Cosmetic composition for lips {LIP COSMETIC COMPOSITION}

This description relates to a cosmetic composition for lips.

As aging progresses, the bright red lip color changes to dull and dark, and the lips become thinner and poorer. Therefore, in order to improve the dullness and thinness of the lips, there is a lot of interest in creating vibrant, bright red lips and plump lips, and the demand for related products is increasing.

Lipstick is generally an oil-based formulation and contains wax, oil, pigment, and powder. The wax maintains the appearance of the lipstick, the oil provides a rich feeling and a glossy feel, the pigment expresses color as a pigment and/or dye, and the powder improves spreadability, adhesion, and durability and provides a matte feeling when used. use for

Makeup trends change with the times, and until the 1990s, lipstick had a matte and opaque finish, but in the 2000s, lip gloss or lip tint emphasized transparency and moisture. The lip gloss or lip tint has the advantage of being thin and light to use, but has the problem of poor color persistence and adhesion and being easily erased.

Recently, many liquid lip cosmetics containing volatile oils have been developed for high color durability. Although these liquid lip cosmetics have high color persistence, they have the limitation of causing dryness and uncomfortable touch due to the film former and powder that remain after the volatile oil volatilizes. In addition, liquid lip cosmetics have the disadvantage of making it difficult to control the amount of application.

By including a high content of wax to make lipstick, problems such as dryness, uncomfortable touch, and difficulty in controlling the amount of application can be solved to some extent. However, due to the highly volatile nature of oil, it is difficult to form high hardness due to poor compatibility with most waxes. , In addition, in the case of waxes with high hardness, volatile oils may volatilize during the process, making it difficult to use them together.

In order to solve the problems of conventional cosmetic compositions, a cosmetic composition for lips was studied by the present inventors.

One embodiment is to provide a cosmetic composition for lips with excellent color persistence and excellent sensory properties such as a light feeling of use.

Another embodiment is to provide a cosmetic product made by formulating the cosmetic composition for lips.

According to one embodiment, two volatile oils; wax; silsesquioxane; And it provides a cosmetic composition for lips containing an oily thickener.

The two types of volatile oils may each independently have a viscosity of 0.5 cST to 2 cST at 20°C.

The two types of volatile oils may each independently have a boiling point of 100°C to 250°C.

The two types of volatile oils may be included in an amount of 10% to 70% by weight based on the total amount of the lip cosmetic composition.

The two volatile oils may be dimethicone and trisiloxane.

The dimethicone and trisiloxane may be included in a weight ratio of 8:2 to 5:5.

The wax may have a melting point of 60°C to 90°C.

The wax may include polyethylene, synthetic wax, candelilla wax, ozokeride, bead wax, or a combination thereof.

The silsesquioxane may be alkyldimethylsilyl polypropyl silsesquioxane having 30 to 45 carbon atoms.

The silsesquioxane may be included in an amount of 0.1% to 5% by weight based on the total amount of the lip cosmetic composition.

The oil thickener may be glyceryl behenate/eicosadioate.

Another embodiment may be a cosmetic product made by formulating the cosmetic composition for lips.

The cosmetics may have a hardness of 50gf to 120gf.

The cosmetic product may be lipstick or lip balm.

The cosmetic composition for lips according to one embodiment can provide cosmetics such as lipstick that contain volatile oil and wax, have high hardness, and have excellent color persistence and sensuality.

Hereinafter, embodiments of the present invention will be described in detail so that those skilled in the art can easily implement the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein.

In this specification, when a part of a layer, membrane, region, plate, etc. is said to be “on” another part, this includes not only the case where it is “right on” the other part, but also the case where there is another part in between. Conversely, when a part is said to be “right on top” of another part, it means that there is no other part in between.

Unless otherwise defined herein, “combination” means mixing or copolymerization. Additionally, “copolymerization” refers to block copolymerization to random copolymerization, and “copolymer” refers to block copolymerization to random copolymerization.

Hereinafter, a cosmetic composition for lips according to one embodiment will be described.

