Description

  The present invention relates to a hair cleansing composition that is excellent in the speed of foaming and firmness of foam, has good fingering properties during rinsing, and can give a moist feeling after drying.

When hair is rinsed or rinsed when using shampoo, the hairs may be entangled with each other to cause split ends or split hairs. Further, not only when using a shampoo, but also the ease of entanglement of the hair changes depending on the hair state after drying, and split hairs and split hairs are liable to occur when the hair is in a cramped state. Therefore, as a method of suppressing the entanglement of the hair, the speed of foaming and the elasticity of the foam are required at the time of shampooing, and finger rinsing properties are required at the time of rinsing the hair, and the hair after drying does not clump, resulting in a moist finish Is required. The effect of finger rinsing at the time of rinsing may be inadequate for hair that has been damaged by chemical treatment such as perm treatment or hair color treatment, and the cuticle has been turned over. Sufficient finger penetration is required even for such a hair condition. In addition, the moist feeling after drying the hair makes it difficult to obtain the effect during the dry season in winter, when the moisture loss of the hair is significant and the cuticle is susceptible to damage, and there is a need for a moist feel in such an environment. It is done.
Thus, it is important for maintaining the health of the hair to sufficiently suppress the entanglement of the hair in the process before and after washing such as washing, rinsing, and drying.

  In recent years, shampoos used in recent years tend to be favored with low irritation because of the natural orientation that is widespread among consumers. As such shampoos, those using an amino acid surfactant as a mild stimulating cleaning component are mainly used. However, although amino acid-based surfactants have the advantage of low irritation, the foaming speed and foam elasticity are inferior to those of sulfate-type surfactants such as conventional polyoxyethylene alkyl sulfates. . In particular, warm water of about 40 ° C., for example, is used for washing the hair, so that foaming tends to be slow and the elasticity of the foam tends to be weak. The speed of foaming and the elasticity of foam are important in terms of reducing the entanglement of the hair during shampooing and suppressing split ends and tears. So far, attempts have been made to improve foam performance by combining amino acid surfactants. Has been made.

  For example, Patent Document 1 discloses a composition in which an acylmethyl taurine salt, an acyl alanine salt, and an amphoteric surfactant are combined. Although this composition had good foaming speed at the time of shampooing, the elasticity of the foam was not satisfactory. Further, as a technique for improving the elasticity of foam, a method of adding a polymer component such as a cationized polymer is known, but there is a problem that foaming in the initial stage of hair washing becomes slow. For this reason, it has been difficult to develop a shampoo that is quick to foam and elastic in the foam by simply combining an amino acid surfactant or a polymer component.

  On the other hand, as a method for improving the fingering property at the time of rinsing, 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 cationized polymer is known. As a technique in which a specific compound is blended with these three components and the fingering property at the time of shampoo rinsing is improved, for example, Patent Document 2 discloses an alkyl bis having an hydroxyl group in an acylmethyltaurine salt, an amphoteric surfactant and a cationized polymer. The composition which mix | blended (dihydroxypropyl) amine is mentioned. Although this composition improved the fingering property at the time of rinsing, the moist feeling of the hair after drying was not always satisfactory. Moreover, although the elasticity of the foam was good, the speed of foaming was not sufficient.

  As another example using an amino acid-based surfactant, Patent Document 3 includes a composition containing acylhydroxyalkyl β-alanine salt, polyoxyethylene (2.5) sodium lauryl ether sulfate and cationized cellulose. ing. Although this composition improved the moist feeling of the hair after drying, it was not always sufficient, and the fingering property at the time of rinsing was not satisfactory. Moreover, although the foaming speed was good, the elasticity of the foam was not sufficient.

As another example of improving moist feeling after hair drying, Patent Document 4 includes a composition in which acylmethyltaurine salt, amphoteric surfactant, cationic polymer and soy lecithin and collagen hydrolyzate are blended. Yes. This composition has improved the moist feeling of the hair after drying, but the fingering property at the time of rinsing the hair is not always sufficient. In addition, although the elasticity of the foam was good, the speed of foaming at the time of washing the hair was not sufficient.
As mentioned above, simply combining amino acid-based surfactants and other components, the foaming is fast, the foam has elasticity, good rinsability, and after the hair is dry It has been difficult to develop a shampoo that can give a moist feeling.
