本申請案根據美國法典第卅五卷第119條，主張2015年3月31日於韓國智慧財產局提出申請之第10-2015-0045028號及2016年3月21日於韓國智慧財產局提出申請之第10-2016-0033286號韓國專利申請案之優先權，其全文併於此以供參考。 This application is based on Article 119 of Title 5 of the United States Code and claims to be filed at the Korea Intellectual Property Office on March 31, 2015 at the Korea Intellectual Property Office's application No. 10-2015-0045028 and March 21, 2016. The priority of Korean Patent Application No. 10-2016-0033286, the entire disclosure of which is hereby incorporated by reference.
以下揭露係關於一種半永久性的毛髮染料組合物，更具體地，一種包含一酸性染料、一陽離子性聚合物、及一pH值調整劑之半永久性的毛髮染料組合物，因此顯著地減少如下傳統酸性毛髮染料之最大缺點：於皮膚上的染色及染色時間長，並顯示優異的毛髮調理(hair conditioning)感受。 The following disclosure relates to a semi-permanent hair dye composition, more specifically, a semi-permanent hair dye composition comprising an acid dye, a cationic polymer, and a pH adjusting agent, thereby significantly reducing the following tradition The biggest drawback of acid hair dyes: long dyeing and dyeing on the skin, and an excellent hair conditioning experience.
著色劑根據其著色於毛髮上之顏色的耐久性，一般可被分類為永久性、半永久性及暫時性的著色劑。永久性著色劑係為氧化毛髮染料，為了穩定性的原因，其於獨立的容器中分別包含第一劑(為染色劑)及第二劑(為氧化劑)，且在使用前混合第一劑及第二劑。在毛髮染色過程中，由於鹼性劑及氧化劑之作用，產生了毛髮損害之問 題。 Colorants are generally classified as permanent, semi-permanent, and temporary colorants depending on the durability of their color on the hair. The permanent coloring agent is an oxidative hair dye. For stability reasons, the first agent (which is a coloring agent) and the second agent (which is an oxidizing agent) are respectively contained in separate containers, and the first agent is mixed before use and The second dose. In the hair dyeing process, due to the action of alkaline agents and oxidants, hair damage is caused. question.
半永久性著色劑係藉由以一特定顏色著色全部或部分毛髮以改變外貌之一種美容手段，且即使經過多次洗滌後仍可保持其顏色。現今最常見的毛髮用劑係酸性染色劑。 A semi-permanent colorant is a cosmetic means of changing the appearance by coloring all or part of the hair in a specific color, and retains its color even after repeated washings. The most common hair lotion used today is an acid stain.
酸性染料係水溶性染料之一概括的術語，其染料在分子中具有一酸基，且其有1000種或更多的種類，但主要種類為偶氮染料(azo dye)。酸性染料之主要用途為羊毛及人類毛髮之染色，且酸性染料之染色堅牢度(fastness)一般係高於鹼性染料。大部分的染色係使用酸性溶液和檸檬酸、乙醇酸、乳酸及其類似物一起展現，而一般而言，染色在低pH值下良好地完成。即為，當酸性染料溶於水時，其帶負電，且毛髮在該酸性環境之下(pH值2至5)係帶正電，如此酸性染料便藉由離子鍵固定於毛髮上。 An acid dye is one of the water-soluble dyes. The dye has an acid group in the molecule and has 1000 or more species, but the main species is an azo dye. The main use of acid dyes is the dyeing of wool and human hair, and the fastness of acid dyes is generally higher than that of basic dyes. Most of the staining uses an acidic solution to be exhibited together with citric acid, glycolic acid, lactic acid, and the like, and in general, the dyeing is well accomplished at a low pH. That is, when the acid dye is dissolved in water, it is negatively charged, and the hair is positively charged under the acidic environment (pH 2 to 5), so that the acid dye is fixed to the hair by ionic bonding.
一般而言，由於半永久性毛髮染料不同於氧化的永久性毛髮染料(酸性約為pH值2至5)其藉由膨脹毛髮而不造成損害，且由於其不使用阿摩尼亞及過氧化氫，若毛髮已經損害，該毛髮可在不被進一步損害下被染色。 In general, since the semi-permanent hair dye is different from the oxidized permanent hair dye (acidity is about pH 2 to 5), it does not cause damage by expanding the hair, and since it does not use ammonia and hydrogen peroxide If the hair has been damaged, the hair can be dyed without further damage.
