Description

High Moisturizing Long Lasting Lipstick Composition

The present invention relates to a lipstick composition having both a durable function and a high moisturizing effect that are not easily buried. More specifically, a stable moisturizing ingredient (polyalcohol; e.g. glycerin) is stably formulated as a highly moisturizing complex stabilized with galactosyl ceramide, cholesterol, and the like on a persistent lipstick base containing volatile silicone oil as a periodic agent. The present invention relates to a lipstick composition that has excellent sustainability and at the same time has an excellent moisturizing effect that could not be expected from lipstick.

In general, lipstick is composed of an oil-based wax, oil and pigment, and has been limited to a softening effect on the lips and a function of expressing various colors. In addition, in the early 1990s, various durable products have been proposed and developed to solve the problem that the makeup is easily erased by being easily buried, which is the biggest disadvantage of the existing lipstick. However, such a persistent lipstick simply emphasizes the function of not applying after the lipstick is applied to the lips, so that after the makeup volatile oil volatilizes on the surface of the lips, the lips may dry out over time and inevitably cause a pulling phenomenon. In addition, the existing general lipstick simply formed a physical shielding film by the oily component consisting of oil and wax on the lip surface, and thus could not show a great moisturizing effect.

Hereinafter, a known technique for improving the persistence and moisturizing effect of lipstick is as follows.

European Patent Publication No. 94-602905 proposes a persistent cosmetic composition which uses a large amount of volatile solvent and silicone resin and also contains wax, oil, and pigment components, and has a low smearing effect, compared with ordinary lipstick. Although the persistence aspects such as squeezing were significantly improved, mainly after use of volatile solvent, silicone resin, wax and pigment, the makeup of the lipstick was accompanied by a drawback due to the lack of moisturizing properties due to lack of moisture retention. In Japanese Patent Application Laid-Open No. 94-287109, by using one kind such as dipropylene glycol and an oil-soluble monohydric alcohol, the dyeability of the lipstick containing tar pigments such as red 218, red 223, and orange 201 is improved. Proposes a composition for oily lips with enhanced color persistence, but uses the same oily base as ordinary lipstick As, after use lipstick, falls a lasting effect because of the lipstick significantly easier Loose clothes, cups, etc., it is difficult airway represents a special moisturizing lipstick hagieneun kinks in general will largely insufficient. In addition, as a method for improving the moisturizing properties of the lipstick, Japanese Patent Laid-Open No. 61-83110 discloses a wax and a dispersant such as phytosterol, cholesterol, phospholipid and cations, anions, nonionics and amphoteric surfactants. A composition for imparting a moisturizing effect to the lips by emulsifying water in an oil component has been proposed. US Patent No. 5,085,856 indicates that the present invention has a problem in storage stability, and stabilizes water using an appropriate type of emulsifier. Insisted on a lipstick composition. However, this lipstick composition containing water not only has a problem of long-term storage stability, but also during the molding of the lipstick, since water is actively volatilized, it is impossible to stably match water to the finally formed lipstick. International Publication No. 94-06401 attempted to stabilize a large amount of moisturizer to lipstick using a coupling agent of oil and a moisturizer such as glyceryl oleate / propylene glycol (1: 1) and glyceryl monostearate. Patent 94-06400 attempts to stabilize the moisturizer with surfactants and lecithins having kraft points below room temperature, such as sorbitan oleate and sorbitan sesquioleate.

However, inevitably, the surfactant and the coupling agent used at this time may cause some irritation to the skin of the lips having an extremely thin keratin structure, and the inventions for improving the moisturizing properties are similar to those of ordinary lipsticks. Since it persists, it is easy to bury in the same way as conventional lilvan lipsticks, and has a disadvantage of being erased.

Accordingly, an object of the present invention is a moisturizing agent (eg, glycerin, 1,3-butylene) that is extremely difficult to stabilize in a lipstick composition composed of volatile oil, wax, etc., which shows persistence, in order to solve the problems of general and persistent lipsticks. Glycol) is stabilized by forming a highly moisturizing complex using galactosyl ceramide and cholesterol having a structure similar to keratin components with moisture control function in the skin of the human body, without using any surfactant which may cause irritation. A large amount of moisturizer is stably formulated into a persistent lipstick base to significantly improve the persistence of ordinary lipsticks, and at the same time provide a highly moisturizing long lasting lipstick composition exhibiting an excellent moisturizing effect.

