As a result, a versatile detergent in powder form can be obtained. Fifth step The product obtained in the first step is sieved with a separator, and the powder (particle diameter is about 0.8 mm) on the sieve is put into a pulverizer and pulverized. This is mixed with the powder that has passed through the sieve in sieving.

Stir for ~ 20 minutes. In this way, a powdery detergent for laundry is obtained.

The versatile detergent obtained in the fourth step can be widely used as a shampoo, a dish / vegetable detergent, a face wash, a sanitary equipment / carpet detergent, a dry cleaning agent and the like.

The detergent obtained in the fifth step is mainly used for washing clothes such as cotton, hemp and synthetic fibers. As described above, according to the cleaning agent of this example,
It has the following advantages. (1) An excellent detergency is exhibited by the surface-active force of a plurality of anionic or nonionic surfactants. In addition, the organic chelating agent and citric acid or its salt exert the effect of capturing the dirt component, and the detergency is enhanced. Therefore, it is not necessary to prepare multiple cleaning agents according to the application,
One type of cleaning agent can be used for various purposes such as shampoo, dish detergent and laundry. (2) The cleaning agent does not contain conventional ABS or LAS,
80% by weight or more of natural components such as sodium carbonate and sodium sulfate as regulators, fatty acid palm oil diethanolamine and polyoxyethylene alkyl ether as surfactants are contained. Therefore, the toxicity is low, and the risk of damaging the skin and internal organs can be reduced. (3) It suffices to stir, mix, and heat the raw material components with a stirrer or a heating device, which does not require a special device, can be easily manufactured industrially, and can reduce the manufacturing cost. (4) Since the cleaning agent of this example is based on a natural component, it can be easily decomposed by microorganisms to prevent the possibility of polluting the environment.

By the way, the results of tests conducted using the cleaning agent of this example are described below. (A) Measurement of biochemical oxygen demand (BOD), chemical oxygen demand (COD), and total phosphorus For water after performing a predetermined cleaning test, BOD, CO
D and total phosphorus were measured. The results are shown in Table 1.
All measurements were performed according to JIS K 0102.

[0023]

[Table 1] As shown in Table 1, the cleaning agents of the examples are BOD and COD.
Both the values of total phosphorus and total phosphorus are low, indicating that there is little risk of polluting the environment. On the other hand, the commercially available synthetic detergents have a small total phosphorus content, but have high BOD and COD values. Further, it can be seen that powdered soap is high in BOD, COD and total phosphorus and pollutes the environment. (B) Cleaning test A cleaning test was performed under the following conditions. However, the total amount of the two types of enzymes was changed to 0.25%, 0.5%, and 1.0%. In addition, a cleaning test was performed in advance on the case where the object to be cleaned was immersed in the cleaning agent for 1 hour and when it was not immersed.

Washing temperature: 20 ° C., Washing time: 10
Min, rinse time: 15 min. As a result, it was found that the cleaning effect was enhanced as the total amount of the two kinds of enzymes was increased. Further, it was found that the cleaning effect is enhanced when the article to be cleaned is immersed in the detergent for 1 hour in advance, as compared with the case where the article to be cleaned is not immersed in the detergent in advance.

The present invention may be embodied by changing the configuration as follows, for example. (A) Use sodium ethylenediaminetetraacetate, glycine, dimethylglyoxime, etc. as the organic chelating agent. (B) As a regulator, potassium carbonate, potassium sulfate,
