Description

Technical Field

[0001] The present invention relates to hair cleansing compositions. Background Art

[0002] In recent years, there has been a demand for hair cleansing compositions that have good foam properties (foam density, foaming, foam smoothness, etc.) and can achieve good hair quality (no stickiness, fluffy feeling, manageability, etc.) after washing and drying.

[0003] For example, in order to provide a shampoo having a conditioning effect, a composition containing a cationized polysaccharide such as cationized cellulose and cationized guar gum, and a silicone composition has been proposed (for example, see Patent Documents 1 to 2). The cationized polysaccharide and silicone composition contained in the hair cleansing composition improves the volume of the hair after washing and drying, and as the amount thereof is increased, the manageability of the hair after washing and drying is also improved. On the other hand, when the amount of the cationized polysaccharide and silicone composition in the hair cleansing composition is increased, there is a case where a strong sticky feeling remains and the volume of the hair after washing and drying decreases. That is, the manageability of the hair after washing and drying and the volume of the hair after washing and drying have a trade-off relationship, and it is difficult to achieve both.

[0004] Therefore, it is desired to provide a hair cleansing composition which has excellent foam performance (foam density and foaming) and excellent volume and manageability of hair after washing and drying.

[0156] <Evaluation of the manageability of hair after washing and drying>

[0157] After drying the hair bundles that had been chemically treated (perming once and bleaching twice) at 25°C and 80% RH overnight, the width of the hair bundles was measured and taken as the initial hair bundle width. After that, the hair was washed 7 times with 1 g of each hair cleansing composition and dried again at 25°C and 80% RH overnight. The width of the hair bundles after drying was measured and taken as the post-treatment hair bundle width. The change rate of the post-treatment hair bundle width was calculated when the initial hair bundle width was set to 100%, and the judgment was made based on the following judgment criteria.

[0158] It should be noted that the number of samples was 3, and the determination was made based on the average value of the obtained change rates.

[0165] <Evaluation of the volume of hair after washing and drying>

[0166] Hair bundles that had been chemically treated (permed once, bleached twice) were washed 7 times with 1 g of each hair cleansing composition and dried overnight at 25°C 80% RH. The fluffy feeling of the dried hair bundles was evaluated based on the following criteria. It should be noted that the number of samples was 3, and the total score of each evaluation value obtained was calculated and evaluated based on the following criteria.

[0196] Industrial Applicability

[0197] The hair cleansing composition has excellent foam density and foaming properties, and provides excellent volume and manageability of the hair after washing and drying. Therefore, it can be widely used as a bath hair care agent such as shampoo, shampoo-in-one shampoo, conditioning shampoo, and treatment shampoo.
