Description

Hair cleansing composition {HAIR CLEANSING COMPOSITION}

The present invention relates to a hair cleanser composition which is excellent in the speed of foaming and elasticity of foam, has good fingertip property at the time of rinsing, and can impart moistness after drying.

When the hair is shampooed or rinsed when using shampoo, the hair tangles to each other, so that the ends of the hair may be split or cracked. In addition, not only when using shampoo, but also depending on the state of hair after drying, the degree of entanglement of the hair varies, and when the hair is in a bust state, the end of the hair is cracked or thermosensitivity is likely to occur. Therefore, as a method for suppressing the entanglement of hair, the speed of foaming and the elasticity of bubbles are required at the time of shaving, the fingertip property is required at the time of rinsing the hair, and the hair after drying does not bust, . The effect of finger passage at the time of rinsing may be insufficient for the hair that appears to be curled up by applying chemical treatment such as perming treatment or hair color treatment, Sex is required. In addition, the moisturization after drying of the hair is remarkable in that moisture loss of the hair is remarkable and the effect is hardly obtained at the time of drying in the winter when the cuticle is prone to damage, and a sufficiently moist feeling is required even in such an environment.

As described above, it is important to sufficiently suppress the entanglement of the hair in the course of washing before and after the washing, rinsing, and drying, in order to maintain the hair dryness.

Recently used shampoos tend to be autologous in the background of natural orientations spread among consumers. In such a shampoo, the amino acid-based surfactant has been used as a cleansing component of low irritation, and it has become mainstream. However, although the amino acid surfactant has an advantage that the irritation is low, the rate of foaming and the elasticity of the foam are inferior to those of conventional sulfuric acid ester surfactants such as polyoxyethylene alkyl sulfate. Particularly, when washing hair, for example, hot water of about 40 캜 is used, so that the generation of foam tends to be slowed and the elasticity of the foam tends to be weakened. The speed of bubble generation and the elasticity of bubbles are important in terms of reducing the entanglement of hair at the time of hair frying, and the hair ends are cracked or inhibited. Therefore, attempts have been made to improve the bubble performance by combining amino acid surfactants ought.

For example, Patent Document 1 exemplifies a composition comprising acyl methyl taurine salt, acyl alanine salt, and amphoteric surfactant in combination. In this composition, although the speed of foam generation at the time of drawing is good, the elasticity of the foam is not satisfactory. As a technique for improving the elasticity of the foam, a method of adding a polymer component such as a cation polymer is known, but there has been a problem in that bubble generation at the initial stage of the tincture is slowed down. For this reason, it has been difficult to develop a shampoo which has a fast bubble generation and a bubble resilience by a method of simply combining an amino acid surfactant or a combination with a polymer component.

On the other hand, as a method for improving the finger-passing property at the time of rinsing, there is known a method of forming lubricating particles (coacervate) at the time of rinsing with three components of an amino acid surfactant, an amphoteric surfactant and a cationic polymer. For example, Patent Document 2 discloses a technique in which a specific compound is blended with these three components to improve the finger-passing property at the time of rinsing the shampoo. For example, in Patent Document 2, an alkylmethyl taurine salt, an amphoteric surfactant, Dihydroxypropyl) amine. ≪ / RTI > This composition improves the fingertip property at the time of rinsing, but the moistness of the hair after drying is not always satisfactory. In addition, although the elasticity of the foam is good, the rate of foam generation is not sufficient.

As another example using an amino acid-based surfactant, Patent Document 3 exemplifies a composition containing an acyl hydroxyalkyl beta alanine salt, sodium polyoxyethylene (2.5) lauryl ether sulfate and cationic cellulose. This composition improved the moistness of the hair after drying, but it was not always sufficient and the fingertip property at the time of rinsing was unsatisfactory. Also, although the speed of bubble generation is good, the elasticity of the bubble is not sufficient.

As another example of improving the moisturization after hair drying, Patent Document 4 exemplifies a composition comprising an acyl methyl taurate salt, an amphoteric surfactant, and a cationic polymer with soybean lecithin and a collagen hydrolyzate. This composition improved the moistness of the hair after drying, but the fingertip property at the time of hair rinsing was not necessarily sufficient. In addition, although the elasticity of the foam is good, the rate of foam generation at the time of trimming is not sufficient.

As described above, the method of simply combining the amino acid surface active agent and the method of combining with the other components is advantageous in that bubbles are generated rapidly, the foam has elasticity (elasticity), the fingertip property at the time of rinsing is good, It has been difficult to develop a shampoo which can impart moisturization after drying.

In Comparative Example 5, since the component (c) was not contained, the fingertip property at the time of rinsing was insufficient.

In Comparative Example 6, since the component (d) was not contained, the fingertip property at the time of rinsing was insufficient.

Comparative Example 7 contained polyoxyethylene (2.5) lauryl ether sodium sulfate in place of the component (b), and although the rate of foaming was good, the elasticity of the foam, the fingertip property at the time of rinsing, All of the moisture was insufficient.

In Comparative Example 8, since the cocoylalanine sodium was contained instead of the component (a), the elasticity of the foam, the fingertip property at the time of rinsing, and the moisturization after drying were insufficient, though the rate of foaming was good.

Comparative Example 9 contained sodium cocoyl glutamate in place of the component (a), so that the finger penetration property at the time of rinsing and the moisturization after drying were good, but both the rate of foam generation and the elasticity of the foam were insufficient.

In Comparative Example 10, the component (a) was not contained, and as the other component, alkyl dihydroxypropylamine was contained for the purpose of improving the finger penetration property during rinsing. However, although the fingertip property and the foam elasticity at the time of rinsing are good, both the rate of foam generation and the moisture content after drying are insufficient.

Comparative Example 11 contains soybean lecithin and collagen hydrolyzate in order not to contain the component (a) but as the other component to finish with smooth and moist hair. However, although the elasticity of the foam and the moisturization after drying are good, both the rate of foam generation and the fingertip property at the time of rinsing are insufficient.
