Description

  The present invention relates to a hair cleansing composition containing a specific cationic / amphoteric polymer.

  In general, a hair cleanser composition, such as a shampoo, contains a surfactant to remove hair stains. In some cases, the surfactant is used in an increased amount from the viewpoint of ensuring sufficient detergency, or a surfactant having a strong detergency is used. However, in that case, although sufficient detergency can be secured, there is a problem that the hair is squeezed and easily entangled, and the finger passage is deteriorated.

  Therefore, conventionally, a hair cleanser composition disclosed in Patent Document 1 is known. Patent Document 1 discloses a cation / amphoteric polymer (methacryloylethyldimethylbetaine / methacryloylethyltrimethylammonium chloride / methoxypolyethylene glycol methacrylate) copolymer (display name: Polyquaternium-49 (Japanese Cosmetic Display Name Dictionary, Yakuji Nippo, 2007). )) Is known to be incorporated into shampoo compositions. Such cationic / amphoteric polymers impart a conditioning effect to the hair.

In addition, you may change the said embodiment as follows.
The hair cleaning composition of the above embodiment includes a rinse-in shampoo, a scalp shampoo and the like in addition to a hair shampoo.

  -The hair cleansing composition of the above-mentioned embodiment is sufficient if each component is present at the time of use, and a part of each component contained in each agent constituting the above-described hair cleaning composition is used as a separate agent. May be saved.

Next, the embodiment will be described more specifically with reference to examples and comparative examples. In addition, this invention is not limited to the structure as described in the Example column.
A hair cleaning composition containing each component shown in Tables 1 and 2 was prepared. The numerical value in the column which shows each component in Table 1, 2 shows content of the component of the said column, The unit is the mass%. First, straight human hair wigs (hereinafter, simply referred to as wigs) were prepared, and the wigs were decolorized once with a decoloring agent (manufactured by Hoyu Corporation, Promaster EX LT), washed with water, and then dried. The wig decolored by this operation was used as an evaluation wig. Using the wig for evaluation, the hair cleansing composition of each formulation was evenly applied to the whole, the wig was swallowed and foamed, and then washed with water. After towel drying, it was dried with a dryer. The foaming and foam quality during shampooing and the feel during rinsing were evaluated according to the following criteria. The feel after finishing the wig was evaluated according to the following criteria. In addition, the notation of A, B, C, C1 in the “component” column in the table indicates a compound corresponding to each component described in the claims of the present application. The notation of “a, b” in the “component” column in the table indicates the comparative compound described in the claims of the present application.

(Bubbles)
Five panelists visually evaluated the amount of foaming according to the following criteria. Good when the amount of foaming is large (4 points), acceptable when the amount of foaming is slightly high (3 points), slightly poor when the amount of foaming is slightly small (2 points), poor when the amount of foaming is small (1) 4 points), the average value is calculated for each paneler's scoring result, 3.6 points or more are “good: 4”, 2.6 points or more and less than 3.6 points are “possible: 3”, The evaluation result was 1.6 points or more and less than 2.6 points as “slightly poor: 2” and less than 1.6 points as “defective: 1”.

(Foam quality)
Five panelists evaluated foam quality according to the following criteria. The elasticity of the foam (smooth foam) was scored in four stages: good (4 points), good (3 points), slightly bad (2 points), and bad (1 point), and the average score for each panel The value is calculated, “Good: 4” for 3.6 points or more, “Yes: 3” for 2.6 points or more and less than 3.6 points, “Slightly poor: 2” for 1.6 points or more and less than 2.6 points ”And less than 1.6 points were“ defects: 1 ”, and the evaluation results were obtained.

(Rinse feel)
About the touch of the hair when the hair cleaning composition adhering to the wig was rinsed with water, five panelists judged based on the following criteria. No squeaky feeling at the time of rinsing, scoring in 4 stages of good (4 points), good (3 points), slightly bad (2 points) and bad (1 point), and calculating the average value for the scoring results of each panel 3 .6 points or more are “good: 4”, 2.6 points or more and less than 3.6 points are “possible: 3”, 1.6 points or more and less than 2.6 points are “slightly poor: 2”, and 1.6 The score less than the point was defined as “Bad: 1”, and the result was evaluated.

(Feel after finishing)
About the feel of the hair after the completion of the hair washing and drying treatment, five panelists judged based on the following criteria. The feeling of unity of hair was scored in 4 stages: good (4 points), good (3 points), slightly bad (2 points), and bad (1 point), and the average value was calculated for the scoring results of each panel. .6 points or more are “good: 4”, 2.6 points or more and less than 3.6 points are “possible: 3”, 1.6 points or more and less than 2.6 points are “slightly poor: 2”, and 1.6 The score less than the point was defined as “Bad: 1”, and the result was evaluated.

As shown in Tables 1 and 2, it was confirmed that each example has the above result for each evaluation item. As shown in Table 2, Comparative Example 1 that does not contain the component (A) with respect to the configuration of Example 2 is inferior in evaluation of foaming, foam quality, and feeling of rinsing with respect to each Example. confirmed. It was confirmed that the comparative example 2 which does not contain the component (A) with respect to the configuration of Example 3 is inferior in the evaluation of the feeling particularly at the time of rinsing with respect to each Example. It was confirmed that the comparative example 3 which uses (a) polyquaternium-48 instead of (A) component is inferior in evaluation of especially foaming, foam quality, and the feeling at the time of a rinse with respect to each Example. It was confirmed that the comparative example 4 which uses (b) dimethicone instead of (B) component was especially inferior in foaming and foam quality with respect to each Example.

<Prescription example of hair cleaning composition>
The hair cleanser compositions of Formulation Examples 1 to 3 shown in Tables 4 to 6 below were prepared. In the same treatment method as in Example 1, a hair washing treatment was performed. As a result, it was confirmed that the same evaluation as each example was obtained.

Next, the technical idea that can be grasped from the above embodiment and other examples will be described below. Furthermore, the said hair-cleaning agent composition containing at least 1 type chosen from an amino acid type anionic surfactant and a cationic polymer.
