Description

hair cosmetics

The present invention relates to a hair cosmetic.

Hair can be damaged by living environment (ultraviolet rays or heat generated by sunlight), daily hair care behaviors (friction caused by shampooing or brushing), and chemical treatments (coloring, perming, etc.). If damaged hair rubs against each other, greater friction will be generated on the surface, causing tangles. "Hair tangles" become the cause of all stress in hair care practices. "Tangled hair" may be felt due to poor combability when foaming shampoo and other hair cleansers, and poor combability when rinsing hair after shampooing. As a method to untangle hair after shampooing, when using hair cosmetics such as conditioner or conditioner, apply the hair cosmetics to the hair and unclog the tangled areas with your fingers. Penetrates, spreading the lubricating ingredients over the hair surface and untangling the hair. In the previous technology, for the purpose of improving the combability or combability of hair, cationic surfactants, higher alcohols, polysiloxanes, etc. were blended into hair cosmetics such as hair conditioners and hair conditioners. .

Patent Document 1 discloses a hair cosmetic that uses polyetheramine-modified polysiloxane and a cationic surfactant to suppress the dry feeling of hair in the water flow and improve softness or smoothness during rinsing. This can prevent damage caused by tangled hair during rinsing. In Patent Document 2, it is disclosed that amine-modified polysiloxane, amino-polyether-modified polysiloxane, dimethyl polysiloxane, and specific kinematic viscosity range are used in a specific kinematic viscosity range. Hair cosmetics composed of alkyl cations and specific higher alcohols can improve the moisture retention of hair, improve combability during use, give a soft and moist feeling, and prevent dryness and dryness in low humidity. Gives a moist feel. Prior technical literature patent documents

[Hair cosmetics] The hair cosmetic of the present invention is characterized by containing or blending the following components (A), (B), and (C). (A) Amino polyether-modified polysiloxane containing a polyoxyalkylene structure that satisfies the following formula (I) 0.01≦Si/AO≦1.6 (I) [In formula (I), Si represents the mole number of silicon atoms in component (A), and AO represents the average mole number of oxyalkylene groups added in component (A)] (B) Amino polyether-modified polysiloxane containing a polyoxyalkylene structure that satisfies the following formula (II) 1.6＜Si/AO≦3.0 (II) [In formula (II), Si represents the mole number of silicon atoms in component (B), and AO represents the average mole number of oxyalkylene groups added in component (B)] (C) Cationic surfactant The hair cosmetic of the present invention contains or blends the above-mentioned ingredients (A), (B), and (C), and when applied to cleansed hair, it can remove the residue after shampooing without performing operations such as manual dredging. It can remove tangled hair and give it a moisturizing feel after drying. Furthermore, "containing ingredients (A), (B), and (C)" also means "comprising ingredients (A), (B), and (C)."

Although any of the hair cosmetics described in Patent Documents 1 and 2 improve the smoothness and combability of the hair during use, they cannot spontaneously untangle the hair caused by shampooing without manual dredging and other operations. The tangle. The present invention relates to a hair cosmetic that, when applied to cleansed hair, can untangle the hair after shampooing without manual unclogging and other operations, and can provide a moisturizing touch to the dried hair.

The present inventors discovered that a hair cosmetic containing or blending two types of amino polyether-modified polysiloxane containing a polyoxyalkylene structure and a cationic surfactant that satisfies specified necessary conditions can solve the problem. the above issues. The hair cosmetic according to the present invention, when applied to cleansed hair, can untangle the hair after shampooing without performing operations such as hand unclogging, and can provide a moisturizing feel to the dried hair.

The reason why the effect of the present invention is exerted by having the hair cosmetic of the present invention have the above-mentioned constitution is not certain, but it is speculated as follows. In order to achieve a state in which the tangles of hair existing after shampooing can be spontaneously undone, it is considered important to reduce the friction force acting on the hairs. Polysiloxane is generally blended as an active ingredient in hair cosmetics, but the inventors found that in order to reduce the friction between hairs, it is effective to use a water-soluble polyoxyalkylene structure with a high ratio. The amino polyether modified polysiloxane is component (A). Furthermore, they found that by using component (A) in combination with component (B), a water-insoluble amino polyether-modified polysiloxane having a low polyoxyalkylene structure content ratio, hair after drying can be given a moisturizing effect. The moisturizing feel can more effectively untangle the hair caused by shampooing. The cationic surfactant as component (C) has the effect of dispersing the water-insoluble component (B) in the hair cosmetic. In addition, anionic surfactants are blended in order to express cleansing properties in hair cleansers such as shampoos. However, by making the hair cosmetic of the present invention contain component (C), it can be applied to cleansed hair. Gives good hair care effect.

[Example]

Hereinafter, the present invention will be described through examples, but the present invention is not limited to the scope of the examples. Furthermore, in this example, various measurements and evaluations were performed by the following methods.

