Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an underwear detergent, particularly a detergent composition suitable for cleaning women's underwear.

As is well known, secretions from women's internal and external genitalia, including menstrual blood, form stubborn yellow to tan stains that are difficult to clean with normal detergents and washing methods. For this reason, panties.

When it comes to underwear that is worn directly on the body, such as clothes, scanties, etc., consider the special characteristics of the item to be washed, and for example, do you put it in a small tub or washbasin when taking a bath? ? The stains are finally removed by using warm detergent solution, rubbing soap, etc. into heavily soiled areas, and rubbing and washing, but even with these methods, the stains are completely removed. It is extremely difficult to do so, and the reality is that female students and housewives often wear them only a few times and then throw them away. However, it goes without saying that such waste is undesirable in terms of resource conservation. Furthermore, in recent years, with the improvement of living standards, the field of women's underwear has become more and more fashionable, and as a result, panties and shorts are now available in various patterns, prints, and embroideries.

Luxury items such as lace have become popular, but in this case, glue is a shame because it can be worn only a few times and then thrown away.
Since it is extremely difficult to remove and clean, people are dissatisfied with the fact that they are not psychologically satisfied even if they are forced to wear them. The present invention solves these problems for many women,
The purpose is to provide a cleaning agent that can easily remove stains by simply dipping (7).

By the way, the reason why stains on women's underwear cannot be removed by normal washing is, of course, due to secretions unique to female genitalia, but the actual state of this stain is not yet scientifically clear. However, as a result of extensive basic research by the present inventors on stains on women's underwear in various age groups and during various menstrual cycles, we found that simply soaking for a short period of time is sufficient to remove stains from women's underwear, including those caused by menstruation. It has been confirmed that in order to clean the product, in addition to an appropriate surfactant, the coexistence of enzymes and peroxides, especially sodium percarbonate, is essential.

Nowadays, it is common practice to add small amounts of enzymes to laundry detergents to enhance their cleaning power, and also to add oxygen-based bleaches such as soda percarbonate, soda persulfate, or soda percarbonate. It is also well known that it enhances cleaning power. However, these generally relate to detergents for cleaning stains from ordinary clothing, and are not intended for cleaning stains caused by female genital secretions. Therefore, the inventor conducted further research with the goal of being able to almost completely remove contamination from women's underwear with only short-time soaking, and found that a composition that satisfies the following conditions is generally suitable for this purpose. Ta.

(1) Contains an anionic and/or hanonionic surfactant, an enzyme, an oxygen bleach, and a builder as essential components.

(2) The enzyme must be a mixture of proteolytic enzymes and other hydrolytic enzymes.

(4; Enzymes must be present in an amount of 10% or more based on the total amount of the composition.

(5) The amount of oxygen bleaching agent is 1000 or more based on the total amount of the composition.

(6) The builder is blended in an amount of 5% or more, preferably 10 to 20%, based on the total weight of the composition.

(7) Preferably, the oxygen bleach is sodium percarbonate.

(8) Preferably the builder is salt.

As described above, the present i-light underwear cleaning composition contains as essential components an anionic and/or nonionic surfactant, two or more enzymes, an oxygen bleach, and a builder. Examples of anionic surfactants include soaps, aliphatic sulfates such as sodium alkyl sulfate, sodium secondary alkyl sulfate, sodium amide sulfate, sodium glycol ether sulfate, sodium afurkylsulfonate, and sodium amidosulfonate. ,
Examples include aliphatic sulfonates such as sodium dialkylsulfosuccinate and alkylarylsulfone aromatic sulfonates. Examples of nonionic surfactants include polyoxyethylene alkylphenol, polyoxyethylene fatty alcohol, polyoxyethylene fatty acid, polyoxyethylene acid amide, polypropylene glycol/polypropylene glycol flock polymer (Pluronic type surfactant), and sucrose ester. is exemplified. It is preferable to use two or more of these surfactants in combination rather than using them alone.

Next, as the enzyme, a mixture of proteolytic enzymes and other degrading enzymes is used. Single proteases such as trypsin, chymotrypsin, and carboxypeptidase can be used as proteases, but in practice, animal and vegetable crude protease preparations such as pancreatin, papain, and promelain, or proteins of microbial origin are used. Preferably, a degrading enzyme preparation is used. These crude enzyme preparations contain various esterases, amylases, aminoglucosidases, and inmerases in addition to proteolytic enzymes, and the coexistence of these various degrading enzymes and isomerases has a synergistic effect for contamination removal. bring. However, since microbial proteolytic enzymes generally lack substrate specificity and tend to act strongly on human skin, pancreatin is most suitable for the purpose.

It is. Furthermore, the enzyme is 105 or more for the whole composition,
Preferably, the content is preferably 10 to 15%. This amount is significantly higher than the average amount of commercially available enzyme-containing detergents, which is about 1%.

