Description

The present invention provides a shampoo composition having smooth finger passage during rinsing, no sliminess, and excellent softness after rinsing.

In recent years, habits such as hair color, perm, and bleach have become widespread regardless of generation or gender, and hair is constantly exposed to chemical stimuli. Therefore, it is important to have a component that prevents the surface and inside of the hair from being damaged and getting caught when washing the hair. Many conditioning components have been developed to prevent catching during hair washing, and cationic polymers include cationized celluloses, cationized polysaccharides, and silicones. These serve as a conditioning agent and can cover the surface of the hair to reduce the catching of the hair and wash the hair.

In addition, there is an amino acid-based activator as an activator that enhances the conditioning property by combining with a cationic polymer. Amino acid-based activators are used as activators with high conditioning properties because they are more likely to form coacervates, which are complexes with cationic polymers, as compared with conventional laureth sulfate-based activators.

In recent years, the use of amino acid-based activators in shampoo preparations has become widespread because it has the effect of suppressing squeaks when washing hair. Therefore, there are many shampoos that combine an amino acid-based activator with cationized cellulose or cationized guar gum to have high hair conditioning properties (Patent Document 1). It has also been reported that by using an amino acid-based activator as the main ingredient of shampoo, the conditioning property at the time of washing hair is further enhanced (Patent Document 2).

However, while the combination of an amino acid-based activator and a cationic polymer improves the conditioning property of the hair, the coacervate may adhere to the hair too much, and the hair may become stiff during rinsing or hard after rinsing. rice field.

As the component (C), it is preferable to use two or more types of cationized cellulose having different degrees of cationization. By combining two or more types of cationized cellulose having different degrees of cationization, it is possible to reduce the squeaky feeling during washing and to obtain a soft feel to the hair after rinsing. For example, a formulation with a cationization degree of 0.6 to 1.1 meq / g cannot reduce the squeaky feeling during hair washing, and a formulation with a cationization degree of 1.2 to 1.5 meq / g after rinsing. My hair gets stiff. Therefore, it is preferable to blend two or more types of cationized cellulose having different degrees of cationization in a specific ratio.

Specifically, the cationized cellulose having a degree of cationization of 0.6 to 1.1 meq / g (hereinafter, (c1)) and the cationized cellulose having a degree of cationization of 1.2 to 1.5 meq / g (hereinafter, (hereinafter,). c2)) is combined.

The degree of cationization was calculated from the following formula. “Meq / g”, which is a unit of the degree of cationization, indicates the number of milliequivalents of cation groups per 1 g of a sample.
Degree of cationization (meq / g) = (number of moles of cationized glucose unit in 1 g of polymer compound) × 1000
Number of moles of cationized glucose unit in 1 g of polymer compound = (nitrogen content in polymer compound) / (atomic weight of N)

The degree of cationization of cationic cellulose can be easily calculated if the chemical structure is clear, but even when the structure such as the monomer ratio is unknown, the measured value of the N content by the Kjeldahl method or the like. Can be calculated from. The degree of cationization shown in the present invention was calculated based on the value measured by the second method of nitrogen quantification method, which is a general test method based on the cosmetic raw material standard, which is the Kjeldahl method.

The blending ratio of the component (c1) and the component (c2) is preferably (c1) / (c2) = 0.35 to 0.55. When the blending ratio is 0.35 or more, the softness of the hair can be obtained after rinsing, and when it is 0.55 or less, the smoothness at the time of rinsing is good.

Further, it is preferable that the total amount of (C), which is a combination of (c1) and (c2), is 0.6% by mass or less based on the total mass. When it is 0.6% by mass or less, the softness of the hair after rinsing is good.

(D) Cationized galactomannan In the present invention, the cationized galactomannan is used for the purpose of imparting softness to the hair after rinsing, and one kind or two or more kinds can be appropriately selected and used. Examples of the cationized galactomannan include cationized guar gum, cationized tara gum, cationized locust bean gum, and cationized fenugreek gum.

From the viewpoint of smoothness during rinsing, guar hydroxypropyltrimonium chloride, which is a cationized guar gum, is preferable. Specific examples of commercially available products include Katinal CG-100S (Toho Chemical Industry Co., Ltd.), JAGUAR EXCEL (Solvay Nikka Co., Ltd.) and the like.
