Description

Detailed Description of the Invention [Industrial Application Field] The present invention provides a hydrogen peroxide-containing liquid suitable for bleaching and removing mold from clothing, textiles, valves, and kitchen utensils, especially for bleaching clothing and tableware. Bleach composition.

[Conventional technology]

Conventionally, chlorine bleach, which has been commonly used as a liquid bleach, is cheap and has a powerful bleaching blade, but it has the disadvantage that it cannot be used on colored and patterned clothing because it discolors or fades the pigments in the clothing. Furthermore, in recent years, social problems have arisen such as chlorine gas being generated when chlorine gas is accidentally mixed with acidic cleaning agents, causing fatal accidents.

On the other hand, oxygen bleaches are superior in that they can be used on a wide range of clothing and do not cause the problem of chlorine gas generation. However, most of the oxygen-based bleaches currently on sale are powder types that use percarbonate (percarbonate) or perboric acid (perboric acid) as the main ingredient, and are not easy to use, and are especially effective against stains and other areas. It has the disadvantage that it cannot be used for coating against heavy dirt.

The use of hydrogen peroxide as a base for oxygen-based bleaching agents is widely practiced among laundry companies, especially laundry factories; The liquid has a hydrogen peroxide concentration of 35% by weight.
or 60% by weight (hereinafter simply referred to as %).

By the way, the decomposition reaction of hydrogen peroxide is Lo2 = P + OOH, pKa = 11.6 (Literature; Encyc
ropedia of Chemical Techno
(Vol. 14)), the lower the pH of the hydrogen peroxide solution, the more difficult it is to decompose. For this reason, commercially available highly concentrated hydrogen peroxide usually has a neutral or acidic pH.
However, even with this, it is impossible to completely suppress the decomposition, and in order to prevent the internal pressure from increasing due to the oxygen gas produced by decomposition and damaging the container, gas is added to the cap etc. It is sold in a special container that is designed to prevent it from escaping. On the other hand, in Japan, products with a hydrogen peroxide concentration of 36% or more are classified under the Fire Service Act.
Items with a hydrogen peroxide concentration exceeding 6% are designated as ``non-medicinal substances'' under the ``Poisonous and Deleterious Substances Control Law.'' Therefore, for safe use in general households, hydrogen peroxide must have a concentration of at least 6%. It needs to be diluted below. However, although high-concentration products of hydrogen peroxide are relatively stable, there is a problem in that when diluted, the stability deteriorates rapidly and they become easily decomposed.

For this reason, it is necessary to suppress decomposition with a low concentration hydrogen peroxide solution more than with a high concentration hydrogen peroxide solution. For this reason, various techniques have been proposed. For example, the Japanese Pharmacopoeia uses phosphoric acid, Babituric acid, uric acid, acetanilide, oxyquinoline, tetrasodium pyrophosphate, zenacetin, etc. are described. It is true that this may not be a problem for products such as pharmaceuticals whose distribution channels are kept relatively cool and dark, but for the distribution channels of daily necessities, there are extremely severe threats to the natural environment (for example, in the middle of summer). In warehouses like this, where the temperature exceeds 50°C during the day, it is necessary to provide better decomposition control.

Furthermore, JP-A-63-110294 discloses that chelating agents such as aminopolyphosphonate and ethylenediaminetetraacetic acid, BHT (dibutylhydroxytoluene) and MTBHQ (mono-t) are used as stabilizers for hydrogen peroxide.
-butylhydroquinone) is specified. Certainly, in terms of the decomposition rate of hydrogen peroxide, it is possible to reach a level that poses no practical problems by using these methods. however,
In terms of the amount of gas generated, this amount is insufficient.

For example, in a container with an internal capacity of 550 d, add 6% hydrogen peroxide solution (liquid ratio type is 1.og/ml!) at 25°C.
0mj! If the hydrogen peroxide concentration is reduced to 5.8% after being filled and stored at 50°C for one month, the decomposition rate of hydrogen peroxide is only 3%, but the amount of oxygen gas generated is 380%. - (50°C), and the pressure inside the container becomes about 9 atmospheres. In addition to this, the pressure due to the thermal expansion of the air sealed in the bottle head space from the beginning and the water vapor pressure of the balance water are also added, so an even greater internal pressure is applied to the bottle. Although it depends on the wall thickness of the container, regular polyethylene containers will not be able to withstand this internal pressure and will swell or even burst. Of course, there is no problem if the container is designed with a mechanism such as a cap that allows gas to escape, but apart from the case of high concentration products as mentioned above, in the case of low concentration products, the cost of the container is higher than the contents. It's too expensive and not economical.

