Description

Detailed Description of the Invention "Technical Field" The present invention applies to wood, glass, synthetic resins, metals,
Related to cleaning agents used to remove stains such as paint.

"Prior Art and its Problems" Conventionally, various types of soaps and detergents T have been used as cleaning agents depending on the purpose, such as household, industrial, and medical purposes.

However, household soaps are manufactured by applying strong alkalis to oils and fats, but the resulting aqueous solutions are inevitably alkaline and cannot be said to be harmless to the skin of the human body.

Furthermore, most of the various conventional chemical detergents contain ingredients that are harmful to living things, and some are suspected of being carcinogenic or inflammatory to the human body.

Furthermore, the chemical detergents mentioned above are washed into rivers and oceans,
Problems have also arisen, including damage to and contamination of various marine resources.

``Object of the Invention'' The present invention was made to solve the problems of the prior art described above, and its purpose is to provide a cleaning solution that is harmless to the human body, does not pollute the environment, and has excellent cleaning power. - To provide an agent.

"Structure of the Invention" The cleaning and fitting agent according to the present invention is characterized by containing oil and fat, lecithin, and an alkaline to weakly acidic aqueous solution.

As described above, in the present invention, since lecithin, which is completely harmless to the human body, is used as an emulsifier, there is no fear of toxicity to the human body or environmental pollution. In addition, since the emulsifying effect of lecinthin is enhanced using an alkaline or weakly acidic aqueous solution, fats and oils are well emulsified and excellent cleaning power is exhibited.

The fats and oils used in the present invention may be any of natural vegetable oils, animal fats, mineral oils, and waste oils thereof, but preferably vegetable or animal oils that are harmless to the human body are used. do. In particular, in order to reduce the cost of the product, waste oil from household cooking oil and waste oil from commercial cooking oil used in restaurants, hotels, school lunches, etc. are suitable.

Note that when using these waste oils, it is preferable to remove floating food residue and the like.

Although lecithin may be artificially synthesized, natural lecithin obtained from animals, plants, microorganisms, etc. is preferably used, and for example, lecithin isolated from soybeans is preferred. Although the emulsifying effect of lecithin is well known, there is no example of using lecithin in a cleaning agent as in the present invention. Also, when used as a cleaning agent,
There was no idea that lecithin could be used in combination with an alkaline or weakly acidic aqueous solution to enhance the emulsifying effect of lecithin.

As alkaline or weakly acidic aqueous solutions, those derived from natural products such as plant ash or lye obtained from bird and animal bone charcoal powder are preferable for 1F, which is intended as a non-polluting cleaning agent.
If large production and low cost are desired, an aqueous sodium hydroxide solution or the like may also be used.

The pH of the aqueous solution is appropriately determined in the range of 1, for example, 5.8 to 12, depending on the LJ. In this case, the emulsifying effect of lecithin becomes more active on the alkaline side, and more excellent cleaning power is exhibited. Therefore, in applications that come into direct contact with the human body, such as for washing hair or washing dishes, use a weakly acidic or weakly alkaline solution to avoid irritating the skin, such as wood, glass, plastics, metals, etc.
In applications such as removing stains from paint, etc., it may be made to be slightly alkaline to strongly alkaline to exhibit stronger cleaning power.

- The blending ratio of the reporter component should be adjusted depending on the use of the detergent (concentration and pH) depending on the intended effect and the expected effect.Although there are various ways to do this, an example of a preferred example is as follows. For example, salad oil and white squeezed oil 1001, a weakly acidic aqueous solution with a pH of around 8.0, PH7,
Mix an alkaline aqueous solution with a pH of 0 to 12.0 or Q with a pH of 12.0 or higher, and 500 to 1oo01 of wood lye, and add 20 to 100 g of large σ lecithin to both of these components.
Add and mix. At this time, the reaction can be promoted by heating the liquid temperature to 50 to 60°C. The cleaning agent of the present invention produced in this manner has an emulsified state of approximately oil-in-water type.

In addition, the cleaning agent of the present invention contains various components in addition to the above. -1 can be done. For example, when waste cooking oil is used, the odor of food or the like will adhere to the fat and oil, reducing its commercial value. For this reason, it is preferable to add a small amount of wood vinegar with deodorization as a priority. Here, wood vinegar is a part of the component obtained by carbonization from a mixture of bark and wood chips of fresh oak, Japanese chinquapin, sakushi, etc.

It is a liquid with a distinctive burnt taste and sour taste, and is miscible with water, ethanol, and glycerin. PH is about 3.

By adding % of oil, it has the effect of removing the bad qualities of fats and oils. Furthermore, since wood vinegar has a low pH as described above, it is also possible to adjust the pH of the final product.

The detergent of the present invention can be applied to, for example, wood, glass, synthetic resins,
It can remove dirt from metals, paint, etc., and in the case of metals, remove rust from the surface, giving them a shine at the same time. In this case, in order to remove rust from metals and old stains from synthetic resins, it may be necessary to add some ingenuity to the method, for example, some physical treatment. In other words, you can use various methods to remove rust so as not to leave scratches on metals, or apply a cloth containing a water solution to stains on synthetic resins, wait a while, and then apply some force. IXJ''A effects can be obtained by applying techniques such as levering.These cleaning effects are due to the fact that the contained emulsions (soapy substances) physically remove the components in the dirt, such as by foaming. Chemically, it is produced by emulsification, and at that time,
It is thought that the #1# oil droplets in the water coat the surface of the object to be purified, giving it a glossy appearance. Furthermore, the facial cleanser of the present invention can be made into a hair cleanser by adding natural fragrances and the like.

"Embodiment of the invention" 100ml of household salad oil, 1 sentence of L clear wood lye (P)I 7.0-7.2), 30g of glossy lecithin granules of the Japanese Pharmacopoeia were added to the above m+t, and shaken occasionally. The aim was to accelerate the reaction. When a cloth was impregnated with the facial cleanser thus obtained and rubbed on the surface of the synthetic resin, stains on the surface could be quickly removed. Also, when I rubbed a rusty iron ashtray, the rust was removed and the surface became glossy.

Example 2 Household salad oil 100ml, wood lye supernatant liquid 11
(P) 17.5-8.0. When the reaction was carried out in the same manner as in Example 1 using 50 g of glossy lecithin granules from the Japanese Pharmacopoeia (liquid temperature: 40 to 50°C), the reaction proceeded more rapidly.
A good emulsified state was formed. This cleaning agent also had the same cleaning effect as above.

"Effects of the Invention" As explained above, according to the present invention, lecithin, which is harmless to the human body, is used as an emulsifier, so a facial cleanser that is free from toxicity to the human body and environmental pollution can be obtained. Furthermore, since the emulsifying effect of lecinthin is enhanced by using an alkaline or weakly brewing aqueous solution, oils and fats are well emulsified and excellent detergency is exhibited. Therefore, for example, it can remove dirt from wood, glass, synthetic resins, metals, paint, etc., and in the case of metals, it can also remove rust from the surface and make them shiny at the same time.
