Description

The present invention relates to aqueous compositions.

Conventionally, plastic powders such as nylon have been mainly used as feel improvers for external preparations for skin and makeup cosmetics. However, plastic powder has low biodegradability. For this reason, the impact of plastic powder on the environment becomes a problem, and it is necessary to refrain from using plastic powder.

As one of the highly biodegradable powders, there is an amino acid-based organic powder composed of amino acids and fatty acids. Amino acid-based organic powder is known to have a property of being excellent in water repellency because it is hardly soluble in water or an organic solvent.

Compositions containing amino acid-based organic powders are disclosed in, for example, Patent Documents 1 to 3. Patent Document 1 discloses a technique for improving usability and water repellency by blending an amino acid-based organic powder with a make-up cosmetic. Further, Patent Document 2 discloses a technique for blending an amino acid-based powder into a cream-like composition to give a cream-like appearance having a high-grade pearly luster and improving morphological stability. .. Further, Patent Document 3 discloses a technique for improving detergency, foam quality, etc. by blending an amino acid-based organic powder with a detergent composition containing a higher fatty acid.

Patent Documents 1 and 2 describe that an amino acid-based organic powder is blended in an oil-based composition, but do not describe that an amino acid-based organic powder is blended in an aqueous composition. Further, Patent Document 3 describes a cleaning composition containing a higher fatty acid salt and an amino acid-based organic powder. However, the technique described in Patent Document 3 merely disperses the amino acid-based organic powder due to the high viscosity of the cleaning agent composition, and is not a technique applicable to all aqueous compositions. Since the amino acid-based organic powder is excellent in water repellency, it is difficult to disperse the amino acid-based organic powder in the liquid layer of the aqueous composition. Therefore, it has been difficult to prepare an aqueous composition containing an amino acid-based organic powder.

An object of the present invention is to realize an aqueous composition capable of dispersing or redispersing an amino acid-based organic powder in the liquid layer of the aqueous composition.

As a result of diligent studies to solve the above problems, the present inventors have added (i) an amino acid-based organic powder, a specific surfactant, and a clay mineral, and (ii) the surfactant and the clay. A new finding that an aqueous composition in which the ratio of the content of amino acid-based organic powder to the content of mineral is within a specific range can be dispersed or re-dispersed in the liquid layer. The present invention has been completed. That is, the present invention includes the following configurations.

[1] Containing the following components A to D,
The content (A / B) of the component A with respect to the content of the component B is 300 or less.
An aqueous composition in which the content of component A (A / C) relative to the content of component C is 35 or less;
Component A: Amino acid-based organic powder Component B: At least one selected from the group consisting of alkyloxyhydroxypropyl arginine salts, nonionic surfactants having an HLB of 12.0 to 17.0, and cationic surfactants. Surfactant Component C: Smectite type clay mineral Component D: Water.

[2] The content of the component A is 0.01 to 20.0% by mass, the content of the component B is 0.005 to 2.0% by mass, and the content of the component C is 0.005 to 2.0% by mass. , 0.01-2.0% by mass, the aqueous composition of [1].

[3] The aqueous composition of [1] or [2] further comprising the following component E;
Ingredient E: Ethanol.

According to the aqueous composition of the present invention, the amino acid-based organic powder can be dispersed or redispersed in the liquid layer.

Hereinafter, examples of embodiments of the present invention will be described in detail, but the present invention is not limited thereto. The present invention is not limited to the configurations described below, and various modifications can be made within the scope of the claims. The technical scope of the present invention also includes embodiments or examples obtained by appropriately combining the technical means disclosed in the different embodiments or examples. Furthermore, new technical features can be formed by combining the technical means disclosed in each embodiment. In addition, all the academic documents and patent documents described in the present specification are incorporated as references in the present specification.

Unless otherwise specified in the present specification, "X to Y" representing a numerical range is intended to be "X or more and Y or less". Further, unless otherwise specified in the present specification, the mass% representing the content of the component is a value in which the mass of the entire aqueous composition is 100% by mass.

