Description

  The present invention relates to a hair cosmetic that is excellent in hair styling power, re-hair styling power, and moisturizing power, and is not stiff.

  In recent years, gel-like or wax-like hair cosmetics for the purpose of styling have been frequently used. In general, these hair cosmetics contain a film-forming agent such as a water-soluble polymer in order to obtain sufficient hair-styling retention power. However, the hair-styling retention power decreases due to moisture absorption over time or the film-forming agent. Problems such as flaking due to solidification of powder and difficulty in re-styling hair have been pointed out.

  In order to solve these problems, for example, in Patent Document 1, in a gel hair dressing containing an alkali thickener and an alkali agent, a nonionic resin comprising 0.5 to 7.5% by weight of a vinylpyrrolidone copolymer is used. The polymer is mixed with 20 to 40% by weight of ethanol and polyhydric alcohol, and the weight ratio of ethanol to polyhydric alcohol is set to 1: 1.5 to 1: 4. It is described that the coating property, the moisturizing power, and the hair styling power are improved.

  Patent Document 2 contains a water-soluble polymer, at least one selected from glycerin, saccharides, polyalkylene glycol and / or derivatives thereof, and 1,2-alkanediol having 5 to 10 carbon atoms. A hair cosmetic composition is disclosed, which suppresses stickiness and film feeling and is superior in texture.

  Patent Document 3 describes a waxy hair styling agent containing a vinyl pyrrolidone film forming agent, a cationic surfactant, a higher alcohol and glycerin and / or polyglycerin, and imparts the original hair styling power of the film forming agent. It is said that it suppresses a reduction in hair holding ability and is excellent in moisture resistance.

  However, hair styling agents such as those described in Patent Documents 1 to 3 are not sufficient in hair styling power and style holding power even if the moisture retention is improved by blending glycerin, propylene glycol or the like.

Therefore, the subject in this invention is providing the hair cosmetics which have the hair styling power and re-hair styling power which were superior to the conventional hair styling agent, and the set holding | maintenance power, and there was no wrinkle and also improved the moisture retention power.
As a result of intensive studies to solve the above-mentioned problems, the present inventors combined diglycerin and sugar alcohol with a resin, and adjusted their blending amounts within a specific range to achieve the desired characteristics. The present inventors have found that a hair cosmetic composition having a hair color can be obtained, and have completed the present invention.

That is, the present invention
(A) 5-30% by mass of diglycerin,
(B) 5-25% by weight sugar alcohol,
(C) 1-10 mass% resin and (D) water-soluble thickener are contained, and the sum total of the compounding quantity of said (A) diglycerin, (B) sugar alcohol, and (C) resin is 15-40. Provided is a hair cosmetic characterized in that the content is% by mass.

  The composition which concerns on this invention mix | blended resin, diglycerin, and sugar alcohol in combination with a predetermined | prescribed compounding quantity, and also improved the hair-styling power by mix | blending a water-soluble thickener. In particular, by blending diglycerin and sugar alcohol at the same time, the moisturizing effect over time is improved compared to cosmetics blended with glycerin and propylene glycol used in the prior art, and the resin does not solidify completely. Re-hairdressing became possible.

  Diglycerin (component A) blended in the hair cosmetic composition of the present invention accounts for 5 to 30% by mass, preferably 5 to 25% by mass, more preferably 5 to 20% by mass of the entire composition. If the blending amount is less than 5% by mass, sufficient moisturizing power cannot be obtained, the hair becomes stiff and re-styling may become difficult. When it mixes exceeding 30 mass%, stickiness will be produced and it will become a heavy touch, a style holding power may fall and it may become difficult to re-hair.

The sugar alcohol (component B) blended in the hair cosmetic composition of the present invention has an action of improving the moisturizing power in cooperation with the diglycerin. Conventionally, hair cosmetics containing both diglycerin and sugar alcohol at the same time have not been known.
The sugar alcohol used in the present invention is not particularly limited, but for example, one or more selected from sorbitol, maltitol, and mannitol are preferably used. These can also use a commercial item, for example, Sorbit 70S (brand name), Mabit (brand name), D-mannit (brand name) etc. can be mentioned.

