Description

TECHNICAL AREA

The invention relates to the use of the fruit pulp of fruits of the plants of the cucurbitaceae family (Cucurbitaceae) or of a juice or extract thereof as a cleaning agent for cleaning and care of surfaces and textiles, especially in the household and kitchen sectors, as well as a corresponding detergent based on the pulp of plants of the cucurbitaceae family ( Cucurbitaceae ), and its production.

BACKGROUND OF THE INVENTION AND PRIOR ART

Most conventional home and industrial cleaners are largely made from synthetic or petroleum based chemicals. Their ingredients are often aggressive, harmful to the environment and unhealthy for humans and animals.

Increasingly, sustainable cleaning agents based on renewable resources, for example those based on plants, are also being developed. Such sustained cleansers, mostly based on extracts or dried and ground parts of plants, are usually a complex mixture of various plant constituents and are often only suitable for a very limited field of application. In addition, the conventional herbal detergents usually have only an insufficient cleaning effect.

The present inventors have surprisingly found that the use of the flesh of fruits of plants of the family Cucurbitaceae (Cucurbitaceae) or a juice or extract therefrom a significantly improved cleaning effect in the cleaning and maintenance of surfaces and textiles, in particular in the household and Kitchen area, can be achieved, so that this is particularly suitable as a basis for a corresponding detergent.

Pumpkin ingredients or extracts thereof are already commonly used in cosmetic products. These pumpkin ingredients are usually used in comparatively small amounts, based on the total cosmetic preparation. So describes the example FR2522500 cosmetic and also pharmaceutical products with anti-inflammatory and analgesic effects based on squash. Similarly, in King 1998, Pliny Secundus - Natural History Book 20 - Medicine and Pharmacology: Remedies The garden plants, the use of the juice of watermelon in ancient times as a cleanser to cleanse the facial skin and make shiny described.

Also in the field of household, dish and textile cleaning compositions have already been described, which may also have a certain proportion of pumpkin ingredients, such as in the CN105838517 . CN104946430 . CN104673506 . CN102746949 . JP11256189 , The cleaning agent described therein has in common that they have a complex composition of numerous ingredients, wherein pumpkin ingredients, based on the total composition, are contained only in a relatively small proportion and a significant proportion of conventional washing-active substances is added, which are added for the cleaning effect to be achieved , The CH705767 refers to sustainable detergents containing vegetable oil-based surfactants, among which pumpkin seed oil is also mentioned as a surfactant base.

Further cleaning agents of complex composition of various ingredients, which may also contain certain amounts of pumpkin constituents, describe the CN105733831 . CN105638785 . CN104450336 and KR100985229 ,

Also the CN104152306 describes a cleaning composition of complex composition based on vegetable raw materials, which contains various herbal ingredients, which awarded in a very general form a detergent effect. The CN102492577 and the CN104877809A describe detergents based on vegetable raw materials, in addition to pumpkin ingredients in particular limonene or lime and Panicum miliaceum and wheat germ oil powder, the degreasing detergent effect is explicitly attributed to these herbal ingredients. In the CN102492577 On the other hand, the pumpkin component is only granted a cosmetic effect, namely a skin-lightening effect.

The DE 10 2010 002 364 describes the use, inter alia, of juice or pulp of zucchini for the conversion or elimination of undesirable natural products in foods such as interfering phenols, anisols, sulfites, halogenated hydrocarbons and microbial contaminants, especially biofilms.

OBJECT OF THE INVENTION

The object of the present invention was therefore to develop a new sustainable cleaning agent, which overcomes the disadvantages of the conventional and known from the prior art detergent. In particular, the object of the present invention was also to develop a sustainable cleaning agent based on renewable raw materials with a comparatively simple composition and yet high cleaning action, which is suitable for a wide range of applications. In a further aspect of the invention, the new detergent should be light be accessible and easy to produce. The new sustainable cleaner should also be environmentally friendly and gentle on the treated surfaces. In addition, the new detergent should be characterized by the highest possible skin compatibility. Another object of the present invention was to provide a novel detergent having a high cleaning action against greasy soils. In particular, a new high-cleansing detergent should be provided on surfaces and / or textiles in household and kitchen areas.

A further aspect of the present invention thus also encompasses the use according to the invention in the industrial manufacturing sector (eg in the large-scale industrial food production) or in the automotive sector, in particular for the cleaning and / or care of surfaces against greasy and oily soils occurring there, for example during the cleaning of greasy abrasion contaminants eg on rims or industrial production machines.