韓國專利公開號10-2014-0034593(專利文獻1)揭露一種半永久性的毛髮染料組合物，其包含一酸性染料、多孔性二氧化矽(porous silica)及一水溶性聚合物，因此施加於毛髮後，其具有優異的染料固定強度，在染色後較少的流失，且具有優異的耐久性。 Korean Patent Publication No. 10-2014-0034593 (Patent Document 1) discloses a semi-permanent hair dye composition comprising an acid dye, porous porous silica and a water-soluble polymer, thus being applied to the hair After that, it has excellent dye fixing strength, less loss after dyeing, and excellent durability.
然而，當酸性毛髮染料接觸頭皮或皮膚，染料強力地固定於其上，且因此，一旦酸性染料固定於皮膚上，即便使用還原劑或鹼性劑以移除固定的染料，仍非常難以移除，且由於這樣的缺點，大部分之染料係通常為專業人士於沙龍所使用之產品。進一步地，由於可能不會使用具有優異的毛髮調理感受的陽離子性界面活性劑及聚合物，因而會有不佳的毛髮調理感受的問題。為了防止該酸性染料被固定於皮膚上，日本專利公開號2003-171246(專利文獻2)揭露一種染色材料，其包含一酸性染料、一水溶性聚合物及一有機溶劑。然而，仍有毛髮染料組合物之穩定性變差之問題，因染料於毛髮之固定強度隨著於皮膚上之染料固定之減少而減少，且毛髮調理感受係變差的。 However, when the acid hair dye contacts the scalp or the skin, the dye is strongly fixed thereto, and therefore, once the acid dye is fixed to the skin, it is very difficult to remove even if a reducing agent or an alkaline agent is used to remove the fixed dye. And due to such shortcomings, most of the dyes are usually used by professionals in salons. Further, since cationic surfactants and polymers having excellent hair conditioning feelings may not be used, there is a problem of poor hair conditioning feeling. In order to prevent the acid dye from being fixed to the skin, Japanese Patent Publication No. 2003-171246 (Patent Document 2) discloses a dyeing material comprising an acid dye, a water-soluble polymer and an organic solvent. However, there is still a problem that the stability of the hair dye composition is deteriorated, because the fixing strength of the dye to the hair is reduced as the dye fixation on the skin is reduced, and the hair conditioning feeling is deteriorated.
因此，目前關於一種能降低染料於皮膚上之固定強度但不降低染料於毛髮上之固定強度，且還具有優異的毛髮調理感受之半永久性的毛髮染料組合物之研究係需要的。 Therefore, there is currently a need for a research on a semi-permanent hair dye composition which can reduce the fixing strength of the dye on the skin without reducing the fixing strength of the dye on the hair, and also has excellent hair conditioning experience.

The usable tar acid dye is not particularly limited, and specifically red No. 2, red No. 3, red No. 102, red No. 104, red No. 105, red No. 106, yellow No. 4, yellow No. 5, green No. 3, Blue No. 1, Blue No. 2, Red No. 201, Red No. 227, Red No. 230, Red No. 231, Red No. 232, Orange No. 204, Orange No. 207, Yellow No. 202, Yellow No. 203, Green 201 No., green 204, green 205, blue 202, blue 203, blue 205, red 401, green 402, purple 401, black 401, etc., but are not limited thereto.
為了預期的效果，以該半永久性的毛髮染料組合物之總重量計，可包含0.001至5重量%根據本發明的一例示性實施態樣之酸性染料、較佳地0.01至3重量%。 For the intended effect, from 0.001 to 5% by weight, based on the total weight of the semi-permanent hair dye composition, an acid dye according to an exemplary embodiment of the invention, preferably from 0.01 to 3% by weight.
根據本發明的一例示性實施態樣之陽離子性聚合物，其作為橋樑，使得毛髮與該酸性染料可形成pH值等於或高於等電點之均勻錯合物(complex)，且可被加入以改善染料於毛髮上的固定強度。 A cationic polymer according to an exemplary embodiment of the present invention as a bridge, such that hair and the acid dye can form a uniform complex having a pH equal to or higher than an isoelectric point, and can be added To improve the fixing strength of the dye on the hair.
該陽離子性聚合物可選自由以下所組成之群組之一、或二、或多者：聚季銨鹽-4、聚季銨鹽-6、聚季銨鹽-7、聚季銨鹽-10、聚季銨鹽-11、聚季銨鹽-22、聚季銨鹽-37、聚季銨鹽-39、及聚季銨鹽-100，但不限於此。 The cationic polymer may be selected from one of the following groups, or two or more of: polyquaternium-4, polyquaternium-6, polyquaternium-7, polyquaternium- 10. Polyquaternium-11, polyquaternium-22, polyquaternium-37, polyquaternium-39, and polyquaternium-100, but is not limited thereto.
