Description

DRY COSMETIC TOWELS WITH STRUCTURED SURFACE

Field of the Invention

The invention is in the field of cosmetics and relates to facial tissues with a special structure, which contain defined care and cleaning substances with particulate wax bodies, are moistened before use and are distinguished by good sensory properties combined with good foam and cleaning properties.

State of the art

Facial tissues are a form of application that is becoming increasingly important in the field of personal care. These are usually wet wipes that represent textile fabrics, nonwovens or even tissue papers that are soaked in a cleaning or care formulation.

Numerous patent applications describe cleaning wipes in which solutions are drawn onto different fabrics. Starting with the cleaning function aimed at in the first market-ready cosmetic tissues, care is increasingly the focus today. For example, in international patent application WO 95/35411 wet wipes are proposed which are impregnated with a lotion which, in addition to mineral oil, fatty acid esters, fatty alcohol ethoxylates and fatty alcohols. For some time now, cloths have also been offered which are in dry form and must be moistened before use, as described in the patent applications WO 99/13861 and WO 01/08657.

As a rule, structureless, non-woven fabrics are impregnated and / or coated with formulations containing surfactants and care agents and then dried. Depending on the size of the wearer, this can be impregnated disposable washcloths or smaller cleaning pads.

Hygiene and easy handling of these agents meet today's demands in terms of user friendliness, effectiveness and time saving. However, the requirements for the cleaning effect, the skin feel during and after use and the ease of use pose a technical challenge to the The amount of foam, stability and foam structure generated after moistening has a significant influence on the sensory sensation during and after cleaning. The suitable foam structure and sufficient foam volume after moistening are difficult to achieve with your hands without strong mechanical processing of the cloth. This problem can be made increasingly difficult by other nourishing non-surfactant additives.

It is therefore an object of the present invention to provide dry cosmetic wipes with improved cleaning, nourishing and sensory properties for the care and cleaning of the body and hair, which enable technically simple and inexpensive production.

It is particularly desirable to have a pleasant feeling on the skin during and after use, which should be supported by the optimized foam properties of the agent.

Description of the invention

The invention relates to dry facial tissues, characterized in that they have a uniform, structured surface with punctiform to oval depressions and are impregnated with a solution containing

(a) anionic and / or cationic and / or nonionic and / or amphoteric and / or zwitterionic surfactants and

(b) wax dispersions with particles with average particle sizes from 0.08 to

13 μm. It has been found that a synergism between the components of the formulation and the structure of the facial tissues enables foam formation which is advantageous for the cleaning effect and the feeling on the skin to be achieved after only a brief mechanical influence after moistening.

Through the combination of surfactant formulations containing nourishing, finely dispersed particulate wax dispersions of a defined particle size and / or liquid-crystalline waxes with cloths with a structured surface with small depressions, a fine-pored, voluminous foam can be generated quickly with little mechanical influence. The size of the wax particles and the structured tissue surface on the one hand have an influence on the foam properties, on the other hand wax bodies and cleaning components leave a pleasant feeling on the skin during and after cleaning. The formulation, containing the aqueous surfactant system and the finely dispersed wax body, enables impregnation or coating of the carrier materials in one manufacturing process. carrier

The special carrier systems to which the present invention relates can be constructed in one or more layers. In addition to paper-based tissues, appropriate tissue fabrics made of fiber or fleece are also suitable. Examples of natural fibers include silk, cellulose, keratin, wool, cotton, jute, linen, flak, for synthetic fibers acetate, acrylate, cellulose ester, polyamide, polyester, polyolefin, polyvinyl alcohol, polyurethane fibers , or polyolefin fabrics hydrophilized by additives and mixtures of these fibers or fabrics. Reaction products of 1 part of polyethylene glycol with 2 parts of fatty acids with 10 to 12 carbon atoms or their derivatives are used for the hydrophilization of the polyolefin-containing fabrics.

Non-woven fabrics are preferred, since these can be better provided with the desired structure according to the invention; supports made of viscose-polyester mixtures are particularly suitable for this. However, carrier systems of 50 to 90% by weight of viscose and 50 to 10% by weight of polyester which are crosslinked by the action of water are preferred, carriers of 60 to 80% by weight of viscose and 40 to 20% by weight of polyester are particularly preferred; up to 70% by weight viscose and 35 to 30% by weight polyester.

The size of the cloths is generally between 100 and 500 mm in length and between 100 and 500 mm in width, with length and width dimensions between 120 and 220 mm being preferred. However, the fabric can also be in the form of a glove and may then have multiple layers, so that the inner fabric layer of the glove turns out to be more hydrophobic, has a barrier function and offers protection against the hand coming into contact with the formulation or with moisture.

