Description

  The present invention relates to a foam hair styling agent.

  Conventionally, there are hair styling agents containing various powder components for the purpose of imparting a natural light finish and texture. However, these powder components give an excellent finish and texture, but have a problem that a squeaky sensation is produced after styling and that washing off at the time of shampooing is poor.

  On the other hand, as one of hairdressing agents that can be uniformly applied to hair, there is a foamy hairdressing agent that can discharge the composition in the form of foam together with a propellant to give hairstyling. However, when a powder component is blended with these foam-like hairdressing agents, there is a problem in that they are not discharged in the form of bubbles from the initial stage. Moreover, even if it can be discharged in the form of bubbles in the initial stage, there is also a problem that if it is continuously discharged, the discharge in the form of bubbles does not continue and the liquid form is gradually discharged. Thus, it was very difficult to mix a powder component with foamy hair styling agent and to discharge a stable foam continuously.

  Until now, as an attempt to blend a powder component into a foam hairdressing agent, for example, a foam containing a specific silicone powder, a silicone oil, a polyhydric alcohol, an anionic surfactant, and a propellant. Aerosol-type cosmetics (see, for example, Patent Document 1), a specific amount of sterols, a specific amount of inorganic powder, O. A hair foam containing a liquid ester oil having a specific B value and a propellant (for example, see Patent Document 2) has been proposed.

  However, although such a trial can give the fine finish and texture peculiar to the powder component and reduce the squeaky feeling, it is inferior to fully exhibiting the desired hair styling function and stickiness. There is a problem that occurs. In addition, even in these attempts, the stability of the foam itself has not been sufficiently studied, and the continuous ejection in the form of foam is not fully satisfactory.

<Evaluation criteria for volume increase>
◎: More than 16 out of 20 responded that they could increase their volume softly ○: 11-15 out of 20 responded that they could increase their volume softly △: 6-10 out of 20 respondents However, it was answered that the volume could be raised softly ×: 5 or less of 20 people answered that the volume could be raised softly

(Test Example 5: Evaluation of washing off)
After the evaluation of Test Example 4 by the panel 20 people, a commercially available shampoo was used to carry out a normal hair washing treatment, and the sensory evaluation was performed on washing off from the hair according to the following evaluation criteria.

  In addition, about washing off, it evaluated about the frequency | count of hair washing until it does not feel the residual feeling of powder. As a commercially available shampoo, Gatsby Perfect Clear Shampoo (trade name, manufactured by Mandom) was used.

<Evaluation criteria for wash-off>
◎: More than 16 of 20 people answered that shampoo was sufficiently foamed and could be easily washed off at one time ○: More than 16 of 20 people were weak in foaming of shampoo, but could be washed off at once △: More than 16 out of 20 respondents said that it was necessary to wash the hair twice. ×: More than 16 out of 20 respondents said that it was necessary to wash the hair more than 3 times.

  From the results of Tables 1 to 3, it can be seen that the foam-like hair styling agent of each example is excellent in foam stability, and thus discharge in a foam form is sustained. Especially, it turns out that discharge in a foam form continues more stably by using together (C) component and (D) component. In addition, it can be seen that the hair after styling has an excellent texture without squeaky feeling, can increase the volume of the hair softly, and has an excellent effect in washing off at the time of shampooing.

  On the other hand, it turns out that the comparative examples 1-2 which do not contain (A) component or (B) component which is a structural component of this invention cannot fully show the effect of this invention. Moreover, in the comparative example 3 which replaced the (B) component of this invention with the other powder, it turns out that it is inferior to the volume-up effect not only in the discharge in a foam form not continuing. In Comparative Examples 4 to 7 that do not contain the component (C), which is a constituent of the present invention, not only the ejection in the foam form is not sustained, but also the squeaky feeling and texture are inferior, and further, the hair is not washed out. It turns out that it is a thing.