Another aspect of the present invention comprises the use according to the invention for cleaning textiles such as e.g. the below, by application in washing machines. The term "textiles" encompasses the textile structures produced by known processes from textile raw materials (natural fibers, man-made fibers) and non-textile raw materials, such as, for example, Yarns, threads, ropes, woven fabrics, knitted fabrics, knits, braids, stitchbonded fabrics, nonwovens and felts etc. The use according to the invention for the cleaning of textiles comprises in particular the cleaning of textiles selected from the group comprising workwear and kitchen clothing, such as shirts, T-shirts, polo shirts, pullovers, (cooking or work) aprons and (cooking or work) jackets, smocks, pants and skirts, and overalls; Headgear such as caps, hoods, hats etc .; Household and kitchen textiles or other textiles for cleaning work areas such as towels, blankets, and cleaning cloths; as well as any textile protective clothing in the industrial manufacturing sector or in the automotive sector.

The use according to the invention is directed in particular to the cleaning and removal of greasy soiling. The term "greasy soiling" in the context of this invention encompasses any soiling or contamination by lipophilic (water-insoluble or sparingly water-soluble) substances, in particular by fats, oils or waxes, as well as soils containing such fatty, oil or wax components. It covers all levels of contamination, from a thin film of dirt or scattered speckles to persistent and coarse encrustations and baked or baked food residues. Included in particular are greasy soiling and encrustations of frying, roasting and other fats that are produced in the kitchen area, but also greasy soiling in the industrial manufacturing sector or in the automotive sector. by fuels, engine and lubricating oils, greasy sealants and lubricants, or water-insoluble soil deposits such as e.g. Automotive brake dust or other greasy abrasive debris that may be generated in the machine shop (e.g., in large scale food processing), etc.

In addition to the surprisingly outstanding cleaning effect of the pulp of plants of the cucurbit family ( Cucurbitaceae ) according to the invention, the inventors of the present invention have surprisingly found that this (as well as juices or extracts thereof) also has a surprising protective and care effect over the treated (purified ) Unfold surfaces. The protective and care effect in the context of this invention also includes some kind of surface sealing. It has been found, in particular, that by the use according to the invention the treated surface (s) have a markedly reduced tendency to become contaminated and can thus be protected to a certain degree against new contamination by the use according to the invention or these - compared to untreated ones Surfaces - can be delayed significantly. The protection against new pollution in the sense of this invention is characterized by over the untreated surface prolonged absence of above-mentioned dirt on the corresponding surfaces.

Furthermore, it has surprisingly been found that the treated surfaces can be finished by the use according to the invention. Surface finishing in the sense of this invention comprises e.g. the formation of a greater gloss and increased optical homogeneity of the treated surfaces compared to the untreated state, which can be achieved in particular, but not exclusively, on metallic surfaces such as stainless steel or aluminum.

The outstanding cleaning effect was also surprisingly found in the inventive use for cleaning textiles. Thus, the inventors found that by the use of the invention greasy soils, e.g. Grease stains, in textiles such as workwear or household textiles could be removed by simply washing in a conventional washing machine, without the need to add additional highly effective fat-dissolving special cleaner, which the fruit ingredients used in the invention in their cleaning effect on the performance of commercial detergents and special stain remover far out goes.

Furthermore, the outstanding cleaning effect was also surprising in the inventive use for cleaning kitchen utensils by simply washing in a conventional dishwasher, without the need to add additional strong effective fat-dissolving special cleaner or conventional dishwasher cleaners, so that the fruit ingredients used in the invention in their cleaning effect on the performance of commercial dishwasher cleaners goes far beyond and additionally has the care effect described herein and gives the cleaned utensils a surprising shine.

According to the invention, the use of the pulp of one or more plants of the cucurbitaceae family ( Cucurbitaceae ) in the form of a slurry or pulp is preferred.

The invention will be explained in more detail below with reference to examples. It will be apparent to those skilled in the art that these examples are exemplary only and do not limit the scope of the invention.

EXAMPLES A) Production examples 1. Preparation of an extract (filtrate)

To make an extract or filtrate, a squash (e.g., an Avalon or Hokkaido squash) or zucchini was minced and boiled with water (cooking time: about 15 to 20 minutes). The resulting slurry was filtered and the filtrate or extract was obtained.

