Description

Water-In-Oil Type Emulsion Liquid Rouge Composition

1 is a manufacturing process of the water-in-oil emulsion liquid loose composition according to the present invention.

Figure 2 is a photograph of the emulsion particles of Example 2 according to the present invention.

The present invention relates to a water-in-oil emulsion liquid loose composition. The water-in-oil emulsion liquid loose composition according to the present invention stabilizes a large amount of water even without the use of a general emulsifier, and despite the moisture content, it does not significantly affect the gloss, the feeling of use, and the stability seen in the general anhydrous liquid loose, The makeup is natural and good, and after the application of the lips, moisture acts as a volatile solvent, and the polymer is set on the lips for a long lasting color.

In general, the emulsification technology is widely applied in various industries such as medicine, food, cosmetics. The emulsification technique is a thermodynamically unstable state that allows the two liquids that are not mixed to remain in a stable state for a certain period of time by controlling the interfacial tension. Therefore, the emulsification method or the emulsification conditions are very different depending on the two phases of the emulsion and the kind of the surfactant, and thus the state of the resulting emulsion may be different. According to the purpose of the product, it is very important to ensure the stability of the product to make an emulsion with an appropriate emulsion particle size and particle distribution evenly distributed.

In the case of conventional lip cosmetics, especially liquid rouge composition is anhydrous oil-dispersion formulation is all. The first component is candelillanab, ceresin, carnauba wax, paraffin, wax, braze, beeswax, microcrystalline lead, polyethylene, etc., to increase the hardness to maintain the appearance form of the lip cosmetic composition, the second Many types of liquid oils such as low squalane, lanolin oil, lanolin derivatives, plant-derived oils, synthetic ester oils and silicone oils, and thirdly, high viscosity polybutenes, polyisobutenes, hydrogenated polybutenes, hydrogenated polys High viscosity polymers such as hydrocarbon polymers such as isobutene, high viscosity esters, high viscosity ethers, high viscosity silicones and high viscosity alkylsilicones, urethanes and urethane silicones; Other ingredients, such as potent ingredients such as inhibitors, preservatives, fragrances and other extracts.

The liquid phase loosening of the oily base is prepared by a method of dispersing the pigment and the colorant evenly after melting at high temperature. Such a liquid luster with good general gloss is characterized by containing a large amount of polymer, and containing a large amount of such polymer has an advantage of excellent gloss, but due to its high viscosity, the coating film gives a thick, stuffy and sticky feeling on the lips. In addition, the liquid type has the disadvantage that the oil component spreads between the wrinkles of the outer lip, messy and blurred color.

In order to show a fresh feeling in the makeup cosmetics compared to the general dispersing formulation, an aqueous dispersion, an oil-in-water type or a water-in-oil type emulsion formulation is generally used. Dispersed formulations and oil-in-water types give a natural, refreshing feel, but they contain large amounts of water, causing severe damage in gloss and persistence, and also drying the lips as the water evaporates.

On the other hand, the water-in-oil type gives a fresh and refreshing feeling and durability. However, the general formula of water-in-oil emulsion is composed of solid components, low viscosity ester and silicone oils, pigments and high surfactants and dispersants such as candelillan, ceresin, carnauba wax, microcrystalline lead and polyethylene. And oily ingredients such as purified water, moisturizers, thickeners, various potency ingredients and salts. These emulsion formulations are mainly composed of low viscosity components, have a low gloss, have a very thin coating film, and in general, water-in-oil cosmetics are often formulated with a high content of powder, and in this case, it is easy to bring dry lips. In addition, the presence of a large amount of surfactant increases the likelihood of irritating sensitive lips, re-emulsified with the moisture of saliva and lips, which may lead to a cloudy feeling and foreign body. In addition, the feeling of use of the lip cosmetics is greatly affected.

The components of the oil-dispersed liquid loose component described above and the components of the general water-in-oil emulsion cosmetics are greatly different in terms of the difference in the viscosity of the components used, the use of a large amount of emulsifiers, and the like. It is not suitable for preparing cosmetics, and in particular, it is more difficult to prepare a water-in-oil type liquid rouge that can give gloss and refreshing feeling to the lips while having excellent stability. Therefore, there is a need to improve the manufacturing method according to the use characteristics of the product.

