The present invention relates to an enzyme-based bleach composition that decomposes protein stains at the same time as bleaching, and a method for producing the same. and a nonionic surfactant of the higher alcohol type or pluronic type, and an amphoteric surfactant of the alkyl betaine type or alkylimidazoline type, in combination with a combination of sodium percarbonate and an enzyme. In recent years, oxygen-based bleaches have become popular and are proving useful for coloring and patterning. The most commonly used solution is sodium percarbonate, but compared to chlorine-based products, it requires higher temperatures and soaking time, as well as other fatal disadvantages such as the fact that it does not react with blood or milk. The problem is that it has no effect on protein stains such as . Moreover, when used in combination with a detergent, there is a tendency to worsen the cleaning power of the detergent. The bleach composition of the present invention has improved this fatal drawback, and is formulated with enzyme-containing materials in a specific proportion without impairing the excellent properties of conventional oxygen-based bleaches. It also has the advantage of being easy to manufacture. In addition to sodium percarbonate, sodium perborate, sodium peroxide pyrophosphate, and urea peroxide are generally known as base materials used in oxygen bleaches.
Particularly recently, sodium percarbonate has been more widely used than other peroxides in terms of storage stability, safety, and bleaching effect. This bleaching agent mainly composed of sodium percarbonate causes the above-mentioned disadvantages. For example, bleaching agents based on sodium percarbonate have no effect on protein stains such as infant milk stains, meat stains on dish towels, and fish blood stains. Enzymes (proteases) are known to be effective in breaking down protein stains, and they have been commercially available in detergents.
Conventional washing methods were not fully effective due to problems such as the need to apply a certain temperature to the clothes and soak them for a certain amount of time. The present inventors thought of mixing bleach and enzymes because the conditions under which they work effectively are the same, and in this case, they combined an inorganic salt and a specific activator and mixed them into a combination of sodium percarbonate and enzyme. By doing so,
It has been discovered that a bleach composition with exceptional storage stability and bleaching action can be obtained, and the present invention has been achieved. Recently, research into enzymes for detergents has progressed, and enzymes that are stable to various surfactants and builders have been developed.For example, "Alcalase" (manufactured by Novo), which is currently used in many detergents, is made from titanium oxide. The enzyme is coated with polyethylene glycol.
Even if such an enzyme is used, there is a problem in that the activity of the enzyme decreases during storage when the enzyme is mixed with sodium percarbonate. Various attempts have been made to coat enzymes or bleach substrates as a method to prevent this problem, but none of them have been fully put to practical use.In the present invention, as detailed below, we have developed a method for coating enzymes or bleaching agents. A mixture of inorganic salts such as sodium carbonate or sodium sulfate, a higher alcohol type or pluronic type nonionic active agent, and an amphoteric active agent of the alkyl betaine type or alkylimidazoline type is combined in a specific proportion. By stirring and mixing, an oxygen-based bleach composition with excellent storage stability of enzymes was produced, and the present invention was completed. According to the present invention, the bleach composition contains 40 to 80% by weight of sodium percarbonate, 0.5 to 5% by weight of enzymes such as alkaline protease, 10 to 40% by weight of inorganic salts such as sodium carbonate, higher alcohols or A bleaching agent composition of an enzyme with excellent storage stability, characterized in that it contains a combination of a Pluronik-type nonionic activator and an alkylbetaine-type or alkylimidazoline-type amphoteric activator in an amount of 1.0 to 10% by weight. provided. In this specification, percentages and parts below are based on weight unless otherwise specified. In the present invention, the sodium percarbonate used as the bleach base material is sodium carbonate with hydrogen peroxide added, and is expressed as 2Na 2 CO 3 3H 2 O 2 and has an effective oxygen content of 13.0 or more. Apparent specific gravity is 0.7
-0.8 white powder, granules or granules are available, but granules or granules are preferred. Generally, sodium percarbonate is used in an amount of 40 to 80%, preferably 60 to 70%, based on the bleaching agent. The most suitable enzyme for decomposing protein stains is alkaline protease, which was developed for use in detergents, and as mentioned above, it is preferable to use an enzyme coated with an inactive layer. ``Alcalase'' from Novo Industries
Both products, which are commercially available under the trade name "Esperase", can be used, but since the aqueous solution of sodium percarbonate has a pH of 10.5 or higher, it is more desirable to use "Esperase", which is more stable in alkali.
Regarding the amount of enzyme blended, we obtained the knowledge that higher activity can be obtained when the enzyme is blended with bleach than the activity of the enzyme alone. (shown in Table 1)

ており、極めて有効なものであることがわかる。[Table] From the results in Table 1, it is clear that the enzyme has the highest activity when mixed with bleach at a concentration of 3%. or,
The enzyme concentration at which the cleaning effect is maximized with the standard amount of bleach used (10g/30) is also 2 to 3%, so the enzyme concentration to be mixed with bleach is 0.5%.