The lipstick composition according to the present invention contains from 0.1 to 60 parts by weight of volatile oil as a main component and from 0.1 to 70 parts by weight of a highly moisturizing complex consisting of galactosyl ceramide, cholesterol, polyhydric alcohol and liquid oil.

In particular, the highly moisturizing complex is 1 to 70 parts by weight of galactosyl ceramide, 0.1 to 50 parts by weight of cholesterol, 0.1 to 90 parts by weight of polyhydric alcohols (eg, glycerin, 1,3-butylene glycol, etc.), 0.1 to 50 parts of liquid oil. It is composed of parts by weight.

In the lipstick composition, in addition to the above components, a solidifying agent wax, a general non-volatile liquid oil, a pigment, stearalconium hectorite, and the like may be used as necessary.

Hereinafter, the present invention will be described in detail.

Galactosyl ceramides used in the highly moisturizing complexes having a moisturizing effect in the lipstick composition of the present invention are components having a similar structure to the keratin component having moisture control function of the human skin, and a hydrophilic moisturizer imparts the sustainability of the present invention. It shows a great effect on stabilization in volatile oil base, and when the lipstick of the present invention is applied to the lip surface, it forms a soft lipid film on the lip surface to improve color persistence and additional moisturizing effect. Preference is given to using from 1 to 70 parts by weight. If the blending amount is less than 1 part by weight, the polyhydric alcohol, which is a moisturizer, cannot be effectively stabilized in the lipstick, and when it is 70 parts by weight or more, the viscosity of the high moisturizing complex itself is too high, and excessive bubbles are produced during production. In addition, cholesterol shows an effect of increasing the solubility of galactosyl ceramide in the high moisturizing complex, but the effect is not sufficiently exhibited at 0.1 parts by weight or less, and the viscosity of the high moisturizing complex is not good at 50 parts by weight or more.

The polyhydric alcohol used as the main moisturizer in the present invention may be glycerin, 1.3-butylene glycol, sorbitol, propylene glycol, etc., the content of the polyhydric alcohol is 0.1 to 90 parts by weight, sufficient moisturizing at 0.1 parts by weight or less It is difficult to expect the effect, and when it exceeds 90 parts by weight, stabilization is difficult.

In addition, in the high moisturizing composite used in the present invention, a liquid oil is used at room temperature, but 0.1 to 50 parts by weight of hydrocarbon-based oils, ester oils and higher alcohols may be used, and the viscosity control function of the high moisturizing composite is less than 0.1 part by weight. There is little and it is difficult to stabilize a moisturizer more than 50 weight part.

The lipstick composition of the present invention can impart a moisturizing effect that was not expected in normal and sustained lipsticks by using 0.1 to 70 parts by weight of the high moisturizing complex composed of the above ingredients, and use the high moisturizing complex at 0.1 parts by weight or less. When moisturizing effect is not enough, when it exceeds 70 weight part, stabilization and usability of a moisturizing agent can be inhibited. In addition, volatile oils (cyclic or chain silicone, isoparaffin) are used to represent the persistence in the lipstick of the present invention. The volatile oils may exhibit satisfactory persistence in the range of 0.1 to 60 parts by weight.

The chain silicone oil used in the present invention is preferably a volatile low viscosity dimethylpoly siloxane having a viscosity of 0.65 to 1.5 centistokes, and the cyclic silicone oil has the following structure.

n=3-6

n = 3-6

Isoparaffins are also suitable for 10-20 carbon atoms. In this invention, said volatile oil can be used individually or in combination of 2 or more types. In addition, silicone resins such as trimethylsiloxy silicate can be used to further improve the durability, and waxes, semi-solid and liquid oils, sunscreens, discoloration inhibitors, pigments, and oxidative stabilizers generally used in lipsticks can be used. Appropriate amount can be used as needed.

Lipstick composition of the present invention composed of the composition as described above is composed of galactosyl ceramides, cholesterol, moisturizers, etc., without using a surfactant that irritates the hydrophilic moisturizing agent that is difficult to stabilize extremely conventional conventional lipsticks and persistent lipsticks It is a lipstick composition which combines a large amount of moisturizers and moisturizing ingredients stably in a lipstick base showing sustainability by forming a highly moisturizing complex, and simultaneously combines sustainability and high moisturizing effects that were not expected with conventional lipsticks.

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