[Problem to be solved by the invention]

Therefore, the present invention provides liquid oxygen containing hydrogen peroxide as the main ingredient, which further suppresses the generation of oxygen gas produced by the decomposition of hydrogen peroxide, and which does not cause the container to bulge or break even when filled into a plastic container. The purpose of the present invention is to provide a bleach composition based on the bleach composition.

[Means to solve the problem]

According to the present invention, when a fragrance having specific physical properties is added to a hydrogen peroxide solution, oxygen gas is generated due to the decomposition of hydrogen peroxide, with almost no effect on the decomposition rate of hydrogen peroxide. This is based on the knowledge that it is possible to suppress

That is, the present invention provides a liquid bleach containing one or more of (A) hydrogen peroxide and (B) a fragrance compound having one or less unsaturated bonds in the molecule. A composition is provided.

Hydrogen peroxide, component (A), used in the present invention is produced by various production methods such as electrolytic method and autoxidation method, and its concentration is 30%.
% to 60% JIS standard products are commercially available, and there is no particular problem in using any of these, and when used in the present invention, it is preferable to dilute it to about 2 to 10%. However, as mentioned above, in Japan, hydrogen peroxide solution exceeding 6% is classified as a deleterious substance, so in reality hydrogen peroxide concentration is 6%.
% cannot be sold as daily necessities.

To these concentrated hydrogen peroxides, the manufacturer usually adds a small amount of phosphates as a decomposition stabilizer (for example, according to the JIS reagent special grade standard, PO, totaling 0.0003%).
(below) is normal. However, when a concentrated hydrogen peroxide solution is diluted to the desired concentration, the decomposition stabilizer added by the manufacturer is insufficient;
It is advisable to add various decomposition stabilizers at the same time as dilution.

As a stabilizer used for this purpose, it is effective to use a combination of a chelating agent and an antioxidant. In other words, chelating agents prevent hydrogen peroxide from abnormally decomposing due to heavy metals by capturing them, and antioxidants prevent organic substances mixed in the composition from being oxidized by hydrogen peroxide. This is because it shows a preventive effect. Such chelating agents and antioxidants include
Although it partially overlaps with the compound described in JP-A No. 63-110294, ethylenediaminetetraacetate,
Aminopolycarboxylic acids such as diethylenetriaminepentaacetate, inorganic phosphorus compounds such as tripolyphosphate and birophosphate, 1-hydroxyethane-1,1-diphosphonic acid and 2-phosphono-1,2, 4-
Phosphonates such as tricarboxylic acids and the following formula (I)
Examples of antioxidants include polyaminophosphonic acids represented by compounds represented by (III) and organic phosphoric acid esters represented by phytic acid. Examples of antioxidants include DLα-tocopherol, gallic acid derivatives, butylated hydroxyanisole ( BHΔ), 2.6-tert-butyl-
Examples include 4-methylphenol (BHT). The amount of these stabilizers added depends on the concentration of hydrogen peroxide, but it is usually 0 to 5%, preferably about 0.01 to 3%.

Any one may be used. Surprisingly, it was discovered that adding a fragrance to a diluted hydrogen peroxide solution not only had almost no effect on the decomposition rate of hydrogen peroxide, but also had the effect of significantly reducing the amount of oxygen gas generated. . Moreover,
Fragrances have various structures, but those with more unsaturated bonds in their structure have a relatively more pronounced effect on suppressing gas generation at the beginning, but during long-term storage tests, the effect of suppressing gas generation suddenly increases. Oxygen gas will be generated, and in the end it will be about the same level as when no fragrance is added, and in some cases it may be worse than when no fragrance is added. However, when a fragrance compound is added at one location, an excellent gas generation suppressing effect was observed even during long-term storage, leading to the completion of the present invention.

Perfume and Flavor Chemical
als, (Aroma Chemicals),
Montclair, N. J. (1969). In addition, the compound having an unsaturated bond in the present invention refers to a chain unsaturated compound having a double bond (ethylene bond) or triple bond (acetylene bond) in the bond between carbon atoms among organic compounds, and a compound having an unsaturated bond in the ring. Alternatively, it refers to a cyclic unsaturated compound having these bonds in its side chain. Therefore, the present invention includes conjugated double bonds constituting a (4n+2)π electron system such as aromatic compounds, and C=0
, C=N.

Bonds such as and N=◯ are not included in unsaturated bonds.

In the present invention, in addition to the above-mentioned perfume compounds having one or less unsaturated bonds, a perfume compound having two or more unsaturated bonds can also be used to prepare a blended perfume.

