Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has an excellent volume-up effect and also has a good feel, does not cause bad combing and does not cause flaking (peeling off of the set agent), and has a comb through after drying. Also, the present invention relates to a hair cosmetic such as a hair setting agent, a styling agent, a hair styling agent, and the like, which is capable of combing hair after drying since it hardly causes flaking, thereby making it possible to adjust the volume.

[0002]

2. Description of the Related Art Conventionally, such hair styling materials have been blended with various polymers such as anionic, cationic, nonionic, amphoteric, etc., as central bases, as components for providing a volume increasing effect. Then, it is dissolved in a solvent such as water or a lower alcohol, and a surfactant, an oil or fat, a thickener and the like are appropriately blended and used.

[0003]

However, in these conventional hair styling materials, if a large amount of a setting agent polymer is blended in order to enhance the volume increase effect of the hair, stickiness will be caused in the process of applying to the hair and drying it. This may not be desirable in terms of use, as it may cause combing when using a dryer or the like to make combing worse, or cause stiffness or flaking of the set agent on the dried hair. Was. To solve these problems, various additives such as surfactants, oils and fats, and polyhydric alcohols have been improved. A hair cosmetic having both an effect and an excellent use feeling has not been obtained. Therefore, the object of the present invention is to be able to pass the comb through the dried hair because it has no stickiness or stiffness, has good combability, and hardly causes flaking while having a volume increasing effect. An object of the present invention is to provide a hair cosmetic that can provide a volume-up effect according to personal preference.

[0004]

Means for Solving the Problems The present inventors have conducted intensive studies in order to overcome the problems of the above-mentioned prior art, and as a result, the above-mentioned object was achieved by using a specific acrylic resin and a specific thickening polymer in specific amounts, respectively. When used in combination, it has an excellent volume up effect and also has a good feel, does not cause combing badness and flaking, and hardly causes flaking even after passing through the comb, so after drying The present inventors have found that a hair cosmetic that can be combed into the hair of the present invention and that can be adjusted in volume can be obtained, and the present invention has been completed based on this finding. That is, the present invention provides the following component (A) as an acrylic resin and the following components (B) and (C) as a thickening polymer (A) Acrylic resin alkanolamine 0.0001 to 10% by weight (B) hydroxypropyl cellulose The present invention relates to a hair cosmetic comprising: 0.001 to 20% by weight (C) 0.001 to 10% by weight of an acrylic acid / alkyl methacrylate copolymer.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.
The acrylic resin alkanolamine (A) used in the present invention can be used as a film-forming polymer compound, and the film strength can be adjusted by changing the alkyl group of the ester with an acrylic monomer. The film is transparent, beautiful, and excellent in adhesiveness, and can form a strong film, which is effective for holding a set of hair and imparting a volume increasing effect. However, on the other hand, it is easy to feel sticky and stiff when used alone,
Further, there is a problem that flaking is easily caused after drying. In the present invention, the compounding amount of the component (A) is 0.001 to 10% by weight, preferably 0.01 to 5% by weight, particularly preferably 0.1 to 1% by weight based on the total composition.
% By weight. If it is less than 0.001% by weight, a sufficient film-forming effect cannot be obtained, and if it exceeds 10%, the quality as a hairdressing composition may be impaired.

The hydroxypropylcellulose (B) and the acrylic acid / alkyl methacrylate (C) copolymer can be used as a thickener in hair cosmetics for the purpose of adjusting viscosity. However, when the component (B) and the component (C) are used in combination with the component (A), stickiness and stiffness can be obtained without impairing the excellent set holding power and volume up power that are characteristic of the film formed by the component (A). It was not known at all that it was possible to improve the problems of the coating of the component (A) such as flaking. As a result, it has become possible to provide a hair cosmetic that has a sufficient volume-up effect, has a good feel, and can further improve combing and flaking.

The component (B) used in the present invention, hydroxypropyl cellulose, is hydroxypropyl ether obtained by reacting propylene oxide with cellulose. This material has high thermoreversibility and has a film forming property with a large elongation, but since the film is soft and does not have a sufficient setting effect, it is not blended as a central raw material of the setting agent. It is mainly used for the purpose of adjusting the viscosity of a product, and is used for the purpose of adjusting the viscosity to be easy to use and for maintaining the stability of the product system. However, when the component (B) is used in combination with the component (A), the film formed by the component (A) after drying can give flexibility and a moist feeling, suppress stiffness, improve combability, and improve flaking. The present inventor has found that it has a function to prevent a king.
In the present invention, the compounding amount of the component (B) is 0.001 to 20% by weight, preferably 0.01 to 10% by weight, based on the total composition.
%, Particularly preferably 0.05 to 2% by weight.
If it is less than 0.001% by weight, a sufficient effect of modifying the film formed by the component (A) cannot be obtained, and if it exceeds 20% by weight, the quality as a hairdressing composition may be impaired.

The acrylic acid / methacrylic acid acrylic copolymer, which is the component (C) used in the present invention, also has a thickening effect, and is usually used for the purpose of adjusting the viscosity and maintaining the stability of the product system. . In addition, although this material itself has a weak film-forming property, it cannot be used alone as a setting agent because it cannot set the hair alone to give a sufficient firmness and firmness. However, when the component (C) is used in combination with the component (A), the stickiness at the time of application derived from the component (A) is suppressed, and the hair after drying is not stiff because it has an appropriate moisturizing property. The present inventor has found that a natural feel can be imparted. In the present invention, the compounding amount of the component (C) is 0.001 to 10% by weight, preferably 0.01 to 5% by weight, particularly preferably 0.05 to 1% by weight in the total composition as a resin component. If the amount is less than 0.001% by weight, a sufficient effect of modifying the film formed by the component (A) cannot be obtained. If the amount exceeds 10% by weight, the quality as a hairdressing composition may be impaired.

The hair cosmetic of the present invention may contain, in addition to the above essential components, other optional components as long as the effects of the present invention are not impaired. For example, other nonionic, anionic, cationic, amphoteric polymers and silicone oils such as polyvinyl alcohol, silicones such as highly polymerized silicone, cyclic silicone, polyether-modified silicone, amino-modified silicone, and cationic silicone;
Citric acid for adjusting pH and viscosity; acids such as lactic acid; glycerides such as jojoba oil and olive oil; waxes such as lanolin; hydrocarbons such as liquid paraffin and squalane; linear and branched higher alcohols, glycerin; 3
-Polyhydric alcohols such as butylene glycol; esters such as isopropyl myristate and 2-ethylhexanoic acid diglyceride; anionic, cationic, nonionic or amphoteric surfactants; protein derivatives such as collagen and keratin hydrolysates And amino acids; plant extracts;
Other components commonly used in hair cosmetics, such as ultraviolet absorbers, fragrances, bactericides, vitamins, preservatives, antioxidants, chelating agents, and pigments.
