Abstract

The present invention relates to a makeup cosmetic composition characterized by containing microencapsulated water and hyaluronic acid liposomes.

Description

Makeup cosmetic composition containing moisture and hyaluronic acid microcapsules

Unlike normal skin, the lips are composed of two types of stratified squamous epithelium (epidermal keratin type and mucosal age), and internal harmful factors such as temperature, humidity, wind, and ultraviolet rays, diseases, age, habits Tolerance causes the physiological balance of the lips to collapse, resulting in roughness and dryness.

If it is caused by internal factors, it is very difficult without the combination of drugs, but if it is caused by external factors, it can be prevented by the lipstick base and can be masked by the color makeup.

In general, lipstick base is composed of oil and wax to form an oil film on the surface of the lips, which has a passive level of moisturizing function to protect the lips from moisture and external harmful factors such as cold and dry. There is a limit to the supply of moisture or moisturizer directly to the lips.

In skin care, a proper balance of water, moisturizer and oil is required from the viewpoint of moisture. Lip care has the same point of view, but unlike the skin, the skin has a small number of independent sebaceous glands, the sebaceous membrane is extremely thin. And since there is no NMF component and the rate of moisture evaporation is fast, the amount of moisture measured is small. In other words, the lips are less sensitive to the barrier (barrier) than the skin.

Table 1. Difference between Skin and Lips

The physiological balance of sensitive lips is broken and rough, and external factors include temperature, humidity, wind, and ultraviolet rays. Internal factors include illness, age, habits, and makeup behavior for women. The concept of skin care's moisture balance, that is, the proper balance of water, moisturizers and oils, also applies to lip care.

Of course, the individual difference is very large, but to keep your lips healthy

(1) We suppress volatilization of water from lips.

(2) It is necessary to supply water and NMF components.

With the conventional oil-based lipstick, the effect of (1) can be achieved, but the effect of (2) is difficult to achieve.

As a result of applying water and various ingredients to dry and rough lips, the amount of water when applying w / o cream containing water or a large amount of water is lower than that when applying oily or emulsifying lipstick. It cannot be interpreted as good. This can be guessed that the degree of roughening is progressed by applying a saliva to the rough lips, it can be seen that the role of the oil seal (oil seal) is very important for lips with less sebum.

The present inventors microencapsulate moisture and hyaluronic acid, which are known to be excellent moisturizing agents made by using biotechnology, to stably blend in lipstick bases, and actively supply moisture and moisturizers to the lips, thereby preventing the lips from being harmful to the outside. At the same time, it prevented the drying and roughening caused by the factor, and at the same time, it was surprising that the liposomeized moisturizer and the moisture were moist, that is, the moisturizing power lasted for a long time.

The present invention relates to a makeup cosmetic composition characterized by containing microencapsulated water and hyaluronic acid.

Hereinafter, the present invention will be described in detail.

In the cosmetic composition of the present invention, an oil-based lipstick containing moisture and a moisturizing hyaluronic acid and maintaining an oil-rich moist balance, water and a hyaluronic acid, which is a moisturizing agent, in order to overcome the stability problem of lipstick caused by directly mixing water, It can be stabilized by encapsulating and blending. However, when the water is directly formulated, the following problems may occur.

(1) Discoloration and crystallization of organic pigments occur due to contact with water.

(2) Agglomeration of the unpigmented pigment occurs by contact with water, and there is a decrease in saturation when remelt with age.

(3) When applied to the lips, whitening phenomenon peculiar to emulsified products occurs.

(4) Adding water does not necessarily affect the lips, but the lips may be rough.

(5) The glossiness of the appearance is significantly impaired by moisture volatilization from the lipstick surface.

In the makeup cosmetic composition of the present invention, the microencapsulated water and hyaluronic acid preferably contain 0.1 to 1.0 wt%. If the content of water and hyaluronic acid is less than 0.1% by weight can not be expected sufficient effect, if more than 1.0% by weight can not be expected to further increase the effect of overuse.

In the makeup cosmetic composition of the present invention, the base material may include a material commonly used in cosmetic compositions. Examples of such materials are microcrystalline wax, creesin wax, carnauba wax, candelilla wax, lanolin, esters and fatty alcohols, vegetable Oils, polymethyl methacrylate (PMMA), PVP / hexadecene copolymers, surfactants, organic and inorganic pigments and pearl pigments.

According to the conventional lipstick production method, the above raw materials are added, dissolved by heating to 80 to 90 ° C., and then cooled and molded using a mold to prepare a cosmetic composition.

In this process, when the microcapsules of water and hyaluronic acid are initially added to the liquid component and heated together for a long time, they are not precipitated and dispersed in the base. Therefore, after the heating and dissolving process of the make-up cosmetic base is finished, it is finally added and dispersed. And in compounding effects.

Hereinafter, although this invention is demonstrated concretely based on an Example, the technical scope of this invention is not limited to these Examples.
