Description

  The present invention relates to a hair cosmetic composition.

  In the field of hair cosmetics, conventionally, hair modification has been attempted by allowing various components to penetrate into the hair. Among various components for modifying hair, for example, when hair is treated with a hair cosmetic containing a water-soluble compound such as carboxylic acid, saccharide, amino acid, etc., in order to improve the hair treatment efficiency Have made various efforts to promote penetration of water-soluble hair modifying components into hair. For example, Patent Document 1 discloses that by containing a penetration enhancer such as benzyl alcohol in addition to a specific organic acid, highly durable hair deformation is possible without damaging the hair.

  In addition, aromatic sulfonic acids such as naphthalene sulfonic acid and azulene sulfonic acid are known as ingredients that impart hair and strain to hair, and in order to permeate these aromatic sulfonic acids into hair, various penetration enhancements are known. Drugs are being studied. For example, in Patent Document 2, a specific lactam compound has a higher penetration promoting action than benzyl alcohol, which is a generally known penetration enhancer, and is a hair modifying agent such as an aromatic sulfonic acid. -It is disclosed that the penetration of the improver into hair can be further improved.

JP-A-62-298629 JP-A-10-29917

  However, even when these penetration enhancers are used, the expected hair modifying effect is often not obtained sufficiently. In addition, increasing the amount of these penetration enhancers and water-soluble hair modifying components may improve the effect obtained from the water-soluble hair modifying components. In any case, there is an upper limit to the concentration that can be dissolved in water. For this reason, when these are blended at a high concentration, it is common to add an organic solvent such as ethanol in order to obtain a uniform composition. In some cases, the effect was not sufficient.

  Accordingly, the present invention relates to a hair cosmetic composition that is excellent in the permeability of a water-soluble hair modifying component into hair and that provides a high modification effect by the component.

  The present inventor, when trying to dissolve either aromatic sulfonic acid or aromatic alcohol in water, the aromatic sulfonic acid and the aromatic even in the concentration range where it is precipitated without dissolving. It was found that when both of the alcohols were dissolved in water, none of them was precipitated and a uniform aqueous solution was obtained. And if the solution further contains a component (water-soluble hair modifying component) that exerts a hair modifying effect by penetrating into the hair such as carboxylic acid, saccharide, amino acid, etc., these water-soluble hair modifying agents The inventors have found that the component-derived modification effect is excellent, and have completed the invention.

The present invention comprises the following components (A) to (D), the mass ratio (A) / (B) of component (A) to component (B) is from 0.25 to 1, and component (A) and A hair cosmetic composition that may contain the component (E) in such a range that the mass ratio (E) / [(A) + (B)] of the component (E) to the sum of the components (B) is 0.3 or less. It is to provide.

[Examples 1-8, Comparative Examples 1-4]
The hair cosmetics shown in Tables 1 and 2 were prepared and subjected to the following measurements and evaluations.

・ Measurement of particle size The volume average particle size of particles is measured by the “Zetasizer Nano ZS (trade name)”, a particle size distribution analyzer manufactured by Sysmex Corporation based on the principle of the photon correlation method (dynamic light scattering method). used. Measurement conditions were as follows: 2 mL of hair cosmetics described in Examples and Comparative Examples to be measured was collected in a glass cell having an optical path length of 10 mm, placed in a measurement section, and measured at a temperature of 25 ° C.

-Stability The compositions described in Tables 1 and 2 were placed in a transparent container and stored at 25 ° C for one week. After storage, it was visually confirmed whether or not a transparent appearance was maintained.
○: A transparent and uniform state is maintained. ×: Changes in appearance such as precipitation and separation are observed.

[Degree of relaxation]
(Evaluation hair bundle)
Using a Caucasian curly hair with no chemical treatment history, a hair bundle having a length of 30 cm and a weight of 2.0 g when the hair was stretched straight was prepared. After washing this hair bundle with the model shampoo shown below, apply the model rinse shown below, rinse it off, wipe off excess moisture with a towel, and apply the hair dryer to the natural shape of the hair The hair bundle dried for 2 minutes while applying vibration so that the

Wet the hair bundle with tap water at 40 ° C. for 30 seconds, towel dry, apply 0.4 g of the composition described in Tables 1 and 2 and evenly blend on the hair, and then cover the whole hair bundle with a wrap. Sealed and left at room temperature for 15 minutes. After standing, using a dryer (National, EH646) and a brush (manufactured by Beth Kogyo Co., Ltd.), the brush was blown and dried for 2 minutes while repeatedly moving the brush at a speed of 10 cm / second.
Next, an operation in which the vicinity of the root of the hair bundle was sandwiched with a flat iron (GOSSWELL, VOSSGF) at an actually measured temperature of 200 ° C. and slid from the root to the hair tip at a speed of 6 cm / sec was performed three times. The temperature of the iron was measured using a TX10 manufactured by Yokogawa. The hair bundle heated with the flat iron was rinsed with tap water at 40 ° C. for 30 seconds, 1 g of model shampoo was applied, and after lathering for 30 seconds, the model shampoo was rinsed away. Furthermore, 1 g of model rinse was applied, and after 30 seconds of rinsing, the model rinse was rinsed away with tap water at 40 ° C. It was dried for 2 minutes while applying a vibration and applying vibration so that the natural shape of the hair appeared.
The length of the hair bundle (30 cm) when the hair before treatment is straightened and stretched is L, the length of the evaluation hair bundle before treatment after the dryer is L ₀ , and the hair after drying the dryer after treatment The bundle length was defined as L1, and the degree of habit relaxation (%) was determined according to the following formula 1. L ₀ and L ₁ are the lengths measured without hanging the hair bundle from above and pulling it. The results are shown in Tables 1 and 2.
(Formula 1) Degree of relaxation = (L ₁ −L ₀ ) / (L−L ₀ ) × 100
