SUSTAINABLE CLEANING AND PRESERVATIVE

[1] Sustainable cleaning and preservative for the elimination of

Surface contamination and surface inclusions with following

Sealing of the surfaces.

Description:

[2] The present invention is in the field of emulsions of natural waxes in water and alcohol and their use in sustainable / natural cleansing, preserving and conditioning products.

[3] Waxes are generally used in the form of emulsions in water, as they are more easily miscible or applicable. For production of

Wax emulsions must accordingly be added suitable additives or emulsifiers.

[4] A variety of emulsifiers for waxes are known which can be classified as anionic, cationic or nonionic. The selection of suitable emulsifiers is carried out depending on the purpose, since the

different emulsifiers with different waxes are better or worse applicable. Since the differences mentioned above can not be explained scientifically, the selection of suitable emulsifiers is carried out by trial and error or empirically.

[5] Many of the substances used to emulsify waxes have disadvantages such as poor or poor biodegradability and the use of highly toxic compounds in the preparation of these emulsifiers (e.g., ethylene oxide).

To counteract the disadvantages described above and with the help of natural wax mergers sustainable cleaning, preservation and

To develop care products was found in the context of this invention that The use of biopetroleum in conjunction with essential oils provides an excellent emulsion effect of natural waxes, especially beeswax, in water.

The invention is therefore an emulsion of natural wax in water containing as an emulsifier naturally produced biopetroleum and essential oils. The natural waxes are beeswax or a mixture of beeswax with other natural waxes.

The new emulsions are characterized mainly by the exclusive

Use of natural, resource-conserving components as well as impressive fineness and high storage stability. Accordingly, they are good and easy to use in cleaning, preserving and care products.

[9] The use of the emulsions described above for the preparation of such agents and the simultaneous use of bioalcohol in these agents themselves are further objects of the invention.

[10] Furthermore, the use of synthetic components of the same species in these emulsions and the corresponding cleaning, preserving and care products is also part of this invention (e.g., short chain alcohols as substitutes for bioalcohol or various petroleum compositions as a replacement for the biopetroleum).

Petroleum is a petroleum distillate and has a boiling point of 180 to 250 degrees Celsius. It is thus between gas oil and gasoline. Thus, it is safer than gasoline or kerosene kerosene, harder to ignite than gasoline and more easily ignitable than diesel. The German Ordinance on Flammable Liquids indicates class A III kerosene, that is, the flashpoint that does not comply with Class A III

Boiling point may be confused, is between 55 and 100 degrees Celsius.

[12] Purified petroleum is composed of hydrocarbons consisting of 12 to 17 carbon atoms. Their arrangement is different, however. They occur as paraffins, naphthenes and alkylbenzenes. Alkylbenzenes are aromatic Compounds. The lower the proportion, the lower the precipitation of soot, pollutants and odors. With purified petroleum only a proportion of 0.1 percent of the aromatics is present and it is thus low in sulfur and aromatics. If low aromatics are included, it is also called paraffin oil. It is one of the alkanes and is, among other things, good for use with petroleum equipment.

[13] Petroleum is also suitable as a cleaning agent to remove highly adhering grease and dirt from surfaces.

[14] Biopetroleum is u.a. Made from algae with a high oil content and is an alternative to production from fossil oil. These algae are therefore used as a source of high-energy oils. In the cultivation of algae one distinguishes between open and closed systems and the oil content is of the

Cultivation conditions. A comprehensive presentation of the

Connections is u.a. in US Pat. No. 7,770,322 B2 (Continuous-batch hybrid process for production of oil and other useful products from photosynthetic microbes).

[15] Other sources of biopetroleum are cane sugar and corn. According to comparative literature, this invention is attached (Current Status and Potential for Algal Biofuels Production; A REPORT TO IEA BIOENERGY TASK 39; AUTHORS: Al Darzins, Philip Pienkos, Les Edye ).

[16] Unlike fossil derivatives, biopetroleum is more sustainable as algae or plants use C02 from the atmosphere for photosynthesis and growth.

