JP7063816B2 - Hair styling composition - Google Patents

Description

The present invention relates to a hair styling composition. More specifically, the present invention relates to a hair styling composition that can lightly and softly finish a hairstyle, is not sticky, and does not cause squeak or stiffness in the hair.

In the past, in hair styling products such as hair wax, it was common to add solid oil such as wax for the purpose of setting (hair styling) and fixing hair, but if the amount of oil is increased in order to increase the fixing force, Although the setting power (hair styling power) is improved, there is a problem that oiliness and stickiness due to the oil content are generated, the smoothness is reduced in the feeling of use, and the spreadability is deteriorated.

In order to solve the above problems, hair styling products containing powder components such as silica (silicic anhydride) have been proposed. For example, Patent Document 1 contains (a) a specific anionic surfactant, (b) a higher alcohol, (d) water, and (e) a liquid oil, and further contains (c) as a component (c-1). Disclosed is an oil-in-water emulsified hair styling product containing one or more selected from wax having a melting point of 55 ° C. or higher, (c-2) a specific hair styling resin, and (c-3) anhydrous silicic acid. In particular, (c-3) anhydrous silicic acid is said to be effective in producing parts such as lightness and fluffy feeling.

Patent Document 2 describes at least one selected from (A) anhydrous silicic acid and / or hydrophobic anhydrous silicic acid, (B) waxes, hydrocarbons, fatty acid ester oils and silicone oils, (C) surfactants. And (D) an emulsified composition for a hairdressing agent containing water and adjusting the content ratio of (A) and (B) within a predetermined range is disclosed, and (A) anhydrous silicic acid and / or hydrophobicization is disclosed. Due to the hair conditioning effect of silicon dioxide, it is possible to condition hair without stickiness, without the unnatural glare peculiar to oil agents, to obtain a light finish with a natural texture, and it is said to be excellent in re-adjusting properties.

However, although a hair styling product that utilizes the hair styling effect of anhydrous silicic acid can obtain a soft and light finish, it is caused by powder by adding an amount of anhydrous silicic acid (powdered hair styling agent) that exhibits the hair styling effect. It could be squeaky and give a stiff feel.

On the other hand, Na-acrylic acid graft starch is known as a superabsorbent polymer material, and Patent Document 3 discloses various cosmetics containing Na-graft starch acrylate. However, the hair conditioning effect of Na-acrylic acid graft starch was not known at all.

Japanese Patent No. 5761838 Japanese Unexamined Patent Publication No. 2012-102057 Japanese Unexamined Patent Publication No. 2011-256154

Therefore, an object of the present invention is to provide a hair styling composition capable of obtaining a soft and light finish, having no squeaky or stiff hair, and having a natural texture without stickiness.

As a result of diligent studies to solve the above problems, the present inventor has made stickiness by adding a predetermined amount of Na-graft starch acrylate, which has been conventionally used as an aqueous (highly water-absorbent) thickener. We have found that it is possible to arrange hair with a soft and light finish, and that there is no squeaky feeling or stiffness due to the powder formulation, and we have completed the present invention.

That is, the present invention
(A) Na acrylate-grafted starch of 0.01% by mass or more and less than 1.5% by mass,
(B) A surfactant consisting of at least one selected from an anionic surfactant and a nonionic surfactant, and
(C) Contains oil and
Provided is an oil-in-water emulsified hair styling composition, characterized in that the amount of the powdered hair styling agent is less than 1% by mass.

The hair styling composition of the present invention gives a soft and light finish (airy feeling) even when the amount of silicic acid anhydride (powdered hair styling agent) is small or not, and the hair is squeaky. It is possible to style hair with a natural texture that is not stiff and sticky.

The hair conditioner composition according to the present invention (hereinafter, also simply referred to as “hair conditioner”) is at least selected from (A) Na-grafted starch acrylate, (B) anionic surfactant and nonionic surfactant. It is an oil-in-water emulsified composition containing (C) an oil component as an essential component and a surfactant composed of one kind.

