Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to the composition of liquid cleaning agents such as shampoos and dishwashing agents.

[0002]

2. Description of the Related Art Surfactants used in detergents are primarily required to have excellent foaming properties and detergency, and are generally used for cleaning. As components, anionic surfactants such as soap, linear alkyl benzene sulfonic acid, alkyl sulfate, polyoxyethylene alkyl ether sulfate, and α-olefin sulfonic acid are used. Surfactants not only cause strong irritation to eyes and skin, but also have a problem of adverse effects on habitats of aquatic organisms due to wastewater entering rivers and the like.

[0003] For this purpose, a number of detergents containing surfactants, which are mainly mild to the skin surface, have come to be used. However, this did not solve all problems. Surfactants remain on the skin surface, hair, etc., and further penetrate into the skin, causing various adverse effects. In addition, the biodegradability is not sufficient, and a large number of surfactants currently used in various fields cannot be overlooked as a cause of environmental pollution. Above all, shampoos used daily and neutral detergents for kitchens have a direct effect on the skin surface because they are used as undiluted solutions, and even small residues can become serious due to repeated use. It can cause dermatitis and can affect internal organs. In addition, if the surfactant that has flowed into a river or the like is accumulated without being biodegraded, the ecosystem of aquatic organisms will be disrupted.

Accordingly, the present invention provides rich foaming properties and good foam removal during rinsing without impairing the cleaning effect, while reducing irritation to the skin surface and reducing the adverse effects on aquatic organisms. The purpose is to improve safety such as mitigation.

[0005]

SUMMARY OF THE INVENTION The composition of a shampoo and a dishwashing liquid in a liquid detergent is as follows. Anionic surfactants such as alkyl sulfates or salts thereof and soaps, and nonionic surfactants,
In a liquid detergent containing a foaming detergent component which is selectively mixed from an amphoteric surfactant or the like, an aqueous solution of Kumazasa (hereinafter referred to as Kumasa) component extract is used in an amount of 20 to 80 with respect to the liquid detergent. % By weight, sodium chloride 0.1-5
Liquid detergents such as shampoos and dish detergents containing% by weight. Next, the following method is used as the composition of the shampoo.

[0006]

[Effects] The following describes the aqueous extraction of Kuma-basa components and the use of salt as an essential requirement for the liquid detergent composition. Here, the aqueous extract of Kuma-basa bamboo is an aqueous solution of Kuma-basa bamboo extract,
It is an aqueous solution of aqueous alcohol extraction. Kumasasa is a nutrient-rich plant containing polysaccharides, flavonoids, chlorophyll, vitamin K, and various other minerals. One year after reaping, it grows back to its original state, and is full of vitality. Its medicinal effects are also various, but notable effects on the cleaning effect include an effect of suppressing itching, an effect of increasing wound healing power by activating cells, a bactericidal power, and a deodorizing power. In the bactericidal action, it was confirmed that it has antibacterial activity against Escherichia coli, Staphylococcus aureus, Micrococcus luteus, Proteus vulgaris, Pseudomonas aeruginosa, and the like. As for the deodorizing effect, a surprising effect was also found on deodorizing bodily and animal odors, body odors and fish and meat odors. In addition, as a result of experiments on the growth and survival of animals and plants, it has been proved that they have activity on living organisms. However, now, the addition of Kumasa baso ingredients to shampoos and dishwashing detergents is particularly effective in deodorizing the objects to be cleaned and protecting the skin surface, and is a toxicity test described in Examples for safety against living organisms. It can be said that this is an extremely effective action, as evidenced by the results of

According to the present invention, a salt is mixed with an aqueous solution of Kumasasa component extraction, which adjusts fluidity while maintaining activity against living organisms. Further, pumpkin oil is added to give the skin surface moisture and vitality by the action of the pumpkin oil component, and the hair roots are activated, so that a moist and healthy hair is created.

Further, with respect to the improvement of safety, which is the main object of the present invention, what action the composition of the present liquid detergent exhibits will be described below with reference to examples.

[0009]

EXAMPLE The safety of a detergent that comes into direct contact with the skin surface can be confirmed by measuring the toxicity of the organism. Here, of the reference data of the toxicity test of the conventional kitchen detergent and the toxicity test of the actual shampoo and kitchen detergent, among the shampoo,
It proves the point of action of the cleaning agent of the present invention with respect to a conventional cleaning agent.

First, as a reference, the results of a toxicity test of a kitchen detergent from Radio Technology Co., Ltd. “OK? Synthetic detergent Q & A” and “Experiment of a life club cooperative” are summarized.

According to the above-mentioned data, 29 types (100
ppm), and 11 others (0.005%). Half of the killing time of 6 medakas and the total number of killing times were recorded. As a result, it was found that all the one-hour or more lethal times were soap, and the difference between the soap and the synthetic detergent was very large. By component, the samples using higher alcohol-based polyoxyethylene alkyl ethers as surfactants were the most toxic. The complex soap containing the polyoxyethylene alkyl phenyl ether was also highly toxic, and the medaka stumbled around painfully, laying at the bottom two minutes later and dying soon. Linear: All linear alkyl benzene sulfonic acid sodium died within 15 minutes. Alkyl
The ones containing sodium sulfonate and polyoxyethylene alkyl ether lay at the bottom in 3 minutes, and sometimes become painful and crunchy, the gills turn red and the fins are dissolved. Was done. Alkyl
Detergents, which contain ether and sodium sulfate and are labeled as natural palm oil, showed that the medaka swam relatively quietly, and eventually sank with one or two, dying in 20 to 40 minutes. As for the zwitterionic detergent, the raw material is also described as pure vegetable, but medaka suffers and lays on the bottom in 10 minutes.
All died in minutes. Even zwitterions were not safe.
Alkyl glucoside and polyoxyethylene alkyl ether detergents are based on natural sugars, but half of them died in 8 minutes and all died in 27 minutes. It is described as above. From this result, even if the cleaning component is one that uses a natural material, there are various synthetic surfactants such as a moisturizing component, a softening agent, a polishing component, and the like. It is clear that the effects are large, the survival time is short in each case, and the toxicity is high in many cases. The long-term use of these cleaning agents in the kitchen is extremely disturbing, given that the detergent components remaining in the washed containers and other objects enter the body directly through the mouth.

