Description

Long-wearing lipstick composition

The present invention relates to a long-wearing lipstick composition having excellent stability and moisturizing properties, and more particularly, to a persistent lipstick composition using bentonite or hectorite gel base.

In general, the lipstick is composed of an oily wax, oil and pigment, and has been mainly used to give a softening effect to the lips and to express various colors. Since the early 1990s, various persistent lipsticks have been developed to improve the shortcomings of ordinary lipstick, which is the biggest complaint of users. However, in these studies, efforts have focused solely on that persistent lipsticks should not be smeared, leading to further problems with dry lips and product stability. There are two types of such conventional non-permanent persistent lipsticks.

First, there is a lipstick composition prepared by mixing a volatile oil with a film-forming polymer, wax, powder, and the like. This product has excellent sustaining effect after lip application, but it is relatively waxy and powder as the volatile oil is volatilized after time. Too much content had the disadvantage of drying lips.

Another lipstick composition is a lipstick composition prepared by mixing an organosiloxane resin, a high viscosity dimethicone, and a volatile oil, which, after the volatile oil has been volatilized, prevents moisture from evaporating on the lips and does not contain wax. The lip dryness was improved, but the compatibility of the mixture was poor, and there were problems in stability, such as separation of contents due to changes over time. In particular, due to these problems, not only the formulation of the lipstick, but also the form, storage condition, handling, and the like of the container have various restrictions.

On the other hand, looking at the conventional persistent lipstick composition around the patent application there are the following. European Patent Publication No. 94-602905 proposes a persistent cosmetic composition which uses a large amount of a volatile solvent and a silicone resin and in addition contains a wax, an oil and a pigment component, and has a low rusting effect. Japanese Patent Laid-Open No. 94-287109 describes a lipstick containing dipropylene glycol, an oil-soluble monohydric alcohol, and a tar colorant, but by using the same oily base as a regular lipstick, the sustainability of the lipstick Did not raise. In addition, Japanese Patent Publication Nos. S61-83110 and US Pat. No. 5,085,856 describe a lipstick composition containing water using an appropriate emulsifier, but there is a problem in long-term storage stability as well as volatilization of the water in forming the lipstick. It was difficult for water to exist in the final product. In addition, in International Patent Publication Nos. 94-06401 and 94-06400, lipsticks containing a large amount of moisturizing agents have been proposed, but for this purpose, the amount of surfactant or the like used increases the skin irritation and the persistence is reduced. In recent years, Korean Patent Application No. 97-59510 has developed a lipstick composition which stabilizes moisturizing ingredients using galactosyl ceramide and cholesterol, but this also shows satisfactory effects in both persistence, moisturizing and stability. Could not.

Accordingly, there has been a demand for the development of a lipstick composition that is excellent in both non-stainability, moisturizing to prevent dry lips and stability without separation.

In order to solve the above problems, the present invention improves the separation of contents due to changes over time, and the flexible film film adhered to the lips prevents water evaporation, thereby improving the dryness of the lips after a period of time, as well as crowded places or crowded places It is an object of the present invention to provide a persistent lipstick composition that eliminates the need for correction cosmetics by preventing the lipstick from smearing when drinking or eating coffee.

In addition, another object of the present invention is to provide a lipstick composition having excellent sustainability stabilized by the blending composition itself without resorting to a container or a preservation method of a separate lipstick.

The present invention specifically prepares a base in which bentonite or hectorite and a volatile oil are stabilized in a gel state, and then the base is mixed with an organosiloxane resin, high viscosity dimethicone, powder, etc. It is another object to provide the composition.

Still other objects of the present invention will be realized through the following configurations and examples of the present invention.

1 is a graph showing the results of measuring the duration of time after applying the lipstick of the Examples and Comparative Examples of the present invention using a color difference meter.

Figure 2 is a photograph comparing the degree of buried in the embodiment of the present invention and the comparative example by a tissue identification method.

3 is a photograph comparing the degree of buried in the embodiment of the present invention and the comparative example using a cup.

In order to achieve the above object, the present invention provides a gel base for producing a persistent lipstick comprising 2 to 10% by weight of bentonite or hectorite, 0.5 to 5% by weight of ethanol and the remaining amount of volatile oil.

In another aspect, the present invention provides a persistent lipstick composition, characterized in that it comprises 10 to 50% by weight of the gel base, the composition is a mixture with an organic siloxane resin, high viscosity dimethicone, powder as the remaining amount specifically It includes, but the organic siloxane resin in the mixture is included in the range of 5 to 50% by weight, high viscosity dimethicone 1 to 30% by weight, powder 3 to 20% by weight based on the total weight of the composition.