The carrier substances of the cosmetic tissues according to the invention have a uniform, structured surface with punctiform to oval depressions due to their production - the action of water with a so-called hydroentanglement belt. These depressions - also called dimples - have a round to oval shape with 0.1 to 1 mm, preferably 0.2 to 0.6 mm in diameter respectively. Width and 0.5 to 5.0 mm, preferably 0.8 to 1.5 mm in diameter respectively. Length. They can be on both sides or only from one side. In the case of one-sided depressions, they take up between 50 and 99%, preferably between 60 and 85%, of the thickness of the support; in the case of depressions on both sides, this proportion must be divided accordingly. An average of between 500 and 4000, preferably between 1500 and 3500, and particularly preferably between 2500 and 3200 of such dimples are present per 100 mm ^{2 support} surface.

In combination with the components of the formulation, the recesses contribute to the advantageous foam development. They hold small air bubbles which, when the Cloth which accelerate and improve the foam formation caused by the formulation and mechanical processing - mainly by rubbing between the hands. In this way, they contribute to an advantageous fine-pored foam structure with a large foam volume.

Furthermore, the weight of the carrier has an influence on the foam quality and quantity. As a rule, the fabrics have a weight per square meter of 10 to 150 g, preferably 20 to 120 g, particularly preferably 40 to 100 g and especially 70 to 90 g and a thickness of 0.1 to 1.5 mm, preferably 0.2 to 1.0 mm, particularly preferably 0.4 to 0.8 mm and especially 0.6 to 0.7 mm.

The properties of the carrier must be coordinated with the components of the applied formulation in order to achieve the synergistic effect with regard to cleaning and sensory properties.

Particle sizes of the wax dispersions and particle size determination

The particle sizes of the wax dispersions that are used in the impregnation and coating solutions have a significant influence on the sensory properties and foam and cleaning properties of the wipes. You need for the optimal setting Average particle sizes in the dispersions are from 0.08 to 13 μm, preferably 0.1 to 10 μm, particularly preferably 0.5 to 4 μm and especially 1 to 2 μm. For this purpose, the conventional methods for dispersion production known to the person skilled in the art are selected. For example, the particle sizes can be set by varying the loading of the dispersions in high-pressure homogenizers.

The respective conditions for setting the average particle sizes must, however, be adapted depending on the wax bodies selected and other auxiliaries of the wax dispersions. Since the particle reduction usually goes hand in hand with an increase in the temperature of the medium and the further processing of the wax dispersions should be possible without changing the particle sizes, wax bodies should be selected that have a melting point or. Have melting range from 50 to 85 ° C, preferably from 55 to 70 ° C.

The particle sizes were determined using the Coulter LS 230 laser particle analyzer from Beckman Coulter. In addition to classic laser diffraction, the device also uses the PIDS (polarized intensity differential scattering) method to expand the measuring range to the submicron range. The laser generates light with a wavelength of 750 nm, which is supplemented by the PIDS technology with the wavelengths 450, 600 and 900 nm. The 132 detectors have a total measuring range of 0.04 - 2000 μm, which is divided into 116 size classes. The software evaluates either according to the Frauhofhof see diffraction theory or according to the scattered light theory according to Mie.

The measured samples were diluted by a factor of 100 by the sample feed module, with demineralized water serving as the dispersing medium. The sample feed module ensures constant circulation of the dispersed sample through the measuring cell. Before the actual measurement started, the circulating sample was subjected to an ultrasound treatment of 30 s. This was done using an ultrasound module from Beckman Coulter connected to the measuring device. The evaluation was carried out exclusively according to the scattered light theory according to Mie using a refractive index of 1.47 for the dispersed medium. The average particle size data given relate to the D ₅₀ value of the volume distribution.

production method

The surfactant formulations with nourishing, finely dispersed particulate wax dispersions of a defined particle size are applied to the structured fabric in such a way that the dispersion, after the subsequent drying process by warm air drying, vacuum drying or drum drying, is loosely applied to the carrier as a discontinuous layer liable. The temperature during the drying process should be chosen so that the dispersion does not adhere too strongly to the structured fabric. This also presupposes that the depressions in the tissue and the particle sizes of the wax body particles are coordinated with one another. The dimples in the tissue may only be smaller or significantly larger than the dispersed and subsequently applied wax body particles, since otherwise a simple dispersion of the particles during foam formation is not guaranteed.

The residual water content after drying or water content of the dry facial tissues according to the invention is between 0.1 and 4% by weight, preferably 0.5 to 3% by weight and particularly preferably between 0.8 and 2% by weight of water, based on the Weight of the dry, non-impregnated carrier.