However, in this case, it is necessary that at least 60% or more, preferably 70% or more of the blended perfume be a perfume compound having one or less unsaturated bonds. This is because if the percentage of the fragrance compound having one or less unsaturated bonds is less than 60%, a sufficient gas generation suppressing effect cannot be obtained.

The blending amount of the fragrance compound as component (B) is 0.005 to 2%, preferably 0.0% from the viewpoint of suppressing the generation of oxygen gas.
It is effective to set the content to about 1 to 0.5%. Incidentally, the fragrance compound may be used after being dissolved in a solvent such as a lower alcohol or a polyol such as hexylene glycol (2-methyl-2,4-bentanediol).

The liquid oxygen bleach of the present invention contains component (A) hydrogen peroxide, component (B), and a specific fragrance compound as essential components, and the content ratio of component (A) and component (B) is arbitrary. However, the mixing ratio of both components (^) / (B)
= 1.000/1 to 2/1 (weight ratio) is desirable.

The pH of the liquid bleach of the present invention is 7 or less, preferably 6 or less, particularly preferably 5 to 1, and the lower the pH, the more stable it is. As mentioned above, the pKa of hydrogen peroxide is 11.6.
Therefore, when the pH becomes alkaline, self-decomposition begins rapidly. In addition, when an aminocarboxylic acid-based chelating agent such as ethylenediaminetetraacetate is used as a stabilizer for hydrogen peroxide, if the pH is lowered to 3 or less, the chelating agent becomes insoluble in water and precipitates, resulting in the It is inappropriate to lower the pH excessively, as this will deteriorate the decomposition stability. In addition, in the case of a phosphoric acid ester type chelating agent such as phytic acid or a phosphonic acid type chelating agent, no particular disadvantage occurs even if the pH is lowered to about 1 to 2.

In order to adjust p+, inorganic acids such as sulfuric acid, phosphoric acid, and hydrochloric acid or organic acids such as toluenesulfonic acid and benzenesulfonic acid may be used, or the above-mentioned chelating agent or the below-mentioned anionic surfactant may be added in the form of an acid. (or hydroxide as necessary) It is best to adjust using a caustic alkali such as IJium or potassium hydroxide.

In addition to the above-mentioned stabilizing hydrogen peroxide, various additives may be added to the liquid bleach composition of the present invention as required. Among these, relatively important additives are various surfactants that are blended for the purpose of assisting in the dissolution and dispersion of ingredients and increasing the penetration power and cleaning effect. Particularly preferred as such surfactants are nonionic surfactants. Examples of nonionic surfactants include higher alcohols having 8 to 24 carbon atoms, polyhydric alcohols, fatty acids, fatty acid amides, fatty acid amines, alkylphenols, and alkylene synthetic alcohols obtained by oxidizing n-paraffins and α-olefins.

These include fluorine-based surfactants. The term "alkyl group" or "acyl group" as used herein is a general term for a saturated, unsaturated, or branched alkyl group or acyl group having an average carbon number of 8 to 20.

The amount of surfactant to be blended is usually about 0 to 20%, preferably about 0.1 to 5%.

In order to obtain effects such as stabilizing the liquid at low temperatures and preventing separation of the liquid at high temperatures, it is possible to add a hydrotrope agent in an amount of 0 to 30%, preferably 0.1 to 10%. Trope agents include - For boat fishing, short chain alkylbenzene sulfonates such as toluene sulfonate and xylene sulfonate, ethanol, ethylene glycol, propylene glycol, hexylene glycol, glycerin, etc. Examples include alcohol and polyhydric alcohol.

Compounds such as organic peracids can also be used to enhance the bleaching effect. Examples of such organic peracids include dodecane diperacid and monoperphthalic acid, and these organic peracids are preferably added after being adjusted to an aqueous dispersion system by a known method.

Further, in order to enhance the bleaching effect, a known activator for hydrogen peroxide may be used. Such activators include N-acyl, O-

Direct addition of these compounds impairs the stability of hydrogen peroxide, so they can be dissolved and dispersed in compounds such as solid fatty acids, or coated with solid fatty acids to prevent them from reacting with hydrogen peroxide during storage. It is best to add it in the form.

In addition, the product of the present invention may further contain appropriate amounts (about 0 to about 2% each) of various trace additives such as colorants such as pigments and dyes, silicones, bactericides, and ultraviolet absorbers.

〔Effect of the invention〕

According to the present invention, even if the hydrogen peroxide solution is stored for a long period of time, the amount of gas generated is small, so even if it is filled into an inexpensive container such as plastic that does not have a gas leakage mechanism, there is no risk of the container bulging or breaking. Since there is no such thing, it is extremely economical.