Furthermore, algae can grow, for example, in salt water or non-pure water and thus burden compared to the production of petroleum derived from fossil oil resources only minimally existing fresh water resources.

[18] BFS Blue Enterprises, for example, is a Spanish company that offers biopetroleum and many other oil-based products (eg analytical-grade Biotech & Pharmaceutical Products). These have all been produced with the help of algae, while reducing CO2 emissions.

[19] Biopetroleum and other biofuels produced using natural resources as described above differ from conventional products in their significantly lower levels of sulfur as well as in the proportion of long-chain unsaturated fats.

[20] The American Society for Testing and Materials (ASTM) has already defined a standard according to which

Biofuels (D6751: Standard Specification for Biodiesel Fuel Blend Stock (B100) for Middle Distillate Fuels). Corresponding European and German standards regarding testing of biofuels also exist. The DIN EN 14214 e.g. describes the minimum requirements for biodiesel. Particular attention is drawn here to the different sulfur content.

[21] Bioethanol is defined as ethanol derived solely from biomass or the biodegradable fraction of waste or by the use of e.g. Algae was produced. If the ethanol is produced from vegetable waste, wood, straw or whole plants, it is also called cellulose-ethanol. Ethanol can be used as fuel additive in mineral oil derivatives for gasoline engines (ethanol fuel), as pure ethanol (E100) or together with other alcohols (eg methanol) as biofuel. A

Quality description is available with the DIN 51625. In Germany, mainly beets and cereals (wheat, rye) are used for the production of bioethanol, maize and other raw materials are of little importance. The most important form of bioethanol in Europe is the addition to gasoline. For example, super petrol is mixed with up to 5% bioethanol, E10 with up to 10%.

[22] Cleaning, preserving and care products based on the wax emulsions of the invention contain bioethanol with 96.6% to 100% alcohol content. It was found that the quality of the bioalcohol has a significant influence on the cleaning power. To produce bioethanol with 96.6% alcohol, two production steps are necessary: the fermentation and the distillation. In order to obtain 100% alcohol, the goods must undergo another process - the so-called absolutization.

[24] The quality of bioethanols - no matter how high percentage - depends on the manufacturer, the manufacturing process and above all on the quality of the raw materials used.

[25] Beeswax consists of myricin (proportion about 65% by weight), a mixture of esters of long-chain alcohols and acids, which is dominated by palmitic acid myricyl ester C15H31-COO-C30H61, in addition to free cerotic acid C25H51-COOH,

Melissinic acid and similar acids (12%), saturated hydrocarbons (about 14%), alcohols (about 1%) and other substances (such as bee-specific flavorings) (6%).

[26] Beeswax is well soluble in turpentine at room temperature, but also in heated alcohol. It has a density of 0.95 to 0.965 g / cm3.

[27] In contrast, about 85% of carnauba wax consists of esters of long-chain fatty acids (wax acids), ω-hydroxycarboxylic acids and aromatic carboxylic acids such as cinnamic acids. The alcohol component is fatty alcohols (wax alcohols) and diols. In addition, each about 2-3% of unesterified diols, long-chain wax acids such as behenic acid, carnaubaic acid, cerotic acid, lignoceric acid or melissic acid, wax alcohols and saturated hydrocarbons are also present.

[28] Essential oils contain secondary phytonutrients that can be used to attract insects for pollination, keep pests out or against

Protect diseases (eg caused by bacteria or fungi).

[29] Essential oils are composed of many different chemical compounds. They are fat-soluble but contain no fats. In contrast to fatty oils, essential oils evaporate without residue. In water they are only very slightly soluble. At atmospheric pressure, its boiling point is much higher than that of water, but overheated water vapor over-distils it. They usually have one Lower density than water and therefore form floating on the water surface liquid droplets (an exception is, for example, cinnamon oil).

[30] Orange oil is obtained by cold pressing the ripe fruit peel of the orange Citrus sinensis. It is next to clove leaf oil and eucalyptus oil to the cheapest essential oils. Orange oil is a yellow to reddish-yellow liquid. The density is 0.843 g cm-3. The (+) - limonene is with more than 90% main ingredient of the orange oil. In addition, there are still the aldehydes Octanal and Decanal, Sinensal and octyl and Nerylacetat. The ester content varies depending on the cultivation region.