(Measurement of Si/AO in component (A) and component (B)) Weigh 10 mg of component (A) and component (B) (amino polyether modified polysiloxane 1 to 3) used in each example. Take it from a No. 3 screw-top bottle and dry it overnight in a nitrogen atmosphere. To the obtained dried product, 1 ml of deuterated chloroform (manufactured by Wako Pure Chemical Industries, Ltd.: chloroform-d, 99.8%) was added and dissolved, and then ¹ H-NMR (manufactured by BRUKER JAPAN Co., Ltd., JH074504 AV400) was performed. From the integral value of the dimethylsilyl group (6H: -0.3~0.3 ppm) bonded to silicon and the integral value of the oxyethylene (EO) chain (4H: 3.3-3.9 ppm), the following formula is used to calculate Si/ AO unit ratio. [Formula 1]

(Combing load measurement) Using Japanese straight hair, make a hair bundle for evaluation with a mass of 20 g, a length of 30 cm, and a width of 5.5 cm (the hair bundles are damaged by bleaching with bleach as described below). Use the following ordinary shampoo to clean the hair bundles, comb them through with your hands when rinsing to untangle them, and fully moisten them in warm water at 35 to 40°C. Apply ordinary shampoo to the hair bundles again, clamp the ends and roots of the hair in the palms of your hands, rub them together in a circular motion, and lather the hair in a circular motion. The hair bundles were rinsed with warm water for 30 seconds without unclogging them by hand at all. After wringing out the water with hands, they were immersed in 1 L of each example of hair cosmetic placed in a 1 L beaker. Shake the hair bundle about 5 times in a beaker and take it out. When the water content of the hair bundle reaches 20 g, measure the load applied to the hair bundle when it is initially combed according to the following method. The above-mentioned hair bundles were set on a combing force measuring device ("KOT-0303" manufactured by Utsunomiya Seiki Co., Ltd.), and a comb (rib comb) was arranged in 5 rows with an interval of 5 mm on a surface of 2.5 cm in width and 9.0 cm in length. Two needles (with a diameter of 1 mm and a length of 2 cm) are set up to clamp the uppermost part of the hair bundle, and the load (gf) applied when the comb is unclogged to the end of the hair is measured. The load is measured every 1.5 mm of a hair bundle with a length of 30 cm, and the maximum value of a total of 200 measured values is used as the combing load. Furthermore, when purified water is used instead of hair cosmetics, the combing load is 2055 gf, which is the upper limit of measurement. If the combing load is less than 2055 gf, it will have the effect of untangled hair after shampooing, and the smaller the combing load value means the higher the effect.

[Bleaching treatment method] Mix 7 mL of Kao Foam Hair Bleach L (1 liquid) and 14 mL of Kao Foam Hair Dye (2 liquids), apply it to a hair bundle with a mass of 20 g, let it sit for 20 minutes, and then rinse with warm water at 35 to 40°C. Rinse thoroughly. This operation was repeated twice to prepare hair bundles for evaluation.

(Tactile evaluation of dry hair) After fully moistening the hair bundles for evaluation prepared in the combing load evaluation with warm water at 35 to 40°C, clean them with the above-mentioned ordinary shampoo. After wringing out the water, immerse it in 1 L of the hair cosmetic prepared in each example for 1 minute. After taking it out, rinse it with warm water at 35 to 40°C for 30 seconds, wipe off the water with a towel, and dry it with a hair dryer. The tactile evaluation of completely dry hair bundles was carried out by 5 sensory examiners. The evaluation was made on a five-level basis, with "moisturizing" being set to 5, "not moisturizing" being set to 1, and Comparative Example 1 being set to a base score of 4.0. The average scores (rounded to the second decimal place) evaluated by the five sensory examiners are shown in Table 1. If the average score of 5 sensory examiners is 3.5 or above, it can be judged that the dried hair has a moisturizing feel. (Evaluation Basis) 5 moisturizing 4 Slightly moisturizing 3 It’s hard to say which side it is 2 Hardly moisturizing 1 Not moisturizing

Examples 1 to 4, Comparative Examples 1 to 2 (Preparation and Evaluation of Hair Cosmetics) According to the ingredients shown in Table 1, the hair cosmetics (hair conditioners) of each example were prepared according to the following method, and evaluated. Put ingredient (A) and 500 g of purified water into a 1 L beaker and stir. After adding lactic acid dropwise to the obtained liquid, component (C) was added, the beaker was immersed in a water bath, and the temperature was raised to 75°C. Then, after adding the premixed higher alcohol and dipropylene glycol, the mixture was stirred at 75° C. for 10 minutes, taken out from the water bath, and started to cool. Add component (B) and the remaining purified water, and cool to below 40°C while stirring to obtain 1 L of liquid hair cosmetic. Using this hair cosmetic, evaluation was carried out by the above method. The results are shown in Table 1. In addition, the compounding quantity described in Table 1 is the active ingredient quantity (mass %) of each component.
