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 to form a stable oil-in-water emulsion.
Moreover, in producing this stable emulsion,
The present invention relates to a processing agent that can be produced simply by mixing and stirring the processing agent without requiring a heat treatment step.

(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 the amount is large, but in recent years, cheap oil has been imported in large quantities, making it unprofitable for companies, and collection has become difficult, so they have to dispose of it themselves. There are more and more situations where I have to do this.

In addition, regardless of whether the edible waste oil collected by a collection company is reprocessed, such as by making into 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, it seems to be disposed of by soaking it into cloth or paper, but this is time-consuming and the amount of waste oil produced is relatively small, so it is often disposed of directly into the sewer.

In this case, oil will settle in the drain pipe and solidify with other residue, causing a blockage in the drain pipe.
Furthermore, as mentioned above, it also causes problems in terms of environmental hygiene.

There have also been proposals to solidify edible waste oil for disposal or 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. However, the work process was time-consuming and required a lot of time.

(Problems to be solved by the invention) This invention solves various ω1 problems in view of the above-mentioned points.
As a result of our research, we aim to propose a processing agent for edible waste oil that can be safely and easily disposed of even by housewives, and that does not pose any environmental health problems.

The following conditions are required when processing edible waste oil: (1) It must be possible to work safely without the use of poisonous substances or powerful drugs (2) Complex processes such as heating and cooling treatments are not required (3) Working time It is necessary to satisfy various conditions such as (4) the measurement error should be small (5) it should be 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. Based on this knowledge, we have proposed this invention.

(Means for Solving the Problems) As a processing agent for producing 1 q of stable oil-in-water emulsion from edible waste oil, which is the object of this invention, polyoxyethylene nonionic surfactant, Oxyethylene alkyl ether (number of moles added: 5), polyoxyethylene alkyl phenyl ether (number of moles added: 5),
Most preferably, polyoxyethylene fatty acid ester (number of added moles is 3) is selected.

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

Furthermore, 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, if the same nonionic type or polyoxyethylene type nonionic type is used, the same effect cannot be achieved.

Furthermore, as for anionic surfactants, tests were conducted on sulfonic acid type alkylbenzene sulfonates, sodium dialkyl sulfosuccinates, sulfuric acid ester type polyoxyethylene alkyl ether sodium sulfate (1 cum), commercially available dish detergents, etc. None of the stable oil-in-water emulsions were tested.

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.

(Explanation of Examples) Examples 1 to 3 (in the case of a single treatment agent) Example 1 Add 1Qcc of the treatment agent polyxyebrene alkyl ether to 100CC of edible waste oil and dissolve with stirring to obtain 1q of the mixed liquid.

Example 2 5 cc of polyoxyethylene fatty acid ester processing agent was added to 100 cc of edible waste oil and dissolved with stirring to obtain a mixed solution.

When 400 cc of water is mixed into this liquid mixture and stirred, a milky white emulsion is produced.

(Result) Emulsion of one treatment agent is less than 5cc...No effect 5cc~20c
c...Complete emulsification stability (even after 30 minutes, emulsification was good and oil did not resurface) Lifetime degradability was the best among Examples 1 to 3.

=The price is the most expensive among Examples 1 to 3.

= The rate of dissolution of the treatment agent and the rate of emulsion with water begin immediately upon mixing.

Example 3 Add 5 cc of processing agent polyoxyethylene alkylphenyl ether to 100 cc of edible waste oil and dissolve with stirring to obtain 1 q of the mixed liquid.

When 400 cc of water is mixed into this liquid mixture and stirred, a milky white emulsion is produced.

(Result) = Emulsification of processing agent 5cc or less...No effect 5cc~20C
C...Completely emulsified and stable (:i: Even after 30 minutes, emulsification is good and oil does not resurface) Lifetime degradability is the worst among Examples 1 to 3.

-The price is the cheapest among Examples 1-3.

=5! The rate of dissolution of the physical agent and the rate of emulsification with water begin immediately upon mixing.

Examples 4 to 6 (in the case of a mixed treatment agent) Example 4 5 cc of a treatment agent consisting of 10 to 40 parts by weight of polyoxyethylene alkyl edel and 60 to 90 parts by weight of polyoxyethylene fatty acid ester to 100 cc of edible waste oil Add and stir to dissolve, then add 1q of the mixture.

When 400 cc of water is mixed into this liquid mixture and stirred, a milky white emulsion is produced.

Example 5 Processing agent 5c consisting of 100 cc of edible waste oil, 10 to 40 parts by weight of polyoxyethylene alkyl ether, and 60 to 90 parts by weight of polyoxyethylene alkyl phenyl ether

Example 6 is suitable in terms of lifetime degradability and price.

It should be noted that the selection or mixing of ingredients is done by calculating and blending synergistic effects so as to mutually enhance and improve efficacy. For example, Component Biodegradability Price Polyoxyethylene Alkyl Low Low Phenyl Ether Polyoxyethylene Alkyl Medium Medium Terpolyoxyethylene Fatty Acid High High Ester Test Example 1 After adding 100 cc of edible waste oil (components 1 to 10) and stirring and dissolving it. , add 400cc of water and add ti2 itch, but each 5.1
The emulsification status of 0.20 cc was investigated.

◎Emulsification stability Good ○Ya separation XComplete separation test example 2

In this invention, as a processing agent for promoting emulsification of edible waste oil, polyoxyethylene alkyl ether (additional mole number 5) in the ionic surfactant for polyoxyethylene type is used.
, polyoxyethylene alkylphenyl ether (I)
Since it uses polyoxyethylene fatty acid ester (additional mole number: 5) and polyoxyethylene fatty acid ester (additional mole number: 3), it is a treatment agent with excellent low toxicity, and does not require heat treatment or other treatments. Since both are liquid processing agents, they easily dissolve into each other as soon as they are mixed into the edible waste oil, and emulsion starts instantaneously, so they have the advantage of being easy to stir, and are safe and easy to work with.

In addition, this treatment agent can produce waste cooking oil as an oil-in-water emulsion, so when it is transported for disposal, it is much easier to transport than when the highly viscous cooking oil is sent through the drain pipe. This has the advantage of not only allowing smooth flow of water but also of not causing any adhesion to the drain pipe.

Therefore, it is a processing agent that can be disposed of in the sewer system without any problem, and can be expected to have favorable results when transported for reprocessing with outflow light.