(A) Na Acrylic Acid Graft Starch The Na Acrylic acid graft starch (component A) in the hairdressing agent of the present invention is a sodium salt obtained by graft-polymerizing acrylic acid on starch, and is known as a highly water-absorbent polymer. Na-acrylic acid graft starch has conventionally been used as an adsorbent, a binder, an emulsion stabilizer, a hydrophilic thickener and the like in the cosmetic field.

Hair wax was prepared according to the formulations listed in Tables 1 to 5 below. The hair wax (sample) of each example was used by a specialized panel, and the following items (1) to (3) were evaluated according to the following criteria.

(1) Squeaking during application
Evaluation criteria:
A: No catch B: I feel a little caught C: I feel very caught

(2) Airy feeling after hair shaping A: Extremely fluffy finish B: Soft finish C: No fluffy finish

(3) Stickiness after hair shaping A: Not sticky at all B: Slightly sticky C: Sticky

It showed a good hair styling effect (fluffy (airy) hair styling) regardless of the condition, and did not feel sticky. In particular, in Examples 1, 2, 5 and 6 in which the blending amount of silicic anhydride was suppressed to 0.2% by mass or less, the hair could be conditioned airy without getting caught in the hair, and no stickiness was felt. In Examples 3 and 4 in which the blending amount of silicic anhydride exceeded 0.2% by mass, a slight feeling of catching occurred, but it was acceptable as a product. However, in Comparative Examples 1 and 2 in which 1% by mass or more of silicic anhydride was blended, the catching at the time of application was remarkably felt.

On the other hand, in Comparative Example 3 containing silicic acid anhydride but not Na-grafted starch acrylate, not only the hair was caught, but also a sticky feeling was generated. Further, in Comparative Example 4 containing neither silicic acid anhydride nor Na-grafted starch acrylate, a fluffy finish (airy feeling after hair shaping) could not be obtained.

In Comparative Examples 5 and 6 in which the blending amount of Na-acrylic acid graft starch was 1.5% by mass, even if the blending amount of anhydrous silicic acid was suppressed to 0.2% by mass, it was caught during application and sticky after hair shaping. Has occurred. In particular, in Comparative Example 6 in which the blending amount of the liquid oil was less than 4% by mass, the stickiness at the time of application and the stickiness after the hair styling were remarkably felt, and the airy feeling was also impaired.

From the results shown in Table 3, (B) Examples 1 and Examples 7 to 11 in which an anionic and / or nonionic surfactant was used as the surfactant were evaluated to be excellent in all items. Was done. However, in Comparative Example 7 in which only the amphoteric surfactant was used as the (B) surfactant, the emulsification could not be performed stably and a precipitate was observed, so that the characteristic evaluation was not carried out.

As shown in Table 4, in the present invention, it was confirmed that the same effect can be obtained even if the types of the solid oil content and the liquid oil content are changed.

In Table 5, the characteristics of the sample further blended with the resin (G component) were evaluated. In addition to the above items, "hair conditioning", "appearance" and "viscosity" were also evaluated according to the following criteria.

Evaluation items and evaluation criteria ・ Hair conditioning ability:
A ⁺ : Extremely excellent A: Excellent B: Normal C: Inferior

·exterior:
+: Good (uniform with no observation of precipitates)
-: Defective (precipitate is observed)

・ Viscosity:
+: Good (maintains the thickening effect of Na-grafted starch acrylate)
-: Defective (viscosity decrease (thickness reduction) occurred)

From the results shown in Table 5, when the resin is blended, the basic performances of no catching during application, airy feeling after hair shaping, and no stickiness after hair shaping are exhibited without any problem, and the hair shaping power is further improved. The tendency to do was confirmed. However, in terms of appearance and thickening effect, Example 20 containing a nonionic resin ((VP / methacrylamide / vinylimidazole) copolymer and (vinylpyrrolidone / VA) copolymer) or a cationic resin (polyquaternium-11) is blended. No problem occurred in No. 22 to 22, but in Examples 23 to 27 in which an amphoteric or anionic resin was blended, precipitation or inhibition of the thickening effect by Na-acrylic acid graft starch was observed.