[1. Aqueous composition]
The aqueous composition according to the present invention contains the following components A to D and contains the following components A to D.
The content (A / B) of the component A with respect to the content of the component B is 300 or less.
An aqueous composition in which the content of component A (A / C) relative to the content of component C is 35 or less;
Component A: Amino acid-based organic powder Component B: At least one selected from the group consisting of alkyloxyhydroxypropyl arginine salts, nonionic surfactants having an HLB of 12.0 to 17.0, and cationic surfactants. Surfactant Component C: Smectite type clay mineral Component D: Water.

In the present invention, by having the above composition, it is possible to realize an aqueous composition capable of dispersing or redispersing the amino acid-based organic powder in the liquid layer. Here, "dispersing or redispersing the amino acid-based organic powder in the liquid layer" can be said to mean that the organic powder has wettability with respect to the liquid layer. The wettability state means a state in which the organic powder is present below the liquid surface of the liquid layer when the organic powder is stirred together with the liquid layer. On the other hand, the non-wetting state is a state in which the amino acid-based organic powder remains on the liquid surface (gas-liquid interface) of the liquid layer when the amino acid-based organic powder is stirred together with the aqueous composition. say.

Further, in the aqueous composition of the present invention, even in the two-layer form in which the organic powder exists as a wet powder layer in the liquid layer, the amino acid-based organic powder is dispersed in the liquid layer. I can say. The two-layer form includes, for example, (i) a form in which organic powder exists as a wet powder layer from below the liquid surface of the liquid layer near the liquid surface, and (ii) organic powder settles on the bottom of the liquid layer. However, a form in which the organic powder exists as a wet powder layer on the bottom thereof can be mentioned.

Further, in the present invention, the "aqueous composition" refers to a composition that does not substantially contain an oil agent. More specifically, the "aqueous composition" is a composition in which the oil agent is 3.0% by mass or less, preferably 1.0% by mass or less, and more preferably 0.5% by mass or less. Further, examples of the above-mentioned oil agent include fats and oils, waxes, silicone oils, hydrocarbons, ester oils and the like.

Further, the aqueous composition of the present invention is preferably a liquid composition having a viscosity at 25 ° C. of 1000 mPa · s or less, and more preferably 500 mPa · s or less. The viscosity can be measured by, for example, a B-type viscometer: VISCTER TV-25 (manufactured by Toki Sangyo Co., Ltd.) or a tuning fork type vibration viscometer: SV-10A (manufactured by Kitahama Seisakusho Co., Ltd.).

The viscosities of the cream and gel compositions exceed 1000 mPa · s. For such a composition, the organic powder can be dispersed and blended regardless of the wettability.

On the other hand, in order to disperse and blend the organic powder with respect to the liquid aqueous composition, it is necessary that the organic powder has wettability with respect to the liquid layer of the aqueous composition. Surprisingly, the present inventors have found a novel finding that the organic powder has wettability with respect to the liquid layer of the aqueous composition by blending the above components A to D.

Further, the aqueous composition of the present invention may further contain component E: ethanol in addition to the above components A to D. The aqueous composition of the present invention may contain other components in addition to the above-mentioned components.

The content (A / B) of the component A with respect to the content of the component B is 300 or less, preferably 2 to 250, and more preferably 5 to 200. Within the above range, the occurrence of stickiness due to an excess of smectite-type clay mineral (component C) can be suppressed. Further, considering the possibility of loss of the effect of the component A due to the insufficient amount of the component A, the A / B may exceed 0.

The content (A / C) of the component A with respect to the content of the component C is 35 or less, preferably 0.1 to 30, and more preferably 1 to 25. Within the above range, the occurrence of stickiness due to an excess of smectite-type clay mineral (component C) can be suppressed, and the possibility of excessive foaming can be suppressed. Further, considering the possibility of loss of the effect of the component A due to the insufficient amount of the component A, the A / C may exceed 0.
