Description

Water-in-oil emulsion cosmetic composition for lips with excellent gloss, moisturizing and sliding feeling}

The present invention relates to a cosmetic composition, and more specifically, a water-in-oil type emulsion containing a first oil and a second oil to impart high moisturizing power and a light sliding feeling while containing an oil-soluble film former to increase excellent glossiness and durability Lip emulsion It is about a cosmetic composition for use.

In general, among cosmetic compositions for lips, the emulsifier type has water as the external phase and oil-in-water (O/W) emulsion in which oil is dispersed therein, and conversely, oil is used as the external phase and water is in the middle. There is a Water-in-Oil (W/O) emulsion, which is dispersed in water, and an oil-dispersion formulation consisting only of oily ingredients.

Since there are no sebaceous glands in the case of the lips, the O/W emulsifier-type cosmetic composition for lips can give dryness to the lips through immediate moisture evaporation when applied to the lips. Compared to , it can provide a moisturizing feeling, but it has weak color persistence, stickiness, stuffiness, and easily erased.

In order to secure it, a method of using a film forming agent was devised to increase the durability. However, due to the characteristics of lips with a lot of movement and a lot of wrinkles when the film former is applied, disadvantages such as hardening and cracking, poor application properties, and uncomfortable feeling of use occur.

In addition, oil is used to increase the refractive index, but oil adheres to the lips and has a sticky feeling and heavy sliding feeling on the lips, so consumer preference tends to drop.

In order to solve this problem, Patent Document 1 of the prior art documents discloses a cosmetic composition for lips containing an acrylic film forming agent and a volatile oil. However, Prior Art Document 1 does not overcome the problem of feeling of use or spreadability felt when applying a product using a large amount of film forming agent to the lips.

In addition, Patent Document 2 discloses a cosmetic composition for lips containing fluorine-based oil, fluorine-based silicone wax, and volatile oil. Here, smearing and dryness were improved by using fluorine-based oil and fluorine-based silicone wax, and sensory evaluation for applicability was also conducted, but it is a dispersing formulation rather than an emulsifying formulation, and there is a problem that evaluation of glossiness is insufficient.

In addition, Patent Document 3 discloses an emulsion type makeup cosmetic composition that improves formulation stability in a water-in-oil emulsion makeup product and provides a type formulation with excellent gloss and moisturizing power. To this end, it contains Hydrogenated Polyisobutene, Tridecyl Trimellitate and Polybutene, but there is a problem in that evaluation of stickiness and persistence has not been made.

Registered Patent No. 10-211911, Title of Invention: Emulsion cosmetic composition for lips Registered Patent No. 10-2178965, Title of Invention: Cosmetic composition for lips with improved durability and dry feeling {Cosmetic composition for lips with improved durability and dry feeling} Registered Patent No. 10-2102592, Title of Invention: Emulsion type Makeup Cosmetic Composition

The present invention is to solve the problems of the prior art, and an object of the present invention is to improve the gloss of the lips by using raw materials forming a film in an optimal ratio in the formulation, and to provide soft application and moisturizing power without stickiness. It is to provide a stable water-in-oil cosmetic composition for lips.

The water-in-oil emulsion cosmetic composition for lips according to the present invention has a feeling of use that is applied by sliding smoothly without stickiness while having a high gloss. In addition, the present invention can improve dryness, a disadvantage of oil-in-water type formulations, by using oils with good water trapping properties for external use to impart an excellent feeling of moisture to the lips.

Accordingly, the water-in-oil emulsion cosmetic composition for lips according to the present invention includes an oil phase and an aqueous phase, and the oil phase includes an oil-soluble film-forming agent and an oil, and the oil-soluble film-forming agent is used in an optimal ratio to maintain gloss and moisture of the lips. effect can be maximized.

The oil-soluble film-forming agent may be at least one selected from silicone-based resins, PVA-based resins, acrylamide-based resins, and celluloses. However, it is not limited thereto.

More preferably, the oil-soluble film forming agent is more preferably a silicone-based resin in terms of expressing an excellent gloss effect while increasing color retention on the lips without being sticky.

At this time, the silicone-based resin preferably contains 3.00 to 9.00% by weight of polypropylsilsesquioxane and trimethylsiloxysilicate based on the total weight of the cosmetic composition. If the content of polypropylsilsesquioxane and trimethylsiloxysilicate is less than 3.00% by weight, the film forming effect is hardly shown and color and glossiness are not maintained on the lips. This is because the longer the time, the stickiness and hardening and cracking appear, and as a result of observing the stability by temperature, phase separation and abnormality of properties are shown at high temperatures and cycles.