一般而言，使用半永久性的(酸性)毛髮染料，染色過程可藉由在帶正電毛髮及帶負電酸性染料之間之離子鍵於等於或低於毛髮等電點之pH值下執行，且因此，染色不在高於毛髮等電點之pH值 下完成。 In general, using a semi-permanent (acidic) hair dye, the dyeing process can be performed by the ionic bond between the positively charged hair and the negatively charged acid dye at a pH equal to or lower than the isoelectric point of the hair, and Therefore, the dyeing is not higher than the pH of the isoelectric point of the hair. Finished.
該酸性染料係與本文之陽離子性聚合物一起使用，且因此，本發明具有一技術特徵：即使在等於或高於毛髮等電點之pH值下仍保持染色強度。咸信此特徵係由於該陽離子性聚合物在帶等量負電之毛髮及酸性染料之間，作為輔助其酸性染料於毛髮上之固定之橋樑。 The acid dye is used together with the cationic polymer herein, and therefore, the present invention has a technical feature of maintaining the dyeing strength even at a pH equal to or higher than the isoelectric point of the hair. This characteristic is due to the fact that the cationic polymer acts as a bridge between the hair with an equal amount of negative charge and the acid dye as a means of assisting the fixation of the acid dye on the hair.
以該半永久性的毛髮染料組合物之總重量計，可包含0.5至5重量%根據本發明的一例示性實施態樣之陽離子性聚合物，較佳地1.0至4.0重量%，且更佳地1.5至2.5重量%。若該陽離子性聚合物之含量少於0.5重量%，保持染色強度之效果係不顯著的，而若其含量多於5重量%，該組合物之黏性將因為該聚合物而變得太高，因此不易施加於毛髮上，且相反地，可能產生防止染料固定及使毛髮回潮(dampening)之問題。 The cationic polymer according to an exemplary embodiment of the present invention may be contained in an amount of 0.5 to 5% by weight based on the total weight of the semi-permanent hair dye composition, preferably 1.0 to 4.0% by weight, and more preferably 1.5 to 2.5% by weight. If the content of the cationic polymer is less than 0.5% by weight, the effect of maintaining the dyeing strength is not significant, and if the content is more than 5% by weight, the viscosity of the composition will become too high due to the polymer. Therefore, it is not easy to apply to the hair, and conversely, there may be a problem of preventing dye fixation and dampening the hair.
為了將該半永久性的毛髮染料組合物之pH值保持在4至10，可加入根據本發明的一例示性實施態樣之pH值調整劑，因此改善該組合物之穩定性，且輔助毛髮與酸性染料間之陽離子性聚合物錯合物之形成。 In order to maintain the pH of the semi-permanent hair dye composition at 4 to 10, a pH adjusting agent according to an exemplary embodiment of the present invention may be added, thereby improving the stability of the composition and assisting hair and Formation of a cationic polymer complex between acid dyes.
根據本發明的一例示性實施態樣，該pH值調整劑並未限制，只要其為弱鹼之有機酸鹼金屬鹽，且該金屬鹽可為鈉鹽、鉀鹽或其類似物，最佳地為鈉鹽。於本文之該有機酸鹼金屬鹽可選自由以下所組成之群組之一、或二、或多者：如乳酸鈉及檸檬酸鈉之弱鹼性成 分，對於組合物之穩定性的改善及pH值的調整，較佳地使用檸檬酸鈉係有效的。 According to an exemplary embodiment of the present invention, the pH adjusting agent is not limited as long as it is a weak base organic acid alkali metal salt, and the metal salt may be a sodium salt, a potassium salt or the like, preferably The ground is sodium salt. The organic acid alkali metal salt herein may be selected from one of the following groups, or two or more of them: weakly alkaline such as sodium lactate and sodium citrate The improvement of the stability of the composition and the adjustment of the pH are preferably carried out using sodium citrate.
