Mascara Composition For Excellent Reapplication

The present invention relates to a mascara composition having excellent spreadability, and more particularly, to a soap which is a fatty acid ester, that is, a triethanolamine-fatty acid ester mixture obtained by reacting a fatty acid with a fatty acid and a non-reacted fatty acid. It stabilizes the system and uses high-grade fatty alcohols as an oil-free wax without any other emulsifiers. It has excellent spreadability due to its smooth and uniform coating. It also contains alumina powder, which is a plate powder, to smoothly spread the eyelids. The present invention relates to a mascara composition having excellent persistence without bleeding.

In general, the purpose of using mascara is to express the beautiful eyes by complementing or emphasizing the disadvantages of their eyebrow shape. The main attributes of mascara are largely divided into volume expression, curling force, long lash force, waterproof expression, etc., and applicability, and persistence. In general, customers have found that when they apply mascara to their inner brows, they apply several times from as many as tens to as many as fifty times, until they form the desired eyebrows. It is an excellent mascara.

In mascara, applicability can be defined as initial application and extra application according to the order of application. 'Initial application' is defined as the act of applying mascara liquid to the eyelashes only once, and 'over application'. Is defined as the act of applying several times over several hundred to hundred times over an initial application. It is possible to finally apply uniformity only when the application is excellent, but conventionally, various methods have been developed only for the mascara having excellent initial application.

Conventionally, Korean Patent Laid-Open Publication No. 10-2003-0003362 includes A) wax to form a uniform coating film to improve applicability. B) fatty acids; C) olive oil derived emulsifiers; D) water soluble thickeners; E) film formers; And F) a mascara composition comprising a pigment, wherein the mascara composition initially forms a uniform coating film and has excellent initial spreadability, but due to the thick film of the film forming agent and the wax of the film-forming agent, the final spreadability is insufficient. There is a disadvantage in that the agglomeration phenomenon is not excellent because of the application.

On the other hand, in the prior art to prevent the spread of mascara and to give the persistence to the film-forming polymer (polyvinyl alcohol, polyvinyl acetate, polyvinyl pyrrolidone, acrylate copolymer, alkyl acrylate copolymer emulsion, ammonium Acrylate copolymer, FV / Eicosin copolymer) is most used, but this has the advantage of imparting durability, but also has the disadvantage of worsening the final spreadability by worsening the additional spreadability. If the spreadability is lowered and the spreadability is bad, a uniform coating film may not be formed, which may result in clumping of eyebrows or powder falling. The powder falling phenomenon is a problem because there is a fear that the foreign matter enters the eye, causing eye irritation. Since the eye is an organ that is more sensitive to irritation from foreign substances than any other part of the human body, mascara products used by women daily should not cause any irritation to the eyes and the skin around the eyes.

In addition, the Republic of Korea Patent Publication (application number: 10-2003-0062066) describes a technique using a fatty acid ester yi-stearate, but it is used for the purpose of improving uniform applicability by making it adhere well to keratin materials with high adhesiveness It was. However, keratin, which is the main component of the eyebrows, can be attached well to the eyebrows evenly. However, when the ester tee-stearate is used as a wax, there is a disadvantage of swelling. In addition, the Republic of Korea Patent Publication (Application No .: 1999-0049959) describes a fatty acid ester tee-stearate and mascara composition using a film-forming agent in order to prevent the resulting eye bleeding and to enhance the persistence, curling, volume. However, this also gives a persistence, but also has the disadvantage of lowering applicability.

Therefore, the present invention has developed a mascara having excellent spreadability and no eye bleeding by using alumina powder, which is a plate-shaped powder instead of a film forming agent, to compensate for the disadvantages of bleeding and powder fall.

On the other hand, another factor to be considered as a cause of lowering the mascara's applicability is a drop in applicability due to the firmness of the contents of the oil-in-water mascara. Due to the characteristics of the oil-in-water mascara, the water, which is a trauma of the mascara liquid, evaporates during use, causing the mascara liquid to harden and spread evenly. In order to solve this phenomenon, a technique for improving the spreadability by preventing moisture from evaporating water that has been conventionally provided has been invented. (Korean Patent Application Publication No. 10-2003-0091925)

Accordingly, the present inventors have studied a method for solving the problems of powder fall-out and under-eye bleeding over time in the oil-in-water mascara containing no liquid crystal base, while improving the spreadability, that is, the spreadability. Triethanolamine-fatty acid ester mixture containing unreacted fatty acid was used by reacting triethanolamine with fatty acid to stabilize the system while giving a soft feeling without the use of nonionic surfactant used as an emulsifier to stabilize the system. By using a combination of higher fatty alcohols as a wax, the alumina powder, which is a plate powder, is added to improve the spreadability due to the smooth and uniform application, and to compensate for the shortcomings of the bleeding caused by the soap of the triethanolamine-fatty acid ester. By using it, eyes bleeding The result is a highly sustainable mascara composition.

