Description

  The present invention relates to a hair treatment agent that reduces the change over time of the coloring component contained in the composition and is excellent in storage stability, in particular, a permanent wave and a first agent for straightening hair.

  Hair treatment agents are often colored for various reasons. For example, the coloring component is used for the purpose of reflecting the image of the product or distinguishing it from other items. In particular, permanent wave agents and hair straighteners are used to prevent misuse when the dosage forms of the first and second agents are similar, or to avoid the confusion of types such as hardware and software in the series. Is also an important factor.

  However, in hair treatment agents that contain a large amount of alkaline agents and reducing agents, such as permanent wave agents and hair straighteners, the stability of the coloring component is extremely poor. This is a completed task. For example, relatively stable pigments such as yellow No. 203, orange No. 205, green No. 201, gardenia blue pigment, etc. have been found and have been used for a long time.

  In Patent Document 1, the first agent for permanent wave filled in a 1 mm-thick vinyl chloride container is identified using three kinds of these relatively stable specific pigments. However, a plastic film thin container that is not as light-shielding as a 1 mm thick PVC container, such as a milky white pouch made of polyethylene with a thickness of about 0.2 mm that is frequently used for refilling applicators and pump containers. I was waiting for the best solution because I couldn't escape the fading caused by ultraviolet rays.

  In addition, due to environmental problems, PVC containers that may generate dioxins during incineration and the reduction of waste volume are being screamed in recent years, and replacement with thin bags such as the above-mentioned pouches is progressing. It has become a serious problem for the industry.

  JP 2002-179537 A   JP-A-11-302139   JP 2005-281191 A   Japanese Patent Laid-Open No. 2002-53436   JP 2003-146844 A

  In view of the above-mentioned problems of the prior art, the present invention reduces the discoloration of the coloring component contained in the composition, and has excellent storage stability, particularly a permanent wave and a first agent for straightening hair. It is to provide.

A hair treatment agent comprising the following components (A), (B) and (C) is provided.
(A) Coloring component, 0.00001% by weight or more and less than 0.1% by weight.
(B) Lanolin, 0.1 wt% to 10 wt%.
(C) 1 type (s) or 2 or more types chosen from glycyrrhizic acid and its salt, or a glycyrrhetic acid derivative, 0.001 weight%-1 weight%.

  Further, the component (A) is preferably one or more selected from direct dyes and plant-based natural coloring components, and the component (C) is preferably dipotassium glycyrrhizinate.

  The hair treatment agent of the present invention was a hair treatment agent that reduced the change over time of the coloring component contained in the composition and was excellent in storage stability.

  The coloring component which is the component (A) of the present invention includes natural coloring components extracted from plants, in addition to direct dyes such as acidic dyes, neutral dyes and basic dyes.

  As acid dyes, red No. 102, No. 106, No. 201, No. 227, No. 401, Yellow No. 4, No. 202, No. 203, No. 403, No. 406, No. 407, Blue Legal dyes such as No. 1, No. 2, No. 205, Green No. 3, No. 201, No. 401, Purple No. 401, Black No. 401 and Orange No. 205 are listed.

  Neutral dyes include HC Red3, Yellow2, Yellow4, Orange1 and Blue2, and other disperse dyes such as Disperse Black9 and Violet1, and 2-Amino-6-Chloro-4-Nitrophenol (trade name). And nitro dyes such as HUCOL 2A6).

As basic dyes, Basic Red76 (trade name: ARIANOL MADDER RED (H)), Yellow57 (same: STRAW YELLOW (H)), Brown17 (same: SIENNA BROWN (H)), Brown16 (same: MAHOGANY) (H)), Blue99 (same: STEEL BLUE (H)), Blue3, and Violet10 (legal dye: red No. 213).

  However, when blended with permanent wave or curly hair straightener, it is desirable to blend the above acidic dye and red No. 213 (basic dye) since the current method cannot use anything other than legal pigments.

  As the plant-based natural coloring component in the present invention, those extracted from any plant can be used. However, when used in permanent waves and hair straighteners, the current methods that can be used are turmeric (yellow), β-carotene (yellow), guaiazulene (blue), gardenia (yellow, blue), cochineal (red), shikonin (Purple), chlorophyll (green), safflower (red, yellow), etc., but some of these have other effects besides coloring, so they can be used according to the purpose. It is more preferable because it can be expected to have an anti-inflammatory effect on the skin.

  Patent Document 2 proposes a hair treatment agent for hair dyeing permanent wave or hair straightening containing 0.1% to 10% by weight of these coloring components, but the hair treatment agent in the present invention is dyed. Since the hair is not intended, the blending amount may be 0.00001 wt% or more and less than 0.1 wt%, preferably 0.0005 wt% to 0.05 wt%. If it is less than 0.00001% by weight, a coloring effect cannot be obtained, and if it is more than 0.1% by weight, hair is dyed, which is not preferable.

