The increasing use of fertilizer and agricultural chemicals, the air pollution, etc have caused to contaminate farm products such as fruit and vegetables. The contamination has become more serious by treating the products with preservative to keep them fresh during international trades.
Some chemicals remaining on fruit or vegetables with careless washing, fatal to human body, may lead those who had eaten the fruit or vegetables to an incurable chemical poisoning or, severely, to death,
Such fruit as apple, pear and persimmon having peel and hard tissue may be out of trouble as long as they are taken with simple washing and peeling off. However, it is difficult to wash enough with water such fruit and vegetables as strawberry, grape, lettuce, crown daisy and cabbage, which have no peels or have soft tissue. Under the circumstances, a detergent suitable for washing such fruit or vegetables has been intensively required.
A desirable detergent should meet following requirements: 1) easily remove agricultural chemicals, bacteria, and other
contaminants from the surface of fruit or vegetable
with simple contact therewith; 2) do no harm to a person taken the residue thereof; 3) not cause skin damage or disease; 4) not deteriorate the freshness of the fruit or vegetable
to be washed; and 5) not pollute the environment after being discarded
Background of the Invention
Conventional nutrial detergents with good washing and disinfecting power may cause inflammation or roughness on skin due to the sulfonate anionic surfactant, a major ingredient thereof. It is required therefore to add mollifier or skin protecting agent thereto to weaken the toxicity. Such conventional detergents have another problem: environmental pollution.Though some bio-degradable detergents have been developed so far to solve the problem, they have only weak washing and disinfecting power and are expensive.
The present invention is based on the finding that polyoxyethylene sorbitan mono-laurate (20 E.O.) having been used as food additive or solubilizer can meet the aforementioned desirable requirements of detergent.
it is also found out that a mixture of polyoxythylene sorbitan mono-laurate (20 s.C.) and sucrose fatty acid ester can be suitable ingredients for the desirable detergent.
Furthermore, the inventors have noted that either polyoxyethylene sorbitan mono-laurate (20 E.O.) or a mixture of polyoxyethylene sorbitan mono-laurate and sucrose fatty acid ester could be combined with citrate salt such. as sodium citrate, potassium citrate or the mixture thereof for better washing power.
Summery of the Invent ' on Accordingly, it is an object of the invention to provide a novel use of the composition comprising polyoxyethylene sorbitan monolaurate (20 E.O,), citrate salts and, optionally, sucrose fatty acid ester.
The present invention is directed to a detergent composition which can easily remove such contaminants as agricultural chemicals, bacteria, etc from the surface of fruit or vegetables without sacrificing their freshness.
Thus, it is another object of the invention to provide a detergent composition adequate for fruit and vegetables.
Further the invention is directed to a detergent composition being rarely toxic to human body and scarcely polluting the environment.

Detailed De@tription of the Invention
According to the invention, for the above-mentioned purposes, there is provided a detergent composition containing as active ingredients polyoxethylene sorbitan mono-laurate (20 E.O.) citrate salt such as sodium citrate, potassium citrate or the mixture thereof and optionally sucrose fatty acid ester
The present invention also provides a detergent composition characterized in containing 5.00 - 20.00% bv weight of poiyoxyethylene sorbitan mono-laurate and 5.00 - 15.00% by weight of citrate salt in purified water.
The present invention provides a detergent composition comprising 5.00 - 20.00% by weight of polyoxyethylene sorbitan mono-laurate, 0.01 - 5.008 by weight of sucrose fatty acid ester and 5.00 1.004 by wight of citrate salt in purified water as well.
Polyoxyethlene sorbitan mono-laurate of the invention, widely known as 'Polysorbate 20 is a mixture of laurate esters of sorbitol and sorbitol anhydrides, consisting predominantly of the mono-ester, condensed with approximately 20 moles of ethylene oxide. It conforms generally to the formula:
wherein W+X+Y+Z has an average value of 20.
Conventionally, polyoxyethylene scrbitan mono-iaurate, free from harmful effect on human body, is used as additive and solubilizer.
According to the present invention, however, polyoxyethylene sorbitan mono-laurate is used , based on its washing power though not enough, as detergent to wash agricultural chemicals, bacteria and other contaminants off.
As mentioned before, the incomplete washing power of polyethylene sorbitan monolaurate can be complemented by preparing a mixture of polyoxyethylene sorbitan monolaurate and citrate salt, which exhibits excellent washing power.
Sucrose fatty acid esther employed in the present invention has been used conventionally as emulsifier, foamer and dispersing agent in food. It is fatty acid esters of sucrose, consisting primarily of the mono-ester having the structure:
wherein R means alkyl
Preferred are sucrose fatty acid esters consisting of the monoester and the di-ester (or the tri-ester) in the ratio of 4:1 to 3:2.
The alkyl in the sucrose fatty acid can be preferably substituted by (C10 - C15) alkyl group.
A prererable composition of the present invention contains by weight 5.00 - 20*00% of polyoxyethylene sorbitan mono-laurate and 5.00 - 15.00% of citrate salt. The content of sucrose fatty acid ester, if added, is preferably not more than 5*008 by weight.
It is important to note that the sum of the three active ingredients is in the range of 10.00 to 35.00% by weight.
The detergent composition containing not more than 10.00$ by weight of the three ingredients may not have enough washing power required. On the other hand, if the amount thereof exceeds 35.00% by weight, the detergent composition may cause undesirable adverse effects such as dermal irritation, freshness deterioration, etc.
The ratio between the active ingredients should be counted as an important factor for the invetion as well.
Preferred is a mixture of polyoxyethylene sorbitan mono-laurate and sodium citrate in the ratio of 20:5 to 10:10 by weight.
If sodium citrate is contained less than 25% on the basis of polyoxyethylene sorbitan monolaurate (20 E.O.) the resulting detergent composition may have weak washing powers On the other hand, if the content of sodium citrate exceeds 1005 on the basis of polyoxyethylene sorbitan mono-laurate, the two ingredients may not be mixed well enough to avoid separation.
The same principle can be appied to the detergent composition further containing sucrose fatty acid ester.
The rato of polyoxyethylene sorbitan mono-laurate and sucrose fatty acid ester verss citrate salt, according to the invetion is preferably in the range of 25:5 to 10:10.
The detergent composition of the invetion can further include recontamination blocking agent, organic builder and/or preservative.
The additives are selected from such conventional substances as are used in detergents for cher,-wa.e, fruit or vegetables and free from toxic effect on human body.
Preferredrecontamination blocking agent is water soluble polymer such as sodium carboxymethyl cellulose or polyethylene glycol.
Organic acid such as citric acid is preferred organic builder.
The additives should be added in such a way that they have no negative effect on the washing power of the resulting detergent composition.
A preferred detergent composition of the present invetion contains, by weight, recontamination blocking agent 0.05 to 1.00%, organic builder 1.00 to 2.008 and preservative 0.1 to 1.00%.
The additives may not function fully below the ranges while may be accompanied by adverse effect such as washing power weakening above the ranges.
The detergent composition according to the present invetion, being harmless and not irritative, can be applied to washing food-related products, for example, kitchen ware, fruit, vegetable, etc, especially to washing fruit or vegetable.
The detergent composition of the present invetion, due to its excellent biological degradability, scarecely pollute the environment after being discarded.
