Description

The composition of the shampoo rinsing without water}

The present invention relates to a shampoo for the purpose of washing hair, more specifically, it is a shampoo that can be easily cleaned without rinsing with water, especially when used in hospital long-term inpatients, soldiers, fishing, mountaineers, travelers who travel long-term It relates to a shampoo composition having the effect of maintaining the cleanliness of the hair.

Generally, hair is soiled by sweat and various sebum secreted through human metabolism. In addition, due to air pollution, various pollution sources become more dirty.

Conventional shampoo is gel or paste with high viscosity. In the method of use, first, 1) soak the hair in water, 2) soak the shampoo in the hair, 3) rub it, and then foam 4) rinse with water. 5) Dry hair while wiping dry with a dry towel or towel.

In addition, the main ingredient of the existing shampoo is a surfactant consisting of anionic surfactant or amphoteric surfactant having washing power and foaming power, nonionic surfactant, pH adjuster, thickener, preservative, and water solubilizing auxiliary cleaning and fragrance. Recently, the treatment effect has been added, and it contains a moisturizing agent, a conditioning agent, and a hair protection agent together. The proportion of surfactant in the whole shampoo composition comprises 40-50%. These surfactants are non-volatile substances that remain in the hair, causing skin irritation as well as build-up.

This is why the existing shampoo must be thoroughly rinsed with water for this reason. As a conventional shampoo must be rinsed with water, it is difficult to use for hospital long-term inpatients, disabled people, soldiers, fishing, mountaineers, travelers traveling long-term.

Therefore, in recent years, the development of a shampoo for this use class is being made. Korean Patent Nos. 100553321000 and 1008763290000 relate to a shampoo used without water, and both patents use a surfactant as a main component. In this case, a lot of foam is generated in actual use, it takes a lot of time to process the foam after washing, and it takes a lot of time to dry it with a towel, etc. This can lead to the problem that it is much better not to sense the hair.

The present invention is to solve the existing problems as described above having a sufficient cleaning power to remove the sebum and contaminants of the head and also easy to use because only need to wipe off with a dry towel, towel, etc. It can be usefully applied to elderly people, long-term inpatients and critically ill patients, marine sailors, soldiers, or travelers traveling backcountry.

In the present invention, ethanol, methoxy ethanol, and propylene glycol are mixed at the same time without using any surfactant component, thereby providing excellent cleaning effect and drying speed, and also improving the refreshing effect of scalp after use. It is also characterized by providing a shampoo composition that is easy to use and that penetrates deep into the hair and does not rinse with water to make a low aerosol spray formulation.

As described above, the shampoo without water according to the present invention is an aerosol formulation that can be conveniently used without water while having sufficient cleaning power to remove contaminants such as sebum and dust of hair. Since it is not rinsed with water, it can be useful for long-term inpatients, soldiers, fishing, mountaineers, and travelers who travel long-term.

In addition, it is possible to give hair nourishing effect to make hair soft and shiny by using dimethicone copolyol, a silicone oil, as a conditioning agent after hair washing.

In order to achieve the above object, the present invention comprises a shampoo stock solution and a propellant, the shampoo stock solution contains ethanol 30-40%, methoxyethanol 1-5%, propylene glycol 1-3% at the same time The rest provide a rinse without water aerosol spray water.

Hereinafter, the present invention will be described in detail.

The present invention does not use any surfactants widely used in existing shampoo compositions, namely anionic surfactants, amphoteric surfactants, cationic surfactants, and the like, and instead use ethanol, methoxyethanol, and propylene glycol simultaneously. The present invention relates to a shampoo composition which rinses without contaminants such as sebum remaining in the hair and is excellent in cleaning power, as well as no foam after hair washing, and fast drying speed.

Ethanol that can be used in the shampoo composition of the present invention is a modified ethanol, a solvent that can be used in the human body as well as excellent cleaning power, good volatility, and also excellent sterilizing effect is used as a disinfectant.

In the present invention, the ethanol content of 30-40% by weight is less than 30% by weight, the washing power is much lower, and more than 40% of the odor is bad smell is too bad.

In addition, methoxy ethanol that can be used in the shampoo composition of the present invention is an ingredient that can be used in the human body listed in the International Cosmetic Ingredient Dictionary, and has an excellent effect of removing sebum remaining in the hair. It has good volatility, so the drying speed is fast after hair washing.

In the present invention, the methoxyethanol content is less than 1% to 1-5%, the sebum removal ability is much lowered, if more than 5% is excellent washing power, but it is not preferable to decolor the dyed hair.

In addition, propylene glycol that can be used in the shampoo composition of the present invention is widely known as a skin moisturizing agent, but in the present invention is applied as a solvent for removing oily contamination such as sebum, and in addition, in the present invention, propylene glycol also exerts a hair conditioning effect.

If the content of propylene glycol is 1-3% by weight, less than 1%, the oil-polluting ability is removed. If the content is 3% by weight or more, the drying speed is slow, which may cause hair to collect.

In addition, l-menthol which can be used in the shampoo composition of the present invention not only gives a refreshing feeling to the scalp but also prevents hair loss by the blood circulation promoting effect of the scalp, and a more preferable content of l-menthol is 0.5-1.5% by weight, 0.5% by weight Below, the refreshing feeling of the scalp is lowered, and skin irritation may occur at 1.5 wt% or more, and the cost is also increased, which is not preferable.

In the present invention, polyquaternium-7, polyquaternium-10, polyoxyethylene lanolin, lanolin alcohol, methyl polysiloxane, dimethicone copolyol, hydrolyzed animal protein, ethylene glycol monostearic acid, etc. may be used as a conditioning agent after trituration. Preferably it contains 0.5-2.0% of dimethicone copolyol which is a water-soluble silicone oil which makes hair soft and shiny.

