Description

[Technical Field]

[0001] The present invention relates to an oxidation hair dye or bleaching agent, and more particularly to an oxidation hair dye or bleaching agent that can impart moisturizing, gloss, and elasticity and strength to hair after drying. [Background technology]

[0002] In recent years, various hair coloring agents have been developed, making it possible to easily enjoy coloring hair.

[0003] There are various types of hair coloring agents, including oxidative hair dyes, acidic hair dyes, bleaches, and temporary colorants, and they are used according to the needs of each. Among them, oxidative hair dyes or bleaches are mainly used by mixing a first agent containing one or more of either an alkaline agent or an oxidative dye with a second agent containing an oxidizing agent, and are the hair coloring agents currently used by many people.

[0004] However, because oxidative hair dyes or bleaches contain alkaline or oxidizing agents, they are known to damage hair when used on the hair, and to reduce the feel of hair, particularly in terms of its moisturizing, shine, firmness, and body, after drying. For this reason, various studies have been conducted to improve the feel of oxidative hair dyes or bleaches.

[0005] Patent Document 1 discloses that by incorporating royal jelly, peptides, and seaweed extract into a hair dye composition, good results were obtained in terms of moisturizing, smoothness, and shine of hair after drying.

[0006] Patent Document 2 discloses that by including a quaternary ammonium cationic surfactant and an anionic surfactant that is an alkyl sulfate or its salt in an optional ratio in an alkali-containing first agent, good results were obtained in terms of moist, smooth, and shiny feel on hair after drying.

[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-63301 [Patent Document 2] Japanese Patent Application Publication No. 2017-226637 Summary of the Invention [Problem to be solved by the invention]

[0008] However, Patent Documents 1 and 2 do not consider the bounce and body of hair after drying, and since they do not simultaneously satisfy the moist feeling, luster, bounce and body of hair after drying, there is room for further study.

[0009] Therefore, an object of the present invention is to provide an oxidative hair dye or bleach that can impart moist feeling, shine, bounce and strength to hair after drying. [Means for solving the problem]

[0010] The present inventors have discovered that an oxidative hair dye or bleach, which is prepared by mixing a first agent containing one or more of an alkaline agent or an oxidative dye and a second agent containing an oxidizing agent before use, and which is characterized by containing (A) 0.000015 to 3 mass% of one or more selected from avocado oil or vegetable squalane, (B) 0.000015 to 3 mass% of one or more selected from camellia oil, shea butter, and rosehip oil, and (C) 0.000015 to 3 mass% of one or more selected from jojoba oil or (hydrolyzed silk / PG propylmethylsilanediol) crosspolymer, can impart moisturizing, shine, bounce, and strength to hair after drying, and have completed the present invention.

[0049] The present invention will be described in more detail below with reference to examples, but these examples are not intended to limit the present invention in any way.

[0050] The evaluation tests shown in this specification were carried out by varying the components and their contents in the first or second agent. The units used to indicate the contents of each component are all mass% and these were prepared using standard methods. Note that "EO" in parentheses indicates ethylene oxide, and the numbers indicate the number of moles of ethylene oxide added. The mixing ratio in the evaluation tests shown in this specification indicates the ratio at which the first and second agents are mixed.

[0051] In the evaluation tests described herein, a black hair tress (human black hair, Bealux Co., Ltd., model number BS-A) was secured with a rubber band, adjusted to 5±0.2 g, and a 20 cm section was cut from the rubber band. 0.8 g of a 5% aqueous solution of sodium lauryl sulfate was applied to the tress, massaged into the hair, rinsed with running water for 1 minute, and air-dried for 24 hours at 20°C and 25% humidity. 2.5 g each of the second agent listed in Table 1 and the first agents listed in Examples 1 to 23 and each Comparative Example was weighed out, mixed in a cup, and applied to the tress using a brush. The mixture was left at 25°C for 20 minutes and then rinsed with running water for 1 minute. The hair was then towel-dried and dried using a hair dryer, and evaluated for "hair moisturization," "hair shine," and "hair firmness and body."

[0052] <Method for evaluating hair moisturization> In the evaluation test relating to "moisturized feeling of hair" shown in this specification, 15 panelists judged whether or not "there is a moisturized feeling of hair" and evaluated according to the following evaluation criteria. <Evaluation criteria for hair moisturization> 5: More than 13 out of 15 people rated their hair as moisturized. 4: Between 10 and 12 out of 15 people evaluated that their hair felt moisturized. 3: Between 7 and 9 out of 15 people evaluated that their hair felt moisturized. 2: Between 4 and 6 out of 15 people evaluated that their hair felt moisturized. 1: Less than 3 out of 15 people rated their hair as moisturized.

[0053] <How to evaluate hair gloss> In the evaluation test relating to "hair gloss" shown in this specification, 15 panelists judged whether or not "hair gloss" was present, and evaluated according to the following evaluation criteria. <Evaluation criteria for hair gloss> 5: More than 13 out of 15 people rated their hair as shiny. 4: Between 10 and 12 out of 15 people rated their hair as shiny. 3: Between 7 and 9 out of 15 people rated their hair as shiny. 2: Between 4 and 6 out of 15 people rated their hair as shiny. 1: Fewer than 3 out of 15 people rated their hair as shiny.

[0054] <How to evaluate hair firmness and strength> In the evaluation test relating to "hair firmness and body" shown in this specification, 15 panelists judged whether or not "hair is firm and body" and evaluated it according to the following evaluation criteria. <Evaluation criteria for hair firmness and strength> 5: More than 13 out of 15 people rated their hair as firm and resilient. 4: Between 10 and 12 out of 15 people rated their hair as firm and resilient. 3: Between 7 and 9 out of 15 people rated their hair as firm and resilient. 2: Between 4 and 6 out of 15 people rated their hair as firm and resilient. 1: Fewer than 3 out of 15 people rated their hair as firm and resilient.

[0055] The evaluation tests of the present invention were carried out using the first agents of Examples 1 to 23 and Comparative Examples 1 to 6 shown in Tables 2 to 4, and the second agents shown in Table 1.

[0056] [Table 1]

[0057] [Table 2]

[0058] [Table 3]

[0059] [Table 4]

[0060] Examples 1 to 23 of the present invention provided good results in terms of moist feeling, hair gloss, and hair firmness and strength.

[0061] Examples 24 to 26 of oxidative hair dyes or bleaches are described below.

[0062] As a first embodiment of the first and second agents of the oxidative hair dye or bleach obtained in Examples 24 to 26, a first inner pouch filled with 56 g of the first agent and a second inner pouch filled with 44 g of the second agent were housed in a single pressure-resistant container, and nitrogen gas was filled as a compressed gas between the inner pouch and the pressure-resistant container as a propellant to an initial internal pressure of 0.7 MPa at 25°C. The container had a double-walled structure, allowing the first and second agents to be simultaneously dispensed at a ratio of 56:44. As a second embodiment of the first and second agents of the oxidative hair dye or bleach obtained in Examples 24 to 26, the first and second agents were each packed in an aluminum tube and mixed at a ratio of 1:1. 5 g of the mixture was used on a tress of black hair treated in the same manner as in Examples 1 to 23 and each comparative example, and favorable results were obtained in each case.
