Definitions
- the present invention relates to a cleaning cloth impregnated with an impregnating agent based on an oil-in-water emulsion (O/W emulsion).
- O/W emulsion oil-in-water emulsion
- Cleaning wipes are a special form of cleaning agent because the cleaning performance is based on the interaction of the wipe and the impregnating agent.
- Cleaning wipes are characterized by the fact that it is a cleaning agent that is ready to use. No additional solvent, especially water, is required to develop the effect. Also, no solvent, especially water, is needed to wash away dirt. Cleaning wipes can be used conveniently on the go and when traveling or simply in between.
- cleaning cloths are used in a variety of ways, for example in leather and floor care, in the hygiene sector, in intimate and body care.
- cleansing wipes are also advantageously used for baby care, face and body cleansing, cleaning of the skin in the diaper area, and as toilet paper to promote toilet training in young children.
- facial cleansing When cleaning the face, dirt that has gotten onto the skin from the outside, dead cells and excess sebum must be removed. The dirt that has got onto the skin from the outside also includes make-up that has to be removed again.
- inorganic pigments such as silicates [magnesium silicate (talc), aluminum silicate (kaolin)] and metal oxides (chromium, iron, manganese, titanium and zinc oxides) organic color pigments are also used.
- silicates magnesium silicate (talc), aluminum silicate (kaolin)
- metal oxides chromium, iron, manganese, titanium and zinc oxides
- organic color pigments are also used.
- Stearic acid esters, lanolin alcohol and acetate are used as binding agents.
- Waxes such as beeswax or carnauba wax and oils such as paraffin oils, silicone oils or castor oil are used in many formulations.
- decorative cosmetics can contain preservatives, antioxidants, thickeners and other additives.
- Cleaning wipes have proven to be well suited for this purpose because the wiping motion of the wipes supports the cleaning effect of the surface-active substances and/or oils contained in the impregnating agent.
- DE 10157543 discloses emulsion-impregnated wipes, the emulsion containing chitosan and/or lecithin. This allows the content of emulsifiers and preservatives to be reduced.
- the document EP 1496853 describes cleaning wipes which are impregnated with an impregnating agent which contains starch-containing compounds.
- the incorporation of these starch-containing compounds leads to a particularly pleasant, smooth, velvety feeling on the skin.
- EP 1405632 discloses the incorporation of zinc oxide particles of a specific size into the impregnating agent and the possibility of applying this impregnating agent to the cloths.
- the document DE 102012200383 discloses cleaning cloths which have a rough surface. This leads to a peeling effect. In order to be able to control the strength of the peeling effect, different amounts of the impregnating agent are applied.
- Document DE 202004007851 describes colored cleaning cloths and impregnating agents. The dyes and impregnating agents used are selected in such a way that the color remains on the cloth and does not transfer into the impregnating agent.
- compositions containing lipids for impregnating wipes are described in document
- WO 2005/044220 A1 discloses.
- the effect of these impregnating agents is that cleaning articles impregnated with these agents have not only high cleaning power but also high refatting power.
- Classic cleaning cloths can therefore be impregnated with impregnating agents that dispense with the incorporation of “classic” surfactants, such as alkyl ether sulfates, which are generally used in liquid cleaning preparations. This can lead to reduced cleaning performance.
- Cleaning wipes containing oil are often used to remove waterproof make-up preparations. These cleaning cloths containing oil have the disadvantage that oils can get into the eye due to their varying degrees of spreading ability. This leads to reduced tolerability of these products.
- an oily residue often remains on the skin, which many users find unpleasant.
- the StdT also discloses cleaning wipes which have good cleaning performance and are well tolerated.
- the document DE 102015212822 A1 is mentioned as an example.
- the soaking agent has micelles.
- DE 102015212822 A1 is characterized in that it contains a mixture of different surfactants, anionic surfactants in the form of sodium acylglutamates, nonionic surfactants in the form of block polymers and alkyl polyglycosides.
- Cleansing wipes are intended to be used for cleaning, preferably for cleaning human skin and hair.
- dirt that has gotten onto the skin from the outside, dead cells and excess sebum must be removed.
- the dirt that has got onto the skin from the outside also includes make-up that has to be removed again.
- silicone compounds are a wish that is often expressed by consumers.
- microplastics are very important for consumers. However, there is no generally binding definition of what is meant by microplastics.
- the United Nations Environmental Program (UNEP) defines microplastics as solid, particulate materials below 5 nm in size that are not water-soluble, non-degradable and consist of plastic.
- UDP Environmental Program
- This group also includes, for example, representatives of polymers that are based on acrylate and also do not have good biodegradability.
- the ingredients of the saturant and the wipe material are as biodegradable as possible.
- cleaning wipes are to be provided which take account of the consumer's desire for increased compatibility and improved biodegradability, in particular with regard to the wipe material. Nevertheless, the cleaning performance should correspond to that of conventional cloths.

- Phenoxyethanol is particularly effective in acidic and neutral environments, but also in alkaline environments and is completely non-toxic. Adequate preservation of cosmetic products can already be achieved by using low concentrations. Because of its neutral taste, phenoxyethanol quickly found its way into the pharmaceutical and cosmetics industries. Its action is directed against Gram-positive and Gram-negative bacteria such as Escherichia coli, Pseudomonas aeruginosa, Proteus mirabilis, Staphylococcus aureus, and against yeasts such as Candida albicans and other microorganisms. Phenoxyethanol is a viscous liquid with a faint, slightly pleasant odor and an astringent taste. It has been found in nature in tropical fruits, in Cichorium endivia and in green tea (Camellia sinesis). It has a mild, rose-like flavor

- free from means that less than 0.001% by weight, preferably less than 0.0001% by weight, particularly preferably 0% by weight, of the respective substances, based on the total weight of the preparation, are present.
- the impregnating agent is in the form of an O/W emulsion.
- Emulsions are generally understood as meaning heterogeneous systems which consist of two liquids which are immiscible or only partially miscible with one another and which are usually referred to as phases.
- one of the two liquids is dispersed in the other liquid in the form of very fine droplets.
- the liquids pure or as solutions
- the two liquids are water and oil and oil droplets are finely distributed in the water, then it is an oil-in-water emulsion (O/W emulsion, e.g. milk).
- O/W emulsion oil-in-water emulsion
- the basic character of an O/W emulsion for example electrical conductivity, sensory properties, dyeability of the continuous phase, is shaped by the water.
- a water-in-oil emulsion (W/O emulsion, eg butter) is the reverse of the principle, with the basic character being determined by the oil.
- emulsions For their formation and for stabilization, emulsions generally require one or more emulsifiers, optionally also thickeners and/or consistency factors, in order to be stable over a cosmetically acceptable period of time.
- Emulsifiers ensure that two immiscible liquids (e.g. oil in water) can be mixed into an emulsion. Due to their amphiphilic character, they penetrate the oil with their fat-soluble part. The hydrophilic part allows the oil droplets formed by stirring or homogenization to be dispersed in the aqueous environment. Emulsifiers primarily have no washing-active, surface-active character.
- Emulsifiers reduce the interfacial tension between the two phases and, in addition to reducing the interfacial work, also stabilize the emulsion formed. They stabilize the emulsion formed by interfacial films and by forming steric or electrical barriers, which prevents the emulsified particles from flowing together (coalescence).
- a structural feature of such compounds is their amphiphilic molecular structure.