根據本發明的一例示性實施態樣，該pH值調整劑可為有機酸鹼金屬鹽(為弱鹼)及有機酸(為弱酸)於1.5至5：1(較佳地1.5至4：1，及更佳地1.5至2.5：1)之重量比之混合物，且該金屬鹽可為鈉鹽、鉀鹽或其類似物，最佳地為鈉鹽。於本文，該有機酸鹼金屬鹽可選自由以下所組成之群組之一、或二者：乳酸鈉及檸檬酸鈉；及該有機酸可選自由以下所組成之群組之一、或二者：乳酸及檸檬酸(為弱酸)。透過如此，染色性質可被改善，且染料於皮膚上之固定特質可被調整為低，且特別地，較佳的使用乳酸作為該有機酸，因為染色特性係大幅地改善。 According to an exemplary embodiment of the present invention, the pH adjusting agent may be an organic acid alkali metal salt (which is a weak base) and an organic acid (which is a weak acid) at 1.5 to 5:1 (preferably 1.5 to 4:1). And, more preferably, a mixture of weight ratios of 1.5 to 2.5:1), and the metal salt may be a sodium salt, a potassium salt or the like, most preferably a sodium salt. Herein, the organic acid alkali metal salt may be selected from one of the following groups, or both: sodium lactate and sodium citrate; and the organic acid may be selected from one of the following groups, or both : lactic acid and citric acid (as weak acid). By this, the dyeing property can be improved, and the fixing property of the dye on the skin can be adjusted to be low, and in particular, lactic acid is preferably used as the organic acid because the dyeing property is greatly improved.
本文之該pH值調整劑及該陽離子性聚合物係不特別地限制，但可以0.8至2.0：1之重量比混合，較佳地為0.8至1.7：1，而更佳地為0.8至1.4：1，且如果該重量比低於上述之範圍，染料於皮膚上之固定之情況會因為該組合物之穩定性之降低以及濕潤調配物(damp formulation)之使用而增加，且如果該重量比高於上述之範圍，染色過程無法良好地完成，且因此，為了改善染色效果且不造成染料於皮膚上之固定，較佳的使用上述範圍之重量比。 The pH adjusting agent and the cationic polymer herein are not particularly limited, but may be mixed in a weight ratio of 0.8 to 2.0:1, preferably 0.8 to 1.7:1, and more preferably 0.8 to 1.4: 1, and if the weight ratio is less than the above range, the fixation of the dye on the skin may increase due to a decrease in the stability of the composition and the use of a damp formulation, and if the weight ratio is high, Within the above range, the dyeing process cannot be satisfactorily completed, and therefore, in order to improve the dyeing effect without causing the dye to be fixed on the skin, it is preferred to use the weight ratio of the above range.
根據本發明的一例示性實施態樣，為了改善染料於毛髮上之固定強度，該半永久性的毛髮染料組合物可進一步包含選自由以 下所組成之群組之一、或二、或多者：芳香族有機溶劑、(C1-C5)低級醇、聚合物溶劑及純化水。 According to an exemplary embodiment of the present invention, in order to improve the fixing strength of the dye on the hair, the semi-permanent hair dye composition may further comprise one or two or more selected from the group consisting of: An aromatic organic solvent, a (C 1 -C 5 ) lower alcohol, a polymer solvent, and purified water.
該芳香族有機溶劑，只要其在該技術領域係明顯地熟知，可為任何芳香族有機溶劑，但較佳的使用苯甲醇。 The aromatic organic solvent may be any aromatic organic solvent as long as it is well known in the art, but benzyl alcohol is preferably used.
以該半永久性的毛髮染料組合物之總重量計，可包含1.0至10重量%根據本發明的一例示性實施態樣之該芳香族有機溶劑，較佳地為2.0至7.0重量%。 The aromatic organic solvent according to an exemplary embodiment of the present invention may be contained in an amount of from 1.0 to 10% by weight based on the total weight of the semi-permanent hair dye composition, preferably from 2.0 to 7.0% by weight.
若該芳香族有機溶劑之含量少於1.0重量%，染料固定強度之改善效果係不顯著的，而若其含量多於10重量%，則不容易保持該組合物之穩定性，因該芳香族有機溶劑可能自該組合物分離。 If the content of the aromatic organic solvent is less than 1.0% by weight, the effect of improving the fixing strength of the dye is not remarkable, and if the content is more than 10% by weight, the stability of the composition is not easily maintained because of the aromaticity. The organic solvent may be separated from the composition.

〔實施例1至20，及比較例1至10〕 [Examples 1 to 20, and Comparative Examples 1 to 10]
實施例1至20及比較例1至10之組合物係用下表1之組成 所製備，且測量其物理性質並顯示於下表2(單位：重量%) The compositions of Examples 1 to 20 and Comparative Examples 1 to 10 were composed of the following Table 1. Prepared and measured for physical properties and shown in Table 2 below (unit: % by weight)
如上表2顯示，根據本發明之實施例1至20之該組合物之pH值係在4至10之範圍內，且染色性質係優異的，且染料於皮膚上之 固定之性質係低的。 As shown in Table 2 above, the pH of the composition according to Examples 1 to 20 of the present invention is in the range of 4 to 10, and the dyeing property is excellent, and the dye is on the skin. The nature of fixation is low.