Therefore, an object of the present invention is to mix triethanolamine-fatty acid ester mixture and higher fatty alcohol containing unreacted fatty acid by reacting triethanolamine with fatty acids to improve the spreadability as well as to prevent eye bleeding or powder falling out. In order to provide a mascara composition containing alumina powder, which is a plate-like powder, has a smooth spreadability and persistence, and a clean makeup lasts for a long time.

In order to achieve the above object, the mascara composition of the present invention is obtained by reacting a soap, that is, a triethanolamine, with a fatty acid and a fatty acid ester without using a nonionic surfactant and other emulsifiers, and containing unreacted fatty acid. Triethanolamine-fatty acid ester mixtures; Higher fatty alcohols; And alumina powder which is a plate-like powder.

Hereinafter, the present invention will be described in more detail.

The present invention is an oil-soluble wax obtained by reacting a fatty acid ester soap, ie, triethanolamine with a fatty acid, and stabilizing the system with a triethanolamine-fatty acid ester mixture containing unreacted fatty acids, and excellent in spreadability. By using a mixture of higher fatty alcohols, and further contains alumina powder, which is a plate powder, to smoothly apply, as well as to provide a mascara composition with excellent spreadability and long lasting due to no bleeding phenomenon.

Soap, a fatty acid ester used in the present invention, that is, a triethanolamine-fatty acid ester mixture obtained by reacting triethanolamine with a fatty acid and containing an unreacted fatty acid is used in place of an emulsifier used in a conventional mascara composition. The fatty acids used are fatty acids having 14 to 22 carbon atoms, preferably fatty acids having 16 to 18 carbon atoms. Most preferably, palmitic acid and stearic acid are used, and when the carbon number of the fatty acid is less than 14 or more than 22, it is not preferable in mascara formulation because it is not excellent in hardness and usability.

The triethanolamine-fatty acid ester mixture containing the unreacted fatty acid is obtained by reacting a fatty acid with triethanolamine in a ratio of 1: 0.7-1: 0.98 in an amount ratio of 2 to 30% by weight based on the total amount of the unreacted fatty acid. It contains. When the triethanolamine is used in an amount less than 0.7 equivalent to the fatty acid, the neutralization ratio between the triethanolamine and the fatty acid is less than 30%, which is inadequate to act as an emulsifier, resulting in poor phase stability due to poor stability of the mascara, and triethanolamine as a fatty acid. When used in an amount exceeding 0.98 equivalent ratio, the neutralization ratio between triethanolamine and fatty acids exceeds 98%, resulting in an excellent stability of mascara. However, the hardness is so high that the coating properties are lowered and do not apply uniformly.

The amount of the triethanolamine-fatty acid ester mixture obtained by reacting the triethanolamine with a fatty acid and containing 2 to 30% by weight of the total fatty acid is 1 to 15% by weight based on the total mascara composition, most preferably. Preferably 3 to 9% by weight. If the amount of the triethanolamine-fatty acid ester mixture containing the unreacted fatty acid is less than 1% by weight, there is a problem in that the phase is not stabilized due to stabilization of the system, whereas when used in excess of 15% by weight, There is a problem of being stiff.

The mascara composition of the present invention further contains higher fatty alcohols in addition to the use of the triethanolamine-fatty acid ester mixture to further improve applicability. The higher fatty alcohols include cetyl alcohol, stearyl alcohol, isostearyl alcohol, behenyl alcohol, etc. according to carbon number, and are used as an emulsifying stability aid in addition to the oil-soluble wax in the present invention. It is preferable that it is a saturated fatty acid alcohol of 22.

The higher fatty alcohols used in the mascara composition according to the present invention are generally known as Lanette 18, Nasol 18-94 alcohol, Nacol 18-98 alcohol, Nacol 18-99 alcohol, Lipo chemical, and Lanette 18, by Sasol germany GmbH-Hamburq. The behenyl alcohol series (Behenyl alcohol 60, 70, 80, etc.) by Kokyu Alcohol Koqyo, the behenyl alcohol series (Nikko behenyl Alcohol 65,80) by Nikko Chemical, and Lanette 22 by Cognis are marketed.

