Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a treatment agent for edible waste oil.

More specifically, edible waste oil is dispersed and diluted as fine particles in water and treated as a stable oil-in-water emulsion that is partially soaped, and a heat treatment process is required to produce this stable emulsion. The present invention relates to a liquid soap treatment agent that can be produced simply by mixing and stirring the treatment agents.

(Prior Art) Conventionally, the disposal of waste cooking oil used for frying food in general households and businesses has been a very troublesome problem.

For example, in the case of commercial use, the disposal is often entrusted to a collection company because it is a large amount, but in recent years, cheap oil has been imported in large quantities, making it unprofitable for the companies and collection tends to slow down, so they have to dispose of it themselves. There are many situations where this is necessary.

In addition, regardless of whether the edible waste oil collected by a collection company is reprocessed such as by making soap, if it is directly disposed of, it poses a serious problem in terms of environmental hygiene because oil is insoluble in water. .

In ordinary households, waste oil is treated with C by permeating it into cloth or paper, but this is time-consuming and the amount of waste oil is relatively small, so it is often poured directly into the water supply.

In this case, oil adheres to the drain pipe and solidifies with other residues, causing a blockage in the drain pipe.
Moreover, as mentioned above, it also causes problems in terms of environmental hygiene.

Other proposals have been made to solidify edible waste oil for disposal and to make it into solid soap, but these are dangerous because they use powerful chemicals such as caustic soda and require heating and cooling treatments. , the work process was time-consuming and required a lot of work time.

(Problems to be Solved by the Invention) This invention, as a result of various studies in view of the above-mentioned points, has been found to be able to be safely and easily disposed of even by housewives, but which also poses problems in terms of environmental hygiene. The purpose of this project is to propose a method for turning edible waste oil into soap, which can be processed in a timely manner.

The conditions required for processing edible waste oil are (1) N.
(2) Complex processes such as heat treatment and cooling are not required (3) The work time is short (4) There is little measurement error (5) ) It is necessary to satisfy various conditions such as being inexpensive.

As a result of extensive research, the present invention satisfies the above conditions, and the specific polyoxyethylene surfactant contained in the nonionic surfactant produces an oil-in-water emulsion that is stable at room temperature with respect to edible waste oil. This invention is proposed based on the knowledge, and moreover, it is an attempt to provide a processing agent that enables liquid soap emulsion formation.

(Means for Solving the Problems) As a processing agent for obtaining a stable oil-in-water emulsion from edible waste oil, which is the object of this invention, polyoxyethylene, an ionic surfactant for polyoxyethylene type, It is most preferable to select ethylene alkyl ether (number of added moles: 5), polyoxyethylene alkylphenyl ether (number of added moles: 5), and polyoxyethylene fatty acid ester (number of added moles: 3).

As shown in Test Example 1, even if the same polyoxyethylene type surfactant is used, a stable oil-in-water type emulsion cannot be obtained with polyoxyethylene polyoxypropylene glycol.

Further, even with the same nonionic surfactant, polyhydric alcohol-based and alkylrollamide-based sorbitan fatty acid esters, and fatty acid jetanolamide, the emulsion desired by the present invention cannot be obtained.

In other words, the same nonionic type or polyoxyethylene type nonionic type cannot be expected to have the same effect.

Regarding anionic surfactants, tests were conducted on sulfonic acid type alkylbenzene sulfonates, sodium dialkyl sulfosuccinates, sulfuric acid ester type sodium polyoxyethylene alkyl ether sulfate, commercially available dish detergents, etc. However, a stable oil-in-water emulsion could not be obtained.

Regarding the relationship between edible waste oil, processing agent, and water, from the results of Test Example 2, 100 cc of edible waste oil and 400 cc of water
CC or higher is required, so 400CC is optimal.

Next, ethanolamine, which is an alkanolamine ion, is added to a mixture of one or more selected from polyoxyethylene alkyl ether, polyoxyethylene alkylphenyl ether, and polyoxyethylene fatty acid ester to produce an oil-in-water emulsion. Blend.

If ethanolamine (mono, di, or tri) is added, it will react with fatty acids in edible waste oil as shown below.

Because it uses an added mole number of 3), it is a treatment agent with excellent low toxicity, and it can also be heated! 2! There is no need to process X-luck, and since both are liquid processing agents, they easily dissolve into each other when mixed into the edible waste oil, and emulsion starts instantly, making mixing work easy. It has the advantage of being safe and easy to work with.

In addition, this processing agent can produce liquid soap that has a cleaning effect on cooking waste oil, so compared to the case where the cooking waste oil, which has a strong caking degree, is sent through the drain pipe, by converting it into a liquid soap, it can create an interface by itself. Since it has an activating effect, it can remove deposits and allow for extremely smooth flow.

Therefore, it is a treatment agent that does not cause adhesion to drainage pipes, can be disposed of in sewers without any problems, and can be expected to have favorable results when transported for reprocessing with outflow light.
