Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention specifies the following two types of alkaline aqueous chlorate solutions.
The purpose of the present invention is to provide a stable detergent composition containing various types of surfactants, which has bleaching, disinfecting, and sterilizing effects, and which prevents the field of sodium hypochlorite over a long period of time.

(Prior Art) Submerged chlorates represented by sodium chlorate are widely used for purposes such as bleaching, sterilization, disinfection, and deodorization. Recently, it has also been proposed that by adding a surfactant to impart penetrating power, it can be used as a laundry detergent for clothes, a mold remover, and other household cleaners. However, since sodium chlorate is generally a strong oxidizing agent, when a general surfactant such as soap is added, the surfactant will be salted out or decomposed, and the next The stability of sodium dichlorate is also significantly inhibited. This tendency is remarkable when a fragrance is added to the sodium chlorate-surfactant system, especially for the purpose of masking the chlorine odor.

In order to solve this problem, for example, the general formula; R-C-R'-Y
The total number of carbon atoms in R and R' is 17, and X is -CooNa,
A cleaning composition containing a surfactant represented by (SO3Na, etc.) (Special Publication No. 4F5-7976), sodium hypochlorite and a sulfonate of polyoxyethylene alkyl phenyl ether sulfate, which is an alkaline substance. A bleaching and sterilizing cleaning agent characterized by containing water (Special Publication Publication No. 45-4
No. 857), (A) hypochlorite 0.5 to 12% by weight,
(B) Alkaline substance [0.1 to 4% by weight and (C) agent 0
．． 01 to 1.0% polymerization, and component (A): (
B), (A): (C) and ((A) + (H)): C
Liquid sterilizing bleach compositions (Japanese Patent Application Laid-open No. 81099/1983) have been proposed in which the tjl ratio of tjl falls within specified ranges.

(Problem B to be Solved by the Invention) However, the detergent compositions proposed above do not satisfy all of the required performance as a detergent, and in particular, the detergent compositions do not satisfy all the performance requirements as detergents. There is a need for cleaning agents that are stable over long periods of time and have little decomposition.

(Means for Solving the Problems) In view of the above-mentioned problems, the present inventors have conducted extensive research, and as a result, two types of specified surfactants have been added to an alkaline solution of sodium hypochlorite (hereinafter also referred to as Na 010). The inventors have discovered that the above-mentioned problems can be solved and the desired objectives can be achieved by combining and blending the following, and have come to propose the present invention. That is, the present invention is a cleaning composition in which (a) an acylamino acid or a salt thereof or an acylmethyl taurine salt and (b) a surfactant consisting of a fatty acid soap are blended into an alkaline aqueous solution of hypochlorite.

Known alkaline aqueous solutions of sodium chlorate used in the present invention can be used without any particular restrictions, but the following are available chlorine: 1.5-13% caustic alkali 0.5-5. Generally, an aqueous solution containing 0.5 to 4% by weight of common salt is used, particularly an amount of available chlorine of 3 to 8% by weight, and 0.5% by weight of caustic alkali. F1-21jf1% and salt 1
Solutions containing ~2.5% by weight are preferably used.

If the effective chlorine content is less than 1.5ji mass%, the effects of bleaching, sterilization, disinfection, deodorization, etc. will be small; on the other hand, if it is greater than the tag or mass%, the stability of the next production sodium chlorate will be affected. Moreover, caustic alkali is added to suppress the decomposition of sodium hypochlorite, and if it is less than 0.5% by weight, its effect will not be exhibited.

The most important feature of the present invention is that an acylamino acid or its salt or an acyl methyl taurine salt and a fatty acid soap are blended as a surfactant into the above-mentioned NaeO solution. Since it functions without being salted out or decomposed, the decomposition of sodium chlorate is also prevented. Examples of such acylamino acids and salts thereof used in the present invention include sodium cocoyl sarcosine, lauroyl sarcosine,
These include sodium lauroyl sarcosine, potassium lauroyl sarcosine, sodium myristoyl sarcosine, sodium balmitoyl sarcosine, oleoyl sarcosine, sodium lauroyl methylalanine, and the like, among which lauroyl sarcosine and sodium lauroyl methylalanine are preferred. In addition, examples of the acylmethyltaurate salt include sodium N-cocoylmethyltaurate,
Sodium N-lauroylmethyltaurate.

These include N-myristoylmethyltaurine sodium, N-balmitoylmethyltaurine sodium, and N-stearoylmethyltaurine sodium. In addition, the fatty acids used in the present invention include, for example, C & ~
Cs is a saturated acid. Sodium salts or potassium salts of lauric acid, myristic acid, balmitic acid, stearic acid, oleic acid, sodium 2-ethylenehexanoate, sodium 2-ethylenehexyl sulfate, sodium neodecanoate, etc. can be used without particular restriction, but in particular 2 - Sodium ethylhexanoate is preferred.

The cleaning composition of the present invention contains 0.04 to 5%, preferably 0.5 to 2% by weight of the above-described acylamino acid or its salt or acylmethyltaurine salt and a fatty acid soap based on Na (10% solution). It is preferable to contain 0.06 to 4% by weight, preferably 0.5 to 2% by weight.
If the content of each surfactant is less than the lower limit of the above range, the surfactant will not have the desired effect;
On the other hand, if it exceeds the upper limit of the above range, it is not preferable because decomposition of sodium hypochlorite is accelerated.

Further, the ratio of the acylamino acid or its salt or acyl methyl taurine salt as a surfactant to the fatty acid soap is preferably 1:1.5 to 1:2.5 in terms of weight.

The method for preparing the washed S silicate of the present invention is not particularly limited,
Generally, a method is used in which a predetermined surfactant is prepared in advance, and then the surfactant is mixed with an alkaline aqueous solution of sodium hypochlorite containing a predetermined concentration of sodium hypochlorite, caustic alkali, and common salt. At this time, in addition to the above-mentioned components, it is also possible to use water, fragrance, and other known surfactants to the extent that they do not have an adverse effect. In particular, one of the major features of the present invention is that the decomposition of sodium hypochlorite is suppressed even in systems containing fragrances.

(Effect) As described above, according to the present invention, the detergent obtained by combining the specified 2fIj type surfactants suppresses the decomposition of sodium hypochlorite over a long period of time. Therefore, it is effective as a bleaching agent for clothes and as a mold remover.
