Description

Cleaning composition {CLEANING COMPOSITION}

The present invention relates to a cleaning composition, and more particularly, to a cleaning composition having less irritation and damage to the hair and improved cleaning power.

When using a detergent, it can be in direct contact with the human body, so it requires a safety tablet for the human body. For example, shampoo should remove foreign substances such as dirt, sebum secretions, dead keratin cells, etc. that remain on the hair, and at the same time, it should not damage the hair and should be less irritating. In other words, the cleaning power should be excellent, but the residual amount of cleaning ingredients that damage and irritate the hair after shampooing should be small.

Surfactant imparts cleaning power to detergents such as shampoos, and anionic surfactants, amphoteric surfactants, nonionic surfactants, and the like are used. Anionic surfactants are surfactants in which the lipophilic part is dissociated into anions by dissolving in water, and is a major component that generates abundant bubbles (bubbles) of the cleaning agent and imparts the cleaning power of the cleaning agent. However, the anionic surfactant has a problem of causing irritation and damage to the hair after washing.

In order to reduce such irritation and damage to the hair, anionic surfactants and amphoteric surfactants are used. Amphoteric surfactants are surfactants whose ionicity varies depending on pH, and have relatively less irritation than anionic surfactants, and provide a conditioning effect that gives gloss by providing flexibility and appropriate oiliness by keeping the hair acidic. However, if the content of the amphoteric surfactant is increased, there is a problem in that the amount of bubbles generated is reduced and the cleaning power is lowered.

On the other hand, nonionic surfactants are composed of fatty alcohols, which are lipophilic groups, and sugars, which are hydrophilic groups, and have low damage and hypoallergenicity to hair, but there is a problem in that the cleaning power is inferior and the hair texture becomes stiff compared to anionic surfactants.

Accordingly, consumers' demand for developing a detergent composition capable of reducing irritation to the human body such as hair at the same time having high cleaning power by using the properties of a surfactant has continued.

Conditioning shampoo composition (Korean Patent Publication No. 10-2012-0019667)

An object of the present invention is to provide a detergent composition having high cleaning power while reducing damage and irritation to hair by controlling the type and mixing ratio of surfactants.

The present invention was devised to solve the above problems, and the detergent composition of the present invention comprises 3 to 7.5% by weight of anionic surfactant and 0.9 to 5% by weight of a sultein-based amphoteric surfactant based on the total weight of the detergent composition. Includes.

Compared to the anionic surfactant, the sultein-based amphoteric surfactant may be contained in the range of 2:1 to 7.5:1. In order to solve the above problems, more preferably, a detergent composition in which the mixing ratio of the sultain-based amphoteric surfactant to the anionic surfactant is in the range of 2:1 to 4:1 may be used. When the mixing ratio of the anionic surfactant to the amphoteric surfactant is 3:1, the foaming power increases by 50.6% and the residual amount of hair increases by 57.7% compared to the case of using only the anionic surfactant. Here, the mixing ratio of 2:1 to 4:1 includes mixing at 2.5:1, 3:1, 3.5:1, and 4:1.

The sultein-based amphoteric surfactant includes lauryl hydroxysultaine. The anionic surfactant includes Sodium Laureth Sulfate.

In the test, the detergent composition containing 5%, 250 ml of an aqueous solution was stirred at 800 rpm for 20 seconds with a foam tester (SITA foam tester R-2000, manufacturer: SITA Messtechnik GmbH), and then carried out twice as one set, the volume of the foam produced. Appears to be 500mL or more, and (b) in the test for measuring the amount of remaining hair, after applying 1g of the detergent composition to a wool swatch, contact with 10g of water for 1 minute and rinse for 30 seconds, 0.5% by weight rubin die (Rubin dye) After immersing in an aqueous solution for 3 minutes, after rinsing in running water for 30 seconds, the color difference control value ( _x a) indicating the degree of color development appears to be 24 or less.

More preferably, when the detergent composition of the present invention contains 6.3 to 6.8% by weight of sodium laureth sulfate as an anionic surfactant and 1.7 to 2.2% by weight of laurylhydroxysulfate as the sultein-based amphoteric surfactant, ( a) In the test for measuring the amount of foam generation, the volume of the foam is 600 mL or more, and (b) in the test for measuring the amount of hair remaining, the color difference control value ( _ㅿ a) is 13 or less.