On the other hand, in order to clarify the improvement of the safety of the present invention, three types of shampoos will be described by limiting representative types among various experiments. The experiment was 1,00
A 0-fold, 10,000-fold diluted solution and 1,000 times of the composition of the present invention
A 0-fold dilution and a 10,000-fold dilution were used, and a toxicity test was performed based on the survival of the Japanese medaka. Further, in order to make it easier to understand the effects of shampoos on living organisms and the effects of compositions such as Kumasa-basa, the survival status of Medaka per hour with respect to 10,000-fold dilution is shown graphically.

[0013]

FIG.

The selected specimens are three kinds of soap shampoo, complex soap shampoo (whole body shampoo), shampoo containing polyoxyethylene lauryl ether sulfate, and a shampoo to which a composition such as Kumasasa is added. It is.

First, the case where the stock solution of each shampoo is diluted will be described. Among the three, the one with the shortest survival time is
It was a shampoo containing polyoxyethylene lauryl ether sulfate. At 1,000-fold dilution, 5 minutes after 15 minutes
0% lay at the bottom of the aquarium, confirming its death in 18 minutes, and all remaining in 55 minutes. In the case of the 10,000-fold dilution, the animals lay down one by one after 3 hours and lost their energy, and 50% died in 4 hours and 25 minutes, and all the others died in about 7 hours. Next, at 1,000 times the composite soap
Twenty minutes later, 30% sank, and at 55 minutes, everything else died. At 10,000 times the shampoo, the survival rate after one week was 75%. The soap shampoo caused a major change in water before the medaka weakened. It became cloudy over time, and was eventually covered with white fluffy floats. The medaka among them gradually came out above the surface of the water, making it difficult to breathe. And 6 hours 15
Within minutes, 75% died. Everything died in 10 hours. 1
At 000-fold, 20% died after 2 days and 8 hours, and the survival rate after 1 week remained unchanged with the remaining 80% unchanged. From these results, it is judged that the soap shampoo has a considerably longer survival time and less toxicity than the shampoo containing the synthetic surfactant. However, in a highly concentrated soapy water, it is still difficult to say that the living environment is safe. It is considered that the cloudiness of water was generated by the reaction of minerals in the water and organic components discharged from the medaka with the soap component.

On the other hand, the shampoo of the present invention obtained by adding Kumasa and the like to the shampoo has the following changes.
As described in the previous paragraph, the survival of medaka in water to which polyoxylauryl ether sulfate-containing shampoo was dropped was remarkably inferior. Changes occurred after the group died, confirming approximately twice the survival time. In addition, 1
At 0,000-fold, 100% survival occurred 7 hours after the stock solution-diluted group died, and changes began to occur 48 hours later, showing a 70% survival rate even after 168 hours (1 week).

Next, the composition of the composite soap, such as Kumasasa, is
The undiluted solution at 0-fold dilution showed a survival time of 10 times or more as compared to that of the killifish killed within 1 hour, showing that
In the case of the 00-fold dilution, the stock solution group changed after 12 hours, whereas for the nine-fold time, no change was observed and a healthy survival was confirmed.

In the case of soaps as well, compositions such as Kumasasa are:
There was a big difference compared to the stock dilution group. At 1,000-fold dilution, the group of the present invention exhibited a 75% survival rate when the stock solution dilution group survived 25%, and at the time the stock solution dilution group died, 50% survival was confirmed. Is
She was maintained one week later and continued to live well. 10,000
In the 0-fold dilution, 13% died after 2 days in the undiluted solution, whereas the composition such as Kumasasa did not change at all for 1 week.
0% survival was maintained. The above has clarified the effect from the difference between the stock solution dilution group and the present invention based on the shampoo composition.

Further experiments were conducted in order to prove that the composition such as Kumasa-basa did not reduce the toxicity simply by dilution with water, but exhibited a positive effect. In this experiment, shampoo containing polyoxyethylene lauryl ether sulfate, which had the lowest survival rate of medaka, was obtained by diluting a shampoo diluted twice in water to 10,000 times as a control group. The effects of the group and the composition such as Kumasa were compared.

[0020]

FIG. 2

As shown in the figure, the shampoo diluted with water alone died in two and a half days, whereas the survival of the Kumasa basal composition did not change even after one week under this experiment. Was. In addition, the survival rate was improved when 1% salt was added as compared with the control group, but it is presumed that a trace amount of salt works to activate the organism.

[0022]

As is clear from the above description, the surprising effect of Kumasasa component is also maintained by adding it to the shampoo, and the effect on living things or the environment is reduced. It has become more secure.
