Description

COMPOSITION FOR THE OXIDATIVE DYEING CONTAINING NATURAL MATERIALS
The present invention relates to a composition for oxidative dyeing of keratin fibers, more particularly to a composition for oxidative dyeing of keratin fibers containing one or more natural material(s) selected from green tea polysaccharide, cypress polysaccharide, herbaceous peony, lotus root, Eclipta prostrata, Bletilla striata, Sophora flavescens and Coptis chinensis.
In the modern society, men and women of all ages dye their hair to conceal gray hairs or to express their individualities. However, some people are allergic to the oxidative hairdyes and suffer from swollen skin or festering scalp. In addition, those who have sensitive scalps may suffer from scalp irritation, itching or inflammation.
The hairdyes are categorized into permanent hairdye, semipermanent hairdye, temporary hairdyes and other hairdyes depending on how long the color persists.
The permanent hairdye is generally an oxidative hairdye , which color is produced by an oxidation reaction of an oxidative dye. The semipermanent hairdye uses a non-oxidative, acidic or basic dye to dye hair.
And, the temporary hairdye gives temporary coloring effect by adhering pigments, pearls, or the like to hair surface using a film-forming agent. Other hairdyes include those using natural plant dyes such as henna, indigo, chamomile, etc., metallic hairdyes which dye hair through oxidation with silver nitrate or lead acetate, or the like.
In general, an oxidative hairdye contains a first agent(dye phase) and a second agent(Developer). When the two agents are mixed, the dyes included in the first agent produce color as they are oxidatively polymerized. And, hydrogen peroxide in the second agent decomposes the melanin in hair and lightens the background hair color, so that a more distinct color may be produced.
The oxidative dyes may enter the cortex layer of hair because they have a small size. However, when they are polymerized by oxidation, it is difficult for them to penetrate into the hair. As such, if the oxidative dye is polymerized before penetrating into hair, the hair is not dyed well or the dyed hair does not sustain the color for a long time.
Further, the alkaline agent and hydrogen peroxide may irritate the scalp or skin and may damage the protein in hair. If the amount of the alkaline agent is increased to produce a brighter color, the irritation and hair damage also increase. And, increasing the amount of ammonia(alkaline agent) may result in offensive odor.
Often, an acidic dye or a temporary dye is used to avoid the problems associated with the oxidative dye. However, the dyeing performance is lower than the permanent hairdye. In addition, such dyes do not completely solve the irritation problem.
Accordingly, there is a need for developing a composition capable of reducing irritations of a hairdye by using ingredients having antiinflammatory and skin irritation alleviating effects, in order to reduce irritations and inflammations on the scalp and reduce adverse effects of the use of the hairdye.
In order to solve the aforementioned problems, the inventors of the present invention have searched for natural materials capable of alleviating irritation to the scalp and improving dyeing performance and color persistence by controlling reactivity with a dye to facilitate penetration into hair. As a result, they have found out that the use of one or more natural material(s) selected from green tea polysaccharide, cypress polysaccharide, herbaceous peony, lotus root, Eclipta prostrata, Bletilla striata, Sophora flavescens and Coptis chinensis reduces adverse effects of a hairdye, improves dyeing performance and color persistence, and alleviates damage of hair.
Accordingly, an object of the present invention is to provide a composition for oxidative dyeing containing natural materials capable of alleviating skin irritation and inflammation caused by hair dyeing, improving dyeing performance and color persistence and alleviating hair damage, and an additive mixture for oxidative dyeing containing the natural materials.
Another object of the present invention is to provide a dyeing method capable of improving dyeing performance and color persistence by enhancing dyeing property of hair using a hairdye composition containing the natural materials and alleviating hair damage.
To achieve the object of the present invention, the present invention provides a composition for oxidative dyeing of keratin fibers and an additive mixture for oxidative dyeing containing one or more selected from green tea polysaccharide, cypress polysaccharide, herbaceous peony, lotus root, Eclipta prostrata, Bletilla striata, Sophora flavescens and Coptis chinensis.
A hairdye for oxidative dyeing according to the present invention contains one or more natural material(s) selected from green tea polysaccharide, cypress polysaccharide, herbaceous peony, lotus root, Eclipta prostrata, Bletilla striata, Sophora flavescens and Coptis chinensis.

The present invention provides a composition for oxidative dyeing of keratin fibers comprising an oxidative dye precursor, a coupler, an alkaline agent, an antioxidant, an oxidizing agent and a reducing agent, which comprises one or more natural material(s) selected from green tea polysaccharide, cypress polysaccharide, herbaceous peony, lotus root, Eclipta prostrata, Bletilla striata, Sophora flavescens and Coptis chinensis as an effective ingredient.