2. Preparation of a slurry or pulp

To obtain a mush or pulp, a squash (e.g., an Avalon or Hokkaido squash) or zucchini was grated and slurried with water (room temperature). The pulp thus obtained was further used crude. To obtain a slurry, the pulp was cooked as described in Preparation Example 1 or the cooked fruit pieces from Preparation Example 3 were crushed (pureed) and the desired consistency was set by adding water.

3. Preparation of a brew

To obtain a broth, whole fruits or large fruit pieces of zucchinis were boiled with water (cooking time: about 15 to 20 minutes). Subsequently, the pulp pieces were removed and the resulting cooking liquor ( per se, ie without fruit pieces) continue to be used. Smaller particles in the cooking liquor can be removed by filtration if necessary.

For the production of an extract, a brew, a slurry or a pulp, it is equally possible to use other plant parts of one or more plants of the cucurbitaceae family (Cucurbitaceae) , such as, for example, leaves and / or stems.

B) Application examples

Cleaning of heavily soiled greasy surfaces in the kitchen / gastronomy, such as fryers (interior), heating coils, containers, grill bars, oven etc.

Example 1 Cleaning a heavily greasy grill filter

A Hokkaido squash was cut into pieces and soft-boiled with shell in water, then pureed and diluted with water. The resulting pumpkin porridge was applied to the grease-soiled grill filters. After a short exposure time, the grease soiling could be easily removed with a brush while gently scrubbing.

The thus cleaned grill filter also had a special shine.

The result is shown in Figures 1, 2 and 3.

Example 2 Cleaning a heavily grease-soiled grill plate

Zucchinis were cut into pieces and cooked soft with shell in water, then pureed and diluted with water. The resulting zucchini mush was sprayed onto the fat-soiled grill plates. After a short exposure time, the grease contamination could be wiped with a cloth without much effort.

The thus cleaned grill plate also had a special shine.

The result is shown in Figures 4 and 5.

Example 3 Cleaning a heavily grease-stained and encrusted oven

Zucchinis were cut into pieces and cooked soft with shell in water, then pureed and diluted with water. The resulting zucchini mushroom was sprayed onto the grease-soiled and heavily encrusted side walls in the cooking chamber of a conventional oven. After about 10 to 15 minutes of exposure time, the majority of the grease spills could be wiped off with a sponge without much effort.

The thus cleaned oven interior also had a noticeable gloss.

The result is shown in Figures 6 and 7.

Example 4 Cleaning of heavily grease-soiled and encrusted heating coils of a fryer

Zucchinis were cut into pieces and placed in the deep fryer containers along with water. The fryer heating coils were immersed in the water containing the courgette pieces and heated for about 20 minutes. Subsequently, the heating coils were allowed to stand immersed in the cooking liquor (brew) overnight. The next day, the incrustations from the heating coils could be scraped off with a conventional spatula with moderate effort.

The so cleaned heating coils of the fryer had a noticeable gloss, which was maintained even after subsequent use of the cleaned fryers over a longer period.

The result is shown in Figures 8 and 9.

Example 5 Cleaning of grease-stained kitchen utensils in a conventional domestic dishwasher and in an industrial dishwasher

Fat-soiled kitchen utensils such as cutlery, plates, etc. were given in a conventional manner in a domestic dishwasher and in an industrial dishwasher. Instead of the conventional household or industrial dishwashing detergent, 2 tablespoons of a courgette slurry prepared in accordance with Preparation Example 2 were filled in the respective dedicated dishwasher tank. The machines were then put into operation as usual.

The cleaned kitchen utensils had a surprisingly high gloss.

Comparative Examples

The cleaning of the equipment according to the application examples described above is usually carried out with highly effective chemical Speziel industrial cleaning agents.

It has been observed that by using the detergents of the present invention as described herein, the contaminants could be removed with significantly less force than when using the conventional industrial cleaners.

Furthermore, a noticeable gloss was observed on the surfaces cleaned according to the invention, whereas after treatment with conventional household or industrial cleaners, the cleaned stainless steel surfaces remain dull and dull.

In addition, it was found that when using the detergents according to the invention without gloves, the hands have no skin irritation or special skin dryness. Using conventional household cleaners without gloves, however, the skin was subsequently dry and irritated. The use of special industrial cleaning agents without gloves (as well as respiratory protection if necessary) is not possible due to the high chemical aggressiveness of the agents and is not explicitly permitted by the manufacturer.
