Description

  The present invention relates to a hair cleansing composition that is excellent in the speed of foaming and the firmness of foam, and can impart a sense of unity and smoothness to the hair after drying.

When hair is rinsed or rinsed when using shampoo, the hair may be entangled and damaged, resulting in split ends and split hairs. At this time, the foam at the time of shampoo has a role to reduce the entanglement between the hairs, the foaming is fast, the foam quality is fine, and the foam with elasticity is important. In addition, not only when using a shampoo, but also the ease of entanglement of the hair varies depending on the hair condition after drying. For example, when setting hair, a certain degree of smoothness is required, and when there is no smoothness, it is easy to get caught when combing hair with a comb or a finger, and split ends and split hairs are likely to be generated. Furthermore, even when the hair after setting is not settled, split ends and split hairs are easily generated, and the aesthetic appearance is also impaired. For this reason, it is important for smooth and easy to bundle after drying the hair to suppress split ends and split hairs.
As described above, suppressing entanglement of the hair during shampooing and after drying is important for maintaining the health of the hair, the foaming is fast, the foam has elasticity, and the hair feels cohesive after drying. The development of a shampoo that can give smoothness has been desired.

  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. Such shampoos are mainly composed of amino acid surfactants as low-irritant cleaning ingredients. However, although amino acid-based surfactants have the advantage of low irritation, the foaming speed and foam elasticity are inferior to those of conventional sulfate ester-type surfactants such as 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. As mentioned above, the speed of foaming and elasticity of foam are important in terms of reducing entanglement of the hair during hair washing and suppressing split ends and split hairs. So far, foam performance has been improved by combining amino acid surfactants. Attempts have been made to improve.

  For example, Patent Document 1 discloses a composition in which an acyl glutamate 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 always 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 has a fast foaming and has elasticity in the foam by simply combining the amino acid surfactants and the polymer components.

  On the other hand, as a method for improving the feeling of unity and smoothness after drying, a method of adding a surfactant having a hydroxyl group to a shampoo is known. For example, Patent Document 2 discloses a composition in which an acylmethylalanine salt and a cationic polymer are combined with a β-alanine type amphoteric surfactant. Although this composition improved the feeling of unity after drying, the smoothness after drying was not 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. This composition has improved smoothness after drying, but it is not always sufficient, and the unity feeling after drying is unsatisfactory. Moreover, although the foaming speed was good, the elasticity of the foam was not sufficient.

As an example of improving the smoothness after hair drying, Patent Document 4 discloses a composition in which an acylmethylalanine salt, an acetic acid betaine amphoteric surfactant and an inorganic salt are mixed with polyoxyalkylene fatty acid monoisopanolamide. It has been. This composition improved the smoothness after drying, but the feeling of unity after drying was 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 described above, the simple method of combining amino acid surfactants and the method of combining with other components provides quick foaming, elasticity to the foam, and imparts a sense of unity and smoothness to the hair after drying. The development of shampoos that can be difficult.
