DE102012200383A1 - Adjusting the hardness of the peeling effect of the cosmetic cleaning cloths comprises impregnating the cloth with printed peeling-structure with a composition comprising e.g. aqueous-alcoholic solutions, hydrodispersions or oils - Google Patents

Abstract

Adjusting the hardness of the peeling effect of the cosmetic cleaning cloths by selecting the degree of impregnation comprises impregnation of the cloth with printed peeling-structure with a composition comprising an aqueous-alcoholic solutions, hydrodispersions, oil-in-water emulsions, water-in-oil emulsions or oil. An independent claim is included for the cleaning cloth imprinted with the peeling structure, whose peeling property is adjusted by the above method.

Description

The present invention relates to a method for adjusting the hardness of the peeling effect of cosmetic wipes by selecting the degree of soaking, characterized in that a cosmetic cleaning cloth with printed peeling structure with a cosmetic preparation selected from the aqueous-alcoholic solutions, hydrodispersions, O / W Emulsions, W / O emulsions or oils is soaked.

The production of cosmetic cleansing products has been increasing for years. This is mainly due to the increasing health awareness and hygiene needs of consumers.

Cleansing of the human body means the removal of (environmental) dirt and thus causes an increase in mental and physical well-being. Cleaning the surface of the skin and hair is a very complex process, depending on many parameters. On the one hand, substances coming from outside such as, for example, hydrocarbons or inorganic pigments from a wide variety of environments as well as residues of cosmetics or undesired microorganisms should be removed as completely as possible. On the other hand, bodily excretions such as sweat, sebum, dandruff and hair dandruff are to be washed away without profound interferences with the physiological balance of the skin.

A special product form for cleaning preparations are solid cleaning substrates or textiles, in particular cloths. These may already be impregnated with the cleaning preparation by the manufacturer (a combination for which the term "cleaning fleece" is also used in the context of the present invention) and thus have the advantage that the preparation is already predetermined in them in the correct dosage. In addition, they avoid the disadvantage of stored preparations in bottles, the packaging of which can break and "leak" their contents. Other advantages of cleaning wipes / fleeces include the fact that they can be comfortably taken in counted amount with travel and for their application usually no more water is required.

Cleaning wipes are made from textiles. Textiles may in principle be woven, knitted or knitted or present as a composite (English nonwoven textile). Most (for cost reasons) composites are used, as in the present invention. In composites fabric formation is not by warp and weft or knit, but by entanglement, and / or cohesive and / or adhesive bonding of textile fibers. Composites can after the DIN 61210 T2 in fleece, cotton wool and felt can be distinguished. Nonwovens are loose materials of staple fibers (ie, limited length fiber) or filaments (continuous fibers), usually made of polypropylene, polyester or viscose, the cohesion of which is generally due to the inherent adhesion of the fibers. In this case, the individual fibers may have a preferred direction (oriented or cross-layer webs) or non-directional (random webs). The nonwovens can be mechanically consolidated by needling, meshing or by swirling by means of sharp water jets. Adhesively bonded nonwovens are formed by bonding the fibers with liquid binders (eg acrylate polymers, SBR / NBR, polyvinyl esters, polyurethane dispersions) or by melting or dissolving so-called binder fibers which have been mixed into the nonwoven during production. In cohesive consolidation, the fiber surfaces are solubilized by suitable chemicals and bonded by pressure or welded at elevated temperature [ J. Falbe, M. Regnitz: Rompp-Chemie-Lexikon, 9th ed. Thieme-Verlag, Stuttgart (1992) ].

Substrates impregnated with cosmetic preparations (for example nonwovens) can be produced in different ways:
In the so-called "dip process" the cloth is immersed in a dip or pulled through a bath. This method is particularly suitable for paper towels and less for nonwovens, since the latter absorb too much liquid (= preparation) and then find puddles of re-released preparation in outer packaging.

A second variant is the "spraying process", in which the preparation is sprayed onto the passing cloth. These methods are suitable for all textiles, but no strong foaming preparations can be applied to the cloth, since the foam development in the spraying process is too large.

As a further method so-called stripping methods are used. There fleece or cloth webs run past scraper plates, bars or nozzles, which are continuously loaded with impregnation solution become. Different degrees of impregnation can be adjusted, inter alia, by varying the contact pressure and the fabric tension.

Cleaning wipes are usually offered in cosmetics in two different versions. On the one hand, the person skilled in the art knows wipes with a more or less smooth surface, which essentially achieve a cleaning effect by wiping off the skin surface. On the other hand, cloths with a rough surface are used, which exert an abrasive effect on the uppermost skin layers. These wipes are called due to the abrasive effect as peeling wipes (derived from the English to peel = peel off, peel).

A disadvantage of the state of the art of such exfoliating wipes is the fact that the hardness of the exfoliating effect (ie the noticeable, sensory hardness of the particles on the skin and their abrasive effect) is exerted by the exfoliation applied to the wipe or incorporated into the wipe. Particles, for example, silicon dioxides is determined. The once given hardness can not be varied. This results in the production of different hard peeling cloths that the manufacturer must hold several different cloth materials ready, which results due to economies of scale higher purchase prices and storage costs for the cloth materials. In addition, it comes in the production of different peeling towels by, in comparison to the change of impregnation preparation, time-consuming replacement of cloth rolls to delays in production in the process step of impregnation.

Last but not least, due to the limited selection of peeling materials suitable for cosmetics, only a limited number of degrees of hardness can be offered for exfoliation.

It was therefore the object of the present invention to eliminate the disadvantages of the prior art and to develop cleaning wipes or methods for adjusting the hardness of the peeling effect of cosmetic wipes, which allow a greater variety of degrees of hardness of the peeling effect and the manufacturing cost of the wipes to reduce.

Surprisingly, the object is achieved by a method for adjusting the hardness of the peeling effect of cosmetic wipes by selecting the degree of soaking, characterized in that a cosmetic cleaning cloth with printed peeling structure with a cosmetic preparation selected from the aqueous-alcoholic solutions, hydrodispersions, O / W emulsions, W / O emulsions or oils is soaked.

Surprisingly, the object is further achieved by a cosmetic cleaning cloth with printed peeling structure, in which the peeling properties is adjusted by the method according to the invention.