On the other hand, attempts have been made to secure the stability of an emulsion using an oil soluble thickener as an emulsified lip cosmetic composition. Specifically, Japanese Patent Application Laid-Open Nos. Hei 1-168607 and Hei 7-267826 describe a water-in-oil lip cosmetic composition in which dextrin higher fatty acid esters, polybutenes (average molecular weight 500 to 5000) and multi toll are blended. Doing.

Accordingly, the present inventors have studied to prepare a water-in-oil emulsion liquid loose composition exhibiting excellent gloss and refreshing feeling while solving the disadvantages of general liquid loose, and resulted in re-emulsification due to emulsifier in the lips in high viscosity ester oil, high viscosity polymer and purified water. In order to solve problems such as adhesion and gloss reduction, when the self-emulsifying silicone gel having a lipophilic group and a hydrophilic group is used instead of an emulsifier, it was confirmed that the emulsion exhibits excellent gloss, refreshing feeling, and spreadability while stabilizing the emulsion.

Furthermore, the present inventors set the optimum emulsification temperature, the order of the emulsion, the emulsion time, the emulsification rate, and the like, based on a general method for preparing a water-in-oil emulsion, and the emulsion-in-oil emulsion liquid loose composition. The manufacturing method of this invention was discovered and this invention was completed.

Accordingly, it is an object of the present invention to provide a water-in-oil emulsion liquid loose composition exhibiting excellent gloss, freshness and spreadability.

In order to achieve the above object, the water-in-oil emulsion liquid loose composition according to the present invention comprises (a) a high viscosity ester oil, (b) a high viscosity polymer, (c) a self-emulsifying silicone gel and (d) purified water It is done.

In the present invention, the high viscosity ester oil (a) is an ester oil of 4,000 mPa · s / 20 ° C. or more, and the high viscosity polymer (b) is preferably a polymer of 20,000 mPa · s / 20 ° C. or more.

The water-in-oil emulsion liquid loose composition according to the present invention preferably contains (a) 1 to 30% by weight of a high viscosity (4,000 mPa.s / 20 ° C) ester oil based on the total weight of the composition, and (b) a high viscosity (20,000 mPa). s / 20 ° C. or more), preferably 1 to 50% by weight of the polymer, (c) 0.5 to 9.0% by weight of the self-emulsifying silicone gel, and (d) 30 to 60% by weight of purified water. desirable.

The high viscosity ester oil (a) used in the present invention is an ester-based oil having high refractive index and high gloss, which gives gloss of lips and prevents moisture loss. Since the said (a) component influences glossiness when viscosity is low, high viscosity of 4,000 mPa.s / 20 degreeC or more is preferable. In addition, the high viscosity ester oil (a) is contained in an amount of 1 to 30% by weight, preferably 5 to 20% by weight based on the total weight of the composition, which is lowered in gloss of the final content when the content is less than 1% by weight. If it exceeds 30% by weight, it is because it affects the feeling of use. Specific examples of the (a) high viscosity ester oil include triisostearin, polyglyceryl triisostearate, diisostearyl malate, polyglyceryl diisostearate, octyldodecylstearoylstearate, and the like.

The high viscosity polymer (b) used in the present invention is a component that helps to improve gloss and durability, and specifically, a hydrocarbon polymer such as high viscosity polybutene, polyisobutene, hydrogenated polybutene, hydrogenated polyisobutene, and high viscosity ester , High viscosity ethers, high viscosity silicones and high viscosity alkylsilicones, acrylics, acrylic silicones, urethane polymers, urethane silicone polymers and the like. In the present invention, the high viscosity is preferably 20,000 mPa · s / 20 ° C. or higher, and the polymer (b) the high viscosity polymer is contained in an amount of 1 to 50% by weight, preferably 10 to 30% by weight, based on the total weight of the composition. This is because when the content is less than 1% by weight, it is not preferable for gloss and lasting stability, and when it exceeds 50% by weight, it affects stability and usability.

Self-emulsifying silicone gel (c) used in the present invention is a silicone thickening polymer that acts as an emulsifier, has an amphiphilic property, gives a smooth feeling and plays an important role in stability and feeling. The (c) self-emulsifying silicone gel is contained in 0.5 to 9.0% by weight, preferably 1.5 to 4.5% by weight relative to the total weight of the composition. This is because when the content is less than 0.5% by weight, the content is low, which adversely affects the stability of the emulsification. When the content is more than 9.0% by weight, the gloss or the feeling of use decreases, and the viscosity is too high, so that uniform mixing is difficult during the emulsification process. (c) Self-emulsifying silicone gels specifically include dimethicone / pig-10-10 / 15 crosspolymers, fig-15 / lauryl dimethicone crosspolymers, and fig-10 / lauryl dimethicone crosspolymers.