  Examples of natural coloring components other than plant-based natural coloring components include mineral-based coloring components such as red iron oxide (Bengara), yellow iron oxide, Gunjo (ultraviolet), and conger (bituminous). However, when blended with a permanent wave or a hair straightener, the reducing agent and metal ions react with each other, which is not preferable. Examples of animal-based coloring components include pigments such as squid, krill, and grosphyrin, which are not preferred because they are not well supplied and the image is not good.

  Lanolin, which is the component (B) of the present invention, is known as an oil having a water-holding property as described in Patent Document 3, and is also used in various cosmetics and hair treatment agents (Patent Document 4 and Patent Document). 5). However, in the present invention, in addition to the known properties of lanolin, the inventors have found an effect that contributes to the stabilization of the coloring component.

  Examples of commercially available lanolin include super lanolin (manufactured by Croda Japan), lanolin (manufactured by Ina Trading Co., Ltd.), and YOFCO lanolin (manufactured by Nippon Seika Co., Ltd.). In the case of blending, since the original purpose is served, the blending amount is 0.1 to 10% by weight, preferably 0.5 to 5% by weight in the hair treatment agent. If it is less than 0.1% by weight, the anti-fading effect cannot be obtained, and if it exceeds 10% by weight, the hair treatment agent becomes too oily, which is not preferable.

  Examples of the glycyrrhizic acid and its salt, or glycyrrhetinic acid derivative, which are the component (C) of the present invention, include dipotassium glycyrrhizinate (dipotassium glycyrrhizinate), stearyl glycyrrhetinate and disodium succinylglycyrrhetinate (disodium carbenoxolone). It is done.

  These glycyrrhizic acids and salts thereof or glycyrrhetinic acid derivatives have been conventionally incorporated into hair treatment agents in anticipation of anti-inflammatory effects. However, like the component (B), the present invention has newly found the anti-fading effect of the coloring component. As commercially available products, Maruzen Pharmaceutical Co., Ltd. glycyrrhizin (registered trademark, indicated by (R) below) K2 (dipotassium glycyrrhizinate), Sea Au Gretinol (R) (stearyl glycyrrhetinate) and 3-succinyloxy produced by the company Examples include glycyrrhetinic acid disodium (succinylglycyrrhetinic acid disodium salt) and the like.

  As a compounding quantity, 0.001 weight%-1 weight% are preferable, and 0.005 weight%-0.1 weight are more preferable. If the amount is less than 0.001% by weight, the effect cannot be obtained, and if the amount exceeds 1% by weight, the effect does not change so much, which is uneconomical. Among these components (C), dipotassium glycyrrhizinate is particularly preferable because it is water-soluble and easy to handle.

  The hair treatment agent in the present invention contains a reducing agent for deformation or softening of the hair. For example, in addition to the first agent for permanent wave or hair straightener, it is used in the form of pre-treatment agent, intermediate treatment agent, post-treatment agent, curling agent, shampoo, hair rinse, hair conditioner, hair conditioner, etc. It is done.

  Examples of the reducing agent include thioglycolic acid or ammonium thioglycolate and salts thereof such as thioglycolic acid monoethanolamine, cysteine or cysteine hydrochloride, and derivatives thereof such as acetylcysteine, cysteamine or hydrochloride thereof, thiolactic acid or In addition to the salts and thiol compounds such as thioglycerin, sulfites and hydrogen sulfites are exemplified, and the blending amount is usually about 1 to 15% by weight. However, in the case of the permanent wave or the first agent for straightening hair, be aware that there are legal restrictions on the components and the amount that can be used.

  Moreover, in order to make it alkaline (pH = 7 to 13), the hair treatment agent in the present invention appropriately contains an alkali agent and / or a pH buffer as necessary. These components may be known components that are usually used, for example, amines such as ammonia water and monoethanolamine, alkali agents such as hydroxides, carbonates, bicarbonates, and citric acids of alkali metals and amines. PH buffering agents, such as a salt, hydrogen citrate, phosphate, and hydrogen phosphate, are mentioned, These 1 type (s) or 2 or more types are normally used in combination.

  Furthermore, the hair treatment agent according to the present invention can be blended with any component used in ordinary hair treatment agents as long as the intended effect is not impaired. For example, a solvent, a humectant, an antiseptic, a flavoring agent, an anti-inflammatory agent, an antistatic agent, an ultraviolet ray preventing agent and the like can be mentioned.

  EXAMPLES Next, although an Example is given and this invention is demonstrated in detail, this invention is not limited to these. The blending amount is% by weight.