相反地，可看出比較例1之染色強度與本發明之強度係相似的(相似於傳統酸性毛髮染料之情況下)，但染料於皮膚上之固定係嚴重的。 On the contrary, it can be seen that the dyeing strength of Comparative Example 1 is similar to that of the present invention (similar to the case of the conventional acid hair dye), but the fixing of the dye on the skin is severe.
比較例2包含陽離子性聚合物，但僅使用乳酸做為pH值調整劑，表示該組合物之pH值為4或更低，且因此，顯示降低的染色強度，且也藉由降低的染色強度使染料於皮膚上之固定降低。 Comparative Example 2 contains a cationic polymer, but only lactic acid is used as a pH adjuster, indicating that the composition has a pH of 4 or lower, and thus, exhibits reduced dyeing strength, and also by reduced dyeing strength. The fixation of the dye to the skin is reduced.
進一步地，比較例3(包含本發明特定的pH值調整劑，但不包含陽離子性聚合物)之染色性質係快速地降低的。在比較例4至6也包含極少量之陽離子性聚合物，和比較例3一樣，比較例4至6幾乎不產生染色，且染料於皮膚上之固定係稀少的。 Further, the dyeing properties of Comparative Example 3 (containing the specific pH adjuster of the present invention, but not including the cationic polymer) were rapidly lowered. In Comparative Examples 4 to 6, a very small amount of the cationic polymer was also contained, and as in Comparative Example 3, Comparative Examples 4 to 6 hardly produced dyeing, and the fixing of the dye on the skin was scarce.
進一步地，比較例7及8包含過量的陽離子性聚合物，染色強度甚至降低了50%，但相反地，由於該組合物之減少的穩定性及濕潤調配物，染料於皮膚上之固定係增加的。 Further, Comparative Examples 7 and 8 contain an excess of cationic polymer, and the dyeing strength is even reduced by 50%, but conversely, due to the reduced stability of the composition and the wet formulation, the fixing of the dye to the skin is increased. of.
進一步地，比較例9不包含具有快速地降低的染色性質之陽離子性聚合物，且使用檸檬酸鈉及乳酸之間0.5：1之比例(低於1.5至5：1)做為該pH值調整劑之組成比，且因此，該組合物之pH值為4或更低。因此，顯示變差的染色強度，及基於該降低的染色強度因而降低染料於皮膚上之固定。 Further, Comparative Example 9 does not contain a cationic polymer having rapidly lowered dyeing properties, and uses a ratio of 0.5:1 (less than 1.5 to 5:1) between sodium citrate and lactic acid as the pH adjustment. The composition ratio of the agent, and therefore, the pH of the composition is 4 or lower. Therefore, the deteriorated dyeing intensity is displayed, and the dyeing strength is lowered on the skin based on the reduced dyeing strength.
進一步地，在比較例10中，使用檸檬酸鈉及乳酸之間 0.5：1之比例(低於1.5至5：1)做為該pH值調整劑之組成比，且因此，該組合物之pH值為4或更低。因此，顯示變差的染色強度，及基於該降低的染色強度因而降低染料於皮膚上之固定。 Further, in Comparative Example 10, between sodium citrate and lactic acid was used. A ratio of 0.5:1 (less than 1.5 to 5:1) is used as the composition ratio of the pH adjuster, and therefore, the composition has a pH of 4 or lower. Therefore, the deteriorated dyeing intensity is displayed, and the dyeing strength is lowered on the skin based on the reduced dyeing strength.
根據本發明，由於染色係以陽離子性聚合物做為毛髮與酸性染料之間之橋樑的方式完成，該半永久性的毛髮染料組合物具有優異的染料於毛髮上之固定強度，且同時地，具有優異的毛髮調理感受，其僅花費與使用毛髮處理花費的時間相近的短暫的停留時間。 According to the present invention, since the dyeing is carried out by using a cationic polymer as a bridge between the hair and the acid dye, the semi-permanent hair dye composition has excellent fixing strength of the dye on the hair, and at the same time, Excellent hair conditioning experience, which only takes a short residence time similar to the time it takes to use hair treatment.
此外，可提供較少的染料於皮膚上之固定及易於移除固定於皮膚上之染料之效果。 In addition, it provides less dye on the skin and facilitates the removal of dyes immobilized on the skin.
以上，描述了本發明較佳的例示性實施態樣，然而，在本發明中可使用各種修改及等效物，且上述實施例可被適當地修改及相同的施用。因此，上方之描述係不受限於藉由所附申請專利範圍所界定之本發明之範疇。 The preferred embodiments of the present invention have been described above, however, various modifications and equivalents may be used in the present invention, and the above embodiments may be appropriately modified and applied the same.
