JP5414659B2 - Mist cosmetic for hairdressing - Google Patents

Description

  The present invention relates to a mist cosmetic for hairdressing agents. More specifically, the present invention relates to a mist cosmetic for hairdressing agent characterized by discharging a gel-like composition in the form of a mist.

  As a cosmetic that can be uniformly applied over a wide range of hair, prevents dripping from the hair after application, and further enhances the feeling of use, a gel-like composition has been conventionally used as a pump container, etc. There are mist cosmetics that are filled in a cosmetic spray container and discharged in a mist form (see, for example, Patent Documents 1 to 3).

  However, although these forms of mist cosmetics can enhance the feeling of use, when a set agent such as a commonly used film-forming polymer is blended to impart sufficient hair-styling power, a film is formed on the hair. Due to the characteristics of haircutting, there is a problem that once hair is set, it cannot be restyled. There is also a problem such as clogging of the discharge port due to long-term use.

  Therefore, attempts have been made to impart a hair-styling effect using a specific oil component. For example, gel-like hair that contains low-crystalline cellulose, polyoxyalkylene adducts such as waxes, and water, has a specific viscosity or higher, and is sprayed into a fine mist when used. Cosmetics have been proposed (see, for example, Patent Document 4).

  However, even with these attempts, sufficient hair styling power has not been imparted compared to normal hair styling agents, and the stickiness of oily components such as waxes occurs, resulting in a problem that the feeling of use deteriorates. is there.

  EXAMPLES Hereinafter, although this invention is demonstrated further in detail based on an Example, this invention is not limited only to these Examples. The blending amount represents “% by mass” unless otherwise specified.

(Sample preparation 1)
According to the composition described in Table 1 and Table 2, each gel-like composition of Examples 1-6 and Comparative Examples 1-6 was prepared, and it used for the following evaluation. The results are shown in Tables 1 and 2. In addition, all evaluation was implemented on the constant conditions of constant temperature and humidity of 23 degreeC and 60% of humidity.

(Test Example 1: Evaluation of storage stability)
The prepared gel-like compositions of each Example and each Comparative Example are filled in a 60 mL transparent glass container, and are stored in a reciprocating thermostat (a thermostat that varies (cycles) within a range of 5 to 40 ° C.) for one month. Stored for a while. The “storage stability” after one month was visually evaluated according to the following evaluation criteria.

<Evaluation criteria for storage stability>
○: No change observed immediately after production Δ: Slight change such as separation is observed ×: Clear separation is observed

(Test Example 2: Evaluation of discharge mode)
The prepared gel-like compositions of each Example and each Comparative Example were filled into a 50 mL container equipped with a pump-type dispenser (Y-150, manufactured by Yoshino Kogyo Co., Ltd., discharge amount 0.15 mL / 1 push). It was stored in a constant temperature bath at 0 ° C., and the following operation was repeated every day to conduct a discharge (spray) form confirmation test.

  A sample was taken out from the thermostat and immediately discharged (sprayed) 10 times. After discharge (spraying), each sample was returned to the thermostat and the same test was carried out three times daily, morning, noon and evening. This operation was repeated until the content of the gel-like composition disappeared completely or until it was not discharged (sprayed) due to clogging or the like, and the state was evaluated according to the following criteria.

<Evaluation criteria for discharge mode>
○: No abnormality is observed in the discharge (spray) state within the observation period, and the mist form is maintained. Δ: The discharge (spray) state is slightly weakened during the observation period, but the mist form is maintained. X: Cannot be applied, or cannot be discharged (sprayed) in a mist form, or cannot be discharged at all within the observation period

(Test Example 3: Evaluation of applicability)
The prepared gel composition of each example and each comparative example was filled in a container equipped with a pump-type dispenser (Y-150, manufactured by Yoshino Kogyo Co., Ltd., discharge amount 0.15 mL / 1 push). Subsequently, 20 persons with a sensory evaluation panel used a wig (Lesson Mannequin: manufactured by Eucalyptus Japan Co., Ltd.) for spray application to the hair, and “applicability” was subjected to sensory evaluation according to the following evaluation criteria.

<Evaluation criteria for applicability>
○: 16 or more of 20 people answered that it can be uniformly applied over a wide range without dripping. Δ: 10-15 people out of 20 answered that it can be uniformly applied over a wide range without dripping. × : Nine out of 20 people answered that they can be applied uniformly over a wide area without dripping

(Test Example 4: Evaluation during hair styling)
After the evaluation in Test Example 3, the 20 panelists gave hair to the hair as if they were rubbed together, and sensory evaluation was performed according to the following evaluation criteria for “stickiness” and “hairstyling power” during hairdressing.

  The evaluation of “hair-styling ability” was performed by setting up the hair so that the hair was rubbed together, and maintaining the raised shape as having high hair-styling ability.

<Evaluation criteria for stickiness>
○: 16 or more out of 20 responded that there was no stickiness △: 10-15 out of 20 responded that there was no stickiness ×: 9 or less out of 20 responded that there was no stickiness

<Evaluation criteria for hair styling power>
○: 16 or more out of 20 responded that hair styling ability is high △: 10 to 15 out of 20 responded that hair styling ability was high ×: 9 or less of 20 persons answered that hair styling ability was high

(Test Example 5: Evaluation during re-styling)
One hour after the evaluation in Test Example 4, the 20 panelists gave hair to the hair again, and subjected to sensory evaluation according to the following evaluation criteria.

<Evaluation criteria for re-hairdressing>
○: More than 16 out of 20 responded that they can restyle their hair as desired △: 10 to 15 out of 20 responded that they could restyle their hair as intended ×: 9 or fewer out of 20 , You can restyle your hair as you want

  From the results shown in Tables 1 and 2, the gel-like composition used in the mist cosmetic for hairdressing agents of the present invention described in each example has an effect of excellent storage stability. It can be seen that the powder can be blended stably in the product. It can also be seen that in the form of the mist cosmetic for hairdressing agent, there is no clogging of the discharge port even after long-term use, and the mist-like discharge form is maintained. Furthermore, since it can be applied uniformly over a wide range without dripping, and the hair can be styled without a sticky feeling, it can fully exert its excellent hair-styling power and has an excellent effect on re-styling. I understand that.

  On the other hand, in Comparative Examples 1 and 2 in which the component (A) of the present invention is replaced with other powders, it is understood that the hair styling characteristic peculiar to the present invention is not obtained at all. Further, in Comparative Examples 3 to 5 replaced with a thickener that is widely used to form a normal gel composition, since it cannot be ejected in a mist form, it cannot be applied uniformly and has excellent hair styling power. It can be seen that re-hairing properties cannot be obtained. Furthermore, the comparative example 6 which does not mix | blend ethanol was inferior to storage stability.