(D) Purified water used in the present invention is a component that plays a major role in the freshness and freshness of the main purpose of the present invention. It is preferable to contain 30 to 60% by weight relative to the total weight of the composition because it affects stability and usability depending on the change in content.

Hereinafter, a method for preparing a water-in-oil emulsion liquid loose composition according to the present invention will be described in stages:

(1) primary homogenization while stirring the oil phase containing component (a) high viscosity ester oil, (b) high viscosity polymer, and the like; (2) after the coloration process, adding the component (c) self-emulsifying silicone gel to secondary homogenization; (3) warming to 80 ° C. while stirring the aqueous phase containing component (d) purified water; (4) slowly emulsifying the water phase of the step (3) to the oil phase of the step (2); (5) adding a fragrance component and proceeding with the first defoaming simultaneously with the end of emulsification; (6) proceeding with cooling while adjusting the paddle speed of the paddle mixer and then performing complete defoaming at 50 ° C; And (7) cooling to 35 ° C. or less.

The first homogenization of the step (1) is preferably heated and dissolved at 90 ~ 95 ℃ while stirring at 3600 rpm.

The second homogenization of step (2) is preferably heated and stirred at 80 to 85 ° C. for at least 5 minutes. If the temperature is less than 80 ℃ high viscosity of the content during the manufacturing is difficult to evenly mix and emulsify, degassing is not made properly can seriously affect the stability.

The stirring in the step (3) is carried out at 500 ~ 600 rpm.

The emulsification of the step (4) is emulsified at 80 ℃ for 5 minutes while stirring at 2200 ~ 2400 rpm to prepare a water-in-oil emulsion, and then stabilize the emulsion particles by component (c). At this time, when the emulsification time is long or the emulsification rate is high, the viscosity of the contents is greatly increased, so that defoaming is not performed.

The process chart of the said (1)-(7) step is shown in following FIG.

The water-in-oil emulsion liquid loose composition according to the present invention is prepared by setting the time, temperature, stirring speed, etc. in each step to the optimum conditions in the above steps (1) to (7), thereby exhibiting excellent glossiness and freshness. An emulsion liquid loose composition is prepared.

[Test Example 1]

In order to evaluate the stability of the water-in-oil emulsion liquid loose prepared in Examples 1 to 3 and Comparative Examples 1 to 3, high temperature (45 ° C) stability and cycling test (0 to 45 ° C, 6 cycles per day), shaking The test (150-200 rpm) was done. The results were visually evaluated and shown in Table 2 below.

As can be seen from Table 2, it was confirmed that Examples 1 to 3 exhibited excellent overall stability.

[Test Example 2]

In order to compare the ease of use of the liquid rouge prepared in Examples 1 to 3 and Comparative Example 2 was applied to 20 women in their 20s to 30s, the following items were evaluated on a 5-point scale.

(Evaluation item)

Cool / Glossy / Spread (Overall Feel)

(Evaluation standard)

1 point: Very bad, 2 points: Bad, 3 points: Normal, 4 points: Good, 5 points: Very good

Example 1 Example 2 Example 3 Comparative Example 2 Refreshing feeling 3.5 3.8 3.2 4.8 Polish 3.8 3.6 4.0 2.8 Spreadability (Overall Usability) 3.1 4.2 3.5 2.8

As can be seen in Table 3, it was confirmed that the higher the water content as in Example 1, the smaller the content of the thickener in the emulsifier role as in Examples 1 and 2 receives a higher score in the refreshing feeling. However, in the case of Comparative Example 2, the emulsification is more unstable, the emulsified particles are easily broken during application, resulting in a strong refreshing result, but the overall usability such as gloss was not good, and the stability was particularly unstable. In addition, as shown in Example 3, the higher the polymer content, the higher the score in gloss, but it was confirmed that the score is slightly reduced in the refreshing feeling or the wearability. In addition, the spreadability was confirmed that the higher the content of water and the less the polymer content, the rating score increases, and therefore, the evaluation result of Example 2 is the best.

As described above, the water-in-oil emulsion liquid loose composition according to the present invention contains more than 30% of water phase components and contains self-emulsifying silicone gel, which is very stable in appearance and usability and has a refreshing feel and excellent gloss and spreadability during makeup. In addition, since no emulsifier is used, it is possible to have a fresh lip makeup that is not burdensome.