The present invention will be explained below with reference to Examples, but the present invention is not limited thereto.

〔Example〕

In the examples, the amount of gas generated and the swelling of the bottle were measured by the following methods.

Method for measuring the amount of gas generated: After filling a 500-capacity Erlenmeyer flask with a slotted stopper (total capacity about 555 m1) with water to the top of the opening, shielding it from light with aluminum foil, add 55-mL water with a pipette. Mark the surface of the water that was removed. I threw out the water and poured liquid bleach up to this point. After leaving it in a constant temperature oven at the specified temperature for 30 minutes, remove the glass tube with a common stopper (the length is 100mm).
cm, the length below the slit is 15 cm, and has a uniform inner diameter. ) Apply a thin layer of silicone grease to the slotted part, and insert it into the flask (be careful so that the meniscus is at the top of the slotted stopper). After confirming that the grease was spread all around the slot stopper, it was fixed using a spring or a rubber band. The stopper part was covered with aluminum foil and placed in a constant temperature bath at a predetermined temperature (the height of the water surface in the constant temperature bath was the opening of the flask) or in a constant temperature room for 2 hours, and the position of the meniscus was recorded. At the same time, a similar set was prepared using ion-exchanged water.

The sample was left for a predetermined period of time, the rise in meniscus was measured, and the amount of gas generated was calculated using the following formula.

Gas generation amount (-/ 500 mg> = (x x
o) rr (d/2) 'X = Amount of rise in the meniscus of liquid bleach (cm) The bleach composition was filled into a polyethylene cinder bottle (dropping volume 725-1, bottom wall thickness 0.6 mm, the bottom of this bottle was concave inward), and
After sealing the cap at 5° C. and storing it in a constant temperature bath at a predetermined temperature, the swelling of the bottle was observed with the naked eye at that temperature. Since this bottle has a cylindrical shape, when gas is generated and internal pressure increases, the bottom of the bottle bulges outward, which was evaluated based on the following criteria.

○: No change, the bottom of the bottle remains recessed inward) △: The bottom of the bottle was slightly swollen and became flat.

×: The bottom of the bottle swelled and the bottle tilted (or fell down).

Example 1 (A) Hydrogen peroxide (manufactured by Mitsubishi Gas Chemical: Reagent grade) 5.0% (B) Flavor compound (single fragrance compound with different number of unsaturated bonds) 0.2% (C: optional component) Various bleach compositions consisting of I-hydroxyethane-1,1-diphosphonic acid 0.1% (D: optional component) POB (p=9) lauryl ether 2.0% (E: optional component) ion-exchanged water, balance The products were prepared by changing the type of fragrance compound of component (B). In addition, the overall temperature is 10.0 with ion-exchanged water.
Immediately before balancing to %, the pH of the composition was adjusted to 4°5 using 0.1N sodium hydroxide solution and 0.1N sulfuric acid solution.
I adjusted it so that

Table 1 shows the amount of gas generated and bottle swelling of these various bleach compositions at 45°C. In addition, 45
30 days of storage at ℃ is equivalent to one year of storage at room temperature in the Tokyo area.

Table 1 (Continued) As is clear from Table 1, fragrance compounds with one or less unsaturated bonds have a high effect of suppressing the amount of gas generated, and as a result, the bottle bulges less. Recognize(
(Product of the present invention). For fragrance compounds with two or more unsaturated bonds, there is no particular problem with gas generation for up to about 14 days, but after 30 days or more, it may be about the same level as additive-free fragrance compounds, or depending on the case. It can be seen that more gas is generated than that. The residual rate of hydrogen peroxide is 45°C, 60°C.
Even after several days, more than 98% of each composition remained, and no major difference was observed.

Example 2 An example in which a blended fragrance is used is shown. A liquid bleach composition having the same composition as in Example 1 was prepared except for the blended fragrance shown in Table 2, and the effect of suppressing the amount of gas generation was examined. The results are also shown in Table 2.

As shown in Table 2, when using a blended fragrance consisting of 60% or more of a fragrance compound with one or less unsaturated bonds in the fragrance compound molecule, good gas flow is obtained, similar to the case of a single fragrance compound. It can be seen that it has an effect of suppressing the occurrence. Furthermore, the residual rate of hydrogen peroxide was over 98% in all cases, and there was no noticeable difference.

Example 3 Using the blended fragrance prepared in Example 2, bleach compositions were prepared in which the blending amount and the pH of the stock solution were varied, and the storage stability was evaluated. The results are shown in Table-3. All of these compositions showed good storage stability.
