Description

[Technical field]

[0001] The present invention relates to a hair treatment agent or a fiber treatment agent for head accessories such as wigs and extensions, and more particularly to a wash-off type hair cosmetic product such as a hair rinse, hair conditioner, hair treatment, or hair pack that is used after shampooing. [Background technology]

[0002] Rinse-off hair cosmetics such as hair rinses and hair conditioners used after shampooing contain cationic surfactants and higher alcohols as main ingredients, and are intended to improve the surface condition of hair by imparting smoothness and a moist feeling to hair. For example, Patent Documents 1 to 3 disclose hair cosmetics that contain cationic surfactants, higher alcohols, silicones, etc. and impart a pleasant feel to hair.

[0003] Patent Document 1 discloses a hair cosmetic composition that combines a specific hydroxyamine, a quaternary ammonium salt, a higher alcohol, an amino group-containing silicone derivative selected from several options, and a methylpolysiloxane, which gives hair a soft and moist finish without stickiness, and provides excellent finger-combability and softness when rinsing.

[0004] Patent Document 2 discloses a hair conditioning composition that combines two types of silicones that do not contain an amino group with a silicone that contains an amino group, and mixes the combined silicones with a gel matrix that contains a quaternary ammonium salt type cationic surfactant and a high-melting point aliphatic compound, and that provides improved conditioning effects such as a smooth feel and reduced friction.

[0005] Patent Document 3 discloses a hair cosmetic composition which contains a quaternary ammonium salt type cationic surfactant, a higher alcohol, a phosphate group-containing silicone compound, and an amino-modified silicone compound, and which has good emulsion stability, is excellent in maintaining the smooth feeling and manageability of hair, and is less sticky.

EXAMPLES

[0161] [Examples 1 to 19 and Comparative Examples 1 to 8] The hair conditioners shown in Tables 5 and 6 were prepared by the following manufacturing method, and the appearance was observed or the viscosity was measured, and the durability of the conditioning effect (combing force) on wet hair after the first wash and after the third wash was evaluated according to the following methods and criteria. The contents shown in the tables are the active amounts.

[0162] (Manufacturing method) Hair conditioners were prepared according to the following procedure using the components in the amounts shown in Tables 5 and 6. To obtain a total volume of 500 mL of hair conditioner, each component was mixed in an amount 5 times (mL) the amount shown in the table. In a 500 mL beaker containing water, cetrimonium chloride (component (B)) or steartrimonium chloride (component (B')) and lactic acid (40% of the total amount) were added and heated and stirred at 56 ° C. Next, a cationic surfactant (component (A) or (A')), a higher alcohol (component (C)), and benzyl alcohol were mixed in advance, and the oily phase obtained by dissolving at 76 ° C. was added and stirred at 56 ° C. for 10 minutes. After stirring for 10 minutes, heating was stopped and air cooling was started. After air cooling, silicones (components (D) and (E)) as shown in each table, as well as malic acid and the remaining lactic acid were added, and the mixture was cooled with stirring until the liquid temperature reached 40 ° C. or less, to obtain 500 mL of hair conditioner.

[0163] (Appearance evaluation) The hair conditioners shown in Tables 5 and 6 were left to stand at room temperature for 24 hours and visually observed for the presence or absence of separation. In the tables, those that were stable without separation were indicated with "O", and those that separated were indicated with "X".

[0164] (Viscosity measurement) The viscosity (30°C) of the hair conditioners shown in Tables 5 and 6 was measured using a B-type viscometer (Toki Sangyo Co., Ltd., TVB-10) with a spindle of "TC" at 10 rpm for 1 minute when the viscosity was 10,000 mPa·s or more, and using a BM-type viscometer (Toki Sangyo Co., Ltd., TV-10) with a rotor of "No. 3" at 12 rpm for 1 minute when the viscosity was less than 10,000 mPa·s.

[0165] (Evaluation of non-stickiness after drying) Evaluation procedure 1.30 g of Japanese tresses are washed with the plain shampoo shown in Table 1 and soaked in 15.0 g of water. 2. Apply 1mL of each of the hair conditioners shown in Tables 5 and 6, massage with your hands, leave on for 30 seconds, and then rinse for 15 seconds. 3. After towel drying and drying with a hair dryer, five expert panelists evaluated the lack of stickiness after drying using the evaluation criteria shown below.

[0166] [Evaluation Criteria] 1 point: Sticky 2 points: slightly sticky 3 points: Neither 4 points: Not very sticky 5 points: Not sticky

[0167] (Method for evaluating the durability of conditioning effect on wet hair after the first wash) Pretreatment A hair coloring agent (liquid 1 shown in Table 2 and liquid 2 shown in Table 3 mixed at a ratio of 1:1.5) was applied to 30 g of Japanese hair tresses in a bath ratio of 1:1, left for 5 minutes, and then washed off.

[0168] Evaluation procedure 1. After the above pretreatment, 30 g of Japanese hair tress was washed with the plain shampoo shown in Table 1, rinsed, and soaked in 15.0 g of water. 2. 1 mL of each of the hair conditioners shown in Tables 5 to 6 was applied, massaged into the hair with the hands, left on for 30 seconds, and then rinsed for 15 seconds. 3. After towel drying and drying with a hair dryer, the hair was washed for 30 seconds by rubbing the front and back 20 times with 1mL of plain shampoo shown in Table 1, and then rinsed for 15 seconds. Then, 1mL of plain rinse shown in Table 4 was applied for 30 seconds, and rinsed for 15 seconds. 4. The tresses were thoroughly detangled with a brush and then the moisture content was adjusted to 15g. 5. The combing force when combing 30 times with a brush at a constant speed (once per second) was measured using the dynamic combing force method (Suzuki et al.; J. Soc. Cosmet. Chem. Japan. Vol. 27, No.1, pp. 11-13, 1993), and the average of the 30 measured values ​​(maximum value) was calculated and used as an index for evaluating the durability of the conditioning effect. The smaller the combing force value, the easier and smoother the combing.

[0169] (Method for evaluating the durability of conditioning effect on wet hair after 3 washes) Except for repeating step 3 of the evaluation procedure three times in total, the combing force was measured and the evaluation was performed in the same manner as in the above "Method for evaluating the durability of conditioning effect on wet hair immediately after treatment."

[0170] In addition, the combing force of tresses when a plain rinse shown in Table 4 was used as the hair conditioner in step 2 above is shown in each table as a reference example.