The detergent composition of the present invention may further contain 1 to 5% by weight of a nonionic surfactant, and further contain 1 to 5% by weight of an additive including a cationic polymer, a chelating agent, a flavoring agent, a preservative, and a thickener. I can.

The detergent composition of the present invention provides an effect of high cleaning power while reducing damage and irritation to hair by controlling the type and mixing ratio of anionic surfactants and amphoteric surfactants.

In particular, when the detergent composition of the present invention contains laurylhydroxysulfane as an amphoteric surfactant, and the mixing ratio of laurylhydroxysulfatein to an anionic surfactant is in the range of 2:1 to 4:1, hair While reducing damage and irritation of the body, the cleaning power can be further improved.

The detailed description of the present invention to be described below will be described in detail so as to be sufficient to enable a person skilled in the art to practice the present invention, and is described with specific embodiments in which the present invention may be practiced. It should be understood that the various embodiments of the present invention are different from each other, but need not be mutually exclusive. Therefore, the detailed description to be described later is not made in a limiting sense, and the scope of the present invention should be taken as encompassing the scope claimed in the claims and all scopes equivalent thereto.

In order to achieve the object described above, the detergent composition of the present invention includes an anionic surfactant and a sultein-based amphoteric surfactant having _{SO 3} ^{-at the terminal.}

Anionic surfactants are dissolved in water of the detergent composition to dissociate the lipophilic part into anions.Sodium laureth sulfate, sodium lauryl sulfate, and ammonium lauryl sulfate sulfate), ammonium laureth sulfate, triethanolamine lauryl sulfate, sodium alpha-olefin sulfonate, isodium laureth sulfosuccinate, Sodium lauroyl sarcosinate (Sodium lauroyl sarcosinate), sodium lauroyl glutamate (sodium lauroyl L-glutamate), triethanolamine cocoyl glutamate (Triethanolamine cocoyl L-glutamate) can be selected from.

Preferably, the anionic surfactant may be sodium lauryl sulfate having 12 carbon atoms in the fatty alcohol group, or sodium laureth sulfate in which ethylene oxide is added to the fatty alcohol group. More preferably, the anionic surfactant may be sodium laureth sulfate or the like. When sodium laureth sulfate is used as the anionic surfactant, since the addition-substituted ethylene oxide of sodium laureth sulfate weakens the action of the sulfuric acid group, the degree of damage and irritation to the hair of sodium laureth sulfate is lower than that of sodium laureth sulfate. Goes low.

The anionic surfactant is contained in an amount of 3 to 7.5% by weight based on the total weight of the detergent composition. Preferably, the anionic surfactant may contain 5.6 to 7% by weight, more preferably 6.3 to 6.8% by weight. If the amount of anionic surfactant exceeds 7.5% by weight, the amount of the anionic surfactant remaining on the hair and scalp is large, causing great irritation, and if it is less than 3% by weight, the foaming power (the degree of foaming) decreases and the cleaning power is weakened.

The amphoteric surfactant is used to reduce the component content of the anionic surfactant contained in the detergent composition of the present invention, supplement the weakened cleaning power, and increase the foaming power related to the cleaning power.

Amphoteric surfactants are cationic or anionic surfactants depending on the pH because they have both anionic and cationic sites.

The amphoteric surfactant usable in the present invention is not particularly limited as long as it has a foaming ability enhancing effect, but for example _{, alkyl betaines having C 8} to C ₂₄ carbon atoms, alkyl sultaines, Alkyl amidopropyl betaines, alkyl amidopropyl hydroxy sultaine, alkyl amphoacetate, alkyl diaamphoacetate, and the like may be used.

In the present invention, among the amphoteric surfactants, a sultein-based amphoteric surfactant having _{SO 3} ^- at the terminal as an anion and an ammonium ion of a cation of the following formula (I) is used.

