Abstract

By using (A) chitosans and (B) polyurethane resin in combination, they are damaged and weakened by chemical treatments such as coloring and perms, give firmness and firmness to thin and soft hair, and follow the fingers. It is possible to provide a hair cosmetic composition that can be finished supple and supple, can prevent stickiness and wrinkle, and can provide a good hair feel.

Description

  The present invention relates to a hair cosmetic, and more particularly, to a hair cosmetic that gives firmness and firmness to damaged thin soft hair, suppresses stickiness and stiffness, and finishes smoothly and smoothly according to the finger.

  Usually, hair is damaged by daily hair care and hair makeup behavior. It is known that in daily shampooing behavior, the sebum and hair constituent proteins of the hair are eluted by the surfactant as the main component, and the cuticle is peeled off by repeated daily blows. Yes. In addition, the frequency of cold perms, hair coloring, hair bleaching, etc. has increased due to the increased awareness of fashion, and chemical treatment with chemicals has promoted elution and structural changes of hair constituent proteins, which has spurred damage.

  In addition, hair that has been born with a narrow diameter or that has become thinner and softer with age has the inherent problem that it is difficult to style due to the lack of elasticity, volume, and damage as described above. In other words, the styling property is further deteriorated, and the touch surface such as a squeaky feeling or a crisp feeling tends to be remarkably deteriorated.

  For such problems, hair cosmetics containing a film-forming resin such as polyacrylic acid or polyvinyl polymer have been proposed for the purpose of giving firmness and firmness to thin hair and facilitating styling. However, although these hair cosmetics give a firmness and firmness, the feeling of stickiness and squeakiness is expressed and the touch is lowered, and the film formed on the hair is also easily broken down by physical force and moisture, There was a problem that the firmness and firmness decreased with time.

  Therefore, conventionally, there has been a strong demand for imparting a firmness, firmness, and volume to the hair without impairing the natural touch of the hair. Against this background, several methods have been proposed. For example, methods for penetrating and supplementing hair with components similar to hair such as collagen derivatives and keratin derivatives have been proposed (Patent Document 1: Japanese Patent Laid-Open No. 60-243010, Patent Document 2: Japanese Patent Laid-Open No. 2-53712). Issue gazette). In addition, a method of coating the hair surface with a natural polymer compound has also been proposed (Patent Document 3: Japanese Patent Laid-Open No. 59-65008, Patent Document 4: Japanese Patent Laid-Open No. 62-36308, Patent Document 5: Special). JP-A-62-29404, Patent Document 6: JP-A-62-221615, Patent Document 7: JP-A-1-0099911, Patent Document 8: JP-A-4-308525, Patent Document 9: 1-249711 gazette).

  However, with these methods, there are cases where improvement in the touch surface is observed, but it is easy to style by giving firmness and volume to the thin and soft hair weakened by the damage, and the deterioration of the touch due to the damage. It was not really satisfactory with respect to the effect of improvement. That is, a hair cosmetic composition that imparts a firmness and firmness that is sufficiently satisfied with styling properties to hair damaged by thin, soft hair quality, suppresses stickiness and stiffness, and has an effect of improving the feel of damaged hair. It was desired.

Evaluation method After hair treatment and coloring treatment, 10 g (30 cm) of fine hair (average hair diameter 65 ± 10 μm) with a reduced touch feeling, shampoo, rinse, hair after applying 0.8 g of sample and drying Based on the following scores, the 10 panelists evaluated the “feeling of firmness”, “goodness of fingers”, “smoothness”, “noness of stickiness”, “no stickiness”, and “noness of wrinkles” did. The results were shown based on the following evaluation criteria from the total score obtained.
Score
<Harness and firmness of hair>
Compared with untreated hair (shampooed and rinsed with the above evaluation method, sample uncoated hair)
+2 points: I felt a firmness and firmness.
+1 point: I felt a little bit of elasticity.
0 points: Neither.
-1 point: I do not feel much elasticity or stiffness.
-2 points: I do not feel a firmness or stiffness.
<Good fingering, suppleness, no creaking, no stickiness, no stickiness>
+2 points: Very good, +1 point: Slightly good, 0 point: Neither, -1 point: Slightly bad, -2 point: Very bad
The total score of 10 evaluation criteria is ◎: 15 points or more ○: 14-6 points Δ: 5-0 points ×: -1 points or less

  Examples of hair cosmetics are shown below, all of which are `` harsh and firm '', `` good for the fingers '', `` flexible '', `` no creaking '', `` no stickiness '', `` no stickiness '' "Was good.

  In addition, about a main raw material used for the said Example, a brand name and a maker are shown in the following list.

4-glyceryl gallic acid synthesis method * 1
To a mixed solution of 36.8 g of methyl gallate, 300 mL of acetone, and 60 mL of DMF (dimethylformamide), 33.2 g of potassium carbonate was added, stirred, heated, refluxed for 20 minutes, and then 24.2 g of allyl bromide was added dropwise. Refluxed for another 5 hours. After distilling off the solvent under reduced pressure, 200 mL of ethyl acetate and 200 mL of water were added for liquid separation, and the resulting organic layer was washed with 100 mL of saturated brine and concentrated. To the obtained residue, 300 mL of hexane was added and stirred to obtain crude crystals as a precipitate. After the hexane solution was decanted, the crude crystals were crystallized using ethyl acetate and hexane, which was collected by filtration and dried to obtain 9.4 g of methyl 4-O-allyl gallate.
In a mixed solution of 6 mL of formic acid and 6 mL of 30% hydrogen peroxide solution, 2 g of methyl 4-O-allyl gallate obtained by the above method was adjusted while adjusting the temperature so that the internal temperature was 30 to 35 ° C. The reaction was divided into several times and added over 1 hour, and the reaction was continued for 2 hours while adjusting the temperature so that the internal temperature was 35 to 40 ° C. 20 mL of water and 30 mL of toluene were added to the reaction system for liquid separation, and after removing the toluene layer, 30 mL of ethyl acetate was added to the aqueous layer for liquid separation extraction. Further, 30 mL of ethyl acetate was added to the aqueous layer to perform re-extraction, and combined with the previous ethyl acetate layer. The organic layer was washed successively with 20 mL of water, 20 mL of aqueous sodium bicarbonate, and 20 mL of aqueous sodium bisulfite solution, and then washed with aqueous sodium hydroxide solution until the aqueous layer became neutral. After confirming that no peroxide remained on potassium iodide starch paper, the mixture was concentrated and the resulting residue was purified by silica gel column chromatography (silica gel 60 g, developing solvent: hexane / ethyl acetate = 1). / 4 (volume ratio)). The obtained 4-glyceryl gallic acid methyl ester and its formate were combined to obtain 0.35 g. This was added to an aqueous solution of 1 mL of water and 0.2 g of sodium hydroxide, and reacted at room temperature for 3 hours. 14 mol / L hydrochloric acid was added to adjust the reaction solution to pH 1. The precipitated crystals were collected by filtration, then shaken with 2 mL of water and dried to obtain 0.20 g of 4-glyceryl gallic acid powder.