Deodorants and germ inhibitors

Cosmetic deodorants counteract, mask or eliminate body odors. Body odors arise from the action of skin bacteria on apocrine sweat, whereby unpleasant smelling breakdown products are formed. Accordingly, deodorants contain active ingredients which act as germ-inhibiting agents, enzyme inhibitors, odor absorbers or odor maskers.

> Germ inhibitors

In principle, all substances effective against gram-positive bacteria are suitable as germ-inhibiting agents, such as.

odor absorbers

Suitable odor absorbers are substances that absorb odor-forming compounds and can retain them to a large extent. They lower the partial pressure of the individual components and thus also reduce their speed of propagation. It is important that perfumes must remain unaffected. Odor absorbers are not effective against bacteria. They contain, for example, a complex zinc salt of ricinoleic acid or special, largely odorless fragrances, which are known to the person skilled in the art as "fixators", such as, for example, the main component. B. extracts of Labdanum or Styrax or certain abietic acid derivatives. Fragrance agents or perfume oils act as odor maskers and, in addition to their function as odor maskers, give the deodorants their respective fragrance. Perfume oils are, for example, mixtures of natural and synthetic fragrances. Natural fragrances are extracts of flowers, stems and leaves, fruits, fruit peels, roots, woods, herbs and grasses, needles and branches as well as resins and balms. Animal raw materials, such as civet and castoreum, are also suitable. Typical synthetic fragrance compounds are products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type. Fragrance compounds of the ester type are, for example, benzyl acetate, p-tert-butylcyclohexyl acetate, linalyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, allyl cyclohexyl propionate, styrallyl propionate and benzyl salicylate.

Fragrance compounds of the ester type are e.g. Benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinylacetate, phenylethyl acetate, linylbenzoate, benzyl formate, ethylmethylphenylglycinate, allylcyclohexylpropionate, styrallylpropionate and The ethers include, for example, benzyl ethyl ether, the aldehydes e.g. the linear alkanals with 8 to 18 carbon atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamenaldehyde, hydroxycitronellal, lilial and bourgeonal, to the ketones e.g. the Jonone, α-Isomethylionon and Methylcedrylketon, to the alcohols Anethol, Citronellol, Eugenol, Isoeugenol, Geraniol, Linalool, Phenylethylalkohol and Terpineol, to the hydrocarbons belong mainly the Terpenes and Balsame. However, preference is given to using mixtures of different fragrances which together produce an appealing fragrance. Essential oils of lower volatility, which are mostly used as aroma components, are also suitable as perfume oils, e.g. Sage oil, chamomile oil, clove oil, lemon balm oil, mint oil, cinnamon leaf oil, linden blossom oil, juniper berry oil, vetiver oil, oliban oil, galbanum oil, labolanum oil and lavandin oil.

Suitable flavors are, for example, peppermint oil, spearmint oil, anise oil, star anise oil, cumin oil, eucalyptus oil, fennel oil, lemon oil, winter green oil, clove oil, menthol and the like. dyes

The dyes which can be used are those substances which are suitable and approved for cosmetic purposes, as compiled, for example, in the publication "Cosmetic Dyes" by the Dye Commission of the German Research Foundation, Verlag Chemie, Weinheim, 1984, pp. 81-106. Examples are culinary red A (CI 16255), patent blue V (CI42051), indigo (CI73015), chlorophyllin (CI75810), quinoline yellow (CI47005), titanium dioxide (CI77891), indanthrene blue RS (CI 69800) and madder varnish (CI58000). Luminol may also be present as the luminescent dye. These dyes are usually used in concentrations of 0.001 to 0.1% by weight, based on the mixture as a whole.

application test

Different impregnation dispersions (amounts in% by weight of active substance, Tables 3, 4) were prepared by simply mixing the components; 67% viscose / 33% polyester fabric of 80 g / m ² in a size of 18.8 cm by 14.8 cm was then produced in accordance with the specification (Table 1) with 1-3.0 g of the dispersions (Table 3 , 4) moistened and at max. Dried in the oven at 50 ° C for 2 hours.

In a panel test with 4 people, the dry facial tissues were moistened with an excess of water under the tap, rubbed between the hands for 20 seconds and used to clean the palm of the hand.

The sensory feeling of the dry and moistened cloth in the hands, the skin feeling during use (moist), the skin feeling after application and drying of the back of the hand (dry), the time for foam production, the structure of the foam and the foam volume were assessed. [Assessment: 1 = bad, 2 = moderate, 3 = good]
