Description

Technical Field

[0001] The present invention relates to a hair cleansing composition.

Background Art

[0002] In recent years, there has been a demand for a hair cleansing composition that has good foam performance (such as foam density, foaming, and smoothness of foam), and can achieve good hair quality (lack of stickiness, smoothness, and good coherence, etc.) after washing and drying.

[0003] For example, for the purpose of providing a shampoo having a conditioning effect, compositions containing cationized polysaccharides such as cationized cellulose and cationized guar gum, and silicones have been proposed (see, for example, Patent Documents 1 and 2). The cationized polysaccharides and silicones contained in the hair cleansing composition improve the smoothness of the hair after washing and drying, and also improve the good coherence of the hair after washing and drying as the blending amount increases. On the other hand, when the blending amount of the cationized polysaccharides and silicones in the hair cleansing composition increases, stickiness remains strong, and the smoothness of the hair after washing and drying may decrease. That is, the good coherence of the hair after washing and drying and the smoothness of the hair after washing and drying are in a relationship similar to a trade-off, and it has been difficult to achieve both.

[0004] Therefore, it is desired to provide a hair cleansing composition that is excellent in foam performance (foam density and foaming), and is excellent in smoothness and good coherence of the hair after washing and drying.

Examples

[0057] Hereinafter, the present invention will be specifically described with reference to Examples and Comparative Examples, but the present invention is not limited to these Examples at all. The content of each component described in the Examples and Comparative Examples is shown in "mass%", the total amount is 100% by mass, and all are values converted to pure components.

[0058] (Examples 1 to 31 and Comparative Examples 1 to 9) The hair cleansing compositions having the compositions and contents shown in Examples 1 to 31 and Comparative Examples 1 to 9 were prepared according to the following method. Specifically, the component (B) and purified water were uniformly mixed at 60°C to 70°C and expanded, and then the component (A) was uniformly mixed. Thereafter, a small article in which the component (C) or the comparative component (C) was uniformly dispersed with the component (D) was added, uniformly mixed and expanded. Thereafter, after cooling to 40°C or lower, other components (phenoxyethanol, POE(2) monolaurylamide, citric acid, fragrance) were uniformly mixed to obtain each hair cleansing composition. In addition, the mixing of each component was performed by using a propeller as a stirring blade and stirring using a three-one motor (HEIDON BL1200, manufactured by Shinto Kagaku Co., Ltd.).

[0059] For each of the hair cleansing compositions of Examples 1 to 31 and Comparative Examples 1 to 9, "foaming ability", "foam density", "cohesion of hair after drying", and "smoothness of hair after drying" were evaluated and determined as follows. The results are shown in Tables 1 to 4 below.

[0060] <Evaluation of foaming ability and foam density> Five professional panelists used 6 g or 3 g of each hair cleansing composition according to the hair length for 2 days (once a day). At the time of washing on the second day, "foaming ability" and "foam density" were evaluated based on the following evaluation criteria. The results were obtained by summing the total scores of five professional panelists and determined based on the following determination criteria. - Evaluation criteria for foaming ability - 5 points: Foaming is very fast and a sufficient amount of foam can be obtained. 4 points: Foaming is fast and a sufficient amount of foam can be obtained. 3 points: Foaming is slightly slow, but a sufficient amount of foam can be obtained. 2 points: Foaming is slow and a sufficient amount of foam cannot be obtained. 1 point: No foaming at all. - Evaluation criteria for foam density - 5 points: The foam is very dense. 4 points: The foam is dense. 3 points: The foam is slightly dense. 2 points: The foam is not very dense. 1 point: The foam is not dense. - Criteria for judging foaming and foam density - ◎◎: 23 to 25 points ◎ : 19 to 22 points ○ : 16 to 18 points △ : 13 to 15 points × : 12 points or less

[0061] <Evaluation of the cohesion of hair after washing and drying> A tuft of chemically treated (one perm and two bleaches) hair was dried overnight at 25°C and 80% RH, and then the width of the hair tuft was measured as the initial hair tuft width. Subsequently, each hair cleansing agent composition (1 g) was used for washing 7 times, and then dried overnight at 25°C and 80% RH again. The width of the hair tuft after drying was measured as the hair tuft width after treatment. The change rate of the hair tuft width after treatment was calculated with the initial hair tuft width as 100%, and the judgment was made based on the following criteria. Note that the number of samples was 3, and the judgment was made based on the average value of the obtained change rates. - Criteria for judging the cohesion of hair after drying - ◎◎: Less than 90% ◎ : 90% or more and less than 95% ○ : 95% or more and less than 100% △ : 100% or more and 105% or less × : Exceeding 105%

[0062] <Evaluation of the smoothness of hair after washing and drying> A tuft of chemically treated (one perm and two bleaches) hair was washed 7 times using 1 g of each hair cleansing agent composition and dried overnight at 25°C and 80% RH. The smoothness of the hair tuft after drying was evaluated based on the following evaluation criteria. Note that the number of samples was 3, the total score of the obtained evaluation values was determined, and the judgment was made based on the following criteria. - Evaluation criteria for the smoothness of hair after washing and drying - 5 points: Very smooth 4 points: Smooth 3 points: Slightly rough 2 points: Slightly feels like tufts of hair 1 point: Feels like tufts of hair - Criteria for judging the roughness of hair after washing and drying ◎◎: 23 points or more and 25 points or less ◎ : 19 points or more and 22 points or less ○ : 16 points or more and 18 points or less △ : 13 points or more and 15 points or less × : 12 points or less

Industrial Applicability

[0072] Since the hair cleansing composition is excellent in foam density and foaming, and excellent in the smoothness and good cohesion of the hair after washing and drying, it can be widely used, for example, as an in-bath hair care agent such as shampoo, rinse-in shampoo, conditioning shampoo, treatment-in shampoo, etc.