When the carbon number of the higher fatty alcohol is less than 18, it is preferable to use a fatty alcohol having a carbon number of 18 or more because the carbon length is short and does not play an excellent role in application. In the case of the fatty acid alcohol having 18 or more carbon atoms, the lamellar structure is more easily formed, and the formed lamellar structure is easily broken by external stress (shear shinning effect). This has the advantage of being excellent.

The higher fatty alcohol having 18 to 22 carbon atoms is contained in 0.5 to 30% by weight, most preferably in 3 to 10% by weight based on the total mascara composition. If the content is less than 0.5% by weight, the amount of higher fatty alcohols used is less than the smooth feeling of use of carbonic acid alcohol having 18 to 22 carbon atoms can be expressed, and if the content exceeds 30% by weight, the mascara formulation is hardened and applied rather hardly. There is a problem.

The mascara composition according to the present invention further contains alumina powder, which is a plate powder, in addition to the mixed use of the triethanolamine-fatty acid ester mixture and a higher fatty alcohol, in order to simultaneously provide additional spreadability and durability.

In the mascara composition, in order to eliminate eye bleeding and powder falling phenomenon, in the past, most of the polymer was used as a film-forming agent in order to impart sustainability. However, when the film-forming agent is used, the spreadability decreases, so the film-forming agent is used in the present invention. Persistence was imparted by using an absorbent instead. Generally, powders that act as absorbers include aluminum oxide, aluminum silicate, bentonite, calcium silicate, cellulose, hectorite, kaolin ( kaolin), talc, zinc zeolite, etc., but there are several types, but in the present invention, alumina oxide (Aluminum Oxide), which is a plate powder having excellent durability and abrasion resistance, is used.

Since the plate-like powder has a very thin powder, it is applied thinly to the eyelashes, and its adhesion area is wide, so there is little powder falling off over time, and it is very soft and smooth due to the smooth surface characteristics. It has an advantage.

The alumina powder (Al ₂ O ₃ ), which is a plate-like powder used in the present invention, used the Alusion of Advanced powder Technology, and generally Alumina series (Activated 4082, Calcined 612, Tabular 635, etc.) of Whittaker, Clark & Daniels. In addition, the powders are prepared and marketed in various ways depending on the content composition.

The mascara composition according to the present invention contains the alumina powder (Alusion), which is the plate powder, in an amount of 1 to 10% by weight based on the total mascara composition, and when the content is less than 1% by weight, the amount is too small, due to the absorbency of the powder. It is not expected to improve the sustainability without bleeding, and when it is used in excess of 10% by weight, the viscosity and hardness are so high that the smooth and soft application property is reduced, and the creamy viscosity is suitable for applying to the eyelashes. There are disadvantages that are difficult to maintain.

Hereinafter, the present invention will be described in detail with reference to Examples and Experimental Examples, but the present invention is not limited only to these examples.

Then, after soaking in water for 10 minutes, it was taken out and the state of the glass plate was observed. In the mascara composition applied to the glass plate, less than 10% of the total coating area is in water, and good if 10 to 20% is in water.

(2) oil resistance measurement

After applying the mascara compositions of Examples 1 to 3 and Comparative Examples 1 and 2 to the glass plate in the same thickness by using an applicator, the glass plate was completely dried and placed in silicone oil three times to observe the state of the glass plate. . Then, after soaking in silicone oil for 10 minutes, it was taken out and the state of the glass plate was observed. In the mascara composition applied to the glass plate, less than 10% of the total application area is separated from the silicone oil, and good if 10 to 20% is separated from the silicone oil.

TABLE 4

As can be seen from Table 4, the mascara composition of Examples 1 to 3 was excellent in both water resistance and oil resistance compared to the comparative example, it can be seen that the mascara composition of the present invention is excellent in sustainability.

Experimental Example 4 Powder Falling Measurement

In order to compare the powder falling phenomenon of Examples 1 to 3 and Comparative Examples 1 and 2, the powder falling of each composition was measured according to the following method, and the results are shown in Table 5.

Apply a certain amount of the contents to the false eyelashes, completely dry them, cover a 10X10 size paper on the false eyelashes, apply a constant weight force (repeat 3 times with a 5kg roulette), and observe the condition on the paper. It was. After that, the state of false eyelashes was observed. In the content applied to the false eyelashes, it is good if less than 10% of the total application area is on paper, and if 10 to 20% is on paper, it is generally considered bad if more than 20% is on paper.

TABLE 5

As can be seen from Table 5, the mascara composition of Examples 1 to 3 was excellent in both the spreadability and powder falling off. From this, it can be seen that the mascara composition of the present invention is excellent in sustainability without a powder falling phenomenon and also has good applicability.
