Abstract

PURPOSE: To provide an oily make-up cosmetic composed of an oil component and a pigment hydrophilicized by coating with a DNA, having excellent durability of the cosmetic effect and moistness and useful for rouge, foundation, etc. CONSTITUTION: This cosmetic contains (A) a pigment coated with a DNA (preferably a DNA having a rather poor solubility in water and an average molecular weight of 500,000-5,000,000) or its water-soluble salt and (B) an oil component (e.g. paraffin, lanolin or squalane). The amount of the component B is generally 60-90wt.% and the DNA is usually extracted from the testis of salmon or herring. The compound A is preferably produced by dissolving or dispersing DNA or its water-soluble salt in purified water, supplying a pigment into the solution or dispersion, uniformly dispersing the pigment by mechanical means and drying and crushing the dispersed product.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oily makeup cosmetic composition which is excellent in the durability of the cosmetic effect and the moisturizing effect.

[0002]

2. Description of the Related Art Since an oily makeup cosmetic is basically a two-component system consisting of an oil component and a pigment, an oil-based makeup cosmetic can be used in order to enhance the durability of its cosmetic effect and moisturizing effect. At present, it depends on the selection of the ingredients. However, no matter how effectively oil components with high adhesiveness such as petrolatum and high molecular weight esters are mixed, the cosmetic effect during application is maintained for 2-3 hours on the skin that repeatedly stretches from beginning to end. However, with the disappearance of the cosmetic effect, the moisturizing effect also changes to a dry feeling. In order to prevent this, some kind of ingenuity must be added to the pigment without depending only on the oil component. Although hydrophilic surface-treated pigments are considered solely for the purpose of improving adhesiveness and maintaining a moisturizing effect, surface-coated pigments conventionally developed for makeup cosmetics include silicone treatment, metal soap treatment, and resin. As seen in polymer treatment and the like, most of the treatment purposes are to modify the surface of the pigment to be treated from hydrophilicity to water repellency, and are not suitable for the purpose of this subject.

In view of such a situation, the present inventor has conducted diligent research to improve the difficulties of the prior art, and as a result, D
An oil-based makeup cosmetic comprising a hydrophilic pigment coated with NA or a water-soluble salt thereof and a specific oil component, and an oil-based makeup makeup excellent in the durability of the cosmetic effect and the moisturizing effect. The present invention has been completed and the present invention has been completed.

That is, the object of the present invention is to provide an oily makeup cosmetic composition which is excellent in the durability of the cosmetic effect and the moisturizing effect.

[0005]

In order to achieve the above object, the oily makeup cosmetic of the present invention has the following constitution. That is, the present invention is an oily makeup cosmetic which comprises a pigment coated with DNA or a water-soluble salt thereof and an oil component.

The DNA used in the present invention is deoxyribonucleic acid mainly extracted from salmon or herring testes, and its water-soluble salts include sodium salt, potassium salt and the like, all of which are known substances. .

The DNA-coated pigment of the present invention, or D
The coating pigment of the water-soluble salt of NA is obtained by dissolving and dispersing DNA or a water-soluble salt of DNA in purified water, adding the pigment, mechanically dispersing it uniformly, and drying and pulverizing.

The DNA used in the present invention is preferably slightly soluble in water, and the average molecular weight is 5 in that range.
It is preferably from 0,000 to less than 5 million.

The upper limit of the coating amount of the DNA or the water-soluble salt of DNA used in the present invention is not particularly limited, but is preferably 0.2 to 0.2 if it is an expensive component and the cost is taken into consideration. 20. It is O% by weight.

The amount of the coating pigment of the present invention of DNA or the water-soluble salt of DNA to be added to the oily makeup cosmetic is not particularly limited.

The type of pigment coated with the DNA or the water-soluble salt of DNA of the present invention is not particularly limited as long as it is not water-soluble, and all organic pigments and inorganic pigments can be coated. is there. Red 2 for organic pigments

Inorganic pigments include, for example, red iron oxide, yellow iron oxide, black iron oxide, sunflower, konjac, chromium hydroxide, manganese violet, cobalt hydroxide, cobalt titanate, titanium oxide, titanium mica, barium sulfate, mica, talc, kaolin. , Sericite and the like.

The oil component of the present invention is generally used in cosmetics and is not particularly limited as long as the stability and safety of the product are not impaired. Hydrocarbon waxes such as paraffin, ceresin, microcrystalline wax, natural product extraction waxes such as candelilla wax, carnauba wax, lanolin and its derivatives, castor oil, jojoba oil, natural extracted oils such as olive oil, monoester oil, diester oil, There are synthetic oils such as triglycerin, liquid hydrocarbon oils such as liquid paraffin and squalane, and silicone oils such as methyl silicone, methylphenyl silicone and cyclic silicone. Further, the compounding amount of the oily raw material used in the oily makeup cosmetic of the present invention varies depending on the kind to be used, but generally, the suitable compounding amount range is 60 to 90% by weight.

The oily make-up cosmetic composition of the present invention may contain an antioxidant, an antiseptic agent, a perfume and the like within a range not impairing the object of the present invention.

The oily makeup cosmetics of the present invention include lipsticks, foundations, eye shadows and the like.
