Description

Solid foundation cosmetic composition without sweating {Cosmetic composition of solid foundation without sweating phenomenon}

The present invention relates to a solid foundation cosmetic composition having no sweating effect, and more particularly, to a solid foundation cosmetic composition having no feeling of sweating when oil is eluted to the surface even with a temperature change of the external environment.

In the conventional solid foundation, the oil in the contents elutes to the surface due to the temperature change of the external environment during a certain time after the molding, and the pigment in the contents elutes or the eluted oil flows out, resulting in poor appearance as well as many uses. It has some disadvantages that make it uncomfortable.

In order to solve this sweating, a method of increasing the content of the wax, or adding powder or low melting point wax having excellent oil absorption ability to the cosmetics has been proposed.

For example, U. S. Patent No. 5,176, 902 discloses a method of reducing sweating by applying a new wax system to a stick formulation containing a large amount of pigment to increase hardness. There is a disadvantage. In addition, U.S. Patent No. 4,695,452 discloses stick cosmetics provided with oiliness, soft and smooth application by mixing low melting point wax. However, the use of wax having a low melting point can improve the feeling of use, but the hardness decreases, resulting in sweating. This is not completely solved.

In addition, Japanese Patent Laid-Open No. Hei 2-172902 discloses a cosmetic composition in which porous silica powder having excellent oil absorption ability is mixed to improve usability such as spreadability and spreadability, and at the same time reduce sweating. However, when the powder having excellent oil absorption power is mixed, the apparent hardness increases as the content increases, but since the binding matrix between the wax and the powder is weakened, a fatal defect that occurs when the product is in contact with the container is broken. It is implicated.

Therefore, the technical problem to be achieved by the present invention is to solve the above problems to provide a solid foundation cosmetic composition with a very good feeling of use, such as adhesion, application, makeup persistence, water resistance, oily feeling as well as no sweating phenomenon in the temperature change. .

In order to achieve the above technical problem, the present invention provides a solid foundation cosmetic composition containing 1 to 15% by weight of sorbitan sulfate based on the total weight of the composition in the solid foundation cosmetic composition containing oil and wax.

The oil used in the solid foundation cosmetic composition according to the present invention may contain 1 to 30% by weight of a volatile silicone oil such as cyclomethicone to reduce oiliness.

Hereinafter, the present invention will be described in detail.

A feature of the solid foundation cosmetic composition according to the present invention is that it contains sorbitan oleate.

The sweating phenomenon in a system such as a dispersible cover makeup cosmetic composition composed of an oil-wax-pigment is mainly attributable to the change in the volume of the oil itself or the volume expansion between the oil-wax at the temperature change. That is, sweating is a phenomenon in which the oil component in the solid composition flows out from the inside of the solid by the volume expansion due to the temperature rise. To prevent such sweating, it is recommended to use a raw material having no difference in the volume expansion ratio between the oil and the wax. Preferably, the presently used raw materials are limited in reducing the difference in volume expansion ratio between oil and wax. Perspiration, such as emulsion-based solid foundation cosmetic compositions consisting of water-oil-pigments, is caused by the difference in volume expansion between oil and wax, as is the case with dispersible cover makeup.

However, sorbitan oleate used in the present invention prevents sweating by inhibiting the volume expansion rate due to the temperature change of the external environment by gelling oil, especially in pomade or ointment without water.

That is, the sorbitan oleate used in the present invention is composed of a lipophilic portion composed of fatty acids and olives and a hydrophilic portion having a polyalcoholic group, and thus has a surface-active ability, thereby replacing the use of an existing emulsifier. Because it has the ability to gel in any kind of oil, it promotes the gelation of the trauma in the solid foundation of oil-in-water type to prevent sweating by suppressing the rate of rise of the oil according to the temperature rise.

In addition, by using a large amount of volatile silicone oil that could not be used in the process of the three-mill mill of the emulsified solid foundation dispersed cover makeup, the greasy oiliness disappears and the burden on the makeup can be greatly reduced.

In the solid foundation cosmetic composition according to the present invention, the content of sorbitan sulfate is 1 to 15% by weight, preferably 2 to 6% by weight based on the total weight of the composition. If the content is less than 1% by weight, the antiperspirant effect may be insignificant, and if the content exceeds 15% by weight, the feeling of use may deteriorate.

Oils that can be used in the solid foundation cosmetic composition according to the present invention include ester-based oils, volatile / non-volatile silicone oils, etc., these oils may be used alone or mixed with each other. In particular, in order to reduce the oiliness of the cosmetic composition, it is preferable to use 1 to 30% by weight of a volatile silicone oil such as cyclomethicone.

In addition, in the present invention, in addition to the essential components described above, it is possible to use general ingredients used according to the purpose of use of cosmetics. For example, animal, vegetable, mineral or synthetic waxes for hardness formation, polar or nonpolar oils for controlling the feel, surfactants for fluidity and dispersion efficiency, pigments for controlling cosmetic effects and usability, and preservatives, UV absorbers , Polymers, fatty alcohols and fragrances can be blended as appropriate.

In addition, in order to impart cosmetic functionality, it can be manufactured by having a combination of a sunscreen stick and a whitening stick function. Therefore, a sunscreen or a whitening agent or the like may be added to the composition according to the present invention.

Hereinafter, the present invention will be described in detail with reference to Examples.
