable oils in the impregnation materials is also preferred. These oils consist substantially of mixed triacylglycerols of higher fatty acids with an even number of carbon atoms. In addition, small quantities of acyl lipids (e.g. sterol ester) also and contain a portion of unsaponifiable components. Vegetable oils have almost exclusively evennumbered fatty acids and are liquid substances at 20°C. The fatty acids can be substituted, for example with one or more hydroxyl groups. Examples of vegetable oils which can be used according to the invention are almond oil, grape seed oil, macadamia oil, argan oil, jojoba oil, avocado oil, borage oil, stinging nettle oil, thistle oil, peanut oil, hempseed oil, coconut oil, pumpkin seed oil, linseed oil, corn oil, poppy-seed oil, evening primrose oil, olive oil, sesame oil, soya oil, sunflower seed oil, walnut oil, wheat germ oil and mixtures thereof. Almond oil, grape seed oil, argan oil, olive oil, macadamia oil and mixtures thereof are particularly preferred.

Embodiments of impregnation materials which contain at least one natural, vegetable oil have a content of natural, vegetable oils in the impregnation materials of from 0.1 to 2 wt.%, preferably of from 0.2 to 1 wt.%, relative to the total weight of the impregnation material. Overall, the incorporation at least of one natural, vegetable oil in the impregnation materials according to the invention leads to an improved care performance and simultaneously to a reinforcement of the cleaning performance.

The use of sorbitol in the impregnation materials is furthermore advantageous. Sorbitol is a sugar alcohol and is used in cosmetic preparations often as a humectant. Originally, sorbitol was obtained from specific crops such as for example from the crops of mountain ash and stone fruit. Sorbitol is present in the impregnation materials in a content of from 0.1 to 5 wt. %, preferably of from 0.25 to 4 wt.%, particularly preferably of from 0.35 to 3 wt.%, relative to the total weight of the impregnation material. Proceeding from the function of the sorbitol as humectant, the humidification performance of the impregnated cleaning cloth can overall be improved by using sorbitol.

The effect of sorbitol was not examined; the results are represented in Figures 3a and 3b. The investigations were carried out on 30 women aged from 18 to 65 who said they had sensitive skin. The test subjects were not allowed to use any oil-heavy skincare and cleaning products for seven days before the start of the measurements; likewise, they had to avoid exposure to strong sunlight and solarium visits. The first measurement for determining the skin moisture with the Corneometer® CM 825 from Courage + Khazaka (Cologne, Germany) took place after an acclimatization of 30 minutes at a temperature of 21±1°C and

50±5% relative humidity, under standard atmospheric conditions. Three marked areas on the forearm were measured. The base valued for skin moisture were determined from the measurement values. These values correspond to the values at to. Subsequently, a reference product was applied to the three skin areas, and water was applied to the test subject as control. The use of the respective samples took place twice daily for 14 days. Thereafter, a renewed Corneometer measurement of the treated skin areas of the forearm took place under identical measurement conditions. The obtained measurement values correspond to the measurement values at t2. The difference of t2—to was formed for evaluation. The average values of the differences from the base values to were established and represented in the table and in the diagram. In Figure 3, ti stands for measurement times different from tO. Where 'a.u.' is mentioned, this means arbitrary units. The Figures show that the product according to the invention brings about a significant increase in skin moisture (li). On the contrary, the reference product leads to a significant reduction of the values for skin moisture (ft). Example formulation no. 4 served as test product. An internal standard served as reference product. The test product is a selected impregnation material for the cloths according to the present invention.

An internal standard product which, in addition to the surfactants contains disodium cocoyl glutamate and decyl glucoside, poloxamer 124, glycerol, sorbitol, propylene glycol, 1,2hexanediol, trisodium EDTA, phenoxyethanol and further components in small quantities, served as reference product.

Furthermore, the use of 1,2-hexanediol in the impregnation materials according to the invention is possible, without it leading to odor problems. Normally, the use of 1,2-hexanediol in cosmetic products leads to odor problems as 1,2-hexanediol has an inherent odor and is perceived per se as having an unpleasant smell. 1,2-hexanediol is used to support moisture performance, to keep the impregnated cloth moist and simultaneously to influence the microbial stability of the cloths positively. The content of 1,2-hexanediol in the impregnation materials is 0.1 to 1 wt.%, preferably 0.25 to 0.5 wt.%, relative to the total weight of the impregnation material.

