Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to e-cosmetics containing a specific powdery composition.

[Technical background of the invention and its problems]

Conventionally, hydrocarbons such as squalane, squalene, liquid paraffin, liquid polybutene, and liquid lanolin; high-grade Jllf fatty acid esters such as 2-osyl myristate (trade name: Egiseval HO), etc. have been used as base ingredients for cosmetics. There is. These are suitable as base ingredients for cosmetics due to their affinity for the skin and good permeability.
They are oily liquids at room temperature, and have limited miscibility with the base components normally used in creamy or solid cosmetics, as well as poor compatibility with water, so there are limits to their use. . For this reason, attempts have been made to powderize oily substances such as squalane by using proteins such as casein and sodium caseinate as coating agents, but the resulting powdered compositions have poor bacterial resistance and are prone to mold. and easily corrupted.

[Purpose of the invention]

An object of the present invention is to solve the problems of oily bases conventionally used in cosmetics and to provide a cosmetic containing an improved powder composition containing an oily base.

[Structure of the invention]

The present invention consists of one or more compounds selected from the group consisting of squalane, squalene/% liquid paraffin, liquid polybutene, liquid lanolin, 2-octyldodecyl 4listate, isotridecyl myristate, and hexadecyl 2-ethylhexanoate. The main components are a base component and a coating component that covers the base component and is made of one or more compounds selected from the group consisting of gum arabic, carrageenan, sodium alginate, and carboxymethyl cellulose, and the former and the latter. and a powder composition containing the following in a weight ratio of 5:95 to 98:20.

[Detailed description of the invention]

The powder composition used in the present invention comprises the group consisting of squalane, squalene, liquid paraffin, liquid polybutene, liquid lanolin, 2-octyldo-3-decyl state, isotridecyl myristate, and hexadecyl 2-ethylhexanoate. Compounds selected from (
One or more compounds selected from the group consisting of gum arabic, carrageenan, sodium alginate, and carboxymethyl cellulose (hereinafter referred to as a coating component) or Contains two or more types as main components.

The ratio of the base component to the coating component is 5:95 to 9 by weight.
You can choose from a range of 8 to 2 as appropriate.

If the amount of the coating component is less than 2% of the total amount of the coating component and base component, a powder composition cannot be formed. The strength of the coating covering the surface of the powder composition improves as the amount of coating components increases. If the strength of the coating is too low, the coating will be destroyed by a weak impact, the base component will ooze out, the powdered composition will become sticky, and the advantage of being powdered will be lost, which is not preferable. In addition, if the blending amount of the coating component exceeds 95% of the total amount of the coating component and base component, the strength of the coating will be too high, and the coating will not be destroyed and the Since the base component does not ooze out at all, it cannot be said that the base component exerts its protective effect on the skin. When gum arabic is used as a coating component, the amount thereof is preferably within a range that accounts for about 10 to 80 of the total weight of the coating component and base component, and carrageenan, sodium alginate, and carboxymethylcellulose are also used. When used, their blending amount is about 5 to 5 of the above total amount.
It is preferably within the range of 0 deuterium value. When preparing a powdered composition by the method described below, if the coating components such as 2-ginan, sodium alginate, or carboxymethyl cellulose are dissolved in water, the viscosity of the aqueous solution increases, making it difficult to homogeneously emulsify. Therefore, it is preferable to use a small amount of coating components and a binder such as microcrystalline cellulose. Also, in the case of t.

To facilitate homogeneous emulsification, the viscosity can also be lowered by increasing the amount of water used.

The stone powder composition used in the present invention can be prepared, for example, by the following method. First, an appropriate amount of a surfactant such as fatty acid ester of glycerin or glycol such as monoglyceride of stearic acid, propylene glycol monostearate, etc. is added to one or more of the base components, and while stirring, about The temperature is raised to 65 to 75°C to completely dissolve the surfactant to form an oil phase. On the other hand, add one or more of the coating components to an appropriate amount of water, add a binder if necessary, and then raise the temperature to about 65 to 75 degrees Celsius while stirring to completely dissolve the water. phase. Next, the oil phase is added little by little to the aqueous phase while stirring, and after the addition is complete, stirring is continued for about 30 minutes, followed by preliminary emulsification. The emulsion is homogenized under a pressure of about 150 to 200 pupils/d using, for example, a homogenizer, and the resulting emulsion is spray-dried using, for example, a hot-air spray dryer to form a powder. A composition.

When the powdered composition thus obtained is used as a cosmetic, its coating is destroyed, and the oily base component oozes out from the inside of the coating, thereby imparting a fatliquoring effect to the cosmetic. Furthermore, this powdered composition is not easily contaminated because it is covered with a film that is relatively resistant to contamination by microorganisms.

The cosmetic of the present invention contains the above-mentioned powder composition.

When the powder composition is incorporated into cosmetics, it may be incorporated in an effective amount into a base component system containing water and/or oily substances. Generally, it is appropriate to incorporate the powdered composition into cosmetics so that it has a weight value of about 0.01 to 70, preferably about 1 to 50. Examples of the above-mentioned oily substances include oils and fats, waxes, hydrocarbons, higher fatty acids, higher aliphatic alcohols, and their esters, which are known to be commonly incorporated into cosmetics. Available for use. In addition to the above, the cosmetics of the present invention can also contain anything that can be normally incorporated into cosmetics, such as humectants, thickeners, preservatives, emulsifiers, medicinal ingredients, fragrances, and emulsifiers. There are stabilizers.

71 Cosmetics of the present invention include white powder (face powder),
Powder products such as talcum powder and baby powder; Oil-based makeup products such as lipstick and eye shadow stick; Powder products that are mixed with water such as facial cleansing powder and whitening powder; Facial cleansing such as facial cleansing cream, cream, cream paste shampoo, etc. Or hair washing products; emulsified products such as nutritional creams and milk lotions, etc., but to take advantage of the characteristics of powder compositions, powder products, oil-based makeup products, and powder products that are mixed with water are recommended. etc. are preferable.