  The compounding quantity of the sugar alcohol in the hair cosmetics of this invention is 5-25 mass%, Preferably it is 5-20 mass%. When the blending amount is less than 5% by mass, the hair styling power and the style holding power are lowered, and sufficient hair retention power is not exhibited, so that re-hair styling may be difficult. If the blending amount exceeds 25% by mass, the hair styling power and the style holding power are also lowered, which may cause wrinkles.

  The resin (component C) blended in the hair cosmetic composition of the present invention is a polymer resin corresponding to a water-soluble polymer or film forming agent blended in a conventional hair cosmetic composition (hairdressing agent). Specifically, nonionic (vinyl pyrrolidone / vinyl alcohol) copolymer, polyacrylate cross polymer 3, polyurethane-24, polyurethane-10 glucan, anionic carrageenan, amphoteric alkyl methacrylate copolymer, and the like. It is particularly preferable to use one or more selected. Commercially available products can be used as they are, for example, PVP / VA-ETW, plus size L-64S, Aqualinker SU-100, Aquagel I-2, curdlan, Yucaformer 301, Yodosol PUD ( Any of them may be trade names).

It is preferable that the compounding quantity of the resin in the hair cosmetics of this invention shall be 1-10 mass%. When blending two or more resins, it is preferable to blend so that the total blending amount of the resin is 1% by mass or more.
In the hair cosmetic composition of the present invention, the total amount of diglycerin (component A), sugar alcohol (component B), and resin (component C) is 10% by mass or more in order to have sufficient hair styling power and style retention power. Preferably there is. When it exceeds 40 mass%, it is not preferable at the point of use feeling. The mixing ratio of each component A to C can be appropriately adjusted according to the intended hair cosmetic.

  The hair cosmetic composition of the present invention contains a water-soluble thickener (component D) in addition to the components A to C. The water-soluble thickener used in the present invention may be one conventionally used in the cosmetics field, and is not particularly limited. For example, carboxyvinyl polymer (carbomer; sinterene (trade name), etc.), (acrylic acid) / An alkyl acrylate (C10-30)) copolymer, xanthan gum, anionic such as sodium polyacrylate, cationic such as polyacrylate-1, hydroxyethylcellulose, methylcellulose, hydroxypropylmethylcellulose, (behenic acid / eicodioic acid) glyceryl Nonionic thickeners such as are preferably used.

The compounding quantity of the water-soluble thickener in the hair cosmetic of this invention is 0.05-5 mass%, Preferably it is 0.1-2 mass%.
Although not limited, as a combination of the resin and the thickener blended in the hair cosmetic composition of the present invention, when the thickener is anionic, the resin is preferably anionic and nonionic. When the thickener is cationic, the resin is preferably cationic, nonionic and amphoteric. This is because in the case of a thickener using an electrostatic thickening mechanism, the charge of the thickener may be canceled by the opposite charge of the resin, and thickening may not be possible.

  Moreover, it is preferable that the hair cosmetic composition of the present invention does not contain 1% by mass or more of a solid oil component having a melting point of 25 to 100 ° C. When such a solid oil is blended in an amount of 1% by mass or more, a heavy feel or stickiness may occur on the hair that has been trimmed by the resulting hair cosmetic.

In addition to the components A to D described above, the hair cosmetic of the present invention may be blended with other components conventionally used in hair styling and the like as long as the effects of the present invention are not impaired.
For example, by further blending an activator having a phytosterol skeleton and a triazine ultraviolet absorber, damage to the hair due to ultraviolet rays can be further reduced.

Hereinafter, the present invention will be described in more detail with specific examples, but the present invention is not limited to the following examples. Moreover, the compounding quantity in a following example etc. shows the mass% unless there is particular notice.
