Abstract

PROBLEM TO BE SOLVED: To obtain a lipstick composition which scarcely fades the color, has a good makeup-lasting property, does not give an uncomfortable touch such as a dry touch when used, and hardly changes with the passage of time, by including gluten or its component: glutenin or gliadin. SOLUTION: This lipstick composition contains gluten (a vegetable protein extracted from the seeds of a grain such as wheat or rye) or its component: glutenin or gliadin preferably in an amount of 0.1 to 50 wt.%. The lipstick composition is preferably a non-aqueous lip stick composition which does substantially not contain water and is obtained by adding the gluten or its component: glutenin or gliadin to essential components comprising 1 to 90 wt.% of a liquid oily raw material (for example, liquid paraffin, jojoba oil, castor oil, isopropyl myristate or dimethylpolysiloxane) and 0.1 to 50 wt.% of a coloring agent (for example, a legal pigment for lipsticks, titanium dioxide or nylon powder).

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lipstick composition which is resistant to discoloration, has good makeup lasting, has no uncomfortable feeling such as dryness in use, and has no color change with time.

[0002]

2. Description of the Related Art Lipstick is among many makeup cosmetics, and the role of its cosmetic effect is particularly important. In other words, it is not an exaggeration to say that a variety of effects can be achieved with a lipstick, such as a reddish, healthy expression, or a gorgeous, elegant expression, without other makeup cosmetics. One of the more recent makeup trends is
Lighter make-ups, such as just brushing eyebrows and applying lipstick, are becoming increasingly common among working and young women. In such a situation, the importance of lipstick has further increased, and busy modern women have been spared time to remake their makeup, and have come to have great interest and desire for discoloration and persistence of lipstick. . Under such circumstances,
Conventionally, various measures have been taken to improve the sustainability of lipstick. For example, a method of blending a large amount of a high-viscosity component or a coloring agent, but this method does not improve discoloration due to eating and drinking. Next, a method of compounding a coloring agent having a dyeing property is used, but in this method, no matter what color system the lipstick applied to the lip is, the colorant that is dyed and remains on the lip is a limited color system. Therefore, even if lipstick of any color is applied, the lip of the same color will be obtained over time after a lapse of time, and a color change at the time of lipstick application and after a lapse of time becomes a problem. There is also a method of blending a volatile component to increase the adhesion of the component remaining after volatilization, but it is not satisfactory, for example, in that the use feel is dry. As described above, various contrivances have been conventionally made, but they have not been satisfactory.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a lipstick composition which is hardly discolored, has good makeup lasting, has no uncomfortable feeling such as dryness in use, and has no color change with time. I have.

[0004]

Means for Solving the Problems The present inventors have conducted intensive studies in order to achieve the above technical object, and have found that gluten or one or two of its constituents, glutenin and gliadin, are obtained.
By blending more than one kind, it was found that the lipstick composition is hardly discolored, has good makeup durability, and has no discomfort such as dryness in use feeling and no color change over time. Was completed.

[0005] That is, the present invention relates to a method of preparing gluten or one or more of its constituents, glutenin and gliadin, from 0.1% by weight based on the total weight of the cosmetic.
It is characterized in that it is blended at 50% by weight. The preferred amount is 5% by weight to 30% by weight. This amount is 0.1
If the amount is less than 50% by weight, the desired lipstick does not have a sufficient makeup lasting effect.

Gluten as used in the present invention is a vegetable protein and is extracted from, for example, cereal seeds such as wheat and rye. Conventionally, it has been mainly used in foods as a raw material for fu and the like, and is commercially available as a raw material, so that it can be easily obtained on the market. It has very strong adhesive properties, and its constituent proteins are glutenin and gliadin.

The lipstick composition of the present invention comprises, in addition to a liquid oily raw material and a colorant as essential components, one or two of the above-mentioned gluten or its constituent components, glutenin and gliadin.
It is preferred that the composition is a non-aqueous lipstick composition containing at least one seed and substantially free of water.

[0008] It is not clear why the lipstick composition of the present invention is resistant to discoloration, has good makeup durability, and has no uncomfortable feeling such as dryness and no color change over time.
Gluten, glutenin, and gliadin come into contact with moisture and change to sticky elastic substances when they contain moisture. Since the lip always retains an appropriate amount of water, if this change occurs in the non-aqueous lipstick composition applied to the lip, it forms a sticky film and reduces the adhesion of the lipstick composition to the lip. It is presumed that it will increase. In addition, it is presumed that this film has elasticity and contains moisture, and does not have an uncomfortable feeling such as a dry feeling when used.

The liquid oily raw material referred to in the present invention may be any one generally used in cosmetics, and examples thereof include the following. Hydrocarbons such as liquid paraffin, liquid isoparaffin, and squalane; waxes such as jojoba oil; oils and fats such as castor oil and olive oil; esters such as isopropyl myristate; and silicones such as dimethylpolysiloxane. The amount of these liquid oily raw materials is usually 1 to 90% by weight, preferably 20 to 90% by weight.
70% by weight.

[0010] Examples of the coloring agent in the present invention include the following. In addition to legal pigments that are approved for use in lipstick, inorganic pigments such as titanium oxide and iron oxide; organic pigments such as nylon powder and crystalline cellulose; and composite pigments such as titanium mica. In addition, those obtained by subjecting these coloring agents to surface treatment with silicone, metal soap, higher fatty acid or the like can also be used. The compounding amount of these coloring agents is usually 0.1 to 50% by weight, preferably 5 to 20% by weight.

There are various types of lipsticks, such as a stick, a pouring (a metal dish or the like), and a liquid, and the lipstick composition of the present invention can be applied to any of them. In the lipstick composition of the present invention, in addition to the above-mentioned components, depending on the purpose such as a difference in shape such as a stick, a pouring, and a liquid, as long as the effects of the present invention are not impaired, including a solid oily raw material. Other than the above, oily raw materials, surfactants, antioxidants, medicinal ingredients, ultraviolet absorbers and the like can be blended.
