Abstract

PROBLEM TO BE SOLVED: To provide a hair washing composition that is excellent in foam volume and foam quality, prevents even damaged hair from becoming entangled during rinsing with a smooth texture, suppresses the occurrence of static electricity even under dry conditions such as in the winter, and can improve hair setting properties.SOLUTION: A hair washing composition comprises following components (A)-(F): (A) ether sulfuric acid salt type surfactant; (B) ether carboxylic acid salt type surfactant; (C) cationic cross-linked vinyl copolymer; (D) polypropylene glycol; (E) cationized polysaccharide; and (F) water.

Description

  The present invention relates to a hair cleansing composition.

  As hair colors and perms become more widespread, hair damage has become a major concern for consumers. Hair damage increases the friction between the hairs and appears as tangling of the hair during shampooing and drying, a decrease in the gloss of the hair, and deterioration of cohesiveness.

  In general, an anionic surfactant and a cationic polymer are blended in a shampoo, and these form a complex (coacervation) upon rinsing, thereby giving the hair a slipperiness and a conditioning component on the hair. Are left behind. However, the effect is not sufficient because the formed complex is difficult to be adsorbed to the hair tips where damage has accumulated. In contrast, the combined use of an ether carboxylate type surfactant, an ether sulfate type surfactant and a specific cationic cross-linked vinyl copolymer improves foaming and improves fingering during rinsing. Techniques are known (see, for example, Patent Documents 1 to 3).

JP 2008-285437 A JP 2010-070529 Gazette JP 2009-235059

  Damaged hair has high friction on the hair surface and is easily charged with static electricity by brushing. In particular, the troubles under dry conditions such as winter are mainly because the hair does not settle due to the influence of static electricity.

  Therefore, in order to reduce the damage concerns of these consumers, it is possible to wash the hair comfortably while protecting the entire hair with a sufficient amount of foam and excellent foam quality. Development of shampoo technology that suppresses the generation of static electricity is expected. However, in the techniques of Patent Documents 1 to 3, the generation of static electricity under dry conditions cannot be suppressed, and the foam quality and smoothness at the time of rinsing are not sufficient.

  Therefore, the present invention is excellent in the amount of foam and the quality of foam, and even when damaged hair is tangled, it feels smooth without touching, and also suppresses the generation of static electricity even under dry conditions such as winter, and the hair cohesiveness The present invention relates to a hair cleansing composition that can improve hair quality.

  The present inventors use the ether sulfate salt type surfactant, the ether carboxylate type surfactant, and the cationic crosslinked vinyl copolymer together with polypropylene glycol and cationized polysaccharide to satisfy the above requirements. It has been found that a cleaning agent can be obtained.

The present invention provides a hair cleansing composition containing the following components (A) to (F).
(A) Ether sulfate type surfactant
(B) Ether carboxylate surfactant
(C) Cationic cross-linked vinyl copolymer
(D) Polypropylene glycol
(E) Cationized polysaccharide
(F) Water

  Furthermore, this invention provides the usage method of the hair cleaning composition which wash | cleans, after apply | coating said hair cleaning composition to the hair moistened well, making it adjust to the whole hair, and foaming well.

  The hair cleanser composition of the present invention is excellent in the amount of foam and foam quality (smoothness and elasticity), is tangled even when it is damaged, and feels smooth, and even under dry conditions such as winter. It can suppress the generation of static electricity and improve the unity of hair.

Examples 1-8, Comparative Examples 1-7
The shampoo compositions shown in Table 1 and Table 2 were prepared, and performance evaluation was performed according to the following methods.

(Bubble amount)
A hair tress was prepared using 25 g of hair collected from a Japanese who had not been chemically treated. After the hair tress is sufficiently moistened with tap water so that it contains approximately the same amount of water as the dry hair mass, 1 g of the shampoo composition shown in Tables 1 and 2 is applied, and both ends of the hair tress are index fingers and thumbs. Then, scissors and palms were put together and rubbed for 30 seconds. Next, the hair tress was squeezed by hand, the adhering foam was collected in a graduated cylinder, and the volume of the foam was measured.

(Foam quality)
Foam was produced in the same manner as when the amount of foam was measured. After that, three researchers conducted a sensory evaluation of foam quality from the viewpoints of elasticity, sliding, and sustainability. The evaluation results were determined according to the following evaluation criteria, and were determined after discussions between the three persons.
Evaluation criteria:
A: Strong presence of bubbles (elasticity), high lubricity, and almost no hair entanglement.
○: The presence of bubbles (elasticity), lubricity, and little tangling of hair.
Δ: Insufficient presence (elasticity) of bubbles (a lot of moisture and a feeling of bubbles crushing), or insufficient lubricity and hair entanglement.
X: Foam presence and lubricity are insufficient (equivalent to 12 mass% polyoxyethylene (1) alkyl (C10-16) ether sulfate ammonium salt (Emar 125A, manufactured by Kao Corporation) aqueous solution)

(Smoothness when rinsing)
A hair tress was prepared from 25 g (about 30 cm in length) of the hair of a person who used hair color 3-4 times a year. After the hair tress was moistened with tap water for 30 seconds, excess water was removed by squeezing the hair by hand until the moisture content of the hair became half of the dry hair weight. Next, 2.5 g of the shampoo composition shown in Tables 1 and 2 was applied to the above-mentioned tress and foamed for 30 seconds so that the hair was rubbed by hand as described above. After suspending the foamed hair tress on the force gauge, while applying tap water at a flow rate of about 2170 mL / min in the shower, sandwich the hair tress with the two hair brushes from the front and back or from both sides, and perform combing 30 times. Such force was measured. As the measuring apparatus, the one described in J. Soc. Cosmet. Chem. Japan. Vol. 27, No. 1, P11-13 1993 was used. Combing was performed at a rate of about 1 per second. Of the measured combing force, the smoothness was evaluated by the average value of 25 times excluding the first 5 times. In addition, Kao Lunet (full length: about 20 cm, comb part size: about 4 × 10 cm, comb tooth density: 6 / cm) was used as the hair brush.

(Static charge)
A hair tress was prepared from 20 g (about 30 cm in length) of the hair of a person who used hair color 3-4 times a year. After the hair tress was moistened with tap water for 30 seconds, excess water was removed by squeezing the hair by hand until the moisture content of the hair was about ½ of the dry hair weight. Next, 2.0 g of the shampoo composition shown in Tables 1 and 2 was applied to the above-mentioned tress and foamed for 30 seconds so that the hair was rubbed by hand as described above. Thereafter, the hair tress was rinsed for 30 seconds under running water, and finally the hair was dried with a hand or finger and dried for 5 minutes. After drying, the amount of static electricity on the hair surface in a laboratory atmosphere (22 ° C., 24% RH) was measured using an electrostatic meter YC-102 (Azpure).