5.0% to 5.0%, preferably 1.0 to 3.0%. Examples of inorganic salts used in combination with sodium percarbonate include sodium carbonate, sodium sulfate, sodium bicarbonate, sodium tripolyphosphate, and sodium metasilicate, but those that do not reduce the bleaching activity of sodium percarbonate during storage are Sodium carbonate and sodium sulfate are used, and sodium carbonate is the most preferable from the viewpoint of stability of enzymes that can use both. Considering the stability of the enzyme, it is desirable to have a high proportion of sodium carbonate, but in terms of its effectiveness as a bleaching agent and the storage stability of sodium percarbonate, the proportion of sodium percarbonate should be 10 to 40%, preferably 20 to 30%.
% is good. The activator used in the present invention is a higher alcohol type or pluronic type activator as a nonionic activator, and as a higher alcohol type, an ethylene oxide (EO) adduct is particularly excellent. Further, as the amphoteric active agent, an alkyl betaine type or an alkylimidazoline type is used. When the nonionic activator and the amphoteric activator are used in substantially equivalent proportions, a greater enzyme stabilizing effect can be obtained. The amount to be added to the bleach is 1 to 10%, preferably 3 to 7%, and the addition of an activator is used to prevent sodium percarbonate and enzyme powder from scattering during manufacturing.
It is also clear that it works as an auxiliary effect to removing oil stains by dipping. It is also possible to add additives commonly known to bleach compositions, such as fluorescent brighteners and fragrances, if necessary. The method for producing this bleach composition is to first add sodium percarbonate, then add sodium carbonate and a premixed nonionic activator and amphoteric activator, followed by stirring with a powder mixer. The stirring conditions are that two stirring devices rotate at 32 rpm,
This machine is used because it is necessary to maintain the shape of each component while increasing the stirring capacity by using a device that revolves at 10 rpm. After stirring the above for 5 minutes, the mixture is stopped once, and then the enzyme "Esperase" is added and stirring and filling are carried out for 1 minute to obtain a product. Hereinafter, the present invention will be specifically explained using examples. Each test in the following examples was conducted as follows. (1) Storage stability of sodium percarbonate Bleach was placed in a polyethylene bottle and stored in a constant temperature bath at 40°C for one month, and the amount of effective oxygen in the sodium percarbonate in the bleach was measured after storage. Find the rate of Storage stability (%) = Available oxygen after storage / Available oxygen before storage x 100 (2) Storage stability of enzymes Enzyme activity was determined by the Agricultural Chemistry Society method for enzymes stored for one month in the same manner as above.Protease activity was measured to determine the residual activity rate. Storage stability (%) = Enzyme activity after storage / Enzyme activity before storage x 100 (3) Evaluation method for cleaning effect and bleaching effect Immediately put 10g of each bleach into a 50℃ 1 with stirring and perform a cleaning bleaching test Soak the black tea contaminated cloth and EMPA No. 116 (standard contaminated cloth mixed with blood, milk, and carbon) for 30 minutes.
After washing and drying these two types of treated fabrics, the reflectance at 510 nm is measured, and the difference in reflectance before and after treatment is taken as the cleaning/bleaching effect. Cleaning effect = Reflectance after EMPA cleaning - 10.8
(Reflectance under EMPA) Bleaching effect = Reflectance after washing black tea contaminated cloth - 42
(Reflectance of black tea contaminated fabric) Example 1 A bleaching agent was obtained by stirring and mixing a base material, an inorganic salt, an activator, and an enzyme having the composition shown in the table. As is clear from these results, in Comparative Product A, the storage stability of sodium percarbonate is good, but the stability of the enzyme is somewhat poor, and in Comparative Product C, the stability of sodium percarbonate is poor due to the large amount of inorganic salt. or,
Commercially available oxygen bleaches have excellent bleaching effects on tea-stained fabrics, but have no effect on EMPA-stained fabrics, whereas enzyme-containing detergents have excellent bleaching effects on EMPA-stained fabrics, but do not bleach black tea-stained fabrics. It has no effect at all. On the other hand, in the case of the product of the present invention,
Both the EMPA-contaminated cloth and the black tea-contaminated cloth showed excellent effects, and it was found that they had no problem in activity even during storage stability. Example 2 Table 3 shows the results of tests conducted in the same manner as in Example 1, with different blending ratios of various raw materials. As described above, the enzyme-containing bleaching agent of the present invention can maintain the bleaching effect and the cleaning effect of the enzyme by mixing an inorganic salt and a specific nonionic/ampholytic combination of activators in a specific ratio, and can be preserved. It can be seen that there are no problems with stability. It can be seen that the present invention is a bleaching agent for clothing, dishcloths, tableware, etc., which has excellent bleaching effect and protein stain removal effect, and is extremely effective.