More specifically, the present invention provides a composition for oxidative dyeing of keratin fibers, comprising an oxidative dye precursor, a coupler, an alkaline agent, an antioxidant, a reducing agent, etc. as a first agent and an oxidizing agent such as hydrogen peroxide as a second agent, or comprising only the first agent, wherein one or more selected from green tea polysaccharide, cypress polysaccharide, herbaceous peony, lotus root, Eclipta prostrata, Bletilla striata, Sophora flavescens and Coptis chinensis is used.
Further, the present invention provides an additive mixture for oxidative dyeing comprising one or more selected from green tea polysaccharide, cypress polysaccharide, herbaceous peony, lotus root, Eclipta prostrata, Bletilla striata, Sophora flavescens and Coptis chinensis, which is mixed with the oxidative hairdye immediately before use to improve dyeing property of hair, thereby improving color development and persistence.
The composition and the additive mixture for oxidative dyeing according to the present invention prevent and alleviate irritations or inflammations of the scalp caused by hair dyeing.
Each of the green tea polysaccharide, cypress polysaccharide, herbaceous peony, lotus root, Eclipta prostrata, Bletilla striata, Sophora flavescens and Coptis chinensis is included in the hairdye in the form of powder, extract or concentrate, and is prepared as follows.
Green tea polysaccharide is prepared by removing chlorophyll and low-molecular-weight polyphenols from pulverized green tea powder by solvent extraction, obtaining green tea polysaccharide extract by hot water extraction, concentrating the extract under reduced pressure, removing low-molecular-weight free proteins by ultrafiltration, precipitating green tea polysaccharide, and drying the precipitate in vacuum to obtain green tea polysaccharide in powder form. Cypress polysaccharide is prepared by extracting dried cypress leaves by adding water, concentrating the extract under reduced pressure, removing low-molecular-weight free proteins by ultrafiltration, precipitating cypress polysaccharide, and drying the precipitate in vacuum to obtain cypress polysaccharide in powder form.
Herbaceous peony(Paeonia lactiflora) belongs to the family Paeoniaceae and has been grown longer than tree peony. In Oriental medicine, the root of herbaceous peony is used after washing and drying, or immersing in boiling water and drying. Especially, the root of herbaceous peony is called red peony and the root of herbaceous peony with the skin peeled off is called white peony. In the present invention, dried herbaceous peony is used after pulverization. But, it may also be extracted using water, organic solvent, or a mixture of water and organic solvent.
Lotus root refers to the root of lotus, a perennial aquatic plant in the family Nymphaeceae. In the present invention, lotus root powder prepared by pulverizing dried lotus root to an average particle size of 36 to 39 ㎛ may be used. Although the particle size of 36 to 39 ㎛ is selected considering the easiness of mixing with the hairdye, the scope of the present invention is not limited thereto. That is to say, the particle size may be larger or smaller. Further, lotus root extract prepared by extracting the lotus root with water or organic solvent, or lotus root concentrate prepared by concentrating the lotus root extract may be used. The organic solvent may be one or more selected from a group consisting of ethanol, methanol, butanol, ether, ethyl acetate and chloroform. Also, mixtures of these organic solvent with water may be used.
Eclipta prostrata is an annual herbaceous plant belonging to the family Asteraceae. It is 10 to 70 cm tall. The whole plant contains saponin, nicotine, tannin, vitamin A, ecliptine, varoius triphene compounds( -terthienyl methanol and acetate ester thereof), and the coumarin compound wedelolactone. Its leaf contains wedelolactone and demethylwedelolactone-7-glucoside. In the present invention, Eclipta prostrata is used after drying well and pulverizing. But, it may also be extracted using water, organic solvent, or a mixture of water and organic solvent.
Bletilla striata grows on sunny place and is planted for ornamental purposes. In Oriental medicine, its tuber, called bletillae tuber is used to treat wounds, gastric ulcer, or the like, as astringent, styptic or pus drainer. In China, it is used to treat heartburn, cough and dyspnea. Also, it is made into glue because it has slimy property.
In the present invention, Bletilla striata may be used after being boiled, steamed, roasted, broiled or heated. More specifically, Bletilla striata may be boiled at 60 to 100℃ for 30 minutes to 2 hours, steamed at 120 to 150℃ for 3 to 6 hours, roasted at 100 to 180℃ for 10 minutes to 1 hour, or broiled at 80 to 100℃ for 10 minutes to 1 hour. Thus obtained Bletilla striata is extracted under reflux after adding water or organic solvent. After sedimentation, followed by filtration and centrifuge to separate the residual from the filtrate, the resultant filtrate is concentrated under reduced pressure to obtain Bletilla striata extract. The organic solvent may be selected from a group consisting of ethanol, methanol, butanol, ether, ethyl acetate, chloroform and mixtures of these organic solvents with water. Preferably, 80% ethanol may be used.
