[Name of invention]

High Moisturizing Lipstick Composition

Detailed description of the invention

[Purpose of invention]

The present invention relates to a lipstick composition having a high moisturizing effect, and more particularly, by combining a moisturizing component such as galactosyl ceramide and cholesterol and polyhydric alcohol, and stably compounding a large amount in the lipstick composition, which was not expected in a conventional lipstick. The present invention relates to a lipstick composition having an excellent moisturizing effect and an excellent sustaining effect.

[Technical field to which the invention belongs and the prior art in that field]

In general, conventional lipsticks are composed of waxy oils and pigments, which are oily ingredients. Among them, oily ingredients give lips softness, proper gloss and feel, and express various colors by combination of various pigments. will be.

The physiological characteristics of the lips are known to have almost no stratum corneum compared to normal skin (extremely thin), so that the loss of moisture on the surface of the lips is known to be six times faster than the skin, which makes the lips easier to dry, especially in dry climates. This may cause phenomena. However, since the existing lipstick uses an oil-based component composed of oil and wax as a periodic agent, only a simple physical shielding film is formed on the surface of the lips, so a great moisturizing effect could not be expected.

For this reason, various attempts have been made to impart a moisturizing effect to the lips to date, and a conventional technique for improving the moisturizing properties of the lipstick is as follows.

Japanese Patent Application Laid-Open No. 61-836110 discloses a composition that imparts a moisturizing effect to the lips by emulsifying water in wax water and oil components using a dispersant such as cholesterol, phytosterol, phospholipid and anions, cations, nonions, and amphoteric surfactants. Is proposing. U.S. Patent No. 5,085,856 (published April 92) also points out that the invention has a storage stability problem and proposes a lipstick composition in which water is stabilized using an appropriate type of emulsifier.

However, since the lipstick composition containing the water has a problem of long-term storage stability and water is actively volatilized at the filling temperature (about 80 ° C.) during the molding of the lipstick, it is not necessary to stably mix the water with the final molded lipstick. impossible.

As anhydrous lipstick composition, U. S. Patent No. 2,853, 422 proposes to disperse water-soluble dyes in propylene glycol, polyethylene glycol, and resiole, and U. S. Patent No. 5,034, 216 contains powder, oil phase and ethylene / acrylate copolymers. Lipstick compositions have been proposed, but are also insufficient to impart sufficient moisturizing effect to the lipstick.

In addition, International Patent No. 94-06041 attempts to stabilize a large amount of moisturizer in a lipstick composition using a coupling agent of an oil and a moisturizer such as glyceryl oleate / propylene glycol (1: 1) glyceryl monostearate. Patent No. 94-06400 attempts to stabilize a moisturizer with surfactants and lecithins having a kraft point below room temperature, such as sorbitanate and sorbitassesquioleate.

However, inevitably, the surfactant and coupling agent used at this time could not exclude the possibility of causing some irritation to the lips skin having an extremely thin keratin structure.

[Technical problem to be achieved]

Accordingly, the present inventors have conducted a number of studies and experiments to solve the above-mentioned problems of the prior art, and as a result, a moisturizer that is generally extremely difficult to mix in a lipstick composition composed of an oil and a wax is similar to a keratin component having moisture evaporation control function in the skin. By complex stabilization using galactosyl ceramide and cholesterol, which have a structure, a high moisturizing lipstick composition with excellent moisturizing effect is formulated by stably blending a large amount of moisturizers without using any surfactant that may cause irritation. Was done.

[Configuration and Function of Invention]

The present invention relates to a high moisturizing lipstick composition comprising a moisturizer base consisting of calactosyl ceramide, cholesterol, polyhydric alcohol and liquid oil.

The lipstick composition according to the present invention comprises 0.1-70% by weight of a moisturizer base composed of 1-70% by weight of calatosyl ceramide, 0.1-50% by weight of cholesterol, 0.1-90% by weight of polyhydric alcohol and 0.1-50% by weight of liquid oil. And, in addition, steaalconium hectorite and solidifying agent wax and common oil components.

The galactosyl ceramide used in the moisturizer base exhibiting a moisturizing effect in the lipstick composition of the present invention is a component having a similar structure to the keratin component having moisture evaporation control function of the skin and shows a great effect in stabilizing the hydrophilic moisturizer. Lipstick is applied to the lips to form a lipid film on the surface of the lips to increase the color persistence effect. It is preferable to use 1-70% by weight of galactosyl ceramide in the base of the moisturizer, and when the content is less than 1% by weight, the polyhydric alcohol (eg, glycerin, 1,3-butylene glycol), which is a moisturizer, is effectively used. Not only do not stabilize in the lipstick, it is difficult to expect the moisturizing effect of the galactosyl ceramide itself, the viscosity of the moisturizer base itself is too high when more than 70% by weight, it is not easy to remove the excess bubbles generated during manufacture.

It is also preferable to use 0.1 to 50% by weight in the moisturizer base used in the present invention. If the amount of cholesterol used is 0.1% by weight or less, the effect of stabilizing the moisturizer and the solubility of the galactosyl ceramide in the moisturizer base is not sufficiently enhanced, and the viscosity of the moisturizer base is too high at 50% by weight or more, which is not good.

Liquid oils are used at room temperature. Hydrocarbon-based oils, ester-based oils and higher alcohols that are commonly used in lipsticks can be used. The use amount of oil is preferably 0.1-50% by weight, can be adjusted for the viscosity and moisturizing effect of the base within the above range, it is difficult to expect the stabilization of the moisturizer at 50% by weight or more.

In the lipstick composition of the present invention, by using a moisturizer base composed of the above components in an amount of 0.1-70% by weight, the moisturizing effect can be imparted to the lipstick as necessary. When the moisturizer base is used in an amount of 0.1 wt% or less, the moisturizing effect is not sufficient, and when the moisturizer base is used in excess of 70 wt%, the moisturizer may be stabilized, the color expression of lipstick and the usability may be impaired.

In addition, the lipstick composition of the present invention can be used by adding a dispersant such as waxes, oils, pigments, sunscreens, film formers and stearconium hectorite in addition to the moisturizer base component described above. have.

Lipstick composition of the present invention composed of the composition as described above is a complex composed of galactosyl ceramide, cholesterol, liquid oil and the like a friend moisturizing agent (e.g. glycerin, 1.3 butylene glycol), which is extremely difficult to blend in conventional lipstick As a phosphorus moisturizer base, it is a lipstick composition which shows a superior moisturizing effect and excellent stability compared to existing lipsticks by stably blending a large amount of moisturizer with lipstick without using any irritating surfactant.

Hereinafter, the present invention will be described in more detail based on Examples and Comparative Examples, but the technical scope of the present invention is not limited thereto.