On the other hand, in the water-in-oil emulsion cosmetic composition for lips according to the present invention, the oil can easily dissolve the oil-soluble film-forming agent, can increase the spreadability of the formulation, which can be inhibited when used in large amounts, provides moisturizing and glossiness, and provides excellent sliding It is not limited as long as it adds persimmon, but may be one or more selected from hydrocarbon-based oils, higher fatty acid-based oils, ester-based oils, glyceride-based oils, polyglyceryl fatty acid ester-based oils, and silicone-based oils.

More preferably, the oil preferably comprises a first oil for imparting a sliding feeling and a second oil for imparting a moisturizing feeling. In this case, the first oil may be a hydrocarbon-based oil, and the second oil may be a polyglyceryl fatty acid ester-based oil.

At this time, in terms of imparting an excellent sliding feeling, the first oil preferably contains at least one selected from isododecane, isohexadecane, isoeicosane, and hydrogenated polyisobutene among hydrocarbon-based oils, and isoeicosan and Those containing hydrogenated polyisobutene are most preferred.

Furthermore, when the content ratio of isoeicosic acid and hydrogenated polyisobutene is similarly formed, the effect of improving spreadability at the time of application, reducing stickiness, and maintaining moisturizing power is further expressed. Although isoeicosan shows a great effect in imparting an excellent sliding feeling, it is not free from stability problems such as formulation separation when used in excess, so it improves stability and sliding feeling by using a similar content ratio of hydrogenated polyisobutene that improves spreadability effect can be shown. In addition, hydrogenated polyisobutene is a hydrocarbon polymer obtained by adding hydrogen to polyisobutene, and may block moisture evaporation on the skin to give an additional effect on moisturizing power.

At this time, the hydrocarbon-based oil preferably contains 8.00 to 11.00% by weight based on the total weight of the cosmetic composition. If the content of hydrocarbon-based oil is less than 8.00% by weight, it does not give a slippery feeling when applied, and if it exceeds 11.00% by weight, the viscosity is very low and phase separation occurs within 24 hours after preparation of the formulation. .

On the other hand, in this case, isoeicosan is preferably contained in an amount of 3.0 to 6.0% by weight based on the total weight of the water-in-oil emulsion cosmetic composition. If it is less than 3.0% by weight, the viscosity of the formulation is higher than before and it is difficult to impart an excellent sliding feeling, and if it exceeds 6.0% by weight, a stability problem occurs in which phase separation occurs at room temperature when the stability is checked the next day after manufacture.

In addition, in order to sufficiently provide a moisturizing feeling and increase the stability of the formulation, the second oil is polyglyceryl fatty acid ester-based oil such as polyglyceryl 2 isostearate, polyglyceryl-2 diisostearate, and polyglyceryl-2 triglyceride. It is preferably at least one selected from isostearate, polyglyceryl-10 decaisostearate, and the like, and most preferably polyglyceryl-10decaisostearate.

In the case of polyglyceryl-10 decaisostearate, it is a polyglyceryl fatty acid ester-based oil similar to liquid lanolin in terms of water retention and water evaporation prevention ability. can contribute

In addition, it is preferable to contain 5.00 to 15.00% by weight of the second oil based on the total weight of the cosmetic composition. If the polyglyceryl fatty acid ester oil is less than 5.00% by weight, the moisturizing power is significantly reduced and the pigment dispersion is lowered, resulting in separation of the pigment band during formulation preparation. This is because the satisfaction in terms of usability is lowered compared to the insignificant difference in .

On the other hand, in the present invention, the oil-soluble film forming agent and oil may be used in an amount of 46 to 58% by weight based on the total weight of the composition, but is not limited thereto. The former and oil may be mixed in a weight ratio of 1:1 to 1:3.

At this time, by mixing the oil-soluble film-forming agent and oil in the above-described weight ratio, the problems of existing oil-dispersible formulations, such as stuffiness and sticky feeling during application, were solved, and dryness, a problem of oil-in-water lip cosmetics, was improved. In addition, the feeling of use was greatly improved by solving the hard and sticky feeling that may occur in formulations using a large amount of an oil-soluble film former to increase color durability and gloss.

Meanwhile, the water-in-oil type emulsion cosmetic composition for lips may further contain dipropylene glycol.

The water-in-oil emulsion cosmetic composition for lips according to the present invention makes the lips look glossy with an excellent glossiness and provides an excellent moisturizing feeling to the lips, thereby eliminating discomfort that may be felt during makeup use.

In addition, the water-in-oil emulsion cosmetic composition for lips according to the present invention has improved application power due to high spreadability, and can have remarkably improved feeling of use due to the use of a film former with good air permeability.