Sophora flavescens is referred to in China as kushen(which literally means bitter root) because of its bitter taste. It has a characteristic persistent odor and very bitter and cold properties. It is used to treat dysentery, leucorrhea, pruritis vulvae, itching skin, or the like. It is also used when urination is difficult and painful due to cystitis. It is reported that it has such pharmacological effects as leucopenia treating, anti-radioactive, coronary blood flow increasing, heart muscle strengthening, blood glucose lowering, anti-tumor, antibacterial and immune suppressing effects.
In the present invention, Sophora flavescens extract prepared in the same manner as the preparation of Bletilla striata extract is used.
In Oriental medicine, the root of Coptis chinensis is harvested in November and dried under sunlight to be used to treat indigestion, gastritis, enteritis, stomachache, nausea, dysentery, palpitation, fever, dysphoria, sore throat, hematemesis, nosebleed, bloody discharge, burn, etc. because it has stomach strengthening, tranquilizing, anti-inflammation and antibacterial effects.
In the present invention, Coptis chinensis extract prepared in the same manner as the preparation of Bletilla striata extract is used.
Thus prepared one or more natural material(s) selected from green tea polysaccharide, cypress polysaccharide, herbaceous peony, lotus root, Eclipta prostrata, Bletilla striata, Sophora flavescens and Coptis chinensis is included in an amount of 0.01 to 30 wt%, preferably 0.1 to 10 wt%, based on the total weight of the hairdye composition.
If the natural material is included in an amount less than 0.01 wt%, the effect of improving dyeing performance and color persistence or alleviating hair damage and scalp irritation may not be attained. And, if it is included in an amount exceeding 30 wt%, coloring may be insufficient because oxidative polymerization of dye may be suppressed.
A hairdye for oxidative dyeing according to the present invention may be a 1-formulation type comprising a mixture of a hairdye as a first agent and a developer as a second agent, or a 2-formulation type including a hairdye as a first agent and a developer as a second agent, which are separately packaged.
The hairdye may be one or more selected from a group consisting of: an acidic hairdye comprising an acidic dye and a direct dye; a semipermanent hairdye comprising a basic dye; a metallic hairdye comprising silver nitrate and lead acetate; a mordant hairdye comprising iron sulfate and aluminum compound along with pyrogallol, hematein or gallic acid; and a natural hairdye comprising a natural dye such as henna, indigo and chamomile.
The composition for oxidative dyeing according to the present invention may further comprise an additive mixture comprising one or natural material(s) selected from green tea polysaccharide, cypress polysaccharide, herbaceous peony, lotus root, Eclipta prostrata, Bletilla striata, Sophora flavescens and Coptis chinensis as a third agent. The natural material may be included in an amount of 0.01 to 100 wt%, based on the total weight of the additive mixture.
The additive mixture is used in an amount of 0.01 to 30 wt%, preferably 0.1 to 5 wt%, based on the total weight of the hairdye. If it is used in an amount less than 0.01 wt%, the effect of protecting scalp and skin may not be attained. And, if it is used in an amount exceeding 30 wt%, coloring may be insufficient because oxidative polymerization of dye may be suppressed.
For example, when a commercially available oxidative permanent hairdye is used, the additive mixture according to the present invention may be added when the first agent and the second agent are mixed. In addition, it may be mixed with any bleaching agent, including a cream-type bleach, a lotion-type bleach and a powder-type bleach comprising potassium persulfate and ammonium persulfate.
The third agent according to the present invention, i.e. the additive mixture, provides an excellent effect of protecting scalp and skin from itching, irritation, inflammation and erythema during hair dyeing.
The composition for oxidative dyeing according to the present invention may be used in a neutral to alkaline pH range of pH 6 to 12, preferably in an alkaline pH range of pH 8 to 11. If the pH is below 6, the oxidizing agent included in the second agent may not be decomposed well, so that it may not effectively penetrate into hair. And, a pH above 12 may result in damage of proteins in hair or skin irritation.
The alkaline agent may be an alkaline agent commonly used in a hairdye, such as ammonia, monoethanolamine, aminomethylpropanol, ispropanolamine, sodium hydroxide, potassium hydroxide, etc.

The additive mixtures of Examples 10 to 18 were added in an amount of 1 g when 60 g of the composition of Comparative Example 1 was mixed with 60 g of the second agent(developer).
After hair dyeing, the panels were asked to evaluate the improvement of irritation from 1 to 5 points, with 0.5 point intervals. They were asked to give 1 point when they felt little improvement in irritation(the same irritation as existing hairdye) and to give 5 points when they experienced distinct improvement in irritation of the scalp. The result is given in Table 5.