Oxygen bleaches include soda percarbonate, soda persulfate,
Salt-type peroxides such as soda percarbonate, soda percarbonate, and sodium persilicate can all be utilized. However, according to the inventor's knowledge, sodium carbonate (Nag C206) is stable when dry and decomposes immediately when exposed to moisture to produce sodium bicarbonate and oxygen as a generator, but the bleaching effect of ice crystals is relatively low. It is particularly preferable for this purpose because it is mild, does not require a complementary color to dyes for ordinary colored or patterned objects, and has a sufficient bactericidal effect. The amount of oxygen bleach is preferably 15% or more, preferably within the range of 20 to 50%, based on the total composition.

Also in the composition of the present invention, the presence of organic or inorganic virgoo gives good results for the purpose of improving detergency.

Examples of bilgu include organic substances such as sodium CMC, sodium citrate, fatty acid amide, sodium naphthalene sulfonate, starch, urine accumulation, and/or sodium phosphate, sodium hydrogen phosphate, sodium polyphosphate, sodium carbonate, and sodium sesquicarbonate. Inorganic compounds such as , bentonite, sodium sulfate, and sodium chloride can optionally be used, but the latter, sodium chloride, is particularly useful because it has the effect of enhancing the action of enzymes.

The amount of bilgoo is preferably 5% or more of the whole rice, especially in the range of 10 to 20% when it comes to salt.

In addition to the above four ingredients, the composition of the present invention includes a flavoring agent, EDT.
Chelating agents such as sodium A, nitrilotriacetic acid, diethylenetriaminepentaacetic acid, and 1,2-cyclohexene diaminetetraacetic acid, fluorescent bleaches (fluorescent white dyes), and the like may be included.

The composition of the present invention is preferably 2.5 to 45y1 per dose. Preferably, it is packaged in 3y pieces.

In a separate questionnaire conducted by the inventors, many people answered that they wash their underwear when taking a bath, so each

002 One bag (3y) of this detergent composition is dissolved in 1 liter of warm water and used for washing one load of underwear (5 or less). Soaking may take about 20 minutes. With this recipe, you can wash an average of two semi-long girdles and one slip.

Example 3 Using the sample from the previous example, newly contaminated underwear of 21 women, including 7 pregnant women, was washed, and the cleaning rate was determined by setting the white discoloration before use as 100. The results were as shown in the table below (Table 1).

Table 1: Xjllll Reno Table Compensation - 1 Example 4 Three worn old shorts were repeatedly dipped in the detergent solution of Example 2 to examine the rate of recovery from white discoloration. The results are shown in the table below (Table 2).

As shown in Table 2, the detergent of the present invention has a greater bleaching ability than conventional general detergents when used (even though it is difficult to completely remove old stains). is obvious.

Note that, as shown in Example 3, complete cleaning is possible if the dirt is fresh.

Example 5 Contaminated cloth from which contaminated parts of three people's contaminated underwear were cut was stirred in sterile and dripless water to prepare a bacterial solution, which was then mixed with two types of commercially available synthetic detergents (X, Y) and Example 2. The composition was suspended in a hot water solution (39/l each), and the suspended liquid was added to GP at regular intervals.
and normal bouillon (NA) to examine the growth status of the bacteria. The results were shown in the table below (Table 3).

As shown in Table 3, the composition of the present invention has the effect of killing bacteria on underwear within 20 minutes, even against trichomonas, trichomonas, etc., so it is extremely hygienic as an underwear detergent. It is highly effective in preventing encephalitis not only caused by pathogenic bacteria such as Candida, but also normal encephalitis caused by intravaginal parasitic infection.

Example 6 To examine the detergency of various compositions of the composition of the present invention, formulations having the compositions shown in Table 4 below were prepared and compared with typical commercially available synthetic detergents (X, Y). (Excerpt from pre-menstrual stains) Table 4: For the test, 5 pieces of fresh pre-menstrual contaminated underwear were
1i11 with paddy temperature 45℃! , (containing sample composition 32)
A method was adopted in which the material was left in a room at 4 temperature for 20 minutes and then dyed with water. The results are shown in the table below (Table 5).

(Controls X and Y are typical commercially available synthetic powder detergents) From the results shown in Table 5 above, the enzyme content is at least 10%, preferably over 12%, the salt content is at least 12%, and the sodium percarbonate content is at least 12%. 20% or more is required, and it is especially effective when the other three elements, namely enzymes, sodium percarbonate, and salt, are in a certain ratio to the detergent, and it is a necessary condition that these kings are delivered. I can sense that.

Since the detergent composition according to the present invention contains a polyuretic enzyme, it tends to be slightly more irritating to the skin than general detergents. However, if you simply soak it in warm water, pick it up after a short period of time, and then rinse it, there is no risk of irritating your skin.The enzyme and oxidative bleaching agent in the composition of the present invention are sensitive to moisture. Therefore, it is preferable for quality control to separately apply an alkali-soluble coating as much as possible. Although the explanation above has focused on women's underwear, it goes without saying that it is also effective against stubborn contamination caused by secretions from hemorrhoids, perianal inflammation, etc., for both men and women.