Norins shampoo according to the present invention has adopted the aerosol formulation in which the above shampoo solution is put in a metal container and applied with a propellant, which is easy to use and easy to carry as you can adjust the amount of injection as desired by pressing a button. .

The propellant serves to evenly and deeply spray the desired object, that is, the shampoo solution, throughout the hair. Examples of the propellant include isobutane gas, propane gas, dimethyl ether, butane gas, LPG, nitrogen, and compressed air. Among them, isobutane gas, propane gas, butane gas, and ElpG are not easily mixed with water, and thus are difficult to apply to the present invention. Also, nitrogen, compressed air, etc. are not used until the end, and only the stock solution remains. In the present invention, dimethyl ether (Dimethylether) that is well mixed with water was used.

In addition, in the present invention, the optimal weight ratio of 60:40 to 70:30 of the mixed weight ratio of the shampoo solution and the propellant was selected as the aerosol injection formulation. Could achieve the desired quality.

And the selection of the valve system is most important in order to deliver the shampoo stock solution to the hair well and the injection is not interrupted and continuous injection well.

In general, the valve system consists of a combination of valve orifice sizes, more specifically, the valve system consists of a button orifice, a stem orifice, a bay step orifice body orifice, and the shampoo content of the present invention (stock solution + spraying agent) is a small orifice. It is sprayed through. Therefore, the orifice sizes should be adjusted well to obtain the desired injection state, specifically, injection amount (g / sec), injection width, and the like.

The aerosol valve system according to the present invention is optimal when the body orifice diameter is 0.8-1.5mm, the stem orifice diameter is 0.46 -0.70 mm, the vapor step orifice diameter is 0.40mm, and the button orifice diameter is 0.40-0.50mm. The spraying state is shown.

The shampoo composition of the present invention may include preservatives, pH adjusters, fragrances and the like commonly used to maintain basic physical properties and quality as a cleaning composition.

Hereinafter, preferred examples and comparative examples of the present invention are described. The following examples and comparative examples are described for the purpose of more clearly expressing the present invention, but the contents of the present invention are not limited to the following examples and comparative examples.

[Examples 1 to 4 and Comparative Examples 1 to 4]

After adding methoxy ethanol, propylene, fragrance, and phenoxy ethanol to ethanol at a composition ratio as shown in Table 1 below, the mixture was stirred for about 10 minutes, and the remaining water was added thereto, followed by stirring for 20 minutes to prepare a shampoo.

(Table 1)

(Cleaning force test)

In the cleaning power test for the samples prescribed as shown in Table 1, first, the artificial wool pollution of the wool fabric having a structure similar to the hair was washed with the prepared samples to objectify the test. The color difference was compared. In other words, cut the woolen cloth into 5cm × 5cm size and use artificial sebum (Chemical and Physical Behavior of Human Hair, 3rd Edition, p.80, CR Robbins, Springer-Verlag, New York (1994)) and Sudan (III). After contaminated with and washed with water and dried.

The color of the contaminated wool was measured using a color difference meter. Then, put the 5 pieces of woolen to the solution with 50g of the shampoo of Examples 1 to 4 and Comparative Examples 1 to 4, and then washed for 5 minutes and then dried with a towel. The average color value of the dried woolen cloth was measured using a color difference meter. Again, put 5 pieces of wool shampoo in 50g of each shampoo, washed for 5 minutes, then wiped with towel and dried. The dried wool was measured for color using a colorimeter and then averaged.

The above operation was repeated five times to obtain a color difference between the initial color and the color after five treatments, and the results are shown in Table 2.

In Table 2, ΔE is a value obtained by subtracting the color difference measurement of the Wolfo after treatment with each shampoo five times from the color difference measurement of the Wolfo before treatment with the shampoo. Therefore, the larger the value, the better the cleaning power.

Table 2

As shown in the Example of Table 2, it was confirmed that the cleaning power is excellent when it contains ethanol, methoxy ethanol, propylene glycol at the same time and the content shown in the claims.

Consumer Quality Assessment

50 subjects were evaluated by applying the shampoo according to the examples and comparative examples of the above table directly to the hair, and the satisfaction on the cleaning power, scalp refreshing, drying speed. The evaluation criteria were five-point scale, and the average result is shown in (Table 3).

* Evaluation standard *

5 points: Very good, 4 points: Good, 3 points: Normal, 2 points: Bad, 1 point: Very bad

(Injection test)

One of the most important quality of aerosol products, the injection condition test can be divided into injection volume test (g / sec), spray width (cm), and usability test.However, even if the quality of the shampoo solution is excellent, the spraying condition is not satisfactory. It doesn't do its job as a product.

Firstly, the injection amount test should be sprayed with an appropriate amount. Otherwise, if the sprayed amount is too large, it may be uncomfortable to flow out of the hair, and if the sprayed amount is too small, the efficacy may be inferior. The test method uses a stopwatch and measures the weight loss per second at the initial weight in three iterations and makes the average value.

Next, the spray width test should maintain the proper spray width when spraying. If the spray width is too wide, it may get into the eyes. If the spray width is too narrow, it may become concentrated spray and flow down from the hair to contaminate clothes. The test method is measured using a spray pattern tester. (20 cm distance, 0.5 second spray)

Finally, the usability test confirms that the product is sprayed continuously, using the product directly from start to finish, there is no flow from the valve button, and no residual amount remains after the final use.

The test results of Table 4 are shown in Table 5.

*Evaluation standard *