Figure PCTKR2009007044-appb-I000006
As seen in Table 4 and Table 5, the control group and Group J, who were subjected to hair dyeing only with the composition of Comparative Example 1 and the second agent(developer), without using green tea polysaccharide, cypress polysaccharide, herbaceous peony, lotus root, Eclipta prostrata, Bletilla striata, Sophora flavescens or Coptis chinensis, felt irritations the same as existing hairdyes. Of the panels who had been suffering from irritations during hair dyeing, those who used the compositions of Examples 1 to 9 and those in the Groups A, B, C, D, E, F, G, H and I experienced improved irritations over existing hairdyes. Therefore, it was confirmed that the compositions comprising the natural materials according to the present invention are effective in relieving scalp irritations caused by hair dyeing.
Test Example 2: Evaluation of dyeing performance
(1) Evaluation of uptake of hairdye compositions of Examples 1 to 9 and Comparative Example 1
In order to evaluate the uptake of the hairdye compositions of Examples 1 to 9 and Comparative Example 1, the first agent hairdye compositions of Examples 1 to 9 and Comparative Example 1(Table 1) and the second agent(developer) composition(Table 2) were mixed at a ratio of 1 : 1 and evenly applied to 12 cm-long human hair such that the amount of the mixture was 2 times the weight of the hair. The hair included about 30% of gray hair. Then, after waiting for 30 minutes, the dyed hair was cleaned for 1 minute with flowing water, using a shampoo, and then dried using a hair dryer. The color of the dried hair was measured using a colorimeter(Hunterlab Labscan XE). The result was compared with the brightness value L* measured with the colorimeter. A higher L* value means a thinner color, and a smaller value means a stronger color. Accordingly, a smaller L* value indicates a better dyeing performance.
Figure PCTKR2009007044-appb-I000007
As seen in Table 6, all of Examples 1 to 9, in which one or more natural material(s) selected from green tea polysaccharide, cypress polysaccharide, herbaceous peony, lotus root, Eclipta prostrata, Bletilla striata, Sophora flavescens and Coptis chinensis were included, showed better dyeing performance than Comparative Example 1 because of higher affinity for hair.
(2) Evaluation of uptake of hairdye compositions of Examples 10 to 18 and Comparative Example 1
In order to evaluate the uptake of the hairdye compositions of Examples 10 to 18, 1 g of the composition of Examples 10 to 18 was added when 60 g of the first agent hairdye composition of Comparative Example 1 was mixed with 60 g of the second agent (developer) composition(Table 2). The mixture was evenly applied to 12 cm-long human hair such that the amount of the mixture was 2 times the weight of the hair. The hair included about 30% of gray hair.
Then, after waiting for 30 minutes, the dyed hair was cleaned for 1 minute with flowing water, using a shampoo, and then dried using a hair dryer. The color of the dried hair was measured using a colorimeter(Hunterlab Labscan XE). The result was compared with the brightness value L* measured with the colorimeter. A higher L* value means a thinner color, and a smaller value means a stronger color. Accordingly, a smaller L* value indicates a better dyeing performance.

As seen in Table 7, all of Examples 10 to 18, in which one or more natural material(s) selected from green tea polysaccharide, cypress polysaccharide, herbaceous peony, lotus root, Eclipta prostrata, Bletilla striata, Sophora flavescens and Coptis chinensis were added to the first agent hairdye composition of Comparative Example 1 and the second agent (developer) composition of Table 2, showed better dyeing performance than Comparative Example 1 because of higher affinity for hair.
Test Example 3: Evaluation of color persistence
(3) Evaluation of color persistence of hairdye compositions of Examples 1 to 18 and Comparative Example 1
The hair dyed in Test Example 2 was immersed in a shampoo solution, shaken at 200 rpm for 30 minutes using a shaker, rinsed with flowing water for 1 minute, and dried using a hair dryer. Then, L* value was measured using a colorimeter. Color persistence was evaluated from the difference ㅿL* of brightness with the values given in Tables 6 and 7. A smaller ㅿL* value means a better color persistence. The result is given in Table 8.
Figure PCTKR2009007044-appb-I000009
As seen in Table 8, when one or more natural material(s) selected from green tea polysaccharide, cypress polysaccharide, herbaceous peony, lotus root, Eclipta prostrata, Bletilla striata, Sophora flavescens and Coptis chinensis was added to the oxidative hairdye or the additive mixture, discoloring of dyed hair was prevented and superior color persistence was attained.
Test Example 4: Evaluation of hair damage
In order to evaluate hair damage, a panel of five experts was asked to evaluate damage of the hair dyed in Test Example 2 according to the following standard. The result is given in Table 9.
Figure PCTKR2009007044-appb-I000010
As seen in Table 9, all of Examples 1 to 18, in which one or more natural material(s) selected from green tea polysaccharide, cypress polysaccharide, herbaceous peony, lotus root, Eclipta prostrata, Bletilla striata, Sophora flavescens and Coptis chinensis was added to the hairdye or additive mixture, showed better hair protecting effect than Comparative Example 1.