The organosiloxane resin used in the present invention has a molecular weight of 2,000 to 3,000, a ratio of (CH ₃ ) SiO _1/2 unit: SiO ₂ unit of 0.8: 1.0, and an average formula (CH ₃ ) _1.33 SiO _1.34 and (CH ₃ ) SiO _1/2 / SiO ₂ / (CH ₃ ) SiO _3/2 units of 44.0 / 55.0 / 1.0, or (CH ₃ ) SiO _1/2 units: SiO ₂ units of 1.5: 1.0 ₃ ) It is possible to have _1.8 SiO _1.1 and (CH ₃ ) SiO _1/2 / SiO ₂ / (CH ₃ ) ₂ SiO / (C ₆ H ₅ ) SiO _3/2 to be 1.6 / 3.1 / 1.0 / 1.0. The resin is soluble in organic solvents such as toluene, xylene, isoparaffin, cyclosiloxane, volatile carrier, etc., but is not fully bound.

Examples of the organosiloxane resin may include a product sold under the names Dow Corning 749, Wacker 803, 804, and G.E 1170-002.

Such organosiloxane resin should be used at least 5% by weight. If it is used below, the persistence function decreases, so that it becomes more smeared after applying the lip, and when the 50% or more is used, the coating film becomes thick, giving a heavy feeling over time, which may put a burden on the lips.

In addition, the high viscosity dimethicones used in the present invention are those having a viscosity of 1,000 to 2,500,000 cSt (centistokes) at 25 ° C. Particularly suitable are poly (dimethylsiloxanes), also called PDMS. When the content is used in less than 1% by weight, the flexibility of the coating film is reduced, the color persistence is lowered, when using more than 30% by weight is difficult to apply the dispersion.

In the present invention, a silicone oil may be used as the volatile oil used in the preparation of the gel base mixed with the organic siloxane resin and the high viscosity dimethicone. After applying lipstick, the silicone oil quickly evaporates from the surface of the lips, making it easy to create a thin, flexible film.

As the silicone oil, volatile hydrocarbons, volatile silicones and mixtures thereof are used.

Hydrocarbon oils include C ₈ to C ₂₀ isoparaffin, isododecane, isohexadecane, isoic acid, 2,2,4-trimethylpentane, 2,3-dimethylhexane and mixtures thereof. Among them, Creasil IDCG products which are commercially available from Creations Couleur (Isa) as isododecane are most preferred. The structural formula of the product is as follows.

Another usable volatile silicone is cyclomethicone having a regular structure of 3, 4, 5, and the structural formula is as follows.

Wherein X is 3 to 6

Dow Corning's DC244, 245, and 345 are available commercially.

When the silicone oil is used at 10% or less, it takes a long time for the sustaining function to be exhibited due to the slow drying speed after application, and when used at 70% or more, it is difficult to be mixed due to poor compatibility with organic siloxane resin and high viscosity dimethicone. It can also cause dry lips after application.

In addition, as the bentonite and hectorite used to improve the phenomenon that the contents are separated by time-dependent change, which is a disadvantage of the prior art, quaternium-18 bentonite, quaternium-18 hectorite ( Quternium-18 Hectorite), montmorillonite derivatives, and the like, and a product sold under the trade names Clayton S and Clayton SO by Laporte, is preferred.

When the component is used at 0.5% or less relative to the total weight of the gel base, it does not help to improve the separation phenomenon, which is a disadvantage of the conventional product, and when it is used at 10% or more, the viscosity of the content rapidly increases, resulting in a drop in the feeling of use.

In addition, the powder used in the present invention can be any powder generally used in cosmetics. For example, silica, talc, mica, kaolin, magnesium carbonate, calcium carbonate, aluminum silicate, magnesium silicate, calcium silicate, titanium oxide, zinc oxide, silicic anhydride, bengal, iron oxide, ultramarine, tar color, natural pigment, Mica titanium, iron oxide mica titanium, nylon powder, silk powder, polyethylene powder, silicon powder, and the like.

In addition to the above essential components, various optional components used in ordinary cosmetics, such as perfumes, preservatives, ultraviolet absorbers, and the like, can be blended in a range that does not interfere with the effects of the present invention.

In addition, the present invention provides a method for producing a persistent lipstick composition using the gel base, specifically, 2 to 10% by weight of bentonite or hectorite, 0.5 to 5% by weight of ethanol and the remaining amount of volatile oil by mixing and stirring the base of the gel state Preparing a; And mixing and stirring the gel base in a range of 5 to 50% by weight of an organic siloxane resin, 1 to 30% by weight of a high viscosity dimethicone, and 3 to 20% by weight of powder to the gel base. It is done.

As such, the present inventors have developed a lipstick composition using a base in which a volatile oil is stabilized in a gel state using bentonite or hectorite, thereby developing a new concept of a persistent lipstick which improves the separation of contents due to the change of the conventional time. Through this, it was possible to extend the range of use of the lipstick.

As shown in the results of Table 6 and Figure 1, compared to the lipstick composition of the comparative example, it can be seen that the color persistence is excellent as the color change over time after the application of the lipstick composition of the example is less.

As described above, in the persistent lipstick composition of the present invention, a gel base is prepared using bentonite or hectorite as a volatile oil, and then the lipstick composition is prepared using the base, thereby improving the separation phenomenon due to the change in the conventional time. Of course, the permanent lipstick's inherent function is improved, and the wider use becomes possible.