Here, R is hydrogen, a saturated or unsaturated C ₈ to C ₂₄ alkyl group, a coconut derivative, a C ₁ to C ₅ alkyl group to which the coconut derivative is bonded, an amide group or an amido group substituted C ₈ to C ₂₄ It may be an alkyl group.

The sultein-based amphoteric surfactants include Lauryl Hydroxysultaine, Cocamidopropyl Hydroxysultaine, Coco-Hydroxysultaine, and Erucamidopropyl Hydroxysultaine. Erucamidopropyl Hydroxysultaine, Hydroxysultaines, Lauramidopropyl Hydroxysultaine, Methoxycinnamidopropyl Hydroxysultaine, Myristamidopropyl Hydroxysultaine Myristamidopropyl Hydroxysultaine), Oleamidopropyl Hydroxysultaine and Tallowamidopropyl Hydroxysultaine.

Preferably, among the amphoteric surfactants, laurylhydroxysulfane may be used. When laurylhydroxysulfatein is used as the amphoteric surfactant, the amount of anionic surfactant remaining in the hair is less than when using other amphoteric surfactants, so damage and irritation to the hair can be reduced, and foaming power can be improved. I can make it.

The amphoteric surfactant contains 0.9 to 5% by weight, based on the total weight of the detergent composition. Preferably, the amphoteric surfactant may contain 0.9 to 2.9% by weight, more preferably 1.7 to 2.2% by weight. If the amphoteric surfactant exceeds 5% by weight, the foaming power is lowered and the cleaning power is lowered, and if it is less than 0.9% by weight, the content of the anionic surfactant increases and the residual amount of the anionic surfactant increases, resulting in damage and irritation to the hair. Becomes bigger.

By adjusting the mixing ratio of the anionic surfactant and the amphoteric surfactant, it is possible to simultaneously satisfy irritation and cleaning power. Preferably, if the mixing ratio of the anionic surfactant to the amphoteric surfactant is mixed within the range of 2:1 to 4:1, the amount of residual hair of the anionic surfactant is minimized while maintaining abundant foaming power that affects the cleaning power. I can. For example, when the mixing ratio of the anionic surfactant to the amphoteric surfactant is 3:1, the foaming power is increased by 50.6% and the residual amount of the hair is increased by 57.7% compared to the case of using only the anionic surfactant. The mixing ratio of the anionic surfactant to the amphoteric surfactant is in the range of 2:1 to 4:1, including those mixed at 2.5:1, 3:1, 3.5:1, and 4:1.

If the mixing ratio of the anionic surfactant to the amphoteric surfactant exceeds the 4:1 range and the amount of the anionic surfactant increases, the residual amount of the anionic surfactant significantly increases the irritation, and if it is less than the 2:1 range, the amount of the anionic surfactant increases. It is lowered and the cleaning power is deteriorated.

The detergent composition of the present invention may further include a nonionic surfactant. Nonionic surfactants are composed of fatty alcohols, which are lipophilic groups, and saccharides, which are hydrophilic groups, and may assist in cleaning power that may occur by reducing the content of anionic surfactants and reduce irritation of hair. The nonionic surfactant may be selected from cocamide methyl MEA and cocamide DEA. The nonionic surfactant may be contained in an amount of 1 to 5% by weight based on the total weight of the detergent composition, but is not limited thereto, and preferably 2% by weight.

The detergent composition of the present invention may further include an additive including a cationic polymer, a chelating agent, a flavoring agent, a preservative, and a thickener. The additive is well known in the art as a conventional component for maintaining the basic properties and quality of the detergent composition. For example, by adding a cationic polymer, it is possible to prevent the static electricity of the hair and soften the wet hair, thereby suppressing the cuticle damage caused by friction. As the cationic polymer, Guar Hydroxypropyl trimonium Chloride may be used. In addition, the additives may also include dyes, hair conditioning agents, and viscosity modifiers.

Hereinafter, the detergent composition of the present invention will be described in more detail through examples of the present invention, but the present invention is not limited to these examples.

Raw materials 2 to 3 were added to the raw material 1 at a predetermined ratio to be dispersed, and raw materials 4 to 8 were each sequentially added, stirred and mixed. Subsequently, the raw material 9 was mixed to obtain the detergent compositions of Examples 6 to 10.

