Description

Die vorliegende Erfindung betrifft ein Reinigungsmittel, insbesondere ein Reinigungsmittel zur Reinigung der Haut.The present invention relates to a cleaning agent, in particular a cleaning agent for cleansing the skin.

Zur Entfernung von Verschmutzungen werden in vielen Bereichen lösungsmittelhaltige Reinigungsmittel eingesetzt. Solche sind insbesondere notwendig zurTo remove soiling, solvent-containing products are used in many areas Detergent used. Such are particularly necessary for

Entfernung von Farb- und Klebstoffrückständen und anderen Kunststoffmassen.Removal of paint and adhesive residues and other plastic materials.

Dabei werden in solchen Reinigungsmitteln beispielsweise Kohlenwasserstoffe, Ester, Ketone und Alkohole eingesetzt.In such cleaning agents, for example, hydrocarbons, Esters, ketones and alcohols used.

Häufig weisen Kohlenwasserstoffe und Alkohole nicht die erforderlichen Lösungseigenschaften für solche Substanzen auf.Frequently, hydrocarbons and alcohols do not have the required dissolution properties for such substances.

Substanzen mit guten Lösungseigenschaften wie beispielsweise Aceton, Methylethylketon, Ester wie N-Butylacetat oder Ethylacetat, besitzen zwar gute Löseeigenschaften sind jedoch gesundheitsschädlich und hautreizend.Substances with good dissolving properties, such as acetone, methyl ethyl ketone, Although esters such as N-butyl acetate or ethyl acetate, have good dissolving properties However, they are harmful and irritating to the skin.

Der Umgang mit solchen Stoffen sollte grundsätzlich geschultem Personal unter Einsatz der notwendigen Schutzkleidung vorbehalten bleiben.The handling of such substances should always be trained personnel Use of the necessary protective clothing reserved.

Aufgabe der vorliegenden Erfindung war es daher ein Reinigungsmittel bereit zu stellen, das gute Reinigungseigenschaften aufweist und dabei auf den Einsatz gesundheitsschädlicher oder reizende Substanzen zu verzichten.The object of the present invention was therefore a cleaning agent ready for which has good cleaning properties and thereby on the use to refrain from harmful or irritating substances.

Erfindungsgemäß wird die Aufgabe gelöst durch ein Reinigungsmittel enthaltend 20 bis 97 Gew.-% Methylal (Dimethoxymethan), 3 bis 50 Gew.-% Alkohol und 0 bis 50 Gew.-% Wasser. Ein solches Reinigungsmittel wird nicht als gesundheitsschädlich eingestuft.According to the invention the object is achieved by a cleaning agent containing 20 to 97% by weight of methylal (dimethoxymethane), 3 to 50% by weight of alcohol and 0 to 50% by weight of water. Such a cleaning agent is not considered harmful classified.

Das erfindungsgemäße Reinigungsmittel kann sowohl zur Reinigung von Oberflächen eingesetzt werden, die mit entsprechenden Substanzen verunreinigt sind als auch zur Reinigung beispielsweise verschmutzter Haut. The cleaning agent according to the invention can be used both for cleaning surfaces are used, which are contaminated with appropriate substances as well as for cleaning, for example, soiled skin.

Bevorzugt enthält das erfindungsgemäße Reinigungsmittel 30 Gew.-%, mehr bevorzugt mindestens 50 Gew.-% Methylal. Bevorzugte Bereiche liegen zwischen 30 und 85 bzw. 50 und 75 Gew.-% Methylal in dem Reinigungsmittel.The cleaning agent according to the invention preferably contains 30% by weight, more preferably at least 50% by weight of methylal. Preferred areas are between 30 and 85 and 50 and 75 wt .-% methylal in the detergent.

Besonders geeignete Alkohole sind einwertige aliphatische Alkohole wie Ethanol, Isopropanol und n-Propanol. Besonders bevorzugt ist hiervon Ethanol, da auch Ethanol nicht als reizend eingestuft ist. Bevorzugte Mengen sind mindestens 5 Gew.-%, mehr bevorzugt mindestens 10 Gew.-%.Particularly suitable alcohols are monohydric aliphatic alcohols, such as ethanol, Isopropanol and n-propanol. Of these, ethanol is particularly preferred, as well Ethanol is not classified as irritating. Preferred amounts are at least 5 Wt .-%, more preferably at least 10 wt .-%.

Das erfindungsgemäße Reinigungsmittel kann als Flüssigkeit, als Spray (eventuell mit einem Treibgas), als Gel, Paste, Creme, Feuchtreinigungspulver oder in Reinigungstüchern eingesetzt werden.The cleaning agent according to the invention can be used as a liquid, as a spray (possibly with a propellant), as a gel, paste, cream, wet cleaning powder or in cleaning wipes.

Insbesondere, wenn das Reinigungsmittel zur Hautreinigung eingesetzt werden soll, empfiehlt es sich den pH-Wert einzustellen auf einen Bereich von 3 bis 7. Hierfür sind insbesondere solche Säuren geeignet, die für kosmetische Anwendungen zugelassen sind, wie beispielsweise Milchsäure, Zitronensäure oder Weinsäure.In particular, when the cleaning agent is used for skin cleansing it is recommended to adjust the pH to a range of 3 to 7. For this purpose, especially those acids are suitable for cosmetic applications are permitted, such as lactic acid, citric acid or Tartaric acid.

Als Reinigungsmittel, insbesondere, wenn es sich um ein Hautreinigungsmittel handeln soll, können chemisch inerte kosmetische Rückfetter eingesetzt werden, beispielsweise Isopropylmyristat, Triglyceride, Weißöle, Glykole, Sorbitol, Glycerin, Naturöle, etc. Chemisch inert bedeutet, dass die Substanzen ihre rückfettenden Eigenschaften in dem Reinigungsmittel über einen üblichen Lagerzeitraum von zwölf Monaten nicht einbüßen.As a cleanser, especially if it is a skin cleanser chemically inert cosmetic moisturizers can be used, for example isopropyl myristate, triglycerides, white oils, glycols, sorbitol, glycerol, Natural oils, etc. Chemically inert means that the substances are their moisturizing Properties in the detergent over a common storage period of twelve months do not lose.

Darüber hinaus können übliche weitere Hilfsstoffe enthalten sein, wie Duftstoffe, Farbstoffe, Verdicker, Pigmente, Emulgatoren, Cellulose, Abrasiva, Stabilisatoren und Konsistenzgeber.In addition, conventional other auxiliaries may be included, such as fragrances, Dyes, thickeners, pigments, emulsifiers, cellulose, abrasives, stabilizers and bodying agent.

Das erfindungsgemäße Reinigungsmittel eignet sich insbesondere zur Hautreinigung. The cleaning agent according to the invention is particularly suitable for skin cleansing.

Mit dem erfindungsgemäßen Reinigungsmittel können insbesondere Polyurethanschäume, Polyurethandichtungsmassen, Silikondichtmassen, Farben, Lacke und/oder Fette von Oberflächen oder von der Haut entfernt werden.With the cleaning agent according to the invention, in particular polyurethane foams, Polyurethane sealants, silicone sealants, paints, Paints and / or greases are removed from surfaces or from the skin.

Gegenstand der Erfindung ist auch die Verwendung von Methylal zur Herstellung eines Reinigungsmittels, insbesondere zur Reinigung der Haut.The invention also provides the use of methylal for the production a cleaning agent, in particular for cleaning the skin.