[31] Orange oil is mainly used for flavoring beverages, sweets and perfuming household products, as well as in biological wood preservatives and paint thinners. Moreover, it is the main ingredient of many label removers. Furthermore, it is very popular as aroma oil in fragrance lamps

Raumbeduftung.

[32] Bitter orange oil is extracted from the peel of Citrus aurantium (Sicily, Spain). It has a more tangerine-like scent and a bitter aroma. It is used for the flavoring of liqueurs and scented water.

[33] For the purposes of the invention, orange oil is preferred as part of the emulsions, but the invention extends to all essential oils.

[34] In the emulsions of the invention, biopetroleum is generally used in amounts of not more than 15%, based on the total weight of the emulsion. Preference is given to contents of 10%, in particular between 1 and 10% by weight, or between 0.0005% by weight and 1% by weight, depending on the desired cleaning, preserving or care requirements for different applications

different natural or artificial surfaces.

Suitable waxes for the emulsions according to the invention are all known waxes of natural and synthetic origin, preferably those which are particularly suitable for use in cleansing and care products. When Examples of natural waxes are carnauba and candelilla wax, as examples of synthetic waxes called the polyethylene and Montanesterwachse.

[36] In the emulsions of the invention, the waxes are contained in amounts of up to 15%, based on the total weight of the emulsion; Preferably, the wax content is between 1 and 10 wt .-%, or between 0.001 wt .-% to 1% wt .-%, - depending on the desired cleaning .Konservierungs or care needs for

different applications on different natural or artificial surfaces.

For the preparation of the emulsions, which in the simplest case contain no ingredients other than beeswax, biopetroleum, bioethanol and water, one usually starts from a prefabricated mixture of liquid wax and emulsifier and then stirs either this mixture in water or, conversely, water into this mixture. In both cases, the emulsion is subsequently prepared without more vigorous stirring.

[38] Although emulsions consisting only of biopetroleum, bioethanol and water are preferred within the scope of the invention, it is of course also possible to add further auxiliaries to these emulsions for special fields of use. Mention may be made here primarily of additional emulsifiers, which may originate from all known classes and comprise both nonionic and anionic and cationic emulsifiers, and coemulsifiers, for example, alkalis, amines or soluble polymers. The proportion of these additional emulsifiers and

Coemulsifiers are generally lower than the proportion of biopetroluenes. Examples of further auxiliaries are preservatives and substances for lowering the freezing point. In addition, substances such as dyes, perfume, preservatives, plasticizers, solvents, surfactants and

Containers be contained.

[39] The new emulsions are preferably used for the production of cleaning, preserving and care products, in particular for the production of cleaning and care products for smooth metal surfaces (eg chromium and non-ferrous metals and non-ferrous metals), glass, mirrors, smooth plastic surfaces (such as gelcoat). and on paints or varnishes as well as used on furniture. Furthermore, they are used in particular for the production of cleaning, preserving and care products for rough surfaces such as

Natural woods used outdoors and indoors. The agents also have an advantageous effect on shoes, leather, as well as on carpet and other fibers.

[40] The amount of wax emulsion that is used to prepare these agents can be chosen largely arbitrarily and depends on the amount of wax that should be included in the finished product.

[41] The corresponding cleaning power can be enhanced by the addition of essential oils. They are easily incorporated into the emulsions and are used in the

Basic recipe used together with water and alcohol. The cleaning power of the corresponding funds is thus essentially explained by the basic recipe. Since the ethereal oils and the alcohol evaporate after the cleaning step, a sealing of the surfaces by polishing can be achieved in a subsequent working step.

[42] In the emulsions according to the invention, essential oils are generally used in amounts of not more than 3%, based on the total weight of the emulsion. In particular, contents of 0.0005% to 1% are preferred - depending on the desired cleaning. Preservation or care requirement for different applications on different natural or artificial surfaces.