According to the invention, the impregnation materials can contain cosmetic auxiliaries as are used normally in such preparations, e.g. emulsifiers, complexers, perfumes and dyes.

Further auxiliaries according to the invention are further moistening and/or moisture-retaining substances, further fats, oils or other normal components of a cosmetic formulation such as alcohols, polyols, polymers, foam stabilizers, electrolytes, organic solvents or silicon derivatives.

The test subjects involved in the study for measuring skin moisture also assessed the test product regarding product properties and product performances. A questionnaire was handed out which was collected and evaluated at the end of the study. It has been shown that the test product does not cause any reddening, tightness and no dryness of the skin. 79% of those questioned came to this judgement. 76% of the study participants questioned judged that the signs of sensitive skin are reduced by the test product. These statements demonstrate that the test product is a selected product according to the present invention, does not cause much irritation and is compatible.

Cosmetic or dermatological cloths can consist both of water-soluble materials (e.g. such as toilet paper) and also water-insoluble materials. Furthermore, the cloths can be smooth or also surface-structured. Surface-structured cloths are preferred according to the invention.

“Dry” cloths which consist of non-woven fabric, in particular hydroentangled and/or hydroembossed non-woven fabric, are preferred according to the invention in combination with the impregnation materials according to the invention.

Such non-woven fabrics can have macroembossments of each desired pattern. The appropriate selection is directed to the impregnation to be applied, depending on the field of application on which the later cloth is intended to be used.

If embossed non-woven fabrics are used, then large cavities on the surface of the non-woven fabric and also therein simplify the absorption of dirt and impurities if the cloth is moved over the skin. The cleaning effect can be increased compared with non-impregnated cloths many times over.

It has been shown to be advantageous for the cloth if this has a weight of from 30 to 120 g/m², preferably of from 35 to 60 g/m² (measured at 20 C±2°C and at a moisture of room air of 65% ± 5% for 24 hours).

The thickness of the non-woven fabric is preferably of from 0.4 mm to 2 mm, in particular of from 0.45 mm to 0.7 mm.

Generally, all organic and inorganic, natural and synthetic fibrous materials can be used as starting materials for the non-woven fleece of the cloth. By way of example, viscous, cotton, cellulose, jute, hemp, sisal, silk, wool, polypropylene, polyester, polyethylene terephthalate (PET), aramid, nylon, polyvinyl derivatives, polyurethanes, polylactide, polyhydroxyalkanoate, cellulose ester and/or polyethylene and also mineral fibers such as glass fibers or carbon fibers are listed. However, the present invention is not limited to the named materials, but a plurality of other fibers can be used to form the non-woven fabric. It is particularly advantageous within the scope of the present invention, if the fibers used are non-water-soluble.

In a particularly advantageous embodiment of the non-woven fabric, the fibers consist of a mixture of 70% PET and 30% tensel/lyocell. Lyocell is a regenerated fiber consisting of cellulose, and industrially produced, and has a high dry and wet strength. Such cloths can for example be obtained from Spuntech under the name 1T3P45P70L300B.

In a further particularly advantageous embodiment, the fibers consist 100% of viscous. Such cloths can for example be obtained from Spuntech under the name 13P46V100.

Fibers of high-strength polymers such as polyamide, polyester and/or highly-drawn polyethylene are particularly advantageous.

Additionally, the fibers can also be dyed to be able to accentuate and/or increase the visual attractiveness of the non-woven fabric. The fibers can also contain UV stabilizers and/or preservatives.

The fibers used to form the cloth have preferably a water absorption rate of more than 4 mm/[10 sec] (measured according to ERT 10.4-02, WSP 10.1), in particular more than 6 mm/[10 sec].

Advantageous cloths within the scope of the present invention have a tensile strength of in

particular	[N/50 mm]

According to the invention, the weight ratio of the non-impregnated cloth to the impregnation material is advantageously 1:1 to 1:5.

The subject matter of the present invention is likewise the use of cloths according to the invention for cleaning skin, in particular facial skin.

Another subject matter of the present invention is the use of cloths according to the invention for removing decorative cosmetics, in particular waterproof make-up, even more particularly waterproof mascara.
