Description

  The present invention relates to a shampoo composition. ADVANTAGE OF THE INVENTION According to this invention, while being excellent in the scalp and scalp detergency, it is possible to moisturize the scalp after shampooing. Furthermore, the shampoo composition of the present invention has an excellent conditioning effect and can impart a smooth finish to the hair.

  In general, shampoo bases include alkyl sulfate esters, polyoxyethylene (hereinafter sometimes referred to as POE) alkyl ether sulfates, POE alkyl ether acetates, alkyl sulfosuccinates from the standpoint of detergency and foaming properties. Anionic surfactants such as salts, sulfosuccinic acid POE alkyl salts, alkyl ether phosphate salts, and N-acyl amino acid salts are used. Moreover, an amphoteric surfactant and / or a hydrophilic nonionic surfactant are blended from the viewpoints of safety, foaming power, foam sustainability, and the like.

However, anionic surfactants and amphoteric surfactants and / or hydrophilic nonionic surfactants can remove stains on hair and scalp, but oil stains or horn plugs on scalp pores. It was difficult to remove the hair, and the scalp after shampooing was moistened and the conditioning effect on the hair after shampooing could not be obtained.
Various approaches have been made and proposed in order to give the shampoo base a conditioning effect on the hair after shampooing. For example, blending a cationized polymer such as cationized cellulose or cationized guar gum (Patent Documents 1, 2, and 3), blending a silicone compound (Patent Documents 4 and 5), or a detergent component and Attempts have been made to adjust a specific water-soluble polymer to a specific pH range (Patent Document 6).

  In addition, shampoo compositions containing dicarboxylic acid esters have been proposed to remove horn plugs of the scalp (Patent Documents 7 and 8). Furthermore, a shampoo composition has been proposed that can remove sebum and dirt clogged in the pores of the scalp and can give a smooth finish to the washed hair (Patent Document 9).

JP-A-3-188016 JP-A-11-236320 JP-A-4-36226 JP-A-7-277931 JP-A-4-234309 JP 2006-298916 A Japanese Patent Laid-Open No. 10-120532 JP 2009-96778 A Japanese Patent Laid-Open No. 2007-1889

  Recent shampoo compositions not only remove dirt on the hair and scalp as described above, but also oils often used in scalp cosmetics and hair cosmetics, and sebum clogged in scalp pores, etc. There is a demand for a cleaning effect that can remove the water. Further, a conditioning effect is expected that moisturizes the scalp after the bangs and gives the hair a supple and smooth finish. However, at present, it is difficult to say that a shampoo for scalp and hair that can be fully satisfied by the user is provided.

For example, although the shampoos described in Patent Documents 1 to 6 have a conditioning effect, they are not sufficient in removing oil stains on the scalp and removing oil stains and square plugs clogged in the scalp pores. Further, the silicones used in the shampoos described in Patent Documents 4 and 5 are difficult to remove due to the properties of silicones, and if they remain after washing the hair, the hair dye is used when the hair dye is used. It is thought to adversely affect the effect.
Furthermore, the shampoos described in Patent Documents 7 and 8 are effective in removing oil stains on the scalp and oil stains and horn plugs clogged in the scalp pores, but foaming is insufficient and after washing the hair. The conditioning effect is not enough. Moreover, the cleaning power of the shampoo described in Patent Document 9 is not sufficient to remove commonly used silicones.

  Thus, it is difficult for conventional shampoos to achieve both the removal of oil stains and horn plugs in the scalp pores and the conditioning effect after shampooing. The use of shampoo has become the mainstream. That is, there is no shampoo that sufficiently satisfies the scalp and hair scrubbing effect and the conditioning effect after the hair washing, resulting in the consumer having to work twice.

  Accordingly, an object of the present invention is to provide a shampoo composition that is excellent in scalp and scalp detergency and that can impart a moisturizing and conditioning effect to the scalp after shampooing. More specifically, it has a detergency that removes oils containing silicone that is excellent in foaming and hard to clean on the scalp and hair, dirt from the environment or inside the human body, and horn plugs clogged in the scalp pores. It is intended to provide a shampoo composition for scalp and hair, which has an excellent conditioning effect to moisturize the scalp after shampooing and to give the hair after shampooing a supple and smooth finish.

As a result of intensive research on the shampoo composition capable of solving the above problems, the present inventors have surprisingly found that an anionic surfactant, a nonionic surfactant having an HLB value of 6 or less, and a cation It has been found that a shampoo composition containing a functional polymer can sufficiently clean the scalp and hair and can give a smooth finish to the hair.
The present invention is based on these findings.

<< Examples 1-4: Low viscosity transparent shampoo >>
In Examples 1 to 4, low-viscosity transparent shampoos were produced. A low-viscosity transparent shampoo having the composition shown in Table 1 was prepared according to a conventional method. The obtained low-viscosity transparent shampoo was evaluated for a “foamability test” and a “use feeling (sensory test)”. The results are shown in Table 1.

<< Comparative Examples 1-3: Low viscosity transparent shampoo >>
A low-viscosity transparent shampoo having the composition shown in Table 1 was prepared according to a conventional method. About the obtained low-viscosity transparent shampoo, "use feeling" was evaluated. The results are shown in Table 1.

  When the value of the weight ratio (b) / (a) of the components (a) and (b) increases from 0.003 to 0.008, the usability (foaming (foaming), hair washing, scalp washing , Moisturized scalp after drying, and hair feel after drying). Moreover, when the value of (b) / (a) is reduced from 0.125 to 0.83, the foaming property (foaming) is improved, and the moisture of the scalp after drying and the hair feel after drying are also improved. . In particular, scalp scrubs that were evaluated as “very good (」) ”were also excellent in removing horn plugs.

<< Examples 5 to 8: Highly viscous transparent shampoo >>
In Examples 5 to 8, high-viscosity transparent shampoos were produced. A highly viscous transparent shampoo having the composition shown in Table 2 was prepared according to a conventional method. About the obtained highly viscous transparent shampoo, "usability (sensory test)" was evaluated. The results are shown in Table 2.

<< Example 9: Pearly cloudy shampoo >>
In Example 9, a pearly cloudy shampoo was produced. Pearl-like cloudy shampoos having the compositions shown in Table 3 were prepared according to a conventional method. About the obtained pearl-like cloudy shampoo, "usability (sensory test)" was evaluated. The results are shown in Table 3.

  The shampoo composition of the present invention can remove oil stains on the scalp and oil stains and horn plugs clogged in the pores of the scalp. Further, the scalp after the bangs is sufficiently moisturized and has an excellent conditioning effect, and can give a supple and smooth finish to the hair. Therefore, it is possible to obtain a sufficient scalp and hair scrubbing effect and a conditioning effect after the hair scrubbing without using two scalp cleaning agents and shampoos.