A cosmetic composition for lips according to one embodiment includes two types of volatile oils; wax; silsesquioxane; and oil thickeners.

In the case of conventional cosmetic compositions, especially cosmetic compositions for lips, liquid products using a high content of volatile oil have recently been widely used for high color persistence. This is due to the film former and powder remaining on the lips after the volatile oil is volatilized. There is a problem of lingering dryness and uncomfortable touch. There have been attempts to manufacture lipsticks in the form of solid sticks by adding wax, but most volatile oils do not have good compatibility with wax (in particular, volatile oils may volatilize during the process), so they are manufactured in the form of solid sticks. It was very difficult to manufacture.

However, according to one embodiment, two types of volatile oils are used together with wax instead of alone, and silsesquioxane and an oil thickener are additionally used to increase compatibility between the two types of volatile oils and wax to achieve high hardness. For example, it is possible to manufacture a solid stick product having a hardness of 50 gf to 120 gf, and further, by using the oil thickener, the sticky and unpleasant feel caused by the silsesquioxane can be reduced and the spreadability can be further improved. there is.

For example, the two types of volatile oils may each independently have a viscosity of 0.5 cST to 2 cST at 20°C. Additionally, the two types of volatile oils may each independently have a boiling point of 100°C to 250°C. When the two types of volatile oils each independently have a viscosity and/or boiling point in the above range, after applying the cosmetic product prepared by formulating the cosmetic composition for lips according to one embodiment to the lips, the corresponding ingredient may volatilize. It has excellent adhesion or fixation power to pigments and other ingredients remaining on the lips, improving the sustainability and adhesion of cosmetics. Conversely, when non-volatile oils, such as non-volatile oils that do not have a viscosity and/or boiling point in the above range, are used, color persistence and adhesion are reduced, which is not desirable.

The two types of volatile oils may be included in an amount of 10% to 70% by weight, for example, 20% to 50% by weight, based on the total amount of the lip cosmetic composition. When the two types of volatile oils are included in less than 10% by weight based on the total amount of the lip cosmetic composition, the color persistence and adhesion effects are not sufficient, and the two types of volatile oils are contained in an amount of 70% by weight based on the total amount of the lip cosmetic composition. If it is included in excess of weight percent, the volatility of the entire composition increases, making it difficult to secure process stability and stability.

The two volatile oils may be dimethicone and trisiloxane. For example, the dimethicone and trisiloxane may be included in a weight ratio of 8:2 to 5:5. That is, the two types of volatile oils in the lip cosmetic composition according to one embodiment may be a mixture of dimethicone and trisiloxane in a weight ratio of 8:2 to 5:5. When the dimethicone and trisiloxane are included in the above weight ratio, excellent high color persistence can be maintained while maintaining process stability.

For example, it is not desirable to use dimethicone or trisiloxane alone as volatile oils used in the lip cosmetic composition according to one embodiment. When the dimethicone is used alone as a volatile oil, it has poor compatibility with the wax described later and does not mix well. However, this problem can be solved when dimethicone is used in combination with trisiloxane. In addition, when the trisiloxane is used alone as a volatile oil, it has low skin safety and is therefore unsuitable for use on the lips. This can also be solved by using trisiloxane together with dimethicone.

The wax may have a melting point of 60°C to 90°C. In general, the higher the melting point, the higher the molecular weight and hardness of the wax. If the melting point is less than 60℃, the wax cannot have a hardness high enough to form a lipstick, that is, a hardness of 50 gf to 120gf, and if the melting point is over 90℃, the wax To melt it, a high temperature process of 95°C or higher is required, which is undesirable because most of the highly volatile oil volatilizes.

For example, the wax may include polyethylene, synthetic wax, candelilla wax, ozokerite, bead wax, or a combination thereof.

The silsesquioxane may be alkyldimethylsilyl polypropyl silsesquioxane having 30 to 45 carbon atoms. Alkyldimethylsilyl polypropylsilsesquioxane having 30 to 45 carbon atoms can help form a lipstick with high hardness by increasing compatibility between the volatile oil and wax.

