Description

The present invention relates to a non-aqueous hair cosmetic composition containing an ultraviolet absorber and excellent in low-temperature stability, and a hair treatment method using the non-aqueous hair cosmetic composition.

Conventionally, in order to avoid the adverse effects of UV rays, UV absorbers have been incorporated into cosmetics for skin such as sunscreen cream, but recently it has become possible to prevent damage to hair by UV rays. Therefore, hair cosmetics containing an ultraviolet absorber have been developed.

As such a hair cosmetic, for example, an aerosol spray type that is sprayed onto the hair and onto which various components including an ultraviolet absorber are attached has been proposed (Patent Document 1). With such a type of hair cosmetic composition, for example, the ultraviolet absorber can be effectively attached to the hair after the hair styling without breaking the hairstyle.

JP, 2015-113281, A (claim etc.)

On the other hand, hair cosmetics containing an ultraviolet absorber tend to become cloudy when placed in a low temperature such as the temperature in winter in cold regions. Unlike aerosol sprays, leave-on type hair cosmetics may be commercialized by putting them in a transparent container whose contents are visible, but they are exposed to low temperatures during distribution and storage in warehouses. If it becomes cloudy, the commercial value may decrease.

The present invention has been made in view of the above circumstances, and an object thereof is a non-aqueous hair cosmetic composition containing an ultraviolet absorber and excellent in low temperature stability, and hair using the non-aqueous hair cosmetic composition. And providing a processing method.

The non-aqueous hair cosmetic composition of the present invention capable of achieving the above object contains the following components (A) to (C), and is applied to wet hair and then dried without rinsing. It is characterized by being used.
(A) UV absorber (B) Alkyl benzoate or 2-ethylhexyl isononanoate (C) Volatile cyclic silicone

The hair treatment method of the present invention is characterized by using the non-aqueous hair cosmetic composition of the present invention.

ADVANTAGE OF THE INVENTION According to this invention, the ultraviolet absorber is mix|blended and the non-aqueous-type hair cosmetics excellent in low temperature stability and the hair treatment method using the said non-aqueous-type hair cosmetics can be provided.

The non-aqueous hair cosmetic composition of the present embodiment contains (A) an ultraviolet absorber, (B) an alkyl benzoate or 2-ethylhexyl isononanoate, and (C) a volatile cyclic silicone. The (A) ultraviolet absorber is a component for preventing damage to the hair due to ultraviolet rays, and the (C) volatile cyclic silicone is a component that serves as a medium (solvent) for non-aqueous hair cosmetics. Has low compatibility.

The non-aqueous hair cosmetic composition according to the present embodiment uses (B) alkyl benzoate or 2-ethylhexyl isononanoate to enhance the solubility of the (A) component in the (C) component to give a transparent appearance. It is also possible to secure low temperature stability such that the transparent appearance can be maintained even at low temperature.

Further, when the hair cosmetic containing the component (A) is applied to wet hair and dried, the hair becomes a bundle during the drying process, and the state of the bundle is maintained even after drying. The finger-passing property of the hair (after drying) deteriorates. However, by blending the component (B) together with the component (A) and the component (C), it is possible to prevent the hair from becoming a bundle. Therefore, when the non-aqueous hair cosmetic composition of the present embodiment is used, dry The subsequent finger passage of the hair is also good.

Comparative Examples 1b-1g
A non-aqueous hair cosmetic composition was prepared in the same manner as in Example 1 except that the ester oil shown in Table 1 was blended in place of the alkyl benzoate ( _C12-15 ) as the component (B).

The following evaluations were performed on the non-aqueous hair cosmetics of Examples 1a and 1b and Comparative Examples 1a to 1g.

<Finger-passing properties after drying>
Prepare a plurality of hair bundles that have been hair-dyed and have damaged tips, and after washing with water, apply an appropriate amount of the non-aqueous hair cosmetic composition of any of the Examples and Comparative Examples while the hair is wet. And dried using a dryer. When a finger was put through each of the dried hair bundles, the finger-grip with slipperiness was evaluated as "the finger-grip property after drying".

The evaluation of the finger-passing property after drying was carried out by each of three evaluators based on the case of using the non-aqueous hair cosmetic composition of Comparative Example 1a, and the classification was performed according to the following evaluation criteria.

<Low temperature stability>
Each of the non-aqueous hair cosmetics of Examples and Comparative Examples was filled in a transparent glass bottle and sealed, and then allowed to stand in a cool dark place of -10°C for 1 month and then stored in an environment of -10°C. Then, the transparency of each non-aqueous hair cosmetic composition was visually evaluated, and when it was transparent, it was marked with “◯”, and when it was cloudy, it was marked with “x”.

The results of the above evaluations are also shown in Table 1.

In Table 1, “(B′)” means a component used in place of the component (B). In addition, in Table 1, "linear dimethyl polysiloxane (1)" has a kinematic viscosity at 25° C. of 1.4 mm ² /s [corresponding to component (D)] "Dimethylpolysiloxane (2)" means those having a kinematic viscosity at 25° C. of 20 mm ² /s [not corresponding to the component (D)] (also in Tables 3 and 4 below).

On the other hand, among the non-aqueous hair cosmetics of Comparative Examples 1b to 1g in which other ester oil is blended instead of the component (B), the non-aqueous hair cosmetics of Comparative Examples 1b and 1c in which the ester oil is a monoester are The non-aqueous hair cosmetics of Comparative Examples 1d to 1g, in which the ester oil was a diester, remained transparent even after being stored at -10°C for 1 month and had good low-temperature stability. It became cloudy when stored in, and was inferior in low temperature stability. When the non-aqueous hair treatment agents of Comparative Examples 1d to 1g are stored at -10°C for 1 month and then returned to room temperature, a yellow precipitate which is presumed to be an ultraviolet absorber is produced and the agent is separated. There were things.

Then, the non-aqueous hair cosmetics of Comparative Examples 1b to 1g have a finger-passing property of the hair after drying which is equivalent to the case where the non-aqueous hair cosmetic of Comparative Example 1a, which is the reference, is used. It was inferior to the case of using 1b of the non-aqueous hair cosmetic composition.