<Production Method of Comparative Example>

The comparative examples of Tables 1 and 2 have the same composition and the manufacturing method is also the same as follows.

Raw materials 2 to 3 were added to the raw material 1 at a predetermined ratio to be dispersed, and raw materials 4 and 6 to 8 were sequentially added, respectively, and stirred and mixed. Subsequently, raw material 9 was mixed to obtain a detergent composition of a comparative example.

<Test Example 1> Bubble generating power

In order to compare the foaming force (the degree of foaming) of Examples 1 to 10 and the comparative examples, 250 ml of a 5% aqueous solution of each sample was taken and tested by a foam tester (SITA foam tester R-2000, manufacturer: SITA Messtechnik GmbH). Air bubbles were generated for 20 seconds at 800 rpm using a rotor (proceed in 2 sets). As a result of measuring the volume (mL) of air bubbles generated after stopping the rotor, it appeared as described in Tables 1 and 2.

1 is a graph showing the foaming force of Examples 1 to 10 of the present invention and a comparative example.

<Test Example 2> Hair residual amount

In order to measure the amount of the cationic polymer or cationic polymer-anionic surfactant complex of Examples 1 to 10 and Comparative Examples remaining in the hair, a Rubine Dye Test was performed.

1 g of the compositions of Examples 1 to 10 and Comparative Examples were rubbed on a wool swatch with 10 g of 33° C. water for 1 minute, and then washed with running water for 30 seconds. After washing, a wool swatch was immersed in a 0.5% solution of Rubin Die for 3 minutes to measure the degree of color development using a color difference meter to measure the color difference meter contrast value (ㅿa) indicating the degree to which red color was developed. As described in Tables 1 and 2, the amount of residual hair was shown.

The rubin die is an anionic pigment and is ionic bonded to a cationic polymer or cationic polymer-anionic surfactant complex adsorbed on the hair. Therefore, by analyzing the degree to which the rubin die is dyed with a color difference meter, it is possible to determine the amount of the cationic polymer or the cationic polymer-anionic surfactant complex remaining in the hair. When the degree of dyeing of the rubin die is high, the value of ㅿa, which indicates the degree of red color of the color difference meter indicating the degree of color development, increases, indicating a large amount of residual surfactants that damage hair.

FIG. 2 is an image showing the degree of color development on a wool swatch after the rubin die test of Examples 1 to 10 of the present invention and the comparative example were conducted. 3 is a graph showing the residual amount of hair of the cationic polymer or cationic polymer-anionic surfactant complex of Examples 1 to 10 and Comparative Examples.

As a result of analyzing the experimental results through Test Examples 1 and 2, it can be seen that the foaming power related to the cleaning power was improved in all the Examples compared to the Comparative Example. However, Examples 1 to 3 and 5 showed that the residual amount of hair of the surfactant causing hair damage was higher than that of the comparative example. In Example 4, it was confirmed that the residual amount of hair was slightly lowered and the foaming power was slightly increased compared to the comparative example.

In Examples 6 to 10, compared to the comparative example, while the residual amount of hair of the surfactant was lowered ( _w a 24 or less), the foaming power was higher than 500 mL. In addition, it can be seen that Examples 6 to 10 have high cleaning power while reducing damage and irritation to hair, even when compared to Examples 1 to 5.

Considering the low damage, hypoallergenicity and detergency of hair at the same time, it was found that laurylhydroxysulfatein is preferable as an amphoteric surfactant that can be mixed with an anionic surfactant.

In addition, when the mixing ratio of the anionic surfactant to the amphoteric surfactant is within the range of 2:1 to 4:1 (Examples 8 to 10), the highest while reducing damage or irritation to hair than a detergent composition having a mixing ratio outside the range It was found that the cleaning power appeared. When the mixing ratio of the anionic surfactant to the amphoteric surfactant is less than 2:1, damage and irritation to the hair are reduced, but the cleaning power is poor. On the other hand, when the mixing ratio of the anionic surfactant to the amphoteric surfactant is 4:1 or more, it was confirmed that the cleaning power can be secured, but the damage and irritation of the hair are high.