The silsesquioxane may be included in an amount of 0.1% to 5% by weight based on the total amount of the lip cosmetic composition. Since the silsesquioxane provides a sticky feel, when used in high amounts in the manufacture of solid cosmetics such as lipstick, it causes an unpleasant touch and reduces the feeling of use, so it is appropriate to use it in the above content range.

The oil thickener may be glyceryl behenate/eicosadioate. The oil thickener not only helps form a lipstick with high hardness by increasing compatibility between the volatile oil and wax, but also reduces the sticky feel caused by the aforementioned silsesquioxane and improves spreadability.

The cosmetic composition for lips according to one embodiment may use the above composition along with oils, pigments, and other additives used in conventional cosmetic compositions for lips.

Oils used in the lip cosmetic composition according to one embodiment include ester-based oils, hydrocarbon-based oils, natural oils, and mixtures thereof that are generally used in lip cosmetics. Specifically, mineral oils such as liquid paraffin; animal oils such as squalene and hydrosqualene; Vegetable oils such as palm oil, avocado oil, jojoba oil, sesame oil, olive oil, and castor oil; Butyl myristate, isopropyl myristate, cetyl myristate, isopropyl palmitate, butyl stearate, diisostearyl maleate, polybutene, polyisobutene, hydrogenated polyisobutene, various polyols, tri-2-ethylhexane. Synthetic oils such as glycerin silica, triglyceride-based oil, myristyl lactate, octyl dodecanol, dicaprylyl carbonate, and diisostearyl malate can be used, but are not limited to these.

The oil is used to provide a feeling of use and moisturization to the product and to ensure uniform mixing with other compositions, and may be included in an amount of 40% to 80% by weight based on the total amount of the cosmetic composition for lips. If the content of the oil is less than the above range, the above-mentioned effects cannot be secured. Conversely, if the content of the oil exceeds the above range, formulation is difficult, so it should be used appropriately within the above range.

Additionally, the cosmetic composition according to one embodiment may further include a pigment. For example, the pigment may be included in an amount of 1% to 30% by weight based on the total amount of the cosmetic composition. For example, the colorant may be powder, pigment, etc., and the powder ingredient may be powder commonly used in cosmetics, such as muscovite, synthetic mica, sericite, kaolin, titanium dioxide, titanium oxide coated mica, aluminum powder, iron sulfate. , inorganic powders such as black iron oxide, carbon black, barium sulfate, silica, and zeolite; And organic powders such as nylon, PMMA, polystyrene powder, polyethylene powder, and cellulose powder can be used, but are not necessarily limited thereto.

In addition, the above pigments include Yellow No. 203, Yellow No. 4, Yellow No. 5, Yellow No. 201, Yellow No. 204, Red No. 103, Red No. 201, Red No. 202, Red No. 218, Red No. 220, Red No. 223, Barium or aluminum lake organic pigments and pearl pigments such as Red No. 226, Red No. 227, Blue No. 1, and Blue No. 2 can be used, but are not necessarily limited thereto.

In addition, the cosmetic composition according to one embodiment may further include butter, moisturizer, antioxidant, preservative, fragrance, etc., and the butter, moisturizer, antioxidant, preservative, fragrance, etc. may be those conventionally used.

For example, butter can be various types of butter, such as shea butter, murmur butter, cocoa butter, olive butter, or babassu butter. In addition, polyols such as butylene glycol, propanediol, dipropylene glycol, and pentylene glycol can be used as moisturizers. The content of the other additives is not particularly limited in the present invention, and can be appropriately adjusted and used by those skilled in the art.

The lip cosmetic composition according to one embodiment can be formulated into lipstick, liquid rouge, lip gloss, etc., as described later, by undergoing processes such as heating, mixing, and stirring according to a conventional manufacturing method.

For example, two types of volatile oils, wax, silsesquioxane, and an oil thickener are placed in a mixer, heated to a certain temperature, stirred, then pigments, fragrances, and other additives are added thereto and mixed uniformly, It is manufactured by cooling the obtained mixture, defoaming it, and filling it into a container.

At this time, examples of the mixer include, but are not limited to, a Henschel mixer, universal mixer, homogenizer, wet universal mixer, or kneader.

In addition, the heating is performed at a temperature of 60°C to 95°C so that each composition can be sufficiently mixed, and the stirring is appropriately adjusted depending on the size of the mixer and the content of the composition.

The cosmetic composition for lips according to one embodiment is not particularly limited in its formulation, but includes all types of formulations that can be used on the lips, for example, lip gel, lipstick, lip gloss, lip balm, or lip pencil. It can be, and preferably lipstick.

That is, according to another embodiment, a cosmetic product made by formulating the cosmetic composition for lips is provided.

The cosmetic may have a hardness of 50 gf to 120 gf, for example, 60 gf to 100 gf. If the cosmetic has a hardness lower than 50 gf, formulation stability is poor, and if the cosmetic has a hardness higher than 120 gf, the tactile feel upon application is not good, which is not desirable.

Hereinafter, the contents of the present invention will be described in more detail through examples and comparative examples. These examples are provided to understand the content of the present invention, but the scope of the present invention is not limited to these examples and test examples, and modifications, substitutions, and insertions commonly known in the art can be performed. It can be done, and this is also included in the scope of the present invention.

Test Example 1: Color Persistence

Examples 1 to 7 and Comparative Examples 1 to 5 prepared in the above Preparation Example were applied to the parafilm the same number of times, covered with a tissue after 1 minute, and then applied using a roller capable of pressing with the same weight. I rolled it and stamped it. The color difference value when first applied to the parafilm was compared with the color difference value (dE) after printing with a tissue, and the results are shown in Table 3 below.

Example Comparative example One 2 3 4 5 6 7 One 2 3 4 5 dE 1.03 0.87 0.95 1.16 1.24 2.86 1.4 stick formation x 2.4 3.8 stick formation x 2.91

From Table 3, it can be seen that Examples 1 to 7 (in particular, Examples 1 to 3) have a smaller difference in color difference than the lipsticks according to Comparative Examples 1 to 5, and thus have excellent color persistence. On the other hand, because Example 6 had a low content of volatile oil, it is difficult to say that the color persistence was significantly superior to that of the comparative example.

Test Example 2: Sensory

Each of Examples 1 to 7 and Comparative Examples 1 to 5 prepared in the above Preparation Examples was evaluated for spreadability, color expression, color development, dryness, and overall feeling of use. The evaluation targets are single and married women aged 24 to 35, with at least 2 years of makeup experience, and who consistently use lip products at least 5 times a week. 10 expert panelists rated each item on a 5-point scale (1 point: very It was compared and evaluated as bad, 3 points: average, 5 points: very good. At this time, commercialization is possible if all values score 3 or more, and the results are shown in Table 4 below.

Example Comparative example One 2 3 4 5 6 7 One 2 3 4 5 Spreadability 4.3 4.2 4.3 4.2 4.3 4.0 4.8 - 4.7 4.0 - 3.4 color expression 4.3 4.5 4.5 4.4 4.1 3.5 3.2 - 3.2 3.4 - 4.1 Color development 4.0 4.4 4.3 3.8 4.2 3.8 2.8 - 2.7 3.2 - 3.7 dry 4.1 4.0 3.8 3.3 3.2 4.0 2.6 - 1.9 2.6 - 3.0 Overall feeling of use 4.0 4.2 4.1 3.9 4.0 3.8 3.3 - 2.8 3.0 - 2.5

From Table 4, it can be seen that Examples 1 to 7 (particularly, Examples 1 to 3) enable high color expression and improve dryness compared to the lipsticks according to Comparative Examples 1 to 5, etc. You can see that the feeling of use is excellent.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements can be made by those skilled in the art using the basic concept of the present invention as defined in the following claims. It falls within the scope of invention rights.
